Variable RF Skin Treatment with Negative Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current skin treatment methods, such as negative pressure and radio frequency (RF) treatments, are limited in their ability to effectively target and remove cellulite and tighten skin, particularly in addressing the connective tissue bonds and varying tissue depths without causing excessive skin surface damage.
Innovation Solution
A system combining negative pressure and RF energy with a frequency controller that emits variable RF frequencies (0.8 MHz to 2.4 MHz) in controlled pulses to target specific tissue layers, applied in conjunction with adjustable suction pressure to enhance treatment efficacy and minimize skin surface exposure to electromagnetic radiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large amount of RF radiation is applied to target deep tissue layers, then the treatment effectiveness for deep cellulite and skin tightening is improved, but the skin surface may be damaged
Solution Approach 1:
The RF treatment is segmented into multiple frequency components (broadband spectrum from 0.5 MHz to 5 MHz) that can be independently controlled. This allows different frequency segments to target different tissue depths, with lower frequencies penetrating deeper and higher frequencies affecting shallower layers, thereby treating deep tissue without excessive surface exposure
Solution Approach 2:
Different RF frequencies are applied to different tissue depths with customized power levels. The system allows independent adjustment of power for each frequency component, enabling localized energy delivery matched to specific tissue depths and conditions, thus treating deep targets while protecting the skin surface
2Reliability
If negative pressure is applied to lift cellulite structure, then the connection between cellulite and skin is loosened, but the treatment time and pressure control complexity increase
Solution Approach 1:
Negative pressure is applied in periodic cycles rather than continuously. Each cycle includes phases of pressure application, release, and reversal, which mechanically manipulates the cellulite structure over time to loosen connective bonds. This periodic approach achieves effective loosening while allowing tissue recovery and simplifying control compared to continuous complex pressure regulation
3Device complexity
If single RF frequency is used for treatment, then the device complexity is reduced, but the ability to target different tissue depths effectively is limited
Solution Approach 1:
The system changes the frequency parameter of RF energy across a broad spectrum (0.5 MHz to 5 MHz) rather than using a single fixed frequency. By sweeping through multiple frequencies with adjustable power levels for each, the system can selectively target different tissue depths and types, achieving versatile multi-depth treatment while maintaining manageable device complexity through software-controlled frequency synthesis
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
The system effectively loosens cellulite bonds, targets subcutaneous adipose tissue, and tightens skin by selectively applying RF frequencies and pressure, improving treatment outcomes for cellulite removal and skin contouring while minimizing skin damage.
Implementation Method 1
radio frequency (RF) treatment. This treatment is used by selecting an area of tissue and applying electro-magnetic radiation to this area. The electro-magnetic radiation is applied at a radio frequency. The RF treatment dissolves the fatty tissue beneath the selected area of tissue and breaks down the connective bond
Implementation Method 2
The use of negative pressure in skin treatment is known. Negative pressure is used to provide pressure to the soft tissue at a specific location of the skin, and to lift the cellulite structure that is located beneath the skin. The pressure loosens the connection between the cellulite and the skin
