“…Once the design scheme is fixed, for the next design phase, i.e., detailed design phase, it is extremely difficult, costly, time-consuming, or even impossible to remedy the shortcomings of a poor design scheme [7]. Embodiment design phase starts with the concept variants generated from conceptual design phase and aims to develop the overall layout and preliminary design solutions that meet the requirements [13,14]. When the preliminary design schemes are acquired, the evaluation and optimization will be performed to seek the optimal design scheme [13].…”

“…When the preliminary design schemes are acquired, the evaluation and optimization will be performed to seek the optimal design scheme [13]. However, the decision made in this phase only considered technical and economic indicators [14], where environmental indicators (such as carbon emission) were not taken into account. Therefore, considering environmental impact of the product life cycle at embodiment design phase is critical and needs to be further studied.…”

Greenhouse gas emissions have become one of the most attractive global concerns for sustainable development. To reduce product life cycle carbon footprint, planning should begin at embodiment design phase. Accurate assessment of carbon footprint is the foundation of carbon footprint reduction. However, existing carbon footprint models are not applicable to embodiment design phase due to incomplete and limited design information. With this in mind, this paper proposes a carbon footprint model for embodiment design based on macro-micro design features. First, a Function-Structure-Feature (FSF) model for embodiment design is established to convey the design information. The concept of design features is introduced (as both macro and micro level). The macro design feature denotes the different operational states of the product and the constraint relationships between parts. The micro design feature denotes specific properties of parts. Then, a model of product carbon footprint based on design features is presented through analyzing the relationships between macro-micro design features and product carbon footprint. The feasibility of the proposed method is demonstrated by a gear hobbing machine. The amount of carbon footprint from each type of design feature can be predicted. Through the optimization of design features, product life cycle carbon footprint has decreased significantly.
