Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If optical check for match between personal data and person features is used, then identification can be performed, but the system is vulnerable to forgery and manipulation

Engineering Contradiction:

Improveidentification reliabilityVSAvoidforgery vulnerability

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent combines multiple security elements (biometric features, electronic keys, cryptographic algorithms) into a composite identification system. The biometric template is encrypted with a key derived from the biometric data itself, creating a layered security structure that resists both forgery and brute-force attacks.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The system transforms biometric data into a different parameter space through encryption. The original biometric template is converted into an encrypted form stored in the identification means, while the decryption key is stored separately in the authentication device, changing the security parameters from simple data storage to cryptographic protection.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If automated reading and processing of identification means is implemented, then processing speed increases, but objective verification becomes more difficult

Engineering Contradiction:

Improveprocessing speedVSAvoidverification accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The patent replaces subjective human visual verification with automated cryptographic verification. Instead of a person visually comparing features, the system uses cryptographic algorithms to objectively verify the match between the presented biometric data and the stored template, providing both speed and objective accuracy.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If electronic key is stored in memory means linked to person-related feature, then security against manipulation improves, but device complexity increases

Engineering Contradiction:

Improveanti-manipulation securityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the biometric verification function with cryptographic key storage. The electronic key is not stored separately but is derived from and linked to the biometric template itself through cryptographic processing. This integration reduces the need for separate key management systems while enhancing security.

Inventive Principle:

Principle #5Merging (Combining)
