Pipes TRIZ Cases

Compressed composite fire protection profiles ease insertion into building openings, then expand to form a tight fire seal.

Aligned layered blowing-agent particles steer fire-driven expansion into passage openings, speeding closure while limiting lateral push-out.

A two-part rosette compensates for angled intermediate pipes so the outlet stays flush to the wall while preserving drainage and insulation.

Compressed composite fire protection profiles expand after insertion to fit irregular openings and maintain smoke- and flame-tight seals.

A two-part outer diameter extender lets one cylindrical seal fit more opening sizes, cutting seal stock variety while maintaining sealing.

A reversible housing, funnel drain path, and elastomeric gasket add flexible condensate drainage while reducing appliance noise and vibration.

An expandable graphite coating on a framed pipe filler speeds blockage under heat while improving adhesion and limiting fire and toxic gas spread.

A fusible-release shutter keeps wall penetrations open for zone pressure balance and flooding, then closes under heat to delay fire spread.

Modular bulkhead connectors and grommets create fluid-tight spa jet pack connections that cut leak points and simplify installation and repair.

A compressible connector body and nested conductor path adapt to cable diameters while improving grounding, sealing, and damage resistance.

A reflective mesh wrap with adjustable straps covers floor penetrations around pipes, blocking debris while keeping dropped items retrievable.

A hinged split fire stop wraps around existing pipes in concrete floors, improving retrofit installation and smoke and heat sealing.

A stretchable sealing sheet with a preformed through hole and broad release-sheet coverage seals around protrusions to reduce air and moisture leakage.

Cleaning fluid flows over both inner and outer valve surfaces, enabling in-place sanitization without removal while preserving seal integrity.

A hinged fold-out collar and spring-actuated fire-resistant cap seal plastic pipe penetrations in retrofits where access is limited.

An elastic ribbed plug with hingeable surfaces uses pressure differential to keep conduit sleeve seals tight without frequent retightening.

Mechanical compression seals replace adhesives in sump wall penetration fittings, cutting leaks, maintenance, and retrofit effort.

An intermediary threaded fastener with O-ring clamping keeps a rectangular wall rosette aligned, rotation-secure, and sealed on sanitary fittings.

A hollow body cast against formwork creates an axial cavity for angled feedthroughs, simplifying cable routing and sealing in concrete walls or floors.

Radially spaced elastic ribs let one sealing mat fit different pipe diameters and shapes, then swell on liquid contact for a lasting seal.

Combines pipe isolation and nail shielding in one stud-bore insert, cutting parts, install time, and inspection risk.

Pre-integrating a movable fire protection insert into formwork enables immediate opening sealing after casting while allowing post-cast position adjustment.

A heat-driven firestop insert is cast into walls or ceilings, then moves outward in a fire to close openings early and reliably.

Pre-angled hubs and bends simplify cleanroom pipe installation, preserve pipe integrity, and maintain drainage slopes with less labor.

A protrusion block on the pool outlet valve keeps users off the drainage surface, reducing suction entrapment while preserving water drainage.

A threaded wall-pass sealing joint uses stainless steel and carbon-graphite gaskets to keep ducts watertight after fire exposure.

An elastic sealing lip provides the initial smoke seal, while heat-activated intumescent expansion maintains fire sealing with less material.

A mesh-backed adhesive pipe covering seals wall gaps around pipes, blocking rodent entry while allowing quick diameter sizing.

A split plate slides behind a loose hose bib or spigot to restore secure wall mounting without fixture removal or pipe damage.

A single wall-passing multi-lumen conduit separates air and water flow to improve live bait oxygenation, waste removal, and setup ease.

Expanding barbs secure a firefighting accessory through a bulkhead aperture, delivering agent into sealed compartments without manual hose holding.

A detachable mounting plate and container let fire-resistant members be replaced without damaging walls or floors, improving maintenance and fit.

Bent torsion spring legs and stainless steel gauze help a fire collar block smoke and heat faster in thinner concrete walls.

A galvanized wire mesh casing retains the intumescent ring, enabling one fire stop assembly for metal or plastic penetrants under fire and water spray.

Composite fire protection profiles bond during fire, cutting sealing units and installation effort while maintaining fire resistance at lower density.

A thin metal sheath with intumescent lining forms a one-piece fire collar that fits varied pipe openings and seals fire and smoke in heat.

Stepped collar segments with intumescent layers fit different pipe diameters using one modular design while reducing material use and cost.

A separate, radially deformable sealing element lets installers seal pipes at varied diameters and angles without torque-critical elastomer clamping.

Mechanical compression seals replace adhesives in sump penetration fittings, improving liquid-tight sealing, durability, and installation speed.

A multi-passage mask with sleeves and a peripheral gasket speeds pipe bundle wall installation while preventing water ingress.

A mechanically joined inner, intermediate, and outer ferrule avoids weld cracking, resists thermal stress, and extends duct service life.

A two-stage PVC and expandable graphite formulation uses bio-based plasticizers to balance pipe collar fire resistance, mechanical properties, and lower toxic emissions.

A one-end-fixed sheet metal strip and hook lock let thicker firestop collars resist intumescent swelling while keeping the duct sealed.

A nested bracket hidden by the hydrant head conceals screws, blocks water ingress, and protects wood from rot.

Segmented compression seals create a liquid-tight sump wall and pipe fitting without adhesives, cutting installation time and seal uncertainty.

Segmented rings and gaskets create a liquid-tight sump pipe seal without adhesives or excavation, improving durability in hydrocarbon exposure.

A one-piece hose stop uses hose deformation and offset channels to prevent slipping while allowing quick repositioning without disassembly.

Profiles filled with intumescent material expand into adjacent sections during fire, cutting installation complexity while maintaining sealing.
