Abstract: To help designers obtain valuable innovation opportunities in the fuzzy front end stage of product development,a scenario based approach was proposed.The method clarified the relationship between product participation scenarios and product innovation process,and the product innovation opportunities were found from the perspective of uncertain future scenario conditions and evolution principles.Taking the typical practical scenario of prototype product as the initial scene,different scenario operation strategies were applied to the initial core scenario elements,user related elements and environment related elements in the scenario conditions to explore the possible new scenario elements and features in the future,and a process of reorganizing new future scenario conditions was proposed,then the feature requirements of product for integrating into different scenario conditions were found.Meanwhile,the discovery process of evolution principle supporting scenario expected evolution was proposed,and then the function characteristics of product to realize this principle were found as innovation opportunities.Finally,the proposed method was introduced to the innovation process of vacuum cleaner equipment,and a variety of product innovation opportunities were identified.
