Hollow Cylindrical Filter Structure for Multidirectional Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hollow cylindrical filters formed by winding metal wire rods in a spiral manner lack the ability to efficiently remove foreign substances in directions other than the radial direction due to their fixed cross-sectional shape, limiting their filtration efficiency and functionality.
Innovation Solution
The filter is designed by winding metal wire rods in a spiral and multilayered manner with inclined layers that intersect, forming communication paths in the axial, radial, and peripheral directions, and incorporating recesses in the metal wire rods to create overlapping spaces that allow fluid to pass through in multiple directions, enhancing filtration efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If metal wire rods with fixed cross-sectional shape are used, then manufacturing is simple, but filtration efficiency in multiple directions is poor
Solution Approach 1:
The wire rod cross-section is segmented into multiple regions including flat surfaces and inclined surfaces, allowing fluid to pass through in multiple directions (radial, axial, and peripheral) rather than a single direction, thereby improving filtration efficiency while maintaining a relatively simple overall structure
Solution Approach 2:
Different regions of the wire rod cross-section are given different properties: flat surfaces provide stable support and easy manufacturing, while inclined surfaces guide fluid flow in specific directions. This local differentiation enables multi-directional filtration without significantly complicating the overall wire rod structure
2Productivity
If wire rod layers are wound in parallel directions, then winding process is simple, but communication paths in overlapping directions are limited
Solution Approach 1:
Adjacent wire rod layers are wound at different angles relative to the axial direction, creating an asymmetric winding pattern. This asymmetry ensures that wire rods from adjacent layers intersect and form communication paths in overlapping directions, enabling fluid to pass through the filter in multiple directions simultaneously, thereby improving filtration efficiency without requiring complex winding equipment
3Manufacturing precision
If communication paths are limited to radial direction, then filter structure is simple, but foreign substance removal capability is insufficient
Solution Approach 1:
The filter structure transitions from single-direction (radial) communication paths to multi-directional communication paths by incorporating inclined surfaces on wire rod cross-sections. This dimensional expansion allows fluid to pass through in radial, axial, and peripheral directions simultaneously, significantly improving foreign substance removal capability without requiring complex internal passages or chambers

AI summary
Embodiments of the present invention provide a hollow cylindrical filter for removing efficiently foreign substances from fluids. This is performed by forming complicated passages including an axial direction and a radial direction in the filter. The hollow cylindrical filter is formed by winding a metal wire rod in a spiral and multilayered manner. The metal wire rod includes a recess formed throughout the entire length in a longitudinal direction, or recesses repeated along said longitudinal direction. Some wire rod layers extend in an axial direction of the hollow cylindrical filter while the adjacent wire rod layers extend in an intersecting direction, thereby forming a plurality of communication paths for communicating between the overlapping wire rod layers. Additionally, a space is formed between the recess of one wire rod layer and another adjacent wire rod layer, allowing the plurality of communication paths to communicate with each other.
