Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If known measuring devices (callipers, micrometers, comparators) are used to measure material removal depth, then measurements can be obtained, but precision and reproducibility are poor due to operator skill dependence and random factors
Solution Approach 1:
The measuring device performs self-alignment through the automatic positioning mechanism. The movable support adjusts its position automatically to align the measuring probe perpendicular to the object edge, eliminating the need for operator skill in alignment. This self-service capability ensures consistent, reproducible measurements across different operators and sessions.
Solution Approach 2:
The invention replaces manual mechanical alignment operations with an automatic positioning mechanism. The motor-driven movable support substitutes for the operator's manual positioning actions, providing precise and repeatable alignment that eliminates human variability and improves measurement reliability.
2Measurement precision
If depth comparators are firmly fixed to a support acting as a fixed reference, then measurements can be taken, but the measurement process becomes laborious and inconvenient requiring the object to be placed in an identical predetermined position for each measurement
Solution Approach 1:
Instead of fixing the comparator to a support and requiring the object to be positioned relative to it, the invention inverts the approach by fixing the object on a stationary support and making the comparator movable. This allows the measuring device to adapt to different object positions and shapes, greatly improving ease of operation while maintaining measurement accuracy.
Solution Approach 2:
The measuring device incorporates a movable support that can dynamically adjust its position along the object edge. This dynamic capability allows the device to accommodate various object shapes and sizes, eliminating the need for predetermined positioning and making the measurement process more convenient and flexible.
3Adaptability or versatility
If known measuring devices are used on objects of predetermined rectilinear shapes, then measurements can be obtained, but the devices are not suitable for objects of various shapes including circular plates where exact center knowledge is essential
Solution Approach 1:
The measuring device is designed with universal applicability to measure material removal depth on objects of various shapes including rectilinear, circular, and irregular forms. The movable support and automatic positioning mechanism allow the same device to accurately measure different geometries without requiring shape-specific adjustments or knowledge of object centers, achieving both versatility and precision.
