Safety Knob / Door handle

Safety Knob

Many Asian countries have undeveloped Social welfare systems despite of its increasing of population aging. It is often seen some of elderly people have suffered and died due to negligence from lack of communication.

The design of this “door handle” is for those senior citizens who need attention from their solitary lives in emergency.

The door handle has a fingerprint recognizer which alerts danger when not activated for a certain period of time. As the door handle can alert its danger to neighbors for their prompt action by displaying signs and words of “help”.

It could save their lives.
