Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional insulator structure is used in probe base, then manufacturing is simple, but energy loss increases and measurement accuracy deteriorates during high-frequency signal testing
Solution Approach 1:
The insulator is designed with multiple through-holes penetrating from the first surface to the second surface, creating a porous structure that reduces signal reflection loss and improves impedance matching during high-frequency signal transmission, thereby reducing energy loss while maintaining measurement accuracy
Solution Approach 2:
The insulator structure parameters are optimized by controlling the total area of through-holes to fall within 0.6A-0.8A (where A is the area of the first surface without the probe mounting hole), and by arranging through-holes in specific patterns, to achieve optimal impedance matching and minimize energy loss at high frequencies
2Reliability
If conventional insulator structure is used in probe base, then device complexity is low, but signal reflection loss increases during high-frequency testing
Solution Approach 1:
The insulator incorporates multiple through-holes forming a porous structure that improves impedance matching and reduces signal reflection loss during high-frequency signal transmission, enhancing signal transmission quality while maintaining reasonable structural complexity
Solution Approach 2:
The insulator structure is segmented into multiple functional regions: a probe mounting hole at the center, multiple through-holes distributed in specific patterns, and coplanar first and second surfaces, with the total through-hole area controlled at 0.6A-0.8A to optimize performance
3Measurement precision
