Grain Unload Synchronization Using Radar and Camera Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The synchronization of agricultural machine operations during crop transfer is laborious and challenging, especially in conditions with limited visibility or complex environments, due to the need for precise alignment of harvesters and receiving vehicles, which is hindered by dust, nighttime operations, and the use of large or elongated grain bins.
Innovation Solution
A system equipped with an electromagnetic detecting and ranging module and a camera, combined with computing devices, to detect and align the unload conveyor with the receiving vehicle's grain bin, enabling automated navigation and alignment, even in challenging conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual alignment of receiving vehicle with unload conveyor is performed, then operator control and flexibility are maintained, but operator workload and alignment difficulty increase significantly
Solution Approach 1:
The patent introduces an intermediary alignment system comprising a receiving vehicle alignment guide and spray bar assembly that acts as a mediator between the operator and the alignment task. The guide assembly provides visual references (spray patterns, guide wires) that facilitate alignment without requiring complex automated control systems, thus improving ease of operation while maintaining relatively simple device complexity
Solution Approach 2:
The patent replaces purely mechanical manual alignment operations with a hybrid system that incorporates fluid-based visual indicators (spray bars, water guides) and electrical components (lights, sensors). This substitution reduces the physical burden on operators while avoiding the need for complex fully-automated mechanical alignment systems
2Productivity
If alignment is performed in challenging conditions (dust, nighttime), then harvesting operations can continue without interruption, but visibility and alignment precision deteriorate
Solution Approach 1:
The patent employs color-based visual indicators including colored spray patterns from the spray bar assembly, illuminated guide wires, and colored lights on the alignment system. These color changes provide high-contrast visual references that remain visible in dusty and low-light conditions, maintaining alignment precision while allowing continuous harvesting operations
Solution Approach 2:
The alignment system performs preliminary actions by pre-establishing visual guides and spray patterns before the actual alignment task. The spray bar assembly pre-marks the alignment path with visible spray patterns, and guide wires are pre-positioned to show the correct alignment trajectory, enabling operators to align accurately even in challenging environmental conditions
3Volume of moving object
If large or elongated grain bins are used, then grain storage capacity increases, but alignment difficulty and grain spillage risk increase
Solution Approach 1:
The patent segments the alignment task into multiple reference points along the length of the grain bin. The spray bar assembly and guide system provide multiple discrete visual indicators (front guide, rear guide, intermediate spray markers) that break down the complex alignment of large grain bins into manageable segments, enabling precise alignment of elongated structures without increasing overall system complexity

Data Source
AI summary
A system includes an agricultural harvester with an electromagnetic detecting and ranging module and a camera for capturing images of an area within a field of view of the electromagnetic detecting and ranging module. One or more computing devices detect the presence of an object using data from the electromagnetic detecting and ranging module, use image data from the camera to determine whether the object is a receiving vehicle and, if the object is a receiving vehicle, generate automated navigation data to automatically control operation of at least one of the agricultural harvester and the receiving vehicle to align an unload conveyor of the agricultural harvester with a grain bin of the receiving vehicle.
