Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing biometric card personalization devices are used, then biometric data can be captured and stored, but the devices are costly, complex, and environmentally unfriendly
Solution Approach 1:
The patent extracts the essential functional components (antennas) from the complex existing personalization devices and integrates them directly into the support sheet itself. This eliminates the need for separate, complex electronic devices while maintaining the core functionality of powering the card and capturing biometric data through the fingerprint sensor.
Solution Approach 2:
The support sheet becomes self-sufficient by having antennas directly integrated into its structure. The sheet itself provides the electromagnetic coupling capability without requiring external power sources or complex electronics, allowing it to power the integrated circuit card and enable biometric capture autonomously.
2Reliability
If existing biometric card personalization devices are used, then biometric data can be captured and stored, but additional power sources and complex electronics are required
Solution Approach 1:
The patent removes the need for separate power sources by integrating antennas directly into the support sheet. The electromagnetic energy is provided through the sheet itself, eliminating batteries or external power supplies that would add complexity and cost.
Solution Approach 2:
The support sheet performs multiple functions simultaneously: it provides structural support, integrates electromagnetic antennas for powering the card, and enables biometric data capture. This multi-functionality eliminates the need for separate power sources and electronic components.
3Reliability
If traditional personalization devices are used, then biometric data can be stored, but the devices are unintuitive and have limited display capabilities
Solution Approach 1:
The patent merges the personalization functionality directly into the support sheet itself. The sheet becomes both the carrier and the functional device, eliminating the need for separate, complex personalization equipment with limited displays and unintuitive interfaces.
Solution Approach 2:
The support sheet provides all necessary functions (powering, data capture, storage) through its integrated structure, making the personalization process intuitive and user-friendly without requiring complex external devices or specialized操作 procedures.
