Suction Filters TRIZ Cases

A locking and ejection mechanism keeps the dirt bin aligned and secure while allowing easy removal without air leaks or accidental detachment.

A forward-cantilevered motor offsets the upright body's moment at the pivot, reducing user fatigue and improving vacuum maneuverability.

A front-inlet, rear-outlet uniflow cyclone and external dirt chamber keep airflow clear and maintain hand vacuum cleaning at different angles.

Counter-rotating agitators sweep debris into a focused inlet and removable chamber, cutting suction time, power use, and manual cleanup effort.

Repositioning the motor and cyclone axes improves hand feel, sustains airflow, and removes separate conduits in a hand vacuum.

Upwardly curved sole plate ribs create semicircular gaps so debris passes under instead of clogging, improving vacuum pickup across carpet piles.

A cover element shields the closure spring from dust buildup, helping the filter bag holding plate lock and close reliably.

Removing the vortex finder and using a screen cuts back pressure, helping low-power vacuum cleaners keep airflow and battery life.

A low-profile upright vacuum repositions the air treatment assembly and suction motor to clean under furniture without losing dirt capacity.

A vertical pre-motor filter and lower cyclone layout keep airflow steadier for longer while improving hand vacuum ergonomics.

A layered insert made from cutout filter material expands surface area to keep vacuum suction high longer while lowering bag production cost.

A detachable suction unit expands cleaning beyond floors, while an automatic cord reel simplifies storage and reduces manual winding.

Bottom-mounted electromagnetic sensing detects dust buildup in a cyclone chamber to signal a full dustbin without false readings.

A forward motor, horizontal cyclone, and porous pre-motor filter improve hand feel and sustain airflow by reducing clogging.

A perforated insert with spacer ribs keeps the filter bag off the vacuum chamber wall, preserving airflow and suction while containing fine dust.

A hinged lower cover and rotating compression member let separated dust and fine dust discharge together with less scattering and simpler emptying.

Opposing hose coil springs and a low-center-of-gravity layout cut extension force, prevent collapse, and sustain airflow for above-floor cleaning.

A rotatable outlet grill uses cyclone airflow and centrifugal force to resist clogging, maintain suction, and simplify dust removal.

A removable cup holder conceals the vacuum port, improving hose access and cabin appearance in an on-board vehicle vacuum system.

A porous mesh bag and pivot attachment let a leaf blower collect mixed lawn debris efficiently without ballooning, blower damage, or hard emptying.

A hook-and-stop coupler links a pre-separator and vacuum so one worker can move both, cutting filter replacements and relocation effort.

An upright vacuum unlocks its removable cleaning pod automatically in the floor position, avoiding cleaning stops and improving reach under furniture.

A vacuum chute and bag cartridge collect pet waste without direct contact, then seal and release the bag to contain odor and leakage.

A rotatable bag cuff and diffuser let a blower vacuum bag shift position, reducing user wetness and bag wall abrasion.

Thermoformed and stamped thermoplastic film replaces cardboard or injection molding, enabling strong ultrasonic welding to nonwoven vacuum bags.

A detachable cleaning unit and flexible airflow conduit improve upright maneuverability without reconfiguring suction paths.

A selectable battery or cord reel with PWM-based motor control cuts vacuum weight, cost, and circuit complexity without manual mode switching.

Surface folds expand filter area to cut pressure drop, preserve suction, and extend dust bag service life as the bag fills.

A dual-position handle pivots to the front or rear, letting the cleaner reach under furniture while folding compactly for storage.

A movable arm and pulley bearing assembly selectively tensions the belt, letting the agitator engage or disengage for carpet and hard-floor cleaning.

Multiple folds expand filter area to cut pressure drop, preserve suction as the bag fills, and extend dust holding life.

A rotating vertical motor and lever linkage loosen or tension the belt, shrinking motor housing area while keeping brushroll drive stable.

Battery power replaces the cord reel while floor-status control adjusts BLDC suction, improving mobility and cleaning performance.

A centrifugal separator splits heavy and light debris before the fan, preventing fan-case damage while preserving suction force.

A removable dual dust collector boosts vacuum filtration and suction while letting both collectors be emptied together with less handling.

Material-strip diffusers with elongated openings swirl dust-laden airflow inside the vacuum cleaner bag to prevent inlet clogging and extend service life.

A shielded composite vacuum bag uses non-woven filtration media and an internal polypropylene protector to resist abrasive debris and maintain dust capture.

Repositioning the motor and cyclone with a porous pre-motor filter improves hand feel and maintains airflow by reducing clogging.

A longitudinal pre-motor filter and forward motor layout reduce clogging, sustain airflow, and improve hand feel in a hand vacuum.

A removable cleaning unit switches between AC and DC suction to improve airflow, maneuverability, and easier dirt chamber emptying.

A forward cyclone and longitudinal porous pre-motor filter improve hand feel and sustain airflow by reducing backpressure in hand vacuums.

A collar-and-rib deflector creates low-speed zones that retain waste, cut recirculation, and avoid hair snagging in bagless vacuum cyclones.

Removable dust suction panel modules isolate clogged hair and fibers, simplify cleaning, and help prevent debris scattering after suction stops.

A vertical cyclone and pre-motor filter layout improves hand feel and keeps airflow steadier by reducing clogging in hand vacuum cleaners.

Recycled textile fibers and binding fibers form a nonwoven vacuum bag that preserves dust separation, service life, and dust storage capacity.

A removable supplemental bin expands stick vacuum dirt capacity while preserving lightweight handling and above-floor cleaning flexibility.

A claw-based lock secures the vacuum filter center post without elastic interference, preventing aging-related detachment and easing replacement.

Separate waste and fine-dust containers with a movable lid and diverging conduit improve emptying, transport, and recirculation control.

Split adapter plates mount separately to secure cleaning-device containers while cutting weight, material use, and transport handling issues.

A segmented upright vacuum layout shifts cyclone and motor placement to reduce body depth and clean fully under furniture.
