Disc Blade Status Detection Using Trace Comparison in Tillage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural tillage implements with disc blades often suffer from broken or missing blades due to soil contact, leading to uneven tillage and reduced efficiency, which is typically detected through time-consuming manual inspection.
Innovation Solution
A detection system equipped with sensors and a controller that generates sensor data to determine the operational status of disc blades by comparing their traces to target traces, allowing for real-time identification of impaired blades and automatic operation cessation.

Engineering Contradiction Analysis
1Ease of manufacture
If manual inspection is used to detect broken or missing disc blades, then the detection method is simple and requires no additional equipment, but the operation must be stopped for a period of time and the process is time-consuming
Solution Approach 1:
The patent replaces manual mechanical inspection with an automated optical sensing system. Sensors capture images of disc blades during operation, and a controller automatically analyzes the images to detect broken or missing blades, eliminating the need to stop operations for manual inspection.
Solution Approach 2:
The detection system enables the tillage implement to self-monitor its own operational status. The sensor and controller work autonomously to detect blade conditions without requiring operator intervention or stopping the equipment, allowing continuous operation with real-time monitoring.
2Device complexity
If manual inspection is performed to detect impaired disc blades, then no additional detection equipment is needed, but the detection process is time-consuming and reduces productivity
Solution Approach 1:
Manual inspection is replaced with an automated optical detection system consisting of sensors and a controller. The system continuously monitors disc blade conditions during operation, enabling real-time detection without stopping work, thereby maintaining high productivity while providing reliable detection.
Solution Approach 2:
The detection system operates continuously during tillage operations without interrupting the workflow. Sensors continuously capture blade images and the controller continuously analyzes them, ensuring uninterrupted monitoring and maintaining continuous productive operation.
3Reliability
If continuous monitoring of disc blades is implemented, then real-time detection of impaired blades is achieved, but the system complexity and cost increase
Solution Approach 1:
The patent uses optical sensors and image processing algorithms to detect blade conditions, replacing complex mechanical monitoring systems. The sensor captures images and the controller analyzes them using pattern recognition, providing reliable detection with relatively simple electronic components.
Solution Approach 2:
The system creates optical copies (images) of the disc blades and analyzes these copies to determine blade status. This allows detection without physical contact or complex mechanical interaction with the moving blades, simplifying the detection mechanism while maintaining reliability.

AI summary
A control system for an agricultural implement may include a sensor that generates sensor data for a disc blade and a controller communicatively coupled to the sensor and comprising a memory and a processor. The controller performs operations including receive the sensor data from the sensor, determine a trace based on the sensor data, and determine a status of the disc blade based on a comparison of the trace to a target trace. The status includes operational or not operational.
