Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid removal systems in boats, such as bilge pumps, require electrical power, frequent manual intervention, and are prone to failure due to corrosion, mechanical issues, and environmental conditions, failing to maintain a dry bilge continuously.
Innovation Solution
A passive siphon-based apparatus utilizing hydrodynamic principles, including a bilge accumulator and siphon generator, operates without electricity, using the Venturi effect to continuously remove fluids from the bilge by harnessing natural boat motion, with optional filtration and check valves to prevent backflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a passive siphon-based apparatus is used, then reliability is improved by eliminating electrical power requirements, but device complexity increases due to additional components like bilge accumulators and siphon generators
Solution Approach 1:
The patent replaces the electrical pump system with a passive siphon-based mechanical system that uses hydrodynamic forces generated by boat motion to remove bilge water, eliminating the need for electrical power and improving reliability in marine environments
Solution Approach 2:
The siphon generator automatically activates and operates using the natural motion of the boat through water, requiring no manual intervention or external power source, thereby maintaining continuous operation and enhancing system reliability
2Productivity
If a bilge pump is used, then productivity is improved by actively removing fluid, but use of energy increases due to electrical power requirements
Solution Approach 1:
The patent substitutes the electrically-powered bilge pump with a passive siphon system that harnesses mechanical energy from boat motion, eliminating electrical power consumption while maintaining fluid removal capability
Solution Approach 2:
The system uses hydraulic principles through the siphon generator, which creates a pressure differential by utilizing the flow of water over the boat's running surface to drive fluid removal without mechanical pumps or electrical energy
3Reliability
If manual bilge pumps are used, then reliability is improved by eliminating electrical dependencies, but ease of operation deteriorates due to requiring physical effort and constant attention
Solution Approach 1:
The passive siphon system operates autonomously by utilizing the boat's natural motion through water, requiring no manual pumping action or constant operator attention, thus maintaining ease of operation while ensuring reliable continuous function
Solution Approach 2:
The system dynamically adapts to the boat's motion, automatically adjusting its operation based on the vessel's movement through water, which eliminates the need for manual intervention while maintaining operational effectiveness

Function Achieved in This Case
The apparatus maintains a dry bilge without power or manual intervention, enhancing reliability, reducing maintenance, and adapting to various boat designs, ensuring continuous fluid removal in marine environments.
Implementation Method 1
a vacuum is created via a Venturi effect, drawing fluid from the bilge through the tube and out of the boat
Data Source
AI summary
An apparatus and method for removing fluid from the bilge of a boat without electrical power or manual intervention is disclosed. The system includes a bilge accumulator positioned within the bilge to collect fluid, a siphon generator mounted on the exterior of the boat at or below the waterline, and a tube connecting the two. The siphon generator incorporates a Venturi passage that generates a vacuum as water flows across its surface during vessel motion, thereby drawing fluid from the bilge accumulator and expelling it overboard. The accumulator may include a sponge or multi-stage filter for debris removal and priming retention, and mounting components for secure installation. A check valve may be included to prevent backflow. The system operates passively and continuously while the boat is underway, maintaining a drier bilge environment without the need for electrical bilge pumps.
