Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complete image acquisition and complex image processing is used to determine edge coating properties, then measurement precision is improved, but processing time increases and productivity decreases
Solution Approach 1:
The patent extracts only the essential information needed for processing - specifically whether edge material is present and its basic type - rather than performing complete image acquisition and processing. This selective extraction of critical data eliminates unnecessary computational steps while maintaining sufficient detection accuracy for production decisions
Solution Approach 2:
Instead of performing full image processing, the system applies partial action by using simplified detection methods that capture only the necessary characteristics of edge coatings. This partial processing approach provides sufficient information for production control without the time cost of complete analysis
2Adaptability or versatility
If mechanical sampling or code reading is used to detect work piece properties, then adaptability is improved, but reliability decreases due to errors at high machine rates
Solution Approach 1:
The patent replaces mechanical sampling methods and code reading systems with optical detection. This substitution eliminates the mechanical contact and reading errors that plague high-speed operations, providing reliable detection without physical interaction with the work piece
Solution Approach 2:
The optical detection system allows work pieces to be detected in their natural state without requiring additional codes, markers, or mechanical sampling features. The system detects edge coating properties directly from the work piece itself, eliminating the need for auxiliary identification elements
3Manufacturing precision
If comprehensive image processing is performed to calculate complete profiles, then manufacturing precision is improved, but loss of time increases making it impractical at high conveyor speeds
Solution Approach 1:
The system extracts only the critical parameters needed for production decisions - primarily the presence and type of edge material - rather than calculating complete profiles. This selective data extraction maintains sufficient manufacturing precision for production control while dramatically reducing processing time
Solution Approach 2:
The patent applies partial action by performing only the minimum necessary detection and analysis to make production decisions. Instead of complete profile calculation, the system performs sufficient detection to identify edge material characteristics, providing adequate precision without excessive processing time
