针对疫情时期防护用口罩不适问题的结构改良设计

Structural Improvement Design for Uncomfortable Problems of Protective Masks During Epidemic Period

目的针对防护用口罩在长时间穿戴时普遍存在的不适问题进行改良设计,以求提高人体穿戴体验、避免不适感对人体产生负面影响。方法基于U-TRIZ理论的解题方法,探讨了防护用口罩的不适问题,提出疫情突发时期物资紧缺、社会生产压力大、医护人员长时间工作等特殊情况下的口罩改良原则和结构改良设计方案,并通过设计实践和穿戴实验对改良设计方案进行可行性验证。结论经新冠肺炎疫情期间的穿戴实验证明,可调节式口罩带、分散压力式气囊口罩沿和眼镜防滑条的口罩结构改良设计,可有效解决现有口罩大部分不适问题。有效改善因压力不均而脸部疼痛、因口罩带拉力而耳部疼痛和眼镜滑动的问题,有效缓解因密合度不够而眼镜起雾的问题,使口罩的穿戴舒适度提升,同时更加契合面部形态、缩短穿戴时间。

This paper is designed to improve the discomfort problems that is common in protective masks when worn for a long time,in order to improve the wearing experience and avoid the negative impact of discomfort on the human body.Based on the U-TRIZ theory,the discomfort of protective masks is discussed.The principle of mask improvement and structural improvement design schemes for special circumstances such as shortage of materials high social production pressure and long working hours of medical staff during the outbreak of epidemic are proposed.And the feasibility of the improvement design was verified through design practice and wearing experiments.During the COVD-19,the wearing experiments showed that the adjustable respirator belt,pressure-dispersing airbag mask edges and anti-slip bars for glasses can effectively solve the most of uncomfortable problems caused by long-term wearing of existing masks.Moreover,the problem of face pain due to uneven pressure,ear pain due to the tension of the mask and glass slippage can be effectively alleviated,and the problem of glasses fogging due to insufficient fit can be effectively alleviated,and the wearing comfort of the mask can be improved.As a result,the mask can fit the face more closely,and the wearing time can be shortened.
