Agricultural Control Assembly Direction-Based Triggering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control devices for agricultural working machines struggle to determine whether a control sequence can be triggered, especially in situations where manual steering is required and space for turning is limited, leading to uncertainty about when to execute control sequences near the headland or crop boundary.
Innovation Solution
A control device that considers both the position and direction of travel of the working machine to determine the triggerability of a control sequence, providing a permissible area for execution and visual feedback to the operator, allowing for precise manual steering and preventing unintentional triggering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If control sequences are triggered based only on position and area information, then the control device can operate with simpler logic, but the triggerability determination becomes inaccurate when the working machine is manually steered and direction of travel is not considered
Solution Approach 1:
The control device determines the permissible area in advance based on the control sequence requirements and working machine parameters. This pre-calculated area information is stored and later used for rapid triggerability assessment, avoiding complex real-time calculations while maintaining accuracy.
Solution Approach 2:
The control device continuously monitors the working machine position, direction of travel, and compares it against the predetermined permissible area. This feedback mechanism enables accurate triggerability determination by checking whether current operational parameters fall within the acceptable range defined by the permissible area.
2Extent of automation
If the control device triggers control sequences based on predetermined distances from headland point, then automation is improved, but uncertainty arises when manual steering is used and the working machine may not reach expected distances or may approach from unsuitable directions
Solution Approach 1:
The control device dynamically adjusts control sequence triggering by continuously evaluating both position and direction of travel against the permissible area. This dynamic assessment adapts to manual steering variations, ensuring reliable triggerability determination regardless of whether the working machine follows automated or manual pathing.
Solution Approach 2:
The invention changes the assessment parameters from solely distance-based to include directional orientation. By incorporating direction of travel as a critical parameter alongside position, the system reliably determines triggerability even when manual steering causes deviations from predetermined paths or distances.
3Ease of operation
If control sequences are triggered without considering direction of travel, then the control device operates more simply, but unintentional triggering may occur when the working machine drives along the crop boundary without intending to transition to headland
Solution Approach 1:
The permissible area is predetermined based on control sequence requirements and working machine parameters before operation begins. This pre-established geometric reference enables simple real-time checking by comparing current position and direction against the stored permissible area, maintaining operational simplicity while preventing unwanted triggering.
Solution Approach 2:
The control device uses feedback from both position and direction of travel sensors to continuously assess whether the working machine is within the permissible area for control sequence triggering. This dual-parameter feedback prevents unintentional triggering by ensuring both location and orientation meet criteria before activation.
