The problem solving process and method of computer-aided innovation design platform Pro/Innovator are introduced. Taking accuracy for swing arm of oil cylinder manipulator as a case,according to Pro/Innovator and TRIZ innovation method theory,the smart little people method is used to build model for analyzing problem and setting goal,the function analysis,cutting pattern analysis and causal analysis are carried out for model. The problem is solved by using three groups of opposite technical contradictions as starting point,and seven solutions are formed by using innovation knowledge information base. The optimal solution is obtained by building evaluation model and analyzing value of solution. After verification,the optimal solution improves greatly accuracy of swing arm of manipulator,which plays a promotion role on continuous and automatic feeding of bearing grinder.
