Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional size measuring device uses program logic designed by an engineer to detect edges and boundaries, then the device can operate with simple hardware and basic processing, but the measurement reliability deteriorates when errors occur in the program logic, leading to incorrect boundary detection
Solution Approach 1:
The patent replaces the conventional mechanical/logical edge detection system (based on program logic and threshold brightness values) with an artificial intelligence-based image recognition system. The AI model automatically identifies boundaries and features in images without relying on pre-programmed logic, thereby eliminating errors associated with manual program design while maintaining hardware simplicity.
2Productivity
If a conventional size measuring device uses threshold-based edge detection from brightness images, then the processing is fast and simple, but the measurement precision deteriorates when boundary lines are incorrectly detected
Solution Approach 1:
The patent substitutes the threshold-based edge detection algorithm with an AI-based image recognition system that automatically identifies boundaries and features. The AI model processes images to extract accurate dimensional information without relying on fixed brightness thresholds, thereby improving measurement precision while maintaining efficient processing speeds through automated feature extraction.
