I was thinking about this for a while. Why are common doors designed as they are today?
I'm particularly interested in the use of the door knob. I was thinking that it would be more useful and practical if it was located at the bottom and used with our feet. Like somewhat of a pedal design.
This way, our hands are free to carry more stuff when passing through. And you just close it with your heel on your way out. In addition, door knobs are used with all sorts of hands, making them dirtier than all sorts of things. No one ever cleans the door knobs. Ever.
And the lock, if needed, can remain to be used with your hands, using a standard key.
While the door handle for our hands seems more natural since we mostly rely on our hands when it comes to tools and technology, this seems like a smarter design. Despite that, I haven't came across this kind of doors yet.
Why would we choose the hand-knobs over feet-knobs, other than the tradition (which seems to be the reason behind it)?
This is actually connected to my idea of finding the best door design that relies purely on mechanical technology. No electronics or stuff, just pretty old rusty metals and gears. (Throwing something like the automatic eye-scan-lock, auto-slide doors out of the window.)
Are my pedal-doors superior enough over the classic doors, or perhaps for some reason actually not? Any ideas to enhance them? (Don't want to over-complicate it, simple & optimized for everyday life is good enough.)
