Nested transparent case structure for fluid pressure device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid pressure devices face challenges in reliably and easily connecting their case structures to the body while ensuring the interior can be visually inspected and maintaining durability, especially in environments where gases or solvents may be present.
Innovation Solution
A case structure formed as a bottomed cylinder with a light-permeable transparent resin material, featuring a first and second case portion where the second portion is disposed inside the first, and engagement members on the outer surface that connect with the body's installation hole, allowing for easy assembly and visibility of the interior without exposing the second case portion to external contaminants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the case is made transparent for visibility, then the interior can be easily observed, but the case may be more susceptible to external contaminants adhering to it
Solution Approach 1:
The case is divided into an outer case and an inner case, creating separate functional zones. The outer case handles external interactions while the inner case maintains the clean internal environment, resolving the contradiction between visibility and contaminant resistance.
Solution Approach 2:
The inner case is nested within the outer case, with the inner case being the transparent visible portion and the outer case providing protective coverage. This nested structure allows the internal components to be observed through the inner case while the outer case shields against external contaminants.
2Device complexity
If the case is made as a single integrated structure, then the structure is simple, but the durability against external contaminants is reduced
Solution Approach 1:
The case is segmented into outer and inner cases with distinct functions. The outer case provides protective durability while the inner case maintains visibility, achieving both structural simplicity and enhanced reliability without significant complexity increase.
Solution Approach 2:
Different portions of the case have different qualities - the outer case is designed for protective durability while the inner case is designed for transparency and visibility. This local differentiation resolves the contradiction between simplicity and durability.
3Loss of information
If all case portions are exposed to the exterior for visibility, then the entire interior is accessible for observation, but the durability is reduced due to exposure to external contaminants
Solution Approach 1:
The case is segmented into outer and inner cases where only the necessary inner case portions are exposed for visibility, while the outer case remains protected. This segmentation allows selective exposure that maintains both visibility and durability.
Solution Approach 2:
The inner case is nested within the outer case, allowing the inner case to be transparent for visibility while the outer case provides protective coverage. This nested arrangement enables the interior to be observed without the entire case structure being exposed to contaminants.

AI summary
In a case structure for a fluid pressure device, a filter that constitutes part of a fluid pressure unit is equipped with a first body, a case unit connected to a lower portion of the first body, and a filter unit 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 inserted into the interior of the outer case. Additionally, by insertion of the case unit into an installation hole that opens on a lower portion of the first body and rotating the case unit, projections and retaining walls provided on an outer circumferential surface of the case unit engage with support members provided in the installation hole, thus placing the case unit in a connected state.
