Sewerage Structures TRIZ Cases
- Well Flow Controller With Variable Inlet for Clog-Resistant Drainage
A variable inlet opening and level sensing inside a well adjust rainwater and groundwater flow to prevent clogging and overflow.
- Drainage Outlet Orifice Structure for Blockage-Resistant Flow
Protrusions and segmented outlet openings redirect liquid, limit sediment buildup, and keep drainage flow stable under blockage risk.
- Universal Baseplate Tabs for Multi-Size Drain Basin Assembly
Multiple tab sets let one base plate fit different drain basin sizes and inlet castings, cutting parts, labor, and assembly time.
- Shower Drain Sealing Ring Assembly for Pressure Leak Testing
A test membrane and O-ring sealing ring assembly enable pressure testing of shower drain seals before final installation, avoiding caulking.
- Sewer Cleanout Sensor Cap for Backup Detection Without Spillage
Electrode sensing in a sewer cleanout cap detects backups and sends wireless alerts while avoiding risky cap removal and spillage.
- Drain Trap Float Seal for Odor Blocking and Fluid Drainage
A floating rounded seal in a fluid well blocks drain gas and odor while sidewall openings maintain effective fluid drainage.
- Adjustable Waste Outlet Assembly for One-Sided Sealed Installation
An adjustable two-section waste outlet uses a compressible tubular seal to enable one-sided installation and a secure watertight fit.
- Floating Disk Drain Trap for Reliable Odor Sealing
A buoyant disk in the drain well rises to seal the inner part, retaining fluid and blocking gas or odor escape from floor drains.
