Vehicle Camera Bracket Assembly for 3D Field-of-View Recalibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera monitor systems in vehicles have fixed camera positions that may need recalibration due to changes in vehicle position or damage, limiting their effectiveness in providing optimal field of view.
Innovation Solution
A bracket assembly allowing adjustable movement of vehicle cameras in three dimensions (yaw, pitch, and roll) via interconnected brackets, enabling precise recalibration and compensation for vehicle position changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera position is fixed to simplify installation and reduce complexity, then the device complexity is reduced, but the field of view cannot be adjusted when vehicle position changes or damage occurs
Solution Approach 1:
The bracket assembly is divided into multiple independent brackets (first bracket for yaw adjustment, second bracket for pitch adjustment, third bracket for roll adjustment), each responsible for a specific adjustment function. This segmentation allows the system to achieve complex 3D camera positioning through simple, modular components that can be adjusted independently.
Solution Approach 2:
The brackets are configured in a nested arrangement where the first bracket is connected to the housing, the second bracket is connected to the first bracket, and the third bracket is connected to the second bracket. This nested structure enables compact integration of multiple adjustment mechanisms while maintaining accessibility for calibration purposes.
2Reliability
If the camera wing is replaced to restore proper field of view after damage, then the field of view is restored, but the cost and complexity of repair increases significantly
Solution Approach 1:
The bracket assembly transforms the static camera mounting into a dynamic system that can be adjusted and recalibrated after damage or vehicle repositioning. Instead of requiring replacement of the entire camera wing, the adjustable brackets allow field personnel to restore proper field of view by simply repositioning the camera through the bracket mechanisms.
Solution Approach 2:
The system allows change in camera position parameters (yaw, pitch, roll) through the bracket adjustments. This enables restoration of the correct field of view by modifying the positional parameters of the camera without replacing hardware components, significantly simplifying the repair process.
3Adaptability or versatility
If the camera is mounted in a fixed position to reduce adjustment mechanisms, then the device complexity is reduced, but the ability to compensate for vehicle position changes is lost
Solution Approach 1:
The patent replaces complex electronic or automated positioning systems with a simple mechanical adjustment mechanism using three brackets with fasteners. This mechanical approach allows direct manual adjustment of camera position to compensate for vehicle position changes, making the system easier to operate and calibrate in field conditions.

AI summary
A camera monitor system (CMS) for a vehicle includes a wing including a housing configured to be secured to the vehicle, and a camera assembly having a camera mounted to the wing with a bracket assembly. The camera may include an image capture unit configured to provide a desired field of view of the vehicle. A display may depict at least a portion of the field of view. A controller may be in communication with the camera and the display. The bracket assembly may include first, second, and third brackets configured for adjustment of the camera with respect to first, second, and third dimensions.
