Abstract: The efficiency reinforcement technologies of sealing is important for improving sealing’s reliability and effectivity which result in zero leakage. Technology evolution of TRIZ can be used to forecast the future technology in products. These future technologies can guide a designer along the right direction of developing a new product. In this paper, the efficiency-reinforcement principle of hydrodynamic reciprocating sealing is discussed, technology evolution of TRIZ is integrated with the efficiency reinforcement design of hydrodynamic reciprocating sealing element to predict its future structure state. A new cross section shape of reciprocating sealing element corresponding to the predicted structure state is presented. The computational model of the new reciprocating seal element is established with ANSYS, and its stress, strain and pressure distribution are also analyzed. The results demonstrated that the presented seal elemente outperforms the old O-ring seal in efficiency reinforcement capacity.

Abstract: Many solution tools TRIZ provided, such as innovative principles, technology evolution, have been widely used for product innovative design in last decade. The key using TRIZ to improve design is the correct definition and solving of technical problems. However, it’s difficult for engineers to discover the inherent problems of product, especially for complex engineering systems. Therefore, this paper proposes a whole process model for product systematical innovation design, whose objective is to obtain ideal solution and whose technical method is to analyze and solve conflicts. This model integrates the definition, analysis of problems from top to bottom, with the resolving of problems from bottom to top, and will contribute to a systematic and operable process for problems definition, analysis, resolving. A practical application of this work is also presented.
