Solution Overview
Problem
Existing mirror mounts for vehicles lack a simple, cost-effective solution that balances folding forces and stability while allowing for adjustable and secure attachment to a vehicle.
Innovation Solution
A mirror mount design featuring a pivot joint with a bayonet lock mechanism, utilizing a hollow bolt and spring system for adjustable torque and angular positioning, which replaces traditional screw connections and provides a detachable and stable attachment to the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw connection is used to connect the mirror arm to the mirror base, then the connection is secure and stable, but the attachment process is time-consuming and complex
Solution Approach 1:
The connection system is segmented into a hollow bolt with locking lugs, a bearing block with connecting links, and a spring mechanism. This segmentation allows for quick bayonet-style attachment while maintaining secure connection through distributed locking points, resolving the contradiction between quick attachment and secure connection.
Solution Approach 2:
The spring mechanism provides dynamic adjustment of the connection force, allowing the mirror arm to be quickly attached while maintaining stable connection under varying loads. The spring compensates for manufacturing tolerances and maintains consistent contact pressure without requiring complex adjustment procedures.
2Reliability
If a Quicklock safety washer is used with a bolt, then the connection is secure, but the parts are permanently connected and lack adjustability
Solution Approach 1:
The connection system is designed to be dynamically adjustable through the spring mechanism and multiple angular positions of the locking lugs. The spring allows for force adjustment, and the hollow bolt can be rotated to different angular positions, providing both security and adaptability unlike permanent Quicklock connections.
Solution Approach 2:
The connection parameters such as spring force and angular position can be changed to adapt to different requirements. The spring constant can be selected based on required folding forces, and the hollow bolt can be positioned at different angles, enabling the same connection system to adapt to various operational conditions.
3Ease of manufacture
If adhesive connections or clip connections are used, then the attachment is simple and quick, but the connection is not detachable
Solution Approach 1:
The connection is segmented into discrete mechanical components (hollow bolt, locking lugs, connecting links, spring) that can be easily assembled and disassembled. This mechanical segmentation provides both simplicity of attachment and ease of detachment, unlike adhesive connections which are permanent or clip connections which may lack structural integrity.
Solution Approach 2:
The spring acts as an intermediary element that maintains continuous contact force between the hollow bolt and bearing block during attachment and detachment operations. This intermediary spring mechanism simplifies the attachment process while enabling controlled detachment, bridging the gap between simple mechanical connections and secure detachable connections.
4Force
If the spring force is made adjustable by positioning a nut on the screw, then the folding forces can be optimized, but the device complexity increases
Solution Approach 1:
The spring constant is selected to provide the required folding force, and this parameter can be changed by selecting different spring specifications rather than adding complex adjustment mechanisms. The hollow bolt design with integrated spring and locking lugs maintains simplicity while allowing force optimization through parameter selection.
Solution Approach 2:
The spring mechanism automatically adjusts to maintain optimal contact force between connection components without requiring external adjustment mechanisms. The elastic properties of the spring provide self-regulating force, eliminating the need for nuts, screws, or other complex adjustment devices while still optimizing the folding force.

AI summary
The invention relates to a mirror holder for securing a mirror (100) to a vehicle, said mirror holder comprising a mirror base (200) that can be secured to the vehicle and a mirror arm (300) which is joined to the base of the mirror (200) by a rotary joint (400). Said rotary joint (400) comprises a support (210) which is arranged in the base of the mirror (200), a counter support which is arranged in the mirror arm (300) and an axis component (500). Said axis component (500) is secured to the base of the mirror (200) and to the mirror arm (300). Said mirror holder is characterised by virtue of the fact that the axis component (500) is secured to the mirror arm (300) or to the base of the mirror (200) in the form of a bayonet coupling.
