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 minimize 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 decompose 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. However, it caused the door handle to be heavier. Then, we tried aluminum, 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 design is simple, effective, and attractive. 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.
Awards
In addition to winning the James Dyson Award, it has also received the Gold Award, and in 2016, it was featured in the 44th International Geneva Inventions Exhibition.

It was late, about 10:15 p.m., when Janice Esposito arrived at the Bellport train station; she jumped into her Honda Odyssey and began the 20-minute drive home to her husband and seven-year-old son. She’d just returned from visiting her mother and had traveled the route many times before. She practically _______ on autopilot: a left onto Station Road, then a left on Montauk Highway, and then—wham! Out of nowhere a car T-boned Esposito’s minivan, _______ her to move backward some 100 feet onto the railroad tracks. She _______ in the minivan, bruised (撞伤) but mostly just knocked out by the _________ and the airbags.
As it happened, Pete DiPinto was getting ready for _______. He’d just closed his book and was getting under the covers when he heard the sound of metal on metal and breaking glass coming from not far outside his bedroom window. A volunteer_______and retired teacher, DiPinto, 64, never _______to think. He grabbed a flashlight and, still dressed in his pajamas (睡衣), ran out the door. “Any firefighter would have done what I did,” he told Newsday. “We’re always on_______.”
The first car he came upon, 2,000 feet from his front yard, was the one that had _______Esposito. Once DiPinto concluded the driver was OK, he looked around and __________Esposito’s minivan positioned on the railroad tracks. And then he heard a terrible sound: the bells signaling an oncoming __________.
“The gates were starting to come down,” he told Newsday. “I see the headlight of the train.” DiPinto ran quickly to Esposito’s minivan and knocked on the driver’s side window. She __________ looked at him, her eyes unfocused. “I don’t know where I am,” she said. She seemed unhurt. “Honey, you’re on the railroad __________,” DiPinto shouted. “We have to get you off right now!” He pulled hard on the __________, but the door was crashed in and __________. The heavy diesel train, traveling at 65 miles per hour, was moving fast toward them. DiPinto ran to the passenger side and threw open the __________. “Please, don’t let her be __________,” he thought. He pushed aside the deflating (瘪了的) airbags, grabbed Esposito’s arms, and__________her toward him across the passenger seat until he could help her out and quickly get her to ____________ behind a signal box a few feet away. Within six seconds, he estimated, the train crashed into the minivan. “It was like a Hollywood movie,” DiPinto told reporters the next day.
But this one had a twist. “Last night,” South Country Ambulance chief Greg Miglino told CBS New York, “the__________ arrived in pajamas, not in a fire truck.”
