理性和感性设计方法的结合是产品造型设计中的难点和关键。本文运用现代科学方法对产品造型设计中理性与感性的方法进行解读,给出它们的形式化定义,并通过建立转换函数得出理性与感性结合的算法,最后以火炬项目予以说明。 The combination of rational and sensual design methods is a difficult and critical product design. This paper uses the modern scientific method to interpret the rationality and perceptual method of product design, gives their formal definitions and constructs the conversion function to get the combination of rationality and sensibility. At last, it explains the torch project.
