when designing electronic products, the European union requires businesses to strengthen the interchangeability and disassembly of batteries.
when people read this report, they suddenly felt as if they had been separated from each other.
does it mean that the era of "universal charging" is about to return when the battery becomes detachable?
When it comes to "omnipotent", many young people may have no idea now, but it is an unforgettable memory for those born in 198s and 199s.
the price of more than ten pieces, two adjustable metal pieces, a fixed transparent clip and a base with a plug are such a "humble" device, but it is an epoch-making product.
Back in those days, "universal charging" helped countless people solve the problem of mobile phone life, and at that time, almost everyone had one.
However, few people know that Chen Tianhan, the inventor of this popular universal charger, was just a high school student who just turned 18.
In p>1985, Chen Tianhan was born in an ordinary family in Zhengzhou, Henan Province.
when he was young, he was full of curiosity about the world, and he always wanted to get to the bottom of everything.
When he grows up, he begins to do it himself. Anything that can be disassembled must be taken apart and studied.
At first, Chen Tianhan just took apart his toys. The newly bought toy was torn apart by him in an instant.
Mom was furious when she saw the parts everywhere. "Why did you tear them down again? I won't buy them for you in the future."
every time, he promised not to, but after buying a new toy, he still did.
As he grew older, Chen Tianhan began to dismantle his toys, and his eyes fell on furniture and electrical appliances.
The newly bought sofa was cut by him with a knife, just to find out what was in it and why it was so comfortable.
I don't know how many watches he removed from the wall, just because he wanted to try and see if he could put them back.
This kind of destructive behavior made parents unbearable, but Chen Tianhan still went his own way.
In desperation, his parents had to make an agreement with him in three chapters: only tear down old things, not new ones; Only dismantle the cheap ones, not the expensive ones; Only the simple ones, not the complicated ones.
Seeing his parents' concession, 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 "harmed" by him.
Chen Tianhan is obsessed with disassembly because of his desire for the essence of things, which makes him learn a lot of knowledge at a young age.
After school, his understanding of knowledge is much more thorough than that of his peers, which makes his academic performance always among the best.
In p>21, Chen Tianhan was sent to Zhengzhou No.1 Middle School because of his excellent grades.
Learning in senior high school is no longer just book knowledge, but a large number of scientific experiments make Chen Tianhan excited.
Every experiment, he was fascinated by it, and because of his strong hands-on ability and deep thinking, he was deeply liked by teachers and classmates.
gradually, he integrated what he had learned into his life, not only taking things apart, but also assembling them intact.
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 things, when Grandpa suddenly remembered something.
Grandpa took out an old radio and said to Chen Tianhan, "This radio has been with me for more than ten years, but it suddenly stopped working a while ago. Don't you like tinkering with this thing? Can you fix it?"
Chen Tianhan put down the bowl without saying a word, and began to disassemble the radio. In just a moment, he repaired the radio. Grandpa was so happy that he praised Chen Tianhan for his skill.
When my parents saw Chen Tianhan coaxing Grandpa so happily, they let him go.
In the Spring Festival of p>22, Chen Tianhan's uncle and his family came to their house for dinner. The whole family was very happy and lively.
At some point, my uncle found that his 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 my 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 asked you to hurry, and I didn't take my charger. What can I do if someone asks for me?"
Aunt was a little angry when she heard this: "You don't take your things well, but you blame me. It's better if you can't be found, so you don't have to go out to play cards and lose money."
Seeing that they were about to quarrel, Chen Tianhan quickly borrowed a suitable charger from his neighbor, which solved the problem.
After this incident, Chen Tianhan thought, "Why don't you study a charger that is suitable for all mobile phones?"
when he told his father this 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.
Chen Tianhan saw that his father didn't support him, so he prepared to study it himself.
With his pocket money, he bought various brands of chargers and disassembled them repeatedly to study the mystery.
every weekend, he will consult a lot of relevant materials, and then disassemble and assemble the charger.
if you don't understand something, write it down and ask the physics teacher at school.
The physics teacher likes this eager child very much, so every time Chen Tianhan asks questions, the teacher will help him with his heart.
Soon, Chen Tianhan understood the working principle of the charger.
chargers convert high-voltage direct current into the voltage required by mobile phones through triodes and transformers.
However, different mobile phone chargers are not compatible. Apart from the differences in data ports, the most important thing is that the internal voltages of the chargers are different.
how to solve the voltage conversion between mobile phones? This is such a tough 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 flowers in the fog and the moon in the water.
until one day, when my mother came home from work, she found that the flashlight didn't work and wanted to change its battery.
The moment Chen Tianhan watched his mother pour out the battery, he suddenly had an epiphany: the mobile phone battery can also be disassembled. If the research point is placed on the mobile phone battery, will there be unexpected gains?
He began to observe different models of mobile phone batteries and drew the orientation of the metal contact points 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 made him awake. If you design a device that meets the contact points of all mobile phones, 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, adjust the contact pin to the appropriate positive and negative poles, so that the problem of charging different mobile phones can be truly realized.
after half a month, he finally developed the first universal charger. Although the image of the "animal trap" is a bit strange, Chen Tianhan is still full of confidence in it.
after many experiments and argumentation, 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 p>23, Chen Tianhan won the first prize of the 18th National Youth Science and Technology Innovation Competition with this invention.
in October of the same year, the universal charger was introduced to the market, which quickly attracted people to snap up.
people find 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 Charge".
Chen Tianhan won the first pot of gold in his life by virtue of "universal charge", and he just turned 18 that year.
at the age of p>18, when you are young, you are often easily tempted by worldly interests.
People around Chen Tianhan are worried about him, afraid that he will get carried away.
But soon, the family found that this worry was unnecessary, and Chen Tianhan still kept on moving at his own pace.
During the day, he studies hard, hoping to be admitted to his university. In the evening, I devoted myself to improving the shortcomings of "Universal Charge".
It is this brave practice and pragmatic style that makes Chen Tianhan not only win the market, but also get the qualification of walking in Tsinghua University.
It is puzzling that after Chen Tianhan was recommended to Tsinghua, he studied journalism instead of physics.
When the physics teacher in senior high school heard the news, he was both happy and sorry for him.
But Chen Tianhan doesn't feel sorry. He likes to disassemble things and write articles.
In the fifth grade, his articles were published in key journals in Henan Province. At the age of 16, he won the second prize in the provincial essay contest.
He said to his parents, "Before I was 18, I shut myself in my room and studied everything around me. After I am 18 years old, I want to go out of this house and see the difference in the world. "
Chen Tianhan, who was in college, still worked as hard as before, but put his focus on disassembly on his studies.
No one would have thought that this ordinary-looking young man would be the founder of "Universal Charge".
However, the myth of "omnipotent" did not last long.
in p>21, the iPhone4 became popular all over the world, and its unique design made major brands follow suit, and the integrated body and non-removable battery became the mainstream.
After that, with the popularity of Android system, major manufacturers integrated the market, and mobile phone interfaces 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 "creator of omnipotent power", had already been psychologically prepared, returned to dullness and started his 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 will not be as dazzling as it was in 23, but the quiet life now makes him happier.
Some people may say that Chen Tianhan is also a representative of "Shang Zhongyong". Although there has been a dazzling moment, it can still be lost in the passage of time.
but in fact, everything in this world is going to be ordinary.
it's too cold at the top. People always have to come down from the peak and enjoy an ordinary life.
Zhou Guoping once said: "Life grows three times, one is when you find yourself not the center of the world, the other is when you find yourself powerless, and the third is 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, even if the daily necessities are trivial, they can appreciate the joy of life.
once great, wonderful and successful will pass, and only by living a good life can 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 your 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 worth cherishing.
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, only by not being arrogant can you know your heart clearly; Only when you know the ordinary can you enjoy life.
