[Technical solution: refers to the collection of technical measures taken by the applicant for the technical problems to be solved. Technical measures are usually embodied by technical characteristics. The technical scheme shall clearly and completely explain the shape and structural features of the utility model, explain how the technical scheme solves the technical problems, and explain the scientific principles on which the technical scheme is based when necessary. Mechanical products in the preparation of technical solutions, should describe the necessary parts and their overall structural relationship; For products involving circuits, the connection relationship of circuits shall be described; Mechanical and electrical products should also explain the combination relationship between circuit and mechanical part; When applying for distributed parameters, the mutual position relationship of components should be explained; When it comes to integrated circuits, the model and function of integrated circuits should be clearly disclosed. In this example, the structural features of the electric pen include the connection relationship between the mechanical structure and the circuit, so it is necessary to state the relationship between the main mechanical parts and their overall structure and the connection relationship of the circuit. The technical scheme can not only describe the principle, function, name, function or use of each component.
You have no examples, so you can write? Too strong! Go to China National Intellectual Property Administration to download an example. You'd better know more about it and don't apply in a hurry, lest all the things you apply for can't be sold, or other similar patents will appear soon! ! !
