What inspired the invention of refrigerator?

Bat: Radar. Fly: A spaceship. Frog: electronic frog eyes. Police dog: electronic police dog. Pig nose: gas mask. Ships and submarines are modeled after fish and dolphins. Scientists have made the first batch of gas masks in the world according to the unique drug detection ability of wild boar nose. The rocket takes off by using the recoil principle of jellyfish and squid. Researchers have developed many military camouflage equipment for the army by studying the chameleon's color-changing ability. Scientists studied frog eyes and invented electronic frog eyes. The US Air Force has developed a miniature thermal sensor through the "hot eye" function of poisonous snakes. Humans also used the principle of leapfrog to design a toad ram (hang). Humans imitate the highly sensitive sense of smell of police dogs and create "electronic police dogs" for investigation. Bionic and high-tech modern radar-a radio positioning and ranging device: Scientists have found that bats rely not on eyes, but on an echo positioning system consisting of mouth, throat and ears. Because bats emit ultrasonic waves when flying, they can also detect ultrasonic waves reflected by obstacles. Based on this, scientists have designed a modern radar-a radio positioning and ranging device. By studying the tiny swimming resistance of dolphins, scientists invented an artificial dolphin skin that can improve the speed of torpedoes. And a wheeled vehicle (jumping machine) that imitates kangaroo's movement in the desert. Inspired by penguins, scientists from the Institute of Zoology of the former Soviet Academy of Sciences designed a new type of car-Penguin brand polar off-road vehicle. The wide bottom of this car is directly attached to the snow surface, supported by a wheel spoon, and the speed can reach 50 km/h. Scientists make space robots by imitating insects. A research team of Australian National University has developed a small navigation and flight control device by studying several insects. This device can be used to equip a small aircraft for Mars exploration. Inspired by bionics, British scientists are developing a new submarine, which can swim in an S shape by swinging its tail fin. The main innovation is the use of a device called "trunk actuator". "Elephant trunk" consists of a group of thin and soft hoses, which imitate muscle activity and promote fin movement. This new submarine can be used as an underwater mine-clearing submarine to deal with mines that will detonate at the slightest sound or interference. (China National Defense News) A teacher invented a hexagonal desk. The students praised it as "endless fun". Chen Dong Farming is a young teacher in Ningbo. He replaced the traditional rectangular desk with a hexagonal desktop. Chen Dong said in an interview that the idea of designing this new desk was inspired by bionics theory. In nature, the hexagonal honeycomb structure is unique, and the hexagonal snowflakes have different shapes ... After the desktop of the desk is transformed into a hexagon, the combination is flexible, the appearance is pleasing to the eye, the limited space can be effectively used, and the classroom atmosphere is active, which is welcomed by students. Now all classes in Zhicheng school and primary school are fully promoting the use of hexagonal desks. Responder: Kuai 1 Xia-Trainee Magician Level 3 3-28 20:28 Human Invention-Inspired by Animals 1. A strange small gas analyzer, which was successfully copied from annoying flies.

This kind of electronic frog's eyes can accurately identify objects with specific shapes like real frog's eyes. After installing electronic frog eyes in radar system, the anti-jamming ability of radar is greatly improved. This radar system can quickly and accurately identify aircraft, ships and missiles with specific shapes. In particular, it can distinguish between true and false missiles and prevent false confusion. Electronic frog eyes are also widely used in airports and traffic arteries. At the airport, it can monitor the take-off and landing of aircraft, and call the police in time if it is found that the aircraft is about to collide. On the main road, you can direct the vehicles to prevent them from colliding. 6。 According to the principle of bat ultrasonic locator, people also copied "Pathfinder" for the blind. This pathfinder is equipped with an ultrasonic transmitter, which blind people can use to find telephone poles, steps, people on bridges, etc. Nowadays, "ultrasonic glasses" with similar functions have also been made. 7。 By simulating the incomplete photosynthetic mechanism of cyanobacteria, a bionic photolysis device was designed to obtain a large amount of hydrogen. 8。 According to the study of human skeletal muscle system and bioelectricity control, a human strength enhancer-walking machine is copied. 9。 The hook of modern crane originated from the claws of many animals. 10。 Corrugated roofs imitate animal scales. 1 1。 Paddles imitate the fins of fish. 12。 Saw mantis arms, or saw grass. 13。 The plants of Xanthium were inspired to invent velcro. 14。 Lobster with keen sense of smell provides people with the idea of making odor detectors. 15。 Gecko toes provide an encouraging prospect for manufacturing reusable adhesive tape. 16。 The colloid formed by shellfish and protein is very strong, and this colloid can be used in everything from surgical suture to ship repair. 17。 People have successfully designed an accurate "jellyfish ear" instrument by simulating the organs of jellyfish that feel infrasound waves. It consists of a horn, a resonator for receiving infrasound waves, a transducer for converting this vibration into electric pulses and an indicator. This instrument is installed on the front deck of the ship, and the horn rotates 360. When it receives 8 Hz- 13 Hz infrasound, the rotation stops automatically, and the direction indicated by the horn is the coming direction of the storm. Indicators can also tell people the intensity of the storm. This instrument can forecast storms 15 hours in advance. 18。 The compound eyes on both sides have the greatest influence on the behavior of horseshoe crab. After being irradiated by the light beam, the compound eye produces a pulse. One eye is irradiated by the light beam, and the other eye generates the main pulse; Both eyes are irradiated by light beam at the same time, and both eyes generate pulses at the same time, but the frequency of pulses generated by light beam irradiation on one eye is slightly lower. Inspired by it, mankind has successfully developed an electronic simulation device, which can solve the network equation composed of 10 elements. The TV camera made by applying this principle can provide high-definition TV images under laser. 19。 Not long ago, the bionic research team of Illinois State University developed a set of artificial lateral lines that can give robots a "sixth sense", similar to the lateral line system of fish. This artificial lateral line consists of many tiny silicon wafers arranged on the surface, which are similar to hair bundles, and each silicon wafer is connected to an electronic sensor through a micro chain. When the water flows in contact with the silicon beam, the silicon beam will bend due to the different speed of the water flow, so that the sensor can detect the bending angle and direction of the silicon beam, thus helping the robot find the desired direction. 20。 Albatross is a kind of seabird, and it has an organ that desalinates seawater-a "desalter". The research on the structure and working principle of its "desalter" can inspire people to improve old or create new seawater desalination devices.

During holidays, he often sits in the garden for a while. Once, as happened many times in the past, an apple fell from the tree ... The accidental landing of an apple was a turning point in the history of human thought, which made Newton sitting in the garden open his mind and made him think deeply: What is the reason why almost all objects are attracted to the center of the earth? Newton mused. Finally, he discovered the gravity which is of epoch-making significance to mankind. The origin of compound eye camera The compound eye of insects is made up of thousands of small eyes. Because of the mutual inhibition between small eyes, eyes have the function of highlighting the image boundary and increasing the clarity. People made a "fly eye camera" for scientific research by imitating the honeycomb structure of small eyes in flies' stomachs. You can take 1329 photos at a time with a resolution of 4000 lines. The revelation of nature is: the origin of compound eye camera: the compound eye of insects is composed of thousands of small eyes.
