利用发明问题解决理论(Theory of innovation problem solving,TRIZ)与公理设计(Axiomatic design,AD)的集成技术,建立了基于两者的概念设计过程模型。首先,在约束条件下,运用TRIZ和AD来完成产品功能-结构的映射,构造并求解出其原始的设计矩阵;然后,基于公理化设计理论判断原始矩阵是否耦合,若不是耦合矩阵则产生创新方案,若是耦合矩阵,则利用TRIZ工具集将实际问题转化为TRIZ标准参数,以达到消除耦合的目的。为了验证海草夹苗机械手设计方案的可行性,利用ADAMS将优选的方案进行虚拟仿真。最后,利用加权线性响应面法,对夹苗机械手关键零部件进行可靠性分析,以求出相应的可靠度值,该值验证了设计结果的可靠性。

A conceptual design model is established by integrating theory of innovation problem solving (TRIZ) and axiomatic design (AD) to solve problems for product innovation. Firstly, under the constraints, TRIZ and AD are applied to construct the mapping relation of function-structure, and then establish and resolve the original design matrix. Secondly, judge whether the original matrix is coupled or not with axiomatic design theory, if not, the innovation scheme is generated. If it is a coupling matrix, then TRIZ toolbox turn the real problem into standard engineering parameters to achieve the purpose of eliminating coupling. Then, feasibility of the optimal scheme is verified to make virtual simulation using ADAMS on seaweed planter manipulator. Above all, the reliability about the key parts of the seaweed planter manipulator is analyzed using weighted linear response surface method, and the size of the corresponding reliability is obtained, then the reliability is verified for the design result.
