为了理解工业设计领域中设计活动的特征,提出利用信息框架概念划分设计认知策略的方法.基于系统输入、输出原理,采用信息要求的实验方法,对产品设计前期形成的信息内容范畴、数量和草图方案进行分析,建立包含5种设计信息类型的框架,将设计师处理设计问题的信息加工方式分为信息框架、非信息框架和准信息框架3种.通过比较这3种认知策略各自的特征,深入分析创新活动在设计信息加工方面的一般规律.该划分方法减少了设计活动分类、时间、设计对象类型因素对区分认知策略的影响,更为普遍地反映了认知策略的特征,并在设计教育实践中得到了应用和验证.
A classifying method of design strategies based on information frameworks was developed to understand the characteristics of cognitive activities in industrial designs. The information content, information amount and sketches in the design prophase were analyzed by the system input&output theory and the information requirement experiment method, and a framework which including five kinds of design information was built. Then the information processing methods in the designing process were categorized into three kinds: information framework, non-information framework and semi-information framework. The information processing rule of innovation activities could be analyzed by comparing these cognition strategies' characteristics. This classification method reflects the cognition strategies more generally, thus can reduce the influence of activities classing, time and design objects. The research result was applied and tested in the design education and practice.
