Joints With Sealing Surfaces TRIZ Cases
- Halogenated Carbonate Electrolyte for Lithium Battery Cycle Life
Fluorinated cyclic carbonates mediate anode reactions to prevent dendrite formation and improve cycle life in high-capacity lithium secondary batteries.
- Flexible Hose Coupling Nut Mounting Without Welding
A flexible hose coupling nut mounts via a clamping sleeve and support sleeve to secure the braiding without welding.
- Self-Locking Plug With Flexible Beam Fingers
Flexible beam fingers travel across detents during rotation to prevent loosening in aircraft borescope ports while eliminating the need for special tools.
- Energy-Dissipative Corrugated Tubing for Lightning Protection
Composite corrugated tubing with conductive and insulative resin layers absorbs lightning currents to prevent flashovers in piping systems.
- Tapered Conduit Interconnection for Molten Polymer Melt Trains
Tapered interlocking features force interface surfaces together, preventing re-solidification and specks caused by alignment mismatches in melt trains.
- Notched Ferrule Elastic Deformation for High-Pressure Sealing
A notched ferrule bends elastically to grip hard tubing and form a secure seal without extra components.
- Tube Connector Assembly with Bend Relief Nut for Stress Distribution
A tube connector assembly uses a nut with a bend relief portion to distribute stress along the tube length.
- Exhaust Joint Engagement With Projections And Recesses
An exhaust joint with an engagement member connects directly to tube projections and recesses.
- Axial Swage Fluid Fitting for Soft Tubing
A fluid fitting uses axial swaging to secure soft tubing with cylindrical sleeves.
- Annular Electrode Element With Sealing Elements For Fluid Systems
Sealing elements secure an annular electrode for easy removal without deposit flaking, preventing line blockages.
- Axial Swaged Fitting Elastic Strain Preload
Axial swaged fitting deforms compression balls via a collar to establish an elastic strain preload, resisting vibration-induced connection failure.
- Electro-fusion Pipe Coupling with Plastic Liner for Corrosion Resistance
An electro-fusion assembly joins lined pipes while a clamp system limits movement during construction.
- One-Piece Nozzle With Integrated Frustoconical Seal
A one-piece nozzle integrates a frustoconical sealing member directly into the coupling piece to eliminate loose components.
- Sequential Sealing Fitting with Restoring Load
A fitting design uses a swage ring to sequentially set three seals, maintaining optimal sealing force throughout the installation process.
- Threaded Plug with Displaceable Flange for Hammer Union Thread Protection
A threaded plug with a displaceable flange protects hammer union threads and sealing surfaces during handling.
- Plastic Pipe Union Integral Locking Structure Vibration Loosening
Scalloped engagement surfaces on the nut and tail piece interact with a compressing elastomeric ring to prevent loosening under vibration.
- Pipe Connecting Device With Flared Inner Ring And Inclined Pressing Surface
An inclined union nut pressing portion distributes pressure against a flared inner ring surface, reducing component stress while maintaining seal reliability.
- Tube Coupling Joint With Press-Fitted Ring For Sealing
A tube coupling joint uses a press-fitted ring to flare the tube end for secure fixation.
- Retaining Member Radial Release for Ferrule Assembly
Nested retaining members release ferrules radially to simplify assembly while maintaining fluid-tight seals.
- Hammer Union Metal Gasket Retention via Asymmetric Flange
An asymmetric gasket flange interlocks with a pipe receiving portion to prevent vertical displacement, resolving retention issues in hammer unions.
