Ecodesigning with CAD Features : Analysis and Proposals

الملخص EN

The integration of environmental aspects in design frameworks has become a necessity for manufacturers to maintain their market position.

This is especially true in the Computer Aided Design (CAD) phase, which is the last phase in the design process.

At this stage, more than 80% of choices have been made.

However, the environmental impacts generated by the remaining choices are significant.

Features Technology (FT), the core of the CAD phase, is used to integrate environmental aspects.

This paper presents a literature review of different works based on FT to ecodesign products.

First, we present an overview of features in CAD systems.

Second, we present a critical review of works done on ecodesigning with features that we divide into two subsections: the first one concerns CAD-Life Cycle Assessment (LCA) integration (methodologies, prototype tools, and commercial tools), and the second one, works using FT in CAD phase to reduce the environmental impact of one life cycle stage such as material selection or manufacturing.

Finally, we propose an approach based on FT for ecodesigning products to promote simple new ecodesign tools which will help the inexperienced designer.
