Elongated Pool Filter Basket for Reduced Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pool filtration systems require frequent maintenance and water usage due to small filter sizes and inefficiencies in removing fine particulates, and lack accessibility for cleaning and replacement, especially in areas with deciduous trees nearby.
Innovation Solution
A modular filtering system with a vertically elongated inlet housing and filter assembly featuring a porous filter basket and filter bag that can be easily accessed through standard pool deck openings, allowing for efficient removal of particles as small as 300 microns with minimal maintenance and water usage, and optional integration with ozone purification systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fine mesh filter is used to remove small particles (300 microns), then filtering effectiveness is improved, but the filter clogs frequently requiring maintenance
Solution Approach 1:
The filter system is divided into multiple independent filter baskets that can be individually removed and cleaned through the access portal. Each basket contains a portion of the total filtering surface area, allowing one basket to be maintained while others remain in service. This segmentation enables frequent fine-mesh filtering without requiring complete system shutdown for maintenance.
Solution Approach 2:
Multiple filter baskets are nested within the filter housing, with each basket containing filter media. The baskets are designed to fit within the housing space constrained by the access portal dimensions. This nesting arrangement maximizes the total filtering surface area within the available volume while maintaining individual accessibility of each basket for cleaning.
2Ease of operation
If a large surface area filter is used to prevent clogging, then maintenance frequency is reduced, but the filter cannot fit through standard access portals
Solution Approach 1:
The total filter surface area is divided into multiple separate filter baskets, each with a smaller individual area that can pass through the access portal. When combined, these baskets provide the equivalent of a large surface area filter. This segmentation allows the system to achieve both large total filtering area and individual component accessibility.
Solution Approach 2:
Instead of increasing the diameter of a single filter (two-dimensional expansion), the system increases the number of filter baskets (adding a third dimension of quantity). This vertical stacking of multiple baskets within the housing provides large total surface area while keeping each individual basket compact enough to fit through standard access portals.
3Ease of manufacture
If the filter access portal is made small to maintain pool aesthetics and safety, then appearance and safety are improved, but filter installation and removal becomes difficult
Solution Approach 1:
The filter system is segmented into multiple smaller baskets that can be individually manipulated through the constrained access portal. Each basket is sized to fit through the small opening, making installation and removal feasible despite the limited access. The segmented design transforms an inaccessibly large filter into a series of manageable components.
Solution Approach 2:
The filter baskets are designed with flexible or movable components that allow them to be compressed or adjusted during insertion through the access portal, then expand to their full filtering capacity once installed. This dynamic adjustment enables passage through small openings while maintaining large surface area for filtering.
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 system effectively reduces maintenance needs and water usage by enabling longer filter runs and easy access for cleaning, while maintaining pool aesthetics and safety, effectively filtering small particles and integrating ozone treatment for improved water quality.
Implementation Method 1
the filter assembly includes a porous filter basket removably secured within the filter chamber and a filter bag lining the porous filter basket... the water is drawn through the filter bag and through the porous filter basket

AI summary
The present pool filtering system provides an elongated fine mesh filter with a large surface area; which can be removed and inserted through a standard filter access port found on pool decks. Because the filter assembly length is at least twice the diameter measurement, a large surface area is possible while remaining compact. The filter assembly includes a cylindrical porous filter basket that is completely lined with a filter bag. The filter bag can filter particulate matter as fine as three hundred microns or less. The present filtering system can provide preliminary filtering before water is delivered for further conditioning by secondary filters, heater, or the like. The present filter permits fine filtering without constant clogging or maintenance. When maintenance is required, there is easy access for cleaning and replacement. The elongated weir housing and weir door allows for a greater operating range of pool water level.
