Process design is often associated with the compromises of conflicting process parameters, which means a rising cost and a loss of quality. Innovation in process system can create great value. The rapid development of technology and commercial environment suggests that innovative process design needs the support of a systematic innovation strategy. The strategy combining inventive tools is proposed to support process innovation. Firstly, analyze the process system according to constraints, and employ Quality Function Deployment (QFD) to obtain process requirements. In this way, the conflicts of process system can be found accurately, then analyze these conflicts comprehensively, and creatively solve these process problems with the help of the Russian Theory of Inventive Problem Solving (TRIZ), and acquire more feasible solutions or inspiration through the proposed approach. After that, use Analytic Hierarchy Process (AHP) to select the best feasible alternative under multiple evaluating standards. In this approach, both the efficiency and maneuverability of applying Inventive tools to solve process problems are improved. Finally, the performance of the proposed strategy is illustrated and validated by the example of grinding process system.
