Couplings TRIZ Cases

Elastic pins and an O-ring create a snap-fit cooling pipe connection that removes screws, cuts assembly effort, and maintains leak-proof retention.

A cam-driven coupling synchronizes connection, charging, and vent or recirculation states to simplify safe transfer of pressurized fluids.

An annular-gap locking housing with resilient holding portions enables tool-free fluid line assembly with secure alignment, strength, and leak-tightness.

Directing riser tension and compression into the conductor cuts wellhead load concentration, improving subsea assembly reliability and safety.

A poppet valve with shaped apertures uses surface tension to retain fluid during coupling disconnection while limiting air ingress.

Internal valves and secondary passageways let LRUs be swapped without full draining, refilling, or air bleeding in fluid systems.

A spring-biased valve and air path pull residual ink back during cartridge removal, suppressing leakage at the connection section.

An elastic threaded fastening body seals and locks a fluid line in a carrier opening while compensating for tolerances and simplifying assembly.

A self-closing seal and simple locking features contain waste fluid during uncoupling, minimizing outer-surface contamination in medical appliances.

A ring with an axial recess locks the connector element in place, enabling fast tool-free plugging and secure retention in tight spaces.

A cam-driven coupling synchronizes venting, re-circulation, and charge states to make high-pressure fluid transfer safer and more compact.

A separate gasket, rigid ring, and elastic tongues cut coupling cost while preserving sealing quality and secure male-female engagement.

Piezoelectric or bimetallic actuators rotate sprags directly, simplifying clutch engagement at target speeds while reducing friction and wear.

A pressurized piston and return mechanism automate male-female fluid coupling, cutting manual effort while maintaining secure locking.

A plug-style fitting joins mold fluid ports in one gesture, cutting heat-transfer conduit setup time during blow-molding mold changes.

Radial fastening sectors and a circular fulcrum let this quick pipe coupling hold high pressure yet release easily without tools or seizure.

Elastic locking arcs create a quasi-rigid media-line connection that handles heat, pressure, and positional deviation while enabling simple release.

A recessed annular bead contains molding flash below the end face, protecting seals and reducing false negatives in pressure testing.

A two-stage cam-lock lever keeps tubular couplers partially engaged during unlocking, venting internal pressure before full release.

Indexed locating features and a snap-fit retainer let a quick connect collar rotate for setup, then lock against stem rotation.

A release pusher and fastening ring let push-fit pipe joints be disconnected and reused without damaging seals or pipe.

A tapered guide member expands the wire retainer over a plain flange while a holding recess prevents unintended movement and connection failure.

A collet retainer and seal device create a single-push conduit connection that grips securely and stays leak-tight under pressure.

Equalized valve sleeve surfaces cancel pressure force, enabling effortless manual hydraulic coupling without depressurization.

Contact slopes and a sliding bar let the retaining clip engage securely while greatly reducing fluid line coupling insertion force.

A segmented gripper and multi-compression stiffener let stab-type pipe fittings stay removable while maintaining leak-proof seals across pipe and temperature variation.

Annular grooves, seal elements, and flexible retaining tabs improve pipe sealing and retention across varying conduit lengths and surfaces.

By moving the torsion spring to the clutch weight's distal end, this case maintains clutch capacity with lower spring force and a smaller clutch.

A terminal-ring and flange layout lets the seal and locking clip share one axial region, cutting quick connector coupling height.

A retractable stop blocks unchamfered tube ends and uses the chamfer as a cam, preventing seal damage and leakage in fluid connections.

Non-threaded brazed inlet connectors let one oxy-fuel torch fit country-specific quick couplings while reducing damage and design complexity.

A depth-limited tubular body, direct-contact seal, and locking portion cut backflow during disconnection while maintaining secure medical connector engagement.

Pre-mounted internal retainers create a push-lock pipe joint that prevents lost splines and speeds assembly and release.

An elastically pivotable lever and hooded locking claw keep a male luer securely engaged under external force while allowing easy release.

Multiple connecting webs stabilize holding teeth to raise media-line retention while keeping feedthrough insertion force low.

Shiftable elastic valve elements open during syringe insertion and reseal on withdrawal to prevent drug loss, leakage, and soiling.

A slidable collar, single spring, and one dynamic seal enable one-handed fluid-line connection and disconnection with fewer parts.

A spring-biased slider and recessed locking sleeve let locking balls engage securely during nipple insertion, preventing mis-latch in breathing couplings.

An irreversible bayonet groove and stud layout strengthens modular duct coupling against axial forces while keeping assembly simple.

Decoupling force closes the seal sleeve over passageways despite dried residue, preventing leakage and contamination in hollow-body couplings.

Tapered snap hooks and an integrated coupling ring improve locking stability, restoring force, and assembly simplicity in hose connectors.

A tapered tubular guide, seal element, and flexible retaining tabs help align pipe insertion, secure the connection, and prevent leakage and egress.

A spacing element bridges tube-wall indentation so the seal sits on undeformed pipe surface, improving sealing durability and reducing gas permeation.

A one-piece hose holder and captive pressure nut simplify assembly, prevent part loss, and keep water-stop flow working in either direction.

An integrated snap-hook, coupling-ring, and spring assembly improves quick connector locking stability while reducing parts and assembly effort.
