1. How to make small inventions that save money!
Wrap the beer bottle caps with rags, and then sew them together according to the shape you want. It can be made into a glove box or a coaster; put the unused straws in the shape you want. It is required that it can be worn into curtains and partitions; the packaging boxes for refrigerators, TVs and other large appliances can be used to make simple furniture such as small bookcases, bedside tables, CD racks, etc. As long as you are a thoughtful person in life, pay attention to everything...
2 When I am at home, I always take the initiative to do whatever I can do, such as washing dishes, mopping the floor, wiping the table, etc. The thing I fear the most is mopping the floor. I got blood blisters on my hands after mopping a few rooms. Cabinets, tables and other narrow places are not easy to mop, and they cannot be mopped clean. Once, while mopping, I thought, it would be great if I had a pair of mop shoes that I could wear on my feet to mop the floor! So, I designed a mopping tool that is both light and does not bend over - shoe slippers.
Preparation method: 1. Shoe slippers are larger than the shoes you usually wear, so they are easy to put on your shoes.
2. Use rag strips as mop strips on the soles of the shoes, and nail a thicker plastic bottom on the mop strips, which is both waterproof and durable.
3. Use cloth shell and waterproof cloth to make the shoe upper, and install a zipper on the back of the shoe upper to make it easy to put on and take off. Connect the upper and sole to make the slippers.
Completing a small invention is not as simple as "furrowing your brows and thinking about it". It needs to go through steps such as topic selection, conception and design, production, practical testing and improvement, and success.
The first step in making a small invention is to determine the object of the invention and consider what problem to study. This is topic selection. For teenagers, they should start from the reality of life they are familiar with and look for creative themes in school, family and surrounding life circles. For example, when you encounter some difficulties in study or life, you will definitely say: "It would be great if there was such-and-such a thing." The thing you want to invent can be used as the object of invention. However, when choosing a topic, students must combine their own knowledge level and design and production capabilities, and do not dream up inventions that are impossible to achieve.
After the genre is selected, the next step is to conceive and design. That is, based on basic scientific principles and experience, the form, structure, method and implementation plan of the topic object are designed. When conceiving, try to come up with as many design plans as possible, and then select the best structural plan based on feasibility and practicality. It is better to use simple materials, be clever and easy to implement, and have the least shortcomings.
After the idea is mature, you can start production. During production, existing conditions should be used as much as possible to produce exquisite works with little or no money. For some technical issues, you can ask teachers and parents for advice. Sometimes you can also find relevant manufacturers to help make some parts.
After the small invention sample is completed, it needs to be tested and improved in practice. That is, use the work for a period of time, discover problems during use, and solicit opinions from parents, teachers, and classmates to see if there are any improvements or unreasonable areas. Then, the opinions from all aspects are combined to improve the small invention. Almost every excellent little invention is "modified".
At this point, you will enjoy the joy of success. Next, you can apply to participate in youth invention and creation competitions at all levels, apply for patents, or submit articles to newspapers and periodicals. The application documents for the competition mainly include the application form, project description and supporting materials provided by the organizing committee. Among them, the project description content is: how is the topic of the invention discovered, how is the invention plan designed, and how is the invention work produced? How does this invention demonstrate novelty, creativity and practicality? What is your creative contribution? Suggestions and ideas for further improving the invention. Attach appearance drawings (preferably black and white photos), structural drawings, schematic diagrams and other necessary diagrams and information. Any small invention projects involving medical and health care products, new varieties of animals and plants, and nationally protected animals and plants must also provide certification materials from relevant departments.
Scientific inventions are something that everyone can do, and it is also an interesting practical activity. As long as everyone carefully observes the things around them, is good at discovering and asking questions, boldly explores, hands-on practice, and has the courage to break through the constraints of rules and regulations, there will be innovations and inventions.
