The Outline of the Style and Constructed Process of the Categories in Product Design

本研究通过对汽车、摩托车、手机等产品的类型化及其结构的研究，提炼出产品的基本范畴，考察其在时间上的创造和变化过程，从而决定了社会种族和技术进步对相互“力量”的调节形成的过程。在产品品类的不变化力中，有社会背景的问题，也有产品领域特征的影响，包括历史和价值观念的影响；在每一种产品品类的变化中，都有“派生”、“细分”、“同质”和“不变”。“通用化”可以强化典型性，以更清晰的形象渗透到产品中。未来需要解决的问题是对形式的详细信息进行分析。因此，对部分与类别之间的参与情况进行调查，并估计贡献的大小，是一个课题。

This study takes notice of a category of products made by typifying and the structure, extracts the basic category of products, investigates the creation in time siries and the process in the change by the case study of "car", "motor bicycle", and "portable telephone".As a result, the change of the category of products decides the process of the formation for adjustment of mutual "power" by a social race and a technological improvement. And in the power for unchanging of the category of products, there is the probrem in social background and the influence by the character of the field of products including the history and the sense of values.In the change in each category of products, there are "derivation", "subdivision", "homogeneousness" and "changeless". The "universalization" can reinforce the typifying, can permeate products as more clear image.The problem to be solved in the future is analysis focus on the detailed information of form. Therefore, it is the subject that the investigation of participation between the parts and the categories, and the estimation of size of the contribution.
