- Dual Odor Trap Urinal for Odor-Free Seal Replacement
A second odor trap keeps drain gas sealed during urinal seal replacement, enabling immediate reuse and reducing odor release.
- Resilient Urinal Outlet Cartridge for Anti-Jamming Removal
Resilient locking projections let a removable urinal outlet cartridge clear mineral build-up, easing extraction and reducing odor-related maintenance.
- Dual-Bag Urine Stowage for Spacecraft Water Recovery
A dual-bag urine stowage system switches storage automatically, controls odor, and supports onboard water recovery in spacecraft.
- Toilet Excrement Monitoring Using Thermal and Strain Sensing
Thermal imaging and strain gauges distinguish urine from feces in a toilet, enabling accurate excrement type and mass measurement.
- Helical-Fin Odor Trap Cartridge for Waterless Urinal Sealant Recovery
Helical fins in a waterless urinal odor trap redirect stray sealant back to the barrier layer, extending seal life and reducing maintenance.
- Toilet Bowl Nozzle Ring Layout for Siphon Transition Cleaning
Targeted nozzle rings focus high-energy flush jets on the bowl-to-siphon transition and siphon surface to improve cleaning with minimal water.
- Dual Gravity Drain Valve Core for Waterless Odor Sealing
Dual downward-sloping valves block drain odors and backflow without flush water or chemical sealants, while resisting debris and freezing.
- Urinal Odor Seal Replacement With Continuous Gas-Tight Closure
An added odor trap closes during replacement to keep the urinal usable and prevent ammonia odor escape in large facilities.
- Flushable Urine Funnel for Splash-Free Standing Use
A biodegradable funnel directs urine into a commode from a standing user, reducing splatter, cleaning, odor, and installation burden.
- Spacecraft Urine Stowage Switching for Continuous Water Recovery
Automatic switching between urine storage bags and processing keeps spacecraft waste handling continuous and supports potable water recovery.
