Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a biometric input device is integrated into a keyboard key, then security is improved, but device complexity increases
Solution Approach 1:
The patent combines a fingerprint sensor with a keyboard key into a single integrated component. The fingerprint sensor is positioned within the key structure, allowing the key to serve dual purposes: as a mechanical input device and as a biometric authentication sensor. This merging eliminates the need for separate biometric devices while enhancing security functionality.
2Reliability
If a fingerprint sensor is integrated into a key, then security is improved, but manufacturing complexity increases
Solution Approach 1:
The keyboard key is designed to perform multiple functions: mechanical pressing for standard keyboard input and fingerprint capture for biometric authentication. The key structure incorporates a fingerprint sensor that can be activated when the key is pressed, allowing a single component to serve both conventional typing and security verification purposes, thereby simplifying the overall device architecture.
3Length of moving object
If mobile devices are made smaller for portability, then portability is improved, but space for biometric features is reduced
Solution Approach 1:
The patent integrates a fingerprint sensor within the existing keyboard key structure, eliminating the need for separate biometric authentication hardware. By utilizing the space already allocated for keyboard keys, the design accommodates biometric functionality without increasing overall device size, thus maintaining portability while enhancing security capabilities.
