Solution Overview

Problem

Existing strainer/filter assemblies in marine cooling systems require frequent removal and cleaning, leading to excessive wear and tear, mechanical breakdowns, and increased costs due to the need for complete replacement.

Innovation Solution

A filtering apparatus with a removable mesh screen that can be easily secured and released around a longitudinal beam member, allowing for quick cleaning and maintenance without the need for complete replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the strainer/filter assembly is frequently removed and cleaned, then the filtration function is maintained, but the mechanical wear increases and the assembly eventually breaks down

Engineering Contradiction:
Improvefiltration functionVSAvoidservice life of filter assembly
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The filter assembly is divided into separate components: a reusable housing/beam member structure and a replaceable mesh screen. This allows the mesh screen to be individually replaced when worn or clogged, while the main structural components remain in service, thus maintaining filtration reliability without compromising the overall assembly's service life.

Inventive Principle:
Principle #1Segmentation

2Loss of time

If the mesh screen is made removable for easy cleaning, then maintenance time is reduced, but the structural complexity increases

Engineering Contradiction:
Improvemaintenance timeVSAvoidfilter assembly structure
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The mesh screen is designed with dynamic characteristics - it can be easily inserted and removed from the beam member structure. This dynamic design allows quick maintenance replacement without complex tools or procedures, reducing maintenance time while the modular nature keeps the overall structural complexity manageable.

Inventive Principle:
Principle #15Dynamics

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 apparatus enables efficient filtration of raw seawater, reduces downtime and maintenance costs, and extends the service life of the filter assembly by allowing individual components to be replaced or repaired.

AI summary

An apparatus for filtering raw sea water and methods for using the same are provided. The apparatus includes a longitudinal beam member having a first end and a second end. A first header is located about the first end of the beam member and a second header is located about the second end of the beam member. A removable mesh screen can be disposed around the beam member and between the first and second headers, defining an inner cavity between an inner surface of the removable mesh screen and outer surface of the beam member. A handle can be disposed on the first header. The removable mesh screen includes at least one latching member that is configured to secure the mesh screen around the beam member when latched and to release the removable mesh screen from around the beam member when unlatched.
