Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional skin care apparatuses are limited in their ability to deliver electric energy to the entire skin layer, reducing the effectiveness of treatments by focusing only on specific areas.
Innovation Solution
A bipolar current delivery apparatus with independently controlled first and second electrodes, capable of applying currents of different frequencies, allows for simultaneous or alternate delivery of electric energy to the entire skin layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional skin care apparatuses use single-frequency current delivery to specific skin areas, then the treatment focuses on targeted regions, but the electric energy cannot be delivered to the entire skin layer uniformly
Solution Approach 1:
The patent divides the electrode system into multiple independent electrode groups (first electrode group, second electrode group, third electrode group) that can be independently controlled. Each group can deliver current at different frequencies and to different skin depths, enabling uniform energy delivery across the entire skin layer while maintaining precise control over specific regions.
Solution Approach 2:
The patent applies different current frequencies to different electrode groups targeting different skin layers. The first electrode group delivers high-frequency current for deep dermal heating, the second electrode group delivers medium-frequency current for intermediate layers, and the third electrode group delivers low-frequency current for superficial layers, optimizing treatment for each specific skin layer.
2Productivity
If conventional apparatuses apply single frequency current, then the device complexity is low, but the treatment effectiveness for entire skin layer is reduced
Solution Approach 1:
The patent creates a multi-functional current delivery system where a single apparatus can deliver multiple frequency currents (high-frequency, medium-frequency, low-frequency) simultaneously or sequentially through different electrode groups. This universal system can treat various skin conditions and target different skin layers, significantly improving treatment effectiveness despite increased device complexity.
Solution Approach 2:
The patent implements dynamic control of current frequency and electrode activation. The control unit can dynamically switch between different frequency patterns and activate different electrode groups based on treatment requirements, allowing the system to adapt to various treatment scenarios and maximize therapeutic effect across the entire skin layer.
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
Enhances therapeutic effects by delivering electric energy uniformly across all skin layers, providing varied treatment outcomes through diverse current and frequency patterns.
Implementation Method 1
The apparatus that delivers high-frequency waves to skin tissues may repeatedly invade a deep portion (e.g., a dermis layer) of the skin (e.g., a face) with an RF needle electrode moving back and forth in a vertical direction, may remove damaged collagen, elastic fibers, or the like from the deep portion of the skin at a target point by using the heat generated by high-frequency waves
