Filter Apparatus With Detachable Case For Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filter apparatuses for removing dust and particulates from pressure fluids are cumbersome to maintain, especially when installed in high or low locations, due to the complex detachment and reattachment processes of the filter element, which is connected to the main body and requires disassembly of the case.
Innovation Solution
A filter apparatus with a detachable case that accommodates a filter unit, featuring a connecting mechanism to regulate axial displacement, allowing easy attachment and detachment of the filter unit, simplifying maintenance operations regardless of the installation location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filter element is connected to the main body, then the filter apparatus maintains structural stability, but the filter element cannot be easily removed for maintenance
Solution Approach 1:
The filter apparatus is divided into three main segments: the main body, the case, and the filter element. The case acts as an intermediate container that holds the filter element and can be detached from the main body. This segmentation allows the filter element to be accessed and removed by simply detaching the case, without needing to disconnect the filter element directly from the main body, thus simplifying the maintenance process while maintaining structural integrity during operation.
2Ease of operation
If the case is provided to cover the filter element, then the filter apparatus has a compact structure, but the case requires significant axial movement for detachment
Solution Approach 1:
The case is designed as a separate segment with a detachable connection to the main body through threading mechanisms. This segmentation allows the case to be detached with minimal axial movement, as the threaded connection can be undone by simply rotating the case rather than pulling it axially over a long distance. The filter element remains contained within the case during this process.
Solution Approach 2:
The connection between the case and main body incorporates dynamic elements such as threaded fasteners that allow for easy attachment and detachment through rotational motion. This dynamic connection mechanism reduces the axial movement required for case detachment compared to a rigid fixed connection, making maintenance operations more convenient while maintaining a compact structure during normal operation.
3Ease of operation
If the filter element projects from the main body, then the filter element is accessible, but the case must move significantly to cover it
Solution Approach 1:
The filter element is housed within the case as a separate segment, which itself is detachable from the main body. This nested segmentation structure allows the filter element to be accessed by simply removing the case from the main body, without requiring the filter element to protrude significantly. The case provides a compact enclosure that maintains accessibility while reducing the overall complexity of attachment and coverage operations.

AI summary
A filter apparatus is equipped with a first body, a case unit connected to a lower part of the first body, and a filter unit, which is accommodated in the interior of the case unit. The case unit is made up from an outer case, which is formed as a bottomed cylinder from a light-permeable transparent material, and an inner case that is inserted into the interior of the outer case. The case unit is inserted into an installation hole that opens on the lower part of the first body, and by rotation thereof, projections and retaining walls provided on an outer circumferential surface of the case unit are made to engage with support members provided in the installation hole, to thereby result in a connected state.
