Creative and inventive design support system: Systematic approach and evaluation using quality engineering

In recent years, designers have been required to design creative products in a short period of time. In addition, the problem definition and conceptual design phases significantly change the direction of product attraction. These phases depend heavily on the creativity of the designer or development team and dictate the quality of the product concept. In this situation, it is difficult for designers to quickly create a host of solutions without some kind of support for their creative thinking processes. To overcome this difficulty, we used a systematic approach to develop the thinking process of the Creative and inventive Design Support System (CDSS). Moreover, its validity was examined by using the design of experiments (DOE) and the Taguchi method (TM). These evaluation results confirmed that creative design solutions can be explored using the support of the CDSS thinking process.
