Solution Overview
Problem
Conventional plasma generating systems face challenges in reducing microwave energy leakage and electrode tip erosion due to the design of ignition systems that interfere with microwave energy in the nozzle, leading to reduced lifespan and inefficiency.
Innovation Solution
A plasma generating system with movable electrodes and a gate mechanism that slides to control the electrode's position, forming a gap to ignite plasma while minimizing microwave leakage by retracting the electrodes once plasma is established, using resilient members to close the opening and reduce aperture size, thereby preventing microwave leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional ignition system with a stationary electrode tip is used in the nozzle, then plasma can be ignited, but the electrode tip is eroded by microwave energy causing shortened lifespan and microwave leakage
Solution Approach 1:
The electrode is changed from a stationary component to a movable one that can be retracted into the nozzle. The electrode holder allows the electrode to move between an extended position (for plasma ignition) and a retracted position (for protecting from erosion and preventing leakage), transforming a static system into a dynamic one that adapts to different operational phases
Solution Approach 2:
The electrode is retracted into the nozzle before plasma ignition occurs. This preliminary positioning ensures that when high voltage is applied, the electrode tip is already in the optimal position for ignition, and after ignition, it can be quickly retracted to prevent erosion and leakage before they become problematic
2Productivity
If the electrode is moved into the nozzle for plasma ignition, then plasma can be generated, but the opening may allow microwave energy to leak
Solution Approach 1:
The gate is implemented as a movable component that can open and close dynamically. When the electrode needs to be inserted for plasma generation, the gate opens to accommodate it. When plasma is established and the electrode is retracted, the gate closes to seal the opening and prevent microwave energy leakage, thus dynamically managing the trade-off between plasma generation and energy containment
Solution Approach 2:
The gate acts as an intermediary component between the electrode holder and the nozzle opening. It provides a sealing mechanism that can accommodate the electrode during insertion while preventing leakage when the electrode is retracted, mediating between the need for electrode access and the need for energy containment

Function Achieved in This Case
The system effectively ignites plasma while reducing microwave leakage and electrode tip erosion, enhancing the overall efficiency and extending the lifespan of the electrodes by retracting them after plasma formation.
Implementation Method 1
a resilient member secured to the gate and adapted to generate a force to close the opening
Implementation Method 2
The distal ends are adapted to move into an opening of the gate as the electrode holder slides along a direction on the surface and adapted to generate an electric arc to thereby ignite plasma in a gas
