Hydraulic Chord / Hydraulic Chord

The water delivered from the waterworks to the public fountain may cause secondary pollution. To solve this problem, we design an osmosis system using the Pascal’s Theory.
A filter is installed at the water outlet and the power of the solar panels allows the switching device to raise and lower the weight ball.
The user presses the button to open the chord device which loosens and lower the weight ball to stabilize the water pressure based on the Pascal’s Theory. The invisible water outlet will eliminate the sanitary concern.
