Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pharmacy kit management is time-consuming and error-prone due to manual recording and inspection of item information, particularly expiration dates, leading to inefficiencies and increased costs.
Innovation Solution
A system utilizing RFID technology to read and manage pharmacy kits, including RFID tags on items and kits, an information processing system, and electronic templates for automated verification and updating of kit contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual recording of item information is used, then flexibility in recording is maintained, but time consumption and error rates increase significantly
Solution Approach 1:
The patent replaces manual mechanical recording processes with an automated RFID system. RFID readers automatically detect and record item information (NDC, lot number, expiration date) when items are placed in or removed from kits, eliminating the need for manual data entry while maintaining operational flexibility.
Solution Approach 2:
The system enables self-service recording where the RFID tags on items automatically transmit their information to the RFID reader without human intervention. The kit management system automatically updates records based on RFID detections, allowing the system to service itself rather than requiring manual operations.
2Measurement precision
If manual inspection of kits is performed, then detailed verification is possible, but time consumption and error rates increase
Solution Approach 1:
The patent replaces manual visual inspection with automated RFID detection. The RFID reader automatically scans all items in a kit, reads their RFID tags containing verification information (NDC, lot number, expiration date), and compares them against required specifications, providing both accuracy and speed.
Solution Approach 2:
The system enables continuous verification by automatically detecting and validating all items in a kit during the kit assembly or inspection process. Rather than periodic manual checks, the RFID system provides continuous automated verification as items are handled, reducing both time and human error.
3Reliability
If highly trained pharmacy staff perform manual procedures, then accuracy is maintained, but operational efficiency decreases
Solution Approach 1:
The patent replaces skilled manual operations with automated RFID technology. The system automatically reads, verifies, and records item information without requiring trained pharmacy staff intervention, thereby eliminating the trade-off between human expertise and operational efficiency while maintaining high accuracy through automated validation.
Solution Approach 2:
The RFID system performs self-service verification and recording functions that previously required trained staff. The automated system independently reads item information, validates against templates, and updates records without human intervention, significantly improving productivity while maintaining reliability through systematic automated control.
4Device complexity
If manual recording procedures are used, then system simplicity is maintained, but cost and error rates increase
Solution Approach 1:
The patent replaces simple manual recording with automated RFID technology. While the technology itself adds some complexity, the system simplicity is maintained at the operational level because the RFID readers and tags automatically handle all recording functions without requiring complex manual procedures, thereby reducing error rates.
Solution Approach 2:
The system uses RFID tags as digital copies of item information (NDC, lot number, expiration date) that automatically transmit data to the RFID reader. This copying mechanism eliminates manual transcription errors while maintaining operational simplicity, as the data is automatically read and recorded without human intervention.
