Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is no clear mechanism for determining whether an organization outside a consortium should be approved for participation, and for a new organization to join a sub-group in a consortium-type blockchain, ensuring reliability and efficiency in the affiliation process.

Innovation Solution

An organization management support system that includes a request unit to determine participation based on consensus from other organizations within the distributed ledger system, using a management unit to collect and finalize determination results, ensuring reliable affiliation processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a new organization joins a sub-group in consortium-type blockchain, then the business network expands and diversity increases, but the reliability and security of the distributed ledger system may be compromised

Engineering Contradiction:

Improveability of the business network to accommodate new organizationsVSAvoidreliability of the distributed ledger system

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary actions by requiring prospective members to undergo security assessments and obtain approvals from existing members before joining the sub-group. This preliminary vetting process ensures that only organizations meeting reliability standards are admitted, thus maintaining system reliability while enabling expansion.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces intermediary mechanisms including security assessment processes and approval workflows that act as mediators between new organizations and the existing sub-group. These intermediaries verify the credibility of new members before integration, resolving the contradiction between expansion and reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a centralized organization manages participation approval, then the reliability of member selection is improved, but the efficiency and decentralization benefits of blockchain are reduced

Engineering Contradiction:

Improvereliability of participation determinationVSAvoidefficiency of the affiliation process

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent segments the approval process into distributed tasks assigned to different existing sub-group members. Each member independently assesses and votes on prospective members, eliminating the need for a single centralized authority while maintaining collective reliability through distributed decision-making.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system implements feedback mechanisms where existing members provide assessments and votes on prospective members. This distributed feedback loop enables reliable participation determination without centralized control, as the collective wisdom of multiple members ensures quality approval while maintaining efficiency through parallel processing.

Inventive Principle:

Principle #23Feedback

3Reliability

If all organizations share the same ledger data, then transparency and trust are improved, but data confidentiality and security for specific organizations are compromised

Engineering Contradiction:

Improvetransparency and trust in transactionsVSAvoiddata confidentiality risk for organizations

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments the ledger into sub-ledgers that are distributed selectively to specific sub-groups based on their transaction relationships. This segmentation enables organizations to share data only with relevant partners, maintaining transparency within trusted circles while protecting confidentiality from unrelated organizations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system applies local quality by allowing different levels of data visibility for different organizations. Each organization receives ledger data appropriate to its specific transaction relationships and permissions, ensuring that data confidentiality is maintained locally for each organization while transparency is preserved within its relevant context.

Inventive Principle:

Principle #3Local quality

AI summary

A distributed ledger node of an organization management support system includes a request unit configured to request a determination on participation to a business network from a node of another organization on a distributed ledger system when receiving a request for new participation to a business network from a node of a specific organization, and a management unit configured to collect a determination result of at least the node of the other organization, finally determine the participation on the basis of the collected result, and reply to the node of the specific organization with a result of the final determination.
