Idea Generation for Fuzzy Front End Using TRIZ and TOC

Mini-problems are a kind of problems, which should be solved for incremental innovation for existing products. The major method to solve them is to find the contradictions, technical or physical, existed in a product, and to solve them. The current reality tree (CRT) and conflict resolution diagram (CRD) of theory of constraints (TOC) are good at finding contradictions. Theory of inventive problem solving (TRIZ) is applicable for solving them. It is reasonable to integrate TOC and TRIZ to form a process from finding them to solving them. It is core function to generate ideas for the solving contradictions for the fuzzy front end. A four-step process model for that function of FFE is developed
