Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If NFC card activation is based on geo-fence information, then the activation can be triggered in specific geographic areas, but the application range is limited particularly in locations with weak or unavailable positioning signals
Solution Approach 1:
The patent introduces Bluetooth signal as an intermediary mechanism to trigger NFC card activation. Instead of relying solely on geo-fence positioning, the system uses Bluetooth connection events between the electronic device and target devices as a mediator to initiate NFC activation, thereby expanding functionality to areas where positioning signals are unavailable.
Solution Approach 2:
The patent makes the NFC activation system multi-functional by supporting multiple trigger mechanisms: both traditional geo-fence-based activation and the new Bluetooth-based activation. This allows the system to adapt to different scenarios and environments, whether positioning signals are available or not, thus achieving universality across diverse application contexts.
2Adaptability or versatility
If NFC card activation relies on positioning information, then geographic-based activation can be achieved, but the method is susceptible to environmental factors and has limited applicability
Solution Approach 1:
Bluetooth signal serves as an intermediary that is less susceptible to environmental factors compared to positioning signals. The system uses Bluetooth connection events as a more reliable trigger mechanism in various environments, including underground locations where positioning signals fail, thereby reducing environmental susceptibility.
Solution Approach 2:
The patent changes the triggering parameter from geo-fence coordinates to Bluetooth signal characteristics (connection events). This parameter change makes the activation mechanism more robust against environmental variations, as Bluetooth signals maintain better stability and availability across different physical environments compared to satellite positioning signals.

AI summary
This application provides an NFC card activation method and apparatus, applied to a first electronic device, where a Bluetooth function is enabled in the first electronic device, and the method comprises: detecting that a Bluetooth connection event occurs between Bluetooth identifiers of a second electronic device and the first electronic device; selecting a target Bluetooth identifier from the Bluetooth identifiers based on Bluetooth signal strength of the second electronic device; and activating NFC cards corresponding to the target Bluetooth identifier. Compared with geo-fence information, Bluetooth of a device is unique, so that a requirement of using the Bluetooth in multiple different places can be met. In addition, compared with positioning information, a Bluetooth signal is less susceptible to an environment. Therefore, the manner of activating an NFC card based on the Bluetooth connection has a wider application range.
