Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If physical identification documents are used for identity verification, then verification can be performed with simple equipment, but the process is time-consuming and prone to errors

Engineering Contradiction:

Improveverification equipment simplicityVSAvoidverification time

Core Design Contradiction:

Ease of manufactureVSLoss of time

Solution Approach 1:

The patent replaces manual physical document verification with automated digital credential verification using optical character recognition (OCR) technology and cryptographic validation. The system automatically extracts data from digital credentials, validates cryptographic signatures, and checks against databases, eliminating manual inspection and significantly reducing verification time while maintaining equipment simplicity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If self-issued digital credentials are used, then verification is faster and more convenient, but the assurance level is insufficient for high-security transactions

Engineering Contradiction:

Improveverification speedVSAvoididentity verification assurance

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent introduces an intermediary verification system that acts as a trusted third party between credential holders and verifying entities. This intermediary validates cryptographic signatures, verifies issuer authenticity, and cross-checks credential data against authoritative databases, thereby maintaining fast automated verification while significantly enhancing the assurance level through multiple validation layers.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary validation of digital credentials by pre-verifying cryptographic signatures, checking issuer credentials, and validating credential format against established standards before the actual verification transaction. This preliminary action ensures that only properly formed and authenticated credentials proceed to the verification stage, enhancing reliability without impacting transaction speed.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If multiple credential verification standards are supported, then interoperability is improved, but system complexity increases

Engineering Contradiction:

Improvecredential standard compatibilityVSAvoidverification system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal verification framework that can handle multiple credential standards (such as W3C Verifiable Credentials, ISO 18013-5, and other digital identity standards) through a single unified system. The framework includes standardized interfaces, common cryptographic validation mechanisms, and adaptable parsing logic that can process different credential formats without requiring separate verification systems for each standard, thereby achieving multi-functionality without proportionally increasing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of manufacture

If manual verification processes are used, then technical requirements are reduced, but human error increases and costs rise

Engineering Contradiction:

Improveverification system requirementsVSAvoidverification accuracy

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent implements self-service verification where the system automatically performs credential validation, data extraction, and authenticity verification without human intervention. The verification system autonomously validates cryptographic signatures, extracts relevant information using OCR, cross-checks against databases, and generates verification results, thereby eliminating human error while keeping technical requirements manageable through automated workflows.

Inventive Principle:

Principle #25Self-service

AI summary

An identity verification device for verification of a digital credential includes a user device communication interface for operative communication with a user device associated with a human user. The user device communication interface is operative to receive from the user device the digital credential of the human user stored locally on the user device. The device also includes a relying party communication interface operative to send a request to an intermediary credential service platform for verification of the digital credential presented by the user device, and to receive verification of the digital credential from the platform after application of an issuing authority credentialing standard to the digital credential. The device further includes a verification indicator operative to provide an indication of verification status of the digital credential to the relying party associated with the identity verification device.
