Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ordinary air purifiers with air filtration function are used, then basic air filtration is achieved, but they cannot effectively neutralize airborne viruses and bacteria
Solution Approach 1:
The patent changes the purification mechanism from physical filtration to electrostatic ionization. By introducing positive and negative ion generators that produce high-voltage electric fields, the system transforms airborne pathogens through ionization rather than merely filtering them, fundamentally changing the purification parameter from mechanical capture to electrostatic neutralization
Solution Approach 2:
The ion generators produce strong electric fields that create highly reactive oxygen ions. These oxygen ions act as strong oxidizing agents that rapidly neutralize and destroy the structure of viruses and bacteria, providing accelerated oxidation-based pathogen elimination rather than slow filtration processes
2Reliability
If positive and negative ion generators are introduced for air purification, then effective virus and bacteria neutralization is achieved, but energy consumption increases
Solution Approach 1:
The system utilizes the existing airflow from the air conditioner's own operation to drive the ion generators. The air flow itself becomes the power source, eliminating the need for separate high-voltage power supplies. The air conditioner's operational airflow automatically activates and powers the ionization process, making the system self-sufficient
Solution Approach 2:
The patent merges the air circulation function with the ion generation function. The airflow system that already exists for cooling/heating is combined with the ion generator to provide dual functionality. This integration eliminates the need for separate power consumption for ionization, as the same airflow serves both purposes
3Loss of energy
If wind power generation is used to power the ion generator, then zero energy consumption is achieved, but device complexity increases
Solution Approach 1:
The air conditioner's airflow system serves multiple functions simultaneously: it provides cooling/heating, drives the ion generator through airflow-induced rotation, and powers the entire ionization process. This multi-functionality eliminates the need for separate power sources and reduces overall system complexity despite adding ion generation capability
Solution Approach 2:
The airflow acts as an intermediary that transfers energy from the air conditioner's operational flow to the ion generator. The moving air itself becomes the medium that converts kinetic energy into electrical energy to power the ionization process, eliminating the need for complex external power supply systems

Implementation Method 2
ion generator, secured to the housing;... low voltage is raised to positive high voltage and negative high voltage through a booster circuit, and air is ionized under the action of the positive high voltage electric field and the negative high voltage electric field, thereby generating a large number of positive and negative ions
Implementation Method 3
The positive and negative oxygen ions emitted into the air attract each other in pairs. During the process of mutual attraction, the positive and negative oxygen ions meet with the airborne bacteria in the air. Enormous energy is released at the moment when the positive and negative charges are neutralized
