Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atmospheric plasma devices for skin treatment face issues such as electrical shock and limited effectiveness due to the direct contact of electrons with the skin, requiring anesthetic creams and having limitations in generating plasma at closer distances.
Innovation Solution
An atmospheric plasma device with a voltage electrode, a ground electrode, and a dielectric barrier that shields the voltage electrode, featuring a disk and shield plate configuration with off-axis spray holes to prevent electrical shock by ensuring all plasma passes through the ground electrode before reaching the skin, allowing stable and intense plasma generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If atmospheric plasma is generated by direct contact between electrodes and skin, then plasma intensity and treatment effectiveness are improved, but electrical shock and safety risks occur
Solution Approach 1:
The patent introduces a dielectric barrier as an intermediary substance between the voltage electrode and the skin. This dielectric layer prevents direct electrical contact while allowing plasma generation and transfer, thus maintaining treatment effectiveness without electrical shock risk. The dielectric barrier acts as a mediator that enables plasma to be generated and transferred to the skin without direct electrode-skin contact.
2Productivity
If the distance between electrode and skin is reduced for better treatment effect, then plasma generation efficiency is improved, but electrical shock risk increases
Solution Approach 1:
The dielectric barrier serves as a mediator that enables the electrode to be positioned closer to the skin without direct contact. This intermediary layer maintains the electrical insulation necessary to prevent shock while allowing the plasma-generating electric field to effectively couple with the skin surface, thereby maintaining high plasma generation efficiency at reduced distances.
3Ease of operation
If anesthetic cream is applied to prevent electrical shock, then patient comfort is improved, but treatment time and complexity increase
Solution Approach 1:
The dielectric barrier is pre-applied to the skin surface before plasma treatment, creating a permanent protective layer that eliminates the need for temporary anesthetic applications. This preliminary protective action ensures patient comfort throughout the treatment process without requiring repeated applications or waiting periods, thereby reducing overall treatment time and procedural complexity.
4Reliability
If dielectric barrier is introduced to prevent electrical shock, then safety is improved, but device complexity increases
Solution Approach 1:
The patent employs thin film dielectric barriers that can be applied directly to the skin surface or integrated into the electrode structure. These thin film structures provide the necessary electrical insulation and safety protection without adding significant bulk or mechanical complexity to the device. The flexible nature of thin films allows them to conform to skin contours while maintaining their protective function.
