认知差异下的产品造型意象熵评价研究

Research on the entropy evaluation of product styling image under the cognitive difference

针对产品造型意象中的认知差异,提出了应用熵理论进行评价的新方法。确定研究样本和目标意象,进行产品感性意象调查;分别构建基于用户、设计师和工程师的意象认知空间,分析三者的意象认知差异;综合意象认知权重,建立满足三者情感需求的复合意象认知空间;利用熵理论构建以复合意象认知空间为核心的产品造型意象评价模型,指导产品典型案例库的选取。以水瓶造型意象熵评价为例建立的典型案例库可有效指导产品造型设计。

Aimed at the cognitive differences in product styling image, a new evaluation method was presented using the entropy theory. The product samples and the target image were determined then perceptual image investigation was carried out.Meanwhile, three image cognitive spaces were built for users, designers and engineers, the cognitive differences between them were analyzed, and a composite image cognitive space based on their emotional needs was constructed in view of cognitive weights. Taking the composite image cognitive space as core, an evaluation model of product styling image was presented using entropy theory, it could aid to select the representative product samples. Taking the image entropy evaluation of the water bottle styling as example, a typical database was built to effectively guide product styling design.
