Replaceable Rearview Mirror Bracket With Ball-Clamping Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automobile interior rearview mirror supports, particularly double-ball-head and three-ball-head types, are difficult to replace due to their design, which limits adjustment angles and impact resistance, and often result in unstable rearview mirror installations.
Innovation Solution
A replaceable support system comprising a ball-clamping mechanism with a support base, an OEM base, a ball head base, a support pipe, a spring, and a conversion head, connected via a fastening screw, allowing for adjustable angles and secure locking to prevent looseness, while maintaining a compact and aesthetically pleasing design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional OEM double-ball-head or three-ball-head support is used, then the rearview mirror can be installed on the windshield, but the support cannot be replaced and has limited adjustment angle range
Solution Approach 1:
The support system is divided into three replaceable segments: the support base fixed in the rearview mirror, the replaceable support (ball head base, support pipe, conversion head), and the OEM base fixed on the windshield. This segmentation allows the middle segment to be easily replaced while keeping the outer segments fixed, solving both the replaceability and adjustment angle problems.
Solution Approach 2:
The connector with standardized screw holes and the conversion head with universal ball head interface enable the replaceable support to work with different rearview mirror models and OEM bases. This universality allows users to replace supports across different mirror types while maintaining adjustability and impact resistance.
2Adaptability or versatility
If a fixed support structure is used, then the rearview mirror installation is stable, but the support cannot be adjusted to different angles
Solution Approach 1:
The support pipe incorporates a ball-clamping mechanism with a movable clamping block that can shift between clamped and released states. When clamped, the pipe is fixed at a specific angle providing stability; when released, the pipe can be adjusted to different angles providing adaptability. This dynamic mechanism resolves the contradiction between fixed stability and adjustable versatility.
3Ease of repair
If a replaceable support mechanism is introduced, then the support can be exchanged between different mirrors, but the impact resistance and safety coefficient may be compromised
Solution Approach 1:
The support pipe includes a spring component positioned between the ball head base and conversion head. This spring acts as a cushioning element that absorbs impact forces during collisions, protecting the rearview mirror from shock damage. The spring's presence ensures that even though the support is replaceable, the impact resistance and safety coefficient are maintained through pre-installed shock absorption capability.
4Ease of manufacture
If the connector and replaceable support are loosely connected, then assembly is easy, but the connection becomes unstable and loose
Solution Approach 1:
The connection between the connector and replaceable support uses a ball-clamping mechanism that replaces simple mechanical screw fastening with a spring-loaded clamping system. The clamping block, driven by a screw, presses the conversion head against the connector with spring force, providing stable connection. This mechanical substitution maintains ease of assembly through screw operation while achieving superior connection stability through elastic clamping force.
