The topic of this bachelor thesis is the development of a golf ball washer. The device uses electrical energy as a source of power. Primary users are big golf courses. A short history of the development of the golf ball is given in the introduction. Existing devices are described in the next step. Functional decomposition, morphological matrix with possible solutions and three concepts are created in the concept generation process. The best evaluated concept is further developed. For the selected concept 3D model is made with required calculations and technical documentation.
