Ankles can benefit from the elastic tube bandage (ETB) by providing the ankle joint with compression, but partial high- or low-pressure leads to body discomfort. The aim of this paper is to propose a method for analyzing the ankle shape with the fabric compression which is basis on the comfortable pressure on human body. First, a standard model of ankle is established from the scanned data of 306 samples, and the mapping of the fabric shape curves on ankle were constructed by the U-direction convex curves of the model. The positions or areas of maximum and minimum pressure are then marked by extracting the curvatures of the fabric shape curves. According to the Laplace’s Law, the sizes of ETBs can be calculated given that the value of comfortable pressure on human body is the maximum one. The data of calculation is approximate to the relevant previous studies which has the same parameters of ETBs. Nine groups of the ankle shapes from the database are discussed, each group has a proportional coefficient to the standard model, and the result shows that six sizes of ETBs with comfort pressure match for the nine groups. These can be applied to the comfort design, and the method proposed can boost size customization of ETBs, as well as will inspire the research on other elastic compression garments.

弹性管状绷带设计的踝关节形状和压力统计分析

踝关节可以从弹性管绷带 (ETB) 中受益,因为它可以为踝关节提供压力,但局部高压或低压会导致身体不适。本文的目的是提出一种基于人体舒适压力的织物压缩分析脚踝形状的方法。首先,从306个样本的扫描数据中建立了踝关节标准模型,利用模型的U向凸曲线构建了踝关节织物形状曲线的映射。然后通过提取织物形状曲线的曲率来标记最大和最小压力的位置或区域。根据拉普拉斯定律,当人体舒适压力值最大时,可以计算ETB的大小。计算数据与之前的相关研究具有相同的ETB参数。讨论了数据库中的九组脚踝形状,每组都有一个与标准模型的比例系数,结果表明九组具有舒适压力的六种尺寸的 ETB 匹配。这些都可以应用于舒适性设计,所提出的方法可以促进ETB的尺寸定制,也将启发其他弹性压缩服装的研究。
