Solution Overview
Problem
Traditional electric dust collectors are difficult to miniaturize due to space requirements for power supply components and terminals, are not easily removable, and can hinder airflow and efficiency by being positioned near heat exchangers, leading to dew condensation and airflow obstruction.
Innovation Solution
The air cleaner is supported by the filter cleaning device and positioned apart from the heat exchanger, with a compact design that includes a charging unit and dust collecting unit with optimized electrode arrangements and terminal connections to minimize space and prevent airflow obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the electric dust collector is positioned near the heat exchanger, then the device structure is compact, but dew condensation occurs and airflow is obstructed
Solution Approach 1:
The air cleaner is extracted from the traditional position near the heat exchanger and relocated to be supported by the filter cleaning device. This spatial separation eliminates the harmful effects of dew condensation and airflow obstruction while maintaining a compact overall device structure through the integration with the filter cleaning device.
2Reliability
If power supply components and terminals are included in the electric dust collector, then the device is complete and functional, but the space required increases making miniaturization difficult
Solution Approach 1:
The power supply components and terminals are merged with the air cleaner assembly, which is itself integrated with the filter cleaning device. This consolidation approach maintains all necessary functional components while minimizing the overall space required through strategic integration rather than separate placement.
3Ease of operation
If the air cleaner is made removable for easy maintenance, then ease of operation improves, but electrical connection becomes more complex
Solution Approach 1:
The air cleaner is segmented as a removable module supported by the filter cleaning device, allowing easy removal for maintenance. The electrical connection is simplified through this modular design, where the air cleaner can be detached and reattached with straightforward electrical contacts, reducing the overall complexity of the connection system.
