Agricultural Component Position Imaging for Timed Mechanism Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural machines with timed mechanisms face challenges in accurately and efficiently evaluating the time-dependent positioning of traveling components, such as hay needles, due to their complex motion paths and synchronized operations, leading to potential mispositioning and improper knot formation in large square balers.
Innovation Solution
An image-based position assessment method using a diagnostic camera mounted on the agricultural machine to capture images of the traveling components, with an image processing system analyzing these images to determine if the components deviate from their expected positions, and generating notifications for necessary adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If routine manual inspection methods are used to evaluate traveling component positioning, then operational simplicity is maintained, but measurement precision and evaluation accuracy deteriorate
Solution Approach 1:
The patent replaces manual mechanical inspection methods with an automated optical imaging system. A camera captures images of the traveling component at specific positions, and an image processing system automatically analyzes these images to determine component positioning accuracy. This substitution of mechanical/manual inspection with optical-electronic systems resolves the contradiction by providing high measurement precision through automated image analysis while keeping the overall device complexity manageable through standardized imaging components.
2Adaptability or versatility
If complex timed mechanisms with multiple synchronized components are used, then functional capability is improved, but reliability of component positioning deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the image processing system continuously monitors the positioning of traveling components and provides diagnostic information about deviations from expected positions. This feedback allows for real-time assessment of component synchronization and positioning accuracy, enabling operators to detect and correct positioning errors before they compromise mechanism reliability. The system captures images at predetermined positions and compares actual component locations against expected positions, providing actionable feedback for maintaining reliable operation.
3Productivity
If manual inspection and maintenance procedures are used, then equipment cost is reduced, but productivity and operational efficiency deteriorate
Solution Approach 1:
The patent enables the system to perform self-diagnosis and self-assessment of component positioning. The automated image capture and analysis system allows the agricultural machine to monitor its own component positioning without requiring external manual inspection. This self-service capability significantly improves productivity by enabling rapid assessment of component positions and reducing maintenance downtime, while the cost is offset by eliminating labor-intensive manual inspection procedures and preventing costly failures through early detection of positioning deviations.

AI summary
An image-based position assessment method is performed in conjunction with a mechanism onboard an agricultural machine and containing a traveling component. In embodiments, the method includes receiving, at an image processing system, camera images captured by a diagnostic camera mounted to the agricultural machine. A field of view of the diagnostic camera at least partially encompasses an intended motion path along which the traveling component is configured to travel. The image processing system analyzes the camera images to determine whether a recorded time-dependent component position of the traveling component deviates excessively from an expected time-dependent component position of the traveling component, as taken along the intended motion path. The image processing further generates, or causes generation of, a first notification on a display device indicating that a positional adjustment to the traveling component is recommended if the recorded time-dependent component position deviates excessively from the expected time-dependent component position.
