In my bechelor's thesis I will introduce you to the problem of dirty hands, the use of plastic gloves and many other problems that arise when using a fuel nozzle. The first part of the bechelor's thesis deals with the fuel dispenser, its developement and the types of fuels we use. The handle mechanism and gryp ergonomics are analysed. The analysis identified the key features that define a well designed handle. By researching the users of the gas handle, their needs, wishes and crytics were identified. The second part shows the process of finding a solution with the help of sketches, concepts and the final model. The final solution of the bechelor's solves the problem of dirty hands, consumption of plastic gloves and has simplified control over the amount of leaked fuel.
