Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the communication device stores multiple types of data (first data and second data) in the NFC interface simultaneously, then the device can communicate with various external devices, but the device complexity increases and operation becomes less efficient
Solution Approach 1:
The patent implements dynamic data storage by switching between storing first data and second data in the NFC interface based on the device's current state. The processor determines the device state and dynamically changes which data is stored, allowing the system to adapt its storage behavior rather than maintaining fixed simultaneous storage of all data types.
Solution Approach 2:
The patent prepares different data sets (first data and second data) in advance for different device states. Before communication occurs, the processor pre-determines which data should be stored based on the current state, ensuring the appropriate data is already in place when an external device initiates communication.
2Adaptability or versatility
If the communication device automatically switches between Initiator mode and Responder mode, then the device can operate in different power supply states, but the loss of time occurs due to mode switching overhead
Solution Approach 1:
The communication device autonomously monitors its own power supply state and automatically switches between Initiator and Responder modes without requiring external control or manual intervention. The processor continuously assesses the power supply condition and self-adjusts the operational mode accordingly.
Solution Approach 2:
The device implements periodic mode switching based on power supply conditions, alternating between Initiator mode and Responder mode at predetermined intervals or when power state changes occur. This periodic action allows the device to adapt to varying power availability while maintaining communication functionality.
3Productivity
If the NFC interface stores different data based on device state, then communication efficiency improves, but the difficulty of detecting and measuring the device state increases
Solution Approach 1:
The processor continuously monitors device state parameters (such as power supply status, communication history, or operational context) and uses this feedback information to determine which data should be stored in the NFC interface. The system creates a closed-loop control where state detection informs data storage decisions.
Solution Approach 2:
The patent changes the stored data parameters in the NFC interface based on detected device state changes. When the processor detects a change in device state (such as power supply status or communication mode), it相应地 changes which data set is stored, optimizing communication efficiency for the current state.

AI summary
A communication device may include an NFC interface, a processor, and a memory storing computer-readable instructions. The computer-readable instructions may instruct the communication device to store, in a case where a state of the communication device is a first state, first data in the NFC interface and to store, in a case where the state of the communication device is a second state, the second data in the NFC interface. The NFC interface may establish a first communication link between the communication device and a first external device and transmit the first data to the first external device via the first communication link. The NFC interface may establish a second communication link between the communication device and a second external device and transmit the second data to the second external device via the second communication link by using the NFC system.
