目的 研究面向时序关系的装备产品造型设计识别要素。方法 从产品识别的基础理论研究出发， 采用造型Metaphor的方法并结合Sato提出的DIS（Design Information Structure）， 对装备产品时序性识别要素进行获取与表达， 并分析了时序性产品识别要素类型与适应性， 以及基于时序关系的产品识别要素的关键特征演变。结论 提出了基于时序性产品识别要素的设计创新方法， 研究最终通过项目组承担的中联重科汽车起重机设计项目， 对设计创新方法进行了验证。

To study the product identity factors of equipment product form design based on sequential relationship. Based on the basic theory of product identity， metaphor and DIS（Design Information Structure）are used to extract the sequential product identity factors of equipment. The types of sequential product identity factors and its adaptability are studied. Then the extraction method， key features of sequential product identity factors is studied. An innovation method based on sequential product identity factors is proposed， which is further verified in the Zoomlion equipment styling project.
