Abstract
The authors present a Conceptual Design Support System(CDSS). To develop creative products for a short period of time, it is indispensable to support a designer by offering a series of forms. Although TRIZ provides the technique of supporting a way of thinking, it is not enough to support. Because an idea is not produced if a designer's insight is insufficient. In order to solve it, the system has a view of QFD and USIT in addition to TRIZ. Using a system which combines these techniques, it will be possible to clarify problems and to raise designer's insight much more.
