Sleeve/Socket Joints TRIZ Cases

Acid-treated graphite expands thermally while the embedded metal wire net provides rigidity, preventing permanent set in exhaust pipe joints.

A fluid line coupling uses a D-shaped sealing ring with a retaining collar to secure the seal against rotation.

Complementary keys on the tube support prevent collet misalignment, reducing O-ring damage risk.

Nested grip rings in a hybrid push-to-connect fitting resist rotational torque, solving the stability gap in standard push-fit piping connections.

A brazed bond layer with a semicircular pool space connects a connecting member to a terminal in a ceramic member.

Spinning impellers generate vacuum pressure to hold can lids, reducing mechanical wear and maintenance needs in sealant liner applicators.

Segmented elastomer design with sleeve rings prevents dirt ingress and reduces friction while distributing compressive stresses during maximum pressing forces.

Radial protrusions on the seal member inhibit fluid leakage after crimping, resolving the trade-off between assembly ease and seal reliability.

Rigid locking fingers engage male pipe grooves to prevent withdrawal without gluing or welding.

A fluid line connector uses a combined ferrule and sealing ring member to mechanically lock refrigerant lines while forming a tight seal.

Varying the radius of curvature along coupling segment surfaces reduces torque required to tighten fasteners while maintaining mechanical restraint.

A sintered alumina electrostatic chuck uses a carbon-graded support member to prevent niobium diffusion from the resistance heating body.

A flexible graduated collar connects large intake conduits to smaller turbocharger flanges.

A lightweight radiator nipple uses a toroidal seal and inclined chamfers to create a secure hydraulic connection between elements.

Flexible acrylic adhesive relieves thermal expansion stress between electrostatic chuck and cooling plate, preventing voids and dielectric breakdown.

An elastomeric sealing ring anchors inside a pipe bell to provide both fluid sealing and axial restraint without external clamps.

Rollers cold work pipe sidewalls to form shoulder, groove, and bead configurations that provide strong fluid-tight joints for thinner walled elements.

A clamping device with a rotating flange and spring member secures oscillating working elements without disengagement.

Differential support surface radii preserve elasticity during repeated assembly, preventing coupling strength loss from wear.

Integrated pipe guide system maintains axial alignment between connected pipes using a sliding shroud mechanism.
