The Need for Ergonomic Studies for the Reduction of Injuries and Redesign of Tools in the Agricultural Sector Through TRIZ

摘要

The importance of the prevention of ergonomic risks in the agricultural sector makes it necessary to carry out studies and have adequate tools to reduce them. Accidents related to inadequate ergonomic conditions at work in the field, whether in agricultural or livestock activities, are considered as factors that affect productivity. The aim of this study is to describe the importance of ergonomic risk prevention in the development of multinutritional blocks for cattle in the Huasteca area in north of Veracruz, Mexico. Using the Rapid Upper Limb Assessment Methods (RULA), Rapid Entire Body Assessment (REBA) and Job Strain Index (JSI) a group of people dedicated to the livestock sector, were evaluated in order to determine ergonomic risk indexes. With the use of the Theory of Inventive Problem Solving (TRIZ), was designed an ergonomic compactor that reduces over stress and possible injuries, allowing the worker to perform his task easily and comfortably.
