Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for assessing and managing structural damage in aircraft are inefficient due to human error, lengthy consultation times with Structural Repair Manuals, and the lack of detailed structural analysis, leading to conservative analysis, reduced repair options, and increased maintenance costs.
Innovation Solution
The iSRM system provides a web-based, automated platform for remote assessment and management of structural damage, using 3D models and sensors to detect and analyze damage, and generate electronic reports, allowing for more accurate and detailed structural analysis and improved damage disposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated damage assessment systems are implemented, then productivity and reduction of human error are improved, but device complexity increases
Solution Approach 1:
The system integrates multiple functions into a single automated platform: damage detection via sensors, 3D model generation, structural analysis, SRM consultation, and repair procedure generation. This multi-functional integration improves productivity while managing complexity through unified architecture.
Solution Approach 2:
The patent introduces an automated analysis engine as an intermediary between damage detection and repair decision-making. This engine performs structural analysis and consults SRM databases automatically, reducing human intervention and minimizing human error in the assessment process.
2Measurement precision
If detailed structural analysis is performed, then measurement precision and reliability are improved, but loss of time increases
Solution Approach 1:
The system performs preliminary automated structural analysis immediately upon damage detection, generating initial assessment results before human review. This preliminary action provides accurate measurements while reducing the time required for detailed analysis by pre-processing data automatically.
Solution Approach 2:
The patent replaces manual structural analysis with automated computational analysis using finite element methods and structural software. This substitution maintains high measurement precision while dramatically reducing the time required for detailed structural assessment.
3Reliability
If conservative analysis is used, then reliability is improved, but productivity and repair options are reduced
Solution Approach 1:
The system dynamically adjusts the level of conservatism in analysis based on the specific damage characteristics and structural context. Rather than applying fixed conservative limits, the automated analysis adapts safety factors and analysis depth to each case, maintaining reliability while enabling more repair options and improving productivity.
Solution Approach 2:
The patent changes key analysis parameters such as safety factors, load conditions, and material properties based on real-time structural assessment data. This allows the system to maintain appropriate reliability levels while avoiding unnecessarily conservative decisions that would reduce repair options and increase maintenance costs.
4Ease of operation
If manual SRM consultation is performed, then ease of operation is maintained, but loss of time and human error increase
Solution Approach 1:
The system enables self-service damage assessment by automatically consulting SRM databases and generating repair procedures without requiring manual lookup. The automated platform performs the consultation function independently, reducing time loss and human error while maintaining ease of operation through user-friendly interfaces.
Solution Approach 2:
The system provides automated feedback by comparing detected damage against SRM limits and criteria, then generating recommended repair procedures. This feedback loop eliminates manual consultation steps, reduces errors, and maintains operational simplicity by presenting clear, actionable results to users.

AI summary
Structural analysis automation allows the implementation of more detailed or accurate analysis methodology that reflects the actual behavior of the damaged or repaired structure and consequently improves the resulting damage disposition for example by Increasing the allowable damages and structural repairs applicability, increasing the allowable damage limits causing the reduction of unnecessary installation of structural repairs, optimizing repairs and increasing fly-by periods and inspection intervals.
