Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RFID tags are attached to individual bulk cases containing electronic components, then tracking accuracy for each case is improved, but management complexity increases when handling large numbers of cases
Solution Approach 1:
The patent implements a hierarchical RFID tagging system where individual bulk cases contain RFID tags, and outer cases containing multiple bulk cases also contain RFID tags. This nested structure allows tracking at different levels of aggregation, enabling efficient management of large numbers of cases by reading tags at the outer case level rather than individually at each bulk case level.
2Productivity
If multiple RFID tags are used in a hierarchical structure, then communication efficiency is improved through selective reading, but system complexity increases
Solution Approach 1:
The RFID tagging system is segmented into multiple hierarchical levels (individual bulk cases and outer cases), allowing the system to divide tracking operations into manageable segments. This enables selective reading of RFID tags based on the specific management need, improving communication efficiency by avoiding the need to read every individual tag in large quantities.
Solution Approach 2:
The hierarchical RFID system provides multi-functionality by enabling both individual case tracking and bulk case tracking through a unified tag structure. The same RFID infrastructure supports multiple levels of aggregation, allowing the system to adapt to different management scenarios without requiring separate tracking systems.
3Measurement precision
If individual bulk cases are managed separately, then tracking precision for each case is maintained, but time consumption increases for managing large quantities
Solution Approach 1:
By nesting bulk cases within outer cases and placing RFID tags at both levels, the system enables bulk reading of multiple individual case tags through the outer case tag. This maintains tracking precision for each individual case while dramatically reducing the time required to manage large quantities of cases, as operators can read multiple tags simultaneously at the outer case level.
