Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If blockchain technology is used for data management and transfer, then data security and integrity are improved, but system complexity and difficulty of integration with existing non-blockchain systems increase

Engineering Contradiction:

Improvedata securityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs cryptographic keys as intermediaries between blockchain and non-blockchain systems. These keys enable secure data extraction and transfer without requiring direct integration of the entire blockchain infrastructure into existing systems, thus maintaining security while reducing complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system segments the blockchain integration functionality into discrete cryptographic operations (key generation, key derivation, data extraction) that can be independently implemented and managed, rather than requiring full blockchain system integration.

Inventive Principle:

Principle #1Segmentation

2Reliability

If cryptographic keys are used to extract and transmit data from blockchain, then data extraction security is improved, but processing time and computational resources increase

Engineering Contradiction:

Improvedata extraction securityVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Cryptographic keys are generated and stored in advance before data extraction is needed. This preliminary key generation eliminates the need for complex cryptographic operations during actual data extraction, reducing processing time while maintaining security.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses public keys (which are copies or representations of the private key's cryptographic identity) for data verification and extraction. This allows secure data extraction without requiring access to or processing of the full private key, reducing computational overhead.

Inventive Principle:

Principle #26Copying

3Productivity

If manual data management processes are replaced with automated cryptographic systems, then operational efficiency is improved, but system complexity and implementation difficulty increase

Engineering Contradiction:

Improveoperational efficiencyVSAvoidimplementation difficulty

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The cryptographic key system is designed to be universal and adaptable to different blockchain platforms and existing non-blockchain systems. This multi-functionality allows the same key management approach to be applied across various systems without requiring custom implementations, reducing implementation difficulty.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system enables automated data extraction and verification using pre-generated cryptographic keys, allowing the system to service itself without requiring manual intervention for each data operation, thus improving efficiency while the complexity is confined to the initial key setup.

Inventive Principle:

Principle #25Self-service

4Adaptability or versatility

If blockchain data is integrated with non-blockchain computing systems, then system interoperability is improved, but data integrity and security guarantees may be compromised

Engineering Contradiction:

Improvesystem interoperabilityVSAvoiddata integrity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

Cryptographic keys serve as intermediaries that maintain the security and integrity guarantees of blockchain systems while enabling integration with non-blockchain systems. The keys act as a trusted bridge that preserves data integrity without requiring the non-blockchain system to inherit blockchain's full security model.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Techniques are presented for cryptographic secure processing, transmission and exchange of data. A computer implemented method is presented comprising associating one or more elements of a structure with a cryptographic sub-key derived from another cryptographic key, wherein the structure is formed by elements within a hierarchical entity, and the hierarchical entity has a plurality of elements organized or associated in a hierarchical relationship; extracting or copying, from a blockchain transaction, data comprising or relating to the cryptographic sub-key associated with the one or more elements; and transmitting the extracted data to a non-blockchain based computer system associated with the hierarchical entity.
