Case Study
Workplace design for a fitter with a visual impairment and a spinal disability


The company produces lights for work rooms, squares and streets. Considerable restructuring is necessary in the area of ​​accessory assembly. These restructuring measures are associated with downsizing. An employee with a severe disability is also affected by the threat of staff cuts.

Disability and functional restriction of the employee:

The man has a visual impairment and a spinal disease. It should not be used for work in which loads have to be handled frequently, frequent stooping and prolonged standing are required and high demands are placed on the eyesight, since it can only perceive optical information to a limited extent.


The man works as a trained fitter at the company.

Workplace and duties:

The fitter works in the area of ​​accessory assembly. There he screws or assembles the accessories for the lights in a piece. So far, he has done this task in a standing working position at a work table with a corresponding fixed work surface height while covering large gripping areas. The parts to be joined and screwed by him are relatively small and weigh a maximum of 100 grams.Depending on the type of assembly, two to five individual parts are put together and connected with screws. This activity demands, in addition to pronounced fine motor skills of the hands, increased demands on eyesight and upper body mobility. The job causes increasing problems for the fitter due to the disability and can no longer be carried out. An automatic screwdriver with a rotary indexing table is used to keep the fitter's workplace. The system used does not place high demands on fine motor skills and eyesight, as the screws are fed in automatically and the parts are placed in devices on the rotary indexing table. The automatic screwdriver stands on a height-adjustable assembly table with gripping trays and a storage box, which are ergonomically arranged in the employee's gripping area. The employee takes the individual parts from the gripping trays and places the screwed parts in the open-fronted storage box. The height-adjustable assembly table, in conjunction with an ergonomic work chair, allows you to work while sitting or standing. For assembly, the fitter takes the individual parts from the gripping trays and places them on one side of the rotary indexing table in the devices. On the opposite side, he screws the inserted parts with an electric screwdriver, which is attached to a tripod (holding device for the electric screwdriver) via a spring balancer. The tripod was attached to the assembly table in the fitter's grip area. For screwing, the fitter simply pulls the electric screwdriver hanging from the spring balancer in the gripping area down to the rotary indexing table or to the parts to be joined and starts the screwing process - the screws are automatically fed by the automatic screwdriver. After the screwing process, the fitter removes the screwed parts and places them in the open-fronted storage box. The redesign of the assembly workstation is necessary and sensible from a business point of view as well as due to disabilities. Other colleagues (as substitutes) can easily be deployed at this workplace.
