Abstract
In conceptual design phase, According paying attention to specific design objectives, designers sometimes avoid to get various ideas about new product. On the other hand, using brainstorming allows to get various ideas, but it causes a problem to obtain a lot of unavailable ideas together. In this study, to support generating various and effective ideas in conceptual design, we propose a conceptual design support method applying Data Envelopment Analysis and TRIZ. We proposed the method using several evaluation values to fill the gap of pareto frontier and creating hierarchy graphs. In this study, we propose the method using TRIZ at the Brain Storming stage in addition to the our proposed method. Various information is given to the designer from hierarchy relation graphically and TRIZ when they conceive new ideas. We verified which technique is effective to obtain new ideas with high evaluation by comparing these two methods. The result shows that the proposed method using TRIZ is more efficient than the other way not using TRIZ.
