基于生命周期理论的可持续儿童推车设计

目的 针对童车市场出现的产品生命周期短、回收再利用难和产品类别过度细分等问题，从可持续设计的设计原则和设计方法出发，结合用户需求分析，进行儿童推车再设计，以解决当前儿童推车造成的家庭开支大，占用空间，实用性不强等可持续设计问题。方法 基于产品全生命周期理论对儿童推车的可持续性进行分析，将儿童推车生命周期各个阶段的可持续利用率最大化，再应用模块化理念进行结构设计，通过分析现有儿童推车的功能与结构，提炼其共性特征和可实现多功能变换的功能与结构模块。结论 使该多功能童车通过功能结构模块的变换，实现在儿童推车、购物拖车与助行拐杖之间的功能转化，以及拆卸后座椅的再利用。应用可持续儿童推车设计流程，有效地延长儿童推车的生命周期，发挥儿童推车使用后的余热，满足用户多样化、个性化的需求，减少对资源的浪费和经济损失。

Sustainable Design of Stroller Based on Product Life Cycle

The work aims to redesign the stroller combined with the analysis of user needs from the principle and method of sustainable design in view of the short life cycle of products, the difficulty of recycling and the excessive subdivision of product categories in the stroller market, so as to solve the sustainable design problems caused by the current strollers, such as large household expenses, space occupation, low practicability, etc. The sustainability of strollers was analyzed based on the product life cycle, the sustainable use of strollers at each stage of the life cycle was maximized, and then the modular concept was applied for structural design. By analyzing the function and structure of existing strollers, the common features and the functional and structural modules that enabled multi-functional transformation were refined. Through the transformation of the functional structure module, the multifunctional stroller realizes the function conversion from the stroller, the shopping trailer and the walking crutches as well as the reuse of the seat after disassembly. The application of sustainable stroller design process can effectively extend the life cycle of stroller and give full play to the residual functions except ordinary use, to meet the diversified individual needs of users and reduce resource waste and economic loss.
