Watercraft Hull Design TRIZ Cases
- Tunnel Venturi U-Shaped Channels for Pontoon Boat Drag Reduction
Rear-facing U-shaped vents generate bubbling effects that reduce drag and improve speed without clogging from forward water flow.
- Ship Micro-bubble Generator Wing Air Supply
A ship micro-bubble generator uses a hull wing and air compressor to produce bubbles via Kelvin-Helmholtz instability.
- Structured Surfaces with Fluid-Support Structures for Flow Control
Wells communicate with fluid-support structures to stabilize pressure and prevent air bubble formation in microfluidic channels.
- Angled Keel Air Cushion Hull Drag Reduction
Angled keels generate an air cushion along outboard walls, reducing drag by 20% to 45% and improving stability in rough water.
- Stabilized Step Hull With Ventilated Tunnel For Drag Reduction
Segmented hull design with vertical sidewalls resolves the drag versus directional stability trade-off in planing vessels.
- Microbubble Generator for Ship Hull Friction Reduction
A microbubble generator creates negative pressure via a wing to draw air into water, reducing hull friction without requiring specific hull shapes.
- Ship Roll Stabilisation via Dynamic Damping Element Orientation
A rotatable damping element extends from a ship hull below the water line to actively stabilise roll motion during sailing.
- Marine Vessel Pontoon Strake Configuration for High-Speed Turn Stability
Three-pontoon floatation system with asymmetric strakes redirects water flow to enhance marine vessel handling.
- Boat Interceptor Guiding Arrangement for Force Distribution
A boat interceptor guiding arrangement absorbs hydrodynamic forces through rolling members and toothed wheels.
