Abstract: Fuzzy Front End (FFE) was selected as the beginning of the product innovation stage and innovative ideas could improve the success rate of product innovation. With FFE as driving force of innovation, the gap between product performance and customer needs was analyzed by applying the conflict resolution principles of TRIZ and then innovative ideas based on market demand were determined. The ideal product level and customer satisfaction were improved by architectural innovation; The application of the law of demand evolution and the law technical of evolution were applied to determine the future evolution of demand for the product and its corresponding technology. Relevant technology of the product was upgraded through theory innovation so as to improve its response to future market demands. Based on product architectural innovation and the principles innovation, by integrating CAI Knowledge Base, systematic FFE-driven product innovation process model was established from the innovative ideas to the conceptual design, which helped the designers to improve independent innovation and innovation success rate. This innovative model was used in the innovative design of the belt conveyor and a new type of magnetic cushion belt conveyor technology was also developed.
