Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional digital key pairing process is used, then the pairing can be completed, but the process is cumbersome and lacks safety features
Solution Approach 1:
The system performs preliminary actions by detecting NFC tagging and audio device pairing status before initiating the digital key pairing process. This ensures that the mobile device is properly positioned and connected before proceeding, making the process more reliable without adding user burden
Solution Approach 2:
The system implements feedback mechanisms by displaying user interface requests for confirmation and requiring explicit user approval before completing digital key registration. This feedback loop ensures user awareness and control, enhancing safety while maintaining ease of operation
2Reliability
If multiple detection steps are added to enhance security, then pairing safety is improved, but the process complexity increases
Solution Approach 1:
The system merges multiple detection functions into a unified pairing process. The NFC tagging detection module and audio device pairing detection module work together seamlessly to initiate the digital key process, reducing perceived complexity while maintaining security
Solution Approach 2:
The system performs self-service by automatically detecting NFC tagging and audio device pairing status without requiring manual user input. This automation reduces process complexity from the user perspective while implementing multiple security checks
