Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fingerprint identification is used for unlocking only, then security is provided, but convenience and quickness for accessing applications are insufficient
Solution Approach 1:
The system pre-registers multiple fingerprint templates and associates each with specific applications or functions before actual use. When a user needs to access an application, the corresponding fingerprint has already been prepared and linked in the database, enabling immediate execution without manual navigation or delays
Solution Approach 2:
The fingerprint identification system is extended from a single unlocking function to multiple functions including application launching, function execution, and mode switching. Each fingerprint template can be associated with different applications, making the single biometric sensor serve multiple purposes and greatly improving access convenience
2Adaptability or versatility
If multiple fingerprint templates are registered for different functions, then convenience and functionality are improved, but system complexity increases
Solution Approach 1:
The system automatically manages multiple fingerprint templates and their associated applications without requiring user intervention for complex configurations. The control unit automatically identifies which fingerprint was scanned, retrieves the corresponding template from the database, determines the holding manner via sensors, and executes the appropriate application or function, making the complexity invisible to the user
Solution Approach 2:
A control unit is introduced as an intermediary between the fingerprint sensor and the various applications. This control unit manages the fingerprint database, performs template matching, detects holding manner through acceleration/gravity sensors, and routes to appropriate applications, thereby organizing the system complexity in a centralized and manageable way
3Speed
If fingerprint identification is performed in screen off state for quick access, then responsiveness is improved, but privacy protection is compromised
Solution Approach 1:
Different privacy levels are assigned to different applications and functions based on their sensitivity. The system can configure which applications can be launched from screen-off state and which require screen-on state, allowing users to balance convenience and privacy on a per-application basis. Sensitive applications maintain security while less sensitive ones provide quick access
4Measurement precision
If holding manner detection is added to determine operation type, then precision of operation control is improved, but device complexity increases
Solution Approach 1:
The acceleration sensor and gravity sensor, which are standard components in mobile terminals for other purposes (screen orientation, step counting, etc.), are repurposed to detect holding manner for fingerprint operations. This approach avoids adding dedicated sensors while enabling precise detection of whether the device is held horizontally or vertically, thereby controlling complexity

Implementation Method 2
Whether the holding manner of the mobile terminal is a lateral holding manner or a lengthways holding manner is determined according to information detected by an acceleration sensor or a gravity sensor of the mobile terminal
