Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional fingerprint authentication devices are used, then authentication accuracy is improved, but device cost and complexity increase
Solution Approach 1:
The touch screen serves dual functions: as a user interface for interaction and as a biometric sensor for fingerprint authentication. By integrating fingerprint sensing capability into the existing touch screen, the system eliminates the need for separate dedicated fingerprint sensors, thereby reducing device complexity and cost while maintaining authentication accuracy through software-based fingerprint analysis of touch patterns.
2Productivity
If dedicated fingerprint sensors are used, then authentication speed is improved, but device cost increases
Solution Approach 1:
The existing touch screen infrastructure is leveraged to perform fingerprint authentication functions. The touch screen's inherent capacitive sensing capability is utilized to detect fingerprint patterns without requiring additional dedicated hardware components. This self-service approach allows the touch screen to serve its primary function while simultaneously enabling biometric authentication, thereby reducing device cost while maintaining authentication speed through efficient software processing.
3Measurement precision
If multiple data samples are captured and aggregated, then authentication accuracy is improved, but processing time increases
Solution Approach 1:
The system captures multiple fingerprint data samples continuously as the user interacts with the touch screen interface. Rather than requiring separate authentication actions, each touch interaction generates additional fingerprint samples that are aggregated in real-time. This continuous sampling approach improves authentication accuracy through data aggregation while minimizing processing time by utilizing ongoing user interactions rather than requiring dedicated authentication steps.
