Innovation Solution

Implementing trust-aware mechanisms that incorporate trust evaluation into resource provisioning processes, using smart contracts and distributed ledger services to manage task assignments and executions, allowing for conditional acceptance, replacement, and migration of tasks based on trust criteria.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If decentralized resource provisioning is implemented in 6G networks, then scalability and robustness are improved, but trust management complexity increases

Engineering Contradiction:

ImprovescalabilityVSAvoidtrust management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a distributed ledger service as an intermediary layer between task requesters and resource providers. This mediator automatically records and verifies task assignments, resource allocations, and trust evaluations on an immutable ledger, eliminating the need for complex peer-to-peer trust negotiation while enabling scalable decentralized operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transforms trust management from a complex qualitative assessment into quantifiable parameters stored on the distributed ledger. By representing trust relationships as structured data with specific attributes (trust scores, verification status, temporal validity), the system simplifies trust evaluation while maintaining scalability across numerous entities.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If trust evaluation criteria are incorporated into resource provisioning, then reliability is improved, but processing time increases

Engineering Contradiction:

ImprovetrustworthinessVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent performs trust evaluations and resource availability checks in advance, storing the results on the distributed ledger before actual task execution. By pre-validating trust criteria and caching evaluation outcomes, the system ensures reliability through thorough assessment while minimizing processing time during actual task assignment operations.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements continuous feedback loops where trust evaluations are updated based on past task performance recorded on the distributed ledger. This feedback mechanism allows the system to maintain high reliability through ongoing verification while reducing processing time by leveraging historical data and established trust patterns rather than re-evaluating from scratch.

Inventive Principle:

Principle #23Feedback

3Extent of automation

If smart contracts are used for task assignment, then automation is improved, but system complexity increases

Engineering Contradiction:

Improvetask assignment automationVSAvoidsmart contract complexity

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The patent divides the complex task assignment process into separate modular smart contracts, each handling specific functions such as trust verification, resource allocation, task execution monitoring, and payment settlement. This segmentation reduces individual contract complexity while maintaining high automation through coordinated execution of multiple specialized contracts on the distributed ledger.

Inventive Principle:

Principle #1Segmentation

4Productivity

If conditional task acceptance is implemented, then resource allocation efficiency is improved, but communication overhead increases

Engineering Contradiction:

Improveresource allocation efficiencyVSAvoidcommunication overhead

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The patent enables resource providers to set their own conditional acceptance criteria and automatically evaluate incoming task requests against these pre-defined conditions. The distributed ledger automatically records acceptance decisions and updates resource availability status without requiring manual communication between parties. This self-service approach improves resource allocation efficiency while minimizing communication overhead by eliminating redundant verification exchanges.

Inventive Principle:

Principle #25Self-service

AI summary

In some implementations, a first entity may receive, from a second entity, a task assignment request including one or more of: an identifier of a first task, identifier of the first and second entity, execution instructions, set of trust evaluation criteria, a first smart contract, a specified trust level, a drafted first smart contract, and a preferred. The first entity may analyze requirements for executing the first task, decide on resource requirements for executing the first task and accept, conditionally accept, or reject the request based on the resource requirements and the set of trust evaluation criteria. The first entity may send a modified first smart contract when the first smart contract is conditionally accepted. The first entity may receive a notification that the first smart contract or modified first smart contract is recorded in a distributed ledger system via a DLS and may execute a first task accepted/conditionally accepted.
