Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional encryption technologies such as blockchain are used to protect digital assets, then general cyberattacks can be defended against, but high-level cyberattacks such as quantum computer cryptanalysis and EMP attacks can still breach the security

Engineering Contradiction:
Improvesecurity protection levelVSAvoidvulnerability to quantum attacks and EMP attacks
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments digital assets into multiple divided data pieces and distributes them across different storage locations. Even if some pieces are compromised by quantum attacks or EMP events, the complete asset remains protected as long as sufficient pieces survive. This segmentation approach transforms a single point of failure into a distributed resilience system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary recovery mechanism that acts as a mediator between the divided data pieces and the original digital asset. When data loss occurs due to high-level cyberattacks or physical destruction, the intermediary recovery system reconstructs the original asset from surviving pieces without requiring the complete original data, thus providing an additional layer of protection against quantum and EMP threats.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If digital assets are stored in centralized locations or single cloud services, then management is simplified, but the assets become vulnerable to single points of failure from attacks or system failures

Engineering Contradiction:
Improvedata management simplicityVSAvoidresistance to system failure and attacks
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent divides digital assets into multiple segments and distributes them across different storage locations and cloud services. This segmentation eliminates single points of failure while maintaining manageable complexity through automated distribution and recovery mechanisms. The system handles the complexity of distributed storage automatically, preserving ease of operation while enhancing reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the storage parameter from centralized to distributed architecture. By transforming the storage topology and using configurable distribution parameters, the system achieves both improved reliability through redundancy and maintained operational simplicity through parameter-based control of the distribution logic.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If data is distributed across multiple locations for security, then resistance to attacks improves, but data restoration becomes more complex

Engineering Contradiction:
Improveprotection against destructionVSAvoidrestoration system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a recovery contract as an intermediary that simplifies the restoration process. Instead of requiring complex manual coordination of multiple distributed data pieces, the recovery contract automatically mediates the reconstruction process by identifying surviving pieces and orchestrating their combination to restore the original digital asset, thus reducing restoration complexity while maintaining distributed security.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If quantum cryptography is introduced to protect against quantum computer attacks, then cryptographic security improves, but the cost and practical applicability remain prohibitive

Engineering Contradiction:
Improvecryptographic security levelVSAvoidimplementation cost and practicality
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies segmentation to divide digital assets into multiple encrypted pieces distributed across different locations. This approach provides quantum-resistant security through mathematical distribution rather than relying on expensive quantum cryptography hardware. The segmentation method achieves comparable security levels at significantly lower implementation costs and with broader practical applicability.

Inventive Principle:
Principle #1Segmentation

AI summary

[Problem] Provided is a system that strongly protects important information from high-level cyberattacks and physical destruction, such as cryptographic analysis using quantum computers and electromagnetic pulse attacks, and that may be restored without being stolen by a third party. [Solution] The system encrypts and multi-divides file data to be saved using a program having predetermined encryption and division algorithms based on the first parameter specified by a customer, allots each of the file data to multiple sets of distributed file management groups comprising node groups at multiple bases in different regions of the world, distributes and records the file data to be saved in the nodes located at each of the bases that belong to corresponding distributed file management groups, generates and encrypts index information of each of the distributed and recorded corresponding file data, and records the index information in node groups of a specified base in the consortium chain.
