Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physiological state feature information is collected using a first sensing apparatus on the mobile terminal device, then convenience of unlocking is improved, but device complexity increases
Solution Approach 1:
The first sensing apparatus is integrated into the mobile terminal device to perform multiple functions: it collects physiological state feature information for unlocking authentication, monitors user health data, and enables contactless interaction. This multi-functionality reduces the need for separate external devices while improving unlocking convenience.
Solution Approach 2:
The mobile terminal device uses its own built-in first sensing apparatus to collect and process physiological state feature information for authentication. The system serves itself by eliminating dependence on external wearable devices or additional authentication equipment, thereby improving convenience while managing device complexity through self-contained functionality.
2Reliability
If physiological state feature information is used for authentication, then security is enhanced, but measurement precision requirements increase
Solution Approach 1:
The system measures multiple physiological parameters (heart rate, blood pressure, body impedance, oxygen saturation) simultaneously and compares them against pre-stored reference values. By changing from single-parameter to multi-parameter authentication, the system enhances security while distributing the precision requirement across multiple measurements rather than demanding extreme precision from a single measurement.
Solution Approach 2:
The authentication system uses a composite approach by combining multiple physiological state features (heart rate, blood pressure, impedance, oxygen saturation) into a comprehensive authentication profile. This composite authentication method enhances security by requiring multiple characteristics to match, reducing the burden on any single measurement's precision.
3Reliability
If a wearable mobile device with second sensing apparatus is used to transmit unlocking information, then security is enhanced, but device complexity increases
Solution Approach 1:
The system merges the authentication functionality into a single integrated workflow: the wearable device's second sensing apparatus collects physiological information, transmits it wirelessly to the mobile terminal, which then uses its first sensing apparatus to verify against stored data. This combination of devices creates a layered security system while distributing complexity across separate components rather than concentrating it in one device.
