Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensors (biometric sensor, fingerprint sensor, touchscreen sensor) are integrated into the mobile device, then authentication security is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple authentication sensors (biometric sensor, fingerprint sensor, touchscreen sensor) into a single mobile device, integrating their functions to work together for multi-factor authentication. This merging approach enables the device to simultaneously process multiple types of biometric data and authentication inputs, thereby improving overall authentication security while managing the complexity through unified device architecture.
Solution Approach 2:
The mobile device is designed with universal multi-functionality, where a single device platform supports multiple sensor types and authentication methods. The device can adaptively select and combine different authentication factors (biometric, fingerprint, touchscreen input) based on security requirements, making the system versatile and capable of handling various authentication scenarios without requiring separate dedicated devices for each sensor type.
2Reliability
If multiple sensors are integrated into the mobile device, then authentication security is improved, but the available space in the device is reduced
Solution Approach 1:
The patent merges multiple sensor functions into an integrated sensor array within the mobile device. By combining the biometric sensor, fingerprint sensor, and touchscreen sensor into a unified authentication system, the design optimizes space utilization. The sensors share common processing infrastructure and control circuits, reducing the total space required compared to implementing each sensor as a separate, standalone component.
Solution Approach 2:
The authentication sensors are arranged in a nested or layered configuration where the touchscreen sensor serves as the outer layer, the fingerprint sensor is positioned beneath it, and the biometric sensor is integrated at deeper layers. This nesting approach allows multiple sensing functions to occupy overlapping or adjacent spatial regions, maximizing the use of available device space while maintaining the functionality of each sensor.
3Object-affected harmful factors
If multiple sensors are used for authentication, then spoofing resistance is improved, but the difficulty of integrating and coordinating these sensors increases
Solution Approach 1:
The patent implements feedback mechanisms where the controller receives data from multiple sensors (touchscreen sensor, fingerprint sensor, biometric sensor) and processes them in sequence or combination. The system uses feedback from each sensor to determine the next authentication step, allowing dynamic coordination of sensor activation and data processing. This feedback-based approach simplifies the coordination complexity by providing a structured decision-making process that adapts to the authentication state.
Solution Approach 2:
The system performs preliminary actions by pre-configuring the sensor coordination logic and authentication protocols before actual authentication occurs. The controller is pre-programmed with the sequence and methods for coordinating different sensors, and the system establishes communication protocols and data processing pipelines in advance. This preliminary setup reduces the real-time coordination complexity during actual authentication operations.
