Cargo Handling Apparatus TRIZ Cases

A clamp-mounted boarding aid with a telescopic slide arm and rubber handgrip stabilizes passengers during vessel docking.

A transportable subsea station docks with an autonomous underwater vehicle to reduce deployment time and operational costs.

A fluidtight membrane assembly uses a fourth plate with a curved convex corner to enable continuous welding along longitudinal and transverse strips.

A fluid transfer duct employs a mobile rigidification element to align flexible segments, resolving handling difficulties during ship-to-ship LNG operations.

An automatically releasable coupling separates manifold parts when force exceeds a limit, enabling controlled fluid exchange.

Hydraulic hull extensions lift the stern platform to keep swimmers clear of propellers while a porous grille reduces wave forces.

An interlock mechanism locks an aircraft door in a lifted position to provide firmness and stability for the airstair.

A transport system featuring a swappable battery pack design with a charging station and transfer device that allows for efficient battery swapping between the vessel and a charging station.

A boat launch platform uses a vertically movable floating floor to transition between land and water configurations.

Buoyant boats carry umbilical loads to reduce winch drum weight, while angled spring chains grip cables without deformation.

Nesting a pivoting door within the terrace structure resolves space constraints, enabling compact vessel deck expansion and safe embarkation.

Polygonal stiffening frames surround longitudinal beams to resist deformation under bending-torsion loads.

Segmented sacrificial layer panel absorbs external impact energy to protect composite supporting components from damage.

A catamaran vessel transfers cargo to barges at sea using a quad-maran configuration.

A single-axis gimbal mast pivots to compensate for vessel roll using one actuator and counterweights.

A polygonal inflatable float bridges two vessels to prevent collisions and enable safe multi-person transfer.

Amidships pontoons provide longitudinal buoyancy to support an extendable lower deck, maintaining stability and increasing usable space.

A free-standing casing uses a T-shaped groove to receive wing-shaped welding supports for thermally insulating sealed membranes.

Movable bulkheads with ballasts align and receive target objects from water, resolving dynamic displacement challenges.

A modular hull-mount frame with a pivoting boom and lifter automates unmanned surface vehicle deployment.

A docking station moves an underwater robot via a conveyor unit to an above-water maintenance area for charging.

A telescopic beam assembly with a movable carriage enables safe transfer of persons and cargo between vessels and offshore structures.

A reversible speed reducer actuator drives fluid transfer lines via electric motors and braking means.

Coupling station synchronizes winch cable and hoist element travel speeds to enable automatic attachment, reducing manual handling errors.

A landing gangway features a front rod that rotates from a rest position to an upright operating position.
