Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical dust collecting apparatuses face inefficiencies in dust collection due to non-uniform electrification, material wastage, and increased pressure loss, primarily because the electrification holes in the electrification plate are cut, leading to uneven electrification and blockage of air flow.
Innovation Solution
An electrification device with an electrification electrode where electrification pins and an electrode rod are formed integrally, and the electrification holes have a shape with overlapping circles, allowing for uniform electrification and improved mounting properties, reducing material waste and pressure loss by using a single metal plate for the electrode and optimizing pin placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If electrification holes are cut in the electrification plate, then pins can be positioned to electrify dust particles, but electrification becomes non-uniform depending on cut state and material is wasted
Solution Approach 1:
The patent merges the electrification plate and pins into a single integrated electrode structure where the plate itself forms the electrification holes without separate cutting operations. This integration eliminates material waste from cutting operations and ensures uniform electrification by precisely defining hole geometry during forming rather than through post-manufacturing cutting.
2Adaptability or versatility
If electrification holes are formed by cutting through the electrification plate, then pins can be inserted at various positions, but pressure loss increases due to blocked regions
Solution Approach 1:
The integrated electrode structure combines the plate and hole formation into a single manufacturing step, allowing optimization of both airflow characteristics and pin positioning simultaneously. The plate thickness and hole geometry are designed together to minimize flow resistance while maintaining pin placement flexibility.
3Ease of manufacture
If electrification holes are formed by cutting, then the structure can be simple to manufacture, but manufacturing precision decreases due to cut state variations
Solution Approach 1:
The electrification holes are formed as integral features of the plate during the plate forming process itself, before any assembly or pin insertion occurs. This preliminary formation of precise hole geometry eliminates variability introduced by subsequent cutting operations while maintaining manufacturing efficiency through a single-forming process.
