Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional spherical shell structure is used for up and down adjustment, then the mirror surface can be adjusted to different angles, but shaking and distortion occur during the adjustment process
Solution Approach 1:
A positioning structure with positioning guide raised lines and positioning guide grooves is introduced as an intermediary between the actuator and the mirror assembly. This positioning structure guides the relative rotation between spherical shells, ensuring the mirror surface adjusts along a predetermined trajectory without shaking or distortion, thus solving the contradiction between adjustability and stability.
2Adaptability or versatility
If front and rear folding adjustment is implemented, then the mirror surface can be adjusted, but the adjustment process is complex
Solution Approach 1:
The invention uses a spherical shell structure where the actuator spherical shell and housing spherical shell rotate relative to each other. This spherical geometry simplifies the adjustment mechanism by allowing rotation around a fixed point, reducing the complexity compared to traditional folding mechanisms while maintaining multi-directional adjustment capability.
3Stability of the object's composition
If positioning guide raised lines and grooves are added to guide rotation, then shaking is reduced, but the device complexity increases
Solution Approach 1:
The positioning structure utilizes the existing spherical shell geometry, with raised lines and grooves formed as curved features on the spherical surfaces. This integration of positioning features into the spherical design minimizes additional complexity while effectively guiding the rotation and reducing shaking during adjustment.

AI summary
The present disclosure relates to an actuator spherical shell structure, comprising an actuator spherical shell surface (142) located inside a housing and a housing spherical shell surface (420) located outside the actuator (200) and rotating in coordination with the actuator spherical shell surface. The actuator is connected to the housing for driving, and a positioning structure is provided between the actuator and the housing. Under the guidance of the actuator's driving and positioning structure, the housing flips the rear-view element (300) installed along the set direction via the housing spherical shell surface around the actuator spherical shell surface. A rear-view mirror and a vehicle comprising the above actuator spherical shell structure are also disclosed. The present disclosure has the beneficial effects below: the positioning structure can guide the relative rotation between the actuator spherical shell surface and the housing spherical shell surface; compared with traditional spherical shell structures, it can effectively avoid shaking of the rear-view element during angle adjustment, improving user comfort.
