Abstract

Musculoskeletal disorders are a major occupational health concern among coffee harvesters due to the ergonomic risks associated with improper postures and the traditional basket's attachment. Prolonged exposure to these risk factors can lead to chronic injuries, reduced productivity, and long-term health complications. This study focuses on the design and preliminary analysis of an ergonomic prototype aimed at mitigating these risks and improving working conditions. An ergonomic assessment was conducted using RULA and OWAS methods, identifying high-risk postures that primarily affect the thoracolumbar spine. Additionally, biomechanical evaluations were performed with Kinovea software to analyze movement patterns, joint angles, and force distribution during harvesting tasks. Based on these findings, a prototype was developed to promote healthier postures, improve weight distribution, and reduce physical strain. The proposed design seeks to enhance both workers’ well-being and harvesting efficiency by providing a practical and adaptable alternative to traditional collection methods. Preliminary results indicate its potential effectiveness; however, further testing under real working conditions is recommended to validate its long-term benefits and usability.
