In August, 2002, 7-year-old Li Nanjin designed a "mobile phone for the blind" to participate in the "China Children's Haier Science and Technology Award", which is known as the "Nobel Prize for Teenagers" in China. 165438+ 10, the design of "mobile phone for the blind" was selected among the top 30 in the initial evaluation of more than 60,000 entries nationwide, and Li Nanjin was the smallest selected player. 65438+February 17, when Li Nan entered Beijing for defense, she was the "second" among the 30 contestants in junior and senior high schools, and was one of the winners of the first prize of 10, that is, the "Innovation Award". The "mobile phone for the blind" designed by Li Nanjin has five functions: using Braille numeric keys that are convenient to touch, using touch graphic function keys, adding voice prompt system for incoming calls, adding radio function, and choosing efficient and safe batteries to replace power supply. Experts from Haier Group believe that Li Nanjin's design can be completely completed by using the existing technical level. At that time, the Evening News reported Li Nanjin's award-winning situation and her small invention, which attracted readers' attention. She was also rated as one of the top ten news figures in the evening newspaper that year.
Later, Nan Li King invented the telephone for the blind, shoes for the blind and wind-driven mosquito repellent, which won her many awards. Now Li Nanjin is a celebrity in the youth science and technology circle.
The invention comes from life, and her family lives next to a school for the blind.
Many people read Li Nanjin's inventions and will find that many of them are related to the blind. Why? It turns out that Li Nanjin's family lives next to Qingdao Blind School. Li Nanjin often helps students in schools for the blind. On weekdays, she recycles cartons and calendar paper and sends them to schools for the blind to write in Braille. After spending a long time with students in a blind school, she realized many inconveniences in blind people's lives and hoped to help them solve their difficulties.
In a newspaper topic selection of a scientific and technological activity group, Li Nanjin proposed to design a mobile phone for the blind, so that these people who can't see the buttons can use the mobile phone freely. After searching for information and absorbing advanced foreign experience, Li Nanjin's "mobile phone" was successfully manufactured.
In addition to mobile phones for the blind, Li Nanjin's other inventions are also inspired by life. She found it inconvenient for the blind to walk, so she invented shoes for the blind and installed an "antenna" in the front of the shoes, so that the blind can know whether the front end of the antenna meets an obstacle when walking. Seeing the door open and close, there are always flies taking advantage of it. Li Nanjin wrote a paper to explain the theory of wind-driven mosquito repellent.
Invented by interest, my mother almost buried her.
Li Nanjin's mother, Ms. Cao, said that she almost buried her child's creative talent.
Ms. Cao said that at that time, the child said that she wanted to engage in mobile phones for the blind, and she and the teachers in the blind school disagreed. "In fact, most blind people can use ordinary mobile phones normally, so why make them specially? Moreover, this invention has no scientific and technological content, and we don't think it is an invention! " However, Long Fu, a science and technology teacher, is very supportive of Li Nanjin. In the end, Li Nanjin won the Haier Science and Technology Award for his "non-technical" invention. Li Nanjin's good friends in the blind school also praised her invention. At this time, Ms. Cao realized that for children, the real significance of scientific and technological inventions lies in the innovation of thinking. As adults, we should not look at childlike innocence from our own perspective, let alone stifle children's creativity and imagination.
But for the moment, scientific and technological inventions do not involve parents' nerves like artistic expertise and Olympic Games, because making small inventions seems to be of little direct help to the future "development" of primary school students. In this regard, Ms. Cao believes that making small inventions is a child's interest and cannot be viewed from a utilitarian perspective.
Ms. Cao admits that scientific and technological activities do involve some energy of children. But since she became fascinated with gadgets, she found that children love reading, and popular science books at home have become children's good partners; Children are good at observing and care more and more about others. When others encounter difficulties in life, she always hopes to help them solve them. Children love to think, divergent thinking is active, and it is also very helpful for daily study. "It can be said that making small inventions has cultivated children in moral, intellectual and physical aspects."
True love and true love invent infinitely.
