Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Winterizing boats in cold climates requires manual operation to flush seawater and introduce anti-freeze into the system, typically needing two people to manage the process effectively.
Innovation Solution
A method and system utilizing air pressure to flush seawater from the system and an anti-freeze supply mechanism that can be coupled to the boat's water intake system, allowing for automated or simplified operation of flushing and anti-freeze introduction, using a funnel with a bungee cord for sealing and a pressurized gas source for efficient water removal and anti-freeze distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to flush seawater and introduce anti-freeze, then the system can be winterized, but it requires two people and increases operational complexity
Solution Approach 1:
The system uses the boat's own water pump and existing water flow to automatically flush seawater and deliver anti-freeze solution. The pump serves dual purposes: normal water circulation during operation and automated winterization when activated through the float valve mechanism.
Solution Approach 2:
The invention employs hydraulic principles using water pressure and flow control through valves and floats to automate the winterization process. The float valve uses water level differences to automatically control the timing of seawater flush and anti-freeze delivery without manual intervention.
2Extent of automation
If automated systems are used to flush seawater and supply anti-freeze, then single-person operation is enabled, but the system complexity increases
Solution Approach 1:
The system leverages the boat's existing water pump and circulation system to perform automated winterization. The pump's normal function is utilized, requiring no additional motorized components, thereby achieving automation without significant complexity increase.
Solution Approach 2:
A float valve acts as an intermediary mechanism that automatically controls the timing and sequence of seawater flush and anti-freeze delivery. The float valve responds to water level changes to trigger appropriate system actions without requiring complex electronic controls or manual operation.
3Reliability
If anti-freeze is supplied at the correct rate and location, then effective winterization is achieved, but manual coordination requires two people
Solution Approach 1:
The float valve mechanism provides automatic feedback based on water level and flow conditions to control anti-freeze delivery timing. This ensures reliable winterization by adapting to actual system conditions without requiring manual monitoring or coordination between multiple operators.
Solution Approach 2:
The system performs preliminary seawater flush before introducing anti-freeze solution, ensuring the water intake system is clear and ready. This sequence is automatically controlled through the float valve timing, ensuring reliable winterization preparation without manual coordination.
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 single-person operation to efficiently flush seawater and introduce anti-freeze into the boat's system, ensuring effective winterization without the need for manual handling, thus reducing the complexity and time required for the process.
Implementation Method 1
open the opening and couple to the opening an air pressure supply means which applies air pressure to the system; open the inlet port valve and leaving it open until air pressure has forced water out the inlet port and air has begun to escape out the inlet port
Implementation Method 2
The reservoir may be coupled to a spring, such as a bungee cord, that, when installed on the strainer, urges the conical open bottom portion into contact with the strainer

AI summary
A method for winterizing boat engines and a system with components designed for performing the method comprising an air-pressure-supply means that can be used to pressurize the system and thereby force water out the inlet port, an anti-freeze supply means that will supply anti-freeze liquid into the system when the component that is to be winterized is operated to draw water, and means for coupling these components to the water system.
