Sealing Arrangements TRIZ Cases

A modular trigger system converts door seals between hinge-side and lock-side releases using interchangeable stop surfaces.

Alternating teeth on retention clips mechanically constrain thermoplastic weatherstrips, preventing lengthwise shrinkage and preserving tight seals.

Angled guide posts maintain weatherstripping fiber orientation to prevent collapse and preserve long-term seal effectiveness against drafts.

A door hole seal uses a dual slit mechanism to manage wire harness extraction.

An asymmetric window seal design with a tapered head and foot structure minimizes curling under shear stress while maintaining reliable sealing forces.

A fenestration floating seal transitions between compressed and relaxed configurations to manage friction forces during sash movement.

Segmented flexible sealing strips prevent weapon misuse by breaking into short pieces, ensuring safety while maintaining effective noise and air abatement.

A plastic window center seal uses a stiff retaining plate and soft foamed EPDM profile to create an effective barrier.

Roller bearing guides channel longitudinal forces into the roller part, preventing jamming in heavy sash window applications.

Self-retaining corner pockets secure the seal without tools, preventing air leaks while allowing smooth door operation.

Triangular end profile integrates floor seal and cable routing, eliminating tripping hazards while maintaining universal panel compatibility.

A notched door channel frame releases excess material during bending to prevent surface wrinkles and maintain airtightness.

Transverse cuts divide the seal lip into independent segments that deflect over irregular floors, reducing friction and maintaining insulation.

A weatherstrip uses a compressible ethylene vinyl acetate bead to secure itself within a T-slot.

A pivot door seal triggering module uses a guided rotation element to actuate the drop-down seal housing profile rail.

Segmented rolling and transverse mechanisms enable intermediate locking and reliable sealing, reducing hardware complexity and improving aesthetics.

Deformable lip seals adapt to gaps between the sliding sash and frame, preventing air leaks while maintaining smooth operation.

A dual EPDM sealing strip uses distinct foam densities to provide mechanical strength and thermal resistance.

Soft thermoplastic elastomer bulbs bend around sharp corners without bulging, enabling recyclability and continuous sealing.

A passive window frame uses a metal cover surrounding bonded polyurethane foam insulation to achieve high thermal efficiency.

Segmented backing members with alignment structures connect to form a continuous seal, resolving transport and storage bottlenecks of long continuous designs.

A sliding door assembly uses a sealing plate to establish interfaces between the wagon and sill, reducing bottom height for wheelchair access.

Segmented seal extensions bridge gaps at loading dock door top corners, preventing air infiltration caused by blade seal deflection away from track assemblies.

A sliding door vertical seal uses a release element to actuate a sealing strip against a stationary activation unit.

A door seal housing protrudes into the hinge-side gap to position a sealing profile against the frame.

A sliding door seal assembly uses a weatherstrip and actuator to create a tight barrier between movable and fixed parts.

A magnetic door seal uses a batten bar and link arms to convert horizontal attraction into vertical movement for the sealing strip.

Integrated spring elements clamp glass blocks against a contact edge, compensating for production tolerances and eliminating the need for adhesive gluing.

Sliding supports on the sealing profile's support wall reduce friction and stiffness, eliminating manual adhesive application and simplifying installation.

An adjustable activation unit moves a sealing strip to seal sliding doors.

A door bottom security strip uses a deflecting element to block tool insertion.

Extruded rail overhead door secures glazing panels via protruding portions, resisting external impacts and maintaining structural integrity.

A rotatable magnet on the door leaf reduces operating force by alternating magnetic attraction and repulsion against a fixed magnet on the sealing strip.

A sealing device uses a retaining profile receptacle to mechanically engage the sealing profile.

Sliding profiles allow quick length adjustment without damaging the actuation mechanism, reducing inventory costs.
