摘　　要：阐述了TRIZ理论的概念,其核心思想是对矛盾问题的完全解决,获得最终的理想解。介绍了40条创新原理和39个通用工程参数及矛盾矩阵,并介绍了利用TRIZ理论解决产品创新设计问题的流程。用此理论对某载货车的板簧后固定支架及板簧吊耳进行轻量化设计,以其实际问题抽象为工程技术参数,并确定了优化的参数与恶化的参数以及二者之间的矛盾,应用矛盾矩阵找到解决问题的发明原理。通过拓扑优化和材料的改变,获得了理想的结果,并用有限元法定量分析和最终理想解的四个重要特征来定性分析,说明优化结果的合理性。The concept of TRIZ theory was expounded, which core theory was to completely solve the contradiction problem and achieve the finally ideal solution. The 40 innovation elements, 39 general engineering parameters and contradiction matrix was introduced , and the process of solving the innovation and design problem used the TRIZ theory. A truck suspension rear bracket and shackle was lightweight designed by the theory. Abstracted the engineering technique parameters from the actual questions, obtained the optimized and the worsen parameters and the confliction between the each other, and then, found the invent principle of the problem solving by the used of the contradiction matrix. The optimized result was reasonable to the ideal result, which was obtained by the topology optimization and the material change, the quantitative analysis of FEA and the qualitative analysis of the four important characters of the final ideal result.
