Membrane Filters TRIZ Cases

An eccentric closure seals the filter housing drainage opening axially, simplifying installation while reliably opening the drain when the filter element is removed.

Microfibrillated cellulose fibers strengthen nonwoven filtration media and improve efficiency while maintaining porosity without added resin.

An asymmetric seal bead keeps a tower-press diaphragm sealed during filtration while releasing overpressure during opening.

Radial cartridge extensions engage housing recesses to enforce orientation, prevent improper assembly, and support cleaner filter servicing.

A MOF-coated fibrous filter removes ions from CMP slurry while allowing abrasive particles to pass, improving semiconductor reliability.

Multiple filter baskets and a divided chamber support flows above 4,000 gallons per minute while limiting leakage and pressure drop.

A flexed filter edge conforms to the collection-tank aperture, blocking dirt particles while simplifying maintenance.

A nested opaque outer body and transparent inner body help a water purifier housing withstand pressure and water hammer while showing filter status.

Secondary liquid flow dilutes and agitates thickening fiber suspension, helping maintain vacuum and protect the fiber mat.

Separate O-rings can leak; this integrated filter seal combines mounting and multiple sealing features to simplify assembly.

Complementary ramps and perpendicular support regions guide plug-in rotation, securing exchangeable fluid treatment units in limited installation space.

Geometric connectors and color coding guide cartridge dispenser alignment, compatibility, and secure inline attachment without trial-and-error assembly.

Two independent vacuum circuits dry outlet screens, increase screening capacity, and remove fluid mist during deep-well drilling.

Water-repellent additives and fibrillated fibers help nonwoven filter media improve wet strength, flexibility, and processability.

Interconnected macro- and micropores retain therapeutic cells while supporting nutrient transport and functional maintenance in PCL tissue grafts.

Integrating the outlet pipe into the replaceable filter element reduces separate parts and simplifies low-cost filter manufacturing.

Nested porous layers combine pre-filtration, treatment media, and blocking filtration to remove bacteria, viruses, and cysts.

Hydroentanglement forms a gradient of out-of-plane elements that improves airflow and dust holding while maintaining filter-media tensile strength.

A helical support body inside the support tube prevents pleated filter collapse during backflow, preserving filtration efficiency and service life.

A rotating screw, basket brush, bottom wiper, and sealed cartridge support continuous solids removal while reducing leaks and maintenance downtime.

Different-density areas filter fluid in parallel, lowering differential pressure while maintaining filtration quality in a flat filter.

Locking slots and pedestal tabs position and retain the filter element, creating a seal that forces dirty fluid through the filter medium.

Primary and secondary keyways coordinate with latching mechanisms to secure the cartridge while supporting twist-to-unlock removal.

A removable vessel coupler enables aseptic media replacement between separated plant and liquid vessels without disturbing the plant side.
