Solution Overview
Problem
Existing hand-held devices for creating cold plasmas face challenges such as electrode degradation and overheating due to the use of negative electrode configurations, making it difficult to achieve a dense cold plasma electron population.
Innovation Solution
A hand-held device that generates atmospheric pressure cold plasma without using a negative electrode configuration, employing an rf tuning network, high-voltage coils, and capacitors to produce a 150-kV dielectric rf signal, which is transferred through a protected cable to an electrode system comprising multiple parallel plates and a magnetic compression chamber to create multiple-frequency cold plasma.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a negative electrode configuration is used to create cold plasma, then plasma generation is achieved, but electrode degradation and overheating occur
Solution Approach 1:
The patent removes the negative electrode from the plasma generation system, retaining only the positive electrode. This extraction of the problematic negative electrode eliminates the source of degradation and overheating while maintaining plasma generation capability through the positive electrode alone
Solution Approach 2:
Instead of using the conventional positive-to-negative electrode configuration, the patent inverts the approach by using only a positive electrode with ground reference, thereby eliminating the harmful negative electrode effects while maintaining plasma generation
2Reliability
If continuous operation is performed to maintain plasma, then plasma density is maintained, but electrode degradation accelerates
Solution Approach 1:
By removing the negative electrode that degrades during continuous operation, the system can maintain continuous plasma generation without the accumulating damage that would otherwise limit electrode service life
Solution Approach 2:
The positive electrode design with ground reference allows the system to self-regulate during continuous operation, avoiding the progressive degradation that occurs in conventional dual-electrode systems

AI summary
A method for generating atmospheric pressure cold plasma inside a hand-held unit discharges cold plasma with simultaneously different rf wavelengths and their harmonics. The unit includes an rf tuning network that is powered by a low-voltage power supply connected to a series of high-voltage coils and capacitors. The rf energy signal is transferred to a primary containment chamber and dispersed through an electrode plate network of various sizes and thicknesses to create multiple frequencies. Helium gas is introduced into the first primary containment chamber, where electron separation is initiated. The energized gas flows into a secondary magnetic compression chamber, where a balanced frequency network grid with capacitance creates the final electron separation, which is inverted magnetically and exits through an orifice with a nozzle. The cold plasma thus generated has been shown to be capable of accelerating a healing process in flesh wounds on animal laboratory specimens.
