Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conductivity probes experience instability in signal transmission due to high electric resistance and inductive effects, primarily caused by the complex structure and large size of the elastomer body, which affects the accuracy and efficiency of electronic current and signal testing.
Innovation Solution
The elastomer structure of the conductivity probe features a resilient section with plane-grounded arcuate ends and multiple coils surrounding the transceiver portions, allowing for stable contact and reduced resistance by mating coils during signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the elastomer body has arcuate ends for contact, then the probe can be flexible and adaptable, but signal transmission stability deteriorates due to high electric resistance and inductive effect
Solution Approach 1:
The patent applies local quality by differentiating the contact end geometry from the bulk elastomer properties. The contact ends are plane-ground to create flat, stable contact surfaces, while the resilient section maintains its elastic properties for flexibility. This localized modification of the contact surface quality resolves the contradiction between overall flexibility and contact stability.
2Reliability
If the probe structure is complex and large-sized, then conductivity and low resistance are achieved, but the probe becomes complicated and has high resistance value
Solution Approach 1:
The patent extracts the contact function from the bulk elastomer material and concentrates it into dedicated contact portions with plane-ground surfaces. This separation of the contact function from the flexible body reduces the complexity of the overall structure while maintaining good conductivity through the streamlined elastomer composition and direct contact paths.
3Ease of operation
If the transceiver portions have arcuate ends, then contact with signal terminals is achieved, but electric resistance increases and inductive effect is raised
Solution Approach 1:
The patent inverts the conventional arcuate contact end design by applying plane-ground flat surfaces instead. This inversion of the contact geometry fundamentally changes the contact mechanism from point/line contact to surface contact, thereby reducing contact resistance and eliminating the inductive effects associated with curved geometries.
