Tractor-Mounted Implement Lift Control for Ground-Clearance Maneuvers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural attachment machines face delays in field work due to long idle times when soil cultivating and material depositing devices are lifted to a fixedly high position to avoid ground collisions during maneuvering, leading to unnecessary downtime and energy consumption.
Innovation Solution
Implementing a method with at least two predefined lifting positions for soil cultivating and material depositing devices, categorized by maneuvering operations, allowing for optimal lifting based on the specific maneuver, minimizing the risk of ground contact and reducing idle times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If soil cultivating and material depositing devices are lifted to a fixedly high position to avoid ground collisions during maneuvering, then the risk of damage from ground contact is reduced, but idle time and field work delays increase
Solution Approach 1:
The system dynamically adjusts the lifting position of soil cultivating and material depositing devices based on the detected maneuvering operation category. Instead of using a fixed high lifting position for all maneuvers, the control device selects from multiple predefined lifting positions (first through fourth positions) according to the specific maneuvering context, optimizing both protection and time efficiency
Solution Approach 2:
The invention changes the parameter of lifting position height based on maneuvering conditions. By categorizing maneuvers into different types (e.g., tight turns, wide turns, headland operations) and assigning appropriate lifting positions from multiple predefined options, the system adapts the lifting height parameter to match the actual risk level of ground contact for each maneuver type
2Reliability
If soil cultivating and material depositing devices are lifted to a fixedly high position to prevent ground contact, then device protection is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts the lifting position based on maneuvering detection, selecting the minimum necessary elevation from multiple predefined positions. This dynamic adaptation ensures devices are lifted sufficiently to avoid ground contact during detected maneuvers while avoiding unnecessary elevation that would waste energy
Solution Approach 2:
The lifting height parameter is changed according to maneuvering category. The control device selects from multiple predefined lifting positions (first through fourth positions) based on the detected maneuver type, optimizing the energy-lifting work required while maintaining adequate protection against ground contact
3Productivity
If multiple predefined lifting positions are implemented with categorization of maneuvering operations, then field work efficiency is improved, but control system complexity increases
Solution Approach 1:
The maneuvering operations are segmented into different categories (e.g., tight turns, wide turns, headland operations) with each category assigned to specific lifting positions. This segmentation allows the control system to handle complex maneuvering scenarios through modular classification rather than requiring a single complex continuous control algorithm
Solution Approach 2:
The control system automatically detects the maneuvering operation type and autonomously selects the appropriate lifting position from multiple predefined options without requiring manual intervention. This self-service capability improves field work efficiency by eliminating manual lifting operations while the predefined categorization keeps the control logic manageable
