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.
