An innovative design methodology KKBDCA for affective product development

Abstract

This study proposes an innovative design scheme, called KKBDCA (Kano model, Kansei engineering, Base information, Design developing, Creativity thinking, and quality Assurance) for developing affective products. Firstly, a modified Kano model is proposed to link the customer's overall satisfaction and customer's partial preferences. Secondly, the KE together with appropriate quantification theory is used to establish the mapping relationship between design elements and customers' preferences. Then, a prototype of product with high customer satisfaction index (CSI) is selected from the product database as design reference. Thirdly, through the operation of BDCA design procedure, a new style of product is performed. Finally, verification is done to the new designed product and a satisfying evaluation result is obtained. The proposed integrated scheme may be used as a design methodology to explore new product style that satisfies customers' needs in overall aspects. © 2013 Kun-Chieh Wang and Fang-Rong Ju.
