Scientific Design of Workplace for Engineering in Sewing Process

Abstract

The research of the sewing process regarding strain and stress is presented. The seamstress usually performs her work in sitting position. The human body is constructed for moving and any position over a longer period of time, regardless of how comfortable it might be, is a forced position and one can say that during the process of sewing the worker sits in a forced position. Such a forced position is even more stressed when the workplace is not ergonomically constructed and the seamstress at the sewing machine sits in a forced position. An experimental design of an ergonomically designed workplace for the seamstress is presented, in which all methods for a detailed state analysis of a workplace have been implemented (MTO, OADM, MADM, OWAS) Based on the acquired data, a suggestion for an ergonomically designed workplace has been proposed and realised in the real surrounding. A comparison between the positions of the workers in ergonomically undesigned and ergonomically designed workplaces was conducted. It was found that the position of the seamstress in an egonomically designed workplace was more suitable. Following, the worker‘s stress and strain because of the position during the sewing are lower and within reference values.
