Solution Overview
Problem
Existing RFID media processing systems face challenges in promptly and securely verifying the normal execution of reading and writing operations, especially at high speeds, and in minimizing errors during data processing.
Innovation Solution
A reading and writing verification device with multiple device antennas along a transfer path, including a first antenna for reading unique identification numbers, a second and third antenna for writing data, and a fourth antenna for verifying written data, along with a die cutting unit for error handling, allows for rapid and secure processing of RFID media.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple device antennas are provided sequentially on the transfer path to enable high-speed processing of multiple RFID media, then productivity is improved, but device complexity increases
Solution Approach 1:
The verification function is segmented into two distinct device antennas: a third device antenna for writing medium data and a fourth device antenna for verifying the written data. This segmentation allows each antenna to perform its specific function independently, enabling high-speed processing while maintaining verification capability without requiring a single complex antenna to perform multiple functions simultaneously.
2Reliability
If a fourth device antenna is added specifically for verification purposes, then reliability is improved, but device complexity increases
Solution Approach 1:
The fourth device antenna acts as an intermediary verification component that independently checks the data written by the third device antenna. This intermediary verification mechanism ensures data integrity and operational reliability without requiring the writing antenna itself to perform verification, thereby separating concerns and improving reliability through dedicated verification functionality.
3Loss of time
If multiple device antennas are provided to enable prompt verification of reading and writing operations, then response time is improved, but device complexity increases
Solution Approach 1:
The fourth device antenna is positioned sequentially after the third device antenna on the transfer path, performing verification as a preliminary action before the RFID medium exits the system. This preliminary verification ensures that any errors in reading or writing operations are detected immediately, reducing the time lost to undetected errors while maintaining a streamlined sequential process that doesn't require complex parallel processing.
