Adjustable Display Mounting for Work Machine Operator Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing working machine displays lack the necessary flexibility to accommodate various operator positions and viewing angles, limiting operator visibility and ergonomic comfort.
Innovation Solution
The implementation of a dual display mounting system that allows for adjustable positions and orientations of display devices relative to the operator seat and overhead control station, enabling on-the-fly adjustments to enhance visibility and ergonomics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed display mounting system is used, then the display position is stable and simple to manufacture, but the operator cannot adjust the display to accommodate different operator positions and viewing angles
Solution Approach 1:
The display mounting system transitions from a fixed structure to a dynamic, adjustable structure that allows the display to be repositioned in multiple directions (laterally, vertically, and angularly) to accommodate different operator positions and preferences, directly resolving the contradiction between adaptability and complexity
Solution Approach 2:
The mounting system is divided into multiple independent adjustment mechanisms (lateral adjustment, vertical adjustment, angular adjustment) that can be modified separately, allowing the system to achieve high adaptability while maintaining manageable complexity through modular design
2Adaptability or versatility
If the cab position and seat position are made adjustable, then operator visibility and flexibility are enhanced, but the display position becomes misaligned with the operator's viewing needs
Solution Approach 1:
The display mounting system is made dynamically adjustable to move and reposition the display in coordination with changes in cab and seat positions, ensuring the display remains aligned with the operator's viewing needs while maintaining the flexibility benefits of adjustable positions
Solution Approach 2:
The system incorporates feedback mechanisms that detect the operator's position and viewing angle, automatically or manually adjusting the display position to maintain optimal alignment, thereby preserving ease of operation while enhancing overall adaptability

AI summary
A work machine can include an operator station, an overhead control station, a first display mounting system, a second display mounting system, a first display device, and a second display device. The operator station can include a rotatable seat. The first display mounting system can be connected to the overhead control station. The first display device can be connected to the first display mounting system. The second display mounting system can be connected to the rotatable seat, and the second display device can be connected to the second display mounting system. The first display mounting system can be operable to selectably adjust a position of the first display device relative to the overhead control station, and the second display mounting system can be operable to selectably adjust a position of the second display device relative to the rotatable seat.
