The Problem Addressed
Pretty often, of two (or more) people sharing bed or room, one has to get up earlier. Standard sound-based alarm clocks wake up everybody. A silent alarm clock would wake up the early riser only.
Two Key Features of the Silent Alarm Clock
1.Bluetooth Vibrating Wrist Band: the alarm clock would have a bluetooth vibrating wrist band (see an example)
2.Focused Light Beam: the alarm clock would to turn a focused light beam on.
A focused timer-operated water sprayer would be a great silent alarm clock. The alarm clock would push the button of an electronically operated water sprayer.
The main advantage of this solution is that it's more effective than a sound- or light-based alarm clock that you can switch of and keep sleeping. The water sprayer make the pillow wet and thus unpleasant to sleep on.
