Research on inventive problem solving process model based on AHP/TRIZ

According to fuzzy problems in innovation schemes selecting process of applying the theory of inventive problem solving (TRIZ) in product innovative design, the analytical hierarchy process (AHP) is integrated with the TRIZ method, an inventive problem solving process model and corresponding algorithm based on AHP/TRIZ are presented by the research of fuzzy theory. In this model, firstly designer’s demand feature information is extracted and decomposed into technical contradictions, and the contradiction solving matrix of TRIZ produces innovation schemes set, then AHP gives a comprehensive evaluation of all the innovation schemes in the set and chooses the best one by evaluation, and finally subjects the innovative design of an engineering scheme with the inventive problem solving process model based on AHP/TRIZ and indicates correctness and superiority.
