Aircraft Data Update System with Maintenance Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for updating data on computer devices in aircraft require an operator to be present in the cockpit, posing safety risks during maintenance operations, as some devices can affect safety during updating processes.
Innovation Solution
A system and method that include a data loading device, a communication device, a data router, and a module for detecting maintenance operations, which prevents data updates during maintenance by blocking commands and data transfers when a maintenance operation is detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data updating is performed remotely without operator presence, then productivity is improved, but safety deteriorates due to potential movement of movable elements during maintenance operations
Solution Approach 1:
The system performs preliminary detection of maintenance operations before allowing data updating to proceed. The detection module checks whether maintenance is being performed on the aircraft before the data loading device transfers updating data, preventing harmful movements during maintenance by blocking updates when maintenance is detected
Solution Approach 2:
The patent introduces a detection module as an intermediary between the data loading device and the computer device. This module detects maintenance operations and controls whether updating data can be transferred, acting as a safety mediator that prevents direct remote updating when maintenance personnel are present
2Object-affected harmful factors
If operator presence is required in cockpit for data updating, then safety is improved, but productivity deteriorates due to reduced updating efficiency
Solution Approach 1:
The system enables self-service remote updating by automatically detecting maintenance operations and controlling the updating process without requiring operator presence in the cockpit. The detection module and data loading device work together to autonomously prevent updates during maintenance while allowing them during normal operations
Solution Approach 2:
The detection module provides feedback about maintenance operation status to the data loading device. This feedback mechanism allows the system to automatically adjust whether updating data transfers are permitted based on real-time detection of maintenance activities, eliminating the need for manual operator oversight
