Abstract [en]

This contribution will discuss engineering design projects with various environmental and sustainable objectives. The automotive industry is facing a major vicissitude regarding the system layouts of their products. Given the rapidly increasing demands for environmentally acceptable and sustainable vehicles, developed even faster and under increasing competition, one could expect a future, or a period of transition, where a “market pull”-situation will exact design methods more adapted for new propulsion technologies such as fuel cells, bio-fuels, hybrid configurations and so forth. When looking at two-wheeled vehicles it is also a matter of a dramatic change in the safety requirements that would affect the design process in a similar way.

This paper presents studies made regarding development of two-wheeled vehicles with strict safety, environmental and sustainability requirements. It also describes what happens when a very mature product, such as a conventional motorcycle, undergoes dramatic changes in propulsion system and safety features and becomes technically immature, but still has to preserve its traditional values in the eyes of the consumer. Over the last two years, the Department of Mechanical Engineering at Linköping University has conducted various projects dealing with these issues using rapid, low-cost, demonstrator development together with digital models. The demonstrator is used as a vehicle to evaluate the integration of technology, as well as less tangible aspects such as ergonomics, drivability, appeal, visual impression etc. This approach has proven particularly fruitful when dealing with new technologies with a high level of innovation. The rapid nature of these projects also makes them suitable for exploring digital collaboration tools aimed at controlling and speeding up the design process.

Abstract [en]

Ever since the early nineties and the advent of affordable and comprehensive 3D-CAD systems, companies have striven to take advantage of cost-effective Virtual Prototyping, gradually moving away from activities involving physical representations of the evolving product. There are, however, aspects of the product development process that are less suitable for virtual exploration. Thus, there are limits to what extent it is effective to rely on digital modeling of physical products. Instead, this thesis argues that a deliberate combination of physical and virtual modeling offers numerous efficiencies that deserve further investigation.

By studying and combining four domains; product development theory, traditional prototyping, computer aided engineering and learning theory, the concept of low-cost demonstrators are identified as a potential means for further enhancement of the product development process. Especially when developing products involving new and unfamiliar technologies, this approach has proven particularly relevant and beneficial. Furthermore, a low-cost demonstrator can potentially serve as a catalyst for innovation and creativity among the members of the design team operating in a CAE intense environment.

In order to verify the validity of the concept of low-cost demonstrators, several undergraduate courses at Linköping University have been studied and evaluated.

Abstract [sv]

Under första halvan av 1990-talet blev verktyg som 3D-CAD allmänt tillgängliga inom tillverkningsindustrin. I och med det påbörjades även en strävan efter effektiviseringsvinster genom att i större utsträckning utveckla virtuella prototyper istället för fysiska dito, en trend som alltjämt fortgår. Det finns dock aspekter av produktutvecklingsprocessen som blir lidande då den fysiska representationen av en produkt under utveckling uteblir. Således finns det gränser för i hur stor utsträckning digitala modeller kan bidra till effektivisering av produktutvecklingsprocessen. Den här avhandlingen argumenterar istället för en kombination av virtuella och fysiska representationer som en möjlig väg till ytterligare effektivitetsvinster.

I avhandlingen introduceras begreppet lågkostnadsdemonstrator. Genom att kombinera och studera fyra olika teoriområden - produktutvecklingsmetodik, prototypframtagning, datorstödd konstruktion samt pedagogisk teori – identifieras denna typ av demonstratorer som möjliga medel för att nå ytterligare effektivitetsvinster. Vidare visar sig lågkostnadsdemonstratorer särskilt användbara då produktutvecklingsprocessen innefattar ny och obekant teknologi. Lågkostnadsdemonstratorer kan potentiellt agera katalysator för kreativitet och innovation i datorintensiva utvecklingsmiljöer.

Till grund för utvärdering och validering av begreppet  lågkostnadsdemonstratorer ligger flera kurser i grundutbildningen vid Linköpings universitet.
