Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image processing is performed to detect chip locations based on luminance differences before and after machining, then chip detection capability is improved, but control processing time and complexity increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-dividing the machine tool interior space into grid regions before machining operations. This allows the system to quickly map chip locations to specific grid regions without performing complex full-image processing, significantly reducing control processing time while maintaining detection accuracy.
Solution Approach 2:
The patent segments the machine tool interior into multiple grid regions, transforming the complex task of analyzing entire images into simpler regional assessments. This segmentation enables parallel processing and reduces the computational burden, addressing the time complexity issue while preserving chip detection capability.
2Reliability
If template images and luminance thresholds are generated for each workpiece to account for environmental variations, then detection reliability is improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent changes the detection parameter from absolute luminance values to relative changes within grid regions. By focusing on luminance change ratios rather than absolute values, the system adapts to environmental variations without requiring complex template generation and threshold adjustment for each workpiece, reducing device complexity while maintaining reliability.
Solution Approach 2:
The system performs self-adjustment by automatically adapting to environmental conditions through grid-based relative measurement. Instead of requiring external calibration with template images for each workpiece, the system self-regulates by comparing luminance changes within its own grid framework, simplifying the overall system complexity.
3Adaptability or versatility
If comprehensive image processing is performed to capture various chip and environment combinations, then detection versatility is improved, but calculation time and processing power requirements increase
Solution Approach 1:
The patent applies partial action by focusing image processing efforts only on grid regions where chip presence is suspected or where luminance changes indicate chip accumulation. Instead of processing entire images comprehensively, the system selectively analyzes relevant regions, reducing processing time while maintaining versatility in detecting various chip types and environmental conditions.
