In 2007, Corpus Design was commissioned by the company ulrich medical to further develop the design concept of the contrast medium injector of the “CT_Motion”, which had already been created before, in detail until it was ready for series production. The main focus of the design development was on usability as well as on compliance with the usual standards for the usability development process for medical products. The medication and contrast medium bottles in the upper area of the injector, for example, must be easy to see and change by people of different heights. The good visibility and operability naturally also applies to the integrated display with the associated controls. A particularly big challenge was to ensure the tilt stability. On the one hand, the user wants the smallest possible footprint and on the other hand, the unit must not tip over even in critical situations. Last but not least, the appliance must of course also be disinfected quickly and easily by wiping. Of course, the design proposals must be in line with the estimated production costs, as this is the only way to ensure that the product will not only be innovative but also competitive in the market.
