Have you ever almost bumped into（撞上）someone when you open the car door to get out? Ju Wenxuan, an eighth-grade student invented a device（设备）that could make such accidents less.
“I noticed that during rush hours when I was rushing to school and being seated in the back of a car, it was challenging to see if it was safe to open the car door,” Ju said.
Ju found that there are devices that try to solve this problem. But they usually come with the newest smart cars and can’t be added to older cars.
Hoping to make a difference, Ju worked on a new device that can be put on the car’s rearview mirror（后视镜）. With a new and creative technology, the device can find people or cars in the mirror as they get closer. It will sound an alarm when the car’s handle（把手）is pulled if any people or cars are close.
To make sure her invention would be affordable for most people, Ju did some research and discovered that most people wanted a device priced between 100 and 300 yuan. So she worked hard to bring down the cost of her device, such as using as few parts as possible without making the quality low.
“If my invention can become a thing used by more people, then it could reduce accidents. It could also be developed for other uses, such as keeping children safe by sending an alarm when a stranger goes toward them,” Ju added.
