Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual pass code input is used for device connection, then security is maintained through verification, but the connection process becomes complex and time-consuming
Solution Approach 1:
The patent replaces the mechanical manual input system with a biometric authentication system. Instead of manually typing pass codes, the system uses fingerprint sensors or other biometric devices to automatically verify user identity, thereby maintaining security while eliminating the complexity of manual input operations
Solution Approach 2:
The system enables self-service authentication where the biometric device automatically performs verification without requiring user intervention for pass code entry. The electronic device autonomously completes the authentication process by comparing stored biometric data with the presented biometric information, simplifying the connection workflow
2Reliability
If manual pass code input is required for each connection, then authentication security is ensured, but the time required for connection increases
Solution Approach 1:
The system performs preliminary authentication by storing biometric information in advance. When connection is needed, the pre-stored biometric data is quickly compared with the presented biometric information, eliminating the time-consuming process of manual pass code entry while maintaining security verification
Solution Approach 2:
The patent substitutes the time-consuming manual typing process with rapid biometric verification. Fingerprint sensors or other biometric devices can verify identity in seconds compared to the time required for manual pass code input, significantly reducing connection time while preserving authentication security
3Ease of operation
If biometric authentication is implemented, then pairing process is simplified and security is enhanced, but the device requires additional biometric storage capabilities
Solution Approach 1:
The patent leverages the universal presence of biometric sensors in modern smartphones and electronic devices. By utilizing existing fingerprint sensors, face recognition cameras, or other biometric capabilities already built into devices, the system achieves simplified pairing without requiring entirely new hardware components
Solution Approach 2:
The system uses an intermediary biometric database that can be stored securely in the device's existing secure storage areas. This intermediary layer of biometric data enables authentication without requiring complex additional hardware, as the biometric templates can be stored in the device's existing secure memory regions
