Vehicle Corrosion Analyzer for Early Design Risk Mitigation
Solution Overview
Problem
The complexity of identifying potential corrosion risks in aircraft manufacturing, particularly with the use of composite materials, leads to challenges in early detection and mitigation, as current methods often require late-stage design changes that are costly and time-consuming.
Innovation Solution
A corrosion risk analysis system comprising an extractor, predictor, aggregator, and risk analyzer identifies potential corrosion surfaces and contacts within a vehicle model, predicts corrosion risks, aggregates these risks across functional design units, and generates assessments to inform design changes and reduce corrosion risks early in the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If corrosion risk analysis is performed during the design phase using automated extraction and prediction systems, then the ability to early identify and mitigate corrosion risks is improved, but the device complexity increases due to the need for integrated software systems comprising extractors, predictors, aggregators, and analyzers
Solution Approach 1:
The corrosion risk analysis system is divided into distinct functional modules: an extractor that identifies material contacts, a predictor that assesses corrosion risks, an aggregator that consolidates risks by functional design unit, and an analyzer that generates assessments. This segmentation allows each component to perform its specific function efficiently while maintaining overall system reliability for early corrosion detection.
2Loss of time
If comprehensive corrosion risk analysis is integrated into the design phase, then the time and cost associated with late-stage design changes is reduced, but the manufacturing precision requirements increase to accurately identify material contacts and corrosion surfaces
Solution Approach 1:
The system performs corrosion risk analysis during the design phase before manufacturing begins. The extractor identifies material contacts and the predictor assesses corrosion risks preliminarily, allowing design modifications to be made early when changes are less costly and time-consuming, thereby reducing losses associated with late-stage changes.
3Measurement precision
If the system analyzes multiple material contacts and potential corrosion surfaces throughout the vehicle model, then the measurement precision of corrosion risks is improved, but the loss of time increases due to the comprehensive nature of the analysis across multiple functional design units
Solution Approach 1:
The aggregator combines individual corrosion risks from multiple potential corrosion surfaces and material contacts into aggregated corrosion risks by functional design unit. This merging approach maintains comprehensive measurement precision by considering all contacts while reducing the overall analysis time through consolidated risk assessment at the functional unit level.

AI summary
A method and apparatus for analyzing potential corrosion for a vehicle. Potential corrosion surfaces for the vehicle are identified using a model for the vehicle. The corrosion risks are predicted for each of the potential corrosion surfaces. The corrosion risks predicted are aggregated into a group of aggregated corrosion risks for a group of functional design units for the vehicle. A corrosion risk assessment for the vehicle is generated to identify a corrosion risk in the vehicle from the group of aggregated corrosion risks, and to enable a change in the model to reduce the identified corrosion risk.
