Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual inspection is used to evaluate radiographic image quality, then the evaluation can be performed with simple equipment, but the inspection time is long and the results are subjective
Solution Approach 1:
The patent replaces the manual mechanical inspection process with an automated image processing system that uses preprocessing, binarization, line detection, and counting algorithms to automatically evaluate radiographic image quality, thereby eliminating subjective human judgment and significantly reducing inspection time
Solution Approach 2:
The system enables self-service evaluation by automatically processing radiographic images through a sequence of operations including noise removal, contrast enhancement, binarization, and wire counting, allowing the image quality assessment to be performed autonomously without requiring skilled inspectors
2Ease of operation
If manual inspection is used to evaluate radiographic image quality, then the equipment requirements are simple, but the evaluation lacks objectivity
Solution Approach 1:
The patent replaces subjective manual evaluation with an objective automated system that applies consistent image processing algorithms (preprocessing, binarization, line detection) to quantify wire visibility and count, ensuring reproducible and unbiased quality assessments across different images and operators
Solution Approach 2:
The system transforms the qualitative assessment of image quality into quantitative parameters by converting images to binary form, detecting line patterns, and counting visible wires, thereby establishing an objective measurement scale for radiographic image quality evaluation
3Productivity
If automated image processing is used to evaluate radiographic images, then inspection time is reduced and objectivity is improved, but the device complexity increases
Solution Approach 1:
The patent divides the complex image evaluation task into distinct sequential modules: preprocessing (noise removal, contrast enhancement), binarization (thresholding), line detection (pattern recognition), and counting (quantification). This segmentation allows each module to be optimized independently while maintaining overall system efficiency
Solution Approach 2:
The system introduces intermediate processing steps (preprocessing and binarization) that simplify the raw radiographic image into a standardized binary format with enhanced contrast, making the subsequent line detection and counting operations more reliable and reducing the complexity of the final evaluation algorithm
