Study and Implementation on Computer Aided Innovation System Based on TRIZ

The aim of Computer Aided Innovation (CAI) is to support the engineer’s problem solving process with current design method and knowledge base. TRIZ is developed based on the patents analysis within the cross domain in the world and it is used in innovation design widely. Conflict Matrix, Effect, Standard Solution and Separate Principle are the key TRIZ tools used to resolve the inventive problems. And they can also be used for knowledge representation in the design system. As a Computer Aided Innovation System, Innovation Engine is developed and instructed. The effect of TRIZ methodology and CAI system can be proved with the case analysis of the cavity shape design of the rotor channel in the vertical shaft impact crusher. With limited power of electrical motor, there is a technical conflict in a vertical shaft impact crusher when requirement of improving break ratio of the stone materials. With the recommended principle (Curvature), the conception of a channel with a curvilinear shape can be gotten.
