Sewerage Structures TRIZ Cases
- Tapered Precast Concrete Walls for Subsurface Storage
Variable wall thickness and modular connections resolve the contradiction between structural strength and material consumption in subsurface storage basins.
- Flat Wastewater Drain with Segmented Siphon Chamber
A flat wastewater drain uses a segmented siphon chamber to achieve high drainage capacity within a low profile.
- Shower Floor Sealing Membrane Insert
Tubular insert part joins flexible membrane to outlet pipes without adhesives, preventing cement soiling and leakage risks.
- Compact Drain Outlet With Siphon Channel
A compact drain outlet uses a siphon channel along the outer side wall to increase cross-sectional flow area.
- Low-Profile Dome Floor Drain Cover with Corrugated Surface
A low-profile dome floor drain cover uses concentric radial flow passages to maximize liquid drainage capacity.
- Floor Drain With Adjustable Height And Variable Immersion Pipe
Threaded base parts and cuttable immersion pipes adapt floor drains to low screed heights while maintaining liquid-tight seals.
- Drainage Cover Crossbeam Angled Ends Stability
Angled crossbeam ends lock into edge rail slots, balancing manufacturing simplicity with structural stability under dynamic loads.
- Water Separating Residue Filtration Unit for Slurry Dewatering
A fabric filtration liner and mesh screen separate water from high-pressure excavation slurry inside a container with an inner void.
- Variable Speed Vacuum Pump for Sewage System Energy Optimization
A variable speed vacuum pump adjusts rotation rate based on real-time sensor data to maintain stable suction pressure in sewage collection networks.
- Floor Drain Adapter with Jack Screws for Leveling
Jack screws in the adapter raise the grate flush with the floor, eliminating trip hazards from uneven installations.
- Bioretention Swale Overflow Filter for Peak Flow Management
A perforated pollutant retention device diverts storm water runoff through an upper framework to capture gross debris before it enters the drainage system.
- Removable Sealing Flange for Wet Space Drain Installation
A drain fitting uses a vertically oriented, removable sealing flange to adapt between wall-adjacent and distance configurations.
- Pump Unit Adaptive Control via Current Monitoring
A pump unit adjusts rotational speed using a lookup table correlating current consumption with target volume flow rates.
- Adjustable Floor Drain Cover for Flush Wall Installation
A guide-based adjustment unit moves a floor drain cover to resolve alignment issues in varied installation scenarios.
