Adaptive Agricultural Display Control for Visibility and Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural machinery displays are inflexible, often obstructing the operator's view or risking collision, and lack adaptive mechanisms to optimize display size and visibility based on operational needs.
Innovation Solution
A control unit and sensor system adjust retractable and extendable displays using actuators, detecting obstacles and seat rotation to prevent collisions and optimize display size, allowing flexible adaptation based on operational requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed display is used in the agricultural machine, then the display structure is simple and stable, but the display obstructs the operator's view and risks collision with obstacles
Solution Approach 1:
The display is transformed from a fixed structure to a dynamic moveable display that can change its position and size automatically. The control unit receives sensor data about obstacles and seat rotation, then controls the actuator to move the display accordingly, allowing it to adapt dynamically to different operational conditions while maintaining simplicity of structure.
Solution Approach 2:
The moveable display system operates autonomously by receiving sensor data from the sensor system, analyzing it through the control unit, and automatically adjusting its position and size without requiring manual intervention from the operator. This self-service mechanism resolves the contradiction by making the display responsive to environmental conditions while keeping the control system relatively simple.
2Ease of operation
If a moveable display is used to prevent collision and optimize visibility, then operator visibility is improved, but the device complexity increases due to actuators and sensor systems
Solution Approach 1:
The moveable display serves multiple functions: it displays information, prevents collision with obstacles by moving away, optimizes visibility by adjusting position based on seat rotation, and can change size to accommodate different operational needs. This multi-functionality justifies the increased device complexity by consolidating several functions into a single adaptive system.
Solution Approach 2:
The system implements a feedback loop where the sensor system continuously monitors the environment (obstacles, seat position), the control unit analyzes this data, and the actuator adjusts the display position and size accordingly. This feedback mechanism enables the display to adapt automatically to changing conditions, resolving the contradiction between adaptability and control system complexity.
3Loss of information
If the display is extended to show more information, then information presentation is optimized, but the display may collide with obstacles or block the operator's view
Solution Approach 1:
The display size and position are dynamically adjusted based on real-time sensor data. When obstacles are detected or when the display might block the operator's view, the control unit commands the actuator to retract or reposition the display. This dynamic adjustment allows the system to maximize information visibility while minimizing collision risk and view obstruction.
Solution Approach 2:
The sensor system detects obstacles and seat rotation in advance, allowing the control unit to preemptively adjust the display position and size before a collision or view obstruction occurs. This preliminary anti-action prevents harmful effects by proactively responding to potential issues rather than reacting after they occur.
