Combine Harvester Route Control for Bidirectional Field Transfers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic run systems for work vehicles in farm fields are limited in creating discharge and return routes, as they can only be set for running in one direction, which restricts flexibility and efficiency in transferring between different positions within the farm field.
Innovation Solution
An automatic run method and system that allows for the creation of transfer routes and return routes capable of running in both forward and backward directions, enabling flexible and efficient transfers between transfer positions and target positions, such as discharge positions, within the farm field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If discharge route and return route are created for running in only one direction while avoiding unmown areas, then the work vehicle can safely transfer between positions, but the route creation flexibility and efficiency are limited
Solution Approach 1:
The route creation system dynamically determines running directions based on real-time field conditions. The automatic run control unit selectively creates discharge routes and return routes in forward or backward directions depending on the work vehicle's position, discharge position location, and unmown area distribution, transforming the static single-direction constraint into a dynamic multi-directional system that adapts to varying operational contexts
Solution Approach 2:
The system changes the directional parameter of route creation from fixed (single direction) to variable (forward or backward direction). By modifying the running direction parameter based on field conditions, the system achieves flexible route planning that can efficiently navigate around unmown areas while maintaining adaptability to different discharge position configurations
2Productivity
If discharge route and return route are created for running in only one direction, then the route creation process is simplified, but the efficiency of transferring between positions is reduced
Solution Approach 1:
The system dynamically selects between forward and backward running directions for discharge and return routes based on operational efficiency requirements. The automatic run control unit evaluates the work vehicle's current position, discharge position location, and field conditions to determine the optimal running direction, enabling efficient transfers while maintaining automated route creation without requiring complex manual intervention
Solution Approach 2:
The automatic run control unit autonomously determines and creates optimal discharge routes and return routes by self-evaluating field conditions and work vehicle position. The system performs self-service route planning that automatically adjusts running directions to maximize transfer efficiency without external intervention, achieving both high productivity and operational simplicity through automated decision-making
3Adaptability or versatility
If discharge route and return route are created for running in only one direction, then the control logic is simpler, but the ability to accommodate worker's intention and various target positions is limited
Solution Approach 1:
The automatic run control unit implements a universal route creation capability that handles multiple target positions (discharge positions, return positions) and accommodates various worker intentions through a single integrated system. The system can create discharge routes and return routes in either forward or backward directions, providing multi-functional adaptability that responds to different operational scenarios and worker preferences without requiring separate control mechanisms
Solution Approach 2:
The system dynamically adjusts route creation parameters including running direction, target position selection, and route configuration to accommodate worker intentions and various operational requirements. This dynamic adaptability enables the automated system to flexibly respond to different discharge position locations, work vehicle positions, and worker preferences while maintaining sophisticated automation through real-time parameter optimization

AI summary
A combine harvester includes a control device and a portable terminal. The control device functions as a discharge run control unit for doing an automatic discharge run based on a discharge route or a return run control unit for doing an automatic return run based on a return route. The portable terminal is provided with a control device, and the control device functions as a discharge route creation unit that creates a discharge route for doing an automatic discharge run in a non-work state from a given transfer position, where a work run is interrupted, to a discharge position as a target position, or a return route creation unit that creates a return route for doing an automatic return run in a non-work state from the discharge position as the given target position to a given return position for returning to the work run.
