Membrane Filters TRIZ Cases

A self-contained filter assembly uses a magnetically coupled impeller to circulate and clean the deburring solution within a magnetic barrel tumbler.

Noncircular pilot features prevent fluid bypass and ensure correct installation orientation.

A filter support structure uses elliptical fluid passage openings to enhance mechanical stability.

Segmented holder and disposable sock eliminate cleaning time while maintaining filtration function.

Auto-ejecting interface uses gravity to release filter cartridge, reducing axial force needed for removal and preventing fluid exposure.

An asymmetric groove and pin on the filter element engage a housing channel to prevent counterfeit parts from impairing performance.

A filtration device uses asymmetric protruding and recessed portions to constrain non-genuine component insertion.

A glass-free non-woven filtration media blends synthetic staple fibers with fibrillated cellulosic fibers to form a porous structure.

Radial fins on a rotating shaft extract dry cakes from pressurized disc filters, preventing shock risks and wear.

Segmented flow paths isolate dispensing ports from velocity fluctuations, ensuring stable chemical delivery during pump cycles.

A retrofittable attachment uses a ball and divider to block fluid flow when unauthorized filters are installed.

Segmented drum flights and adjustable trunnions resolve torsional strength conflicts during solid removal, reducing waste water generation.

A tapered oil filter removal tool uses reverse threads to grip the filter base while a cavity captures spilled fluid during extraction.

A fuel filter insert uses a gradient-free coalescing medium layer to separate water droplets from fuel efficiently.

Sealed closure system for a cartridge filter uses a disc-shaped sealing plate with an o-ring seal and integrated stop to prevent axial movement.

Negative pressure within the flexible envelope adheres the cover to filter elements, preventing shifting during insertion into positioning frames.

Plastic nozzles replace soldered metal sockets in the filter cover, reducing production costs while maintaining crash resistance.

Cam surfaces on filter caps convert rotation into linear force, simplifying replacement while maintaining secure assembly.

Asymmetric keys on the filter element prevent incorrect mating while the nested bayonet structure withstands high internal pressure.

A filter assembly uses a sloping side wall face to guide the protrusion of a tubular filter element during axial removal.

Spacing members segment the filter media to prevent pleating under pressure, extending lifespan and reducing installation time.
