Pipe Couplings TRIZ Cases

Segmented clamping and compensating elements reduce friction-induced contamination on moving assemblies while maintaining hermetic seals.

Angular coded mechanisms on aircraft pipes enable precise bending and tool-free assembly, eliminating custom wedging devices.

A plug-in pipe coupling uses a radially deformable retaining ring to engage grooves on the spigot for secure locking.

An axial control part verifies locking arm position by remaining attached only when fully engaged, enabling visual assembly confirmation.

A dual-latch quick connector uses a spring latch and sliding lock to secure fluid lines.

Fluorinated compounds and silicone oil diffuse to the inner pipe wall, forming a lubricating film that prevents biofilm formation and scaling.

Embedded RFID circuit leads contact the fluid connector to complete the circuit, resolving incomplete seating issues in confined automotive spaces.

Rotation restricting parts on the pipe joint prevent relative rotation, minimizing wear and leakage in vehicular air conditioners.

A reusable cap assembly with interconnected rubber covers protects multiple hydraulic ports from contamination.

A connector device uses a deformation zone to decouple locking projections from the sealing area for easy detachment.

A push-lock pipe coupling uses rigid fingers and circumferential grooves to create a secure mechanical connection between adjacent pipes.

A movement-constraining assembly secures fluid-conveying tubes using a blocking ring with complementary surfaces to prevent rotational unscrewing.

A female connector latch integrates spring arms with a release button to simplify assembly and secure fluid conduit coupling.

Anodized aluminum pneumatic couplers use color coding to visually identify compatible plug and sleeve pairs, preventing mismatched connections that cause leaks.

A crimping ring secures a plastic piping shield to join dissimilar metal sections without specialized tools.

Conductive dome detects nozzle snap-in to prevent engine overpressure and ensure emission compliance.

Inverting a calibration hose positions a liner while an expanded bladder secures a fastening device, eliminating specialized packers for varying pipe diameters.

A deformable U-shaped pin positions the male connector end before locking, preventing misalignment under pressure.

A coupler connection system uses a securement housing to shield the air brake interface from road debris and accidental separation.

L-shaped stay and specific protrusion dimensions prevent erroneous pipe assembly in electric rotary machine cooling systems.

An intermediary sleeve transfers axial fluid pressure to locking arms, maintaining seal integrity under high-pressure vibration and cyclic loading.

A tubular quick coupling uses a flexible divisible ring to lock fluid connections securely against accidental removal.

A breakaway assembly uses a relief valve to release trapped fluid pressure during separation.

A fluid coupling retainer uses locking arms to secure a male member within a throughbore.

A torque collar limits stroke on conduit fittings to enable consistent pull-up.

Outer chamfers displace radial stops on the clamping sleeve, preventing sealing ring displacement during plastic pipe insertion.
