Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the label issuing apparatus temporarily stops the conveyance of the label to write data in the RFID tag, then the data writing reliability is improved, but the processing time increases significantly
Solution Approach 1:
The patent implements continuous conveyance of labels through the processing apparatus while the RFID tag data is being written. The label moves continuously through the reader/writer zone without stopping, eliminating idle time between writing operations and maintaining constant productivity.
Solution Approach 2:
The patent employs a movable antenna system that dynamically adjusts its position to track and maintain optimal communication distance with the RFID tag on the moving label. This dynamic positioning enables reliable data writing during continuous label conveyance.
2Manufacturing precision
If the label issuing apparatus temporarily stops the conveyance of the label to write data in the RFID tag, then the data writing completeness is improved, but the productivity decreases
Solution Approach 1:
The system maintains uninterrupted label flow through the processing line while completing full RFID tag data writing operations. Multiple antennas can operate in sequence or parallel to ensure complete data writing without interrupting the continuous label conveyance, maximizing throughput.
Solution Approach 2:
The system performs preliminary positioning and preparation of the antenna system before the label enters the writing zone, ensuring that data writing can commence immediately upon label arrival. This eliminates setup delays and maintains continuous high-speed processing.
3Productivity
If a movable antenna system is used to track the RFID tag during conveyance, then continuous communication is enabled, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical antenna positioning systems with electronic beam steering or phased array technology. This allows the antenna to electronically track and communicate with moving RFID tags without physical movement, dramatically reducing mechanical complexity while maintaining continuous communication capability.
Solution Approach 2:
The antenna system is designed to perform multiple functions: tracking, communication, and data writing, all within a single integrated unit. This multi-functionality reduces the number of separate components needed and simplifies the overall system architecture.
