Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If machine learning techniques are used to analyze images for surface aberration detection, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improveaberration detection accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces a machine learning model as an intermediary component between the image capture system and the analysis output. This model is trained on labeled datasets of surface aberrations and serves as a specialized mediator that processes image data to identify subtle surface defects with high precision, resolving the contradiction by adding intelligence without requiring complex hardware modifications

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary action by pre-training the machine learning model on extensive datasets of surface aberrations before deployment. This pre-training phase creates a ready-to-use analytical engine that can immediately detect defects without requiring complex real-time processing infrastructure, thus improving measurement precision while managing device complexity

Inventive Principle:
Principle #10Preliminary action

2Productivity

If automated machine learning analysis is implemented, then productivity is improved, but device complexity increases

Engineering Contradiction:
Improveinspection efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The machine learning model operates autonomously to perform surface aberration detection without requiring manual inspection or complex control systems. The system self-services by automatically processing images, identifying defects, and generating results, thereby improving productivity while keeping the operational complexity manageable through automation rather than human intervention

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual inspection mechanisms with an automated machine learning-based image analysis system. This substitution eliminates the need for human inspectors and complex mechanical inspection devices, improving productivity by enabling rapid automated analysis while managing system complexity through software-based solutions rather than mechanical complexity

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

3Measurement precision

If detailed image analysis is performed to detect subtle aberrations, then measurement precision is improved, but loss of time increases

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The machine learning model is trained to recognize specific parameter patterns characteristic of surface aberrations (such as texture variations, color differences, and geometric anomalies). By changing the analysis parameters from general image processing to targeted feature detection, the system achieves high measurement precision while reducing analysis time through focused parameter evaluation rather than comprehensive image scanning

Inventive Principle:
Principle #35Parameter changes
