Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an electronic device lacks NFC capabilities, then device complexity is reduced, but secure data transmission capability deteriorates
Solution Approach 1:
The patent introduces a secondary computing device as an intermediary that bridges the gap between electronic devices lacking NFC capabilities and the secure data transmission requirement. The secondary device receives user information from the first device via wireless connection, processes it through its secure data exchange module with NFC capability, and transmits it to the service provider. This mediator approach allows devices with limited capabilities to access secure transmission functions without requiring all devices to possess the full capability set.
2Reliability
If secure data exchange module is added to electronic device, then secure data transmission capability is improved, but device complexity increases
Solution Approach 1:
The secondary computing device is designed with multi-functionality to serve multiple purposes: it acts as a secure data exchange module for NFC transactions, provides a user interface for conducting secure transmissions, and communicates with both the first electronic device and service providers via wireless connections. By consolidating these diverse functions into a single secondary device, the system avoids the need for each electronic device to incorporate separate secure transmission hardware, thereby managing complexity while maintaining capability.
3Reliability
If user information is transmitted via secondary device, then security is improved through proximity-based protocols, but transmission distance is limited
Solution Approach 1:
The transmission process is segmented into distinct phases: (1) The first electronic device transmits user information to the secondary device via wireless connection (Bluetooth/Wi-Fi), (2) The secondary device's secure data exchange module processes the information using NFC proximity protocol, and (3) The secondary device transmits the processed information to the service provider. This segmentation allows the system to leverage the security benefits of proximity-based NFC for the critical data exchange step while using longer-range wireless protocols for the initial and final transmissions, effectively resolving the contradiction between security and transmission distance.
