Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a centralized identity verification system is used, then authentication can be performed through installed programs or applications, but personal information may be leaked or abused

Engineering Contradiction:

Improveauthentication securityVSAvoidpersonal information leakage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a blockchain-based decentralized identifier (DID) system as an intermediary between users and authentication services. Instead of directly storing personal information in centralized systems, the DID system acts as a mediator that verifies identities through cryptographic proofs without exposing personal data, thus preventing information leakage while maintaining authentication reliability

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the traditional mechanical centralized verification system with a blockchain-based cryptographic system. Instead of relying on centralized databases and installed programs that are vulnerable to breaches, the system uses blockchain's immutable ledger and cryptographic signatures to verify identities, eliminating the need to store personal information centrally and thus preventing data leakage

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If a separate authentication program or application is installed for identity verification, then authentication can be performed, but the system becomes complex and compatibility issues arise with existing applications

Engineering Contradiction:

Improveidentity verification capabilityVSAvoidauthentication system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent creates a universal authentication system based on blockchain technology that can be integrated into multiple different applications and platforms without requiring separate installed programs for each service. The DID system provides a standardized interface that works across diverse applications, eliminating the need for multiple authentication programs and reducing system complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses digital copies of identity credentials in the form of verifiable credentials stored in electronic wallets. Instead of requiring users to install authentication programs, the system uses portable digital credential copies that can be presented and verified across different platforms, simplifying the authentication process while maintaining verification reliability

Inventive Principle:

Principle #26Copying

3Reliability

If users repeatedly authenticate across multiple platforms by entering ID and password, then each platform can verify user identity, but the process becomes cumbersome and time-consuming

Engineering Contradiction:

Improveplatform-specific authenticationVSAvoidauthentication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent merges multiple separate authentication processes into a single unified blockchain-based authentication system. By combining identity verification across multiple platforms through a common DID system, users only need to authenticate once with their electronic wallet, and the verification is automatically recognized across all participating platforms, eliminating repeated authentication steps and saving time

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Disclosed are a device and a method for providing an issuance service by using an open badge linked to blockchain-based academic achievement that reduce a user's trouble of generally visiting an educational institution or the educational institution's homepage to obtain a certificate, an educational qualification, or the like and submitting it directly to consumers (submitting institutions), by issuing and providing a blockchain-based open badge linked to the user's academic achievement such that the user (learner) is capable of proving his/her qualifications acquired through education, learning, examination, or the like provided by the educational institution (learning institution), thereby reducing the time required for issuance and submission as well as incidental costs while security is guaranteed.
