Abstract

In the stage of a conceptual design, designers often stimulate and influence each other, and they must conceive a completely new idea and the outstanding idea. However, as a design problem, it is dependent on a designer's experience and intuition. Furthermore, the suggestion of an idea is sometimes plentifully performed by two or more persons, sharing of mutual knowledge or information for a smooth communication. Therefore, it is necessary to establish the reasonable design method to derive excellent idea, in this study, the new design approach which combined two design methods of an axiomatic design theory and TRIZ is proposed, the validity of a design method is confirmed. The axiomatic design theory clarifies the process in a design TRIZ offers the solution of a design which a designer didn't know. By combining these advantages, we will proposed a new method. The experiment using the proposed methods, technique nothing, TRIZ, the axiomatic design theory, and the TRIZ+ axiomatic design theory. And, it is verified what kind of difference the number of ideas or quality. As a result, TRIZ was able to conceive many ideas, but quality is inferior to other design methods. The axiomatic design theory could conceive the high quality idea, but a number of ideas are inferior to other design methods. Although the TRIZ+ axiomatic design theory had few ideas, the highest quality idea was able to be conceived.
