Sewerage Structures TRIZ Cases
- Drainage Gutter Curved Side Wall Ventilation
Inwardly curved side wall creates air gap to stop capillary water accumulation without extra spacers.
- Customized Product Ranking via Demographic Segmentation
A system calculates product scores using user demographic profiles to generate customized popular item lists.
- Adjustable Drain Body Support Pan with Knock-Out Sections
Removable knock-out sections in the support pan adjust height and profile, reducing installation time for deep or narrow floor spaces.
- Sewage Grate Cleaning Mechanism for Clog Prevention
Hydraulic cleaning device clears grate blockages to maintain liquid discharge flow and prevent system overflow.
- Sewage Manhole Liquid Collection Tank Integration
A sewage manhole forms an integral liquid collection tank at its base to house a submerged pump.
- Stormwater Filter Cartridge with Solid Wall Float Tube
A stormwater filter cartridge uses a solid wall float tube to manage internal water levels and control fluid flow through the housing.
- Storm Drain Filter Bag with Anti-Backflow Skirt
An anti-backflow skirt prevents pollutant flushing during overflow while the porous bag maintains water flow.
- Drainage Channel Support Assembly with Dual-Mode Peg Coupling
A drainage channel support assembly uses pegs and coupling arrangements to anchor or suspend the channel structure above ground.
- Adjustable Drain Mouth for Tile Thickness Alignment
Telescopic drain mouths adjust liquid intake elevation to match final floor levels, resolving alignment issues caused by varying tile thicknesses.
- Tool-Free Connecting System for Flush Floor Profiles
A tool-free connecting element system secures flush-mounted flat profiles along a connection axis using form-fitting engagement features.
- Rotatable Promenade Drain Frame for Flat Roof Water Management
A promenade drain system uses a sliding connector to rotate the frame independently from the base.
- Clamping Element for Drain Channel Tile Alignment
Asymmetric clamping element prevents tile slipping during gutter assembly by securing segments before adhesive sets.
- Catch Basin Filter Absorber for Hydrocarbon Capture
Segmented filtration media captures 70% of hydrocarbons, resolving groundwater contamination while preventing clogging during high flow events.
- Vacuum Sewer Valve Control via Pressure Sensing
A vacuum sewer valve opens based on pressure readings from a sensor tube or suction pipe to evacuate sewage pits efficiently.
- Adjustable Float Gully System for Ice Prevention and Drainage
A buoyancy-controlled float valve blocks rising outlet gases to prevent ice formation while maintaining consistent drainage capacity.
