Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gas delivery systems face challenges in minimizing gas breakdown when transitioning from low to high voltage, which limits design flexibility and can cause equipment failure and safety hazards due to high electric fields.
Innovation Solution
A reentrant gas delivery system with a tilted helical conduit design that experiences electric field reversals, arresting breakdowns and allowing for flexible conduit design by progressing through multiple equipotential lines and returning by fewer lines per winding, reducing the risk of gas breakdown.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gas is delivered directly from low voltage to high voltage through a straight conduit, then the delivery path is simple and design is flexible, but gas breakdown occurs due to high electric fields
Solution Approach 1:
The conduit is configured in a helical or curved path between low and high voltage regions, causing the gas to experience multiple electric field reversals as it traverses the winding path. This curvature transforms the straight-line delivery into a multi-directional path that naturally reduces breakdown risk through repeated field direction changes.
Solution Approach 2:
The gas delivery path is extended from a simple linear dimension into a three-dimensional helical trajectory. By adding spatial complexity in multiple dimensions, the conduit allows gas to progressively navigate through equipotential lines and experience field reversals without requiring additional components or complex mechanisms.
2Reliability
If constraints are imposed to prevent gas breakdown, then gas breakdown is reduced, but design flexibility of the gas delivery system is reduced
Solution Approach 1:
The conduit design allows for dynamic configuration of the helical path parameters (radius, pitch, number of windings) to optimize performance for different operating conditions. This dynamic adaptability enables the same basic principle to serve multiple design requirements while maintaining breakdown prevention through the fundamental helical field-reversal mechanism.
