Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed configuration settings are used for all NFC reader devices, then device complexity is reduced, but communication reliability deteriorates due to failed communication cycles with different reader types
Solution Approach 1:
The patent implements dynamic configuration settings that automatically adapt to different NFC reader device types. The system classifies the reader device and adjusts modem, equalizer, and decoder settings in real-time based on the classification, transforming static configuration into dynamic adaptation to resolve the contradiction between reliability and complexity
Solution Approach 2:
The patent changes multiple configuration parameters (modem settings, equalizer initialization settings, decoder settings) based on the classified reader device type. This parameter adaptation allows the communication device to optimize its performance for different reader devices, improving communication reliability without requiring manual configuration
2Reliability
If configuration settings are adjusted for each reader device type, then communication reliability improves, but processing time increases during the initial communication phase
Solution Approach 1:
The patent performs classification and configuration adjustment during the initial communication phase, specifically during the reception of the preamble and synchronization code or first command message. By completing the configuration adaptation before main data transmission begins, the system minimizes time loss while ensuring reliable communication for the subsequent data exchange
