Extended data
The utility model is different from the invention in that:
First, the utility model is limited to products with a certain shape, and cannot be a method or product without a fixed shape; Second, the utility model is not too creative, but it is very practical.
In view of the low requirement of utility model for creativity, people generally call it small invention and small creation. However, it should be understood that for highly creative inventions, as long as they are the protected objects of utility models, they can also apply for utility model patents.
The shape of a product refers to the definite spatial shape that the product has and can be observed. The technical scheme proposed for product shape can be the technical scheme proposed for product three-dimensional shape, such as the improvement of cam shape and cutter shape; It can also be a technical scheme of two-dimensional shape of products, such as the improvement of sectional shape of profiles.
The structure of a product refers to the arrangement, organization and interrelation of various components of the product. The product structure can be either a mechanical structure or a circuit structure. Mechanical structure refers to the relative position relationship, connection relationship and necessary mechanical cooperation relationship between components that make up a product, and circuit structure refers to the determined connection relationship between components that make up a product.
The composite layer can be considered as the structure of the product, such as carburized layer and oxide layer of the product.
