What problems should be paid attention to when applying for mechanical patent? If you invent a mechanical product, you must apply for a patent to protect your achievements, but you should know the problem of applying for a mechanical patent. We will introduce this problem through this article. The scope of patent application in mechanical field includes but is not limited to the following aspects: (1) Mechanical devices are composed of certain parts or functional modules, such as machine tools. (2) A complete system or production line is usually composed of multiple devices, such as a plate production line. (3) Mechanical parts whose structure or shape can be improved, such as automobile transmission shafts. (4) Components, functional modules or mechanisms of mechanical equipment that can perform specific functions, such as arc extinguishing devices of circuit breakers. (5) designed or improved products, tools, molds, molds and fixtures, such as internal and external grinding fixture bearings. In addition to products, the improvement of various technological methods in the mechanical field, such as processing methods, assembly methods, detection methods, control methods, construction methods, welding processes, heat treatment processes, casting processes, stamping processes, etc. , can apply for a patent for invention. The patent application in the field of machinery mainly lies in the composition, structure or shape of devices and equipment, so it should provide: 1. Disadvantages of the existing technology/product: it can provide necessary background knowledge to help understand the invention. This paper introduces the brief introduction of the invention, the existing mechanism or device, its main structure and working principle, and points out the shortcomings and structural defects existing in the existing technology. 2. The content of this patent: explain the purpose of this patent or the technical means to solve the problem. With reference to the drawings and reference numerals in the drawings, some related objects of the present invention, as well as the shapes of various parts and their connection relationships, such as position relationship, connection relationship, cooperation relationship, interaction relationship, etc., are described in detail. And explains the working principle and using method of the invention. Moving parts can be explained by their action process. This patent is obviously different from the patents in the prior art. 3. Advantages of this patent: It shows the beneficial effects or advantages of the mechanism of the invention, such as improving defects, increasing functions, reducing costs, simplifying the structure, being easy to manufacture, having low failure rate, being safe and reliable, being easy to operate, etc. 4. Attached drawings and explanation: Invention patents in the mechanical field attach great importance to attached drawings. Because it is too limited to describe the structure and position relationship of patents in the mechanical field in words, some technical contents cannot be clearly expressed without the help of attached drawings. The attached drawings of the mechanism or device of the present invention may have multiple drawings, and it is required that the structure of the present invention can be clearly expressed. The attached drawings can be engineering assembly drawings, three-dimensional schematic drawings, sectional views, partial enlarged views, partial sectional views, part drawings, etc. The drawings shall be marked with reference signs of their parts, structural features and other elements, so as to facilitate the reference of these signs in the text description.
