(1) Relevant documents and materials
For example, prior patent documents, documents, periodicals, drawings, etc. Similar to or similar to the application project. When applying for a patent for invention in China, it's best to search for the patent in advance, otherwise the applied project will be easily rejected in the application review process.
(2) Written technical data
1, the technical field and application scope of the application project, and the technical measures, technical means, methods or ways to achieve the same or similar effects as the application project in the existing technology;

In addition, at least one specific example of the applied project should be provided (the specific example here does not refer to the model or the physical object, but refers to the drawings and text descriptions showing the specific example. Only when the technical measures of the application project cannot be explained by drawings and words can models or objects be provided to explain the application theme).
The drawings provided shall be drawn on A4 paper with a carbon pen, and there shall be no words, border lines, dimension line and size labels on the drawings. All parts and components can be marked with numbers (1, 2, 3 ...), and the name of the part represented by each label should be written on another piece of paper.
4. The experimental data and results of the application project, or the phenomena generated in the experiment;
5. With specific examples and practical (trial) conclusions, objectively explain the advantages and disadvantages of the invention. If there is no experimental data or conclusion, the inventor shall objectively analyze the invention and infer the possible advantages and disadvantages of the invention;
6. Differences in technical characteristics between the application project and the existing technology considered by the inventor;
