Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple biometric sensors are integrated into a single device, then the functionality and versatility of the system is improved, but the device complexity and susceptibility to cross-contamination increase
Solution Approach 1:
The device is divided into separate isolation chambers, each housing a different biometric sensor type (e.g., fingerprint sensor, iris camera, facial recognition camera). These chambers are physically separated by walls or partitions that prevent cross-contamination while allowing each sensor to function independently. This segmentation resolves the contradiction by enabling multiple sensor types without proportionally increasing overall device complexity.
Solution Approach 2:
Multiple biometric sensors are nested within a compact housing structure where smaller sensor modules are positioned within or alongside larger ones. For example, an iris camera may be positioned above a fingerprint sensor, with shared structural elements and pathways. This nesting approach maximizes functionality within a constrained form factor while minimizing the increase in device complexity.
2Adaptability or versatility
If multiple biometric sensors are integrated into a single device, then the versatility of the system is improved, but the risk of cross-contamination between sensors increases
Solution Approach 1:
Physical isolation chambers with separate walls or partitions divide different biometric sensor pathways, preventing contaminants from transferring between sensors. Each chamber handles a specific biometric modality (e.g., contact-based fingerprint sensing in one chamber, non-contact iris scanning in another), eliminating cross-contamination risks while maintaining multi-sensor versatility.
Solution Approach 2:
Isolation barriers or filters act as intermediaries between different sensor chambers, allowing the system to maintain multiple sensor types without direct exposure between them. These intermediaries block potential contaminants while permitting the system to function as an integrated multi-biometric device.
3Productivity
If biometric data is stored locally in the device, then the processing speed and user experience are improved, but the security risk of data breaches increases
Solution Approach 1:
Biometric templates are pre-processed and stored in encrypted form in secure element hardware during device manufacturing or initial setup. This preliminary secure storage enables rapid authentication comparisons to be performed locally without repeatedly transmitting raw biometric data, achieving both fast processing and enhanced security through advance preparation of secure data formats.
Solution Approach 2:
Instead of storing permanent, sensitive biometric data, the system stores derived biometric templates that are mathematically one-way transformed from original biometric readings. These templates can be regenerated or replaced without affecting the original biometric characteristics, providing a disposable-like security model where compromised data can be discarded and regenerated.
