Steering By Jets TRIZ Cases

A rotating interior nozzle splits impeller flow across fixed jet tubes to hold vessel position quietly without anchors or exposed propellers.

A vertical impeller and pump housing give shallow-draft boats permanent lateral thrust without fragile deployed trolling motors.

Pumps direct water through distributed pontoon outlets, giving the boat tighter turns and more precise position and orientation control.

Integrating thruster tunnels into the molded hull cavity eliminates drilling and preserves structural integrity.

A lateral thrust device redirects reverse jet flow through a curved channel to generate side force.

Dual nozzle deflectors orient opposing water jets relative to the center of gravity, eliminating rudder dependency and stabilizing straight-line travel.

A water jet propulsion boat adjusts its jet stream direction and force to maintain a stable bow-up attitude.

A jet propulsion boat uses independent electric and engine thrusters for multi-directional movement.

A rotatable second discharge portion changes jet water direction to steer a propulsion boat, eliminating complex fixed port arrays and reducing component count.

Segmented lateral gears allow independent tail and fin movement, resolving maneuverability complexity trade-offs for tight space exploration.

Hydrodynamic thrust from multiple rotors enables a swimming pool robot to navigate the entire water volume, resolving limited surface cleaning coverage.

Movable cover plates adjust cooling air injection to redirect exhaust gas, eliminating complex mechanical piping for thrust vectoring.
