Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical identity documents are used for verification, then identity verification can be performed, but security is compromised and fraud is prone

Engineering Contradiction:

Improveidentity verification securityVSAvoididentity theft and fraud risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent creates digital copies of physical identity documents in the form of NFTs (non-fungible tokens) on a blockchain. These digital copies contain the same verification information as physical documents but are secured by cryptographic technology, making them tamper-proof and resistant to fraud while maintaining verification functionality.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical/physical identity verification system with a digital blockchain-based system. Instead of relying on physical document security features that can be counterfeited, the system uses cryptographic hashing, digital signatures, and decentralized ledger technology to provide superior security and fraud resistance.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If multiple physical identity documents are issued to individuals, then various identification needs are met, but system complexity and verification difficulty increase

Engineering Contradiction:

Improveidentity document varietyVSAvoidverification system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal digital identity system where a single NFT-based identity can serve multiple verification purposes across different platforms and jurisdictions. The blockchain-based identity contains standardized data structures that can be verified by any system supporting the protocol, eliminating the need for multiple specialized physical documents.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent transforms identity documents from physical form factors with varying security levels to a unified digital format on blockchain. By changing the underlying technology parameter from physical materials to cryptographic protocols, the system achieves both versatility and simplified verification through standardized digital validation processes.

Inventive Principle:

Principle #35Parameter changes

3Loss of information

If physical identity documents are used, then identity information can be stored, but tampering and counterfeiting are possible

Engineering Contradiction:

Improveidentity information integrityVSAvoiddocument authenticity

Core Design Contradiction:

Loss of informationVSReliability

Solution Approach 1:

The patent performs preliminary cryptographic hashing and digital signing of identity information when the NFT is created. This preliminary action embeds tamper-evident security features directly into the digital identity, so any subsequent modification would be immediately detectable through cryptographic verification, preventing undetected tampering.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces the blockchain as an intermediary layer between identity information storage and verification. The decentralized ledger acts as a trusted mediator that immutably records identity data and verification transactions, providing cryptographic proof of authenticity without requiring centralized authorities or complex physical security features.

Inventive Principle:

Principle #24Intermediary (Mediator)
