Sewer Systems TRIZ Cases

A universal carrier interface lets sewer cameras and tools be swapped in place, avoiding system removal and cutting inspection downtime.

A transverse pan-tilt camera improves visibility of the guide tip in sewer branch inspection while reducing reflections and shaft interference.

A rotorcraft UAV captures images inside sewer pipes, avoiding toxic gas exposure and mobility limits from water-filled inspection routes.

Voice and gesture input replaces manual controls in sewer pipe inspection, enabling safer camera operation while operators keep protective gloves on.

Using wastewater flow instead of motors, this pipe inspection case stabilizes sonar or camera data to detect fouling and structural distortion.

Temperature sensors on a conductor strip verify drainage fill-level readings by detecting contamination and sedimentation that can cause false shorts.

A limiting structure lets the non-return portion be removed and repositioned easily while blocking insects and mice and preserving drainage.

Movable support rollers guide high-pressure hoses through pivot bearings, reducing friction and preventing slippage during 360-degree boom rotation.

Vertical axis suction reel maintains horizontal pipe orientation to eliminate pressure drops during pumping operations.

Differentiated shutter profiles prevent rodent passage and reduce organic matter accumulation in sewage pipes.

Integrating a telescopic test pipe into the housing eliminates separate leak testing equipment while maintaining reliable backflow prevention.

An automated road drain cleaning apparatus uses magnetic cover removal and suction to clear debris.

A backflow valve employs a bypass guide to position a floatable ball, preventing residue adhesion and ensuring reliable sealing.

An integrated hose reel and suction pipe assembly reduces vehicle complexity by using a guide arm to prevent twisting during operation.

A movable extension plate assembly uses hydraulic pusher force to distribute debris evenly in dump boxes, eliminating manual spreading labor.

Polyurethane connecting element compensates for angular errors to reduce vibration and wear.

A sewer cleaning vehicle boom pivots 220 degrees to guide suction and flushing hoses from separate reels.

Integrating a caisson cover lifter with a sludge trap cleaner automates road gully cleaning, eliminating manual labor and reducing operational time.

Rollers guide hoses along the vehicle axis, eliminating pivot bearing friction for a 270-degree working range.

An overbalancing member biases the valve closed to prevent backflow flutter while reducing clearance space requirements.

A sewer blockage detection system uses pressurized gas flow through a pipe opening to measure internal pressure changes.

Integrated lock members and brackets engage under force to prevent rat access while allowing waste flow.

Gravity-pivoted shutters in a sewage barrier prevent vermin entry without requiring professional installation or specific pipe dimensions.

A hinged gate prevents animal entry in drain pipes, opening automatically to clear debris and avoid flooding.
