Spray nozzles and mixing and drain eductors rinse, disinfect, and send toilet tool waste directly into the bowl for cleaner storage.

A pivot-sliding toilet cover linkage enables automatic or manual opening while protecting the drive and keeping the user-facing surface clean.

A PMMA-PTT resin blend for household plumbing parts improves solvent resistance while preserving surface hardness and water resistance.

Varying-length refill tubes and a slotted manifold wash the full toilet bowl and refill the pool while keeping water use low.

A rim-adhered membrane with a handle aperture contains sewage splash during plunging or brushing and wraps the tool head to prevent drips after use.

A rigid retaining mat stabilizes a toilet during installation or removal while its raised lip catches draining water and protects flooring.

Infrared sensors in a toilet track excrement and perineal temperature to estimate body temperature without user action or contact.

A rimless bowl, rinsing seat, and UV-activated titanium dioxide coating improve cleaning, reduce streaks and clogs, and control microbes.

A plug-in mounting plate routes water and power lines safely, enabling fast tool-free lavatory installation without crushing connections.

An adaptable shroud and chamfered seat close toilet gaps at the wall and floor to prevent ligature points across varied plumbing layouts.

A keyed adapter and receiving channel limit rotation, center the fastener, and prevent misassembly or grub screw damage in sanitary object mounting.

A three-port valve sends a measured water flow to a separate basin, flushing liquid waste with less water than a full toilet bowl flush.

Sensors track toilet paper use and bowl displacement so flush volume and duration can prevent clogs, overflows, and water waste.

A pre-wall service opening placed outside the flush reservoir footprint improves maintenance access and frees secondary space for storage or dispensers.

An elastic core inside a soft seal follows complex toilet bowl gaps to block water intrusion, ease cleaning, and support lower functional-part height.

Combining elevated foot platforms with a removable receptacle improves defecation posture while adding storage and saving restroom space.

Water line pressure lifts and lowers the toilet for wheelchair-friendly use while preserving drainage and reusing the same water for flushing.

By routing a portable receptacle through a building roof vent, workers can dispose of waste on site without heavy tanks or hazardous restroom trips.

Rapid piston withdrawal creates suction at the drain outlet to clear HVACR condensate clogs without cutting lines or blowing debris into the unit.

Controlled pressure pulsation and air mixing alternate dense and wide wash jets to improve comfort and reduce water use.

Alternating pressure pulses form large slow drops and fast small drops, combining volume and stimulation while using less wash water.

Fastening moves behind the front panel through a rail, simplifying sanitary element assembly while preserving panel appearance and material choice.

A stirring chamber and controlled mixer recycle and purify urine for flushing, cutting tap water use while maintaining toilet cleaning.

Load-bearing footrests and rear support convert a sitting toilet into a supported squat posture that eases evacuation and reduces leg strain.

Internal cameras detect user anatomy and conditions to auto-position bidet nozzles, improving cleaning accuracy and reducing misdirected spray.

Blending PMMA with PTT improves solvent resistance while preserving surface hardness and water resistance in wet area plumbing fixtures.

Injection-molded resin composites replace ceramic firing to deliver strong, smooth sanitary ware with lower energy use and better self-cleaning.
