Segmented Tubular Filter for Easy Post-Use Observation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tubular filtration filters capture filtration objects inside, making it difficult to observe them post-filtration, and there is a need for a filter that can be easily cut after use without being broken by fluid forces during filtration.
Innovation Solution
A filtration filter with a tubular shape featuring a continuous and non-continuous portion, where the non-continuous portion is designed to be easily cut by an external force while maintaining strength to withstand filtration forces, using a filter base with a square grid array of through holes and shifting the non-continuous portion to concentrate stress for easy cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filter is made as a complete tubular structure, then it maintains mechanical strength to withstand filtration forces, but it becomes difficult to cut after use for observation
Solution Approach 1:
The filter base is divided into a continuous portion and a non-continuous portion. The non-continuous portion has through holes that are shifted relative to the continuous portion, creating a segmented structure that concentrates stress and enables easy cutting while maintaining overall structural integrity during filtration.
2Ease of operation
If the filter base is made continuous, then it maintains structural integrity during filtration, but it cannot be easily cut for post-filtration observation
Solution Approach 1:
The filter base is segmented into continuous and non-continuous portions with shifted through holes, creating weak points for cutting while preserving structural integrity in the continuous portions that withstand filtration forces.
Solution Approach 2:
Different portions of the filter base have different properties: the continuous portion maintains structural integrity and strength, while the non-continuous portion with shifted through holes provides easy cutting capability. This local differentiation resolves the contradiction between overall integrity and localized cutability.

AI summary
A filtration filter having a planar shape and including a filter base that defines a plurality of through holes arranged in a square grid array. The filter base includes a continuous portion having a first set of through holes of the plurality of through holes, and a non-continuous portion having a second set of through holes of the plurality of through holes. The continuous portion extends in a first direction and extends in a second direction along at least a first portion of the filtration filter orthogonal to the first direction. The non-continuous portion has the second set of through holes shifted relative to the first set of through holes of the continuous portion and extends in the first direction.
