Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for detecting plugging of agricultural implements during tillage operations are not sufficiently effective, particularly due to difficulties in determining when ground-engaging tools are plugged, often caused by dust accumulation.
Innovation Solution
A system comprising a radar sensor and a computing system that generates data indicative of soil flow and creates representations of this flow to determine when a ground-engaging tool is plugged, by removing components of the agricultural implement from the representation to focus on soil flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radar sensor data is processed to generate comprehensive soil flow representations, then detection accuracy improves, but computational resources and processing time increase
Solution Approach 1:
The system extracts and removes representations of agricultural implement components from the radar sensor data, isolating only the relevant soil flow information. This extraction process reduces computational complexity by eliminating unnecessary data elements while preserving the critical soil flow patterns needed for accurate plugging detection.
Solution Approach 2:
The processing system segments the radar sensor data into distinct components: soil flow representations and implement component representations. By separating these elements and selectively processing only the soil flow data for plugging detection, the system achieves accurate detection with reduced computational burden and faster processing times.
2Measurement precision
If comprehensive soil flow data is analyzed, then plugging detection accuracy improves, but computational resources required increase
Solution Approach 1:
The computing system extracts only the essential soil flow information from the complete radar dataset, removing representations of implement components and other non-essential elements. This selective extraction maintains detection accuracy by preserving critical soil flow patterns while significantly reducing the computational energy required to process and analyze the data.
3Difficulty of detecting and measuring
If dust is present in the field environment, then operator ability to detect plugging deteriorates, but radar sensor performance remains unaffected
Solution Approach 1:
The system replaces visual detection methods with radar-based detection. The radar sensor emits electromagnetic waves that penetrate dust particles, allowing the system to detect soil flow patterns and identify plugging conditions regardless of dust concentration. This substitution of detection mechanism eliminates the reliability issues associated with visual detection in dusty environments.

AI summary
A system for detecting plugging of an agricultural implement includes a ground-engaging tool configured to be moved through soil and a radar sensor configured to generate data indicative of the flow of the soil in the portion of the field through which the tool is moving. The system also includes a computing system configured to receive the radar sensor data indicative of the flow of the soil and generate a representation of the flow of the soil based on the received radar sensor data. Additionally, the computing system is configured to remove one or more components of the agricultural implement from the generated representation such that a modified representation of the flow of the soil in the portion of the field through which the ground-engaging tool is moving is created. Furthermore, the computing system is configured to determine when the tool is plugged based on the generated modified representation.
