What are the advantages of the smart crutches designed by primary school students for the elderly?

Primary school students design smart crutches for the elderly: they can vibrate to remind you when encountering obstacles.

On the 13th, the second Chongqing Youth Science Literacy Competition held a municipal rematch. More than 1,200 primary and secondary school students brought their own scientific and technological innovation works for on-site display and defense. Their wild imagination won the judges' attention. unanimously praised.

This competition is jointly sponsored by the Chongqing Association for Science and Technology, the Propaganda Department of the Municipal Party Committee, the Municipal Education Commission, the Municipal Science and Technology Commission, the Municipal Youth League Committee, the Municipal Federation of Social Science and Technology, and the Municipal Youth Work Committee.

After strict selection, more than 1,200 primary and secondary school students in *** advanced to the municipal semi-finals.

Lazy fish farming system, car wading alarm control function, safe school bus, posture correction desk, smart street light, talking trash can, water temperature speed detector, smart clothes drying rack, mobile phone anti-addiction alarm, etc. The work is not only innovative but also functional.

“My grandma is old and has bad legs, feet and eyesight. She sometimes falls when she goes out, so I designed a smart crutch. It uses photosensitive LED, tracking module, battery box, and DuPont wire and other materials. When the tracking module senses an obstacle in front of the crutch, the crutch will vibrate to remind the user; when it is dark, the photosensitive LED will also light up automatically. " Wang Yuqi, a student at Shahe Primary School in Wanzhou District, said.

Lei Minqian, a student from Liyuchi Primary School in Jiangbei District, showed off the smart and environmentally friendly home system she designed. He said: "The solar panels absorb light energy and convert it into electrical energy and store it to power houses, cars and street lights. Street lights have photosensitive sensors and will automatically turn off after dawn. The LED lights on the roof will light up regularly to remind aircraft of the height of the building. , the thermal sensor in the house will also trigger a buzzer alarm when encountering high temperatures, which can prevent fires.” , photosensitive sensors, buzzer modules, LED lights, etc., to design a smart door system. He said that he often saw children unable to ring the doorbell due to their height, so he thought of turning the door handle into a doorbell sensor. The judging teacher recognized his design very much and suggested that he apply for a patent.

Zhao Kaiyu, deputy director of the Popularization Department of the Chongqing Association for Science and Technology, said that the second Chongqing Youth Science Literacy Competition is open to primary and secondary school students in the city. Through the scientific literacy test in the preliminary round, the production of material packages and practical exercises, the functions of the works in the semi-finals It measures and improves the scientific literacy of young people through display, comprehensive assessment of innovation ability, etc., aiming to promote the integration of science and education, stimulate interest in science, and cultivate innovative talents.

It is reported that the outstanding contestants selected in this semi-final will represent Chongqing and participate in the finals of the Second National Youth Science Literacy Competition held at the University of Science and Technology of China in July this year. Winners of the second prize and above in the high school group of the finals can obtain independent admission recommendation qualifications for colleges and universities across the country.
