摘要
随着时代的发展,物质生活的丰富,广大女性对足部保健日趋重视,不再仅仅满足于鞋的装饰性,同时也注重鞋的功能性、舒适性、健康性,对高跟鞋舒适性的研究是现代社会消费和发展现状的需求。
     高跟鞋让许多女性为之着迷,但是由于它的足底压力分布不合理,局部压力过大,也给女性带来了一些困扰与痛苦。一些女性,由于惧怕高跟鞋造成的过大的局部压力带来难忍的疼痛,而想穿却不敢穿高跟鞋;也有一些女性由于经常穿着高跟鞋,而引发了一些如鸡眼、胼胝、大小拇趾增大、脚趾外翻鼓槌状等足部疾病。而且足是人体神经末梢聚集的部位,足底反射区连接着人体的五脏六腑,如果压力过大,会使血液流通不畅,从而影响了人体器官的健康。因此,无论是从感觉舒适性,还是从足部和人体器官的健康角度来讲,都有必要对女性朋友所钟爱的高跟鞋的压力舒适性进行研究。对于高跟鞋来说,造成不舒适的压力主要是足底压力,因此本课题就从鞋的结构方面来研究高跟鞋的足底压力舒适性。
     鞋底结构是影响高跟鞋足底压力舒适性的主要部位,经过分析在众多鞋底结构组成中,跟高、跟粗细、鞋底弧线造型、防水台、鞋內底凹凸是影响高跟鞋足底压力的主要结构因素。本课题的主要研究任务,就是探讨这些结构因素对高跟鞋足底压力分布的影响机制,并提出合理的结构设计原则和方案,以改善高跟鞋的足底压力舒适性,克服高跟鞋的“前足压力过大”影响舒适性的主要难题,为企业的高跟鞋设计与制作提供理论参考。
     足与鞋是相互联系的一个整体,深刻了解人体足部结构和运动生物力学是设计制作舒适的高跟鞋的前提,鞋的设计必须“以足为本”,满足人体足部的结构与运动力学,符合了足部结构和运动规律的鞋才是舒适的鞋。本课题从人体足部生理结构和运动力学两方面,对人体足部进行了分析,为高跟鞋的设计提供理论基础。
     在压力研究中,压力测试是不可缺少的环节,国内外可用于足-鞋之间压力测试的系统主要是鞋垫式足底压力测试系统。本课题依据测力鞋垫系统的思想,以Labview程序开发软件和一些电路、Flexiforce薄膜柔性传感器等硬件设备为条件,开发了一套可以进行足-鞋之间动、静态压力测试的“Labview压力测试系统”。改系统的成功开发,为课题的顺利开展提供了条件基础。
     本课题在充分的理论基础和条件基础上,通过一系列实验探讨了一些鞋底结构因素对高跟鞋足底压力的影响机制,并得到了一些关于改善高跟鞋足底压力舒适性的设计要点,从而为达到舒适性与美观性的相对统一贡献力量。
With the development of society and the rich material life, women is paying more and more attention on foot-care. They are not only content with the appearance, but also put forward higher requirements for the comfort and functionality of shoes. The research on high-heeled shoes comfort is because of the consumption demand.
     High heels are appealing to many women, but aslo bring on much discomfort and pain because of the overlarge partial pressure. Some women have to give up high-heeled shoes for the fear for pain; and aslo some suffer from foot disease, such as corns, callus, pollex valgus, et al. Nerve endings assemble together on the foot to form reflection area which connects to body organs. If the plantar pressure is overlarge, the blocked blood circulation will affect human health. Therefore, weather from feeling comfort or human health, it’s neacessary to do research on female dearly beloved high-heeled shoes. For high heels, the discomfort is mainly caused by plantar pressure. This subject put emphase on the plantar pressure to find the relationship between the structre and comfort.
     The structre of shoe sole is an important part which imfluence the comfort of high-heeled shoes. In all constituents of the shoe sole, heel height, heel thickness, the curve shap of sole, plate form, the unevenness of shoe insole are the key factors which influence the plantar pressure distribution. The main task of this subject is to find the influence over plantar pressure caused by these factors and give out the scientific principle and plan for structre design to improve the high-heeled shoes comfort. This subject helps to overcome the hard problem that the pressure under the forefoot is overlarge and supply reference to the high-heeled shoe design for the corporation.
     Foot and shoe are in an interactive systeam. A deep understading of foot structre and sports biomechanics of foot is the prerequsition of comfortable high-heeled shoes. To design shoes, it’s necessary to be foot-oriented. The high-heeled shoes only can be comfortable in accordance with the foot sports biomechanics. This subject analyses the foot sports biomechanics with high heels in detail to provide the theorotic basis for the structre design and production of high heels.
     In all pressure research, pressure measurement is essential. At home and aborad the systeam that can be used to measure the pressure between the foot and shoe is mainly the insole plantar pressure distribution measurement system. This subject develops a measurement systeam based on the programme development platform“Labview”and flexible sensors“Flexiforce”. This systeam called“Labview pressure measurement systeam”can measure the static and dynamic pressure. The development of the systeam provides good working conditions for this subject.
     With the sufficient theoretical basis and conditions , this subject explores the influence on the plantar pressure by some key structre factors, and get some useful principles and tips for shoe structre design to contribute to the relative unity of comfort and beatuy
