Abstract
In conceptual design phase, if designers are much more conscious of design objectives, they won't come up with various ideas about new product. On the other hand, using brainstorming allow to get various ideas, but to get a lot of unavailable ideas together. In this study, we propose the method that supports generating various and effective ideas in conceptual design. In the last our study, we have proposed conceptual design support method using Data Envelopment Analysis. The last method?s approach is using several evaluation values to fill the gap of palate frontier. But it was too difficult for subjects to use this approach in the experiment. Proposed method in this paper supplies key words. These key words are made of calculated component values using made nonlinear mathematical model of relation between component and evaluation of idea with Neural Network. We confirm that the method is useful in terms of simplicity of generating various and effective ideas.
