Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the Windows operating system's proximity API is used for NFC communication, then the system maintains stability and compatibility, but application programs cannot access detailed NFC protocol information such as UID or card types
Solution Approach 1:
The system is divided into two operational modes: kernel mode for detecting readable elements and capturing raw NFC data, and user mode for analyzing the captured data. This segmentation allows the kernel mode to maintain system stability while the user mode provides enhanced data accessibility to application programs.
Solution Approach 2:
A capturing module is introduced as an intermediary component that bridges the kernel mode and user mode. This capturing module captures original NFC data from the kernel mode and outputs it to the user mode, enabling application programs to access detailed NFC protocol information without compromising system stability.
2Adaptability or versatility
If application programs need detailed NFC protocol information, then the flexibility and convenience of NFC applications are improved, but the existing proximity API restrictions prevent access to such information
Solution Approach 1:
The system architecture is segmented into distinct functional modules: an interface drive module in kernel mode for detection, a capturing module for data interception, and an analyzing module in user mode for processing. This modular segmentation enables enhanced NFC application flexibility while managing system complexity through clear functional separation.
Solution Approach 2:
The capturing module serves as an intermediary that enables data flow from the kernel mode to the user mode without requiring modifications to the existing proximity API. This intermediary approach provides the needed flexibility for NFC applications while maintaining compatibility with the existing system architecture.
3Ease of operation
If manual account information input is required for login, then the system maintains security control, but the login process becomes time-consuming and inconvenient
Solution Approach 1:
The system performs preliminary actions by capturing and storing NFC tag information and account information in advance. During the login process, the analyzing module automatically retrieves and processes this pre-captured data, eliminating the need for manual account information input and significantly reducing login time while maintaining security.
Solution Approach 2:
The system enables self-service login functionality where the NFC electronic device automatically captures, analyzes, and processes NFC tag information and account information without requiring manual user input. This self-service approach improves login convenience and reduces the time users spend on the authentication process.
