Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If wire-plate type ESP is used for industrial air purification, then fine particles removal efficiency is improved, but volume and mobility deteriorate
Solution Approach 1:
The ESP is divided into multiple independent modules, each containing a discharge electrode and collection electrode pair. These modules can be arranged in series within a compact housing, enabling high particle removal efficiency through multiple stages while maintaining a small overall volume suitable for portable use.
2Manufacturing precision
If wire-plate type ESP is used for industrial air purification, then fine particles removal efficiency is improved, but ease of maintenance deteriorates
Solution Approach 1:
Each module with discharge and collection electrodes is designed as an independent unit that can be easily accessed and cleaned. The modular structure allows users to remove and clean individual electrode pairs without disassembling the entire device, significantly improving ease of maintenance while preserving high removal efficiency.
3Reliability
If conventional electrostatic air cleaner design is used, then particle collection function is achieved, but device complexity and size increase
Solution Approach 1:
Multiple functional components are integrated into a compact unified structure. The discharge electrodes, collection electrodes, fan, and housing are combined into a single portable unit with streamlined airflow path, reducing device complexity while maintaining effective particle collection function.

Function Achieved in This Case
This design enables efficient particle removal from the air, making the air cleaner compact, portable, and easy to manufacture and maintain, while allowing for scalability and versatility in unit combinations.
Implementation Method 1
the corona discharged module is used for producing point discharges with first polarity... Particles in the air stream would be electrically charged by an electric field of the corona discharged module
Implementation Method 2
The charged particles are then attracted and thus adhere to collection plates so as to purify the air

AI summary
An electrostatic air cleaner comprises a main body, a corona discharged module, a collector module and a fan. The main body has an airflow passage for disposing the corona discharged module, the collector module and the fan. The fan is used for drawing an air stream into the airflow passage. The corona discharged module is used for discharging particles in the air stream. The charged particles are then captured by the collector module.
