中文摘要：

产品设计DNA是基因工程的思想运用于工业设计领域所产生的新概念,涉及多个知识领域,旨在赋予产品独特的形态及风格意象以塑造品牌。文中系统地总结了国内外产品设计DNA研究的现状与进展,重点介绍了表达结构、应用研究进展、关键技术及现有研究之不足。最后提出产品设计DNA研究的热点与趋势为：揭示全生命周期下的产品设计DNA生成与衍化规律;探索用户对于产品设计DNA的认知机制;实现产品设计DNA推理与生产环节的衔接。

英文摘要：

A new idea named design DNA appears when genetic engineering is applied to industrial design,which is related with multiple knowledge areas. The aim of design DNA is to give products unique shapes,styles and imagery in order to make brand image. The current state and developments were summarized at home and abroad on design DNA in which the expression construction, application, key technologies and deficiency were focused on.Finally,future hotspots and trends are proposed, namely, to reveal the deriving and generation law of design DNA during the whole life cycle,to explore users′ cognitive mechanism on design DNA and to connect design DNA reasoning with production process.
