Solution Overview
Problem
Conventional methods for inspecting electrolytically refined metal deposition plates are prone to human error and fatigue, making it difficult to precisely determine the grade based on nodule sizes and distribution due to reliance on visual inspection.
Innovation Solution
An automated apparatus comprising a conveyor, inspection unit, loading robot, and unloading robot that captures surface images of the metal deposition plate using vision units with cameras and lighting, and a controller to estimate nodule sizes and distribution, enabling automatic grading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual inspection by worker is used, then device complexity is reduced, but measurement precision and reliability deteriorate due to human error and fatigue
Solution Approach 1:
The patent replaces the mechanical visual inspection system with an automated optical inspection system. Vision units (cameras) capture images of the metal deposition plate surface, and a controller automatically analyzes nodule sizes and distribution, eliminating human visual inspection while improving measurement precision and consistency.
Solution Approach 2:
The patent creates optical copies (images) of the metal deposition plate surface using vision units. These digital images serve as representations of the actual surface, allowing automated analysis of nodule characteristics without direct physical measurement or human visual assessment, thereby enhancing precision and reducing inspection time.
2Productivity
If automated vision unit inspection is implemented, then productivity and measurement precision improve, but device complexity increases
Solution Approach 1:
The patent substitutes manual inspection operations with automated optical and computational systems. Vision units capture surface images rapidly, and digital image processing algorithms automatically determine nodule sizes and distributions, enabling high-speed inspection while maintaining precision through computational analysis rather than manual assessment.
3Reliability
If manual visual grading is used, then device complexity is minimized, but reliability and measurement precision deteriorate due to worker fatigue and expertise variations
Solution Approach 1:
The patent replaces subjective human grading with objective automated analysis. The controller systematically measures nodule sizes and distributions from captured images using standardized algorithms, eliminating variability caused by worker fatigue and expertise differences. This computational approach provides consistent, reliable grading results that are not influenced by human factors.
Solution Approach 2:
The patent implements a feedback mechanism where the controller continuously analyzes images from vision units and provides graded results. The system can compare measured nodule characteristics against predetermined criteria and automatically determine grade levels, providing reliable and repeatable assessments that maintain consistency across multiple inspections.
