Membrane Filters TRIZ Cases

Integrated seals and springs in the filter cartridge block connections automatically, eliminating manual rotary valves to prevent leakage during maintenance.

A filter device with a spirally flushing function directs raw water in a rotating manner over the filter element surface.

Asymmetric tabs on the filter cap engage corresponding ledges to prevent misalignment and unauthorized cartridge use in water dispensers.

An integrated filter cartridge merges sealing and mounting functions into a single unit, eliminating multiple components and reducing waste during replacement.

Applying organic coating to foam edges before slurry impregnation resolves the strength versus porosity trade-off in molten metal filtration.

Surface-treated filter media increases water roll-off angle to coalesce droplets, resolving inadequate free water removal in diesel filtration.

Concentric melt-blown zones in tubular depth filters raise dirt holding capacity while maintaining low clean water pressure drop.

A filter device uses a flow divider to route excess backwash fluid directly to a tertiary stage, bypassing the secondary filtration unit.

Captive coupling connects the cover, filter element, and elastic compensation element to prevent contamination during disassembly.

Rotating coupling elements engage and disengage to transmit torque, eliminating mechanical bending stresses on connecting means during maintenance.

Segmented elongated filter baskets fit through standard pool deck openings to capture particles down to 300 microns, reducing maintenance frequency.

Integrating the vent into the replaceable filter cartridge eliminates erosion and clogging issues found in fixed support tubes.

Elevated retention edges in filter element passages direct particles toward the rotor shaft during disc rotation.

An alternating layer filter medium reduces pressure loss by eliminating redundant nonwoven fabric layers, improving filtration efficiency.

A buffer plate with openings and supporting posts absorbs pressure fluctuations, extending the service life of crude terephthalic acid filter frames.

Variable rotor speed in a toroid chamber maintains high velocity over the barrier, preventing clogging at higher pulp concentrations.

A filter assembly mount uses a lug and ramp surface to axially move a valve member, preventing fluid leakage when the element is not fully seated.

A movable endcap bypass plug transitions between sealed and unsealed states to relieve pressure buildup when filter media clogs.

Axial air-bleed conduit vents trapped gas from fuel filter housing, preventing back pressure and erratic fuel delivery.

A removable skimmer basket handle with a curved grip and T-bar base cap design.

A normally-closed vacuum valve opens automatically when the filtering apparatus locks to the cradle.

Hot area calendering melts the sheath of bicomponent fibers in a wet-laid web, achieving burst strengths above 10 bar while maintaining filtration efficiency.

Parallel cylindrical filter elements increase liquid volume flow capacity while reducing pump output during independent cleaning cycles.

Sintering compressed nanotubes forms covalent bonds that improve mechanical strength and conductivity for filtering applications.
