Designing mobile electronic products for easy disassembly is crucial for promoting resource recycling. However, many current approaches overlook the need to consider the disassembly of parts from the perspective of the overall product structure and practical recycling requirements, leading to potentially suboptimal or unnecessary optimization strategies. This study introduces a novel visual disassembly information model called the "Peony Diagram." This model uses a multi-layer ring diagram to depict part hierarchies and constraint relationships and employs specific symbols to convey part disassembly information and highlight key components. The difficulty of disassembling individual parts is assessed by calculating difficulty coefficients based on quantified disassembly information in the model. To validate the model's effectiveness, a smartphone was used as a case study to determine the shortest disassembly sequence and evaluate disassembly difficulty for both single and multiple parts. The findings demonstrate that the proposed method can accurately assess the ease of disassembly of key components during product repair and recycling. Consequently, it can suggest strategies to enhance recycling and disassembly efficiency and reduce the difficulty of disassembling critical parts.
设计便于拆解的移动电子产品对于促进资源回收利用至关重要。然而，当前许多方法忽视了从产品整体结构和实际回收需求的角度考虑零件拆解的必要性，导致可能出现次优或不必要的优化策略。本研究引入了一种名为“牡丹图”的新型可视化拆解信息模型。该模型使用多层环形图来描绘零件层次结构和约束关系，并采用特定符号来传达零件拆解信息并突出关键组件。通过基于模型中的量化拆解信息计算难度系数来评估单个零件的拆解难度。为了验证该模型的有效性，以智能手机为例进行研究，确定最短拆解序列，并评估单个零件和多个零件的拆解难度。研究结果表明，所提出的方法能够准确评估产品维修和回收过程中关键组件的拆解难易程度。因此，它可以提出提高回收和拆解效率的策略，并降低拆解关键零件的难度。
