VSEngineering Contradiction Analysis

1Measurement precision

If manual testing methods are used for component carrier quality assessment, then human engineers can perform detailed inspection, but the process involves high effort and limited precision

Engineering Contradiction:
Improvequality testing precisionVSAvoidthroughput
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent replaces manual mechanical inspection with an automated system comprising a material removal unit, detection unit, and evaluation unit. The material removal unit automatically exposes internal planes, the detection unit captures images, and the evaluation unit with AI algorithms automatically identifies and evaluates defects, eliminating manual intervention entirely and achieving both high precision and high throughput

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

Solution Approach 2:

The system enables self-service quality testing where the component carrier itself is processed through automated material removal and self-inspection. The evaluation unit autonomously analyzes the exposed planes, identifies defects, and generates quality assessments without requiring human engineers, thereby increasing both precision and productivity simultaneously

Inventive Principle:
Principle #25Self-service

2Productivity

If manual cross-sectioning and inspection methods are used, then detailed internal structure analysis is possible, but the process is labor-intensive and has limited throughput for industrial scale

Engineering Contradiction:
