Reuse of principle solution elements in conceptual design: an information model for concepts in systematic design
2003 (English)Licentiate thesis, comprehensive summary (Other academic)
Product development is an important activity in engineering design, and much of the competitiveness in high-salary countries depends on the ability to develop innovative products with acceptable time to market.
The early phase of a systematic design process, namely conceptual design, during which the principle solution for a product is conceived, is of high importance for the later success of products. Available design support tools are mainly oriented towards embodiment design (e.g. volume modellers), and they are not effectively supporting conceptual design.
During conceptual design, creative steps and the modelling of function structures, principle solutions and concepts must be supported in order to reduce the high time need of systematic design methods.
Literature as well as existing research prototypes have been analysed to determine the state of the art in research regarding computer supported conceptual design. Design projects of master's degree engineering students, previously carried-out at the division, have been studied in order to gain insight into the needs and possibilities of supporting concept generation for various design tasks.
The work has resulted in a parametric information model that is able to describe concepts as choices of principle solution elements and their quantification by value choices. The model is operating on higher semantic level than e.g. document or model files by applying a constraint network that connects parameters of requirements, function structure, principle solutions and concepts. The model has been tailored towards easy exchangeability of principle solution elements by a division into different constraint types, of which internal constraints directly are reusable. The presented information model has been partly verified in a prototype implementation.
