Current treatment apparatuses lack real-time temperature monitoring and control, leading to potential thermal damage during energy-based treatments, as they often rely on unknown skin surface temperatures and insufficient energy transfer.
Innovation Solution
A treatment apparatus with a temperature measurement unit that measures the treatment location's temperature at a frequency of 30 Hz or higher, separate from energy delivery, and a control unit that adjusts energy transfer or activates a cooling unit based on measured temperatures to prevent surface tissue damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If light energy is irradiated to skin tissue for treatment, then treatment effectiveness is improved, but thermal damage to skin surface may occur
Solution Approach 1:
The system implements real-time temperature feedback control by continuously monitoring skin temperature during laser irradiation and dynamically adjusting the laser output power based on the measured temperature, thereby preventing thermal damage while maintaining treatment effectiveness
Solution Approach 2:
The system performs preliminary cooling of the skin surface before laser irradiation and maintains cooling during treatment to prevent thermal damage before it occurs, ensuring the skin surface is prepared and protected in advance
2Measurement precision
If temperature measurement is performed at high frequency (30 Hz or higher), then temperature monitoring precision is improved, but device complexity increases
Solution Approach 1:
The measurement unit is designed to perform multiple functions: it measures temperature at high frequency for precise monitoring, filters measurement values to remove outliers, and provides data for control decisions, all within a single integrated component that does not significantly increase device complexity
Solution Approach 2:
The system performs temperature measurement at a frequency higher than strictly necessary (30 Hz or higher), then selectively uses only the valid measurement values for control decisions, achieving high measurement precision while managing complexity through intelligent data processing
3Object-affected harmful factors
If cooling unit is activated to prevent thermal damage, then skin surface protection is improved, but treatment energy transfer may be insufficient
Solution Approach 1:
The system dynamically adjusts the cooling unit operation and laser energy delivery based on real-time temperature measurements, optimizing the balance between protecting the skin surface and ensuring sufficient treatment energy transfer throughout the procedure
Solution Approach 2:
The system changes operational parameters dynamically by adjusting laser output power and cooling intensity based on measured skin temperature, ensuring optimal protection and treatment effectiveness at different stages of the procedure
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
Enables precise control of the treatment scheme, improving treatment effectiveness while preventing thermal damage by ensuring accurate temperature monitoring and adjusting energy delivery accordingly.
Implementation Method 1
When light is irradiated to the skin tissue, the light penetrates into the skin and is absorbed into various tissues, such as collagen, hair follicles, and hemoglobin, located inside the skin according to the wavelength characteristics of the light. The absorbed light is converted into heat energy in the tissue to apply thermal damage to the corresponding tissue or transform the state of the tissue
Implementation Method 2
the treatment unit may be configured to transfer energy to the treatment location by irradiating a treatment light, and more specifically, the treatment unit may irradiate a laser for treatment having a wavelength corresponding to an infrared or near-infrared region to the treatment location
Implementation Method 3
The temperature measurement unit may be disposed so as not to come into contact with the treatment location during treatment, and may measure the temperature by receiving a radiation light radiated from the treatment location
