Agricultural Harvester Collaborative Residue Spread Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional agricultural harvester systems fail to accurately detect and adjust residue spread performance due to interference from dust and debris, leading to non-uniform residue coverage, which affects crop development, pest distribution, and harvesting efficiency.
Innovation Solution
A collaborative system where one agricultural harvester detects the residue spread performance of another using remote sensors, transmitting feedback to adjust operation parameters to improve residue spread uniformity and coverage, using processing circuitry and communication links to modify parameters such as spreader speed and angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional sensors are used to detect residue spread performance, then the detection system is simple, but the detection accuracy deteriorates due to dust and debris interference
Solution Approach 1:
The patent uses a remote sensor mounted on a second harvester as an intermediary device to detect residue spread from the first harvester. This remote sensing approach allows the detection system to obtain accurate residue spread measurements without being directly exposed to dust and debris generated by the first harvester, thus maintaining high detection accuracy while avoiding harmful environmental factors.
2Manufacturing precision
If real-time feedback control is implemented, then residue spread uniformity is improved, but system complexity increases
Solution Approach 1:
The patent implements a feedback control system where the remote sensor continuously monitors residue spread performance and transmits data to the controller. The controller processes this feedback information and automatically adjusts operation parameters (such as spreader speed, elevation, or angle) to maintain uniform residue distribution. This closed-loop feedback mechanism improves residue spread uniformity while managing system complexity through automated control.
3Measurement precision
If collaborative detection between harvesters is used, then detection accuracy is improved, but the number of required sensors increases
Solution Approach 1:
The patent merges the detection function into the second harvester's existing sensor system rather than adding dedicated sensors to the first harvester. The second harvester uses its own sensors to detect residue spread from the first harvester, thereby improving detection accuracy through remote measurement while avoiding the need to multiply the total number of sensors across the system.
