Solution Overview
Problem
Existing air ionization devices face challenges in maintaining long-term stability and controlling ozone production, especially during external interference events, which can lead to increased ozone levels exceeding limit values, and fail to effectively reduce bacteria, germs, and odors in room air.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If ionization intensity is increased to reduce bacteria, germs and odors, then air hygiene is improved, but ozone production increases and may exceed limit values
Solution Approach 1:
The patent employs multiple sensors (air quality sensor, ozone sensor, dust sensor) that continuously monitor air parameters and feed this information to a data processing system. The system dynamically adjusts the ionization intensity by controlling the voltage applied to ionization tubes, creating a closed-loop feedback control that maintains air hygiene while preventing ozone exceedance. This resolves the contradiction by making ionization intensity adaptive rather than fixed.
Solution Approach 2:
The ionization intensity is made dynamically adjustable through voltage control of multiple ionization tubes. The system can vary the operating parameters of each tube independently based on real-time air quality conditions, allowing optimization of disinfection effectiveness while controlling ozone generation. This dynamic capability enables the system to adapt to changing environmental conditions and maintain both air hygiene and ozone compliance.
2Object-affected harmful factors
If multiple sensors and control systems are added to control ozone and adjust ionization, then air quality control is improved, but device complexity increases
Solution Approach 1:
The data processing system serves multiple functions: it processes signals from various sensors (air quality, ozone, dust, air flow), controls multiple ionization tubes, and monitors system operation. By consolidating control logic into a single multi-functional unit, the patent reduces overall system complexity compared to having separate control circuits for each function. The ionization tubes themselves also serve dual purposes of air ionization and ozone generation, which is controlled through the same voltage adjustment mechanism.
3Productivity
If ionization tubes are operated at high voltage for effective ionization, then ionization effectiveness is improved, but long-term stability decreases due to increased ozone production
Solution Approach 1:
The system employs periodic monitoring and adjustment of ionization tube voltage based on sensor feedback. Rather than operating at constant high voltage, the system dynamically modulates voltage levels in response to air quality conditions, preventing sustained high-voltage operation that would lead to excessive ozone accumulation. This periodic adjustment maintains ionization effectiveness when needed while preventing long-term stability issues from continuous high-voltage operation.
