Concept Solution Generation for Product Innovation under User Fuzzy Semantic Requirements

According to the classification of user requirements in Kano model, theory of technology evolution was adopted to determine the future evolution route of product and predict possible structure state for the future technolo- gy, in order to mine the user's potential requirements. In view of the fuzzy and uncertainty of users' potential requir- ements, the fuzzy semantic model was adopted to describe the qualitative user requirements in order to standardly form the user requirements concept sets with functional attributes in different requirement categories, so as to guide the designers to create the innovative solutions along the right direction and then achieve the product rapid innovatio- n design. Taking the Pulse-Jet bag filter as an example, the case analysis shows that this method can effectively be applied to obtain new product innovation concept solution, and provide theoretical support for the mapping between subsequent innovation concept solutions and innovation function solutions and innovation structure solutions, and also provide the model architecture for innovation droved new product digital prototype design.
