Combine Harvester Area Setting for Complete Auto-Reaping Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Combine harvesters face issues with creating automatic traveling routes in fields, leading to unreaped areas when manual reaping around the periphery is incomplete, resulting in work remaining areas.
Innovation Solution
An area setting method and system that includes an outline setting step, a creation-capable area setting step, and a range changing step to ensure no work remaining area occurs by adjusting the creation-capable area based on field outlines and reaping patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual reaping traveling is performed around the periphery of the field to reach the creation-capable area, then the combine harvester can prepare for automatic reaping, but the combine harvester cannot travel along the outer periphery of the creation-capable area, resulting in unworked regions protruding from the creation-capable area
Solution Approach 1:
The system performs preliminary actions by setting the creation-capable area range before automatic reaping traveling begins. The range setting section establishes the boundaries of the creation-capable area based on field outline information, ensuring that the automatic traveling route will cover the entire area without leaving unworked regions. This preliminary area definition prevents the problem of unworked regions protruding from the creation-capable area.
Solution Approach 2:
The system uses feedback by comparing the field outline with the manually reaped area to determine the optimal creation-capable area range. The range setting section adjusts the creation-capable area boundaries based on feedback from the manual reaping operation, ensuring that the automatic traveling route will seamlessly cover all remaining unworked regions without leaving gaps.
2Productivity
If automatic reaping traveling is performed in the creation-capable area with unworked regions protruding, then automatic reaping can proceed, but work remaining areas occur where crops are not reaped
Solution Approach 1:
The system performs preliminary actions by pre-defining the creation-capable area range to exactly match the boundaries of manually reaped regions. The range setting section calculates the optimal creation-capable area based on field outline information and manual reaping progress, ensuring that the automatic traveling route will cover the entire remaining area without leaving unworked regions. This preliminary area definition guarantees complete coverage and eliminates work remaining areas.
3Device complexity
If the creation-capable area is set without adjusting the range, then the area setting process is simple, but work remaining areas occur when manual reaping does not reach the optimal boundary
Solution Approach 1:
The system applies dynamics by making the creation-capable area range adjustable and adaptable. The range setting section dynamically determines the creation-capable area boundaries based on field outline information and manual reaping progress, allowing the area range to be optimized for each specific field condition. This dynamic range adjustment ensures accurate boundary definition without requiring complex manual configuration, resolving the contradiction between simplicity and precision.
