Marine Engine Strainer Assembly with Integrated Flush Port
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flush kits for marine internal combustion engines are bulky and require numerous fittings, making them inconvenient for use in strainers, and there is a need for a system that can efficiently drain water from the cooling system for winterization.
Innovation Solution
A strainer assembly with a housing, a removable strainer, and a rotatable collar that allows for easy flushing with a garden hose, enabling quick emptying and cleaning of debris from the cooling system, and facilitating water drainage for winterization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flush kit is used for marine engines, then the cooling system can be flushed to remove salt and debris, but the flush kit requires numerous fittings, clamps and bulky components making it inconvenient
Solution Approach 1:
The patent combines the strainer and flush kit into a single integrated assembly. The housing serves dual purposes as both the strainer housing and the flush kit body, eliminating the need for separate flush kit components. The flush port is integrated into the strainer housing, and the plug system is built into the same structure, thereby reducing the total number of fittings and components while maintaining complete flushing functionality.
Solution Approach 2:
The strainer housing is designed to perform multiple functions: it acts as both a strainer housing and a flush kit body. The same housing that contains the strainer also serves as the container for the flush operation, and the outlet port serves both as the strainer outlet and the flush port. This multi-functionality eliminates the need for separate dedicated flush kit components.
2Adaptability or versatility
If a separate flush kit is used for winterization, then water can be drained from the cooling system, but it requires additional bulky components and fittings
Solution Approach 1:
The patent merges the winterization drainage capability into the existing strainer assembly. The flush port and plug mechanism, already integrated into the strainer housing, enable both flushing and winterization drainage functions through the same components, eliminating the need for separate winterization equipment.
Solution Approach 2:
The integrated assembly provides universal functionality for both operational flushing and winterization drainage. The same housing, flush port, and plug system used for flushing the cooling system during operation also serve for draining water during winterization, making the system adaptable to multiple maintenance needs without additional components.
3Reliability
If the strainer is permanently installed in the housing, then the cooling system is protected from debris, but the strainer cannot be easily removed for cleaning
Solution Approach 1:
The strainer is designed as a separate, removable component that can be easily extracted from the housing through the outlet end. The strainer is segmented from the housing structure, allowing it to be removed for cleaning while the housing remains in place. This segmentation enables maintenance of the strainer without removing the entire assembly from the cooling system.
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
The strainer assembly allows for efficient flushing and drainage of marine engine cooling systems, reducing maintenance complexity and ensuring engine safety by removing debris and salt residue effectively.
Implementation Method 1
a strainer removably located inside the internal cavity of the housing
Implementation Method 2
a rotatable collar having internal threads adapted to engage the exterior threads of the second portion of the plug to close the flush port

AI summary
A strainer assembly for a marine engine has a housing with an internal cavity. The housing has a threaded inlet end, an outlet and a flush port. A removable cover assembly covers the threaded inlet end and may be removed to allow a strainer to be removed from inside the housing and cleaned. The flush port may be closed with a plug and opened to allow a threaded end of a garden hose to be attached to the flush port for cleaning the engine.
