If locking the door sends the wrong message and the “Do not disturb” sign doesn't work, now there's a third option: disappear the doorknob. This smartly designed doorknob by Arnaud Lapierre is one of those “why didn't I think of that” moments. You can't make the whole door disappear (or the kids) so why not the knob.

Implications - Products like this take an age-old problem that most people would probably assume has long been addressed and find an altogether new and utterly innovative way to solve it. On top of being functionally ingenious, this kind of invention also has a rewarding novelty aspect that is bound to get people talking long after they see it.
