Design and Presentation of a Chairless Exoskeleton Seat

The research in this diploma thesis relates to the design and introduction of an ergonomic chairless seat. This topic greatly helped the author to become better acquainted with CAM-CAD software, ergonomics, human health anatomy, and occupational safety and environmental protection. The obtained research results should increase the productivity and work capacity of the worker. A 20-25 per cent increase in the worker's work capacity and a 50 per cent reduction in the worker's physical and mental fatigue is expected.

Problem

The research in this diploma thesis relates to the design and introduction of an ergonomic chairless seat.

Solution and Method

This topic greatly helped the author to become better acquainted with CAM-CAD software, ergonomics, human health anatomy, and occupational safety and environmental protection. This topic was chosen because the company has an assembly and production department. In both departments, most of the work is performed in a standing position.

According to medical science data, prolonged standing causes inflammation of blood vessels and causes temporary blockage of joints in the spine, hips, knees and feet. This increases muscle pain, lower back pain problems and other discomfort in employees, which affects the productivity and well-being of that person. Potential problems are therefore lower production, more time to achieve goals and more sick leave absences.

Reduced worker productivity thus leads to reduced production and additional costs and threatens the company's reputation. The introduction of this ergonomic seat will help them work more easily, reduce the number of sick leave absences and reduce capacity limitations. The seat is attached to the workers' legs and the person can move freely with it and sit on it and work with ease.

It also helps to increase worker productivity and provides a tireless working atmosphere. With this, they will replace the ordinary chair and thus provide better space management. In addition, it can also be used where ordinary chairs cannot reach.

This is a theoretical diploma thesis with a descriptive working method. A systematic approach to literature search was used. Ergonomics and its branches are explained in detail, and the advantages and future possibilities of exoskeletons are also explained.

A descriptive review was carried out to discover the increase in productivity and the worker's work capacity in relation to ergonomics. This chapter describes the methodology used for the literature search.

Results

The obtained research results should increase the productivity and work capacity of the worker. A 20-25 per cent increase in the worker's work capacity and a 50 per cent reduction in the worker's physical and mental fatigue is expected. This research also provides insight into the future field of application of mechatronic exoskeletons and brain-controlled prosthetics.
