Gyroscope Wakeboat Trim Tab Asymmetric Surf Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wakeboat technologies face limitations in generating desirable asymmetric wakes due to restricted dynamic range of trim tabs, complexity, and potential safety hazards from vertically oriented trim tab elements and additional rudders.
Innovation Solution
A system comprising pivotally supported trim tabs and a gyroscope with a rotor and frame, allowing for adjustable asymmetric wake formation by controlling lift and yaw, which works with minimal modifications to existing hull designs and avoids hazards in populated areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If trim tabs are used to generate asymmetric wakes, then wake asymmetry is achieved, but the dynamic range is restricted
Solution Approach 1:
The trim tab is divided into multiple independent segments (first trim tab segment, second trim tab segment, third trim tab segment) that can be controlled separately. This segmentation allows each segment to contribute differently to wake asymmetry, expanding the dynamic range and versatility of wake formation while maintaining manageable system complexity through modular control.
2Adaptability or versatility
If vertically oriented trim tab elements are added to delay wake convergence, then wake formation is improved, but safety hazards increase in populated areas
Solution Approach 1:
Instead of using vertically oriented elements that extend upward into the air space above the water, the invention uses horizontally oriented trim tab segments at the transom that control wake convergence through horizontal water flow manipulation. This dimensional change eliminates safety hazards for swimmers and participants in the water while maintaining the ability to delay wake convergence and shape the asymmetric wake.
3Adaptability or versatility
If additional rudders are added to create asymmetric wakes, then wake asymmetry is achieved, but device complexity increases
Solution Approach 1:
The trim tab segments serve multiple functions: they control hull trim, generate asymmetric wake, and delay wake convergence, all without requiring additional rudders or steering components. The same trim tab mechanism that adjusts hull attitude also creates the asymmetric wake pattern, eliminating the need for separate asymmetric wake generation devices and reducing overall system complexity.

Implementation Method 1
a gyroscope including a rotor and a frame, the rotor rotatably supported by the frame, the frame rotatably supported by the hull, the rotor configured to selectively spin within the frame on a first gyroscope axis
Implementation Method 2
the frame configured to selectively spin within the hull on a second gyroscope axis which is non-parallel with the first axis
Implementation Method 3
a trim tab including a main tab portion pivotably supported from the stern of the boat for rotation about a first axis

AI summary
A wakeboat has a hull, the hull forming a wake when moving forward in the water, with a left quiet region and a right quiet region in the wake. The hull may exhibit rotation around one or more of its roll, pitch, and yaw axes which affects the quiet regions in the wake. A gyroscope supported in the hull may be used to rotate the hull around one or more axes. Such rotation may be used to create a surf left and/or surf right configuration, and measured via one or more sensors. Other systems and methods are also provided.
