Key Technologies for Sustainable Design Based on Patent Knowledge Mining
Abstract With the rapid development of global economy, sustainable problems have aroused widespread concern by all countries in the world. Sustainable design is a systematic design method to develop the sustainable products or form the solutions to sustainable problems to adapt the sustainable development. This article was a study of key technology for sustainable design through the patent knowledge mining, aiming to provide technical support and process model to the transformation from traditional products to sustainable products. On the one hand, sustainable design criteria for design goal, life cycle and design strategy are extracted and established through the patent knowledge mining and the product sustainable requirements. On the other hand, the laws of function organization and improvement are extracted by patent knowledge mining and dynamic analysis of function evolution. Then the process model of sustainable product function innovation was put forward by integrating sustainable design criteria, functional evolution laws and TRIZ into traditional function design. Finally, the buckle ring machine was taken as an example to validate the effectiveness of the model.
