Seeder Metering Calibration via Wireless Console
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current metering systems in air seeders require frequent and error-prone calibration, especially when dispensing multiple products, as operators must repeatedly travel between the seeder and tractor cab to adjust settings, leading to inefficiencies and potential errors due to the complexity of manual calculations and the need for precise weight measurements.
Innovation Solution
A calibration device with a portable electrical harness and consoles that allows for on-site calibration near the metering system, enabling operators to input weight measurements directly into a console connected to the metering system, which calculates and adjusts the dispensing rate, reducing the need for frequent trips to the tractor cab and minimizing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If calibration is performed using traditional methods requiring trips to the tractor cab, then operators can access the calibration console, but this increases time consumption and potential for errors
Solution Approach 1:
The patent introduces a wireless communication dimension to the calibration process. The mobile computing device communicates with the metering system via wireless signals, allowing operators to perform calibration operations remotely from the field rather than physically traveling to the tractor cab. This spatial dimensionality change eliminates time loss while maintaining calibration precision.
Solution Approach 2:
The mobile computing device serves as an intermediary between the operator and the metering system calibration console. It receives calibration data from sensors, performs calculations, and transmits adjusted settings back to the metering system, enabling remote calibration operations without direct physical access to the original console.
2Adaptability or versatility
If multiple products are dispensed, then crop production flexibility is improved, but calibration complexity and error potential increase
Solution Approach 1:
The mobile computing device performs multiple calibration functions for different products through a single unified interface. It can calculate and adjust calibration settings for seed, fertilizer, and other agricultural products by receiving product-specific data from sensors and applying appropriate calibration algorithms, eliminating the need for separate calibration systems for each product type.
Solution Approach 2:
The system incorporates real-time feedback loops where sensors continuously monitor product flow rates and the mobile computing device receives this data, performs calculations, and automatically adjusts metering system settings. This closed-loop feedback mechanism simplifies multi-product calibration by automatically adapting settings based on actual measured performance rather than requiring manual calculations for each product.
3Ease of operation
If manual calculations are used for calibration, then operators can understand the calibration process, but calculation errors and measurement inaccuracies increase
Solution Approach 1:
The patent replaces manual calculation operations with automated electronic computation performed by the mobile computing device. Sensors automatically measure product flow parameters, the device's processor performs calibration calculations using stored algorithms, and results are transmitted back to the metering system. This substitution of mechanical/manual operations with electronic automation eliminates calculation errors while maintaining operational understanding through the device's interface.

AI summary
A calibration device for calibrating a metering system that dispenses a product to a seeder towed by a farm vehicle is provided for obtaining and maintaining a desired rate of delivery of the product from the seeder. The calibration device includes a first console port positioned at or near the farm vehicle and a second console port at or near the metering system, each operative to receive at least one a calibration console for calibrating the rate of product delivery and adjust the metering system accordingly.
