Rotating Side-View Mirror Camera for Semi-Truck Backing Turns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers of semi-trucks face visibility issues during backing turns due to the trailer pivoting relative to the truck, causing the side-view mirror to point away from the trailer's tail end, leading to loss of visibility.
Innovation Solution
A semi-truck side-view mirror with an integral camera and rotation mechanism that keeps the trailer's tail end in view by rotating the mirror about a vertically-oriented axis, combined with a display screen showing the camera's image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the side-view mirror remains fixed during backing turns, then the mirror structure is simple and stable, but the driver loses visibility of the trailer's tail end as the trailer pivots
Solution Approach 1:
The side-view mirror is transformed from a fixed structure to a dynamically adjustable one. The rotation mechanism enables the mirror to rotate about a vertically-oriented axis, allowing it to adapt its orientation during backing turns to maintain visibility of the trailer tail end.
Solution Approach 2:
The system incorporates a camera that captures images of the trailer tail end and displays them on a screen mounted on the mirror housing. This feedback loop provides the driver with continuous visual information about the trailer position, compensating for the mirror's rotation and ensuring reliable visibility.
2Reliability
If the side-view mirror rotates during backing turns to maintain visibility, then the driver maintains visibility of the trailer tail end, but the mirror structure becomes more complex with additional rotation mechanism
Solution Approach 1:
The side-view mirror assembly is designed to perform multiple functions: it serves as both a traditional reflective mirror for general side viewing and as a rotatable camera-mounted unit for enhanced backing visibility. This multi-functionality justifies the added complexity by providing superior operational capability.
Solution Approach 2:
The camera acts as an intermediary device that captures visual information from areas not directly visible in the mirror reflection. The camera is positioned to view the trailer tail end, and its images are displayed on the screen, mediating the driver's perception of the blind zone.
3Reliability
If a camera is integrated into the side-view mirror to capture trailer images, then the driver gains enhanced visibility through the display screen, but the device complexity increases with additional camera and display components
Solution Approach 1:
The camera, display screen, and mirror housing are merged into a single integrated assembly. The camera is mounted within the mirror housing, and the display screen is mounted on the housing, creating a unified device that combines traditional mirroring with electronic imaging capabilities.
Solution Approach 2:
The system adds a new dimension of visibility by incorporating electronic display technology. Instead of relying solely on optical reflection in the mirror plane, the camera-capture-and-display approach creates a virtual image dimension that supplements the physical mirror reflection.

AI summary
The semi-truck side-view mirror with integral camera comprises a side view mirror, a camera, a rotation mechanism, a mounting arm, and a display screen. The semi-truck side-view mirror with integral camera may be adapted to provide a driver with visibility of a tail end of a trailer during a backing turn. The camera within the side view mirror may present an image on the display screen showing the tail end of the trailer. During the backing turn, the rotation mechanism may rotate the side view mirror about a vertically-oriented axis of rotation to keep the tail end of the trailer within the field of view of the camera.
