Multi-Camera Cab Assembly for Heavy-Vehicle Blind Spot Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heavy-duty vehicle operators experience reduced visibility and blind spots due to their elevated position, which increases the risk of accidents.
Innovation Solution
A camera assembly with multiple cameras mounted in a housing that captures images from different angles and angles, including rearward and frontward fields of view, to provide comprehensive visibility, potentially replacing traditional rearview mirrors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cameras are mounted to capture different areas around the vehicle, then operator visibility and safety are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple cameras (first camera for rearward view, second camera for angled rearward view, third camera for frontward view) into a single integrated camera assembly mounted on the vehicle cab. This merging approach provides comprehensive visibility coverage while consolidating the system into one unified device rather than separate mirror and camera systems.
Solution Approach 2:
The patent transitions from traditional 2D rearview mirrors to a multi-dimensional camera system that captures images from multiple angles and dimensions simultaneously. The cameras are positioned to capture rearward views, angled rearward views, and frontward views, creating a three-dimensional awareness of the vehicle surroundings that eliminates blind spots.
2Loss of information
If cameras are positioned distally and laterally offset from the attachment, then blind spots such as A-pillar areas are captured, but manufacturing precision requirements increase
Solution Approach 1:
The patent positions each camera with specific local quality characteristics - the first camera is positioned for general rearward coverage, the second camera is positioned at an angle to capture the A-pillar blind spot area, and the third camera is positioned for frontward view. Each camera's position is optimized for its specific function, allowing the system to capture all necessary areas while maintaining feasible manufacturing tolerances.

AI summary
The inventive concept relates to a camera assembly for a vehicle, the camera assembly comprising a camera housing configured to mount to a vehicle cab of the vehicle, a first camera lens of a first camera mounted to a rear side of the camera housing to capture a first image, a second camera lens of a second camera mounted to the rear side of the camera housing to capture a second image, a third camera lens of a third camera mounted to a front side of the camera housing to capture a third image, and a fourth camera lens of a fourth camera mounted to the front side of the camera housing to capture a fourth image.
