Individualized and accurate eco-design knowledge push for designers: a CAD-based feedback knowledge push method for the eco-design

Abstract

In the conceptual design phase of eco-products, the evaluation of products eco-design is often considered by designers after determining the design scheme. In order to improve the eco-design efficiency, a CAD-based feedback knowledge push method was proposed to meet the designer’s eco-design knowledge requirements. Combine with the designer knowledge background, classified eco-design knowledge, and decomposed design tasks, eco-design knowledge requirements of designers can be obtained. Based on the cosine similarity algorithm of the knowledge vector space model (VSM), the knowledge requirements of the designer and the knowledge in the knowledge database are matched, and the eco-knowledge is actively pushed to the designer. The feedback and evaluation of designers on the initial push of knowledge was recorded by the system. When the designer is assigned relevant eco-design tasks again, the system conducts secondary filtering of eco-design knowledge through previous feedback records and pushes the filtered knowledge to designers, so as to achieve accurate feedback knowledge push. A CAD-based eco-design knowledge push prototype system for automotive products is developed. The eco-design of the front-end module of the automotive is used as an example to verify the effectiveness of the above method.

Digital Eco-Design and Life Cycle Assessment—Key Elements in a Circular Economy: A Case Study of a Conventional Desk

“…The authors concluded that to avoid a slowdown of this transition, it is necessary for both people and companies to internalise the competitive advantages and business benefits that a circular economy can bring. Zhang et al [24] proposed a knowledge feedback methodology based on CAD systems to make it easier for designers to find prior eco-design knowledge that meets the requirements of the new designs they are developing. In this way, when a designer is assigned a new eco-design area, an algorithm shows similar solutions to the problem posed and facilitates adapting the solution to the new design while providing further feedback into the system.…”

Connector-link-part-based disassembly sequence planning

“…In recent years, the increasing importance of environmental protection issues has focused attention on DSP. If scientific evaluation methods can be proposed, they will facilitate the objective evaluation of CE (Ghandi and Masehian, 2015; O’Shea et al, 1998; Zhang et al, 2021).…”
