摘要： 浴缸逐步成为家居中使用广泛的卫浴产品。由于用户身高和体重的差异化，缸体内
曲面形状设计不合理会导致用户使用该产品的舒适度不高。以设计适合我国成年人使用的浴缸为
目标，将压强和接触面积作为舒适度评价指标，根据我国成年男性和女性的P5、P50、P95 百分位
人体尺寸优化缸体曲面。采用Tekscan 仪器测量用户施加在缸体曲面上的压强和接触面积，通过
对10 名测试者使用原曲面和优化后曲面的测量数据分析，表明优化后曲面的峰值压强降低到
58.4%~87.3%，平均压强降低到83.6%~99.4%，接触面积提高到1.50~2.78 倍，有效提高了用户的
舒适度。

Abstract: The bathtub has been widely used as household products. Due to the difference of height
and weight of customers, the unreasonable surface shape will lead to low comfortability as using the
product. In this paper, the pressure and the contact area are made as the evaluating parameters in
order to design a suitable bathtub for adults. The surface of bathtub was redesigned according to
percentile P5, P50, P95 of Chinese adult. The pressure and the contact area were measured by Tekscan
instrument. The data which were captured from the ten testers lying in different bathtub with the
original surface and the optimized surface was analyzed. Results shows that the peak pressure reduces
to 58.4%–87.3%, the average pressure reduces to 83.6%–99.4%, and the contact area of the optimized
surface increases to 1.50–2.78 times. The optimized surface effectively improves the comfortability
of users.
