Pipe Elements TRIZ Cases

Dual toothed rows with spring-loaded pinions distribute locking force to maintain permanent contact with the pipe wall.

A line plug uses a single actuator to grip the inner surface before compressing the seal.

A flexible element reinforces ductile pipes for composite extraction, resolving tensile failure during removal.

A liner assembly restricts longitudinal stretching with a non-stretchable strap inside an inflatable bladder, preventing weak regions in repaired pipelines.

Segmented repair fittings with expandable seals resolve sealing gaps in thick-walled pipes by dynamically adjusting outer diameter.

Composite steel wire and textile braid layers resolve the trade-off between burst pressure and fatigue life in hydraulic expansion hoses.

A thermoplastic fluoropolymer pipe liner expands to fit metal pipelines, ensuring long-term stability and resistance to corrosive materials.

Sight gauge assembly merges filling, draining, and sampling into one housing opening to minimize leak risks.

A quick connect adaptor system enables versatile fluid device attachment through dual interface design.

An internal accordion tube seals the seam while a turbulence coil decelerates fluid flow to prevent combustion.

Segmented fastener prevents cover distortion during transport by enabling temporary preassembly and accurate pipe alignment.

Segmented inflatable bladders and push-pull-turn hoses enable liner installation in pipes under 35 mm diameter.

A pipe fastening device uses a conical flexible connecting element to suspend the fixing clamp from the bearing clamp.

Relocating the hinge to an elevated angular position resolves the conflict between maintaining a compact semi-circular shape and achieving easy lid access.

A hydropneumatic bladder accumulator uses a support body to shield the flexible separating diaphragm from mechanical stress.

Axial engagement of a slip ring with a canister groove eliminates manual threading, resolving time-consuming attachment processes.

A tear-resistant protective tube surrounds a UV-impermeable tubular liner to enable smooth pulling into sewers without folding.

Encasing a valved fitting with settable sealing material prevents corrosion and leaks, enabling service pipe maintenance without shutting off mains flow.

Pre-curving the profile strip to the target radius eliminates restoring forces that expand pipe diameter and increase friction during insertion.

Locating pins engage honeycomb ribs to prevent core spinning and ensure uniform web tension.

Segmenting the tube into low-resistance elastomer and high-resistance fiberglass sections reduces weight while maintaining lightning strike protection.

A quick-acting coupling integrates a sliding locking device with a safety mechanism for secure pipeline connections.

An internal pipe cutter uses a motor-driven blade to slice damaged valve box sections from within existing structures.

An adapter lowers the air tank relative to the rifle body to clear scope alignment paths.

A rotating scraper blade prevents polymer deposits on the reactor wall to maintain heat transfer and control molecular weight distribution.

Wedge-driven legs expand within the shaft bore to engage internal projections, maintaining a tight seal under high oil pressure and temperature.

Pressure dampers isolate the immersion liquid from acceleration-induced fluctuations, preventing substrate deformation and maintaining overlay precision.

Carbon nanotube dispersion in the valve element conducts static charges to ground, preventing resin breakdown and fluid contamination.
