基于低碳约束的产品概念设计方法研究

The Method of Product Conceptual Design Based on Low-carbon Constraint

概念设计对产品的生命周期综合成本具有决定性影响,当低碳成为衡量产品性能的重要指标时,为了在产品概念设计阶段就能提供其全生命周期碳足迹可参考的依据,提出基于低碳约束的产品概念设计思路,确定低碳产品概念设计的目标和边界,讨论低碳概念设计考虑的诸多因素,给出概念设计阶段引入的碳足迹计算模型和以功能结构展开为原理的基于低碳约束的产品概念设计方法。以高耗能产品变压器为例,详解变压器的重要部件之一——铁心的低碳设计方法和模式,对变压器的整体低碳设计具有指导意义。

Conceptual design has a decisive impact on the overall costs of the product life cycle and low-carbon has become an important indicator to measure the product performance. In order to provide a basis reference for carbon footprint of product life cycle in its concept design stage, product concept design ideas based on low-carbon constraint are proposed, the goals and boundaries of conceptual design of a low-carbon products are determined, many factors about conceptual design based on low-carbon constraint are discussed, carbon footprint calculation model in the concept design stage and product concept design method based low-carbon constraint using function structure deployment （FSD） are provided. Iron core which is the important part of high energy-consuming transformer is discussed as example; its low-carbon design methods and mode are illuminated and this way will be instructive for overall design of transformer.
