Agricultural Implement Controller for Soil Moisture-Based Depth Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Farmers face challenges in accurately determining soil moisture content across a field, leading to inconsistent seedbed quality and reduced crop yields due to varying soil and crop conditions, as they rely on experience rather than precise data for setting tillage implement penetration depths.
Innovation Solution
A system and method that utilize a controller to receive data on field characteristics, determine soil moisture content at multiple depths, and adjust the operation of agricultural implements, such as tillage tools, based on these values to optimize penetration depth and improve seedbed preparation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operators rely on experience or instinct to set penetration depth, then operation simplicity is maintained, but manufacturing precision of seedbed quality deteriorates
Solution Approach 1:
The patent replaces the manual mechanical approach of setting penetration depth based on operator experience with an automated electronic control system. The system uses soil moisture sensors to detect soil conditions and automatically adjusts the penetration depth of tillage tools through electronic control, eliminating the need for operators to rely on instinct while achieving consistent seedbed quality
Solution Approach 2:
The system dynamically changes the penetration depth parameter based on real-time soil moisture content measurements. By continuously monitoring soil moisture levels and adjusting penetration depth accordingly, the system adapts to varying field conditions to maintain optimal seedbed quality without requiring manual intervention
2Adaptability or versatility
If operators manually adjust penetration depth for varying field conditions, then adaptability improves, but loss of time increases
Solution Approach 1:
The system performs self-adjustment by automatically monitoring soil moisture conditions and modifying penetration depth without operator intervention. The automated control system handles the adaptation to varying field conditions independently, eliminating the time operators would spend making manual adjustments while maintaining full adaptability
Solution Approach 2:
The system implements continuous feedback through soil moisture sensors that monitor field conditions and automatically adjust penetration depth in real-time. This closed-loop control enables the system to adapt to varying soil conditions throughout the field without requiring manual intervention, saving time while maintaining adaptability
3Device complexity
If uniform penetration depth is used across the field, then device complexity is reduced, but manufacturing precision of seedbed quality deteriorates due to varying soil conditions
Solution Approach 1:
The patent transitions from a static, uniform penetration depth setting to a dynamic adjustment system that continuously modifies penetration depth based on real-time soil moisture measurements. This dynamic approach allows the system to adapt to varying field conditions while maintaining relatively simple sensor and control mechanisms
Solution Approach 2:
The system applies different penetration depth settings to different locations within the field based on local soil moisture conditions. By monitoring and adjusting penetration depth for each specific location rather than using a uniform setting, the system achieves consistent seedbed quality across varying field conditions without requiring complex overall system design

AI summary
In one aspect, a system for controlling the operation of an agricultural implement may include an agricultural implement configured to perform an agricultural operation on a field as the implement is moved across the field. A controller of the system configured to receive data indicative of a plurality of field characteristics of the field. The controller may also be configured to determine first and second soil moisture content values of the soil within the field at first and second depths below a field surface of the field based on the received data, respectively. Additionally, the controller may be configured to initiate adjustment of an operating parameter of the agricultural implement based on the determined the first soil moisture content value and the determined second soil moisture content value.
