Sewerage Structures TRIZ Cases

Vitreous-fiber buffering absorbs storm water quickly for low-disruption installation.

This case uses localized reinforcement walls in road well covers to balance compressive strength, weight, cost, and drainage.

Interchangeable drain components use threaded adjustment and sealing to fit varied floor construction without costly re-installation.

A drain-and-seal assembly uses a flexible membrane and fixing plate to achieve watertight corners with adjustable installation.

This case uses a separable, flexible ring to remove a fixture cover after concrete hardens while preserving adjustability.

Raised ribs in corrugated drainage columns reduce stress and displacement when surface units are stacked for greater depth.

A centrally held intumescent layer foams outward to seal the floor drain and limit fire and smoke spread without sealing water.

A divided catchment basin uses an air gap, passive drain plug, and spillway to manage flow and protect municipal water supplies.

A planar body and orthogonal fingers guide pooled tile water through a drain path, helping limit standing water from surface tension.

A fixed-and-loose pipe coupling uses guided transverse movement and a handle for media-tight installation from above ground.

A smaller upstream filter and larger downstream filter handle flow changes while reducing equipment, area, and operating costs.

Machine learning analyzes acoustic signals to locate illegal sump pumps, reducing labor costs and equipment wear.

A waterproof cement floor covers a gravel layer and perforated conduit to direct water flow toward a drainage pit.

An alarm management module processes filling level and pumping capacity variables to trigger intervention alarms only when specific conditions are met.

An integrated drain channel with a restricted cross-section enables controlled drainage of accumulated water through a pin-operated closure mechanism.

Denser coupling chambers anchor channel modules against buoyancy, reducing installation time and traffic disruption.

Segmenting the filtration into removable layers resolves clogging risks from hair while preserving aesthetic integration with surrounding materials.

Segmented strip material adjusting frame nests inside container edge to resolve tiling obstruction while maintaining structural strength.

A resistance hanging screen uses counterbalance weights to bias the filtration device toward a closed position during low water flow.

A drain sensor assembly uses ultrasound reflection to determine filling levels in drainage elements.

A shower drain unit uses a curved siphon wall to direct water flow efficiently into the union.

A dismountable gutter siphon system uses a sliding collecting tray to enable easy cleaning of interior components.

Pre-installed rotating valves seal gutters instantly, eliminating time lost retrieving portable barriers during fuel leaks.

A drain pipe joint device uses a resilient annular seal integrally connected to a structural tube for waterproof sealing engagement.

Adjustable peripheral strip in shower drain adapts to tile thickness using spring steel, concealing finishing layers while preventing moisture accumulation.

Integrated frame grips and pegs align cover units on channel bodies, eliminating screw installation complexity while preventing lifting.

Randomly varying the start liquid level and time delay for each pump enables automatic alternation, preventing grease buildup and reducing wear.

Segmenting the closure element allows workers to replace worn flap gates without dismantling the reservoir or outlet piping.
