Aircraft Performance Detection via Customized Operational Messages

Solution Overview

Problem

Conventional aircraft maintenance methods, relying on fixed schedules, often result in delays and grounding due to the time-consuming nature of maintenance processes and the high cost of replacing expensive parts, which can lead to unnecessary replacements of functioning components and inefficient resource allocation.

Innovation Solution

A method involving the collection of aircraft operation data to generate customized messages that reflect key performance parameters, allowing for real-time monitoring and condition-based maintenance, thereby optimizing maintenance schedules and reducing unnecessary replacements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If maintenance is performed according to a fixed schedule, then the aircraft can avoid delay or grounding to some extent, but the cost is too high and expensive parts may be replaced unnecessarily when they are still functioning normally

Engineering Contradiction:

Improveaircraft availabilityVSAvoidmaintenance cost

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The system performs preliminary detection of component performance through customized messages that monitor operational parameters before failure occurs. By detecting performance trends in advance, the system enables proactive maintenance scheduling that prevents failures without requiring unnecessary replacements of functioning components, thus reducing maintenance costs while ensuring aircraft availability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system establishes a feedback loop where operational data is continuously collected, customized messages are generated based on performance parameters, and maintenance decisions are adjusted according to actual component condition. This feedback mechanism replaces fixed-schedule maintenance with condition-based maintenance, allowing expensive parts to be retained until truly necessary while ensuring reliable aircraft operation.

Inventive Principle:

Principle #23Feedback

2Ease of manufacture

If post-processing maintenance is used, then the aircraft can be maintained after failure occurs, but the aircraft is delayed or grounded due to the time-consuming nature of maintenance processes
