A design draft with technical proof of function and feasibility is expected.

The adjusting element to be developed should, in contrast to existing door stops/door catch hinges with pre-defined detents or holding stops, realize an infinitely variable positioning and holding function of a vehicle door. This will provide the operator with greater comfort, e.g. in tight parking situations.

The installation position of the adjustment element and the mounting points are to be adopted from existing door stops, i.e. centrally between the door hinges (see Technical Framework)

Technical Framework 1 Technical Framework 1

The opening range of the door and thus the infinitely variable functional range of the adjustment element is between 0° and 90°. The adjustment force during door movement should be <20N and the holding force of the positioned door between 30-50N, both measured at the center of the outer door handle.

For the competition, we expect a target price calculation with regard to cost for planned quantities of more than 50,000 units per year.
