Combine Harvester Field Area Setting for Complete Auto Reaping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Combine harvesters face issues with creating automatic traveling routes in fields, leading to unworked regions and resulting in work remaining areas when trying to perform automatic reaping traveling along the periphery of the creation-capable area.
Innovation Solution
An area setting method and system that includes an outline setting step for the field outline, a creation-capable area setting step within the field outline, and a range changing step to adjust the creation-capable area, ensuring no unworked regions are left and allowing for seamless automatic traveling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the combine harvester performs manual reaping traveling around the periphery of the target creation-capable area, then the outer periphery of the field is worked, but the unworked region may be left protruding from the creation-capable area causing work remaining areas
Solution Approach 1:
The patent applies dynamics by making the creation-capable area dynamically adjustable. The system automatically expands or contracts the creation-capable area based on the actual working progress and the position of unworked regions. This allows the area boundary to adapt in real-time, ensuring that protruding unworked regions are incorporated into the creation-capable area, thereby eliminating work remaining areas and improving area coverage accuracy.
Solution Approach 2:
The patent implements feedback by continuously monitoring the working progress and the position of unworked regions relative to the creation-capable area. When unworked regions are detected to protrude from the creation-capable area, the system provides feedback to automatically adjust the area boundary, ensuring complete coverage and preventing work remaining areas.
2Extent of automation
If the creation-capable area is set to exclude the outer periphery for manual working, then automatic traveling can be implemented in the main area, but unworked regions remain that cannot be covered by automatic traveling
Solution Approach 1:
The system dynamically adjusts the creation-capable area to include unworked regions when they protrude from the original boundary. This dynamic adjustment ensures that the automatic traveling system can cover the entire field area, including regions that were initially excluded, thereby achieving complete area coverage while maintaining automatic traveling capability.
Solution Approach 2:
The patent applies preliminary action by pre-defining the creation-capable area to exclude the outer periphery, allowing manual working to be performed first. After manual working, the system automatically adjusts the creation-capable area to include any unworked regions, ensuring that subsequent automatic traveling can cover the entire area without leaving work remaining areas.

AI summary
A work vehicle, such as a combine harvester, includes a portable terminal, and the portable terminal comprises a control device. The control device functions as an outline setting section for setting a field outline, a creation-capable area setting section for setting a creation-capable area that is provided inside the field outline and in which an automatic traveling route can be created, and a range changing section for changing a range of the creation-capable area.
