Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If refrigerant is used continuously to cool the high-frequency electrode, then cooling effect is improved, but refrigerant consumption increases and cost increases
Solution Approach 1:
The valve switches between open and closed states periodically based on temperature feedback, allowing refrigerant to flow only when the electrode temperature exceeds the preset threshold. This periodic action replaces continuous refrigerant flow, reducing refrigerant consumption while maintaining effective cooling when needed.
Solution Approach 2:
The temperature sensor continuously monitors the electrode temperature and provides feedback to the control unit, which then adjusts the valve state accordingly. This closed-loop feedback system ensures refrigerant is delivered only when cooling is necessary, optimizing both temperature control and refrigerant efficiency.
2Temperature
If refrigerant is used continuously to maintain low temperature, then cooling efficiency is improved, but internal temperature cannot be maintained low
Solution Approach 1:
The system dynamically adjusts the refrigerant flow rate by switching the valve between open and closed states based on real-time temperature conditions. This dynamic control allows the system to maintain low internal temperature more effectively compared to static continuous flow, improving overall cooling efficiency.
3Power
If high-frequency output is generated for skin treatment, then wrinkle improvement effect is improved, but heat generation causes pain and burns
Solution Approach 1:
The cooling system is activated in advance or simultaneously with high-frequency output generation, preparing the electrode and surrounding tissue for the thermal load. This preliminary cooling action prevents pain and burns before they occur, allowing safe delivery of high-frequency power for wrinkle treatment.
Solution Approach 2:
The refrigerant acts as an intermediary substance between the heat-generating electrode and the skin tissue, absorbing excess heat and preventing direct thermal damage to the skin while allowing the high-frequency treatment to proceed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents heat-related pain and burns, reduces refrigerant consumption, and enhances cooling efficiency by maintaining a low internal temperature through controlled refrigerant delivery and discharge.
Implementation Method 1
a valve coupled to the injection part and the discharge part and configured to block external air flowing in through the refrigerant delivery path and discharge the cooling gas to the outside through the discharge path while retaining the cooling gas, and configured to open and close according to a pressure of the cooling gas
Implementation Method 2
the refrigerant needs to be used continuously... since the refrigerant vaporizes quickly, the tip temperature rises quickly
