A transportation and storage device equipped with RFID technology, GPS, and a mobile app that uses QR codes to automate inventory tracking, invoicing, and restocking, ensuring real-time monitoring and accurate record-keeping of medical devices, including implants and instruments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual inventory tracking by sales representatives is used, then flexibility in handling inventory is maintained, but accuracy and reliability of inventory tracking deteriorates due to human errors
Solution Approach 1:
The patent replaces manual mechanical inventory tracking with an automated RFID-based electronic system. RFID tags on medical devices communicate wirelessly with readers at storage locations, automatically tracking inventory movements without human intervention. This substitution eliminates human errors in tracking while maintaining operational flexibility.
Solution Approach 2:
The system enables self-service inventory tracking where medical devices automatically report their location and status through RFID technology. The inventory system autonomously monitors stock levels, tracks movements, and generates reordering notifications without requiring manual checking or sales representative intervention, thereby improving reliability while reducing operational complexity.
2Productivity
If manual invoicing processes are used, then simplicity of the process is maintained, but productivity and billing efficiency deteriorates
Solution Approach 1:
The system performs preliminary actions by automatically recording inventory movements and usage data in real-time through RFID tracking. This preliminary data collection eliminates the need for manual invoicing processes, as the system already has complete information about what was used, when, and where. Billing is generated automatically from this pre-collected data, significantly improving productivity.
Solution Approach 2:
The system implements continuous feedback loops where RFID readers constantly monitor inventory levels and usage patterns. This feedback data is automatically processed to trigger invoicing procedures and restocking notifications. The automated feedback mechanism ensures timely billing without manual intervention, improving billing efficiency while the integrated nature of the system keeps overall complexity manageable.
3Productivity
If manual restocking processes are used, then ease of operation is maintained, but loss of time and productivity deteriorates
Solution Approach 1:
The RFID system provides continuous monitoring of inventory levels and device movements without interruption. Readers continuously scan for tag signals, automatically detecting when inventory is depleted or needs restocking. This continuous action eliminates downtime for manual counting and monitoring, maintaining productive operations while rapidly responding to restocking needs.
Solution Approach 2:
The system performs self-service restocking by automatically detecting low inventory levels and generating reordering notifications when thresholds are breached. The automated system monitors stock levels continuously and initiates restocking procedures without human intervention, significantly reducing the time required for inventory monitoring and improving overall restocking speed.
4Measurement precision
If RFID scanning is performed continuously, then measurement precision of inventory tracking is improved, but use of energy and device complexity increases
Solution Approach 1:
The RFID system employs periodic scanning rather than continuous operation. Readers are activated at specific intervals or triggered by events such as door openings, device movements, or scheduled inventory checks. This periodic action maintains high measurement precision for inventory tracking while significantly reducing energy consumption compared to continuous monitoring, as the system remains in low-power states between scanning cycles.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances inventory management accuracy, reduces human error, streamlines billing processes, and ensures timely restocking and product recall, while providing real-time location tracking and automated invoicing.
Implementation Method 1
Each implant and instrument box is tagged with a unique RFID tag as well as a QR code. The RFID tag and QR code identify the implant and/or instrument (lot number, part number, expiration date, etc.).
Implementation Method 2
a mobile website/app is included that scans the QR code printed on the implant and instrument boxes
Implementation Method 3
The transportation and storage device can be shipped to a hospital or surgery center and stored there. The RFID scanner scans the contents of the transportation and storage device periodically, when the device is opened and closed, and on a pre-determined schedule.
