HYDE door handle by alexandru coman from romania

my concept started with a simple form, which through a rotation of 90 degrees can turn into a more dynamic form. to do this rotation of 90 degrees and keep the continuity of edges, the section must be square. also the thickness of the door handle will determine the angle of rotation. i chose a thickness of 30 by 20 millimeters, so the angle will be about 40 degrees. the change in shape is allowed with the key that works on the principle of the screwdriver and triggers the mechanism to lock or unlock the two forms of the door handle. therefore the key has a double function, adding the opening - closing the door.
the material suggested for this design is stainless steel. i chose this material because of its durability over time.
