Onboard Data Processing for Aircraft Maintenance Tagging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for maintaining aircraft configuration and maintenance history are inefficient, relying on paper records which are difficult to update and access, especially in remote locations without reliable communication, and automated identification technology tags face challenges in storage capacity and access control.
Innovation Solution
Implementing an onboard data processing system that uses automated identification technology tags to store and update part information, including maintenance history, allowing for local access and synchronization with off-board systems when communication is available, using a combination of identification tags for quick identification and onboard storage for detailed data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If automated identification technology tags are used to store part information, then access speed and ease of identification are improved, but storage capacity is limited
Solution Approach 1:
The information storage system is segmented into two parts: automated identification tags (RFID, barcodes) for quick identification and basic part information, and centralized database storage for detailed maintenance history and configuration data. This segmentation allows fast access for identification while offloading detailed storage to the centralized system, resolving the contradiction between access speed and storage capacity.
Solution Approach 2:
An onboard data processing system acts as an intermediary between the automated identification tags and the centralized off-board database. The intermediary retrieves data from tags, stores it locally when needed, and synchronizes with the off-board system when communication is available, enabling fast local access while maintaining comprehensive storage capacity.
2Quantity of substance
If paper records are used for maintenance history, then storage capacity is sufficient, but ease of operation and accessibility are worsened
Solution Approach 1:
The mechanical paper record system is replaced with an electronic data processing system that uses automated identification tags for quick part identification and a digital database for maintenance history storage. This substitution provides sufficient storage capacity like paper while dramatically improving accessibility through electronic search, retrieval, and display capabilities.
Solution Approach 2:
Instead of accessing original paper records, the system creates and maintains digital copies of maintenance history in a centralized database. These digital copies can be instantly retrieved, displayed, and updated without physical handling, improving ease of operation while maintaining comprehensive storage capacity.
3Measurement precision
If configuration information is updated manually, then accuracy can be maintained through careful review, but productivity and timeliness are reduced
Solution Approach 1:
The system enables self-service updating of configuration information through automated identification tags. When parts are installed or removed, the tags automatically provide identification information that triggers updates to the maintenance history and configuration database, eliminating manual data entry while maintaining accuracy through automated data capture.
Solution Approach 2:
The onboard data processing system continuously monitors part installation and removal events, automatically updating configuration information in real-time. The system provides feedback loops where maintenance operations trigger automatic updates, ensuring both accuracy through systematic tracking and timeliness through immediate updates without manual intervention.
4Ease of operation
If onboard data processing system is implemented, then accessibility in remote locations is improved, but device complexity increases
Solution Approach 1:
The onboard data processing system is designed to perform multiple functions: storing part information, tracking maintenance history, managing configuration data, and synchronizing with off-board systems. By consolidating these functions into a single multi-functional system rather than separate specialized systems, the complexity is managed while providing comprehensive accessibility in remote locations.
Data Source
AI summary
A method and apparatus for maintaining a vehicle. Identification information for a part on the vehicle is read from an automated identification technology tag, wherein the automated identification technology tag is on the vehicle and associated with the part. Part information for the part is retrieved from an onboard data processing system on the vehicle using the identification information for the part. The part information retrieved from the onboard data processing system may be displayed to a user. The part information stored onboard the vehicle may be synchronized with an off-board system.
