Joints With Sealing Surfaces TRIZ Cases
- Compression Pipe Fitting Structure for Wide-Diameter Gasket Sealing
A blocking member and segmented support body keep the gasket loaded and the pipe restrained across varying pipe diameters.
- Metal Garden Hose Strain-Relief Assembly for Sharp-Angle Pulling
A flexible strain-relief section at the faucet end redirects pulling forces to prevent kinking, shell damage, and inner tube exposure.
- Pipeline Cutting Ring Seal Geometry for Vibration-Resistant Sealing
A grooved cutting ring with a rounded conical seal seat prevents elastomer extrusion and damage when pipeline joints loosen under vibration.
- Tapered Pipe Screw Connection to Prevent Over-Tightening Leaks
A tapered thread and complementary union nut cut installation turns while balancing radial forces to prevent cone damage and leakage.
- Corrugated Tube Connector With Tapered Braid Locking Under Pressure
Projections between tapered inner and outer sleeves create a narrow braid-holding region that resists high pressure and prevents tube damage.
- Telescopic Catheter Coupling Ring for Secure Extension Locking
A displaceable coupling ring locks nested catheter tubes during use while allowing compact storage, reducing collapse and anatomical damage risk.
- Thick-Walled Tube Fitting With Flared Bite-Seal Connection
A single flaring and sleeve-deformation step creates a biting, multi-point seal on thick-walled tubes for vibration-resistant assembly.
- Hose Connector Assembly That Seals Without Twisting the Hose
A ring nut and pressure element compress the hose onto a spigot for a secure seal while preventing twist and easing assembly on extendible hoses.
