Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple RFID standards (EPC, ISO 18000) are supported, then compatibility and versatility are improved, but system complexity increases
Solution Approach 1:
The patent introduces a file system as an intermediary layer between the RFID reader hardware and the application software. This file system provides a standardized interface for accessing transponder data regardless of the underlying RFID standard, thereby maintaining compatibility across EPC, ISO 18000, and other standards while hiding the complexity of standard-specific protocols from the application layer.
Solution Approach 2:
The file system is designed with universal functionality to handle multiple RFID standards through a common interface. It implements standard file operations (open, read, write, close) that work uniformly across different transponder types and standards, allowing a single system to serve multiple purposes without requiring separate handling logic for each standard.
2Ease of operation
If RFID tags are represented as files in a file system, then ease of operation and integration with existing systems are improved, but data access overhead increases
Solution Approach 1:
The patent creates a virtual copy of the RFID transponder data in the file system, allowing applications to interact with tag information using familiar file operations. This copying approach enables seamless integration with existing file-based information systems while maintaining efficient data access through direct memory mapping and buffered I/O operations, minimizing the overhead introduced by the abstraction layer.
