Ergonomics of the Standing Smart: Increasing the Comfort of Standing Workers
Authors: Redha Taïar a
Abstract: The aim of our study is to increase the comfort of users at work by studying the balance and by minimizing the joint stresses. Studying the upright position, the adjusting of his segments to maintain the good balance and decreasing muscular problems are the main elements to highlight in order to improve the everyday (working) life of users. Based on the optimization of new materials, the project consists in validating prototypes destined to improve ergonomics at work and to optimize the comfort of users (new anti-fatigue mats Notrax®). Without mats our results showed a dysfunction balance of the worker which can cause pathologies or repetitiveness and other work constraining factors which can accelerate the process. The distribution of foot pressure obtained (30% and 70%) of the weight of the body is mainly on the right side. This imbalance is very harmful for the human body. With Mats we observed in working situations where people make small movements constantly, the anti-fatigue mats that we tested good properties that give a muscular-skeletal comfort in upright working positions. This can be verified by the constancy of the force evolution curve during the movement.
