Hydrodynamic/Hydrostatic Features TRIZ Cases

A truncated head joint lets the hydrofoil rotate to adjust angle of attack while reducing strut bending, wear, and pop-out risk.

A mono-hull with aft catamaran sponsons improves stability in choppy seas, cuts spray at speed, and preserves interior space.

A retractable strut lifts the hydrofoil and propeller above water to avoid collision damage, cut drag from foldable linkages, and support shallow-water use.

Pivoting foils retract into hull recesses to cut draft and damage risk while preserving multi-hull vessel aesthetics and maneuverability.

Overlapping tapered fuselage sections lock inside a collar to avoid threaded corrosion and enable quick, tool-free hydrofoil assembly.

End stabilizers and adjustable strap loops let tethered watercraft move vertically with waves while resisting lateral drift and abrupt impacts.

Positioning the hydrofoil rotation shaft forward of the center of lift cuts actuator moment while maintaining angle of attack control.

By moving the hydrofoil pivot ahead of the center of area, this case reduces actuator torque while maintaining stable angle-of-attack control.

Cam-linked foil pivoting keeps the hydrofoil aligned with water flow during impact retraction, reducing abrupt deceleration and damage.

A retractable hydrofoil strut shelters its adjustment mechanism behind a blunt trailing edge to avoid drag while protecting against seabed or object strikes.

A plumb-bow pontoon with triple V-shaped bottom surfaces and bow vents redirects water flow to improve lift, drag, speed, and handling.

A cross-hatched chassis ties spaced pontoons into a stiffer frame, limiting twist in rough water while adding battery space with low weight.

A hollow T-connector creates an internal chamber in the mast and foil to house force, signal, and fluid elements without added drag or water exposure.

Wedge-shaped hull vortex generators are positioned near boundary-layer detachment to delay separation, cut form drag, and improve ship fuel efficiency.

An upstream weed deflector redirects weeds away from the hydrofoil to cut drag, protect lift, and keep boat propulsion smooth.

Angled mast insertion and double locking simplify foil assembly on boards while improving attachment stability and resistance to contamination.

Strategically positioned chines and foils help pontoon boats handle high speeds with improved stability and hulled-boat-like behavior.

Hinged tubular sections, inflatable pontoons, and modular coupling make a fishing raft compact to transport yet expandable for multiple users.

Model-specific adapter parts connect universal support blocks to boat structures, simplifying hydrofoil installation across boat types.

Individually controlled flaps combine IMU, GPS, and rider input to stabilize pitch and manage propulsion during waves and stops.

A propulsion controller detects foil lift loss and increases thrust, helping hydrofoil vessels transition from foiling to water contact.

Hybrid deep-vee hull transitions from V-shaped to M-shaped cross sections using segmented deadrise angles.

Movement apparatus rotates appendages around orthogonal axes to maintain stable navigation, resolving mechanical reliability issues during sudden turns.

Adjustable hydrofoils below the waterline control running trim and support vessel weight across varying speeds.

A segmented air dispersal system reduces viscous resistance across the wetted hull without requiring dry-docking for installation.

Pentagonal columns with inboard triangular extensions widen pontoon spacing to improve hydrodynamic performance and reduce topsides weight.

Compressed air creates an air film along the hull exterior, reducing friction and energy consumption for high-speed planing watercraft.

Vertical positioning of a mobile working deck resolves the contradiction between BOP storage capacity and horizontal deck area constraints.

Representing heaving acceleration with a Prony sequence removes baseline drift errors and improves measurement precision.

A composite hydrofoil framework combines a rigid foam core with a flexible outer layer to reduce weight and eliminate sharp edges that increase drag.

A column platform construction method integrates prefabricated modules into a unified bottom deck placed within the barrel skylight opening.

Segmenting the hull into three parts increases trap storage area without increasing power requirements, achieving 20% lower fuel consumption.
