Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high-frequency skin treatment devices using monopolar and bipolar types separately require cumbersome handpieces, leading to inefficient treatment, difficulty in focusing energy, and increased pain due to deep penetration, while existing methods struggle to effectively induce collagen production and strengthen the basement membrane, resulting in issues like freckles and decreased skin elasticity.
Innovation Solution
A method and device that sequentially apply monopolar and bipolar pulsed high frequencies in a 2:8 ratio through a single handpiece, using a conversion unit to switch between electrode types, accompanied by a cooling and muscle stimulation unit to enhance collagen production and basement membrane strength, reducing pain and improving skin elasticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If monopolar high frequency is applied to provide deep penetration and wide area treatment, then the treatment area coverage is improved, but the pain and physical fatigue increase
Solution Approach 1:
The patent applies periodic pulsed high frequency waves instead of continuous waves. The treatment alternates between monopolar and bipolar modes in a periodic sequence, allowing deep penetration when needed while providing rest periods that reduce cumulative pain and fatigue in the treated area.
Solution Approach 2:
The patent dynamically changes the polarity parameter between monopolar and bipolar configurations. By switching between these two polarities in sequence, the system achieves deep area coverage when monopolar is active while reducing pain through bipolar alternation, effectively modifying the harmful effects through parameter variation.
2Reliability
If separate handpieces are used for monopolar and bipolar treatments, then the specialized treatment effects are achieved, but the device complexity and treatment efficiency deteriorate
Solution Approach 1:
The patent combines both monopolar and bipolar electrode configurations into a single handpiece. The handpiece contains multiple electrodes that can be selectively activated to produce either monopolar or bipolar high frequency fields, eliminating the need for separate handpieces while maintaining the reliability of both treatment modes.
Solution Approach 2:
The single handpiece is designed with multi-functionality to perform both monopolar and bipolar treatments. By integrating switching circuitry and multiple electrode arrangements, the device can adapt to different treatment requirements, providing universal functionality that reduces device complexity while maintaining treatment effectiveness.
3Length of stationary object
If monopolar high frequency penetrates deeply into the skin, then the dermis and internal fat layers are affected, but the heating area cools down during mode switching
Solution Approach 1:
The patent implements continuous alternating action between monopolar and bipolar modes without complete interruption. The rapid switching between modes maintains continuous energy delivery to the tissue, preventing the heated area from cooling down during transitions. This continuous useful action ensures temperature stability while achieving deep penetration effects.
Solution Approach 2:
The periodic alternation between monopolar and bipolar high frequency application creates a rhythmic heating pattern. This periodic action prevents thermal dissipation by ensuring that before the heated area can cool down, the next pulse arrives to reheat it, thereby maintaining stable temperature in the deep dermal and fat layers throughout the treatment.
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 method promotes new collagen production, thickens and strengthens the basement membrane, reduces freckles, and enhances skin elasticity by evenly distributing high-frequency energy, minimizing pain and simplifying treatment procedures.
Implementation Method 1
a high frequency generation unit for transmitting high frequency generated in the electrode unit
Implementation Method 2
the monopolar type has the advantage of having a wide and deep area to which high frequency is applied. In particular, through this monopolar, high frequency energy may sufficiently reach the dermis layer
Implementation Method 3
the bipolar type may apply high-frequency energy intensively to the desired treatment area (mainly the upper part of the dermis)
Implementation Method 4
a conversion unit for converting the first electrode and the second electrode so that the electrode unit applies a monopolar type pulsed high frequency or a bipolar type pulsed high frequency
