Boat Wake Adjustment System with Rotating Deflectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing boats lack the capability to adjust the size and shape of their wake to accommodate different watersports, such as waterskiing, wakeboarding, and wake surfing, which require specific wake conditions for optimal performance.
Innovation Solution
A wake adjustment system comprising pair of wake adjustment devices mounted to the stern of the boat, each with a water deflector pivotally attached to a non-parallel pivot axis, allowing independent rotation to modify the wake, and a control system to adjust the deflector's angle for varying wake sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wake-shaping devices are added to boats, then the ability to adjust wake size and shape for different watersports is improved, but the device complexity increases
Solution Approach 1:
The wake adjustment system is divided into multiple independent wake adjustment devices, each with its own water deflector that can be controlled separately. This segmentation allows different portions of the wake to be adjusted independently to create various wake shapes for different watersports activities.
Solution Approach 2:
The water deflectors are designed to be rotatable about pivot axes, allowing dynamic adjustment of the wake characteristics. The deflectors can change their orientation and position to modify water flow patterns, enabling the system to adapt wake size and shape in real-time for different watersports conditions.
2Adaptability or versatility
If non-parallel pivot axes are used in wake adjustment devices, then the adaptability to different boat hull designs is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The pivot axes of the water deflectors are deliberately designed to be non-parallel to each other, creating an asymmetric configuration that allows the wake adjustment devices to accommodate different boat hull designs and stern geometries. This asymmetric arrangement provides flexibility in adapting to various hull shapes and sizes.
3Measurement precision
If multiple independent wake adjustment devices are installed, then the wake control precision for different watersports is improved, but the device complexity and cost increase
Solution Approach 1:
Each wake adjustment device with its rotatable water deflector is designed to perform multiple functions: adjusting wake size, shaping wake contours, and adapting to different watersports requirements. This multi-functionality reduces the need for entirely separate systems for different watersports activities.
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
Enables the boat operator to create a surf wake suitable for wake surfing and adjust the wake for other watersports by deflecting water effectively, enhancing the surfing experience and accommodating different boat hull designs.
Implementation Method 1
Each water deflector is rotatable about the pivot axis so as to modify the boat's wake

AI summary
A wake adjustment system for a boat may include a wake adjustment device mountable at the stern of the boat to deflect water moving past a stern trailing edge of the boat's running surface. The wake adjustment device includes water deflectors that are rotatable about a first pivot axis for varying a degree of wake adjustment. The wake adjustment device is mounted to the boat proximal to the centerline.
