Three-Point Attachment System for Vehicle Mirror Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachment mirrors for vehicles have limited viewing angles, are complex and expensive to construct, and can cause vibrations during use, making them unsuitable for driving lessons and tests, especially due to the 'blind spot' issue and the need for multiple versions for left and right installations.
Innovation Solution
A three-point attachment system with adjustable clamping brackets and an adjustment foot allows for stable, vibration-free mounting of an attachment mirror on exterior mirrors, enabling easy assembly and adjustment, reducing the blind spot, and allowing use on both left and right sides without obstructing the candidate's view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fastening means are used to attach the attachment mirror, then the mirror can be mounted on the exterior mirror, but vibrations occur during driving and the attachment is unstable
Solution Approach 1:
The attachment system is divided into three separate attachment points distributed across the housing surface, rather than using a single centralized fastening mechanism. This segmentation distributes mechanical stresses and vibrations across multiple locations, preventing resonant vibrations and improving overall attachment stability during vehicle operation.
Solution Approach 2:
The attachment means extends in multiple spatial dimensions by using three attachment points positioned at different locations on the housing surface. This three-dimensional distribution of attachment points creates a more rigid and stable mounting structure that resists vibrations from multiple directions simultaneously.
2Reliability
If complex fastening systems are used to achieve stable attachment, then vibration-free mounting is possible, but the device becomes complex and expensive to construct
Solution Approach 1:
The three attachment points serve multiple functions simultaneously: they provide stable mechanical support, distribute vibrational forces, enable precise positioning of the mirror, and allow for potential adjustment. This multi-functionality eliminates the need for separate complex mechanisms for each function, simplifying the overall construction while maintaining high reliability.
3Area of stationary object
If the attachment mirror is added to increase viewing angle, then the blind spot is reduced, but the candidate driver's view may be obstructed
Solution Approach 1:
The attachment mirror is positioned and sized to provide specific local viewing coverage of the blind spot area, rather than attempting to provide a complete 360-degree view. The mirror's location and angular orientation are optimized to cover only the necessary blind spot region, ensuring that the candidate driver's primary forward view remains unobstructed while still gaining blind spot awareness.

AI summary
The mirror (10) has a housing (11) provided with a mirror surface, a fixing unit arranged for the attachment of the housing of the attachment mirror with the housing of the outer mirror. The fixing unit comprises three gripping units, in which two gripping units are designed as a clamping bracket, which is gripped around the edges of the housing of the outer mirror, and the third gripping unit is designed as a gauge foot. The gauge foot is supported at the housing of the outer mirror.
