Operator Seat Position Sensor Adjusts Display Perspective
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display systems for machines like backhoe loaders do not provide appropriate image adjustments based on the operator seat's orientation, leading to incorrect perspectives and hindering efficient operation.
Innovation Solution
A display system with multiple imaging devices and a position sensor that captures and adjusts the image displayed on the screen based on the operator seat's position, ensuring a correct perspective of the environment around the machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a display screen is provided with the operator seat to show environment around the machine, then the operator can view the surroundings efficiently, but the display screen does not provide appropriate adjustment to the image with the change in orientation of the operator seat, leading to incorrect perspective
Solution Approach 1:
The display system dynamically adjusts the displayed image based on the operator seat's orientation position. The control unit receives signals from the position sensor detecting seat orientation and automatically modifies the image content and perspective on the display screen to match the operator's current viewing direction, making the system adaptive rather than static
Solution Approach 2:
The system implements a feedback loop where the position sensor continuously detects the operator seat's orientation position and sends signals to the control unit. The control unit processes this feedback information and adjusts the displayed image accordingly, ensuring the perspective remains correct regardless of seat position changes
2Adaptability or versatility
If the operator seat orientation changes between anterior and posterior positions for loader and backhoe operations, then the operator can perform various operations, but the display screen shows incorrect perspective images that make it difficult to operate the machine as required
Solution Approach 1:
The display system adapts dynamically to different seat orientations by receiving position signals from the sensor and automatically adjusting the displayed image perspective. When the seat rotates between anterior and posterior positions, the control unit modifies the image content to show the appropriate environmental view for each orientation, maintaining ease of operation across all positions
Solution Approach 2:
The display screen serves multiple functions by showing different perspectives based on seat orientation. It can display anterior views when the seat faces forward for loader operations and posterior views when the seat faces backward for backhoe operations, making the single display system universally useful for all operating positions
