Agricultural Machine Control Override for Manual Parameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural work machines operating in automatic mode cannot allow for short-term manual adjustments of working parameters, requiring a complete interruption of the work process to switch between automatic and manual operation.
Innovation Solution
An agricultural work machine equipped with a control device that allows for continuous operation in automatic mode, enabling operators to manually override specific working parameters by actuating control elements, such as a steering wheel, without interrupting the overall processing strategy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the agricultural machine operates in automatic mode with a pre-planned processing strategy, then the productivity and autonomy of the machine are improved, but the adaptability to temporarily changing conditions and the ease of manual adjustment of working parameters deteriorate
Solution Approach 1:
The control device is designed to dynamically switch between automatic and manual control of specific working parameters while maintaining automatic operation of other parameters. This allows the system to adapt its control mode in real-time based on operational needs, resolving the contradiction between autonomous operation and manual adjustability.
Solution Approach 2:
The control system is segmented into independently controllable parts: the processing strategy (route, speed, timing) remains under automatic control, while specific working parameters (depth, width, intensity) can be independently switched to manual control. This segmentation allows simultaneous automatic and manual operation at different levels of the control hierarchy.
2Reliability
If the machine requires complete interruption of the work process to switch between automatic and manual mode, then the control reliability is improved, but the productivity and continuity of operation deteriorate
Solution Approach 1:
The system dynamically adjusts the level of automation for different parameters without requiring mode switching interruptions. The control device continuously monitors and manages multiple parameters with different control modes simultaneously, maintaining both reliability and operational continuity.
Solution Approach 2:
The machine maintains continuous operation by allowing manual adjustment of specific working parameters without interrupting the overall automatic processing strategy. The work process flows continuously while individual parameters can be temporarily adjusted manually and then automatically resume.
3Adaptability or versatility
If the operator can manually override working parameters during automatic operation, then the adaptability to changing conditions is improved, but the complexity of the control system increases
Solution Approach 1:
The control device is segmented to handle automatic and manual control separately for different parameters. Each parameter can be independently configured for automatic or manual control, simplifying the overall control architecture while enabling flexible adaptability.
4Ease of operation
If complete mode switching is required to adjust working parameters, then the ease of operation is improved by maintaining clear operational states, but the productivity and responsiveness to changing conditions deteriorate
Solution Approach 1:
The control system provides clear operational feedback about which parameters are under manual vs. automatic control, maintaining state clarity while enabling dynamic adjustments without full mode switching. The operator can see which parameters are adjustable and which are following the automatic strategy.
