Sequential Control of Agricultural Ground-Engaging Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural systems lack the ability to automatically and effectively adjust operating parameters of ground-engaging tools in real-time based on varying field conditions, leading to suboptimal tillage operations and seedbed preparation.
Innovation Solution
A system comprising sensors and a controller that determine field characteristics and adjust the operating parameters of multiple ground-engaging tools, such as leveling blades and shanks, to optimize soil preparation by iteratively adjusting their penetration depth and force based on real-time data from sensors like LIDAR and draft load sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual adjustment of ground-engaging tools is used, then system complexity is reduced, but manufacturing precision and adaptability to varying field conditions deteriorate
Solution Approach 1:
The system employs sensors (LIDAR, draft load sensors) to continuously monitor field conditions and tool performance, feeding this data back to the controller which automatically adjusts operating parameters of ground-engaging tools to maintain optimal seedbed preparation
Solution Approach 2:
The control system automatically adjusts tool operations without requiring manual intervention, with the controller independently processing sensor data and modifying tool parameters based on real-time field conditions
2Productivity
If single-pass tillage is attempted without sequential control, then productivity increases, but manufacturing precision deteriorates due to inability to adapt to varying field conditions
Solution Approach 1:
The system dynamically adjusts operating parameters of multiple ground-engaging tools in sequence during a single pass, with the controller modifying penetration depth, force, and other parameters based on real-time sensor feedback to maintain optimal performance across varying field conditions
Solution Approach 2:
The tillage operation is divided into multiple sequential stages with different ground-engaging tools (e.g., leveling blades first, then shanks), each independently controlled based on sensor data to progressively achieve the desired seedbed condition in one field pass
3Manufacturing precision
If multiple tillage passes are performed without automated control, then manufacturing precision improves, but productivity and loss of time worsen
Solution Approach 1:
The system maintains continuous monitoring and adjustment throughout the tillage operation, with sensors continuously capturing field condition data and the controller continuously modifying tool parameters to achieve optimal seedbed preparation in a single uninterrupted pass
4Adaptability or versatility
If automated control of multiple tools is implemented, then adaptability to field conditions improves, but device complexity increases
Solution Approach 1:
A single controller unit manages multiple ground-engaging tools and processes data from various sensors (LIDAR, draft load sensors), providing multi-functional capability that adapts to different field conditions without requiring separate control systems for each tool

AI summary
In one aspect, a system for controlling ground-engaging tools of an agricultural implement may include first and second ground-engaging tools configured to perform first and second operations, respectively, on a field as the agricultural implement is moved across the field. Furthermore, a controller of the disclosed system may be configured to determine a first value of a field characteristic based on the received sensor data and adjust an operating parameter of the first ground-engaging tool based on the determined first value. After adjusting the operating parameter of the first ground-engaging tool, the controller may be configured to determine a second value of the field characteristic based on the sensor data and adjust an operating parameter of the second ground-engaging tool based on the determined second value.
