Closed loop design method based on TRIZ & FBS

The relationship between TRIZ theory and FBS theory is expounded.Besides,by combining these two theories,this paper presents a new approach about innovation design on products.To be specific,it estimates products' potential to evolve with "S curve"at first.Secondly,based on the research of patents,the evolutionary directions of products can be predicted and summarized by"Evolution potential figure"and"Evolution mode"of TRIZ theory,then based on the FBS theory and evolutionary directions found at last step,designers can get a plant of "function-behavior"solutions by divergent thinking.With those information,they can find the optimal solution by"Contradictory matrix"of TRIZ finally,thus the invention design are completed.In the end,this paper verified the feasibility of this new method by completing an invention design on rubbing machine.
