A Multi-perspective and Multi-level Based Approach to Organize and Represent Inventive Knowledge

摘要

Through analyzing the solving mechanism of product inventive design problem based on TRIZ theory, we propose in this paper a multi-perspective and multi-level knowledge organization model, so as to fill the "GAP" between the general solution and the particular solution in the process of solving inventive problems. We labeled here design knowledge by five attributes, i.e., TRIZ, function, behavior-flow, effect, and domain, each of which includes respectively three levels that are conceptual level, semantic level and factual resource level. Thereby, a multi-perspective and multi-level local knowledge base is established. Besides, we put forward also a card-type knowledge representation template, which divides the traditional cases, patents and other knowledge into several independent parts, and each of them can be displayed and pushed to designers in form of cards. Thus, it's conductive to stimulate designers' analogy and association. One multi-perspective and multilevel knowledge organization based inventive problem solving model is conclusively established, which supports analysis and problem-solving in different perspectives and at different levels. A conceptual design of an ultrasonic washing machine is illustrated at the end as an implemented example for this proposed model.
