Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plasma generation devices generate ozone as a byproduct, which can harm the skin, and there is a need for an efficient method to remove ozone while ensuring sufficient plasma contact with the skin.
Innovation Solution
A plasma generation device design that separates plasma discharge and ozone intake paths, using a driving fan and filter to u-turn and remove ozone gas generated during plasma generation, with sensors to control fan speed based on ozone levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If air plasma is generated for skin care treatment, then plasma can effectively contact the skin to enhance skin care effects, but ozone gas is generated as a harmful byproduct that can damage the skin
Solution Approach 1:
The device divides the internal structure into separate functional zones: a plasma discharge port for plasma ejection and an ozone intake port for ozone inhalation. This segmentation allows plasma to contact the skin while ozone is directed away from the skin and into the device for removal.
Solution Approach 2:
The harmful ozone gas is extracted from the plasma generation process by introducing it into the device through the ozone intake port. The extracted ozone is then removed by the ozone removal unit, separating the harmful byproduct from the beneficial plasma treatment.
2Object-affected harmful factors
If a filter and fan are added to remove ozone, then ozone can be effectively removed from the device, but the device complexity increases
Solution Approach 1:
The ozone removal function is merged with the existing device structure by integrating the fan and filter into the housing. The intake port, exhaust port, fan, and filter form a unified ozone removal system that works together to eliminate ozone without requiring completely separate components.
Solution Approach 2:
The device removes its own harmful byproduct (ozone) through the integrated ozone removal unit. The fan draws ozone into the device and the filter removes it, allowing the device to self-regulate and eliminate its own harmful emissions without external intervention.
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
Effectively prevents ozone from directly contacting the skin by u-turning and filtering it, minimizing skin damage and ensuring effective plasma application.
Implementation Method 1
a plasma generation pad located inside the plasma tip and generating plasma toward an inner surface of the plasma tip
Implementation Method 2
ozone is removed from the ozone gas inhaled into the ozone intake passage by a rotational force of the driving fan
Implementation Method 3
ozone is removed from the ozone gas inhaled into the ozone intake passage by a rotational force of the driving fan through the filter

AI summary
The present disclosure discloses a plasma generation device. The device of the present disclosure includes a plasma generation pad that generates plasma and is configured such that one side based on the plasma generation pad is used as a plasma movement passage, and the other side is used as an ozone intake passage. In addition, plasma generated by the plasma generation pad is supplied to the skin through the discharge port by vertically changing a direction in the plasma movement passage, and ozone gas generated by the plasma is u-turned at the outside to be inhaled into the ozone intake passage. Ozone gas inhaled into the ozone intake passage is removed while passing through the filter, and only ozone-removed gas is discharged through the purification exhaust port.
