Vehicle Mirror Camera Fixed Position Telescopic Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle mirror assemblies with telescopic movement do not maintain the camera in a fixed position relative to the vehicle, which is crucial for accurate image processing in video systems, especially when the mirror housing is moved between retracted and extended positions.
Innovation Solution
A vehicle mirror assembly design where the camera is coupled to the vehicle attachment member via a tether, allowing it to remain fixed in position within a recess of the mirror housing during telescopic movement, ensuring consistent image capture across both positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the mirror housing is made telescopic to provide increased field of view, then the field of view is improved, but the camera position becomes unstable relative to the vehicle
Solution Approach 1:
The mirror assembly is divided into separate functional components: the mirror housing that undergoes telescopic movement for field of view adjustment, and the camera mounting structure that remains fixed to the vehicle attachment member. This segmentation allows independent optimization of each component - the mirror housing can move to provide varied viewing angles while the camera maintains a stable, fixed position for consistent image capture.
2Adaptability or versatility
If the mirror housing moves between retracted and extended positions to accommodate parking and driving conditions, then the adaptability is improved, but the camera image consistency deteriorates
Solution Approach 1:
The camera is extracted from the mirror housing structure and mounted independently on the vehicle attachment member. This extraction separates the camera's function from the mirror housing's telescopic movement, allowing the mirror to adapt between retracted and extended positions while the camera remains stationary relative to the vehicle, ensuring consistent image capture across all mirror positions.
3Device complexity
If the camera is integrated into the mirror housing for compact design, then the device complexity is reduced, but the camera's fixed position relative to the vehicle is compromised
Solution Approach 1:
The vehicle attachment member serves as an intermediary structure between the mirror housing and the camera. The camera is mounted on this intermediate structure rather than directly in the mirror housing, allowing the system to maintain relatively simple overall architecture while ensuring the camera's position is determined by the stable attachment member rather than the moving mirror housing.

AI summary
A vehicle mirror assembly includes a vehicle attachment member, a mirror housing, a mirror and a camera. The vehicle attachment member is configured for attachment to a vehicle. The mirror housing is telescopically coupled to the vehicle attachment member between a retracted position and an extended position relative to the vehicle attachment member. The mirror housing defines a camera receiving recess. The mirror is coupled to the mirror housing. The camera is coupled to the vehicle attachment member and disposed in the camera receiving recess of the mirror housing at a fixed position relative to the vehicle attachment member while the mirror housing is moved between the extended position and the retracted position.
