Vessel Safety TRIZ Cases
- Dual Telescoping Lightning Diverter for Wind-Stable Mast Extension
A concentric dual telescoping mast extends only under lightning risk, improving wind stability while maintaining grounded strike diversion.
- Telescopic Lightning Diverter Rod for Watercraft Wind Resistance
Sensors extend a telescopic lightning rod only during storm conditions, diverting strikes from watercraft while limiting wind load.
- Rotatable Liquid Column Tank for Directional Vibration Damping
A rotatable multi-column tank aligns discrete natural frequencies with vibration direction to widen tuning range and improve damping.
- Closed Liquid Tank Trim Control for Ballast-Free Transport Ships
Internal liquid transfer between closed tanks maintains ship trim and draught without seawater ballast, improving stability and port maneuvering.
- Under Keel Ballast Tank for Floating Platform Payload Expansion
Adding ballast below the keel lowers center of gravity, boosting floating platform payload and stability without dry docking.
- Marine Hose Boom Safety Stop With Articulating Cradle Arrest
A passive articulating cradle intercepts a falling marine hose boom, absorbs impact energy, and reduces injury, damage, and spark risk.
- Detachable Canoe Stabilizer Floats With Adjustable Gunwale Clamps
Lightweight detachable floats and adjustable gunwale clamps stabilize canoes against capsizing without tools while staying portable.
- Inflatable Salvage Bag for Irregular-Hole Flow Reduction
Pressurized gas expands a reinforced inner bag to conform to irregular hull or tank holes, reducing flow with less handling force.
- Floating Wind Turbine Platform Ballast Redistribution for Tilt Control
Sensors trigger pump-driven ballast redistribution between pontoons to keep a floating wind platform within a predefined tilt range.
- Marine Emergency Airbag Flotation for Rapid Vessel Stabilization
Pre-installed airbags, compressed-air tanks, and automatic sensors help stabilize boats quickly during capsizing, submersion, or flooding.
- Ship Compartment Flooding Measurement with Multi-Zone Float Sensors
Multiple float sensors combine local water-height readings to compensate for ship movement and estimate time to critical flooding.
- Multihull Righting Mechanism Using Selective Liquid Ballast
Strong winds and kite tension can capsize multihulls; selective liquid ballast and displacement restore stable operation.
- Modular Buoyancy Can Assembly for Spar Crane Installation
Bolted modular compartments fit a spar’s vacant slot, adding buoyancy without the derrick barge required for long cans.
- Safe Under Keel Clearance Calculation for Ultra-Large Ships
Dynamic squat force analysis replaces static experience values to determine safe under keel clearance, preventing navigation hazards in shallow water.
- Movable Sponson Stabilization for High-Speed Watercraft
Movable sponsons coupled with struts and shock absorbers dampen wave impacts, maintaining propeller immersion during high-speed turns.
- Reconfigurable Multihull Vessel Pin Connectors
Pin connectors join moveable planar platforms to longitudinal hulls for modular floating vessel assembly.
- Modular UUV Center of Mass Adjustment via Magnetic Segmentation
A modular unmanned underwater vehicle adjusts its center of mass using magnetic attachments to enable in-field configuration.
- Ship Roll Vibration Detection via Heave Phase Analysis
Segmenting roll angle measurements into ascending and descending heave phases enables early vibration detection without continuous complex processing.
- Outboard Stabilizer Foam Core with Non-Compressive Inflatable Bladder
Inelastic joining members prevent inflated bladder from compressing foam core, preserving buoyancy and enabling easy transport.
- Rotating Hull Boat Design for Capsizing Prevention
Outer shell rotates on ball bearings to keep inner cabin level, preventing capsizing in rough seas.
- Hull Buoyancy Device with Adjustable Pressure Medium for Easy Removal
Adjustable connecting means and pressure sinks reduce floater attachment force against the hull side, resolving removal difficulties caused by high buoyancy.
- Pivotable Trimaran Outriggers for Shallow Water Maneuverability
Pivoting outriggers with retractable hydrofoils resolve draft limitations in shallow water while maintaining racing characteristics.
- Inflatable Bladder Seals Yacht Hull Openings Below Waterline
A yacht preserver system deploys an inflatable bladder to seal hull openings, preventing catastrophic sinking when bilge pumps fail.
