Solution Overview
Problem
Existing electrostatic filter structures face challenges in providing a robust and efficient supporting structure for filter plates while ensuring proper voltage connection and minimizing accidental coupling between plates of different potentials, especially in designs without a frame structure.
Innovation Solution
A rack with notches for supporting filter plates and a slot for adhesive attachment, which can be made of conductive or non-conductive material, acting as both a supporting and voltage supply structure, with electrical connectors to manage different electric potentials and prevent accidental coupling by maintaining a distance between plates and racks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a frameless filter structure is used, then the filter design is simplified and manufacturing cost is reduced, but the supporting structure for filter plates becomes less stable and more difficult to manufacture
Solution Approach 1:
The filter structure is divided into modular rack units, each independently supporting specific filter plates. This segmentation allows for simplified manufacturing of individual racks while maintaining overall structural stability through modular assembly, resolving the contradiction between ease of manufacture and structural reliability.
Solution Approach 2:
The rack structure serves multiple functions: it provides mechanical support for filter plates, establishes electrical connections between plates, and maintains proper spacing. This multi-functionality eliminates the need for separate frame structures, simplifying manufacturing while ensuring reliability through integrated design.
2Reliability
If conductive material is used for the rack, then voltage connection between plates is improved, but accidental coupling between plates of different potentials increases
Solution Approach 1:
The rack is designed with differentiated electrical properties at different locations: conductive sections for reliable voltage connection at specific points, and insulating sections for spacing and isolation. This local quality variation ensures proper electrical connectivity where needed while preventing accidental coupling between plates of different potentials.
Solution Approach 2:
Insulating sections of the rack act as intermediaries between conductive sections, providing physical support and spacing while blocking electrical coupling. This mediator approach allows the rack to simultaneously provide electrical connection where required and electrical isolation where needed, resolving the contradiction between connection reliability and coupling prevention.
3Area of stationary object
If plates are placed close together to maximize filtering area, then space utilization is improved, but the risk of accidental coupling between plates increases
Solution Approach 1:
The rack structure introduces a third dimension (vertical spacing) to separate plates that are close in the horizontal plane. By providing support from below and maintaining vertical clearance, the rack enables high plate density while preventing contact and accidental coupling, thus maximizing filtering area without increasing coupling risk.
4Strength
If adhesive is applied extensively to attach plates to racks, then plate attachment strength is improved, but the complexity of assembly and cleaning increases
Solution Approach 1:
Adhesive application features are pre-integrated into the rack structure during manufacturing, with recesses and channels positioned to optimize adhesive distribution. This preliminary action ensures strong plate attachment while simplifying assembly, as the adhesive geometry is already prepared rather than requiring complex assembly procedures.
