    The Influence of Chocolate and Wafer on customers: An Application of Kansei Engineering2011Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    This project has been assigned for the thesis group by one of the leading Swedishconfectionery company Cloetta AB, and the main goal of this work has been to investigate“What feelings trigger more chocolate in wafer-based chocolates” with chocolate consumers.The Kansei Engineering study was used to achieve this and should deliver useful informationfor the market research and the development department at Cloetta AB.The Kansei Engineering methodology origins in Japan and is about gathering and analyzinginformation from the customer impressions and feelings about a certain product. Gatheredresults considering the physical properties and customer’s impressions are analyzed in relationto each other through various statistical methods.In practice this project has been executed through planning and performing surveys onchocolate consumers and the gathered data has later been analyzed accordingly to the KanseiEngineering Methodology. Statistical methods such as factor analysis using the statisticalsoftware SPSS and regression analysis using QTI through KESo software have been utilizedfor the analysis.In the factor analysis the so-called Kansei-words, which describe impressions of the waferbasedchocolates, were reduced from twenty to five words; preferable, lifestyle, disadvantage,rewarding and quality. These words were connected with the properties given from CloettaAB; number of wafers and amount of chocolate; and used in the final survey. The factoranalysis also included benchmarking of several competing products within wafer-basedchocolates.The final survey resulted in nine varieties of chocolate samples, all with varieties in thenumber of wafers and the amount of chocolate. Input data from this survey was handledwithin KESo software and analyzed with the QTI method.The results were comprehended and interpreted in text format and delivered to Cloetta AB.From the QTI results it may be concluded that feelings which trigger more chocolate amountin wafer-based chocolates are preferable, rewarding and quality.

    Utveckling av skyddsväst för jakthundar mot rovdjursangrepp2011Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Varje år skadas eller dödas hundar av rovdjur i samband med framförallt jakt. Olyckorna leder till debatter angående rovdjurens vara eller inte vara. Detta arbete utreder möjligheterna till skydd för dessa hundar. Skyddsmetoden som utreds är en väst som utlöser en elektrisk puls vid ett angrepp. Tanken är att oavsett var på västen ett angrepp sker så ska en spänningsstöt utlösas vilket ska få angriparen att släppa taget. Arbetet är en vidareutveckling av ett koncept som tagits fram av Prodelox AB i Linköping.

    Konceptframtagandet följer en systematisk konceptutveckling där arbetet delas in i olika faser för att på ett överskådligt sätt komma fram till en prototyp. Första fasen undersöker hur marknaden ser ut på liknande produkter och mynnar ut i en kravkriterielista där produktens funktionalitet specificeras. Andra fasen delar upp huvudprodukten i mindre grenar som åskådliggörs i ett funktion/medels- träd. Sista fasen genererar ett antal olika koncept som utvärderas varav ett koncept går vidare till prototyptillverkning.

    Rapporten beskriver arbetet fram till en prototyp där önskade funktioner är implementerade, prototypen kommer ligga till grund för beslut om produkten ska utvecklas vidare fram till en färdig produkt.

    Design för ett hållbart liv pågatan: En användarstudie av arbetsflödet i food trucks och belastningen pådess primäranvändare2019Självständigt arbete på grundnivå (kandidatexamen), 12 poäng / 18 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Street food är en växande marknad i Sverige och ger små egenföretagare stor frihet kring hur de vill utforma sin verksamhet. För att orka driva en restaurang på ett arbetsmiljömässigt hållbart sätt behöver street food-anordningens design tas i beaktning. Arbetsflödet i köket ska förutom att vara effektivt utformas så att belastningen på primäranvändaren är skonsam. Rapporten undersöker hur dagens street food-lösningar ser ut och genom användarstudier kartläggs tre stycken food trucks. Genomförda intervjuer och observationer ger utrymme för länkanalyser kring arbetsflödet och hur primäranvändaren disponerar tiden i vagnen. Arbetscykler, arbetsrörelser och belastningen i den arbetandes stående kroppsposition riskbedöms och utifrån det kan jämförelser dras om vad som fungerar bra i en food truck- design och vad som inte gör det. Resultatet sammanställs i förbättringsåtgärder och rekommendationer att tänka på vid utformning av en framtida street food-lösning.

    Studien visar att effektiviteten ökar med antalet medarbetare samtidigt som det innebär en större risk för repetitivt arbete och begränsar rörelseutrymmet. Dessutom förekommer låsta eller obekväma arbetsställningar vid skrymmande köksdesign som hämmar kroppens möjligheter att variera arbetsrörelser. Arbetet i dagens street food-lösningar genomförs stående och primäranvändarens nacke och rygg riskerar belastningsskador om inga åtgärder införs. Belastningen på användarens axlar, armar och ben är låga och inga åtgärder behöver vidtas. Primäranvändarens belastning minskas vid implementering av en serveringshylla och arbetshöjden bör antingen vara justerbar eller anpassas direkt till användarens antropometri. En öppen köksdesign rekommenderas, där placeringen av nästföljande köksstation i flödet är angränsande och en möjlighet till sittande arbetsposition finns.

    Optimerad utformning av vattenrutschbaneelement2018Självständigt arbete på grundnivå (högskoleexamen), 10,5 poäng / 16 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Sweden Hydro Sport AB är en svensk tillverkare av vattenrutschbanor till badhus och äventyrsbad. Då det ställs högre miljökrav på energiförluster i badhus har även kraven på bättre isolering på vattenrutschbanor ökat. Sweden Hydro Sport AB anser att det därför är viktigt att ligga i framkant på den här fronten och ta fram lösningar för att minska värmeförluster i banorna. För att lösa det här finns det olika åtgärder, en lösning är att finna isoleringsmaterial med lägre λ-värde vilket är ett mått på värmeöverföringsförmåga. En till åtgärd är att göra det möjligt att isolera så stor yta av bananelementet som möjligt. I dagsläget tillverkas vattenrutschbanorna som en underdel och en överdel vilket medför att de måste bultas ihop med längsgående flänsar. Det gör att det uppstår köldbryggor över flänsarna och ytorna intill då det ej går att isolera vid de längsgående flänsarna och det behövs utrymme för åtdragning av bultarna som håller ihop banan. Därför undersöktes olika isoleringsmaterial med flexibla egenskaper för att kunna isolera alla typer av vattenrutschbanor, där λ-värde och förmåga att inte dra åt sig fukt var två viktiga parametrar. Det utfördes tester på isoleringsmaterialen för att studera hur mycket fukt materialen tar upp i blöta miljöer.

    För att undvika längsgående skarvar undersöktes möjligheten att tillverka ett solitt banelement utan flänsar. Det krävs att innerformen går att avlägsna från banan när tillverkningsprocessen är färdig. Det undersöktes om det fanns lösningar på innerformar som kan tas isär inåt för att få släpp från innerytan och tas ur den färdiga bandelen. Metoden behöver vara en hållbar lösning inom ramarna för hur företaget arbetar idag. Det tillverkades prototyper och modeller på de koncept som togs fram för borttagbara innerformar. Undersökningar gjordes även för vilka typer av tvärgående skarvar som finns på marknaden idag. Utifrån det utvärderades lösningarna och fyra koncept togs fram.

    Conceptual Design of a Variable Air Inlet, JAS 39 Gripen2015Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The JAS 39 Gripen currently has a static air inlet designed for cooling the engine bay. This inlet has been developed over the years and has consisted of several different solutions. In this master’s thesis an investigation of past and current designs has been conducted in order to develop new concepts with a variable solution. Since the static inlet is designed for a worst case scenario, long duration of flight at low altitudes and high atmospheric temperatures, the cooling produced is not always needed and instead causes an unnecessary amount of drag. Developing concepts with variable solutions would alter the caption area depending on flight case and thereby decrease drag accordingly.

    Both aerodynamic and airworthiness properties are important to consider when developing concepts of an air inlet. Initially a concept generation was conducted in order to create possible concepts for implementation. 14 concepts were generated, evaluated and analyzed resulting in two concepts chosen based on their superior aerodynamic and airworthiness properties. Screening was done with both a Pugh matrix as well as a scoring matrix.

    One of the selected concepts has a similar design to the current scoop inlet, but with a variable solution. The second is a variable NACA duct design. An alternative solution briefly discussed was that of a static design, with different caption areas, attached to the service door depending on location of operation and flight conditions but is only theoretical at this point.

    The advantage of implementing the NACA concept would be the decrease in drag since it is a flush inlet. The weight and radar cross section (RCS) are both considered to be low when compared to the scoop concept. Shortcomings of the NACA concept would include the uncertainty in performance concerning cooling and producing sufficient mass flow, as well as the uncertainty in case of bird strike. The scoop concept is similar to the current design and therefore is a verified design with satisfactory bird strike properties as well as having a high probability of producing sufficient mass flow. When compared to the NACA duct it has disadvantages concerning drag, weight, RCS and foreign object damage.

    Collaborative Multidisciplinary Design Optimization: A Framework Applied on Aircraft Systems and Industrial Robots2013Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    In a product development process, it is crucial to understand and evaluate multiple and synergic aspects of systems such as performance, cost, reliability and safety. In order to improve the foundations for decision-making, this thesis presents methods that are intended to increase the engineering knowledge in the early design phases.

    In complex products, different systems from a multitude of engineering disciplines have to work tightly together. Collaborative design is defined as a process where a product is designed through the collective and joint efforts of domain experts. Thus, a Collaborative Multidisciplinary Design Optimization (CMDO) process is proposed in the conceptual design phase in order to increase the likelihood of more accurate decisions being taken early on.

    To enable higher fidelity based CMDO, it is necessary to validate the tools and models utilized. This can be done with so-called low cost demonstrators. The physical demonstrators increase the engineer’s confidence regarding the final product by validating the models as well as revealing many unknowns and thus further increasing the engineering knowledge.

    The performance of the presented methods is demonstrated with two industrial applications, aircraft conceptual system design and industrial robot design.

    Abstract [en]

    An aircraft is a multifaceted product which requires cooperation between different engineering domains. Therefore, design of an aircraft is essentially a multidisciplinary activity with necessity of integrating dierent design tools to get an optimized product. At Linkoping University, a design framework is being developed to assist in the evaluation and optimization of various aircraft vehicle system architectures with the help of integrating a geometric, aerodynamic and dynamic models early in the conceptual design phase. This framework helps to identify a preliminary system concept for an energy optimized aircraft architecture with the focus on more electrical aircraft. As a case study the performance and geometrical aspects of an EMA (Electromechanical actuator) are evaluated and optimized.

    Abstract [en]

    When conducting design on novel mechatronic products, it can be valuable to test and evaluate the performance and properties of the concepts throughout the design process by producing them as downscaled prototypes, see Jouannet et al. [1]. This is especially true when the product is of unconventional design and the designer can get increased confidence of the proposed concept by testing it as a sub scaled version. Nonetheless, the process of realization of new concept should be done in a rapid fashion in order not to halt the design process and simultaneously increasing explicit knowledge about the concept. A case study will be illustrated which demonstrates how fully automated design and construction of downscaled prototypes is performed.

    Collaborative Multidisciplinary Design Optimization for Conceptual Design of Complex Products2016Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    MULTIDESCIPLINARY design optimization (MDO) has developed in theory andpractice during the last three decades with the aim of optimizing complexproducts as well as cutting costs and product development time. Despite thisdevelopment, the implementation of such a method in industry is still a challenge andmany complex products suffer time and cost overruns.

    Employing higher fidelity models (HFMs) in conceptual design, one of the early and most important phases in the design process, can play an important role in increasing the knowledge base regarding the concept under evaluation. However, design space in the presence of HFMs could significantly be expanded. MDO has proven to be an important tool for searching the design space and finding optimal solutions. This leads to a reduction in the number of design iterations later in the design process, with wiser and more robust decisions made early in the design process to rely on.

    In complex products, different systems from a multitude of engineering disciplines have to work tightly together. This stresses the importance of evolving various domain experts in the design process to improve the design from diverse engineering perspectives. Involving more engineers in the design process early on raises the challenges of collaboration, known to be an important barrier to MDO implementation in industry. Another barrier is the unavailability and lack of MDO experts in industry; those who understand the MDO process and know the implementation tasks involved.

    In an endeavor to address the mentioned implementation challenges, a novel collaborative multidisciplinary design optimization (CMDO) framework is defined in order to be applied in the conceptual design phase. CMDO provides a platform where many engineers team up to increase the likelihood of more accurate decisions being taken early on. The structured way to define the engineering responsibilities and tasks involved in MDO helps to facilitate the implementation process.

    It will be further elaborated that educating active engineers with MDO knowledge is an expensive and time-consuming process for industries. Therefore, a guideline for CMDO implementation in conceptual design is proposed in this thesis that can be easily followed by design engineers with limited prior knowledge in MDO. The performance of the framework is evaluated in a number of case studies, including applications such as aircraft design and the design of a tidal water power plant, and by engineers in  industry and student groups in academia.

    This study investigates the performance of the collaborative multidisciplinary design optimization framework and how it facilitates the knowledge integration process. The framework is used to design and optimize an innovative concept of a tidal water power plant. The case study helps to highlight the challenges that may occur during implementation. The result is presented as a modified framework with less implementation difficulties. The improved framework shows significant reduction in design time and improvement in collaborative design optimization for a design team. The geometry of the product is optimized to minimize weight and maximize the power generated by the turbine with respect to some mechanical constraints.

    Abstract [en]

    When conducting design on novel mechatronic products, it can be valuable to test and evaluate the performance and properties of the concepts throughout the design process by producing them as downscaled prototypes, see Jouannet et al. [1]. This is especially true when the product is of unconventional design and the designer can get increased confidence of the proposed concept by testing it as a sub scaled version. Nonetheless, the process of realization of new concept should be done in a rapid fashion in order not to halt the design process and simultaneously increasing explicit knowledge about the concept. A case study will be illustrated which demonstrates how fully automated design and construction of downscaled prototypes is performed.

    Abstract [en]

    An aircraft is a multifaceted product which requires cooperation between different engineering domains. Therefore, design of an aircraft is essentially a multidisciplinary activity with necessity of integrating dierent design tools to get an optimized product. At Linkoping University, a design framework is being developed to assist in the evaluation and optimization of various aircraft vehicle system architectures with the help of integrating a geometric, aerodynamic and dynamic models early in the conceptual design phase. This framework helps to identify a preliminary system concept for an energy optimized aircraft architecture with the focus on more electrical aircraft. As a case study the performance and geometrical aspects of an EMA (Electromechanical actuator) are evaluated and optimized.

    A Collaborative Tool for Conceptual Aircraft Systems Design2012Ingår i: Guidance, Navigation, and Control and Co-located Conferences: AIAA Modeling and Simulation Technologies Conference / [ed] The American Institute of Aeronautics and Astronautics, Reston, VA, USA: American Institute of Aeronautics and Astronautics, 2012, s. 1-10Konferensbidrag (Refereegranskat)
    Abstract [en]

    Advances in recent years has brought forth many feasible technologies which oer signif-icant design advantages over the traditional aircraft vehicle ight systems. These advanceshave brought about a need for the aircraft conceptual engineers to evaluate these newtechnologies so as to realize a realistic and optimized architecture which fulls all criti-cal disciplinary requirements. To evaluate these systems, it is necessary to use models ofcomplexity which are a degree higher than what is being used today. Quick developmentand evaluation of these models can be a hard task for an engineer to achieve consideringthe multidisciplinary nature of the systems. A collaborative eort in model developmentbetween various department is needed if the conceptual design is to be completed withinthe time frame. To facilitate a collaborative conceptual design a research project was for-malized at Linkoping university, which has led to the development of a tool named CAVE(Conceptual Aircraft Vehicle Engineering) which can be used to evaluate the architectureof aircraft systems. In this paper, CAVE as a conceptual design tool will be presented.

    Abstract [en]

    The aim of this research project is to identify a preliminary architecture of a flight control actuation system concept for energy optimized aircraft system architecture with the focus on more electrical aircraft. At Linköping University a design framework is being developed to assist in the evaluation of aircraft flight system at a conceptual level using dynamic models which has led to the development of a tool named CAVE.

    In this paper the use of the framework to approach the problem of finding a suitable flight actuator system for a number of flight control surfaces distributed over the aircraft with different boundary conditions (maximum torque and flap deflection) is presented. Dynamic models for three of the most commonly used actuation technologies have been developed in Dymola and each system has been optimized with mass and energy consumption as the objectives.

    Design and Evaluation of Airborne Wind Turbine Utilizing Physical Prototype2013Ingår i: International Congress on Energy Efficiency and Energy Related Materials (ENEFM2013): Proceedings, Antalya, Turkey, 9-12 October 2013 / [ed] Ahmet Yavuz Oral, Zehra Banu Bahsi, Mehmet Ozer, Springer, 2013, 1, s. 57-64Kapitel i bok, del av antologi (Övrigt vetenskapligt)
    Abstract [en]

    Moving towards renewable sources of energy has become one of the most important energy-related strategies in recent decades. High-altitude wind power (HAWP) has been discovered in 1833 as a source of useful energy. Wind power density (Watts/m2)  can significantly increase (~6 times) by going from 80 to 500 m altirude The global capacity of 380 TW (terawau) as well as abundance, strength, and relative persistency of wind in higher altitude are eye-catch ing poinls to consider HAWP as a reliable energy source in the future. A research project called "THOR" has been initiated at Linköping University by a group of master students (soon to graduate) as proof of concept of airborne wind energy (AWES). THOR is about feasibility analysis of different concepts of HAWP and proof of concept of balloon based AWES as one of the appropriate existing concepts. THOR is intended to be a research platform at Linköping University for further development of AWES concepts i n future.

    Collaborative multidisciplinary design optimization: A framework applied on aircraft conceptual system design2015Ingår i: Concurrent Engineering - Research and Applications, ISSN 1063-293X, E-ISSN 1531-2003, Vol. 23, nr 3, s. 236-249Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In a product development process, it is crucial to understand and evaluate multiple and synergic aspects of systems such as performance, cost, reliability, and safety. These aspects are mainly considered during later stages of the design process. However, in order to improve the foundations for decision-making, this article presents methods that are intended to increase the engineering knowledge in the early design phases. In complex products, different systems from a multitude of engineering disciplines have to work tightly together. Collaborative design is described as a process where a product is designed through the collective and joint efforts of domain experts. A collaborative multidisciplinary design optimization process is therefore proposed in the conceptual design phase in order to increase the likelihood of more accurate decisions being taken early on. The performance of the presented framework is demonstrated in an industrial application to design aircraft systems in the conceptual phase.

    SolidWorks Parameterization for Industrial Robot Design2010Självständigt arbete på avancerad nivå (masterexamen), 30 poäng / 45 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Development of Industrial robots is becoming more expensive and time consuming over the years. A lot of costs are spent in the development, and so it is necessary to improve the conceptual design phase.

    This thesis is an object lesson that shows one of the multiple ways to improve the named phase.

    It basically consists on, using a CAD program, build a robot whose parameters have to be modified from a user interface. The parameters to change are the dimensions of the robot’s parts (morphology parameterization) and also the parts to use (topology parameterization), which can be chosen from a large library of different parts.

    Some parameters are changed so as the build robot has similar mass properties to a given one, in order to be able to do some tests with it and export the results to improve the real robot. For this reason, in the interface done there is also written some code to get the mass properties of the built robot. Even so, this thesis only shows how to do the named actions but it has not been done any kind of test.

    Design Space Exploration for Structural Aircraft Components: A method for using topology optimization in concept development2019Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    When building aircrafts, structural components must be designed for high strength, low cost, and easy assembly.To meet these conditions structural components are often based upon previous designs, even if a new component is developed.Refining previous designs can be a good way of preserving knowledge but can also limit the exploration of new design concepts.

    Currently the design process for structural aircraft components at SAAB is managed by design engineers. The design engineer is responsible for ensuring the design meets requirements from several different disciplines such as structural analysis, manufacturing, tool design, and assembly.Therefore, the design engineer needs to have good communication with all disciplines and an effective flow of information.

    The previous design is refined, it is then reviewed and approved by adjacent disciplines.Reviewing designs is an iterative process, and when several disciplines are involved it quickly becomes time consuming.Any time the design is altered it has to be reviewed once more by all disciplines to ensure the change is acceptable.So there is a need for further customizing the design concept to decrease the number of iterations when reviewing.

    Design Space Exploration DSE is a well known method to explore design alternatives before implementation and is used to find new concepts.This thesis investigates if DSE can be used to facilitate the design process of structural aircraft components and if it can support the flow of information between different disciplines.To find a suitable discipline to connect with design a prestudy is conducted, investigating what information affect structural design and how it is managed.The information flow is concluded in a schematic diagram where structural analysis is chosen as additional discipline.

    By using topology optimization in a DSE, design and structural analysis are connected.The design space can be explored with regards to structural constraints.The thesis highlights the possibilities of using DSE with topology optimization for developing structural components and proposes a method for including it in the design process.

    Designing Feelings into Products: Integrating Kansei Engineering Methodology in Product Development2002Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Tendencies in product development of today make it likely that many future products will be functional equivalent and therefore hard to distinguish between for the customer. Customers will decide by highly subjective criteria which product to purchase. One task for product development in this context is to be able to capture the customer’s considerations and feelings of products and translate these emotional aspects into concrete product design.

    Today a number of different methods, such as Quality Function Deployment (QFD), Semantical Environment Description (SMB), Conjoint Analysis and Kansei Engineering exist and are used in practical applications.

    The purpose of this thesis is to understand and apply Kansei Engineering methodology and explore ways to integrate the methodology into an industrial product development process.

    This was done by conducting a study on forklift trucks in different European countries and business areas and by exploring ways of integrating Kansei Engineering in product development processes.

    The number of Kansei words collected was reduced based on the result of a pilot study using a combination of different tools. A computerized data collection method was used in combination with a modified VAS-scale in order to reduce the time for filling out the evaluation forms The results of the study in the visited Northern and Middle European companies make it evident that Kansei Engineering has to be adapted in several aspects to the circumstances in each situation. The data showed that there are differences in attitude towards reach trucks in the different European countries. These results were used in order to adapt the product requirements for each specific country. Starting at Cooper’s stage gate model Kansei Engineering was applied on a macro level, a micro level and for verifying purpose. Using QFD, Kansei Engineering helps to identify customer needs their importance and the technical responses as well as to conduct benchmarking and to connect the customer needs mathematically to the technical responses.

    This study of Kansei Engineering revealed that there was no general model on the methodology available in English literature. Outgoing from a previous flowchart, a conceptual framework of Kansei Engineering was developed integrating the existing Kansei Engineering Types and future tools.

    Abstract [en]

    Improvements in the design of products for industrial use gets increasingly important. The aim is to get better knowledge about the user’s feelings about warehouse-trucks and to test study methods . Kansei Engineering is used in order to compare three trucks from different manufacturers and reveal differences in impact on the users. The project contains three studies at European companies, using a modified analogue-visual scale, administered by Excel based software. The results show that there are significant differences between truck traits. All trucks score lower than an "ideal" truck. This shows that even a mature product still has improvement potential.

    Abstract [en]

    Trends in product development today indicate that customers will find it hard to distinguish between many products due to functional equivalency. Customers will, therefore, base their decisions on more subjective factors. Moreover, in the future, products will consist, to a higher grade, of a combination of a tangible and intangible part. Kansei Engineering is a tool translating customer's feelings into concrete product parameters and provides support for future product design. Presently, a total of six different types of Kansei Engineering are in use. The aim of this paper is to propose a framework in Kansei Engineering to facilitate the understanding of the different types of Kansei Engineering and to open Kansei Engineering for the integration of new tools. The new structure includes the choice of a product domain, which can be described from a physical and a semantic perspective as building a vector space in each. For the latter mentioned space, the Semantic Differential Method is used. In the next step, the two spaces are merged and a prediction model is built, connecting the Semantic Space and the Space of Product Properties together. The resulting prediction model has to be validated using different types of post-hoc tests.

    Engineering Emotional Values in Product Design: Kansei Engineering in Development2005Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Feelings and impressions of a product are important for the decision of purchasing it or not. Designing attractive products therefore requires knowledge about the feelings and impressions the products evoke on the customer and the user. Integrating such affective values in product design requires the introduction of suitable methods into companies’ product design processes, methods which can capture and convert subjective and even unconscious feelings about a product into concrete design parameters. This is sometimes referred to as ‘Affective Engineering’. One methodology in this context is Kansei Engineering, which has been developed in Japan in order to design feelings into products. The aim of this thesis was twofold: Firstly, to improve understanding of the nature of products making emotional impact on the users and customers. Secondly, to identify and improve methods capable of grasping those affective values and translating them into concrete product design solutions. This thesis presents three empirical studies and two methodological papers, relating to warehouse trucks and laminate flooring. The first study was made on user impact of warehouse trucks in three different European countries. A second study dealt with affective values of rocker-switches in work vehicles, such as warehouse trucks. A third study on this truck type compared the old manoeuvring panel evaluated in the previous studies with a newly introduced manoeuvring panel in order to validate the impact of the design improvements made after the first study. Further, a conceptual model on Kansei Engineering methodology was proposed in a methods paper based on the experience from the studies performed in order to provide a structure for performing Kansei Engineering studies. The fifth paper had the purpose of validating and improving the proposed model using laminate flooring as research object. More structured ways of identifying design parameters and relevant product properties was given high priority in the improvement work of the methodology. A model for spanning the Space of Product Properties was presented and applied. This thesis also deals with other improvement areas in the methodology and proposed new developments, including the use of scales, experimental design and validation methods. In conclusion, Kansei Engineering is a concept and a methodology in strong development, a framework in which tools and methods are continuously developed, added and integrated.

    Abstract [en]

    Rocker switches used in vehicles meet high demands partly due to the increased focus on customer satisfaction. Previous studies focused on ergonomics and usability rather than design for emotions and affection. The aim of this study was to determine how and to what extent engineering properties influence the perception of rocker switches. Secondary aims were to compare two types of rating scales and to determine consistency over time of the ratings. As a method Kansei Engineering was used, describing a product domain from a physical and semantic point of view. A model was built and validated, and recommendations for new designs were given. It was seen that the subjective impressions of robustness, precision and design are strongly influenced by the zero position, the contact position, the form-ratio, shape and the surface of rocker switches. A 7-point scale was found suitable. The Kansei ratings were consistent over time.

    Abstract [en]

    Trends in product development today indicate that customers will find it hard to distinguish between many products due to functional equivalency. Customers will, therefore, base their decisions on more subjective factors. Moreover, in the future, products will consist, to a higher grade, of a combination of a tangible and intangible part. Kansei Engineering is a tool translating customer's feelings into concrete product parameters and provides support for future product design. Presently, a total of six different types of Kansei Engineering are in use. The aim of this paper is to propose a framework in Kansei Engineering to facilitate the understanding of the different types of Kansei Engineering and to open Kansei Engineering for the integration of new tools. The new structure includes the choice of a product domain, which can be described from a physical and a semantic perspective as building a vector space in each. For the latter mentioned space, the Semantic Differential Method is used. In the next step, the two spaces are merged and a prediction model is built, connecting the Semantic Space and the Space of Product Properties together. The resulting prediction model has to be validated using different types of post-hoc tests.

    Evaluation the affective coherence of the exterior and interior of chocolate snacks2013Ingår i: Food Quality and Preference, ISSN 0950-3293, E-ISSN 1873-6343, Vol. 29, nr 1, s. 16-24Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Scandinavian confectionery market is dominated by three major manufacturers, of whom two are affiliates of international conglomerates and one is a domestic producer. The aim of this study was to map the affective impression of chocolate bars’ exterior and interior and give suggestions for a coherent design. Kansei Engineering was used for this. Products were rated on AVI scales with relevant Kansei words, resulting in affective profile graphs. These data were processed treated using Factor Analysis. Four factors were retrieved: Attraction, Life-Style, Familiarity and Snack. Multiple Regression Analysis and Rough Set Analysis were applied to map relationships between physical attributes and affective values. Attributes with significant affective impact are size, shape, color: and brand (packaging) and Surface roughness, Separation and top- and side-angles (shape). The data were used for successful product development and a product series with coherent attributes was developed. One product is used to illustrate the process. Kansei Engineering proved to be suitable for this task although the results may be biased since the evaluation is based on visual impression only.

    Developing Software Tools for Kansei Engineering Processes: Kansei Engineering Software (KESo) and a Design Support System Based on Genetic Algorithm2006Ingår i: 9th International Quality Management for Organizational Development (QMOD) Conference, August 9-11, Liverpool, England, 2006Konferensbidrag (Refereegranskat)
    Abstract [en]

    Launching products successfully onto today’s markets requires not only good quality and usability for a reasonable price but also that the customer gets a good subjective impression of the product. This is especially true for mature products, which tend to be rather similar to competing products. Designing a good feeling into products is a challenge many companies face today. A new research field is named emotional design or affective engineering. One method within this field is Kansei Engineering, a methodology that can quantify user impressions mathematically. A general procedure for conducting Kansei Engineering studies has been proposed, but still much expert knowledge is necessary for those studies. Therefore, software tools facilitating this process have been developed. In this paper, two tools used at Linköping University are presented. It can be seen that those tools deliver good results and remove many obstacles for applying Kansei Engineering in companies. However, more research is needed on the theoretical bases and extraction methods.

    An Approach to Kansei Engineering-Methods and Case Study on Design Identity2001Ingår i: Conference on Human Affective Design, Singapore June, 27-29, 2001Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Improvements in the design of products for industrial use gets increasingly important. The aim is to get better knowledge about the user’s feelings about warehouse-trucks and to test study methods . Kansei Engineering is used in order to compare three trucks from different manufacturers and reveal differences in impact on the users. The project contains three studies at European companies, using a modified analogue-visual scale, administered by Excel based software. The results show that there are significant differences between truck traits. All trucks score lower than an "ideal" truck. This shows that even a mature product still has improvement potential.

    Ratingscales in Kansei Engineering: Modification for an European Context2010Konferensbidrag (Refereegranskat)
    Abstract [en]

    Kansei or Affective Engineering is a relatively new research field in the West.Linköping University in Sweden has been pioneering research and applicationwithin Kansei Engineering since 1999. Several companies have cooperated indifferent Kansei studies, for example Toyota/BT, Volvo, Saab, Scania. In some of theearly studies, there were difficulties to apply the methodology. Reasons for thisincluded shortage of competence within affective design in European organizations,but also the fact that incitements for improvement of product design seemed to belacking. One of the problems applying the methodology was that Europeanparticipants in the studies did not accept to make a vast number of ratings duringlong time periods. Japanese researchers used 5-point semantic differentialquestionnaires and up to 300 rating-scales per participant and product. In order toovercome this problem, a modification of the rating scales was developed. Hence,data reduction methods such as factor analysis, affinity diagram and Pareto chartswere tested and validated in order to reduce the number of Kansei words andproduct samples used, without compromising the validity of the result. Thisapproach eventually resulted in the development of a universal Kansei EngineeringSoftware (KESo) which reduces the time needed for each Kansei Engineering study.Another objective for our research has been to develop and validate methods forincomplete data collection, i.e. a prioritization of product attributes. Another resultfrom the cooperation with industrial companies is that the companies stronglyemphasised that product development studies need to be less time and resourceconsuming.Keywords:

    Abstract [en]

    The book brings together research that investigates how people experience products: durable, non-durable, or virtual. In contrast to other books, the present book takes a very broad, possibly all-inclusive perspective, on how people experience products. It thereby bridges gaps between several areas within psychology (e.g. perception, cognition, emotion) and links these areas to more applied areas of science, such as product design, human-computer interaction and marketing.The field of product experience research will include some of the research from four areas: Arts, Ergonomics, Technology, and Marketing. Traditionally, each of these four fields seems to have a natural emphasis on the human (ergonomics and marketing), the product (technology) or the experience (arts). However, to fully understand human product experience, we need to use different approaches and we need to build bridges between these various fields of expertise *Most comprehensive collection of psychological research behind product design and usability *Consistenly addresses the 3 components of human-product experience: the human, the product, and the experience *International contributions from experts in the field

    Abstract [en]

    Kansei Engineering is a methodology seeking to grasp customers’ feelings and subjective affective opinion of products as well as turning their affective needs into suitable product concepts. The procedure is rather complex and requires a fair amount of interdisciplinary expertise and experience in order to achieve reliable results. The high threshold to learn those techniques is preventing many practitioners from applying it. There are, however, software packages that have supported product designers to perform Kansei Engineering evaluations without being experts in the field of statistical mathematics. This paper will give a short overview on Kansei procedure, and the methods attached to it, and shows present and future areas of application for computerized tools in Kansei Engineering.

    Abstract [en]

    The Circular-Design - Learning for Innovative Design for Sustainability (L4IDS) project is a three year (2016-2019) Erasmus + Knowledge Alliance financed project. The goal of the project is to promote sustainable consumption and production of products and services in Europe. This is achieved through a knowledge co-creation process and the development of training materials in order to teach and train students, faculty and enterprise staff of the design sector in Innovative Design for Sustainability (IDfS) strategies. The project is aligned with European Circular Economy policies and contributes to the realization of a more sustainable society. There is an abundance of learning schemes, courses, and teaching materials in higher education on DfS but few of these focuses on Knowledge Co-Creation and Innovation and none through continuous professional development. This paper will present an overview of previous initiatives around DfS in higher education, focusing on those that rise above the level of a single institution. By mapping these initiatives on the triangle Design for Sustainability (DfS)-Knowledge Co-Creation - Innovation, we will articulate the gap which the L4IDS project aims to bridge. For this, we will use an adapted version of the DfS Evolutionary framework. The mapping will be based on a case study publication on knowledge co-creation processes in design for sustainability. Specifically, the study will focus on the position of Digital Fabrication Labs (DFL) in this innovative design for sustainability triangle.

    Identification of the mechanical parameters for the human uterus in vivo using intrauterine pressure measurements2017Ingår i: International Journal for Numerical Methods in Biomedical Engineering, ISSN 2040-7939, E-ISSN 2040-7947, Vol. 33, nr 1, s. 1-11Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    There are limited experimental data to characterize the mechanical response of human myometrium. A method is presented in this work to identify mechanical parameters describing the active response of human myometrium from the in vivo intrauterine pressure measurements. A finite element model is developed to compute the intrauterine pressure during labor in response to an increase in the intracellular calcium ion concentration within myometrial smooth muscle cells. The finite element model provides the opportunity to tune mechanical parameters in order to fit the computed intrauterine pressure to in vivo measurements. Since the model is computationally expensive, a cheaper meta-model is generated to approximate the model response. By fitting the meta-model response to the in vivo measurements, the parameters used to determine the active response of human myometrial smooth muscle are identified.

    Conceptual Design of AM Container for “3D-Printer Cloud” Close to Customer Site: Plant-in-the-box2016Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    This is a master thesis about the Plant-in-the-box concept. The master thesis is to develop initial requirements and an initial layout to further investigate the concept. Plant-in-the-box in combination with the Vertical Workshop concept are a part of the “Digitalization @ PS”–Initiative, at Siemens, that started in October 2015 and forms a way of portable and flexible workshops. Plant-in-the-box is based on the idea to have a Additive Manufacturing, AM, machine with all its surrounding systems and equipment in a container which can easily be shipped to a new destination if desired. This AM container can then be combined with other containers containing anything from machinery for cutting processing to desktop stations and equipment for climate control. The set of containers are organized in a Vertical Workshop, where the containers can be slipped into a rack which supports the multi-storage workshop with accessibility and the necessary media. The Vertical Workshop can easily be deployed close to customer and as a part of a 3DPrinter Cloud provide a network of  production units placed on strategic locations.

    Kamratutvärdering i kurser med stort datorlaborativt inslag2014Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    De mångfacetterade krav som idag ställs på yrkesverksamma högskole- och civilingenjörer handlar inte enbart om rena ämnesmässiga kunskaper och förmågor, utan även om t.ex. erfarenhet och förmåga att delta i och leda projekt samt (kopplat till detta) kommunikativ skicklighet (såväl muntlig som skriftlig). En annan uppgift som yrkesverksamma ingenjörer måste kunna bemästra i sin profession är att (individuellt, eller som medlemmar i olika typer av styrgrupper) bedöma och utvärdera andras ingenjörsmässiga arbete, en oerhört central uppgift i ett projekt- och kvalitetssäkringsperspektiv.

    Det övergripande syftet med arbetet har varit att studera hur kamratbedömning kan implementeras i redan existerande kurser, för att på så sätt ge de studerande möjlighet att träna på att ge och ta emot kritisk bedömning, att förbättra de studerandes lärande via ett större aktivt engagemang under kursen samt att se om potential finns att effektivisera undervisningen m.a.p. lärarinsatsen, genom att lyfta över en del av enklare rutinkontroller till de studerande själva.

    Kamratbedömning har implementerats i två sinsemellan likartade kurser inom beräkningsmekanik vid högskole- resp. civilingenjörsprogrammen i Maskinteknik, LiTH (600 studenter ingick i studien). Mer specifikt har till två enklare inledande laborationsuppgifter inkluderats ett moment av kamratbedömning. Utvärderingen av det genomförda arbetet har skett via en kvalitativ studie, där de studerandes perspektiv/synpunkter inhämtats i samband med skriftlig redovisning av inlämningsuppgifter. Utöver detta har den kursansvarige gjort observationer av hur kamratutvärderingsarbetet fortskridit under laborationstid.

    Resultatet visar att de studerande har uppskattat granskningen av såväl det egna som kamraternas arbeten, och att de sett det som ett led i lärandeprocessen. Även professionsperspektivet har lyfts fram där de studerande betonar vikten av moment och uppgifter i utbildningen som har en direkt relevans i det kommande yrkeslivet. Den kursansvariges bedömning är vidare att andelen ”viktiga” och ”relevanta” frågor ökat, vilket ger indikationer på att kamratbedömning kan vara en såväl pedagogiskt som effektivitetsmässigt gynnsam metodik. De studerande har dock upplevt logistiken/administrationen kring kamratvärderingen som i vissa avseenden besvärlig.

    Sammanfattningsvis är det vår slutsats att kamratbedömning har en stor potential att berika utbildningar m.a.p. förmåga till kritisk granskning, djupinlärning och effektivisering, men att verksamheten inte bara skall implementeras kursvis (med risk för suboptimering och ineffektivitet), utan att den bör inlemmas i ett större perspektiv, med progression genom utbildningen som riktmärke.

    Enclosing and Mounting an Electronic Component on Articulated Haulers: A proposition on how to protect, and where to place, an intelligent node on the environmentally harsh exterior of construction equipment with respect to multiple parameters2016Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    As is the case with many other manufacturers of vehicles, Volvo Construction Equipment has a constantly increasing amount of electric and electronic equipment in their articulated haulers. These are of great use in modern machines, bringing functions, and safety that were not possible before, but they also bring more cables to handle.

    In the case of the articulated haulers a quite thick cable harness of about 15 meters in length reaches from the driver’s cabin in the front to the components in the far back end of the vehicle. This is not only a lot of long cables to handle both during assembly and service, but the nature of signals traveling in cables is that the voltage gets weaker with distance. This phenomenon has to be accounted for by measuring devices dependent on the voltage.

    It has been suggested that a device referred to as an intelligent node, or ICCS-module, which communicates digitally via CAN could be installed in the back of the articulated haulers. This module would be independent of the mentioned drop in voltage. The ICCS-module will be receiving a small bundle of cables being routed from the driver’s cabin. From it cables would go out to a majority of the components in its vicinity. The components connected to the node would not need to have any other cables.

    This thesis is focused on the mechanical aspects of installing this ICCS-module. Having electric and electronic equipment on construction vehicles is a challenge when it comes to protecting the device from the harsh environment that is the hauler’s exterior. It will have to withstand being immersed in water for long periods of time, greatly varying temperatures, vibrations and shocks as well as being hit by projectiles. The placement as well as the design of the enclosure should be chosen with respect to both the devices length of life and how well it fulfils its intended role and achieves the expected results.

    To produce an enclosure and find a placement aiming to satisfy these conditions, a traditional product development process were executed. The articulated haulers as well as relevant literature were researched. Concepts were generated and evaluated by both the author and by employees at Volvo Construction Equipment until a final concept for the enclosure and placement were found. The enclosure were then designed in detail specifying the material, manufacturing techniques, controlled for thermodynamic circumstances, modelled in Catia V5 and controlled for vibrations. It was concluded that the enclosure should be able protect the ICCS-module after some more development and that the placement and cable routing results in a much shorter total cable length.

    Diagnostikmetoder för ångreglerventil med servomotor2009Självständigt arbete på grundnivå (högskoleexamen), 10 poäng / 15 hpStudentuppsats
    Abstract [en]

    In this bachelor thesis, diagnostic methods for one of Siemens stem inlet control valves have been developed. The work has taken place during ten weeks at Siemens Industrial Turbomachinery AB in Finspång. The company produce steam- and gas turbines and also provides service and maintenance.

     

    The purpose with this project has been to develop diagnostic methods that oversee the health of the control valves. By using the developed methods you will know when it’s time for maintenance. With these diagnostic methods it’s possible to some degree leave the predetermined maintenance that Siemens uses today on their control valves.

     

    The project has been limited to involve just one of Siemens control valves. The report describes the control valve’s function and the components included in the valve structure. It describes the problems that can occur with the valve and what could be done monitoring it to detect potential failures before they develop into functional failures.

     

    A short description of different measuring equipment and how they work is also included.

     

    Interviews have been conducted at Siemens, at Linköpings University and also with companies that delivers measuring devises. A visit to follow a vibration measurement of a control valve at Idbäcksverket in Nyköping has also taken place. Another tool that has been used in this work is an FMECA that describes errors that may occur with the control valve and what caused them. Books and the internet have also provided necessary facts.

     

    This report presents some recommendations on what to do to monitor health of the control valve and equipment to prevent functional failures. The intention with the report has been to show that the equipment presented here can be used in the future to avoid unnecessary preventive maintenance and eliminate the use of corrective maintenance.

    RAPTOR (Rapid tool for optimized real time concept evaluation): A development tool for early investigations of concepts2009Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats
    Abstract [en]

    Early concept generation is the base for the final products appearance. Since most of the products character and cost is set at an early stage increased knowledge at an early stage is vital. This master thesis aims at creating a method called RAPTOR. The purpose of RAPTOR is to reduce the cost and increase the knowledge by combining CAD and optimization with an easy excel interface.

    For illustrative purpose an electric motor example has been used. The master thesis has been demonstrated at GM power train, Trollhättan Sweden, and a considerable interest was shown.

    The inspiration comes from the GlobaLiTH project, a project at the machine design department at Linköping University, Sweden, where a sustainable light utility vehicle was designed.

    Digital dynamisk geometrisäkring: En kartläggning av dagens arbetssätt2013Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Detta examensarbete innehåller en kartläggning av Scanias arbete med digital dynamisk geometrisäkring samt ett förslag på hur arbetet kan utvecklas.

    Kartläggningen skapar en översiktlig bild av hur dagens arbete utförs och beskriver de ingående delmomenten. Observationer av hur arbetet utförs har gjorts och dokumenterats och samtal med berörda personer på Scania har skapat förståelse för behovet av ett bättre och mer utvecklat arbetssätt.

    Scania vill bli bättre på digital dynamisk geometrisäkring för att kunna minska den idag relativt stora verksamheten med fysisk provning av prototypartiklar och färdiga bilar. Ett förslag till ett nytt arbetssätt har tagits fram och förutsättningar för detta har undersökts på företaget. Förslaget bygger på ett ökat samarbete mellan grupper med olika ansvarsområden kopplade till vilka krav som ställs på lastbilen. Utöver den rent organisatoriska delen innefattar det även mer handgripliga förslag på fortsatt arbete som bland annat behöver ett underlag i form av trovärdiga simuleringsmodeller.

    En jämförelse mellan resultaten från dagens simulering och fysisk provning har genomförts och resultatet visar att vidare arbete med förbättring av de digitala modellerna krävs innan det nya arbetssättet kan anammas tillfullo.

    Parameterized Automated Generic Model for Aircraft Wing Structural Design and Mesh Generation for Finite Element Analysis2011Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    This master thesis work presents the development of a parameterized automated generic model for the structural design of an aircraft wing. Furthermore, in order to perform finite element analysis on the aircraft wing geometry, the process of finite element mesh generation is automated.

    Aircraft conceptual design is inherently a multi-disciplinary design process which involves a large number of disciplines and expertise. In this thesis work, it is investigated how high-end CAD software‟s can be used in the early stages of an aircraft design process, especially for the design of an aircraft wing and its structural entities wing spars and wing ribs.

    The generic model that is developed in this regard is able to automate the process of creation and modification of the aircraft wing geometry based on a series of parameters which define the geometrical characteristics of wing panels, wing spars and wing ribs.Two different approaches are used for the creation of the generic model of an aircraft wing which are “Knowledge Pattern” and “PowerCopy with Visual Basic Scripting” using the CATIA V5 software. A performance comparison of the generic wing model based on these two approaches is also performed.

    In the early stages of the aircraft design process, an estimate of the structural characteristic of the aircraft wing is desirable for which a surface structural analysis (using 2D mesh elements) is more suitable. In this regard, the process of finite element mesh generation for the generic wing model is automated. The finite element mesh is generated for the wing panels, wing spars and wing ribs. Furthermore, the finite element mesh is updated based on any changes in geometry and the shape of the wing panels, wing spars or wing ribs, and ensure that all the mesh elements are always properly connected at the nodes. The automated FE mesh generated can be used for performing the structural analysis on an aircraft wing.

    Development of Steam Turbine Inlet Control Valve for Supercritical Pressure at Siemens Industrial Turbomachinery AB2010Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Utvecklingen inom ångturbiner går mot applikationer med mycket högre ångdata eftersom detta möjliggör en ökad effektivitet. Ångdata refererar till ångans tryck och temperatur. Uppgiften var att generera koncept för inloppsreglerventiler (till ångturbiner) dimensionerade för högre tryck och temperatur jämfört med dagens design. Framtida ångkraftverk som drivs av solenergi, så kallade soltorn, efterfrågar denna prestanda och är en viktig framtida marknad.

    Detta examensarbete vid Linköpings Universitet har skrivits i samverkan med Siemens Industrial Turbomachinery AB. Det genomförda arbetet har innefattat litteraturstudier, funktionsanalys och hållfasthetsanalys, flödesanalys, utvärdering av tätningar och tallriksfjädrar samt framtagning av dimensioneringsunderlag för den framtida reglerventilen. Målet var att finna ett koncept som klarar av dessa nya och högre ångdata och är tåligt beträffande vibrationer.

    Ett systematiskt arbetssätt har anammats under projektet och en detaljerad planering upprättades och uppdaterades kontinuerligt. Viktiga metoder som använts är PDS (Product Design Specification), QFD (Quality Function Deployment), morfologisk matris, relativ beslutsmatris och feleffektanalys. Viktiga program som använts i projektet är Pro/ENGINEER, MATLAB, FloEFD och MS Excel.

    Dagens ventiler är dimensionerade för mycket lägre prestanda än de nya kraven kräver i termer av tryck och temperatur. Det huvudsakliga problemet med den nuvarande designen var att kraven på de öppnande och stängande krafterna, med dessa nya ångdata, blir orimligt höga. Därför har många av de framtagna koncepten utrustats med tryckbalanserande funktion. Denna funktion ger också ett annat önskvärt resultat; vibrationerna (som är källan till många problem med dagens design) kommer även de att reduceras.

    Under den tidiga konceptutvecklingsfasen genererades 15 olika koncept och efter konceptutvärderingen återstod bara tre. Dessa koncept vidareutvecklades inom olika intressanta områden och slutligen valdes ett av koncepten som det vinnande. Den nya ventildesignen kommer med stor sannolikhet att uppfylla kraven och har potential att förfinas för ännu högre tryck för framtida krav.
