Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling agricultural machines are inadequate in handling abrupt or sliding movements relative to the towing vehicle, leading to misalignment and reduced safety and efficiency during operation.
Innovation Solution
The method employs an acceleration sensor to detect the direction and magnitude of movements, allowing a control and regulating device to initiate automatic adjustments, such as altering tool positions or wheel actions, to maintain alignment and stability, and includes event-based decision logic for reactive measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated control measures are initiated based on acceleration detection, then safety and handling are improved, but device complexity increases
Solution Approach 1:
The agricultural machine automatically detects its own movement state through the acceleration sensor and initiates control measures without external intervention. The control device monitors acceleration data, determines reversal or abnormal movement autonomously, and triggers appropriate responses such as raising the implement, creating a self-monitoring and self-correcting system that improves safety while maintaining manageable complexity
Solution Approach 2:
The acceleration sensor continuously provides feedback about the machine's movement state to the control device. This feedback loop enables real-time detection of reversal or abnormal movements, allowing the system to respond dynamically to changing conditions. The control device uses this feedback to determine when control measures are needed and to monitor their effectiveness, creating a closed-loop control system that enhances safety
2Manufacturing precision
If automated control measures are initiated based on deviation from target movement, then precision and alignment are improved, but device complexity increases
Solution Approach 1:
The system establishes a target movement based on towing vehicle motion parameters and continuously compares actual movement against this target. The control device calculates deviation and uses this feedback to determine when alignment correction is needed, triggering automated control measures to restore proper positioning. This closed-loop feedback mechanism maintains precision while managing system complexity through event-based activation
Solution Approach 2:
The system pre-calculates target movement parameters based on towing vehicle motion before deviation occurs. By establishing the expected movement trajectory in advance, the system can quickly determine when actual movement deviates from the plan and initiate corrective action. This preliminary preparation enables faster response to alignment issues without requiring complex real-time calculations
