RFID Tagged Container Tracking for Agricultural Product Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current closed container systems for agricultural products lack efficient tracking and authentication mechanisms for user authorization, product quantity, and geographic location monitoring, leading to potential contamination, misuse, and inefficiencies in product dispensing and refilling.
Innovation Solution
A system utilizing RFID tags and computer processors to authenticate users and track product use by reading and updating identity data, preventing unauthorized dispensing, monitoring product quantity, and generating maps of product application, ensuring only authorized use and efficient refilling based on actual usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual tracking and authentication methods are used for closed container systems, then device complexity is reduced, but productivity and measurement precision deteriorate due to inefficiencies in product dispensing tracking and user authorization verification
Solution Approach 1:
The patent replaces manual tracking and authentication mechanisms with an automated RFID-based system. RFID tags attached to containers and dispensing equipment enable automatic identification, authentication, and tracking without manual intervention, thereby improving productivity while the modular system design keeps complexity manageable
Solution Approach 2:
The system uses RFID tags that create digital copies/representations of container identity, product information, and authorization data. These digital copies enable rapid automated verification and tracking without requiring physical inspection or manual record-keeping, enhancing dispensing efficiency
2Reliability
If no authentication mechanism is implemented, then ease of operation is improved, but reliability deteriorates due to potential unauthorized dispensing and misuse
Solution Approach 1:
The system performs preliminary authentication via RFID verification before allowing product dispensing. User credentials and container authorization are verified in advance, ensuring reliability and preventing unauthorized use, while the automated nature of this preliminary check minimizes impact on operational simplicity
Solution Approach 2:
The RFID authentication system acts as an intermediary between the user and the dispensing mechanism. It mediates the authorization process by verifying credentials and controlling valve activation, ensuring reliable authorized use while maintaining ease of operation through automated intermediary verification
3Loss of substance
If product quantity is not monitored, then device complexity is reduced, but loss of substance increases due to inability to track actual usage and prevent contamination
Solution Approach 1:
The system implements feedback through RFID tracking that continuously monitors product quantity in containers. This feedback enables real-time tracking of dispensing amounts, automatic update of inventory records, and prevention of over-dispensing or contamination, reducing substance loss while the automated feedback loop manages monitoring complexity efficiently
Solution Approach 2:
The RFID system enables self-service tracking where the monitoring system automatically records product quantity changes, updates inventory databases, and generates usage reports without manual intervention. This self-service capability reduces substance loss through automated monitoring while keeping the system relatively simple
4Loss of information
If geographic location is not tracked, then device complexity is reduced, but loss of information increases due to inability to generate product application maps and track dispensing locations
Solution Approach 1:
The system merges RFID container identification with GPS location tracking into a unified tracking system. This combination enables automatic generation of product application maps that correlate dispensing events with geographic locations, preventing information loss while the integrated design manages system complexity efficiently
Solution Approach 2:
The RFID tracking system serves multiple functions simultaneously: it authenticates users, tracks product quantity, records dispensing events, and captures geographic location data. This multi-functionality ensures comprehensive information capture without requiring separate dedicated systems, reducing information loss while managing complexity

AI summary
A system and method that automatically monitors product use, such as the type and amount of agricultural and/or horticultural product stored in and dispensed from a cartridge over time and/or by geographic location. Monitored data are stored in memory such as a tag on the cartridge and may be transmitted to a server for storage, aggregation, and analysis. The cartridge may be authenticated before being authorized for use for the benefit of a current user in dispensing the product. The cartridge may be refilled after confirmation of authorization codes on the cartridge and refilling equipment tags. The cartridge may be calibrated automatically based on the bulk density or other parameter of the product in the cartridge. Data may be aggregated from a plurality of cartridges automatically. As-applied data from individual cartridges may be used to verify, independent of operator input, treated area coverage and product application rate.
