一种租赁式轮椅的设计实现与工程分析

Designing implementation and engineering analysis of a rental wheelchair

为了解决目前租赁式轮椅存在的诸多问题,如用户需求不明确、人机尺寸不合理、忽略租赁的独特性等,对租赁式轮椅进行设计研究.应用产品设计方法,通过分析用户群体的不同特性,明确了可折叠、通用性、简易性、耐用性四个设计点;通过提取在轮椅设计中人体工程的坐姿尺寸,结合设计点,经筛选得出了一种可折叠型的租赁式轮椅.确定了设计方案的结构尺寸、材质及加工工艺,工程建模输出后的产品模型与最初的设计点吻合.租赁式轮椅作为公共场所特殊人群临时使用的交通工具,具有一定的需求性.

In order to solve several problems, such as customer requirement uncertainty, irrationality of man-machine dimension, ignoring rental characteristics and so on, which cause the mistaken idea of design, this paper will do some research about rental wheelchair design. Through applying methods of product design, different characters of user group were analyzed, then 4 design factors such as folding, general-utility, simplicity and durability were extracted. And based on ergonomic analysis of the sedentary posture size, a new kind of folding rental wheelchair was designed by sifting schemes. Through establishing structure dimension, material, processing technology and using the engineering software, this product model was identical with the design factors. As the temporary public conveyance for the particular people, the rental wheelchair has certain market demand.
