Cylindrical Filter Device with Elastic Flange for Pipe Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter devices for liquid flow channels in pipes, such as those in radiators, often have a reduced effective filtering area and fail to completely divide the pipe, leading to inadequate filtration.
Innovation Solution
A filter device with a cylindrical main body and flange portions that elastically deform to create a liquid-tight division within the pipe, ensuring a large filtering area by using filter material effectively across the entire flow channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter device is inserted into a pipe to filter liquid, then the filtering function is provided, but the effective filtering area is reduced
Solution Approach 1:
The filter device is divided into a main body portion and a flange portion. The flange portion segments the pipe interior into an upstream side and a downstream side, creating a liquid-tight division. This segmentation allows the filter material in the main body to effectively filter liquid while maintaining a large filtering area through the flange's structural extension.
Solution Approach 2:
The flange portion extends radially outward from the main body, adding a dimensional extension that creates a liquid-tight seal without reducing the axial filtering area. This dimensional change allows the filter to maintain effectiveness while preserving the filtering area through the flange's radial projection.
2Reliability
If a filter device is inserted into a pipe, then filtering is provided, but the pipe is not completely divided, reducing filtration effectiveness
Solution Approach 1:
The flange portion is designed to elastically deform during insertion and then maintain a flexible, liquid-tight seal against the pipe inner surface. This elastic deformation allows the flange to conform to the pipe interior, creating a complete and stable division that prevents liquid bypassing the filter material.
Solution Approach 2:
The flange portion is designed as a disposable sealing element that deforms elastically during insertion and then remains as a permanent liquid-tight barrier. This simple, single-use sealing structure effectively divides the pipe without requiring complex mechanical fastening systems.
3Ease of operation
If flange portion is made to deform elastically for insertion, then easy installation is achieved, but the filter device may slip out of the pipe
Solution Approach 1:
The flange portion transitions from a dynamic, elastic deformation state during insertion to a static, firm attachment state after installation. The elastic deformation allows easy insertion, while the subsequent firm attachment to the pipe inner surface prevents slipping, achieving both ease of operation and positioning stability.
Solution Approach 2:
The flange portion is pre-designed with elastic deformation capability to facilitate easy insertion during installation. This preliminary design feature allows the flange to deform and expand during insertion, then maintain its position firmly against the pipe interior, preventing subsequent slipping.

AI summary
A filter device includes a main body portion having a cylinder shape, and the main body portion is inserted along a center axis of the pipe. One end portion of the main body portion structuring a filter device is blocked. At least one portion of a flange portion is provided between both end portions of the cylinder, and the flange portion divides a space inside the pipe in a liquid-tight state by elastically deforming and by being attached firmly to an inner surface of the pipe. A first passing portion of the liquid is provided in a cylinder side portion between the one end portion of the cylinder and the flange portion, and a second passing portion of the liquid is provided on a side close to the other end portion of the cylinder than the flange portion.
