Abstract

Abstract:

In order to improve the ease of putting on/taking off of pants for people with lower limb disabilities, we divide them into two groups: people with mild and severe lower limb disabilities, design an orthogonal experiment and probed into the effect of 3 factors, clothing fastener, opening position and opening size on their try-on time of barrier-free pants, use range analysis and variance analysis to get an optimal level combination and make a subjective evaluation on the improvement effect of pants. The results indicate that the opening size is the main factor affecting the ease of putting on/taking off of pants and has a very significant effect on the try-on time. The fastener is an important factor, which has a significant impact on the try-on time. The opening position is a secondary factor, which has an insignificant effect on the try-on time. For people with mild lower limb disabilities, when the opening size is 25 cm, the fastener is hook & loop, and the opening position is in the middle, the pants have the best ease of putting on/taking off, and the total time taken to put on and take off is the shortest. For people with severe lower limb disabilities, the opening size is 95 cm, the fastener is a zipper, and the opening position is in the middle of the leg, the pants have the best ease of putting on/taking off. Moreover, the improved barrier-free pants through the optimal level combination are better than unimproved ones in terms of comfort and ease of putting on/taking off.

Key words: people with lower limb disabilities, barrier-free design, orthogonal experiment, variance analysis, range analysis

摘要：

为提高下肢残障群体裤装的穿脱便利性,分轻度和重度下肢残障群体两个组别,设计正交实验,考察了服装紧固件、开口位置、开口大小3个因素对其无障碍裤装试穿时间的影响,利用极差分析和方差分析得到最优水平组合,对裤装改进效果进行主观评价。结果表明:开口大小是影响裤装穿脱便利性的主要因素,对试穿时间有非常显著影响,紧固件为重要因素,对试穿时间有显著影响,开口位置为次要因素,对试穿时间影响不显著。对于轻度下肢残障群体而言,当开口大小为25cm、紧固件为魔术贴、开口位置设在中间时,裤装的穿脱便利性最好,穿脱所需总时间最短;对于重度下肢残障群体而言,开口大小为95cm、紧固件为拉链、开口位置在腿部中间,裤装的穿脱便利性最好。根据最优水平组合改进后的无障碍裤装在感觉舒适性、穿脱方便性的效果上均优于改进前的裤装。
