Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Farmers face challenges in detecting plugging conditions of ground-engaging tools, such as rolling basket assemblies, during tillage operations, as it is difficult to visually assess the tools from the operator's cab.
Innovation Solution
An agricultural system that includes a plugging sensor positioned within the basket assembly, capable of transmitting detection signals at different frequencies and generating data based on return signals, which is then processed by a computing system to determine if the basket assembly is plugged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operator visually inspects the basket assembly from the cab, then the operator can detect plugging conditions, but the inspection time and effort increase significantly
Solution Approach 1:
The basket assembly performs self-diagnosis through integrated sensors that automatically detect plugging conditions. The sensor system monitors the basket's operational state and generates alerts without requiring operator intervention or visual inspection, enabling the system to service itself by identifying its own problems.
Solution Approach 2:
The manual visual inspection process is replaced with an automated sensor-based detection system. Electromagnetic sensors, accelerometers, and other electronic devices substitute for the operator's visual assessment, transforming a manual mechanical inspection task into an automated electronic monitoring system that continuously tracks basket conditions.
2Reliability
If the operator continuously monitors the basket assembly, then plugging conditions are detected early, but the operator's attention and time are consumed
Solution Approach 1:
The sensor system continuously monitors basket assembly conditions and provides real-time feedback to the operator through displays or alerts. This automated feedback loop enables early detection of plugging conditions while freeing the operator from continuous manual monitoring, as the system independently tracks and reports abnormal conditions.
Solution Approach 2:
The monitoring function is transferred from the operator to the sensor system, which autonomously detects and reports plugging conditions. The system serves itself by automatically identifying problems and communicating their status, eliminating the need for operator attention and reducing workload while maintaining early detection capability.
3Productivity
If manual inspection methods are used, then the system complexity remains low, but the productivity and efficiency of tillage operations decrease
Solution Approach 1:
Manual inspection processes are replaced with automated sensor-based monitoring systems that use electromagnetic fields, acoustic waves, and electronic signal processing to detect plugging conditions. This substitution dramatically improves productivity by enabling continuous monitoring without adding significant operational complexity, as the electronic systems integrate seamlessly with existing basket assembly structures.

Data Source
AI summary
An agricultural system for monitoring plugging of basket assemblies of an agricultural implement includes a plugging sensor positioned within an interior of a monitored basket assembly, where the plugging sensor is configured to transmit detection signals at different frequencies across a field of detection along the interior of the basket assembly and along the rotational axis, and generate data indicative of return signals received based on reflection of the detection signals at the different frequencies off at least one surface. Additionally, the agricultural system includes a computing system configured to receive the data generated by the plugging sensor and determine when the basket assembly is experiencing a plugged condition based at least in part on the data generated by the plugging sensor.
