基于产品基因的无人探测小车概念设计方法

A Genetics-Based Conceptual Design Methodology of Unmanned Probe Cars

为解决概念设计阶段由于设计约束和关键信息模糊不全,导致设计者在进行设计时具有一定的盲目性,且设计出的方案可行性难以保证的问题,提出一种基于产品基因的概念设计方法,创建了概念设计过程模型.在此基础上,提出了产品基因的概念和结构及一种基于功能元的产品基因编码方法.以无人探测小车为例对基于产品基因的概念设计方法进行了说明.结果表明该方法能够使影响概念设计的关键产品信息明确化,降低设计的盲目性,从而提高设计方案的可行性和设计效率.

In order to solve the problem of fuzzy design constraints and incompleteness of key information in conceptual design stage,a conceptual design method based on product genes was proposed,overcoming some blindness in design process and improving the feasibility of designed schemes. Firstly,a conceptual design process model was established. Based on this,a new definition and composition of product genes was put forward. Then,a product gene coding method based on functional elements was proposed. Finally,a genetics-based conceptual design method was described with an unmanned probe car as an example. The results show that this method can clarify the key information of products in the conceptual design process,and reduce the blindness of design so as to improve the feasibility of design schemes and the design efficiency.
