Solution Overview
Problem
Conventional high-frequency treatment devices face issues with rapid refrigerant vaporization leading to increased gas consumption, high costs, and inefficient cooling, which can cause heat-related pain and burns, and require continuous refrigerant use to maintain low internal temperatures.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If refrigerant is used continuously to cool the high-frequency electrode, then cooling effect is maintained, but refrigerant consumption increases and cost increases
Solution Approach 1:
The valve operates periodically based on pressure cycles: it closes when pressure reaches a reference level to retain cooling gas, and opens when pressure exceeds a threshold to discharge gas. This periodic operation replaces continuous refrigerant use with intermittent discharge, reducing overall refrigerant consumption while maintaining cooling effectiveness through pressure-regulated gas retention.
2Temperature
If refrigerant is used continuously to maintain low internal temperature, then cooling efficiency is maintained, but usage cost increases
Solution Approach 1:
The system uses pressure feedback control where the valve monitors internal pressure and adjusts its state accordingly. When pressure reaches a reference value, the valve closes to retain cooling gas; when pressure exceeds a threshold, it opens to discharge gas. This feedback mechanism optimizes refrigerant usage by maintaining cooling effect only when necessary, reducing energy waste and usage costs.
3Productivity
If valve opens completely to discharge cooling gas, then cooling gas discharge is efficient, but internal temperature rises quickly
Solution Approach 1:
The valve transitions from static to dynamic control, adjusting its opening degree based on real-time pressure conditions. The valve opens partially or fully depending on whether pressure is above the reference value or threshold, creating a dynamic response that balances discharge efficiency with temperature control. This dynamic adjustment prevents excessive temperature rise while maintaining adequate gas discharge.
4Speed
If valve opens quickly to discharge cooling gas, then gas discharge speed increases, but temperature control precision decreases
Solution Approach 1:
The system changes the valve opening parameter dynamically based on pressure conditions. Instead of fixed opening speed, the valve adjusts its opening degree and speed according to whether pressure is at reference level or above threshold. This parameter change enables precise temperature control by matching discharge speed to actual cooling needs, preventing both overheating and excessive cooling.
