Zheng Jin usually has strong hands-on skills and is full of curiosity about many things. Once, while his family was away, he took apart the TV set. His parents were shocked, but this child was very curious. Restore the TV soon. His father was a machine maintenance worker in a factory. He once invented a lifting desk, obtained the patent and sold it to a company in Gaochun, earning a considerable income. The father's habit of thinking diligently has a direct impact on his children. In addition, the school's teachers often provide students with opportunities to make small science popularizations, cultivate students' innovative abilities, and provide a world for children. Zheng Jin invented the cooling straw because children usually like to eat cold drinks in the summer. Once he suddenly thought about how convenient it would be if the drinks did not need to be frozen and the straw could cool down. So he invented a straw to store liquid, which could be used to drink drinks after freezing, achieving a cooling effect and ensuring the original taste of the drink. (Any invention is inseparable from inspiration, and children’s innocent questions and ideas that ordinary people think are “whimsical” are often priceless treasures for inventors. , the source of creation. One day in 1821, a peasant girl in Germany was playing with her mother's wooden comb at the door. She came up with a new trick:
She found two pieces of paper. , put it up and down on the wooden comb, put it to my lips, and unexpectedly, it made a "wu-li-wu-li" sound. By chance, a musician named Bushman passed by.
He was attracted by the wonderful sound. He watched the little girl's "masterpiece" carefully. After returning home, he combined the pronunciation principles of the little girl's wooden comb, the Chinese ancient sheng and the Roman flute to make the first harmonica. .
Coincidentally, the inspiration for the invention of the stethoscope also came from children. Once, the French doctor Reneke went to see a woman with a heart disease. The patient was too obese and could not be detected by percussion. Accurate heart rate, but it was inconvenient to put his ear directly on the patient's chest to auscultate. On the way home, Reineke saw a group of children scratching the end of a log with a needle. ,
And another group of children put their ears to the other end of the log to listen. Out of curiosity, he came forward and put his ears to the log to listen. Hearing the sound at the other end of the log! This incident inspired Reineke.
Soon, the stethoscope was invented by the American Rand, and he was reminded to conduct this research. But it was his little daughter. On this day, Rand and his daughter went to the park to play. After taking many photos of his daughter, the child eagerly asked his father for photos. What about the requirements? Rand spent many years studying the problem of disposable imaging, and finally succeeded in developing a disposable imaging camera in 1947. The African American Biko was an extraordinary skill. Mechanic. His son was a newspaper boy, running around delivering newspapers all day long.
The chain on his bicycle was often broken. The son was very distressed by this and hoped that his father could make a new type of bicycle. Kou thought about it repeatedly and made the world's first "two-wheel transmission" bicycle for his children. This kind of bicycle uses the power of the pedal to drive two wheels at the same time, and can travel smoothly on the most rugged trails in the countryside. . Different from the previous ones, Bister, who invented contact lenses, benefited from his son's prank. One day, he was concentrating on reading the newspaper. Suddenly, the glasses on the bridge of his nose were naughty. Little Pete fell to the ground and the lens was broken.
Bister was about to have a seizure when he found that Little Pete picked up the broken lens on the ground, put it against his eyes and looked at it, and suddenly screamed. Bister took a look at the lens and saw a small ant crawling on the ground.
At this time, he had an idea: The broken lens can still see things without the frame. Wouldn't it be more convenient if it was mounted on the eyeball? In this way, contact lenses were born. You see,
Invention is not an unfathomable thing. Many of our "miracles of civilization" today originate from children's creations, needs, whims and discoveries.
In daily life, inventions and creations are nurtured everywhere.
As long as you have a keen heart and a pair of eyes good at discovery, you can also become a small inventor.
