Sealing Arrangements TRIZ Cases

Deformable U-shaped seals close sash-to-frame gaps to stop air leaks while keeping large sliding room openings easy to operate.

A geared trigger mechanism cuts the force needed to close a sliding door seal while overcoming return-spring resistance and keeping the door shut.

Layered lateral and vertical seals close gaps around an integrated wicket door to block water, air leakage, wind, and condensation.

A track-guided adjustment panel lets one pet door insert fit varied window or sliding door openings while maintaining a weather-tight seal.

Dual seals, a thermal break, and a protected rotary bearing help large pivot doors block driving rain and reduce heat transfer.

Rollers and ramp surfaces convert plunger motion into low-friction drop-plate sealing, cutting wear and closing door-floor gaps with less force.

A tension-triggered drop seal uses a spring-loaded slider to seal multi-part sliding doors and windows without major structural changes.

A self-aligning barrier closes the upper sliding door gap without movable strips, reducing friction, noise, and installation complexity.

A self-aligning bearing element seals the top door gap while cutting friction, noise, and adaptation effort across sliding door systems.

An adjustable base with dual seals and a brush closes sliding door or window gaps caused by floor unevenness while preserving smooth movement.

A suede-lined door groove and smooth outer surface keep the doorstop attached at the door edge while reducing carpet friction and storage bulk.

A carrier profile, adhesive joint, and tensioned strap replace a rigid sliding-door frame to cut material, assembly time, and cost.

A two-part mounting and sealing profile secures sliding door seals without door grooves, reducing moisture ingress, sound loss, and install time.

Flexible fabric hinges and laminate panel layers absorb forklift impacts while maintaining seals against water and air intrusion.

A necked seal with compressible legs and an internal cavity spreads flexing stress to prevent crushing, wear, and permanent set.

A frame projection converts sliding motion into drop-seal deployment, improving sealing while avoiding external actuators and high user resistance.

A flexible loop seal closes the ramp-side gap in dock levellers, blocking rodents while staying compact for storage and transport.

A rigid-flexible sealing plug keeps French window sash joints watertight without silicone, cutting installation time and tolerance sensitivity.

Reduced-section hinge regions let one gasket wrap window frame corners without thickness buildup, improving sealing and insulation.

Airtight members seal gaps between movable multi-layered glass sashes, enabling FIX-panel opening and a compact sash frame.

An extended lever in an automatic sliding-door seal lowers actuation force while the return spring resets the sealing strip.

Angled frame and door surfaces engage near closure, while rear and drop seals limit sound and air leakage.
