Combine Harvester Block Allocation for Capacity-Matched Field Work
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional work vehicle systems in farm fields sectionalize the area without considering the work capacity of each vehicle, leading to reduced travel and work efficiency as vehicles often operate below their capacity in separated sections.
Innovation Solution
A method and system that divide the farm field into work blocks based on the work vehicles' capacities, allocating each vehicle to a block to optimize their work efficiency, using a work allocator and self-driving controller to manage and perform tasks within allocated blocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the farm field is sectionalized into multiple sections to separate work vehicles, then collision between vehicles is prevented, but work capacity utilization is reduced
Solution Approach 1:
The patent divides the work area into multiple work blocks and assigns different vehicles to different blocks, creating spatial segmentation that prevents collisions while allowing each vehicle to operate at full capacity in its designated block
Solution Approach 2:
The patent assigns work blocks with different characteristics (size, crop type, terrain) to vehicles based on their specific work capacities and capabilities, ensuring each vehicle operates in an environment optimized for its performance
2Ease of operation
If work vehicles are assigned to fixed sections, then work coordination is simplified, but travel efficiency is reduced
Solution Approach 1:
The patent implements dynamic work block assignment where vehicles can be reassigned to different work blocks based on real-time conditions, work progress, and vehicle availability, allowing flexible coordination without fixed section constraints

AI summary
A combine harvester that works in a farm field in cooperation with a combine harvester is a work vehicle capable of automatically traveling based on a travel path created in the farm field, and includes a portable terminal that functions as a work allocator that divides a work area of the farm field into a plurality of work blocks based on the combine harvesters and, and allocates any of the combine harvesters and, and a controller that functions as a self-driving controller that performs a work of the work blocks' work block allocated to combine harvester.
