Solution Overview

Problem

Current methods for tracking the configuration and history of aircraft and vehicle parts lack standardization and accuracy, leading to unreliable records and increased maintenance efforts due to inconsistent record-keeping and potential falsification of part histories.

Innovation Solution

Implementing interlocking blockchain networks for vehicle configuration and activity history records and part history records, where information is recorded in blockchain networks and locked upon installation, ensuring data integrity and accessibility across distributed systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional record-keeping methods are used for tracking aircraft configuration and part history, then ease of operation is maintained, but reliability and accuracy of records deteriorate due to lack of standardization and potential falsification

Engineering Contradiction:
Improveaccuracy of part history recordsVSAvoidcomplexity of tracking system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system segments the tracking into two separate but interlocking blockchains: one for vehicle configuration/history and one for part history. Each blockchain independently records specific types of data, reducing the complexity of any single system while maintaining overall reliability through their cryptographic links.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces blockchain technology as an intermediary layer between the vehicle tracking system and part history system. This intermediary uses cryptographic hashes to link the two systems, ensuring data integrity without requiring direct integration, thus improving reliability while managing complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If manual inspection methods are used to determine current aircraft configuration, then device complexity is minimized, but loss of information increases due to inspection errors and incomplete tracking

Engineering Contradiction:
Improvecompleteness of configuration dataVSAvoidtime required for configuration verification
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system performs preliminary recording of all configuration changes and part installations in the blockchains as they occur. This preliminary action ensures that complete configuration data is already available before inspection is needed, eliminating information loss while reducing verification time to simple blockchain queries.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The interlocking blockchains provide continuous feedback about the current configuration state through their cryptographic links. When a part is installed or configuration changes, the system automatically updates both blockchains, providing real-time feedback that eliminates information gaps and reduces verification time.

Inventive Principle:
Principle #23Feedback

3Reliability

If centralized record-keeping systems are used for aircraft tracking, then ease of operation is maintained, but reliability deteriorates due to single points of failure and potential data manipulation

Engineering Contradiction:
Improveintegrity of configuration recordsVSAvoidsimplicity of record management
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The blockchain system serves multiple functions simultaneously: it acts as a distributed ledger, a cryptographic verification system, and an automatic audit trail mechanism. This multi-functionality improves reliability through decentralization while maintaining ease of operation through standardized blockchain protocols that simplify record management.

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

4Reliability

If frequent inspections are performed to verify current aircraft configuration, then reliability of configuration data is improved, but productivity decreases due to increased maintenance efforts

Engineering Contradiction:
Improveaccuracy of current configurationVSAvoidmaintenance efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system replaces physical inspection mechanisms with cryptographic verification through blockchain. Instead of manually inspecting aircraft configuration, the system uses cryptographic hashes and blockchain links to verify data integrity, improving reliability while dramatically increasing maintenance productivity by eliminating repetitive physical inspections.

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

AI summary

A method and apparatus for recording information for a part, such as history information for an aircraft part. A part history blockchain network comprises part history blockchains for the part that are configured to record the information for the part. Configuration and activity history information for the vehicle is recorded in vehicle configuration and activity history blockchains for the vehicle in a vehicle configuration and activity history blockchain network. A part installation notification is received by the part history blockchain network. The part installation notification identifies the part and indicates that the part is installed on the vehicle. The part history blockchains for the part are locked in response to receiving the part installation notification to prevent adding information for the part to the part history blockchains for the part for as long as the part is installed on the vehicle.
