A fan-assisted holder dries and stores a wet toilet brush to limit mold, bacteria, and clutter around the toilet.

A floor-secured scrubber combines abrasive zones and a detachable bristle pad to remove calluses and clean feet safely without bending.

A terpene-based solvent system separates carpet polymers with higher recovery yield and less organic solvent use for second-generation carpet.

Rigid plastic anchoring studs strengthen the bond between a deformable metal core and viscoelastic grip layer to prevent cracking and bacterial ingress.

Rotation cams lift and engage fur-removing pins to disentangle hair and pet fur on carpets, then guide it into the suction port.

A terpene-containing solvent selectively extracts carpet polymers, improving fiber recovery while reducing solvent use and recycling waste into new carpet.

Integrated brush rows in the wiping blade remove stubborn dirt, ice, and sleet without complex holders or chemical cleaners.

A movable collection surface releases stored hair with a simple press, improving drain protection and making disposal easier in bathing areas.

Pressure sensing in the toothbrush grip replaces small buttons, enabling hygienic mode selection without visual contact.

U-shaped side channels help one brush define waves, curls, and coils while reducing frizz and improving hair smoothness.

Multiple outlets along a J- or U-shaped arch dispense dentifrice at once, improving coverage while keeping the cleaning mouthpiece compact.

A recessed inner bristle reservoir and outer bristle zone improve powder pickup and spread, reducing streaks and repeated reloading.

A grouped bristle layout combines concave, convex, and inclined transverse elements to improve plaque removal across varied tooth contours.

Dispersed crimped yarn in the brush member limits paper dust leakage and filament splitting, reducing charging failures and image defects.

An elbowed applicator with transverse bridges deposits makeup and combs brows in one step for faster, more precise density and definition.

A concave flocking layer fed through an integrated discharge path improves lip fit and material delivery for more precise makeup application.

A dual-container pump and elastic support structure keeps mascara from drying, enables dilution of hardened liquid, and helps prevent leakage.

Two applicator elements with different hardness give one cosmetic tool flexible and rigid surfaces for varied touch and application effects.

A chisel-shaped tip with long tapered synthetic filaments improves paint flow, finish quality, and painting distance in detailed architectural work.

Brush property sensing adjusts brushing time and technique to improve cleaning consistency across different toothbrush types.

Elastic foam pads with curved recesses improve tooth and interdental cleaning while reducing stress on enamel and gums.

A closable valve and contoured single-piece brush apply creams or gels without hand contact, reducing contamination and air exposure.

Passive capillary flow feeds fluid from a reservoir into bristle tufts to avoid clogging, improve whitening pH control, and sanitize bristles.

A segmented brush head, drive rod, and securing element simplify replacement and cleaning while reducing wear, noise, and energy use.

A modular brush head coupling uses a drive rod and locking element to cut wear, noise, assembly difficulty, and energy use.

A flexible brush with a stiffer backing cleans pet paw crevices and legs thoroughly while adapting to different paw sizes.

Corona-polarized piezoelectric toothbrush filaments retain bristle toughness while generating surface charge to inhibit bacterial growth.

Ball-driven ejector pins clear dandruff and grease from porous comb teeth while making the comb easier to clean and reuse.

Thin plastic spacers between bristle disks set axial spacing precisely, improving mascara deposit and eyelash separation without new tooling.

Auxiliary walls buttress a flexible applicator tip, adding gradient resistance and spring-like tactile feedback without losing structural support.

Mixed rounded and chemically tapered split-end bristles clean tooth surfaces and interproximal margins while limiting gingival irritation.

A turning-and-moving brush with side brushes cleans inner, outer, and top tooth surfaces while adapting to dental arch contours.

A priming chamber, filter, and annular flow restrictor plate keep adherent sunscreen powder flowing evenly while reducing clogging and streaking.

Movable front and back brush modules adapt to different mouth shapes while cleaning incisors and molars more efficiently and comfortably.

A core-sheath bristle balances plaque removal and tooth polishing by combining an exposed friction tip with a rougher sheath surface.

Independent front and back brush modules combine translation and rotation to clean incisors and molars while fitting different mouth shapes.

An automatic stand and concealing cover lift or enclose toothbrush bristles at rest to prevent surface contact and contamination.
