针对绿色设计中可拆卸设计问题，提出运用TRIZ冲突解决原理和TRIZ物质-场分析原理进行产品零部件间连接结构的可拆卸设计。通过构建连接结构可拆卸属性与新TRIZ冲突矩阵48个工程参数之间的关联表，并建立连接结构的TRIZ物质-场模型，分别给出了利用TRIZ冲突解决原理和TRIZ物质-场分析原理进行可拆卸设计的两种方法，以提高产品零部件的可拆卸性能。设计实例证明了方法的可行性。

英文摘要：

For solving the problems of DFD in green design,TRIZ methods were used to provide innovative ideas to improve the disassembly properties of joint structure between product parts. Two DFD methods were proposed through constructing an associated table between 48 engineering parameters in new TRIZ conflict matrix and disassembly attributes of joint structure, and through establishing TRIZ substance--field model of joint structure, the disassembly property of product can be improved by the combination of TRIZ principle of conflict resolution and substance--field analysis. At last,a design case proves the feasibility of the proposed methods.
