- Holding Tank Subassembly With Leak-Free Bucket Interface
A bucket-shaped subassembly integrates the pump and seal at the tank top to cut connection leaks, simplify service, and relax tank tolerances.
- Holding Tank Pump Subassembly With Leak-Free Sealed Interface
A bucket-shaped pump subassembly creates a single sealed tank interface that prevents leaks, cuts assembly steps, and simplifies service.
- Portable Toilet Bowl Leveling for Stable In-Vehicle Use
An angled bowl, anti-slip base, and hose-linked container make liquid waste disposal more stable, private, and sanitary in vehicles.
- Variable-Volume Water Tanks for Flexible Camper Storage
Variable fresh and waste water tanks use flow sensors and pumps to share limited camper storage space and prevent overfilling.
- Glovebox Transfer Port Sleeve and Caps for Safer Material Handling
A flange-mounted sleeve with removable caps creates a controlled glovebox passage that cuts exposure, waste, and replacement effort.
- Portable Waste Water Tank Overflow System for RVs
An overflow inlet positioned above the bottom drains excess liquid while retaining solids, reducing emptying frequency.
- RV Wastewater Tank with Winch and Macerator Pump
A truck-mounted tank uses a macerator pump to lift waste water from an RV discharge point into the container for transport.
- Vehicle Toilet Cassette Leakage Prevention Mechanism
A vehicle toilet uses a coupled locking mechanism to seal the passage between bowl and cassette.
- Pivotable Toilet Base Unit for Compact Sanitary Space
A pivotable toilet base unit rotates between a sanitary area and a stowage area.
