What it does
The self-cleaning door handle is combining with advanced photocatalytic(光催化) and blacklight technology. A light source activates the door’s handle coating, telling it to start cleaning. It can reduce the risk of infection by contact and improve the cleanliness of a space.
How it works
The working principle of the product is that a thin advanced photocatalytic coating can effectively remove bacteria(细菌) on the surface of a substance.A consistent UV light source inside a transparent glass door handle is required to activate the door’s handle coating on the outer surface for disinfection, so a generator is used to provide electricity to light up a UV LED lamp by the motion of an opening and closing door. Then, the door handle can clean by itself.
Design process
We made the first version by using stainless steel(不锈钢).However, it caused the door handle to be heavier. Then, we tried aluminum (铝), which made it light and easy to fix. We also improved the generator output which effectively turned energy from door movement into a light source.
How it is different
Our innovative(革新的) design is simple,effective,and attracive. It has an elegant smooth shape, and its minimalist appearance stands out in today’s world of inventions. Nowadays, people use chemical cleaning materials to clean up public areas but it harms the human body. Our design can be used for a long time and is effective. It can self-clean after each use. In the door lock and door handle market, it is a unique design because there are no similar products.
Future plans
In the future, we will commercialize the product and hope that it can compete on the market with similar products. We are going to connect with public properties, for example, shopping malls, hotels, hospitals and public restrooms, where the risk of spreading infection is higher.
