Rear-View Mirror Mounting Structure With Interchangeable Arm Kits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no universal connecting structure between existing external rear-view mirrors and fixing members, requiring users to replace the mirrors and redesign fixing holes for each vehicle type, leading to additional costs and inefficiencies.
Innovation Solution
A universal external rear-view mirror mounting structure featuring a hemispherical joint and connecting arm kit that allows the mirror to be assembled with a mounting groove, eliminating the need for mirror replacement and enabling adaptable fixing to various vehicles using interchangeable connecting arm kits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal connecting structure is not adopted, then each external rear-view mirror requires redesign of fixing holes for each vehicle type, but this leads to increased manufacturing costs and product complexity
Solution Approach 1:
The patent applies universality by designing a standardized hemispherical mounting groove and corresponding connecting member that can be used across different vehicle types. The connecting member with universal interface allows the same external rear-view mirror housing to be adapted to various vehicles by simply changing the connecting arm kit, eliminating the need to redesign fixing holes for each vehicle model.
2Reliability
If existing external rear-view mirrors are replaced for each vehicle type, then proper fixation is achieved, but this increases user costs and loss of time
Solution Approach 1:
The patent segments the external rear-view mirror system into modular components: a universal housing with standardized hemispherical mounting groove, and vehicle-specific connecting arm kits. This segmentation allows users to keep their existing mirror housings and only replace the connecting arm kit when changing vehicles, reducing time and cost while maintaining fixation reliability through the standardized interface.
3Manufacturing precision
If vehicle-specific fixing members are designed for each mirror type, then precise fitting is achieved, but this increases manufacturing precision requirements and productivity costs
Solution Approach 1:
The standardized hemispherical interface serves as a universal connection standard that reduces manufacturing precision requirements. Instead of designing unique fixing holes for each vehicle-mirror combination, manufacturers can produce mirror housings with a single standardized hemispherical groove design, significantly improving productivity while maintaining adequate fit through the geometric constraints of the hemispherical shape.

AI summary
Disclosed in the present disclosure is an external rear-view mirror mounting structure, including an external rear-view mirror, in which the external rear-view mirror includes: a housing; a mirror, removably mounted on a front side of the housing; and a connecting member, in which a rear side of the housing is provided with a mounting groove with hemispherical shape, an end of the connecting member is provided with a hemispherical joint fitted with the mounting groove, and an opposite end of the connecting member is provided with a connecting arm kit configured to fix with a target vehicle. The beneficial effect of the utility model is that the user only needs to replace the connecting arm kit including the hemispherical joint by providing a mounting groove at a back side of the external rear-view mirror, without the necessity of replacing the external rear-view mirror, which saves the user's usage costs.
