The European Union requires businesses to strengthen the interchangeability and detachability of batteries when designing electronic products.
When people read this report, they suddenly felt like a lifetime ago.
Does it mean that the era of "universal charging" is about to return when the battery becomes detachable?
Speaking of "omnipotent", many young people may not have a concept now, but they are unforgettable memories for the post-80 s and post-90 s.
The price of more than ten pieces, two adjustable metal pieces, a fixed transparent clip and a base with a plug are such an "unremarkable" equipment, but it is an epoch-making product.
At that time, "universal charging" helped countless people solve the problem of mobile phone life. Almost everyone had one at that time.
However, few people know that Chen Tianhan, the inventor of this popular "universal charger", was just a high school student who had just turned 18.
From 65438 to 0985, Chen Tianhan was born in an ordinary family in Zhengzhou, Henan.
When he was young, he was full of curiosity about the world and wanted to solve everything.
When he grew up, he began to do it himself. Anything that can be disassembled should be taken apart for study.
At first, Chen Tianhan just took apart his toys. The newly bought toy was opened by him in an instant.
Mom saw parts everywhere and was furious: "Why did you tear them down again? I won't buy it for you in the future. "
Every time he promised not to, but after buying a new toy, he would.
As he grew older, Chen Tianhan began to disassemble toys, and he focused on furniture and electrical appliances.
The newly bought sofa was cut by him with a knife just to find out what was inside and why it was so comfortable.
I don't know how many watches he took from the wall, just because he wanted to try and see if he could put them back.
This kind of sabotage is unbearable for parents, but they beat and scold, and Chen Tianhan still goes his own way.
In desperation, his parents had to make three rules with him: only tear down the old ones, not the new ones; Only dismantle the cheap ones, not the expensive ones; Only simple, not complicated.
Looking at his parents' concessions, Chen Tianhan was ecstatic, and finally he could be "unscrupulous" at home.
Since then, everything from flashlights and hair dryers to electric fans and televisions has been "hurt" by him.
Chen was obsessed with disassembly because of his desire for the essence of things, which made him learn a lot of knowledge at a young age.
After going to school, his understanding of knowledge is much more thorough than that of his peers, which makes his academic performance always among the best.
200 1, Chen Tianhan was sent to Zhengzhou No.1 Middle School because of his excellent grades.
High school study is no longer just book knowledge, but a lot of scientific experiments, which makes Chen Tianhan excited.
Every experiment, he is obsessed with it, and because of his strong hands-on ability and deep thinking, he is deeply liked by teachers and classmates.
Gradually, he integrated what he learned into his life, not only taking things apart, but also assembling them completely.
One day, Chen Tianhan went to grandpa's house for dinner with his parents.
At the dinner table, my parents were still nagging him about unpacking, when grandpa suddenly remembered something.
I saw my grandfather take out an old radio and said to Chen Tianhan, "This radio has been with me for more than ten years, but it suddenly broke down a while ago. Don't you like playing with this thing? Can it be repaired? "
Without further ado, Chen Tianhan put down the bowl and began to disassemble the radio. In a short time, he repaired the radio. Grandpa was very happy and praised Chen Tianhan for his good skills.
My parents saw Chen Tianhan coax grandpa so happy that they let him go.
In the Spring Festival of 2002, Chen Tianhan's uncle and his family came to their house for dinner. The family is happy.
At some point, my uncle found that the mobile phone was dead, so he asked Chen Tianhan to bring the charger at home.
But the interface shape of the charger doesn't match at all, and uncle's mobile phone still can't charge.
At this time, my uncle got a little angry and began to complain to my aunt: "I told you to hurry up, I didn't bring my charger." What if someone asks me? "
Aunt was a little angry: "you don't take your things well, but you blame me." It's better not to look for you, so that you don't have to go out to play cards and lose money. "
Seeing that the two were about to quarrel, Chen Tianhan quickly borrowed a suitable charger from his neighbor to solve the problem.
After this incident, Chen Tianhan thought: "Why not study a charger suitable for all mobile phones?"
When he told his father the idea, his father thought he was dreaming.
What dad didn't know was that it was this whimsical idea that really changed Chen Tianhan's life.
Seeing that his father didn't support him, Chen Tianhan was ready to teach himself.
He used the pocket money he usually saved to buy various brands of chargers, and repeatedly disassembled them to study the mystery.
Every weekend, he will consult a lot of relevant information and then disassemble the charger.
If you don't understand, write it down and ask the physics teacher at school.
The physics teacher likes this curious child very much, so every time Chen Tianhan asks a question, the teacher will help him answer it attentively.
Soon, Chen Tianhan understood the working principle of the charger.
The charger converts high-voltage direct current into the voltage required by the mobile phone through triode and transformer.
But mobile phone chargers are incompatible. In addition to the different data ports, the most important thing is that the internal voltage of the charger is different.
How to solve the voltage conversion between mobile phones? This is such a difficult question that even the physics teacher can't give him the answer he wants.
Chen Tianhan knows that if this problem can't be solved, all his thoughts are looking at flowers in the fog and looking at the moon in the water.
Until one day, my mother came home from work and found that the flashlight was broken and wanted to change the battery.
The moment Chen Tianhan watched his mother pour out the battery, it suddenly dawned on him that the mobile phone battery can also be disassembled. If you put the research point on the mobile phone battery, will there be unexpected gains?
He began to observe different models of mobile phone batteries and draw the orientation of the metal contacts of each charger.
After drawing hundreds of mobile phone metal contact points, Chen Tianhan finally concluded: "Although the distance between battery contact points is different, the positive and negative poles have not changed much."
This subtle discovery sobered him up. If you design a device that meets all mobile phone contacts, then all batteries can use one charger!
Soon, Chen Tianhan designed a rough outline, clamped the battery with a clip, and then pressed two metal contact pins that can be adjusted left and right above the clip.
According to the position of the battery contact point, the contact pin is adjusted to the appropriate positive and negative poles, which truly realizes the problem of charging different mobile phones.
After half a month, he finally developed the first universal charger. Although the image of "animal trap" is a bit strange, Chen Tianhan is still full of confidence in it.
After many experiments, its practicability and safety were finally ensured, so Chen Tianhan submitted a patent application to the Intellectual Property Office and obtained the patent qualification as he wished.
In September 2003, Chen Tianhan won the first prize of "18 National Youth Science and Technology Innovation Competition" for this invention.
In June of the same year, 5438+ 10, the universal charger was introduced to the market, which quickly attracted people's buying.
I found that no matter what kind of mobile phone, the battery will be recharged in just a few hours.
So, everyone gave it a new name, called "universal charging".
Chen Tianhan won the first bucket of gold in his life by virtue of "universal charging". He just turned 18 years old that year.
18 years old, often easily tempted by secular interests when young.
People around Chen Tianhan are worried about him, afraid that he will get carried away.
But soon, the family found that this kind of worry was unnecessary, and Chen Tianhan still followed his own pace.
During the day, he studies hard, hoping to be admitted to the university in his mind; In the evening, I am committed to improving the shortcomings of "universal charging".
It is this brave practice and pragmatic style that enabled Chen Tianhan not only to win the market, but also to walk Tsinghua.
It is puzzling that after Chen Tianhan was sent to Tsinghua, he studied journalism instead of physics.
When the physics teacher in senior high school heard the news, he was both happy and sad for him.
But Chen Tianqi doesn't feel sorry. He likes to open things and write articles.
In the fifth grade, his article was published in key journals of Henan Province. 16 years old, won the second prize of the provincial essay competition.
He said to his parents, "Before 18 years old, I shut myself in my room and studied everything around me;" After 18, I want to go out of this house and see the difference in the world. "
Chen Tianhan, who went to college, still worked as hard as in the past, but focused on his studies.
No one would have thought that this ordinary-looking young man would be the founder of Universal Charging.
However, the myth of "omnipotent" did not last long.
In 20 10, iPhone4 became popular all over the world. The unique design has made major brands follow suit, and the integrated body and non-removable battery have become the mainstream.
Later, with the popularity of Android system, major manufacturers integrated the market and the mobile phone interface became unified.
At this point, "universal charging" lost its market advantage and was gradually replaced by charging treasure and withdrew from the market.
Chen Tianhan, the founder of Universal Charging, has already been psychologically prepared, returned to dullness and started a new journey.
After graduating from undergraduate course, Chen Tianhan worked in mainstream media such as Sohu and People's Daily, and later served as the head of several companies.
Today, Chen Tianhan works for HNA Group and is responsible for brand communication.
Maybe his future life won't be as dazzling as in 2003, but now the quiet life makes him happier.
Some people may say that Chen Tianhan is also a representative of "going to Zhong Yong". Although there have been dazzling moments, you can still get lost in the passage of time.
But in fact, at the end of this world, everything will be ordinary.
It's too cold at the top of the mountain, so people always have to come down from the top and enjoy an ordinary life.
Zhou Zeng said: "Life grows three times, once when you find that you are not the center of the world, twice when you find that you are powerless, and three times when you accept and enjoy the ordinary."
People always feel sorry for the "fall" of genius, but no one ever thinks that genius has its own rhythm, and even daily necessities can appreciate the joy of life.
Once great, wonderful and successful will pass, and only by living a good life will life be complete.
Life is a cycle, from obscurity to blockbuster, from being envied to returning to normal.
When you see the reality clearly, stop demanding perfection and miss the past, life will be less anxious and tangled.
Just like Chen Tianhan, he is learning and making progress, and never cares about other people's eyes, because he knows that a smooth and steady life is the most valuable.
The best future is not to live in the glory of the past, but to find your own future and really love it.
After all, if you are not arrogant and impetuous, you can clearly understand your heart; Only by knowing the ordinary can we enjoy life.
