Plasma Actuator Reactive Oxygen Flow for Deep Fabric Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface treatment apparatuses using ultraviolet rays and ozone are ineffective in treating the internal spaces of objects like cloth or non-woven fabrics, as reactive oxygen generated is unstable and unable to penetrate deeply.
Innovation Solution
A treatment apparatus comprising a plasma actuator and an ozone decomposing device that generates and supplies reactive oxygen, allowing it to be conveyed and applied to both the surface and internal spaces of objects, using a dielectric barrier discharge to create an induced flow containing ozone, which is then decomposed into reactive oxygen and directed internally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ultraviolet rays and ozone are used for surface treatment, then surface sterilization and treatment effect are improved, but treatment penetration to internal spaces is insufficient
Solution Approach 1:
The patent changes the physical state and delivery method of reactive oxygen from static ozone gas to dynamic plasma-induced flow. By applying dielectric barrier discharge, the system generates a controlled flow of reactive oxygen species that can be directed toward the object surface, enhancing both surface treatment reliability and internal penetration capability through the flow's momentum and concentration.
Solution Approach 2:
The invention utilizes plasma-induced flow, a pneumatic phenomenon, to deliver reactive oxygen to the object. The dielectric barrier discharge generates a measurable flow that can penetrate into the internal spaces of objects like cloth or non-woven fabrics, overcoming the limitation of static ozone treatment and enabling deep penetration while maintaining surface treatment effectiveness.
2Reliability
If ozone is used for treatment, then oxidative decomposition and sterilization are achieved, but reactive oxygen stability is insufficient for deep penetration
Solution Approach 1:
The patent transitions from static ozone gas to dynamic plasma-induced flow. The dielectric barrier discharge continuously generates reactive oxygen species in a controlled flow, maintaining their reactive state longer and enabling them to penetrate deeper into objects while preserving sterilization effectiveness. The dynamic nature of the flow keeps reactive oxygen molecules in a stable, active state throughout the treatment process.
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 apparatus effectively treats both the surface and internal spaces of objects by maintaining the reactive state of oxygen longer, ensuring deeper penetration and improved treatment efficacy.
Implementation Method 1
when a voltage is applied between the first electrode and the second electrode, the plasma actuator generates a dielectric barrier discharge from the first electrode to the second electrode and cause an induced flow containing ozone to be blown out from the first electrode
Implementation Method 2
the ozone decomposing device generates reactive oxygen in the induced flow by decomposing the ozone contained in the induced flow
