Track: Human Factors and Ergonomics Competition

Abstract

The quality of an assembled product and cycle time are significantly influenced by a workstation's ergonomics. A study was carried out to investigate how the cycle time and assembly quality were affected by minor workstation modifications that could potentially reduce the ergonomic strain. For the investigation, a single workstation from the main assembly line—which assembled eight components and was the cause of 43% of quality defects—was chosen.

In an experimental design, the standing surface surrounding the workstation, the assembly height, and the reachability of components were all changed. Many times, complaints or injuries serve as the impetus for ergonomic solutions. This study measured the effects of implementing suggested ergonomic conditions using profit-focused measures to promote proactive action. The findings show that workstation setups varied significantly in terms of cycle time and product quality. The components' reachability showed a notable reduction in cycle time. The standing surface of the workstation and the reachability of the components led to a markedly reduced assembly quality. There was no difference between the current conditions and assembly taking place at the recommended height.
