Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple authentication methods (motion sensors, biometric sensors, ECG, PPG) are integrated to enhance security and accuracy, then authentication reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple authentication methods (motion sensors, biometric sensors, ECG, PPG) into a single integrated authentication system. The processor synthesizes data from all these sensors to perform comprehensive user authentication, merging previously separate authentication functions into one unified system that improves reliability while managing complexity through integration.
Solution Approach 2:
The authentication apparatus is designed to perform multiple authentication functions simultaneously - motion-based signature recognition, biometric verification, ECG analysis, and PPG measurement. This multi-functional design allows a single device to provide comprehensive security through diverse authentication methods, enhancing reliability without requiring separate dedicated devices for each method.
2Measurement precision
If comprehensive authentication data collection is performed to improve security, then authentication accuracy is improved, but processing time increases
Solution Approach 1:
The system performs preliminary authentication assessments by analyzing motion data and biometric signals as they are collected during natural user interactions. Rather than waiting for complete data collection from all sensors, the processor begins evaluating authentication criteria incrementally, allowing faster initial assessments while maintaining comprehensive accuracy checks.
Solution Approach 2:
The authentication process operates continuously by processing data streams from motion sensors, biometric sensors, ECG, and PPG in real-time as the user interacts with the device. This continuous processing enables the system to maintain high authentication accuracy through comprehensive data analysis while minimizing delays by not requiring discrete batch processing of all sensor data.
