Sewerage Structures TRIZ Cases

A floor drain fitting uses a pocket-like bulge to form an overflow duct alongside a removable odor trap container.

A flexible bladder accommodates sewer gas pressure fluctuations, protecting odor-absorbing media from rapid depletion and extending its operational lifespan.

Appliance ribs on the U-shaped channel anchor accessories to resist buoyancy forces from wet concrete, ensuring stable drainage.

A plate-like floor drain cover connects to an annular positioning element that defines a water inlet gap for tile integration.

Segmented drain cover assembly uses nested components to conceal protruding hardware and match vinyl liner appearance without compromising fluid flow.

Plate check valve uses guide rods to align the valve member, preventing spherical float jamming and ensuring sufficient discharge capacity.

A floor drain uses a laminated glass plate to form an upper inlet slot that eliminates dirt edges.

Replacing mechanical clamps with an adhesive seal reduces assembly complexity and time while maintaining high-intensity, watertight connection strength.

Modular bioretention fixture cells integrate high-flow bypass structures within sidewalls to manage storm water runoff efficiently.

Slanted grating deflects water flow toward the drain downpipe, preventing backflow during heavy traffic washdown operations.

Blades promote vortex flow while segmented seals prevent evaporation, stopping sewer gas leaks in floor drains.

Hinged shielding film opens with rainwater flow to prevent offensive odors and insect infestation from drain ports.

Pressed barrel arches eliminate crevices to reduce bacterial growth while maintaining structural strength.

Segmented adjustment elements enable precise height control, resolving assembly complexity in facade drainage systems.

An integral mounting flange with outwardly bent anchors secures a floor drain in cast floors, eliminating separate fittings.

A sewer monitoring system adjusts measurement range limits dynamically to correct sensor errors caused by manhole obstacles.

Segmented light liquid separation device resolves volume and efficiency contradictions by retaining floating liquids in a dedicated chamber.

A PCI-Express switch routes response packets using unique node identifiers assigned to each communication channel.

A plate-like inlet member uses a peripheral elevation for lateral fixation to reduce the sealing layer contact line.

An adjustable stormwater drain insert uses an oleophilic fabric and central sediment bag to capture contaminants.

A square sewer cleanout with a planar face aligns with interlocking pavers for secure installation.

Hydrophilic polyurethane foam maintains water-holding capacity under compressive forces through controlled chemical composition, supporting green roof systems.

Unidirectional seals close the outlet connection to stop odor leakage while allowing liquid to pass freely, removing the need for a bulky siphon.

An arcuate insert manages high flow rates in a hydrodynamic separator, preventing scouring and washout of sediments.

A lower guide plate distributes liquid radially outward to ensure even flow distribution within a separating apparatus container.

A shower drain integrates a hydraulic drive system with a magnetic coupling to accelerate water outflow from wet rooms.

Segmenting airflow across two series valves prevents premature failure while a pressure indicator detects leakage to protect against corrosive gases.

Precharge voltage derived from measured gate terminal potential compensates transistor variations to eliminate insufficient writing in low tone regions.

A drain valve riser pipe uses a float-controlled venting device to release an air cushion, allowing liquid to enter and suddenly open the drain valve.

Merged liquid collection tank resolves space restrictions and stability issues by combining storage capacity with installation flexibility.
