Solution Overview
Problem
Current plasma air purifiers produce positive and negative ions in lower concentrations, which limits their effectiveness in eliminating volatile organic compounds (VOCs), bacteria, and viruses, and they often suffer from issues like noise, power loss, and ozone buildup in small spaces.
Innovation Solution
A plasma air purifier using a boosted circuit design to generate high concentrations of positive and negative ions through a graphite point discharge, producing ozone integration strings that quickly dissipate, and an electric field of over 10 kV to create small ion clusters that oxidize pollutants and destroy bacteria and viruses, while being portable, quiet, and safe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If current plasma air purifiers produce ions in continuous and alternating fashion, then the device can operate continuously, but the ion concentration remains low which limits purification effectiveness
Solution Approach 1:
The patent employs periodic action by using alternating positive and negative ion emission cycles. The system switches between positive ion generation (for oxidizing pollutants) and negative ion generation (for capturing particles) in periodic intervals, maximizing both types of ion benefits while maintaining high overall ion concentration in the air
Solution Approach 2:
The system dynamically changes operational parameters by adjusting the voltage polarity and ion emission intensity based on detected air quality conditions. When VOCs are detected, positive ion emission is enhanced; when particulate matter is high, negative ion emission is increased, optimizing purification effectiveness across different pollution scenarios
2Quantity of substance
If plasma air purifiers use high energy to generate ions, then ion production increases, but power loss and energy consumption increase
Solution Approach 1:
The system maintains continuous useful action by using a capacitor to store energy during the non-emission phase and release it during ion generation. This continuous energy availability allows high ion concentration production without proportional increases in power loss, as the capacitor bridges energy gaps efficiently
Solution Approach 2:
The system changes voltage parameters dynamically, using high voltage only during brief ion emission pulses rather than continuously. This pulsed high-voltage approach generates sufficient ion concentration while dramatically reducing average power consumption and energy loss compared to continuous high-voltage operation
3Volume of moving object
If plasma air purifiers operate in small spaces, then portability is improved, but ozone buildup exceeds safe levels
Solution Approach 1:
The system uses periodic action with balanced positive and negative ion emission cycles. Negative ions naturally neutralize excess ozone through chemical reactions, and by ensuring equal time allocation to both ion types, the system prevents ozone accumulation even in confined small spaces while maintaining portability
Solution Approach 2:
The system converts the potentially harmful ozone byproduct into a beneficial neutralization process. Excess ozone that would normally accumulate is instead allowed to react with emitted negative ions, transforming it into harmless oxygen and water vapor, thereby eliminating the harmful effect while maintaining compact device operation
4Productivity
If plasma air purifiers produce high concentrations of ions, then purification effectiveness increases, but noise and static electricity discharge increase
Solution Approach 1:
The system introduces an intermediary corona discharge stage that gently pre-ionizes the air before the main ion emission. This intermediary process reduces the voltage gradient and prevents direct high-voltage arcing to ground, thereby eliminating noise and static discharge while maintaining high ion concentration production for effective purification

Function Achieved in This Case
The solution effectively reduces VOCs, bacteria, and viruses by producing high concentrations of ions that oxidize pollutants and destroy microbial organisms, maintaining safe ozone levels and avoiding noise and power issues, making it a potent and safe air purification system.
Implementation Method 1
The present invention generates a large number of small ion clusters while in an electric field that is preferably more than 10 kV. These small ions collide with oxygen molecules in the air to produce positive and negative oxygen ions.
Implementation Method 2
The present invention works under graphite point discharge, which is produced through independent tiny units of oxygen molecules, leading to the formation of ozone integration strings that quickly breakdown during the air purification process.
Implementation Method 3
Due to increased potency, positive oxygen ions oxidize and decompose methyl mercaptan, ammonia, hydrogen sulfide, and other pollutants in very short amounts of time and, as well as, stimulate the chemical reaction of volatile organic gases. After a series of reactions, carbon and water are ultimately generated.
Implementation Method 4
Moreover, the production of negative oxygen ions is essential as they may absorb suspended particles weighing dozens of times greater than itself and descent gravity. With this, suspended colloids (aerosols) are removed and the air is purified when the present invention is in use.
Implementation Method 5
Negative oxygen ions absorb suspended particles weighing dozens of times greater than itself and descent gravity.
Implementation Method 6
The ions are transformed into Hydroxide (OH) radicals and the oxidation that occurs is powerful, causing OH radicals to break down the protein surface by repeatedly stealing hydrogen (H) atoms from the organism's surface.
Implementation Method 7
The ions are transformed into Hydroxide (OH) radicals and the oxidation that occurs is powerful, causing OH radicals to break down the protein surface by repeatedly stealing hydrogen (H) atoms from the organism's surface.
