Algorithm for inventive problem solving(ARIZ)is a specialized method in the theory of invention problem solving(TRIZ)for solving complex problems.It integrates multiple TRIZ methods and tools to set a set of systematic problem thinking and solution process from problem analysis to solution selection.At present,the automobile rear seat structure are metal materials,the overall quality is large,the forming and assembly process is complex,in order to reduce weight,reduce tooling,put forward the concept of plastic instead of steel,the rear seat use plastic backrest,but the the performance of plastic materials have limitations,it is difficult to pass the requirements of regulations,causing prone to fragmentation problems.Use ARIZ and knowledge base for creative thinking and solution,gradually implement the 9 key steps of ARIZ according to the process,analyze the problem model,and finally realize the innovative research of replacing steel with plastic by the back panel is realized.
