Vertical Ducts TRIZ Cases
- Light Well Cover Structure That Prevents Edge Dirt Buildup
An overhanging substructure lets dirt fall through around a light well cover, keeping visible edges clean while preserving secure support.
- Deck Drainage Clips and Tensioned Membrane Gutter Assembly
Clip-mounted rails tension a removable waterproof membrane into a hammock-like gutter that improves deck drainage and simplifies cleaning.
- Metal Roof Vent Cap With Rib Receiver for Pipe Misalignment
Rib intersections make metal-roof vent sealing labor-intensive; a rib receiver and lateral shoulders accommodate offset pipes while butyl tape seals the flange.
- Fiber-Reinforced Thermoplastic Modular Step for Window Well Egress
Detachable flanges and slots make durable window well egress steps lighter, easier to install, replace, and customize.
- Foamed Glass Separating Ring in Mantle Stone Chimney Systems
A mantle stone chimney block integrates a foamed glass separating ring to provide structural support and thermal insulation within the wall assembly.
- Folded Sheet Metal Floor Panel With Integrated Liquid Collection Channel
Segmented floor panels with pre-formed collection channels eliminate costly drainage adaptation while ensuring targeted liquid removal.
- Weld-Free Chute Door Assembly with External Automatic Closer
Extraction of linkage systems and direct-acting closers reduces contamination risks while maintaining reliable automatic closing.
- Cross-Laminated Timber Room Cell Duct Step Design
A duct floor step decouples stacked room cell utilities, resolving noise insulation and maintenance accessibility trade-offs.
- Light Well Body Locking Mechanism for Tool-Free Height Adjustment
A light well body locking element enables manual height adjustment by moving between release and engagement positions along a wall-mounted track.
- Modular Building Engineering Module with Heat Recovery
A modular building engineering module integrates ventilation and heat pumps into a prefabricated box structure for exterior wall mounting.
- Flue Gas Chimney With Nested PVDF Pipes For Condensing Heater Modernization
Nested PVDF pipes routed through receiving elements allow condensing heater exhaust integration without structural chimney modifications.
- Rafter Connector With Hollow Guide Element For Vertical Line Support
An internally hollow guide element in a rafter connector enhances bending stiffness and reduces installation space for supporting vertical lines like flues.
- Modular Fiber-Reinforced Thermoplastic Step for Window Well
Fiber reinforced thermoplastic steps replace heavy metal components, reducing weight while maintaining structural strength and corrosion resistance.
- Modular Window Well Insert Using Long Fiber Reinforced Plastic
Long fiber reinforced plastic inserts replace heavy metal wells, reducing weight while maintaining strength through omnidirectional fiber reinforcement.
- Side Wall Joint Box Electrical Wiring Structure
Relocating joint boxes to side walls eliminates ceiling work, reducing material waste and improving safety.
- Stackable Window Well Modules with Curved Sidewalls
Stackable window well modules use curved sidewalls and interlocking features to resist hydrostatic pressure while enabling quick assembly.
- Curved Sidewall Window Well with Integrated Ladder
Unitary curved sidewalls and integrated footholds provide structural rigidity while allowing soil uplift through an open bottom design.
- Modular Window Well Insert Using Long Fiber Reinforced Thermoplastic
Omnidirectional fibers in the composite material provide structural strength while segmentation allows damaged sections to be replaced without full excavation.
- Modular Light Ventilation Shaft With Interconnected Base And Side Modules
Segmented modular components with standardized connections resolve manufacturing complexity while enabling flexible shaft configurations.
- Light Shaft Body Projection for Drainage and Insulation
A light shaft body projection positions the drainage connection away from the flange to enable full perimeter insulation.
- Roof Outlet Removable Panel System for Aesthetic Customization
Segmented removable panels replace fixed coatings on the roof outlet side casing, resolving manufacturing efficiency versus aesthetic customization trade-offs.
- Light Well Extension Element with Hollow Profile
A light well extension element uses a hollow profile and detachable screw attachment to simplify assembly.
- Basement Light Shaft Mounting Device with Stiffening Webs
Stiffening webs reinforce the mounting device frame, eliminating prefabricated fastening points and enabling flexible positioning during basement installation.
