The first step in making a small invention is to determine the object of the invention and consider what problems to study. This is the topic. For teenagers, they should start from their familiar life reality and look for the theme of invention in schools, families and the surrounding life circles.
For example, when you encounter some difficulties in your study and life, you will definitely say, "If only there were something." This 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 ability, and don't dream of impossible inventions. After the genre is selected, the next step is conceptual design.
That is, according to the basic scientific principles and experience, design the form, structure, method and implementation plan of the subject. When conceiving, try to come up with multiple sets of design schemes, and then choose the best structural scheme according to feasibility and practicality.
The scheme is simple, ingenious and easy to use, with the least disadvantages. When the idea is mature, you can start making it.
When making, we should make use of the existing conditions as much as possible and make beautiful works with little or no money. For some technical problems, teachers and parents can be consulted, and sometimes some related manufacturers can be found to help make some parts.
After the small invention sample is completed, it needs to be tested and improved in practice. That is to say, take the work for a period of time, find out the problems in use, and solicit the opinions of parents, teachers and classmates extensively to see if there are any improvements or unreasonable places.
Then, combine the opinions of all parties to improve this small invention. Almost every excellent invention has been "modified".
At this point, you will enjoy the joy of success. Next, you can declare to participate in youth invention and creation competitions at all levels, apply for patents or contribute to newspapers and periodicals.
The application documents mainly include the application form, project description and certification materials provided by the organizing Committee. Among them, the contents of the project description are: how the topic of the invention was discovered, how the invention scheme was designed, and how the invention works were made. How does this invention show 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 graphic materials.
All small invention projects involving medical and health products, new varieties of animals and plants and animals protected by the state must also provide certification materials from relevant departments. Scientific invention is something everyone can do, and it is also an interesting practical activity.
As long as we carefully observe the things around us, be good at discovering and asking questions, boldly explore and practice, and dare to break through the shackles of rules and regulations, we will make innovations and inventions.
