Development for creative and inventive design support system (2nd Report, evaluation of creative and inventive thinking process using quality engineering)

In recent years, industrial designers are required to design creative products in a short period of time. Attractive product is changed significantly by requirement definition and conceptual design phases. The Quality of product concepts, which is result of these phases, depend heavily on the creativity of designers or development teams. It is difficult that a computer-aided system supports a creative and inventive thinking process, and searches a creative design solution. To overcome these difficulties, authors developed a systematic approach of the creative and inventive thinking process called Creative and inventive Design Support System (CDSS). In this paper, its validity is examined by using to the Design of Experiments (DOE) and the Taguchi Method. From these evaluation results, it is confirmed that creative design solutions can be searched by using the creative and inventive thinking process of CDSS.
