Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional biometric systems are used for user verification, then security can be maintained, but user convenience deteriorates due to cumbersome devices and procedures
Solution Approach 1:
The patent combines multiple biometric verification functions (iris scanning, fingerprint sensing, facial recognition) into a single contact lens device. The contact lens integrates light sensors, readout circuitry, and processing capabilities within the lens structure itself, eliminating the need for separate verification devices and improving user convenience while maintaining security.
Solution Approach 2:
The contact lens is designed to perform multiple biometric verification functions simultaneously - iris pattern detection through light sensors, fingerprint analysis through integrated sensors, and facial recognition capabilities. This multi-functional approach consolidates what would traditionally require multiple separate devices into one universal verification system.
2Reliability
If multiple secure devices are deployed, then security coverage is improved, but user convenience deteriorates due to the increasing number of verification devices
Solution Approach 1:
The contact lens serves as a universal biometric verification device that can authenticate across multiple secure systems and devices. By integrating multiple biometric modalities (iris, fingerprint, facial recognition) into a single lens, the system maintains broad security coverage while requiring only one device for verification across all secure access points.
Solution Approach 2:
The contact lens contains integrated power sources (such as miniaturized batteries or energy harvesting components) and self-contained processing capabilities, allowing it to function autonomously without requiring connection to external power sources or processing units at each secure device. This enables the lens to provide security verification across multiple devices independently.
