Solution Overview

Problem

Aircraft maintenance often requires multiple personnel, with outdated documentation and limited expert access, leading to inefficiencies and incorrect part replacements due to the complexity of coordinating maintenance operations across different locations and companies.

Innovation Solution

A method and system that allow a maintenance operator to access the aircraft's high-security man-machine interface from outside the secure zone, using secure communication links and servers to ensure up-to-date documentation and expert assistance, reducing the need for physical presence and improving maintenance efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple personnel are present in the aircraft cockpit and near the maintenance part, then maintenance operations can be performed, but the number of people required increases and coordination complexity increases

Engineering Contradiction:
Improvemaintenance operation efficiencyVSAvoidcoordination complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent creates a virtual copy of the cockpit's human-machine interface by capturing images or video streams from cockpit screens and transmitting them to a remote device. This allows the maintenance operator to view cockpit information remotely without physically being in the cockpit, thereby reducing the number of personnel required while maintaining operational efficiency

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent introduces a communication system as an intermediary between the cockpit and the maintenance operator. This intermediary transmits visual information and enables two-way communication, allowing the maintenance operator to interact with the cockpit system remotely and reducing coordination complexity among multiple personnel

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If documentation is stored in paper form or local computer systems, then access is simple, but the documentation may not be up to date and cannot be easily updated

Engineering Contradiction:
Improvedocumentation accessVSAvoiddocumentation accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent creates a digital copy of the aircraft documentation that is stored remotely and can be accessed through the communication system. This digital copy can be updated centrally and automatically transmitted to maintenance operators, ensuring they always have access to the most current information while maintaining ease of access through electronic delivery

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent enables preliminary updating of documentation before maintenance operations begin. Documentation can be prepared, verified, and uploaded to the remote system in advance, ensuring that maintenance operators receive accurate and up-to-date information before they need to use it, thereby improving documentation reliability

Inventive Principle:
Principle #10Preliminary action

3Reliability

If experts are physically present to resolve maintenance failures, then expert intervention is available, but it is difficult to get experts involved depending on location

Engineering Contradiction:
Improveexpert intervention availabilityVSAvoidexpert involvement complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent creates a virtual presence system where experts can remotely view the cockpit's human-machine interface and maintenance situation through transmitted visual information. This allows experts to provide guidance and intervention without physically traveling to the aircraft location, making expert availability independent of geographic location while reducing the complexity of coordinating expert travel and physical presence

Inventive Principle:
Principle #26Copying
