The locking door handle
Door handles do not get much press that is because they do a job and that is that. However, sometimes somebody comes along with a great idea that completely changes out outlook of such things and thins design could just be one of those things.
It would seem simple enough to have placed a combination lock into the handle, but it is putting it into practice that makes of difference. This is a very useful idea that could have so many different applications.
