Flexible Hull Scrubber Head for Marine Vessel Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for cleaning boat hulls are inefficient, expensive, and require significant time and resources, often necessitating dry docking, which is costly and logistically challenging, especially for vessels traveling long distances.
Innovation Solution
A hull scrubber device comprising a flexible, spiral-shaped scrubber head that transforms into a cylinder while in operation, allowing it to spin against the hull as the boat moves, equipped with brush, felt pad, and scraper elements for effective cleaning without the need for dry docking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional hull cleaning methods (scuba diver or haul-out) are used, then thorough cleaning can be achieved, but the process becomes expensive and time-consuming
Solution Approach 1:
The hull scrubber device enables the boat to clean its own hull while moving through water. The flexible scrubber head is pushed against the hull by water pressure and boat motion, eliminating the need for external divers or haul-out equipment. The system is self-propelled by the boat's own movement, requiring no additional power source or external assistance.
Solution Approach 2:
The scrubber head is designed with flexible material that allows it to dynamically adapt its shape from a compact spiral for storage to an expanded cylindrical form during operation. This dynamic transformation enables the scrubber to conform to the hull's curvature and maintain effective contact during cleaning, while transitioning between operational and storage states.
2Reliability
If dry docking is performed for hull cleaning, then comprehensive maintenance can be conducted, but it involves significant expense and logistical challenges
Solution Approach 1:
The device transforms routine hull maintenance into a self-service operation that can be performed by the boat operator without requiring professional divers, haul-out facilities, or marina scheduling. The simplified mechanism allows any boat owner to maintain their vessel independently, eliminating complex logistical arrangements.
Solution Approach 2:
The invention extracts the essential cleaning function from the complex dry-docking process. By isolating and implementing only the hull scrubbing capability in a simplified, self-contained device, the system eliminates the need for expensive facility rentals, professional services, and extensive preparation while achieving effective cleaning.
3Extent of automation
If a robotic cleaner is deployed, then automated cleaning can be achieved, but the device becomes expensive and complicated
Solution Approach 1:
Instead of using a complex robotic system with sensors, motors, and control systems, the invention achieves automation through the boat's own motion. The water pressure and boat movement automatically drive the scrubber head against the hull, eliminating the need for electronic controls, power sources, or mechanical actuation systems.
Solution Approach 2:
The scrubber head is designed as a simple, inexpensive component made from flexible material that can be easily replaced if needed. This simple construction avoids expensive materials and complex manufacturing, making the device economically viable while maintaining effective cleaning capability.
4Manufacturing precision
If scuba diver cleaning is used, then effective hull scraping can be performed, but availability of diver and equipment becomes a constraint
Solution Approach 1:
The boat carries its own cleaning capability in the form of the hull scrubber device, eliminating dependence on external divers or equipment availability. The system is always available whenever the boat is in motion, allowing cleaning to be performed on-demand at any location without scheduling constraints or external resource dependencies.

Function Achieved in This Case
Enables efficient and cost-effective hull cleaning while the boat is in motion, reducing the need for expensive maintenance operations and minimizing marine growth, allowing for maintenance anywhere and anytime.
Implementation Method 1
a hull scrubber head having a first end attached to the tether rope and a distal end spaced away from the hull, the hull scrubber head being made of a flexible material and in a spiral shape configuration when in an inoperative mode and essentially in a cylinder shape configuration when in an operative mode
Implementation Method 2
uses the movement of the boat to assist in the hull cleaning process, thereby increasing the efficiency of the cleaning process
Implementation Method 3
the hull scrubber head... spins or rotates against the hull as the boat moves through the water

AI summary
A hull scrubber device for a boat is deployed into an operative mode when the boat travels through the water. The device includes a mounting pole and a flexible hull scrubber head attached to the mounting pole and tethered via a tether rope and a swivel mounting in the hull scrubber head. The device is structured to rotate or spin and hit against the boat hull as the boat moves through the water. The scrubber head is a flat-like spiral disk when in a storage, inoperative mode. This disk assumes the shape of a cylinder when hull scrubber device is fully deployed in the water. Brush elements, felt pad elements, and scraper elements are mounted on an outer edge surface of the hull scrubber head for cleaning the hull. Related methods of cleaning a boat hull are also disclosed.
