Jinan: A high school girl invents an anti-fall safety window

On the 1st, “After half a month, see the child accidentally falls downstairs” reported that a girl from Zhangqiu fell from the 3rd floor and was not out of danger as of the time of the press release. In response to the phenomenon of children falling from the building, a high school student in Licheng County invented a fall protection window and is applying for a patent. He hopes to apply it in the future to reduce the occurrence of a tragedy.

“This invention is designed for accidental fall of children.” On the afternoon of the 1st, Yuan Mei, a student from Grade 2 of Licheng Second Middle School, introduced design drawings. The reporter saw that the sketch on the drawing was divided into two parts. Part of it was a normal window. It was no different from an ordinary window. The lifesaving bearing device was closed. The other part was a window in the rescue state. The life-saving bearing device was deployed and stretched outside the original window. Cuboid space for carrying falling children.

Yuan Mei introduced that the fall protection window is to install a microwave wall detector above an ordinary window to detect whether there is an object protruding from the window. When an object is detected, the switch device is triggered. The switch controls the load-bearing rods installed on the walls of the lower floor outside the windows and the protective net installed on the load-bearing rods.

"When the human body blocks the path that the radar transmits, the load-bearing rod and the protective net will pop up at the same time and spread out, carrying objects falling out of the window, including children, to prevent accidents." Yuan Mei said that once the window The security space is turned on and the alarm will sound to remind people to rescue.

"This is actually my winter holiday assignment." Yuan Mei said that on numerous occasions she saw children's accidental fall from the building, she thought about how to invent a safety window that could prevent children from falling.

Mounting a microwave wall-type detector above the window, Yuan Mei said that it is based on the principle of the induction door. With the help of Gao Yuefeng, a teacher who is engaged in scientific and technological innovation education, she designed drawings and tried to make physical models. "Currently applying for a patent."

Gao Yuefeng said that in addition to preventing fall, the invention can also provide a temporary shelter for indoor personnel when other accidents such as fires occur. It is reported that Yuan Mei won the first prize of the Jinan Youth Technology Innovation Contest by carrying the anti-fall safety window, and will soon participate in the provincial competition in April.
