Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate RFID devices are used to read different frequency tags, then reading capability across various frequencies is achieved, but device quantity and operational complexity increase
Solution Approach 1:
The patent combines multiple RFID reading capabilities (LF, HF, UHF frequencies) into a single handheld device. The device includes multiple antennas and circuitry configured to operate across different frequency ranges, eliminating the need to carry multiple separate RFID readers for different frequency tags.
Solution Approach 2:
The handheld device is designed with universal functionality to read and emulate RFID tags across multiple frequency ranges (low frequency, high frequency, and ultra-high frequency). The device can adapt its operating frequency and protocol based on the target tag type, making it a multi-functional tool for diverse RFID applications.
2Measurement precision
If multiple specialized RFID devices are used for different protocols, then protocol-specific reading accuracy is maintained, but ease of operation decreases
Solution Approach 1:
The device incorporates dynamic frequency selection and protocol adaptation capabilities. The control circuitry automatically detects the tag type and adjusts operating parameters (frequency, modulation scheme, protocol) in real-time, allowing the device to maintain high reading accuracy across different protocols without requiring manual configuration by the user.
Solution Approach 2:
The device can change its operating parameters (frequency, power level, communication protocol) based on the detected tag type. This parameter adaptation allows the device to optimize its reading accuracy for each specific protocol while maintaining a single unified interface for the user.
3Weight of moving object
If a single device handles multiple frequencies, then device portability is improved, but device complexity increases
Solution Approach 1:
The device internally segments different frequency handling functions into separate modular components (LF antenna/circuitry, HF antenna/circuitry, UHF antenna/circuitry). Each module is independently designed for its specific frequency range, but they are integrated into a single handheld unit with a unified control system that manages which module is active based on the target tag type.
