Pipe-Joints TRIZ Cases

See how bendable side-arm levers with locking ridges enable secure pipe connections that discon

Elastic engagement fingers and an inclined surface enable quick hose locking while resisting traction, vibration, water, and dust.

Radially movable inserts lock a wear ring onto corrugated pipe without screws, reducing abrasion damage and speeding re-positioning.

Helical external threads let a tube insert screw into and out of a housing, preserving secure anchoring while enabling gasket-safe removal.

Angled internal clips and barbs secure corrugated conduit to a coupler while maintaining fluid communication and preventing separation.

A one-piece slotted locking ring and film hinge secure corrugated pipes with lower assembly complexity, lower cost, and non-destructive locking.

A pivoting coupling element with elastic return secures ventilation hoses quickly while improving sealing and reducing air leakage.

Elastic clip teeth lock a corrugated conduit against pullout while an internal seal blocks contamination under vibration and water hammer.

Ratcheting teeth and resilient arms seal aligned post-tensioning ducts against grout while speeding precast concrete connection.

A grounded conductive resin rod with a central hollow removes charge from pipe-flow centers while keeping pressure loss low.

Elastic collet clamping and a sealing element let one hose connector fit multiple line diameters without sacrificing hold or seal.

Oblique interlocking teeth join composite tubular shells without radial fasteners, reducing stress, leakage risk, and internal flow disruption.

Integrated ribs, sealing features, and anti-twist locking let corrugated pipes connect tightly in a compact screw fastening without extra seals.

A compressible conductive disc creates a reliable charge path between plug and coupling parts without costly conductive O-rings or greases.

An insulating washer isolates dissimilar metal pipes in a compact coupling, preventing galvanic corrosion and leakage.

A push-fit joint combined with an electrowelding sleeve improves pipe sealing above 5 bar while simplifying alignment and assembly.

A ribbed coupler and retaining collar join dissimilar geothermal pipes without hot or wet work, creating a watertight seal that resists thermal cycling.

Cantilevered detents and slotted sleeve sections let one connector grip pipes of different diameters while simplifying molding and assembly.

A threaded closure plug and gasket seal post-tension duct ends, blocking air and water intrusion while preserving complete grout flow.

An integrated pawl-support retainer shortens flexible pipe insertion while maintaining firm engagement and sealing in corrugated pipe joints.

A flexible bellows seal with pressure cylinders compensates for pipe offset and anti-parallelism to maintain airtight granular conveyor connections.

A gasketed closure load plug seals post-tension duct joints to stop epoxy leakage, block air and water intrusion, and enable complete grouting.

Interchangeable threaded fitments match tubing diameters to keep connections fluid-tight, resist kinking, and reduce contamination.

A deformable connector links pawls and supports so a corrugated pipe locks securely with shorter insertion and no extra member motion.

A rotating locking part drives a resilient engaging element into hose corrugations to prevent leaks, accidental disconnection, and support automated assembly.
