可拆卸设计 (DfD) 是一种设计策略,旨在使产品在其生命周期结束时能够轻松、经济高效地分离其组件和材料。通过优先考虑非破坏性分离,DfD 有助于维修、再利用、再制造和高纯度回收。关键技术包括使用机械紧固件而非粘合剂、模块化结构以及清晰的材料标签,以最大限度地提高价值回收率。

Design for Disassembly is a practical application of circular economy principles. Its technical execution involves a deliberate choice of product architecture and joining methods. Designers employing DfD minimize the variety and quantity of fasteners, opting for common types like screws instead of permanent bonds like glue or ultrasonic welds. Products are often designed with a clear hierarchy, allowing major modules to be removed without disturbing the entire assembly. Materials are selected not only for performance but also for their compatibility in recycling streams, and are clearly marked with international recycling codes to aid in sorting. This approach stands in contrast to conventional Design for Assembly (DfA), which often prioritizes initial production speed and can lead to integrated, inseparable designs that are destined for landfill. The novelty of DfD was its explicit consideration of the end-of-life phase as a critical design constraint, shifting the perspective from a linear ‘take-make-dispose’ model to a circular one where components and materials retain their value through multiple life cycles.
