So, you can follow the youth science and technology innovation activities to broaden their horizons and active thinking. We introduce to you several common theme ideas and creative techniques to make gadgets. I hope your spirit encourages research and writing inspiration, and seriously says: "I can do it!"
What are scientific inventions
Mentioned inventions, how some students are nagging Na is afraid! In fact, inventions are not mysterious. Many high school students’ inventions have won prizes across the country and even internationally!
Scientific inventions are made day by day by young people who learn, live, and labor, and those who are not satisfied with the inconvenience of using their scientific knowledge, design, and manufacturing instead of better and more convenient thing or method new item or new method. It is compared to the present invention, the selected range is relatively narrow, it is relatively simple to solve this problem, the materials used are relatively easy to find funds, and the so-called "small invention" is not used
Novelty and novelty will not appear in the same content or technology products as you complete this gizmo. Meaning you can not buy the same product in front of books, periodicals, radio, television, in shops on the street, without seeing or hearing the description of the same invention, nor by filing an application and filing with the patent office by someone else, but also by no one else Participate in the invention game at all levels, but if you invent new features, new methods, new uses, or original items are cleverly combined to form a new individual addition, adding new functionality to the operator's novelty < /p>
2. Creativity. The gadget has outstanding substantive features and significant improvements compared with similar products
Convenient soap dish
Usually the soap dish is filled with water and soap that will be sticky. , it is not easy to take out the soap and has a short life. Fan Ping, a Tianjin student, used the lever principle to develop a set of convenient soap boxes. When the soap box is opened, the soap will stand up, which is the first technologically advanced product of its kind. First prize in the National Young Inventors Competition.
Practical inventions can be made or used and have a positive effect, not just ideas or design drawings. , and can also solve the problem of production and life.
Pests in Linxian, jujube and fresh jujube are harmful to insects. Liu Yan, a student, carefully observed the growth and activities of jujube insects and found that women climbed up the trunk. Mating with the male damages the leaves and fruits on the tree. He wants to make a semicircular hard plastic plate close to the waist. The inner layer is coated with insecticide cream. Women can do it without the trunk. This simple and ingenious insect-damaged tree skirt is practical and welcome to the majority of jujube farmers. Won the first prize in the 6th National Young Inventors Competition
Of course, completing a small object does not require a frown, it is so simple, it has to go through theme, conceptual design, and production. , practical test, and steps to improve success,
The first step in engaging the present invention is to determine that the purpose of the present invention is, taking into account the problem under study, that the subject matter is for teenagers , The reality should be familiar with life, find inventions around schools, homes and living areas. For example, when you learn some difficulties in life, you will say: "If there are some good things." “You want to invent something that can be used as an invention of an object. However, in the subject, students must combine their own knowledge and design abilities, and not utopias cannot be invented.
Style selection is followed by conceptual design, which is based on basic scientific principles and experience in the design themes of shape objects, structures, methods and implementation plans. Come up with as many ideas as possible to select the best structure for the design, based on feasibility and practicality. Very simple, smart and easy to plan, the disadvantages are at least as good
Once the idea is mature, production can begin, and production should be exploited as much as possible under existing conditions, even if the premise costs less money to make beautiful works. There are some technical issues for teachers and parents to consult, and sometimes you can find some manufacturers to help with certain parts.
A small sample of the invention has been completed, and at the same time for practice and improvement, the testing work will take some time to comment on the problems found in use, parents, teachers and students to see if there is any improvement or Unreasonable and opinions. sides to enhance the gadget. Almost every great invention is a "change".
At this time, you will enjoy the joy of success. Next, you can announce your participation in this competition, establish youth inventions at all levels, apply for patents, or contribute to this newspaper. Participate in the submission of documents, including completion of the organizing committee, project description and certification materials, including: The purpose of the invention is to discover, what kind of design is the method of the invention, and what is the invention? What is your creative contribution that reflects the novelty, creativity and practicality of the invention? Suggestions and ideas for further improving the invention (preferably with black and white photos), additional appearance drawings, block diagrams, schematics, and other necessary data diagrams. Small invention projects involve plant and animal health products, new varieties of animals and plants, and are protected by the state, but evidence must also be provided to the relevant departments.
Science gadgets are something that anyone can do, but there are also fun and endless practical activities, as long as we carefully observe the things around us, be good at discovering problems, ask questions, explore boldly, and practice by hand, Dare to break through the shackles, innovate ideas and invent.
Citing the shortcomings of the gizmo theme and discovering it
To make gizmos in school, we must first learn to choose the topic of the invention.
An important way to learn when life goes wrong is to cite shortcomings and ask: "What shortcomings need to be overcome?" Find a way to overcome them based on the shortcomings of the existing project and the proposed project The idea of ????reforming, the method that lists the shortcomings is also very simple and effective way to choose a small invention
Electric shock socket
Power sockets are available in almost every home, but it is easy Electric shock is especially dangerous for young children, and unplugging can cause a lot of trouble. Xu Chen, a classmate from Shanghai, dissected several traditional power sockets, "Four sockets are protected against electric shock, ordinary sockets and the design of installing thermal insulation roller shutters, power plugs, at the same time, there will be two sockets, power supply, when the child If you don't pay attention to any holes with small hands or nails, the two doors are blocked, and there is no risk of electric shock. This invention won the first prize in the 2nd National Youth Science and Technology Innovation Competition.
What are the disadvantages of the pressure bottle? Due to its outlet, the sediment at the bottom of the bottle is often pushed out by the water pressure and the water becomes turbid. This defect was discovered by Zhang Xueke. To improve the air pressure in the bottle, connect the nozzle to a long rubber tube, and add a plastic float to the nozzle that always floats on the water, so that the air pressure deposits in the bottom of the bottle rather than from the pipette . This invention won the first prize in the Second National Youth Innovation Competition
The invention actually found a shortcoming and was invented to solve the existing problem. Therefore, each of us discovered a shortcoming and proposed it. A question often found in the subject of the invention
How to study and find the shortcomings?
First of all, we should always pay attention to what shortcomings or inconveniences there are to their daily use. Items and good at grabbing an item's precise excavation Umbrellas, sunshades and rain shelters, tools There is nothing in the article that does not seem to resize the inventor to grab it, and keep the pattern updated exclusively for the day, such as umbrellas, double-layered umbrellas, folding umbrellas. , Mother and Umbrella, Quick-drying Umbrella, Umbrella in Astronomy... Endlessly, many themes can be worked on with the same subject matter and various design options can be used to reconstruct the pen, but its disadvantages are still many. , such as the cap is easy to fall off or lost, the tip is not easy to clog, and the round pen is easy to slip.
From table damage to pen nibs, power outages at night or field work, writing invisible... As many shortcomings as possible some items are listed as objects of study, identifying the flaws or deficiencies of the gadget based on the topic you choose. Solar
Inflatable solar cookers are very attractive, but solar cookers have high cost, complicated process, and weight (about 50 kg), trouble to adjust, and inconvenience to carry for field work and travel. Based on the research of Shanghai Xin, the main direction of attack was clarified: simplifying the production process of solar cookers, reducing weight, reducing material consumption, reducing costs, and maximizing power. Expand the inflated parabolic vacuum aluminized polyester self-adhesive film into two circular edges, cover it with plastic, and then stick it on the reflective surface. The foreign cheer pump changes the internal gas pressure, and how much the upper transparent film of cheer extends upward to the concave reflective surface to automatically converge the reflected light can be realized. The baseless inflatable solar cooker only weighs 4 kilograms and is easy to disassemble and assemble. It is easy to carry and won the first prize in the 3rd National Youth Science and Invention Competition.
Inventions are actually the result of various transplantations: inflatable toy technology, from daily necessities trademark patches, lenticular parabolic structures, transplanted to new solar cookers, textbook knowledge, optics, fluid mechanics principles, transplanted to the sun designed a stove and successfully completed a small invention.
Candle lamps are commonly used as lighting tools, but for candles that are afraid of wind and flames, the candle body is not easy to fix and the brightness can be controlled. How to improve these shortcomings? Jianli County middle school students considered fixing Liu Guoxiang in an iron cylinder instead? The wind blew the candle's body into the glass. He believes that a fixed bayonet light bulb, which lends candlelight to the center of the candle's lampshade in the spring, is best positioned to hold the flame.
How to make a candle tear? To solve this problem, we must continue at the top of the candle to lower the temperature and conduct heat to the surroundings. Can the metal radiator of a front-engine car be painted with a lit candle? Soothing lip balm metal box, he drilled a large hole in the shape of the fan sheet will be lowered for good heat dissipation, playing an equally large center hole, cut the heat sink welding (including the alignment of the large hole on the box).
How to control the brightness of a candle flame? The air inlet valve, the gas stove, the trap beam cap (the inner fins are made of tin, the outer plastic ring is made with each other), and the flow of air is controlled by rotating the valve to realize the degree of adjustment according to Zhu Yanliang's wishes. The invention can be said to be a "trickster" complex from a lamp with kerosene, a lampshade, a fixed bayonet light bulb from a heat sink from a car.
It can be seen from the transplantation that the invention is a very important concept. Students have a good grasp and can come up with a cute little invention.
>Key transplanters regularly analyze the main functions or structures of the project in order to expand their knowledge and understanding of new technologies. In this way, the brain is more information available for transplantation, and you can make it easier when you make gizmos.
