Solution Overview

Problem

Existing methods for certifying component properties of field devices in industrial plants are inefficient, as they rely on laboratory tests that do not accurately represent real-world conditions, and lack global uniformity, making it difficult for customers to ensure the devices' performance in their specific environments.

Innovation Solution

A method utilizing blockchain technology to create a tamper-proof evaluation system where field device component properties are assessed and validated by a network of subscriber nodes, allowing real-world experience data to be stored and shared, ensuring data integrity and security through checksums and validation processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If laboratory tests are used to certify component properties, then certification can be performed with standardized procedures, but the test results do not accurately represent real-world environmental conditions

Engineering Contradiction:
Improvecertification processVSAvoidcomponent property assessment
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent introduces a blockchain-based evaluation system as an intermediary between laboratory certification and real-world performance. Multiple evaluating entities (customers, system integrators, operators) act as mediators who provide feedback on actual component performance in real environments. This decentralized evaluation network bridges the gap between controlled lab conditions and unpredictable real-world conditions, providing more reliable assurance without replacing standardized certification.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The blockchain evaluation system serves multiple functions simultaneously: it stores certification data, collects real-world performance feedback, validates component properties across different environments, and provides globally accessible verification. This multi-functional platform allows the same system to support both standardized certification and real-world performance tracking, resolving the contradiction between ease of certification and reliability of assessment.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If regional certificates are issued by single test centers, then certification can be performed with localized expertise, but uniform global certificates are not established

Engineering Contradiction:
Improveregional certificationVSAvoidglobal uniformity
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent merges regional certification data from multiple test centers into a single unified blockchain system. Evaluation results from different regions are combined and stored together on the distributed ledger, creating a comprehensive global view of component performance. This integration maintains the benefits of localized expertise while establishing global uniformity through a shared evaluation platform that all regions contribute to and access equally.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The global certification system is segmented into independent evaluating entities that each contribute their local expertise and data. Rather than a single centralized authority, multiple independent evaluators (customers, integrators, operators) provide region-specific assessments that are then aggregated on the blockchain. This segmentation allows regional adaptability to be preserved while achieving global uniformity through the unified ledger that consolidates all regional inputs.

Inventive Principle:
Principle #1Segmentation

3Reliability

If blockchain technology is used to store evaluation data, then data integrity and security are improved, but the system complexity increases

Engineering Contradiction:
Improvedata integrityVSAvoidevaluation system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses blockchain technology to create immutable copies of evaluation data that are distributed across multiple nodes. Each evaluation record is copied and stored on the decentralized ledger, ensuring data integrity through cryptographic verification. This copying mechanism provides reliable, tamper-proof storage without requiring complex centralized security infrastructure, as the distributed nature of blockchain inherently provides security and integrity guarantees.

Inventive Principle:
Principle #26Copying
