Vehicle Rearview Mirror Camera Mounting Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for integrating front cameras in vehicles, such as those mounted on windshields, suffer from noise pollution, vibrations, and visibility issues due to the need for bulky covers and complex mechanical elements.
Innovation Solution
A rear-view mirror assembly with a foot that incorporates a housing and contact zones to securely mount a camera without a glued base on the windshield, using symmetrical clips and a clamp nut for stabilization, allowing the camera to be integrated directly onto the mirror's foot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a camera is mounted on the windshield via a bonded base, then the camera can be fixed in position, but this generates noise pollution and vibrations
Solution Approach 1:
The patent extracts the camera mounting function from the windshield bonding system and relocates it to the rearview mirror assembly. The camera is now integrated into the mirror housing with dedicated mounting features ( ribs and contact zones) that provide stable fixation without requiring adhesive bonding to the windshield, thereby eliminating the source of vibration and noise associated with bonded bases.
Solution Approach 2:
The patent merges the camera mounting function with the rearview mirror assembly by integrating the camera housing and mounting structure into the mirror's foot. This combination allows the camera to be supported by the mirror assembly's structural elements (ribs, contact zones) rather than requiring a separate bonded base on the windshield, thus eliminating harmful vibrations while maintaining reliable fixation.
2Reliability
If a bonded base is used to fix the camera on the windshield, then the camera can be securely mounted, but this conceals part of the windshield and affects visibility
Solution Approach 1:
The patent extracts the camera mounting location from the windshield surface and relocates it to the rearview mirror assembly. This extraction eliminates the need for a bonded base on the windshield, thereby preserving the full visible area of the windshield while maintaining secure camera mounting through the mirror assembly's integrated housing and contact zones.
3Reliability
If a bonded base is used to mount the camera, then the camera can be fixed, but this creates a complex mechanical structure with many elements
Solution Approach 1:
The patent merges the camera mounting structure with the rearview mirror assembly by integrating the housing, ribs, and contact zones into the mirror's foot. This integration eliminates the need for separate bonded bases and reduces the number of mechanical elements required, thereby simplifying the overall structure while maintaining reliable camera fixation.
Solution Approach 2:
The rearview mirror assembly serves multiple functions: it provides the rearview mirror function and simultaneously serves as the camera mounting structure. The housing, ribs, and contact zones of the mirror assembly are designed to also function as camera support and fixation elements, thereby eliminating the need for dedicated camera mounting components and reducing overall device complexity.
