Sewerage Structures TRIZ Cases

A hydrophobic nanoparticle barrier and float release mechanism seal storm water catch basins, preventing oil and chemical passage into drainage systems.

Segmented drainage system uses a filter screen and tapered geometry to separate sand from water, preventing blockages while ensuring rapid bunker drying.

A floor drain grating incorporates a displaceable segment that pivots to expose a gripping point for manual removal.

A yieldably deformable support cable and pivotally movable flow control vanes adjust tension to manage fluid entry into drainage infrastructure.

Threaded adjusting screws in floor drain spacers replace fixed-height inserts, eliminating the need for multiple spacer types and reducing construction costs.

Relocating sewer line terminations outside the building envelope prevents municipal backup intrusion while maintaining drainage functionality.

A siphon unit uses a latching mechanism and deformable collar to create a watertight seal without high pressing forces.

Outwardly extending flanges overlap adjacent edges to assemble modular floor drains, preventing water seepage through continuous waterproofing.

Overflow weirs and orifices in a sewage system separate excess flow from regulated discharge, reducing regulating reservoir capacity requirements.

Integrating the valve vault within the wet well eliminates differential settlement that breaks piping in separate structures.

An expandable locking drain screen prevents large object blockages in floor sinks by engaging pipe walls, enabling quick removal for cleaning.

A self-acting dredging structure uses a contraction and diversion device to separate water outlets and enhance flow velocity.

An adjustable shower drain assembly accommodates different tile thicknesses by allowing the covering element to shift vertically relative to the trough.

An adjustable floor drain support plate eliminates concrete chiseling by extending legs beyond the pour area for precise height positioning.

A lifting station adjusts pump motor speed using historical flow data to match actual drainage requirements.

A drainage channel uses an undercut to house a heat exchanger unit within the lower section while maintaining a slim upper profile.

A grinder pump directs waste flow via baffles and grinds solids with a rotating blade, ensuring complete evacuation without clogging or high motor torque.

Concrete form uses pre-formed notches and drill template markers to align bath filler supply lines, preventing tile damage during installation.

A drain cover element forms a fixed connection with the retaining element to conceal mounting screws from view.

Injection molding process creates drainage grids with arc-shaped cross-sections and inverted T-ribs for robust structural integrity.

Flexible expansion joints accommodate thermal expansion in precast concrete sections, preventing cracks while maintaining structural integrity.

A sewage basin assembly uses a hanging member and modular access cover to enable easy installation of internal components.

A float-driven cleaning apparatus moves a brush over a detention well discharge opening to remove debris without external power.

Segmented waste tank cover allows independent service of technical equipment while maintaining liquid-proof separation from the waste compartment.

A drainage cover uses spacer elements to define water passage width and support flooring components.

A drain with a unidirectional passage directs external water inward while blocking internal flow.

A drainage inlet uses a movable flange to adjust position, preventing tile misalignment and clogging.
