Rotary Filter Container Attachment Mechanism for Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In filtration systems, the attachment and detachment of filter containers to manifolds with constant distance between flow path ends result in high friction, making attachment and detachment difficult, leading to sealant abrasion and reduced durability due to dust generation and adhesion issues.
Innovation Solution
A filter attachment and detachment apparatus featuring a first mounting protrusion with a rotation element and a holding part that allows for easy attachment and detachment through a combination of translation and rotation operations, reducing sealant abrasion by using inclined surfaces and notches to secure the protrusion within the apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter container is attached to a manifold with constant distance between flow path ends, then the flow path is completed and filtration function is achieved, but high friction occurs making attachment and detachment difficult
Solution Approach 1:
The invention introduces a rotating attachment mechanism where the filter container can be rotated to attach to and detach from the manifold. This dynamic attachment method transforms the static constant-distance connection into a rotational motion-based connection, reducing friction during attachment/detachment operations while maintaining sealing efficiency through the rotation element's design.
Solution Approach 2:
The invention adds a rotational dimension to the attachment process. Instead of linear movement along a single axis, the filter container attaches by rotating around an axis, introducing a new dimensional approach to the connection mechanism. This rotational dimension allows the sealing surfaces to engage more easily while maintaining the required sealing pressure.
2Reliability
If high adhesion is secured for the joining portion of fluid inlet/outlet, then sealing efficiency is improved, but friction at the joining portion becomes large making attachment and detachment difficult
Solution Approach 1:
The rotating attachment mechanism allows the sealing surfaces to engage through rotation rather than linear pressing. This dynamic engagement reduces the friction force required for attachment while maintaining adequate adhesion for sealing. The rotation element's design ensures that sealing pressure is applied effectively during the rotational motion without creating excessive friction resistance.
3Ease of operation
If pivot operation is used to attach filter container, then attachment is achieved, but rubbing distance of sealing member is long causing abrasion and dust generation
Solution Approach 1:
The invention changes the attachment motion from linear pivot operation to rotational movement. By introducing rotational motion around an axis, the sealing member's rubbing distance is significantly reduced compared to linear pivot operations. The rotation element guides the sealing surfaces to engage in a compact rotational path, minimizing abrasion and dust generation.
4Device complexity
If translation operation from perpendicular direction is used to attach filter container, then attachment without pivot operation is achieved, but the distance between flow path ends cannot be maintained constant
Solution Approach 1:
The rotating attachment mechanism provides a dynamic solution that maintains the constant distance between flow path ends while enabling simple attachment. The rotation element is designed to accommodate the fixed distance requirement, allowing the filter container to rotate into position without altering the critical distance between flow paths. This maintains the simplicity of the attachment mechanism while preserving the geometric constraint.

AI summary
A filter attachment and detachment apparatus removably attaching a filter container containing a filter, as a part of a filtration apparatus that filters fluid with the filter, includes a first mounting protrusion at one end of the filter container to protrude from the filter container, the first mounting protrusion including a flow path in fluid communication with the filter inside the filter container, a rotation element to which a first flow path for the fluid is connected, the rotation element including an opening groove configured to receive the first mounting protrusion, and a first mounting protrusion holding part configured to rotatably hold the rotation element. The first mounting protrusion holding part includes an inner periphery surface and a notch communicating with an outer side of the inner periphery surface, where in a state where the first mounting protrusion is inserted into the opening groove through the notch, by rotating the rotation element, the first mounting protrusion is bound between the inner periphery surface of the first mounting protrusion holding part and the rotation element.
