My submission isn’t necessarily a re-invention, but an implementation. Right now, most of the prevalent doorknobs/door levers, have flushed surfaces for the key hole. This can create quite a problem for the elderly, visually impared, or people with diseases that inhibits their dexterities.  This is why my submission is a doorknob with an indentation that would guide the keys to the key hole, much like car ignitions. This is why I said that it wasn’t necessarily a re-invention, this thinking already exists, it’s just that I am suggesting to implement it to something that may help many people, and better their life even just a little. Another possible edition would be to implement levers either on top or on the side. I found that levers that are sometimes too short when protruding out on the side tends to slip once my hand has pushed through to the bottom. If it is in on the top, the lateral motion can still guide the lever but it will catch the hand once it has reached it’s limit to the side. Also, if the lever were to be placed on the side, I would make it so that it would have a catch at a certain angle before it reaches 90 degrees. In that way, a persons hand will not simply slip off. I am suggesting to place levers on doorknobs since the curvature of the doorknob is a lot more gentle on the hands than a regular lever. In conclusion, the most important aspect of this submission is to add a guide to the keyhole as to simplify the process of unlocking a door.
