Membrane Filters TRIZ Cases

Ion beam surface pretreatment helps metal or metal oxide coatings stay bonded on polymer filters while improving UV durability and antimicrobial function.

A separate snap-fit connecting ring forms the threaded filter interface without seaming, cutting contamination, waste, and assembly complexity.

An integrated annular seal replaces separate O-rings to prevent canister filter leaks while simplifying assembly and maintaining fluid flow.

A slotted center-tube lock secures the filter element and seals the flow path so dirty fluid passes through the filter medium without bypass.

A raised endplate wall seals against the secondary filter to block bypass, verify fit, and simplify cartridge removal during service.

Combined rotation and short axial movement divert startup polymer melt past the filter, reducing contamination, seal wear, and valve complexity.

A self-closing inlet valve and filter-element pin prevent fuel spillage during service and block operation without a proper filter.

Floats and flexible air conduits lift and reposition air scour components in treatment units without dismantling rigid piping.

Vacuum-assisted continuous filter belts separate drilling slurry while limiting vibration, noise, emissions, and belt wear.

Magnetic resonance coupling lets a filter element IC tag communicate across a metal partition wall without slits, preserving housing strength and design freedom.

An axial pin opens the inlet only when the filter is installed, ensuring the blocking element reseats and stops unfiltered fuel flow.

A downward jet fluidizes filter media inside the vessel, removing contaminants while avoiding scrubber fouling and costly top-mounted pump maintenance.

A sealed coupling and check-valve let sanitary water filters be replaced without tools while limiting backflow and contamination.

A single piston-and-spring valve inside the manifold bypasses a clogged filter and shuts off fuel during replacement to prevent leakage and downtime.

Pressure-responsive flaps bypass a clogged filter and support filter replacement without shutting down the fuel supply.

Ultrasonic self-cleaning keeps cutting fluid filter screens clear, sustaining flow and filtration without manual disassembly.

Pre-assembled retaining elements center and axially hold the filter element, simplifying replacement while reducing maintenance height.

Pressure-actuated flaps integrated into the filter assembly bypass clogged media and keep fuel flowing during filter replacement.

A keyed holder and vertical screw adjustment enable tool-free cartridge connection while preventing misorientation, twisting, and pressure misalignment.

Reverse-flow purging and refill through a valve assembly let a reusable oil filter be cleaned in place, reducing replacement downtime and waste.

Asymmetric pins and matching protrusions lock a fluid filter cartridge into the correct housing orientation, simplifying manufacture and preventing misassembly.

A removable pre-filter and primary filter in one housing enable inline water filtration with easier cleaning, replacement, and less disposal waste.

A keyed locking head and latch guide filter insertion, prevent misalignment and over-rotation, and enable easy twist-to-unlock removal.

A threaded, sealed adapter lets spin-on filters fit cartridge bases, cutting filter change time and reducing fuel spillage.

Uncoupled filter media layers and downstream smaller pores enable dense pleats that raise dust holding capacity while limiting clean pressure drop.

An asymmetric indexing element guides an off-centre plug into correct position, preventing misalignment, debris, and seal leakage in engine filters.

A split valve design moves the return member to the assembly, cutting soiled areas and enabling incinerable cartridges with adjustable opening pressure.

An elliptical sealing interface and alignment projection prevent cartridge rotation, maintain sealing, and reduce water exposure to filter media.

A rotatable, detachable filter element lets service teams replace only the clogged insert, cutting housing waste while staying secure under vibration.

A curved center-stack surface guides the filter pin into place, limiting torque, preventing cocking, and reducing air capture during installation.

A sensor flap and flow-path module automatically drains collected water from a diesel fuel filter to prevent injector corrosion and efficiency loss.

A draft tube separates gas and fluid backwash zones to clean layered wastewater filter media while preserving the interface between media layers.

A rotating removable filter element lets the housing stay in place during service, cutting waste and maintenance cost in fluid filtration.
