基于产品系谱的概念结构多方案设计方法

Pedigree Based Product Multi-Scheme Conceptual Design

将生命现象中的系谱理论引入产品概念结构设计中,提出了基于产品系谱的概念结构多方案设计方法。根据产品从定量到定性的进化逻辑,得出不同概念结构之间的结构联系,表达为进化谱系,建立了产品系谱的描述模型,为实现概念设计的智能化提供了统一的功能同构模型;根据产品从定性到定量的演化逻辑,提出了基于系谱的产品结构设计策略,通过系谱单元之间的关系网络,可以得到多个变异设计方案,为产品的创新设计提供支持。最后,设计实例验证了所提出的基于系谱的概念结构多方案设计方法在产品设计中的成功应用。

By applying pedigree into product conceptual structure design,an evolutionary conceptual design approach is set forth to make full use of creative and innovative intelligence of living systems for design automation.According to the evolutional logic of quantities to quality,the relationship between different conceptual structures is deduced and ordered,then is expressed as product pedigree.The classification description model of product pedigree is established,which can be used as unified functionally isomorphic model during the intelligent conceptual design process.On the other hand,according to the evolutional logic of quality to quantities,pedigree based product evolutionary design strategy are given.Based on the relation network among pedigree units,multiple variation designing schemes can be obtained,which is a strong backbone to the innovative design process.Finally,design examples are used to demonstrate the successful application of the proposed pedigree based evolutionary method in the multi-scheme conceptual design of product.
