集成TRIZ的产品生态设计方法研究

Research on Product Ecological Design Method Integrating TRIZ

针对产品生态设计过程中的创新问题,提出一种集成发明问题解决理论(Theory of inventive problem solving,TRIZ)的产品生态设计方法。该方法结合案例库和专利库,利用生态效率要素和TRIZ工程参数关联表构建矛盾矩阵,运用TRIZ工具进行求解,并对生成的多个备选方案进行评价,确定最优解。同时研究案例的检索方法以提高检索有效性,分析技术进化趋势以启发设计工程师设计灵感,构建计算机辅助设计系统以弥补人工不足,这些方法都能有效提高生态设计的效率和成功率。通过差速器摩擦片的设计案例验证了该方法的有效性。

A product ecological design method integrating theory of inventive problem solving（TRIZ） is proposed to resolve the ecological innovation issues involving in the process of product design.Combining case base and patent base,this method utilizes ecology efficiency factors and TRIZ engineering parameter correlating table to establish contradiction matrix,which will be solved by TRIZ tools.It also evaluates the available solutions deduced to select the optimum.Detailed methods are stated to significantly promote the efficiency and success rate of ecology design in the sense that case searching is studied and refined to improve the effectiveness,the trend of technique evolution is analyzed to provide design engineer great inspiration,and CAD system is constructed to offset the drawback of artificialness.A case study of differential friction disk design is introduced to validate this method.
