The demographic change and the high number of work-related musculoskeletal conditions make an analysis of workplaces in production systems regarding the physical and psychological strain on employees more and more important.
Our research group works on numerous industrial projects for the evaluation and planning of workplaces. In the process, work systems in production, logistics and services are systematically analysed and ergonomically designed. Screening methods, measuring methods such as motion capture or electromyography as well as force measurements are used for this purpose. Additionally, the simulation and computer-aided planning of manual or semi-automated workstations is playing an increasingly important role.
Reference Projects
Despite increasing automation, work processes in warehouses are still characterized by manual material handling, such as lifting and carrying heavy loads or repetitive movements of the upper extremities. This can lead to high physical work load on the corresponding employees and ultimately to the development of musculoskeletal diseases.
U-line assembly systems are workstations which are arranged in the form of a U according to the one-piece flow concept. These are hybrid systems in which automated processes are supplemented by manual activities. Depending on the job situation, one or more employees are flexibly deployed in U-lines. Intensive manual work in U-lines can lead to musculoskeletal disorders of the upper extremities and shoulder belt. This depends essentially on the work design. In U-lines, these include short movement cycles with highly dynamic and fine-motor finger-hand and arm movements, for example. U-lines can also cause increased strain on the lower extremities. Due to the circularity of the working persons in U-line assembly systems, lateral steps and rotational movements in the lower back area can occur, representing a significantly different stress pattern compared to “conventional" walking.
As a result of demographic change trade labor is facing some difficult challenges, however there is possibility in this area for creative solutions for the promotion of healthy working conditions. This may assist the employee retention and recruitment, which are seen as essential factors in the demographic orientation of small businesses.
The Institute of Ergonomics of the Technische Universität Darmstadt would like to, in cooperation with the Association of Hessian Chambers of Crafts (JV), the Federal Training Centre of the carpentry and finishing trades (BuBiZA), the Landesinnungsverband the roofing trade Hesse and the Association of color design and building protection Hesse, make a contribution to assist in the demographics-oriented design of these establishments.
