Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional three-coordinate measurement is used, then measurement capability is provided, but detection efficiency is too low
Solution Approach 1:
The measurement device is segmented into multiple independent support columns (first, second, third support columns) positioned at different locations, each providing localized support and measurement capability. This segmentation allows parallel measurement operations at multiple points simultaneously, improving detection efficiency without requiring a single complex measurement system.
Solution Approach 2:
The gauge structure utilizes the workpiece's own geometric features (center hole, tapered holes) as self-positioning elements. The center column fits into the center hole and the guide pillars fit into the tapered holes, allowing the workpiece to automatically position itself without requiring complex external positioning mechanisms, thereby simplifying the device while maintaining measurement efficiency.
2Ease of operation
If simple positioning structure is used, then ease of operation is improved, but measurement precision is reduced
Solution Approach 1:
The positioning features (center hole and tapered holes) are pre-formed as integral parts of the workpiece during manufacturing. This preliminary action ensures that the positioning elements are already prepared and precisely located, allowing the measurement gauge to simply engage with these pre-existing features rather than requiring complex positioning operations, thus maintaining both ease of operation and measurement precision.
Solution Approach 2:
The invention replaces complex mechanical positioning adjustments with direct geometric fitting between the gauge components and workpiece features. The center column fits into the center hole and guide pillars fit into tapered holes through purely geometric constraints, eliminating the need for adjustable mechanical positioning mechanisms while maintaining high precision and operational simplicity.
