Mechanical design usually needs to consider the following factors

Usage requirements: Mechanical design must be based on meeting the user's usage requirements. Understanding user needs, including functional requirements, performance requirements, cost requirements, and reliability requirements, is the key to mechanical design.
Working principle: According to the usage requirements, it is necessary to analyze the working principle of the machinery, clarify its workflow and the coordination relationship between various components. On this basis, design to ensure that the machinery can achieve the required functions.
Structure: Structure is an important part of mechanical design, involving the overall layout of the machine, the shape, size, materials, and other components. A reasonable structure can ensure the stability, strength, and stiffness of the machinery, while also considering the feasibility of manufacturing.
Motion mode: Mechanical design needs to determine the motion mode of the machine according to the usage requirements, including rotational motion, reciprocating motion, swinging, etc. Reasonable movement methods can ensure the efficiency and stability of the machinery.
The transmission methods of force and energy: Mechanical design needs to consider the transmission methods of force and energy, including transmission systems, control systems, lubrication systems, etc. A reasonable transmission method can ensure the efficiency and stability of the machinery.
Material and shape dimensions of parts: Mechanical design requires selecting appropriate materials and shape dimensions based on usage and structural requirements to ensure the mechanical performance requirements such as strength, stiffness, and wear resistance.
Lubrication method: Mechanical design needs to consider lubrication methods, select appropriate lubricants and lubrication systems, and ensure the lubrication effect and lifespan of the machine.
