Auxiliary Rearview Mirror Mounting Structure with Adjustable Hooks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional auxiliary rearview mirror mounting structures face issues with mounting instability due to elastic fatigue in flexible straps and non-adjustability to different main rearview mirror curvatures, leading to image blur and risk of the auxiliary mirror falling.
Innovation Solution
The proposed auxiliary rearview mirror mounting structure features support arms with pivot joints and adjustable hooks, equipped with tightening devices that include friction pads and ball sockets for secure attachment to various main rearview mirrors, along with a flexible cap member to match different rim curvatures, enhancing stability and ease of mounting/dismounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If flexible straps are used to secure the auxiliary mirror, then the mounting structure can be simple and easy to install, but elastic fatigue occurs after long use leading to mounting instability
Solution Approach 1:
The invention replaces durable but complex rigid mounting structures with a simpler, potentially replaceable strap system. The strap is designed as a separate, easily replaceable component that can be discarded and renewed when it shows signs of fatigue, rather than replacing the entire mounting structure.
Solution Approach 2:
The mounting structure transitions from a static rigid connection to a dynamic system where the strap can flex and adjust. The strap's flexibility allows it to adapt to vibrations and movements during vehicle operation, maintaining contact and stability despite the dynamic environment.
2Device complexity
If a fixed rod member is used to hook onto the main rearview mirror rim, then the structure is simple, but it cannot adjust to different rim curvatures of various main rearview mirrors
Solution Approach 1:
The rod member incorporates pivot joints that enable it to change its configuration dynamically. This allows the rod to adapt its shape and angle to match different rim curvatures of various main rearview mirrors, providing versatility without requiring multiple fixed-configuration rods for different mirror types.
Solution Approach 2:
The rod member is divided into multiple segments connected by pivot joints. This segmentation allows each segment to rotate independently, enabling the rod to conform to different curvature profiles while maintaining structural integrity and simplicity in its modular design.
3Reliability
If tightening devices with friction pads are added to secure hooks, then mounting stability is improved, but the device complexity increases
Solution Approach 1:
The invention replaces complex mechanical fastening systems (such as multiple bolts, clamps, or locking mechanisms) with a simpler friction-based tightening device. The friction pad creates sufficient holding force through friction alone, eliminating the need for elaborate mechanical interlocking systems while maintaining mounting stability.

AI summary
An auxiliary rearview mirror mounting structure includes two support arms of angularly adjustable multi-segment design pivotally connected to an auxiliary rearview mirror, multiple hooks located at each support arm for hooking on the rim of a main rearview mirror, and tightening-up devices mounted in each support arm corresponding to one respective hook and rotatably movable inwards and backwards for abutting against the rim of the main rearview mirror to lock the hooks to the rim of a main rearview mirror.
