Condensed Water Drain-Off TRIZ Cases

A sealed gutter and braided drain wire capture window condensation and route it to a collector before water damages frames or fittings.

A passive siphon tube drains sliding door and window tracks during wind-driven rain, improving drainage when weep holes are overwhelmed.

Selective hydrophobic and hydrophilic regions guide water through fenestration frame flow paths while blocking ingress into dry areas.

Localized hydrophobic and hydrophilic regions on fenestration profiles steer water to drain paths while maintaining sealing and pressure equalization.

Built-in perimeter drainage channels, weep holes, and wicking paths move water out of window and door frames to prevent hidden buildup and damage.

Intermediate water caps and a threshold dewatering plate channel moisture out of sectional door panels while preserving appearance and blocking ingress.

A frame-mounted water-guidance element collects and drains water below the lower hinge to stop rebate-seal interruptions from causing ingress.

Sheet metal drain screening uses adjustable slots and large openings to block debris, fit varied window sizes, and reduce clogging.

Traditional weep holes can clog and mar frame profiles; a top water channel and wicking layer route water to the exterior.

Positive coupling and a sealing film intercept driving rain, creating a second water-guiding plane for facade protection.

Segmented frame, cover plate, and elongate body allow targeted repair of damaged sections while maintaining water drainage and sealing performance.

Transverse through channels in the window frame bottom element direct condensed water to an external throating outlet.

An integrated foil layer under the window sill directs water to a drip zone, preventing penetration behind the outside wall.

Lockable positioning accessory guides sealing agent expansion in hollow posts, eliminating foam cavities and ensuring watertight compartment separation.

Interlocking corner joints eliminate visible mitred seams, and thermal break elements prevent heat transfer between PVC frames and aluminum covers.

A sliding door guide rail uses a hollow chamber to collect and drain precipitation through hidden openings.

A weatherboard holder uses a hook-shaped element to anchor into frame water slots while a circular joint allows rotational adjustment.

Integrating weep holes into tapered door sill towers removes moisture while eliminating separate collection pans and reducing manufacturing complexity.

Integrated drainage channels in hollow profiles remove moisture from cavities, preventing thermal bridges that degrade insulation over time.

Vertical housing gaskets prevent capillary moisture infiltration in enclosure rails by spanning the entire joint length.

Merged threshold and drainage channel eliminate trade coordination complexity while ensuring reliable surface water removal in barrier-free installations.

A fenestration frame glazing stop features a releasable coupling mechanism for interior component access.

A movable lift rail assembly with a seal retaining channel engages a sill flange to secure the window frame.

A drainable threshold uses a water ramp member to channel liquid through apertures in the trough section.

Exterior shingling seals bound vertical channels that drain seepage via a vent, preventing blowing rain from breaching interior seals.

A hollow threshold profile with a flat upper surface and internal drainage chamber simplifies sliding door assembly.

Interchangeable sill components and connection elements enable flexible guide configuration for sliding doors without complex screed integration.

Creating drainage holes in loose partitions before assembly eliminates visible exterior openings and prevents tool breakage during wide profile machining.

A closed water pipe drains rainwater by gravity from a collection chamber into a wind-sheltered outlet, preventing backflow during storms.

Segmented drainage tray adapts to varying transverse element dimensions, preventing water stagnation and air infiltration in sliding doors.
