Solution Overview

Problem

Current systems lack a trusted and centralized method for validating and recording aircraft trajectory information, leading to inconsistent and inaccurate representations due to disparate data sources and business interests, making it difficult to obtain a unique, synchronized, and accurate trajectory.

Innovation Solution

A method using blockchain technology to validate and record vehicle trajectory data by aggregating data from various sources, reconstructing trajectories using weather and performance models, fusing the data, and mining it to ensure validity before inserting it into a vehicle trajectory blockchain, providing a secure and tamper-proof database.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multiple trajectory data sources are used, then data coverage and accessibility are improved, but data consistency and trustworthiness deteriorate due to disparate representations and business interests

Engineering Contradiction:
Improvedata coverageVSAvoiddata consistency
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The system segments trajectory data validation into separate functional modules: data aggregation from multiple sources, trajectory reconstruction using weather and performance models, data fusion, and blockchain mining validation. Each module processes specific aspects of data consistency independently, allowing comprehensive data coverage while maintaining reliability through structured validation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The blockchain acts as an intermediary layer between multiple trajectory data sources and end users. It provides a neutral, trusted environment where aggregated and validated trajectory data is stored and exchanged, eliminating direct trust issues between disparate data sources while maintaining data consistency across the system.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If centralized trajectory validation is used, then data accuracy and trust are improved, but system complexity and centralization risks worsen

Engineering Contradiction:
Improvedata accuracyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system employs self-service validation mechanisms where the blockchain network itself validates and verifies trajectory data through distributed mining processes. Miners independently verify data blocks, and the cryptographic hashing mechanism automatically ensures data integrity, eliminating the need for complex centralized validation infrastructure while maintaining high data accuracy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces complex mechanical centralized validation systems with cryptographic and distributed computational mechanisms. Blockchain hashing, digital signatures, and distributed consensus algorithms substitute for traditional centralized validation infrastructure, reducing system complexity while enhancing reliability through mathematical guarantees rather than organizational hierarchy.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Quantity of substance

If trajectory data is aggregated from multiple sources, then data completeness is improved, but data processing complexity and validation difficulty worsen

Engineering Contradiction:
Improvedata completenessVSAvoidprocessing complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The system performs preliminary trajectory reconstruction and validation actions before data is finalized on the blockchain. Trajectories are reconstructed using weather models and aircraft performance data in advance, and validation rules are pre-established through the mining process, reducing the complexity of real-time processing while maintaining data completeness from multiple sources.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent transforms trajectory data through parameter changes during the aggregation and validation process. Data is standardized into统一 formats, validated against multiple criteria, and transformed into blockchain-ready structures through hashing and encryption, simplifying the final data representation while preserving completeness from diverse sources.

Inventive Principle:
Principle #35Parameter changes
