The growth in automotive production has increased the number of end-of-life vehicles (ELVs) annually. The traditional approach ELV processing involves dismantling, shredding, and landfill disposal. The "3R" (i.e., reduce, reuse, and recycle) principle has been increasingly employed in processing ELVs, particularly ELV parts, to promote sustainable development. The first step in processing ELVs is dismantling. However, certain parts of the vehicle are difficult to disassemble and use in practice. The extended producer responsibility policy requires carmakers to contribute in the processing of scrap cars either for their own developmental needs or for social responsibility. The design for dismantling approach can be an effective solution to the existing difficulties in dismantling ELVs. This approach can also provide guidelines in the design of automotive products. This paper illustrates the difficulty of handling polymers in dashboards. The physical properties of polymers prevent easy separation and recycling by using mechanical methods. Thus, dealers have to rely on chemical methods such as pyrolysis. Therefore, car designers should use a single material to benefit dealers. The use of materials for effective end-of-life processing without sacrificing the original performance requirements of the vehicle should be explored.
汽车产量的增长使得每年报废车辆（ELV）的数量不断增加。传统的ELV处理方法包括拆解、粉碎和填埋处理。“3R”（即减少、再利用和回收）原则在ELV处理中，特别是在ELV零部件处理中得到了越来越广泛的应用，以促进可持续发展。处理ELV的第一步是拆解。然而，车辆的某些部件在实际中难以拆卸和使用。生产者延伸责任政策要求汽车制造商出于自身发展需求或社会责任，为报废汽车的处理做出贡献。拆解设计方法可以有效解决当前ELV拆解中存在的困难。这种方法还可以为汽车产品设计提供指导。本文阐述了处理仪表板中聚合物的困难。聚合物的物理特性使得通过机械方法难以进行分离和回收。因此，经销商不得不依赖热解等化学方法。所以，汽车设计师应使用单一材料以使经销商受益。应探索在不牺牲车辆原始性能要求的前提下，使用便于进行报废处理的材料。
