Filter Vessel Attachment Guide Member Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In filtration systems, attachment/detachment of filter vessels through translation movement results in high friction at joints, making tasks difficult and leading to seal material attrition and reduced durability due to unchanged conduit end distances and high adhesion requirements.
Innovation Solution
A filter vessel attachment/detachment apparatus with a clamping portion and guide member that rotates to gradually clamp a flange, reducing initial friction during attachment and maintaining high adhesion, allowing for easy and secure attachment/detachment through translation movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter vessel is attached through translation movement with high adhesion at joints, then the sealing performance is improved, but the friction becomes large making attachment/detachment difficult
Solution Approach 1:
The guide member is designed to rotate about a second axis that is offset from the first axis (the translation movement axis). This rotational degree of freedom allows the system to dynamically adjust the clamping force distribution, reducing peak friction forces while maintaining sealing contact between the flange and clamping portion.
Solution Approach 2:
The guide member acts as an intermediary mechanism between the translation movement and the final clamping action. By introducing this intermediate rotational element, the system can achieve both easy attachment (through rotation) and secure sealing (through controlled clamping) without direct high-friction contact.
2Device complexity
If the filter vessel is attached through translation movement, then the structure is simplified, but the seal material attrition increases due to high friction
Solution Approach 1:
The rotating guide member introduces dynamic motion to the attachment process, converting a static high-friction sliding contact into a dynamic rolling-like interaction. This reduces the wear on seal materials while maintaining the relatively simple overall structure of the attachment mechanism.
3Productivity
If the guide member rotates about an axis close to the first axis, then the clamping action is direct, but the friction force remains high throughout the motion
Solution Approach 1:
The second axis is positioned at a predetermined distance from the first axis, introducing a spatial dimension offset. This offset creates a lever arm effect where the rotation can generate clamping force more efficiently, reducing the direct friction resistance while maintaining clamping effectiveness.

AI summary
The filter vessel attachment/detachment apparatus includes a first conduit end, wherein a first conduit for the fluid to flow through is coupled to the first conduit end, and the first conduit end has a clamping portion capable of clamping the flange of the filter vessel; a contact surface capable of strongly contacting to the inlet or the outlet of the filter vessel; and a guide member capable of, for a direction from the first conduit toward the inlet or the outlet, rotating about a second axis separated from a first axis by a predetermined distance, the first axis being from the first conduit toward the inlet, the guide member having a holding portion capable of holding the inlet or the outlet.
