Purpose

The use of shoulder protectors is strongly recommended when carrying objects on the shoulder to ensure the health and safety of workers. Thus, this study aimed to develop and verify an ergonomic shoulder protector that considers human body shape and carrying posture from an ergonomic perspective. Ultimately, this study will present a shoulder protector with enhanced fit and safety for carrying workers at construction sites.

Design/methodology/approach

The shoulder protector was designed and printed using three-dimensional printing technology with variable side neck points and shoulder point heights to reflect the human body's shoulder line shape and to position the carried object stably on the shoulder. The developed shoulder protectors were evaluated in terms of their fit according to the work posture of the carrier, adherence upon motion and durability through structural analysis.

Findings

The design of the shoulder protector for carrying workers followed the shoulder line. It is best placed above the side neck point by 1.0 cm and above the shoulder point by 2.0 cm. Its length is slightly shorter than the human shoulder for superior fit and safety.

Originality/value

The final shoulder protector (FSP) for carrying workers reflects the body curvature while enhancing fit and safety by considering activity and protective factors. As functional studies and evaluations on the need for protectors are scarce, this study provides fundamental data in the evaluation of protective gears.

一种基于人体工学的立体肩部保护器，适用于工人

目的

强烈建议在肩上携带物品时使用护肩，以确保工人的健康和安全。因此，本研究旨在开发和验证一种符合人体工程学的护肩，从人体工程学的角度考虑人体形状和携带姿势。最终，这项研究将展示一种肩部保护器，该护肩器具有更好的合身性和安全性，可用于在建筑工地运送工人。

设计/方法/方法

护肩采用3D打印技术设计印刷，侧颈点和肩点高度可变，反映人体肩线形状，将携带物稳定地定位在肩部。通过结构分析，根据载体的工作姿势、运动时的附着力和耐用性，对开发的肩部保护器的合身性进行了评估。

发现

承运人护肩设计沿袭肩线。最好放在侧颈点上方 1.0 厘米，肩点上方 2.0 厘米。它的长度略短于人的肩膀，以提供出色的合身性和安全性。

原创性/价值

用于搬运工人的最终肩部保护器 (FSP) 反映了身体曲率，同时通过考虑活动和保护因素来增强合身性和安全性。由于对保护装置需求的功能研究和评估很少，因此本研究为保护装置的评估提供了基础数据。
