Solution Overview
Problem
Current electrostatic dust collection devices face issues such as deformation or breakage of plastic-plate micro-electrostatic field devices due to environmental changes, leading to safety hazards and reduced efficiency, while metal-plate devices struggle with inconsistent spacing and increased size, manufacturing costs, and limited application scenarios due to the need for safety distances.
Innovation Solution
The design includes a support column and positioning assembly that supports metal plates of different polarities, allowing precise spacing and reducing the distance between adjacent plates, enhancing processing precision and efficiency, and incorporating a protective frame to prevent short-circuiting and deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If plastic-plate micro-electrostatic field dust collection devices are used, then manufacturing cost is reduced, but the substrate deforms or breaks under environmental changes leading to short-circuit arcing and safety hazards
Solution Approach 1:
The patent uses disposable aluminum foil instead of durable but expensive metal plates or plastic substrates. The aluminum foil is intentionally designed to be replaceable rather than permanent, allowing cost-effective replacement when it becomes contaminated or deformed, thus resolving the contradiction between low manufacturing cost and reliability.
Solution Approach 2:
The patent changes the material parameter from plastic substrate to aluminum foil, and adjusts the spacing parameter to 1-3mm. This parameter change allows the use of cheaper material while maintaining reliability through precise spacing control and disposable nature.
2Reliability
If metal-plate micro-electrostatic field dust collection devices are used, then reliability is improved, but the device size increases and occupies more space
Solution Approach 1:
The patent changes the plate material to aluminum foil and reduces the spacing parameter to 1-3mm, which is smaller than conventional metal-plate devices. This allows maintaining reliability through consistent spacing while significantly reducing device size and volume.
Solution Approach 2:
The patent uses thin aluminum foil instead of rigid metal plates. The thin film structure allows for closer spacing between plates while maintaining structural integrity, thus reducing device size while preserving reliability through consistent spacing.
3Reliability
If sufficient safety distance of 5mm to 10mm is maintained between adjacent parallel conductive plates, then short-circuit arcing is avoided, but purification efficiency decreases
Solution Approach 1:
The patent changes the spacing parameter from 5-10mm to 1-3mm by using aluminum foil instead of metal plates. This parameter change allows much closer spacing without short-circuit arcing, thereby maintaining high purification efficiency while ensuring reliability.
Solution Approach 2:
The disposable aluminum foil can be replaced when contaminated, allowing operation at optimal close spacing (1-3mm) for high efficiency. The replaceable nature ensures reliability is maintained even at reduced spacing where conventional permanent plates would risk arcing.
4Productivity
If the distance between adjacent parallel conductive plates is reduced, then purification efficiency is improved, but short-circuit arcing risk increases
Solution Approach 1:
The patent changes the material parameter to aluminum foil and optimizes the spacing parameter to 1-3mm. This combination allows reduced spacing for high purification efficiency while the disposable nature and material properties of aluminum foil prevent short-circuit arcing, thus resolving the contradiction.
Solution Approach 2:
The disposable aluminum foil allows operation at optimal close spacing (1-3mm) for high efficiency. When the foil becomes contaminated or shows signs of arcing, it can be replaced, thus maintaining high efficiency operation without permanent safety risks.
