Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional elution test methods are used to evaluate alkali deposits and silica peeling, then measurement precision is improved, but testing time and process complexity increase significantly
Solution Approach 1:
The patent replaces complex chemical elution tests with optical imaging and image contrast analysis. Instead of performing time-consuming chemical procedures to evaluate alkali deposits and silica peeling, the system uses an imager to capture surface images and analyzes contrast values to quickly assess deterioration levels, achieving comparable evaluation accuracy in a fraction of the time
Solution Approach 2:
The patent creates an optical copy (image) of the glass container surface and analyzes this copy to evaluate deterioration. By imaging the surface and analyzing contrast in the image data, the system obtains evaluation results without physically contacting or chemically treating the sample, thereby eliminating the need for lengthy elution tests while maintaining measurement precision
2Measurement precision
If conventional elution test methods are used to evaluate glass container quality, then measurement precision is improved, but device and process complexity increase
Solution Approach 1:
The patent substitutes complex chemical testing equipment and multiple-step elution procedures with a simplified optical imaging system. The imaging device captures surface characteristics, and image processing algorithms analyze contrast to determine deterioration levels, replacing elaborate laboratory apparatus with a more compact and easier-to-operate system
Solution Approach 2:
The system uses the optical properties of the glass surface itself to evaluate deterioration. By analyzing natural variations in light reflection and absorption on the container surface, the method extracts deterioration information without requiring external chemicals or complex sample preparation, thereby simplifying the overall testing system
3Measurement precision
If conventional elution test methods are used, then measurement precision is improved, but ease of operation deteriorates due to multiple steps and quality guarantee requirements
Solution Approach 1:
The patent replaces manual chemical elution procedures with automated optical imaging and image analysis. The system automatically captures images, processes the image data to calculate contrast values, and determines deterioration levels without requiring operators to perform multiple manual steps, thereby significantly improving ease of operation while maintaining evaluation accuracy
4Measurement precision
If conventional elution test methods are used, then measurement precision is improved, but productivity decreases due to time-consuming quality guarantee tests
Solution Approach 1:
The patent replaces time-consuming chemical elution tests with rapid optical imaging and image analysis. The imaging process captures surface characteristics instantly, and automated image processing algorithms quickly calculate contrast values to determine deterioration levels, achieving the same evaluation accuracy in a fraction of the time and thereby significantly improving testing efficiency and productivity
