RingingKnob / alarm clock

RingingKnob

We have been using alarm clock which has button for long time. But there is no obvious connection between “press button” and “daily work at morning” Therefor it’s not effective and irritate users.

Ringingknob uses different method.
First, user set the alarm and hang it on the bedroom-doorknob. When the time is up, just leave the bedroom. And it will stop alarming. Users don’t need to do something irritate at all.

To sensing this action, RingingKnob uses a vibration sensor. So the rotate or touch of the doorknob works as a button in general alarm clock.

Rining-knob is hanging on the doorknob. So, the out side of body is made by rubber.
