Mechanical Cleaning TRIZ Cases

A non-contact NACA duct scavenges dust-laden boundary-layer air from moving paper webs, cutting noise, power use, and fiber loosening.

A movable nozzle and fluid conduit drive cleaning solution deep into carpet fibers while keeping dispensing controlled across surface types.

Movable cleaning members engage agitator friction surfaces to cut away hair and fibers, maintaining rotation while reducing noise and vibration.

Maintaining elbow cross-section at least equal to the inlet reduces vacuum cleaner clogs and preserves airflow without clean-out ports.

Directional valve timing limits sootblowing steam to lance motion, cutting steam use while maintaining recovery furnace cleaning efficiency.

Distributed suction openings along the banknote path remove dust before it reaches optical sensors, improving checking accuracy and uptime.

A dual-trigger removable dust cup lets debris be released with less direct handling, reducing user exposure to dirt during vacuum emptying.

A smooth perforated jacket keeps rotating nozzles centered in hose filters, preventing damage and reducing static charging during cleaning.

A movable auxiliary wheel raises the suction mouth for easier strip repositioning and adds pre-brushing in one moquette cleaning machine.

Cam-guided alignment and anti-rotation locking keep an upright vacuum stable in storage and release automatically for floor cleaning.

Disposable flexible liners, suction coupling, and a piston scraper reduce canister handling, waste volume, and clinician exposure.

Inclined and guided brush cleaners move wound hair to the center and out to the dust collector, preventing brush faults and lost cleaning performance.

Switching inert gas between circulation and directional exhaust purges the transfer chamber, limiting organic adhesion and preserving film quality.

A tilt-activated power switch and automatic pressure control keep steam output steady while preventing overheating and unsafe pressure buildup.

Image-based brush adjustment keeps fiber-to-needle spacing precise in fabric finishing machines, cutting manual setup time and wear-related stoppages.

Using the vacuum generator's airflow through the battery compartment controls battery temperature during use and charging without separate cooling hardware.

Vacuum ports and a perforated table pull dirty rinse water through the rug, cutting manual passes, residue, and drying time.

Movable front and rear sealing plates adapt the suction head to floors and carpets, boosting airflow, pickup, and debris control.

A torsion-spring steering assembly stores handle motion energy to turn the cleaning foot smoothly and reduce user fatigue around obstacles.

An oscillating movable surface creates a synthetic jet that dislodges carpet dust and transports it with lower noise and power use.
