Exterior Mirror Unit Detachable Support Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exterior mirror units for vehicles are costly to replace due to the difficulty and expense of removing and replacing the mirror support and actuator unit when the mirror support or mirror cap is damaged, as the actuator unit is typically not easily detachable from the mirror base.
Innovation Solution
The exterior mirror unit design allows for the mirror support to be detachably connected with the actuator unit and mirror base as a whole, enabling simple detachment and replacement of the mirror support without requiring the expensive actuator unit to be replaced, using a single fixing means such as a screw, snap connection, or other mechanisms for easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mirror support is permanently fixed to the actuator unit and mirror base, then the structural stability and reliability are improved, but the ease of repair deteriorates when the mirror support or mirror cap is damaged
Solution Approach 1:
The exterior mirror unit is divided into separable modules: the mirror support assembly (including mirror support and mirror cap) can be detached from the actuator unit, which remains fixed to the mirror base. This segmentation allows the mirror support to be replaced independently without replacing the expensive actuator unit, resolving the contradiction between structural stability and ease of repair.
2Ease of repair
If the mirror support is made detachable from the actuator unit, then the ease of repair is improved, but the device complexity increases
Solution Approach 1:
The actuator unit is received within a reception facility in the mirror support, creating a nested arrangement. The actuator unit can be inserted into and removed from the mirror support through the reception facility, providing a simple detachable connection mechanism that balances ease of repair with minimal device complexity.
3Manufacturing precision
If the actuator unit is integrated with the mirror support as a single assembly, then the manufacturing precision is improved, but the loss of substance increases when replacing damaged parts
Solution Approach 1:
The mirror support and mirror cap are extracted as a separate replaceable assembly from the actuator unit. When the mirror support or mirror cap is damaged, only this extracted assembly needs to be replaced, not the entire integrated unit, thereby reducing material waste and avoiding replacement of the expensive actuator unit.
