Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrostatic purification technology is used, then particles can be removed and sterilized with low resistance, but the device produces high ozone and has poor safety
Solution Approach 1:
The patent changes the operating parameters by using a micro-electrostatic module with controlled high voltage output (3-15kV) instead of conventional electrostatic purifiers. This parameter change reduces ozone generation while maintaining particle removal efficiency through optimized electrode design and voltage control mechanisms.
Solution Approach 2:
The patent replaces the conventional electrostatic purification mechanism with a micro-electrostatic module that uses a filter element combined with high-voltage electrodes. This substitution maintains the electrostatic particle removal function while reducing harmful ozone production through improved electrical field distribution and controlled discharge.
2Reliability
If conventional electrostatic purification is used, then particles can be removed, but the service life is short and maintenance cost is high
Solution Approach 1:
The patent segments the electrostatic purification system into a filter element and separate high-voltage electrode components. This segmentation allows the filter element to be easily replaced while the electrodes, being washable and durable, continue to function for extended periods, thereby extending overall service life and reducing maintenance costs.
Solution Approach 2:
The patent enables easy replacement of the filter element (discarding the worn component) while recovering and reusing the high-voltage electrodes through washing and drying. This selective disposal approach extends the service life of durable components while replacing only the consumable filter element, reducing overall maintenance costs.
3Stability of the object's composition
If medium filtration technology is used, then the system is stable, but wind resistance is high and fan energy consumption is high
Solution Approach 1:
The patent replaces the mechanical fan-driven filtration system with an electrostatic field-based particle removal system. This substitution eliminates the need for high-power fans, significantly reducing energy consumption while maintaining system stability through controlled electrostatic fields that capture particles without requiring high-velocity air flow.
4Stability of the object's composition
If medium filtration technology is used, then the system is stable, but it breeds bacteria and viruses and produces odor
Solution Approach 1:
The patent converts the potential harm of electrical discharge into a beneficial sterilization effect. By controlling high-voltage electrodes to generate controlled electrical fields, the system not only removes particles but also sterilizes surfaces and air passages, eliminating bacteria and viruses while preventing odor generation through the same electrostatic mechanism.
