Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single biometric recognition method is used, then the device complexity is low, but the authentication success rate decreases due to adverse effects on the sensor
Solution Approach 1:
The electronic device incorporates multiple biometric recognition sensors (fingerprint sensor, iris sensor, face recognition sensor) that can perform different authentication methods. The processor selectively activates appropriate sensors based on context information such as ambient light conditions, ensuring high authentication success rates across varying environments without requiring all sensors to be constantly active, thus balancing reliability with device complexity.
2Reliability
If multiple biometric sensors are equipped, then the authentication success rate improves, but the device complexity increases
Solution Approach 1:
The system dynamically selects which biometric sensor to activate based on real-time context information. The processor evaluates ambient light conditions and other environmental factors, then selectively activates the most appropriate sensor (e.g., using fingerprint sensor in low light, face recognition in bright light). This dynamic adaptation maintains high authentication success rates while avoiding the constant operational overhead of all sensors, effectively managing device complexity.
Solution Approach 2:
The system changes operational parameters by adjusting which sensor is active based on context. Instead of maintaining all sensors at constant readiness, the processor modifies the operational state of sensors according to environmental parameters such as ambient light intensity. This parameter-based selection optimizes authentication success while reducing the effective complexity by keeping only necessary sensors active.
3Measurement precision
If context information is obtained and processed, then the authentication method selection accuracy improves, but the processing time increases
Solution Approach 1:
The system performs preliminary evaluation of context information (such as ambient light conditions) before initiating the authentication process. By assessing environmental factors in advance, the processor can pre-determine the most suitable biometric sensor to use, avoiding time-consuming trial-and-error attempts during the actual authentication. This preliminary action ensures accurate method selection while minimizing processing time during the critical authentication moment.
