Rearview Mirror Camera Mounting for Stable Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rearview mirror systems with integrated cameras face challenges in maintaining the camera's position stability during articulation of the mirror assembly, which affects image capture quality and reliability.
Innovation Solution
A mirror assembly design where a camera unit is connected to a mounting member within a housing that articulates relative to the mounting member along multiple axes, with a printed circuit board (PCB) statically coupled to the housing and mounting member, ensuring the camera remains stationary during articulation, and a flexible sleeve reduces ambient light interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the housing is articulated relative to the mounting member to enable adjustment of mirror positions, then the adaptability of the mirror assembly is improved, but the camera unit position stability deteriorates
Solution Approach 1:
The system is divided into two distinct segments: the housing containing the camera unit that remains stationary relative to the mounting member, and the mirror assembly that articulates independently. This segmentation allows the housing to maintain a fixed position for stable camera operation while the mirror can be adjusted to different positions, resolving the contradiction between adaptability and stability.
2Device complexity
If the camera unit is integrated into the housing that articulates, then the device complexity is reduced, but the measurement precision of image capture deteriorates
Solution Approach 1:
The camera unit is extracted from the articulating mirror assembly and placed in the stationary housing, separating the image capture function from the position-adjustment function. This extraction ensures that the camera remains in a fixed, stable position for precise image capture while the mirror can still be adjusted independently, resolving the contradiction between device integration and measurement precision.

AI summary
A mirror assembly for a vehicle includes a glass element that is at least partially reflective and a housing that is coupled to the glass element. A mounting member includes an internal portion located within the housing that defines a mounting member connector. The housing includes a housing connector operably coupled to the mounting member connector and configured to articulate the housing relative to the mounting member between different positions. A camera unit is connected to the internal portion of the mounting member such that it remains stationary as the housing is articulated relative to the mounting member.
