目的为使产品原型设计契合消费者的感性认知与情感需求,对产品原型形态进行意象造型与形态耦合优化设计。方法首先,以产品原型理论为基础开展原型实验;其次,采用最小距离的NURBS曲线的形态混合算法对产品原型与意象原型进行融合均化;然后,应用频谱分析法量化产品形态特征,通过余弦相似度计算形态耦合度,并结合消费者意象评价值与造型偏好度分析形态耦合机制;最后,运用遗传算法建立优化设计系统对目标意象下的产品原型形态进行优化。结果实现目标意象下产品原型设计方案的耦合优化,获得契合消费者情感认知的细化形态。结论此方法可对产品意象原型进行合理有效的耦合优化,实现产品形态的细化设计。

The work aims to carry out the image styling and form coupling optimization design for the prototype form of the product, so as to make the product prototype design in line with the consumer's perceptual cognition and emotional needs. Firstly, the prototype experiment was carried out based on product prototype theory. Then, the form blending algo- rithm of NURBS curve with minimum distance was adopted to fuse and homogenize the product prototype and image prototype. Next, the spectrum analysis method was applied to quantify the form characteristics of the product. The form coupling degree was calculated by cosine similarity, and the form coupling mechanism was analyzed by combining con- sumer's image evaluation value and form preference degree. Finally, the genetic algorithm was used to establish an opti- mization design system to optimize the product prototype form under the target image. The coupling optimization of product prototype form design under the target image was realized, and the refined form of consumer emotion cognition was obtained. This method can optimize the product image prototype reasonably and effectively, and realize the detailed design of product form.
