Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual borescope inspection is used, then inspector expertise can be utilized, but inspection time is prolonged and defect detection accuracy decreases due to inspector fatigue

Engineering Contradiction:
Improvedefect detection accuracyVSAvoidinspection time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces the manual mechanical inspection process with an automated computer-based system that captures borescope video feeds, processes them through machine learning models, and automatically identifies defects. This substitution eliminates inspector fatigue and consistently maintains high detection accuracy while significantly reducing inspection time.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service inspection by automating the defect detection process without requiring continuous human intervention. The machine learning models independently analyze video feeds, identify defects, and generate inspection reports, allowing the inspection system to serve itself and eliminating the time-consuming manual review process.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If comprehensive video analysis is performed to ensure accurate defect detection, then defect detection accuracy improves, but processing time increases

Engineering Contradiction:
Improvedefect detection accuracyVSAvoidinspection throughput
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The system performs preliminary actions by pre-processing video feeds and pre-training machine learning models with extensive defect data before actual inspection. This preliminary preparation enables the system to quickly analyze videos during inspection without compromising accuracy, as the heavy computational work has already been done in advance.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces manual video analysis with automated machine learning-based analysis that can process multiple video feeds simultaneously. This substitution enables comprehensive analysis of all inspection data without the time constraints of manual review, maintaining high defect detection accuracy while increasing overall inspection throughput.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If digital grid overlay is implemented for standardized imaging, then measurement precision improves, but system complexity increases

Engineering Contradiction:
Improveimaging standardizationVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces a digital grid overlay as an intermediary layer between the borescope video feed and the defect analysis process. This digital grid serves as a mediator that standardizes the imaging without requiring physical modifications to the borescope or engine, achieving measurement precision through software-based coordination rather than hardware complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)
