Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple biometric features are used together for multimodal biometric recognition, then recognition accuracy is improved, but device complexity and cost increase due to requiring different acquisition devices for each biometric feature
Solution Approach 1:
The patent combines multiple biometric recognition functions (foot type recognition, dermatoglyph recognition, and pressure distribution recognition) into a single integrated device. The display panel serves as both the display interface and the sensing surface, with photosensitive units detecting light shielding from foot dermatoglyphs while pressure sensing units simultaneously detect pressure distribution. This merging of multiple recognition functions into one device resolves the technical contradiction by maintaining high recognition accuracy through multimodal biometrics while reducing device complexity compared to using separate devices for each biometric feature
Solution Approach 2:
The display panel is designed to perform multiple functions: it displays information to users, serves as the acquisition surface for foot type and dermatoglyph recognition through its photosensitive units, and acts as the sensing surface for pressure distribution detection through integrated pressure sensing units. This multi-functionality allows a single device to replace multiple specialized devices, resolving the contradiction between recognition accuracy and device complexity
2Reliability
If multiple acquisition devices are used for different biometric features, then recognition accuracy is improved, but sampling time increases
Solution Approach 1:
The patent merges foot type recognition, dermatoglyph recognition, and pressure distribution recognition into simultaneous operations within a single device. When a user places their foot on the display panel, all three types of biometric data are captured at the same time through different sensing mechanisms integrated in the panel, eliminating the sequential sampling time required by multiple separate devices while maintaining high recognition accuracy through the combination of multiple biometric features
3Reliability
If multiple acquisition devices are used for different biometric features, then recognition accuracy is improved, but application cost increases
Solution Approach 1:
The patent combines multiple biometric recognition functions into a single device, reducing the total number of acquisition devices needed. By integrating foot type recognition, dermatoglyph recognition, and pressure distribution recognition into one system with shared components (display panel, processing unit, storage), the patent reduces manufacturing costs and application expenses compared to deploying multiple separate devices, while maintaining high recognition accuracy through multimodal biometric data fusion
Solution Approach 2:
The display panel is designed as a universal component that performs display, light shielding detection for dermatoglyph recognition, and pressure sensing functions. This multi-functionality reduces the need for multiple specialized devices, thereby lowering overall system cost while maintaining high recognition accuracy through the integration of multiple biometric recognition capabilities
