Abstract: Disruptive innovation is a product innovation technology that breaks the mindset,which is helpful for the new and old enterprises to realize the innovation of technology,and improve the core competitiveness of enterprises.In order to reduce the threshold of disruptive innovation,integrate the technology evolution theory and innovative tools of TRIZ and scenario decomposition method based on the disruptive innovation theory,creating the model of disruptive innovation based on the scenario decomposition method and TRIZ,the efficiency and quality of product technology maturity prediction and the innovation solution obtained are improved,and the pertinence of the key problem analysis is enhanced,the rationality and practicability of the model are verified by the example of the disruptive innovation design of refrigerator.

Key words: disruptive innovation, TRIZ, technology evolution, innovative tools, scenario decomposition method
