In this paper, searching technology of product information based on knowledge was researched. On the aspect of cognition, we researched the relation between user\'s cognition and designer\'s cognition, explored the knowledge flow in the process of product development, set up a matching model between user\'s knowledge and designer\'s knowledge, brought forward a modeling method based on users\' cognition, and set up a measurable model of product feature; coded and decoded product form element, set up a computer aided product form design system and image evaluating system based on the result of measurement. Accordingly, the product style and product image were systematically discussed, the recognition space of product style and image was constructed, the factors that affect product style and image were put forwards and analyzed, and the relation between product image and form elements was tested by experiments. Furthermore, the product automatic recognition technologies were discussed.And then, with the media of concept model and the kernel of parameter technology, a mathematic model that describing product layout design by constraints and rules was presented. Furthermore, a product design integration system based on imagery thinking including product fonii base system based on imagery thinking, product form design system based on imagery thinking and product form intelligent design system based on space layout were set up, which tested the system and provided a new way for product innovative design.

本文以产品特征描述目标对象——产品，研究一种基于知识的产品信息检索技术，在对产品的认知方面，研究了用户认知和设计师认知之间的关系，研究了产品开发过程中的知识流传递过程，建立了用户知识和设计知识之间的匹配模型，提出了一种基于用户知识的产品建模方法，它不但提取了产品的特征，还建立了产品特征量化模型，从而实现了产品知识的量化描述；对产品造型元素进行分解和编码，利用实验量化结果构造计算机辅助产品形状设计系统和心象评价系统；使用量表分析造型元素的心象尺度，构造输入、输出系统，建立了产品设计知识库咨询系统，可以方便用户和设计师来导入或查询产品设计方案；实现了对产品造型心象的分类知识库系统，便于设计师存储或查询，辅助设计师进行产品创新设计；通过实验量化了产品造型参数和产品心象参数之间的关系，并在此基础上建立了基于心象的产品形状设计系统，为产品空间布局方案智能生成系统奠定基础；在基于知识库的基础上建立了产品空间布局方案智能生成系统，通过更改概念产品造型参数，实现了产品设计方案的智能生成，使系列化的设计工作变得十分方便；将产品的心象运用到实际设计过程中，能够引导流行趋势，创造出产品无形的设计价值。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
