The purpose of this paper is to present a creative product design process (PDP) based on customer's cognitive response (CCR) to product sign. Based on the user-product interaction model, combining with symbolic information-processing (SIP) and situativity (SIT) approaches, our work explored the process and methods of CCR, and then outlined the creative product design process model after analyzing...
The purpose of this paper is to present systemic unexpected users' needs discovery (UUND) methods based on semantic networks (SN). Based on the nature of unexpected user's needs and SN, combining with hierarchical semantic network model, feature comparison model of semantic memory and spreading activation theory of semantic network, this paper outlined and formalized the basic semantic network unit...
Classical QFD can not analyze the uncertainty involved thoroughly. To deal with the problem, a new method based on cloud model was presented. The numerical character and certainty degree of the cloud drops were analyzed through the forward cloud generator, backward cloud generator and cloud expected curve. The importance of the customer demand and the engineering measures were described from both...
