Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fingerprint recognition sensor is integrated into the display, then device complexity is reduced and user interface is simplified, but the ability to control display operations and select objects based on fingerprint detection is limited
Solution Approach 1:
The fingerprint recognition sensor is integrated into the display structure, allowing the display to serve dual purposes: visual output and biometric authentication. This multi-functional integration reduces device complexity while enabling versatile control operations including object selection, rotation detection, and directional input based on fingerprint patterns
2Reliability
If fingerprint detection is used for security authentication, then security features are enhanced, but the method of utilizing detected fingerprints for controlling display operations is inefficient
Solution Approach 1:
The system performs preliminary analysis of fingerprint patterns immediately upon detection, extracting rotational and directional information in real-time. This preliminary processing enables immediate control of display operations and object selection without requiring separate authentication steps, thereby enhancing both security and processing efficiency
Solution Approach 2:
The system provides immediate feedback by utilizing the detected fingerprint pattern to directly control display operations and object selection. The fingerprint detection result feeds back into the user interface, enabling dynamic object selection, rotation control, and directional navigation based on the authenticated fingerprint characteristics
3Ease of operation
If fingerprint recognition sensor recognizes fingerprints through the display, then user interaction is simplified, but the precision of object selection and display control based on fingerprint characteristics is limited
Solution Approach 1:
The system analyzes specific local characteristics of the fingerprint pattern, such as ridge orientation, rotation angle, and directional vectors at different positions within the fingerprint. By extracting these localized features, the system achieves precise object selection and display control while maintaining simplified user interaction through the integrated display sensor
