invention and technology

The following are some small technological products related to aerospace inventions: 1. ** Self-made air powered rocket in a beverage bottle ** - [Materials: Drink bottle, scissors, straw, crayons, white paper, glue gun.] - Steps: - He drew two rockets on a piece of white paper, colored them, and cut them out for future use. - He used a glue gun to seal one end of the straw, then stuck the two rockets and the straw together (without a glue gun, he could use tape to stick them together). - Drill a hole in the center of the bottle cap, pass the straw through the hole, and stick a piece of paper at the bottom of the straw (it's best for Mom and Dad to do the drilling). - He put it into a bottle and screwed the cap on, and a simple aero rocket toy was ready. - "Scientific principle: With compressed air as the driving force, the rocket will be pushed upward due to the recoil effect. The entire process is to use compressed air to store energy and then release it instantly to push the arrow upward. 2. ** An aerospace scene model made of cardboard boxes ** - Materials: Milk carton, black cardboard, lake blue, indigo blue, purple and other colors, pen, sticky paper tube, hard cardboard, colored paper, colored light clay, small light strip, five-star red flag sticker (can be drawn). - Steps: - He cut open one side of the milk carton, cleaned the inside and the edges, took out a piece of paper to reinforce the bottom, covered the bottom with two pieces of black cardboard, squeezed in lake blue, indigo, purple, and other colors, and used a brush to draw a mysterious starry sky background. After thinning the white paint, he scattered a starry sky. - He used the sticky paper tube and cardboard at home to make three cylinders. He cut a round piece of paper to make the rocket head and drew a five-star red flag. He cut out three pieces of colored paper to make a flame. The rocket was completed and glued to the lower right corner. - A sun was formed by rubbing colored light clay, and a thin thread was used to fix it on the top of the box. Clouds were cut out from colored paper to decorate the box. - He also placed the light soil astronauts on the ground, poked a hole in the back, and stuck the small light strips into the tape to secure them (multiple light strips can be used according to needs and the wires can be laid). 3. ** Solar Satellite Model ** - [Materials: Solar satellite model technology, small production, small inventions, aerospace, hand-assembled toy material bag (contains the relevant components, pictures, instructions, video tutorial, etc. for making satellites).] - Steps: - According to the pictures, instructions, and video tutorial, the fixed motor was connected to the solar panel. - After the assembly was completed, it could be doodled and colored. In a sunny environment, the two solar panels on the top would convert the light energy of the sun into electricity and then feed it to the motor. The motor would start to rotate the satellite.

Changdian Technology obtained a number of invention patents, such as the patent named "packaging structure and packaging method". Its patent application number was: <anno data-annotation-id ="233334418 - 4550 - 4410 - 8530 - 8555333.1"></anno>, and the authorization date was November 8, 2024. The chip in the packaging structure is located on the component area, the elevating structure is located on the shielding area, the elevating structure is connected to the ground connection area and is insulated from the non-ground connection area, the shielding lead wire is connected to the top of the elevating structure on both sides of the chip and is located above the first lead wire, so that the two will not be contacted and short-circuited. At the same time, the shielding lead wire is connected to the ground connection area, which can play a role in shielding the chip during operation. The electromagnetic shielding effect is good, and the size of the packaging structure is small by using the shielding lead wire as the shielding layer. Low cost. Changdian Technology also obtained an invention patent entitled "Multi-layer circuit board and its offset detection method." The patent application number was: <anno data-annotation-id ="00000000 - 4110 - 4250 - 8000 - 901100000"></anno></anno>, and the authorization date was April 12, 2024. The deviation detection method is to form a circuit layer containing a specific monitoring pattern, conduct the conducting pattern to form an electroplated layer, and judge whether the deviation between the layers of the multi-layer circuit exceeds a predetermined value according to whether the electroplated layer exists on the surface of the reference pattern, so as to judge whether the multi-layer circuit base plate is qualified or not, greatly simplify the deviation monitoring process, and improve the yield of the client products. In addition, Changdian Technology obtained a patent named "Chip Stripping Assembly and Chip Stripping Device". The authorization announcement number was CC114496834B, and the application date was November 2020. The novel "Sitting and Watching Immortals" is equally exciting.

Sure, the invention of the GPS (Global Positioning System) is a remarkable success story. It was initially developed for military use but later became available for civilian applications. GPS has transformed the way we travel. Whether it's for driving, hiking, or flying, people can accurately find their way around. It's integrated into many devices like smartphones and car navigation systems, making it extremely accessible. This has led to the growth of location - based services such as ride - sharing apps that rely on accurate location information.

Sure. The story of the smartphone is quite interesting. It combined multiple technologies like communication, computing, and photography. Companies like Apple and others worked on making these devices compact and user - friendly, revolutionizing how we access information and interact with the world.

The following are some of the inventions related to aerospace: 1. Tethered satellites: Inspired by kites, aerospace scientists invented tethered satellites. They were connected to space shuttles, spaceships, or space stations by ropes or chains. They could be launched or recovered at any time to capture electrical energy in space, which was difficult for ordinary satellites to accomplish. 2. [The word 'aerospace' was invented by Qian Xuesen.] Although his report to the central government from the United States was about the aerospace industry, the actual content was about missiles, rockets, satellites, and other aerospace matters. Inspired by Chairman Mao's poem,"Looking at a thousand rivers from afar," Qian Xuesen used the word "sky" to represent the universe and invented the word "aerospace." 3. ** Civil invention derived from aerospace technology ** - ** Freeze-dehydrated vegetable technology **: Originated from the Apollo program of the United States, it was developed to solve the problem of astronauts eating vegetables to supplement vitamins. Later, it was widely used to make dried vegetables and dried fruits. - ** High-efficiency diapers **: invented by Chinese engineer Tang Xinyuan of NASA in the 1980s. It was originally used to solve the problem of astronauts going to the toilet in space. Later, it was transferred to civilian use to reduce the production cost of diapers. - ** High-efficiency water purification system **: developed by NASA, including iodine-based disinfection and silver-copper alloy disinfection technology. It is now widely used in urban tap water purification. - Memory cotton (space memory pillow material): Used on the space shuttle to relieve the pressure of astronauts and protect the spine. It was developed as a civilian (medical) product in the early 1990s. 4. Since 2010, China has actively expanded the civilian use of aerospace technology. More than 2000 aerospace technologies have been converted to civilian use. For example, the market share of friction stir welding equipment has exceeded 50% and the production line has been imported overseas. The carbon fiber composite technology has led the development of lightweight vehicles to help the development of new energy vehicles. The novel "Hundred Years of Spaceship" is equally exciting.
