Roof Drainage TRIZ Cases
- Multi-material-blade for active regenerative magnetocaloric or electro-caloric heat engines
See how stacked elements with varying Curie temperatures and dedicated channels reduce pressure
- Mailbox Post Protector with Internal Toolless Latch Assembly
See how internal latch chambers enable toolless assembly of segmented post protectors, conceali
- Multi-material-blade for active regenerative magneto-caloric or electro-caloric heat engines
See how segmented blades with graded porosity and material-specific Curie temperatures reduce p
- Multi-Material Regenerator Blades for Low-Loss Caloric Heat Engines
Segmented caloric regenerator blades with dedicated channels and hydrophobic coatings cut pressure loss and improve heat transfer in compact engines.
- Ramped Elbow Connection to Prevent Drainage Sediment Buildup
A 95° elbow with a ramped internal surface maintains water velocity through the bend to reduce sediment buildup and blockage.
- Modular Extendable Drainpipe Assembly for Length Adjustment and Reuse
Detachable adapters and an expandable pipe body let drainpipe length change without new molds while enabling part replacement and reuse.
- Pivoting Flexible Downspout Extension for Durable Storage
A semi-rigid rubber-like downspout extension pivots upward for storage while resisting crushing, wear, and fastener tear-through.
- Threaded Telescopic Drainpipe Assembly for Replaceable Connections
Separate threaded adapters and a spiral telescopic pipe cut replacement waste, lower drainpipe costs, and keep drainage length adjustable.
