Agricultural Cab Roof Camera Display System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Panoramic roofs on agricultural working machines are prone to damage from high loads, complicate rollover safety designs, and offer inadequate light adjustment, leading to visibility issues and operational challenges.
Innovation Solution
A display device and primary camera system are integrated into the cab's roof, allowing the machine operator to view the external environment above the roof structure through continuous video feed, with optional secondary camera coverage for rear and side areas, and infrared capabilities for night vision, enhancing visibility without the need for a physical panoramic roof.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a panoramic roof is installed to improve visibility of the work area above the roof, then the operator can see above the roof surface, but the glass is prone to damage from high loads and the cabin structure is weakened
Solution Approach 1:
The patent uses cameras to capture images of the area above the roof and displays these images on screens, creating a visual copy of the panoramic view. This eliminates the need for a physical glass panoramic roof while maintaining the visibility function. The camera system captures light reflected from the external environment and converts it into electrical signals for display, replicating the optical function without the structural weakness of glass panels.
2Illumination intensity
If a panoramic roof is installed to improve visibility, then the operator can monitor the work area above, but the cabin design becomes more complex and rollover safety is compromised
Solution Approach 1:
The patent replaces the mechanical glass panoramic roof structure with an electronic imaging system consisting of cameras, processors, and display screens. This substitution eliminates the need for complex structural reinforcement while achieving the same visibility purpose. The electronic system is more adaptable and easier to integrate into the existing cabin design without compromising structural integrity.
3Illumination intensity
If a panoramic roof is used to provide continuous viewing of the external environment, then the operator has constant visibility, but solar radiation constantly enters the machine causing glare and overheating
Solution Approach 1:
The camera system captures optical information and converts it into electrical signals for display, creating a copy of the external view without allowing actual sunlight to enter the cabin. This eliminates solar radiation, glare, and overheating issues while maintaining continuous visibility of the work area above the roof.
