Self Jamming Door Stopper / Door Stopper

Existing door stoppers available in the market prevent either clockwise or anticlockwise movement of doors and are mostly found ineffective. So the idea was to develop an efficient, easy to use door stopper which will prevent radial movement in both positive and negative directions at any desired opened position of the door. This can be achieved by improving on few fundamental working principles of existing door stoppers. More the door tries to move, more it tries to hold on!
