Meaningful Prediction Parameters for Evaluating the Suitability of Power Tools for Usage

During the usage of power tools, user and power tool are interacting strongly with each other, which is why the working result depends heavily on the usability of a power tool depending on the application (Suitability of Usage (SoU)). The optimization of power tools, in terms of the usercentered design, therefore aims at an increase of the SoU. So far, the acquisition of the SoU is done within broad application tests, with several users and different application situations. Hereby, problems occur because it is often difficult to find an adequate mix of professional trained participants, which are able to evaluate the SoU objectively. To investigate the differences between professional power tool users and trained non-professional users, a study has been performed. In this study, 20 professional and 19 non-professional users tested power tools (cordless screwdrivers and impact wrenches, three different manufacturer each) and evaluated the handles of these systems according to fourteen test items, divided into an observation and a usage phase. By the use of statistical variance analysis, the captured data has been analyzed to investigate the influence on the evaluation through the usage experience of the users. ... mehr
