Which inventions were invented by children

Bushman was inspired by a German girl playing with a wooden comb, combining the Roman piano with the Chinese gusheng to invent the harmonica.

Xingkailing 1, the invention of radar by the ultrasonic positioning of bats;

2. Lu Ban invented the saw because of thorns scratching his hands;

3. The wings of flies are "natural navigators", and people imitate it to make "vibrating gyroscopes";

4. Under the inspiration of Penguin, people designed a new type of car "Penguin brand polar off-road vehicle". This kind of car is attached to the snow surface with a wide bottom of the stall and pushed forward with a wheel spoon, which not only solves the problem of polar transportation, but also can drive in muddy terrain;

5. Watt saw the lid of the pot being washed open by steam and invented the steam train;

6. The Wright brothers got inspiration from the little bird to invent the airplane;

7. The submarine was invented and developed inspired by the diving of fish;

8. Dragonflies can produce a different atmosphere from the surrounding atmosphere through the vibration of their wings, and scientists were inspired to invent ***;

9. According to the sharp eyes of the eagle, the eagle eye was invented for pilots;

10. The electronic frog Sun Zhiyan was invented by the inspiration of the frog's eye.

1. The shape of the submarine: the shape of the submarine imitates the whale, which can reduce the resistance of traveling in the water, reduce the noise, and increase the concealment ability; The working principle of the submarine is to imitate the work of a fish bladder.

2. Electronic frog eye: According to the visual principle of frog eye, the electronic frog eye was invented. Electronic frog eyes can identify objects of a specific shape with the same accuracy as a real frog eye.

After the electronic frog eye is installed in the radar system, the anti-jamming ability of the radar is greatly improved. This radar system can quickly and accurately identify specific shapes of aircraft, ships, missiles, etc. In particular, it can distinguish between real and fake missiles and prevent the real from being confused with the real.

3. Radar: Bats use "ultrasound" to navigate at night. The larynx of the bat emits a high-frequency sound wave that is more than the human ear can hear, and this sound wave travels in a straight line and returns quickly as soon as it touches an object, and the bat receives this returning ultrasound wave with its ear, so that it can make accurate judgments and guide the bat to fly.

Radar uses this characteristic to create radar based on the echolocation system of bats with the help of the principle of biomimicry.

4. "Compound eye" digital camera: Scientists were inspired by the structure of bees and flies with compound eyes, and invented a "compound eye" digital camera. This camera hemispherical arrangement of 180 microlenses gives it a 160-degree field of view, enabling it to focus on different depths of objects at the same time.

While the human eye and all cameras use a single lens to focus light onto a light-sensitive tissue or material, an arrangement that produces high-resolution images, the compound eye offers a unique advantage in that it produces a panoramic view of the light and presents a significant depth of sense.

5. Aircraft: The invention of the airplane originated from the human yearning for flight and the study of birds, in modern times, due to the development of aerodynamics and mechanics, people gradually understood the principle of bird flight, because of the shape of the bird's wings, the speed of the air flow through the upper surface of the wing is faster than the speed of flowing through the lower surface, resulting in the upward airflow pressure on the lower wing surface is greater than the downward airflow pressure on the upper surface, this pressure difference is the lift, and thus the aircraft is manufactured.

1. Fu Xi, who is good at observing natural phenomena, was inspired by spiders making webs to catch flying insects, so he invented the net and taught the tribal people to use it to fish and hunt, and also taught everyone to domesticate the sacrifices that could not be eaten.

2. Lu Ban paid great attention to the observation and study of objective things, and he was inspired by natural phenomena and devoted himself to creating inventions. Once, when he was climbing a mountain, his finger was cut by a small grass, and he plucked the grass to inspect it carefully, and found that the blades of grass were full of small teeth arranged in an even row, so he imitated the blades of grass to make a saw.

3. Submarines were invented and developed inspired by the diving of fish. A general named Dawei Bushnell and military experts jointly developed a motorized boat that could sneak underwater, and the bottom of the boat made a water tank similar to a fish bladder, with two pumps in the water tank, and when the boat was about to sink on the water, it would fill the cabin with water; When the boat is about to float, the air is pressed into the water tank and the water is discharged from the boat.

At the beginning of the century, the Italian physicist Volt designed the world's earliest volt battery based on the electric fish power generation organ. Because this battery is designed based on the natural generator of electric fish, it is called "artificial electric organ". The study of electric fish has successfully mimicked the power generation organs of electric fish.

5. Watt was inspired by water vapor to invent the steam engine. He observed that as soon as the water boiled, the steam in the pot would come out, pushing the lid to jump. The steam kept rising and the lid of the pot kept jumping, as if there was a magician hiding inside.

Watt finally figured out that it was the water vapor that pushed the lid to beat, and later invented the steam engine.

6. Scientists were inspired by dragonflies to develop helicopters. When flying at high speed, the aircraft often causes violent vibrations, and sometimes even breaks the wings and causes plane crashes. Dragonflies rely on their weighted wings to fly at high speeds, so people imitate dragonflies by adding counterweight bridges or hammers to the wings of airplanes, solving the thorny problem of vibrations caused by high-speed flight.

1. Edison was inspired by the heat of bamboo silk and invented the electric lamp;

2. The Wright brothers were inspired by birds to invent the Changshi airplane;

3. Lu Ban was inspired by thatching and mowing people and invented the saw;

4. Watt was inspired by the steam to lift the lid of the pot and invented the steam excitation machine;

5. James Hargming Pure Revos was inspired by the knock-down spinning wheel and invented the Jenny loom.

1. Inspired by bats, radar was invented.

Bats emit a kind of ultrasound that comes back when it encounters an object, but humans can't hear it. Radar was invented based on this property of bats. Radar is used in a variety of places, such as airplanes, aviation, etc.

2. The inspiration of the electric fish invented the voltaic battery.

Electric fish have a peculiar power generating organ in their body. These power-generating organs are made up of translucent, disk-shaped cells called plates or disks. It is designed according to the natural generator of electric fish, so it is called "artificial electric organ".

3. Inspired by termites, he invented dry rubber cannonballs.

Not only do termites use adhesive to build their mounds of dirt, but they can also spray adhesive at enemies through the small tubes in their heads. So people made a working ** according to the same principle - dry rubber shells.

4. Shinkansen trains.

Shinkansen trains were originally designed to simulate bullets, and they were successful. But there is a problem with this design, which is that they make loud noises when they leave the tunnel. Eji Nakatsu, an engineer at Shinkansen Train Design Company, applied the beak shape of the kingfisher to the train design, which not only solved the noise problem, but also increased energy efficiency and improved the top speed.

5. Adhesive tape. Scotch tape was invented by Richard Gurley Drew in 1922. He was a lab technician at 3M who was delivering sandpaper samples to a local car shop when he heard clerks often complain about the tape marks left when painting Cong's car.

Over the next two years, he experimented with a variety of adhesives to find a way to remove the tape without leaving a mark, which eventually led to the introduction of Scotch tape. Geckos in nature are able to climb surfaces with the help of tiny bristles at the base of their toes.
