Well, most of us would reason that running into the edge of doors is an
unreasonable thing to do, so maybe you should take your suggestion and
correct the mistake in your reasoning. Maybe you thought it had a
user-servicable part inside? Aside from the catch or lock, doors rarely do,
and the access is not usually obtained at the edge, but from the side :-)
