Wave / Public coin box


During the popularity of COVID-19, people needed to keep their distance. But because of the need to put coins in the coin box, people will come in contact with others. There will be too much bacteria on the coin box.
Using the inspiration of water ripples and water droplet splashes, we redesigned the coin slot of the coin box. The shape of the water ripple can guide people to place coins. After the coins fall, the coin slot will spray alcohol to achieve the purpose of hand disinfection.
