| 目的 旨在探索工人在手工搬运工作中最佳的快递箱辅助把手结构，并以该研究为基础提出在快递箱设计时更具舒适性的建议。方法 募集35名被试者使用4种不同辅助把手的快递箱执行2项手工任务（提举任务、携带任务），测试了被试者的最大可接受重量，并记录了其身体部位的不适感、心率和总体喜好度。通过调研法和生理测量仪器测量法得到消费者对4种不同辅助把手的快递箱样本的主观评价和测量数据来分析生理负荷。结果 结果表明，在2项手工任务中，使用4种快递箱时心率的变化均无显著差异，手腕部的不适感也是如此。快递箱C的手掌部位不适感明显高于其他样本。在提举任务中，快递箱C的最大可接受重量和总体偏好等级最高。在携带任务中，快递箱B的最大可接受重量和总体优先等级最高。结论 证明了对于负载提举作业，位置偏上的把手位置是首选。在携带作业中，较低位置的把手对手工作业更友好。此外，提供更多容放手的空间以便轻松握住把手对于提高舒适度非常重要，并且更平滑和更大的接触面积可以减轻手掌的不适感。 |

| Abstract: |
| The work aims to explore a more comfortable auxiliary handling structure of express box for workers' manual operation, and on this basis propose some design recommendations that make the handles more comfortable. A total of 35 subjects were recruited to use four different delivery boxes to perform two manual tasks (lifting, carrying). The maximum acceptable weight of the subjects was tested. And the discomfort of body parts, heart rate and overall preference were recorded. Through the survey method and the physiological measurement instrument measurement method, consumers' subjective evaluation and measurement data of the express box samples with four different types of auxiliary handles were obtained to analyze the physiological load. The results showed that there were no significant differences in heart rate when using the four express boxes in both manual tasks, so did the discomfort in the wrist. The palm discomfort of express box C was significantly higher than that of other samples. In the lifting task, the maximum acceptable weight and overall preference of express box C were the highest. In the carrying task, the maximum acceptable weight and the overall preference of express box B were the highest. Therefore, we have proved that for the load lifting operation, the upper handle is preferred. In carrying work, the lower handle was more friendly to manual work. In addition, providing more room for your hand to easily hold the handle was important for comfort. And smoother and larger contact area can reduce the discomfort of the palm. |
