Suction Filters TRIZ Cases

A nested dirt chamber under the motor improves hand vacuum balance and lets users empty the cyclone bin without disconnecting tools.

Spiral blades, collecting grooves, and a cutting member keep carpet-cleaning drum brushes from clogging with wound debris and losing rotation.

A dual-cyclone layout places the dust box between inclined guides to expand capacity, preserve low height, and maintain suction force.

By combining fan pressure drop and motor current to estimate flow, this case detects air filter pollution accurately despite power setting changes.

Splitting dirt separation before and after the impeller preserves inlet suction, removes coarse dirt, and reuses airflow for motor cooling.

A flexible closure, sealed lid port, and suction source contain dust and allergens during cyclone bin emptying into a refuse container.

A vertical motor and porous pre-motor filter improve hand vacuum comfort while delaying clogging and preserving airflow.

A removable dirt chamber and integrated cyclone-nozzle assembly allow easy washing and emptying while keeping the motor protected from water.

A rotating cover body pushes segmented clamps onto the filter cage middle column, improving dust collector assembly speed and fixation stability.

A fragrance-loaded polymer matrix bonded to a vacuum filter deodorizes exhaust air while preserving airflow and suction performance.

A vertical motor above the cyclone and a porous handle filter improve hand feel while maintaining airflow longer by delaying clogging.

A self-locking bin and spring ejection mechanism improve alignment, airflow sealing, and safe removal in handheld vacuum cleaners.

Direct wheel coupling removes gear friction so the cleaner moves smoothly by hand, resists wobble in turns, and protects the motor from water.

A nested two-stage cyclone and surrounding screen keep hand vacuums compact while preserving dirt separation and access to tight spaces.

A spring-loaded flush inlet uses slight foot pressure and a micro switch to collect debris neatly while avoiding accidental activation.

Forced air cooling in the maintenance station prevents fan motor overheating during dirt discharge, protecting robot cleaner durability.

A vertical porous pre-motor filter and motor-above-cyclone layout improve hand feel while sustaining airflow as the filter loads.

A spherical rolling assembly and pivoting separator shift the center of gravity for quicker turns and better stability around obstacles.

A rigid wand with a nested flexible hose lets the cleaner switch between stable upright use and adaptable handheld or canister cleaning.

A non-uniform cyclone outlet gap improves dirt separation and airflow in hand vacuum cleaners without relying on a uniform gap structure.

Multiple dry-laid nonwoven plies increase dust-holding capacity while preserving airflow and low pressure loss in a vacuum cleaner filter bag.

An internal diffuser with elongated openings swirls dust-laden air inside a flat vacuum bag to prevent inlet clogging and extend bag life.

A toroidal partition wall and multi-cyclone layout separate liquids in a compact wet vacuum while preventing backflow into the cyclone.

A removable suction duct stored in a tank-formed cavity avoids shocks, hides dirt, and stays easy to inspect and clean for clogs.

A removable mounting member simplifies access to the motor and cyclone stages while reducing weight and enabling portable cleaning modes.

A movable rotating shaft locks the dust collection unit during lifting, preventing accidental cleaner detachment without extra parts.

A hollow handle air path and non-cyclonic filter assembly improve debris capture, cut airflow resistance, and reduce hand torque.

Movable motor-driven plates compress debris inside a robotic vacuum bin, increasing capacity and reducing emptying frequency with resistance sensing.

A two-tier cart, hopper, hoses, and shock-corded bag turn leaf vacuuming into one mobile step for collecting, filling, and moving yard waste.

A metal sidewall sealed to a polymer base simplifies wet/dry vacuum manufacturing while reducing leak points and improving durability.

Matching the motor-fan curve, filter bag geometry, and port dimensions cuts vacuum power use while preserving strong carpet dust pickup.

A retaining part separates the filter bag from the liquid delivery space, preventing blockage and keeping wet suction and pumping reliable.

Coordinated motor-fan, filter bag, receptacle, hose, and tube sizing cuts vacuum power use while maintaining strong dust removal.

Pressure taps and a float cut motor power as liquid nears drum capacity, preventing overfill damage without operator monitoring.

Concentric ridges and channels spread exhaust air under the canister base to keep the vacuum level, stable, and easy to move across floor transitions.

Injection-molded bristle stiffeners keep tufts erect and reduce flexure, improving vacuum cleaning while lowering brushroll power use.

Thermoformed thermoplastic film cuts holding plate cost while enabling strong ultrasonic welding to non-woven vacuum cleaner bags.

A separable one-handed vacuum collects pet waste without bending or direct contact, reducing strain and exposure for users with limited mobility.

A nested cyclone and dirt chamber let a low-profile cleaning head reach under furniture while maintaining filtration and dirt capacity.

A rear-axis uniflow cyclone and separate lower dirt chamber cut airflow bends and inlet blockage, improving suction and dirt collection.

A horizontal uniflow cyclone with a front inlet and rear outlet cuts backpressure and improves dirt collection in hand vacuum cleaners.

A two-stage cyclone with a tapered second inlet and helical vanes improves fine dust capture while limiting dirt re-entrainment in exhaust air.

Relocating the motor between the inlet and dust cup cuts handle vibration, moves exhaust away from the body, and simplifies dust cup removal.

Counter-rotating agitators sweep debris into a narrower rear suction inlet, cutting energy use while improving low-profile cleaning access.

A protruding upright dust separator makes the bin easier to empty, adds bump protection, and preserves 360° sensor visibility.
