Couplings TRIZ Cases

A connecting element uses a non-circular mandrel and rotatable ring sleeve to secure flexible tubes.

An axial relief ring manages overpressure in small-diameter couplings by shifting positions, avoiding the need for larger external beads.

Segmented recesses in the support saddle enable selective attachment methods, resolving the trade-off between connection reliability and flexibility of use.

Pre-assembling the clamping sleeve on the connector eliminates separate fitting steps and prevents cross-sectional narrowing.

Decompression means and mechanical blocking means in a compact cartridge coupling reduce operating loads and prevent involuntary closure.

Segmented come-off preventing legs prevent retainer instability during midway pipe insertion.

Optimized sleeve inclination angle increases distance to locking position, preventing accidental disconnection from rearward impacts.

Electric pump module pressurizes tank to force liquid through spray nozzle while switch assembly prevents over-pressurization.

A single cylindrical packing integrates body, plug, and valve sealing portions within a pipe joint assembly to reduce component count.

An elastically deformable safety ring transitions configurations to block or allow projecting part passage in pipe connections.

Asymmetric collars on a pre-assembled holding part prevent loss while enabling simple disassembly of fluid line connections.

A fluid connector uses a bellows sleeve to actuate connection without coil springs.

Nested elastic legs allow radial release operation, preventing accidental disengagement in confined automotive fluid pipe assemblies.

A latching connector design featuring a pressure locking sleeve and pre-sealing mechanism for secure fluid system attachment.

Radial nesting of sprags inside rollers secures high torque capacity without increasing the axial dimension of the drive input-switching mechanism.

Punched grip ring teeth prevent rotation and ensure electric continuity without complex rolling equipment or loss of seal.

Moveable members on engaging ramps reduce deformation by distributing forces across three-dimensional contact surfaces under high pressure.

A high-pressure hose fitting uses a flange ring and half shells to create a compact axial connection.

Segmented metal and plastic components maintain tightness across temperature variations without complex overmolding.

Segmented groove retains male part in unlocked position, preventing accidental separation.

A female pipe coupling sleeve displaces to receive a locking element in an outer through-hole, minimizing the component's external profile.

Segmented connector bodies with nested plug elements resolve volume constraints in cramped vehicle systems while maintaining fluid tight reliability.

Decompression means moderate internal pressure while a 3:1 hydraulic unbalancing system reduces coupling loads.

A pipe coupling uses a resilient biasing member to axially move a clamp ring into a locking position for immediate engagement.

A fluid line connection device uses a dial to strain a securing clip for rapid coupling.

A connector system uses lateral insertion and elastic deformation to join hydraulic pipes without threading.

A polymeric retaining clip secures a duct cuff to an automotive port using inward struts that hold the assembly without tools.

Self-sealing valves inside the coupling prevent fluid leakage and backflow when disconnected, ensuring patient safety during medical fluid delivery.

A single locking pawl merges two pairs of bodies to resolve complexity and strength trade-offs in quick couplings.

Segmented fitting design eliminates turbulence and pressure drops by separating structural support from sealing functions.
