Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-rolling gyroscopic stabilizers for boats face inefficiency and reduced reactivity due to the lack of active solutions for restoring the optimum configuration of the stationary, oscillating, and flywheel frames, leading to limited stabilization and impaired counter-turning maneuvers.
Innovation Solution
The integration of elastic damping means that follow external disturbances and reposition the stabilizer to its optimal configuration, combining with hydraulic or pneumatic damping elements to control oscillation velocity and amplitude, ensuring the flywheel's axis returns to its undisturbed position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If damping elements are used to limit oscillation amplitude and velocity, then oscillation control is improved, but the device loses ability to actively restore optimum configuration
Solution Approach 1:
The patent combines damping elements with elastic restoring elements into a unified system. The damping elements control oscillation velocity and amplitude, while the elastic elements simultaneously provide active restoration to the optimum configuration. This merging resolves the contradiction by making the system both stabilizing and self-restoring.
Solution Approach 2:
The elastic elements act as feedback mechanisms that detect deviation from the optimum configuration and generate restoring forces to return the system to its optimal state. This feedback capability enables active restoration while the damping elements continue to control oscillations.
2Reliability
If the flywheel frame oscillates with large amplitude, then the gyroscopic effect diminishes, but increasing oscillation amplitude seems to provide more stabilization
Solution Approach 1:
The patent controls the oscillation parameters (amplitude and velocity) of the flywheel frame through the damping elements. By maintaining oscillation amplitude within optimal ranges, the system preserves the gyroscopic stabilization effect while preventing excessive yawing movements that would occur at large amplitudes.
3Stability of the object's composition
If damping elements prevent return to undisturbed position, then oscillation is controlled, but reactivity to counter-turning maneuvers is reduced
Solution Approach 1:
The patent creates a dynamic system where the elastic restoring elements enable rapid response to external disturbances and maneuvering commands. The combination of damping and elastic restoration allows the system to quickly adapt to changing conditions while maintaining controlled oscillations, thereby improving reactivity without sacrificing stability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances the stabilization efficiency and reactivity of the anti-rolling gyroscopic stabilizer by actively restoring the optimal frame configuration, maintaining maximum stabilization and enabling smooth counter-turning maneuvers.
Implementation Method 1
The gyroscopic effect occurs when a mass, caused to rotate about a generic first axis, owing to the action of an external force is subject to a rotation about a second axis perpendicular to the first axis, thereby generating a precession movement of the first axis in a direction perpendicular to the plane defined by the first and second axes.
Implementation Method 2
thereby generating a precession movement of the first axis in a direction perpendicular to the plane defined by the first and second axes
Implementation Method 3
Such elastic means follow a disturbance induced externally on the stationary frame/oscillating frame/flywheel assembly, and reposition the stabilizer in its optimum operative configuration.
Implementation Method 4
The prior art envisages, as a solution to the aforementioned problem, the use of devices for damping the precession velocity, which act on at least one of the pivots connecting together the fixed frame, integral with the boat, and the frame supporting the flywheel.

AI summary
An anti-rolling gyroscopic stabilizer for boats comprises a stationary frame (12, 64) fixed to the hull, an oscillating frame (16, 62) and a flywheel (18, 60). The angular velocity of oscillation of the oscillating frame (16, 62) is limited by hydraulic dampers (34, 78). Elastic return elements (32, 70) are coupled to the dampers and urge the oscillating frame (16, 62) so as to orient the axis of rotation of the flywheel (V, B) towards a given angular position in which the gyroscopic device acts with maximum efficiency.
