Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a millimeter-wave biometric detector is incorporated to enable user authentication, then security and user experience are improved, but device complexity increases
Solution Approach 1:
The patent combines the millimeter-wave biometric detector, control circuitry, and aerosol provision functions into a single integrated device. The biometric detector and control circuitry are merged with the aerosol generation system, allowing authentication and aerosol delivery to occur within one unified device structure, thereby managing complexity through integration rather than separate components.
Solution Approach 2:
The millimeter-wave biometric detector serves multiple functions: it detects facial features for authentication, identifies authorized users, and triggers aerosol generation. This multi-functionality reduces the need for separate authentication devices and simplifies the overall system architecture while improving security and user experience.
2Reliability
If biometric detection is used to control activation state, then unauthorized access is prevented, but ease of operation is reduced
Solution Approach 1:
The system performs biometric authentication automatically in advance before allowing device activation. The millimeter-wave detector continuously monitors for authorized users, and the control circuitry pre-approves activation based on detected biometric data, eliminating the need for manual authentication steps during operation.
Solution Approach 2:
The device performs self-authentication by automatically detecting and verifying user biometric features without requiring manual intervention. The system independently controls its own activation state based on biometric detection results, freeing the user from complex authorization procedures while maintaining security.
3Measurement precision
If millimeter-wave emission and detection is used for high definition scanning, then measurement precision is improved, but use of energy increases
Solution Approach 1:
The millimeter-wave emitter operates in periodic pulses rather than continuous emission, scanning facial features at specific intervals sufficient for authentication. This pulsed operation maintains high measurement precision for biometric verification while significantly reducing overall energy consumption compared to continuous operation.
