概念设计方案生成的可计算方法

概念设计阶段分层映射过程模型的建立与应用增强了功能推理与求解过程的发散性与创新性,但却给生成候选概念设计方案带来了困难,概念设计方案的生成缺乏有效的可计算方法。文章采用相关矩阵描述概念设计过程的信息进化过程,并由此提出基于功能—效应—原理模型的概念设计方案生成算法,该算法通过矩阵运算对解空间进行优化,获得嵌套矩阵,对嵌套矩阵进行搜索从而生成候选概念设计方案。以手提式钉枪的概念设计为例对算法进行了验证。

Computational Method for Conceptual Design Plan Generation

The set-up and application of hierarchy-mapping process models for conceptual design can significantly enhance the divergence and creativity of the function inference and solving process. However, it makes the conceptual solutions hard to be generated because of the lack of a computational methodology. The paper adopted the correlation matrix to describe the design information and presented conceptual design plan generation algorithm based on function effect-principle modle. The method firstly employs matrix-based algorithm to optimize the solution space to obtain nesting matrix, then search nesting matrix to generate candidate conceptual design plan. The design of "nail gun" is used to verify the proposed algorithm.
