<p>This work is a product development of a product which facilitates enduro drivers swallowing fluid while driving. My own experience of the problem and a custom survey gave me some frames and requirements of how such a product would look. To obtain the different concepts the method of brainstorming was used where I outlined the various proposals. The basic concept was that some kind of pump would build pressure in the liquid and when the user opens the nozzle the liquid will come out without the need to use the mouth to suck. The screening phase consisted of two steps. The first step, a Pugh matrix where I varied reference concepts and four of the six proposals were eliminated. During the second screening phase, two test models were built and I tried out which one I would eliminate. The concept that was left was a simple pump, powered by a battery of9-volt. The pump starts when the user opens the nozzle and stops automatically when the nozzle is closed. This is controlled by a hose which swells when the pump is running and the nozzle is closed. Then the hose begins to swell and affects a small micro switch that breaks the voltage supply to the pump. A check valve makes sure that the liquid remains in the hose and the pump will remain neutral until the re-opening of the nozzle and the hose shrinks. </p>
