面向多级循环再利用需求的产品易拆解交互式设计与知识推送研究

Interactive Design and Knowledge Transfer Research of Product Easy Disassembly for Multi-stage Recycling Needs

设计具有更好的循环再利用性、低碳排放及经济性的产品,有效应对绿色贸易壁垒,是未来产品实现生命周期碳中和、资源节约与循环的关键因素之一。传统易拆解设计研究着重强调易拆解设计准则的导入,忽略了多级循环再利用需求对设计目标的影响,存在概念与详细设计过程与多级循环再利用需求及其场景协同交互程度差、知识使用粗略、设计效率低等问题。论文基于产品设计需求和多级循环再利用需求,构建了面向概念设计与详细设计阶段的产品易拆解设计过程框架,面向零部件多级循环再利用策略开展易拆解结构的关联度分析,通过结构聚类形成易拆解模块化结构,构建面向不同设计阶段的设计-评价交互式模型及易拆解性评价体系,探讨了面向多级循环再利用需求的易拆解设计知识推送策略、关键技术与系统开发,并以洗碗机产品的设计案例验证了方法的可行性。

Designing products with better recyclability,low carbon emissions and economy,and effectively responding to green trade barriers is one of the key factors for future products to achieve carbon neutrality,resource conservation and recycling in the life cycle.The traditional easy-to-disassemble design research emphasizes the introduction of easy-to-disassemble design criteria,ignores the influence of multi-level recycling requirements on design goals,and has problems such as poor synergy and interaction between conceptual and detailed design process and multi-level recycling requirements and their scenarios,rough knowledge use,and low design efficiency.Based on the product design requirements and multi-level recycling requirements,this paper constructs the product easy-to-disassemble design process framework for the conceptual design and detailed design stages,carries out the correlation analysis of easy-to-disassemble structures for the multi-level recycling strategy of parts,forms an easy-to-disassemble modular structure through structural clustering,constructs an interactive design-evaluation model and easy-to-disassemble evaluation system for different design stages,and discusses the easy-to-disassemble design knowledge push strategy,key technologies and system development for multi-level recycling needs.The design case of dishwasher products verifies the feasibility of the method.
