Crop Transfer Synchronization Using Radar-Based Harvester Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The synchronization of agricultural harvesters and receiving vehicles during crop transfer operations is challenging due to limited visibility and the need for precise alignment, especially in conditions like dust or nighttime, which complicates the even filling of large grain bins and requires manual estimation by operators.
Innovation Solution
An agricultural crop receiving vehicle equipped with an electromagnetic detecting and ranging module generates data on the harvester's presence and location, allowing computing devices to control vehicle movement or provide a graphical user interface for precise alignment and fill level management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the receiving vehicle operator manually aligns the grain bin with the harvester spout during motion, then the unloading operation can proceed, but the operator effort and time required increase significantly, especially in conditions with limited visibility
Solution Approach 1:
The patent replaces the manual mechanical alignment process with an automated optical/electronic system. Sensors detect the relative position between the receiving vehicle and harvester, and the control system automatically adjusts the receiving vehicle's position and the grain bin's alignment, substituting human visual estimation and manual control with automated detection and control mechanisms.
Solution Approach 2:
The system creates a visual copy or representation of the physical alignment situation through displays and indicators that show the relative positions of the harvester and receiving vehicle. This allows the operator to see a graphical representation of the alignment status and makes informed decisions without directly observing the physical positions, especially useful in low visibility conditions.
2Productivity
If the receiving vehicle has a large or elongated grain bin to increase capacity, then the productivity improves, but the difficulty of evenly filling the bin increases because the operator cannot see into the bin to estimate fill pattern
Solution Approach 1:
The patent replaces the operator's visual estimation of fill level with automated sensing systems. Sensors (such as capacitive, optical, or radar sensors) detect the actual fill level and distribution of grain in the bin, providing precise measurement without requiring the operator to visually inspect the bin contents.
Solution Approach 2:
The system provides real-time feedback to the operator about the fill level and distribution of grain in the bin through displays and indicators. This feedback loop allows the operator to monitor the filling process and make adjustments to achieve even filling, transforming the previously open-loop estimation process into a closed-loop controlled process.
3Manufacturing precision
If the operator shifts the position of the grain bin during unloading to evenly fill the bin, then the fill uniformity improves, but the operational complexity and time required increase
Solution Approach 1:
The patent replaces manual position adjustment with automated position control. The control system receives input from sensors detecting fill uniformity and automatically adjusts the grain bin's position or the unloading rate, substituting the operator's manual shifting actions with automated mechanical control.
Solution Approach 2:
The system enables the unloading process to self-regulate for even filling through automated control. The control system monitors fill patterns and automatically makes adjustments without requiring continuous manual intervention, allowing the system to service itself in achieving uniform filling.

AI summary
A system includes an agricultural crop receiving vehicle with a bin for receiving and holding agricultural crop material and an electromagnetic detecting and ranging module for generating data indicating the presence and location of a harvester proximate the agricultural crop receiving vehicle. One or more one or more computing devices are configured to receive the data from the electromagnetic detecting and ranging module, determine a location of the harvester relative to the agricultural crop receiving vehicle, and use the location information to generate control signals for controlling movement of the agricultural crop receiving vehicle to coordinate receiving crop material in the bin from the harvester or for controlling a graphical user interface to present a visual indicator of the relative locations of the agricultural crop receiving vehicle and the harvester.
