Flexible Hull Cleaning Line for Marine Growth Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional boat hull cleaning methods, such as mechanical or chemical means, are inefficient and pose health risks, while existing submerged cleaning devices like belt and float technologies face difficulties in engagement, control, and effectiveness in removing marine growths.
Innovation Solution
A boat hull cleaning system featuring a flexible line with cleaning elements that extend outwardly from a central portion, allowing reciprocal engagement with the hull, providing adjustable spacing and flexibility to effectively clean both raised and recessed areas without the need for removal from the water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mechanical or chemical cleaning methods are used out of water, then cleaning effectiveness is improved, but the complexity of operation and health risks increase due to requiring boat removal from water or use of toxins
Solution Approach 1:
The patent replaces conventional mechanical scrubbing and chemical cleaning methods with a water jet system that uses high-velocity water streams to remove marine growth. The flexible hose with spray nozzles delivers kinetic energy through water flow, eliminating the need for mechanical contact with brushes or abrasive pads and avoiding chemical toxins entirely.
Solution Approach 2:
The patent employs a flexible hose that can be maneuvered along the boat hull to deliver water jets to all areas. This flexible delivery system adapts to the contours of the hull, allowing effective cleaning of both raised and recessed areas without requiring the boat to be removed from water or complex positioning equipment.
2Ease of operation
If belt and float technology is used for submerged cleaning, then the need for boat removal is avoided, but the difficulty of engagement and control increases
Solution Approach 1:
The patent extracts the cleaning function from complex mechanical systems (belts, floats, brushes) and concentrates it in a simple flexible hose with spray nozzles. This removes the engagement and control difficulties associated with mechanical contact systems while maintaining submerged cleaning capability. The water jet system requires no mechanical engagement with the hull surface.
Solution Approach 2:
The patent uses hydraulic principles by delivering high-velocity water through a flexible hose to achieve cleaning. The water jet system utilizes fluid dynamics and kinetic energy of moving water to remove marine growth, replacing complex mechanical systems with a simpler fluid-based approach that is easier to control and engage.
3Area of stationary object
If flat belt is drawn against boat hull, then cleaning coverage is improved, but friction between belt and hull increases making it difficult to move back and forth
Solution Approach 1:
The patent replaces the flat belt mechanical contact system with a flexible hose delivering water jets. This hydraulic approach maintains cleaning coverage by allowing the hose to conform to hull contours, while eliminating the high friction forces that resist movement. The water jets clean without mechanical dragging, significantly reducing the force required to move the cleaning device along the hull.
4Manufacturing precision
If cleaning pads are supported in fixed positional relation to hull, then cleaning consistency is improved, but adaptability to different hull configurations decreases
Solution Approach 1:
The patent uses a flexible hose that can adapt to various hull configurations while maintaining consistent cleaning performance. The flexibility allows the hose to conform to raised areas, recessed areas, and different hull shapes, providing universal adaptability. The spray nozzles deliver consistent water jet patterns regardless of hull geometry, achieving both consistency and versatility.
