A Knowledge Push Approach to Support the Green Concept Design of Products

With the development of the manufacturing industry, environmental problems have become more and more serious. At present, green design is playing an increasingly important role in product design and manufacturing. How to combine traditional conceptual design methods with green designs to realize green conceptual design is of great practical significance. In order to realize the green concept design of a product and to allow the conceptual design scheme to meet the functional requirements and green performance requirements of the product at the same time, this study introduces the knowledge push process and the green filter process into product concept design. The knowledge of invention principles is retrieved by establishing the knowledge space of invention principles, by calculating the word segmentation based on the CRF (conditional random field), and calculating the word similarity using a thesaurus. This is performed in order to realize the transformation from product function requirements to invention principle knowledge. Then, by studying the relationship among the environmental efficiency factors, green design attributes, engineering technical parameters, and invention principles, the correlation mapping table for green design attributes and invention principles is established. Thus, the green filter is applied to the pushed knowledge according to the green performance requirements, so that the final push results after filtering can meet the functional and green performance requirements of the product. In the last section of this paper, a green concept design for cutting the fluid supply system in an enterprise is presented as an example to verify and analyse the proposed method.
