The model building research of product innovation design quality based on QFD and KANO

The original of product design innovation move from driving by technology innovation to customer needs, technical innovation and service pattern's CTS driving(Customer Needs, Technological Innovation and Service). The previous theory of product design did not suit to new environmental factor and also did not reflect and synthesize other factor for product design. QFD is a system method which transform customer needs to definite measure for design product or design service. The theory of KANO provide five types of customer needs, with analyzing the needs of customer in order to provide design direction for product design. Paper research with the main line of QFD, through HOQ technique of QFD, delivering customer needs to designer, utilizing KANO model to identify various kinds of needs, through the transform of importance degree, sequencing importance degree of AHP for customer needs, combining above all so that clarify direct of design in order to ensure the quality of design.
