新冠肺炎大流行创造了全球对个人防护装备的巨大需求。在新冠肺炎大流行的背景下,面罩是一线工作人员个人防护装备的重要组成部分,为面部提供保护,使其免受含病毒液体的飞溅和喷射。现有的面罩设计和制造程序可能无法生产和分配足够数量的面罩,以满足全球需求,特别是在低收入和中等收入国家。本文介绍了一种简单、快速、经济的曲折折纸技术,用于将柔性塑料材料的平板转换为面罩,以控制感染。进一步表明,该设计可以使用从手工技术到大批量模切和压痕的各种制造方法来生产。这表明,根据现有的材料、制造能力和劳动力,该设计有可能应用于各种环境中。提出了一种易于实现和灵活的物理-数字参数设计方法,用于快速探索和改进设计的变化,潜在地允许其他人调整设计,以适应广泛的人体工学和保护要求。
The COVID-19 pandemic has created enormous global demand for personal protective equipment (PPE). Face shields are an important component of PPE for front-line workers in the context of the COVID-19 pandemic, providing protection of the face from splashes and sprays of virus-containing fluids. Existing face shield designs and manufacturing procedures may not allow for production and distribution of face shields in sufficient volume to meet global demand, particularly in Low and Middle-Income countries. This paper presents a simple, fast, and cost-effective curved-crease origami technique for transforming flat sheets of flexible plastic material into face shields for infection control. It is further shown that the design could be produced using a variety of manufacturing methods, ranging from manual techniques to high-volume die-cutting and creasing. This demonstrates the potential for the design to be applied in a variety of contexts depending on available materials, manufacturing capabilities and labour. An easily implemented and flexible physical-digital parametric design methodology for rapidly exploring and refining variations on the design is presented, potentially allowing others to adapt the design to accommodate a wide range of ergonomic and protection requirements.
