Solution Overview

Problem

Current traceability systems in aircraft configuration management face challenges such as security risks due to long-range electronic labels, weight constraints, and unreliable communication in aeronautical environments, as well as limitations in encryption and authentication capabilities, leading to potential use of defective or counterfeit components and inefficient data management.

Innovation Solution

A method involving on-board wireless electronic labels and a wireless mesh network that securely communicates with an external installation, using UHF range and Zigbee protocol, to provide real-time monitoring and secure data transfer, with active, semi-active, and passive labels chosen based on component accessibility and environmental factors, ensuring secure and automatic data updates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of stationary object

If long-range electronic labels are used for traceability, then reading distance is improved, but security risks increase due to signal interception and decryption

Engineering Contradiction:
Improvereading distanceVSAvoidsecurity risks
Core Design Contradiction:
Length of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a wireless mesh network as an intermediary between the electronic labels and external readers. The mesh network acts as a mediator that routes signals through multiple nodes, making direct interception difficult while maintaining extended reading capability. The network infrastructure itself becomes the security barrier.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The communication system is segmented into multiple hierarchical levels: electronic labels at the component level, local readers at the component group level, routers at the section level, and a central server at the fleet level. This segmentation distributes security responsibilities across multiple layers, making single-point interception ineffective.

Inventive Principle:
Principle #1Segmentation

2Reliability

If heavy installation with gantry readers is deployed, then reading capability is improved, but device complexity and installation burden increase

Engineering Contradiction:
Improvereading capabilityVSAvoidinstallation burden
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system enables self-service reading where components can be read by any authorized device within the mesh network without requiring specialized gantry installations. The wireless mesh infrastructure is distributed throughout the facility, allowing maintenance personnel to read components using portable devices.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent transitions from a vertical gantry-based reading system to a horizontal distributed mesh network. Instead of requiring readers at fixed positions above components, the system distributes reading capability across multiple nodes throughout the three-dimensional space, eliminating the need for heavy gantry structures.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If manual entry of traceability data is used, then ease of operation is improved, but error risks increase

Engineering Contradiction:
Improvedata entry simplicityVSAvoiddata accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system automatically captures traceability data from electronic labels and transmits it to the central server through the wireless mesh network. The server validates and stores the data, providing automatic feedback that eliminates manual entry errors while maintaining operational simplicity through automated data collection.

Inventive Principle:
Principle #23Feedback

4Ease of operation

If updates are performed manually on timed basis, then ease of operation is improved, but productivity decreases due to tedious consultations

Engineering Contradiction:
Improveupdate simplicityVSAvoiddata consultation efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The wireless mesh network enables continuous automated data collection and transmission. Instead of periodic manual updates, the system maintains continuous connectivity between components, readers, and the central server, ensuring traceability data is always current and accessible without interrupting maintenance operations.

Inventive Principle:
Principle #20Continuity of useful action
