Swimming Pool Pump Filter Basket Rib for Deformation and Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filtering units for swimming pool pumps suffer from deformation and clogging issues due to high suction pressures, leading to operational inefficiencies and potential breakdowns, which existing solutions have not adequately addressed.
Innovation Solution
Incorporation of a structural rib on the inner wall of the filter basket, dividing the outlet opening into two halves, providing resistance against deformation and maintaining a constant separation between the mesh wall and the tank side wall to prevent clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high suction pressure is applied to retain solid waste in the filter, then filtering effectiveness is improved, but filter deformation occurs at the outlet area
Solution Approach 1:
The patent applies a rib structure specifically at the outlet area of the filter basket where deformation occurs, rather than uniformly reinforcing the entire basket. This localized reinforcement maintains filtering effectiveness while preventing deformation only where needed - at the outlet area subjected to high suction pressure.
Solution Approach 2:
The rib divides the outlet opening into two separate openings, creating distinct flow paths. This segmentation reduces the concentrated stress at any single point in the outlet area, preventing deformation while still allowing effective waste retention through the distributed flow paths.
2Productivity
If the mesh wall is positioned close to the tank wall to maximize filtering capacity, then filtering efficiency is improved, but clogging occurs at the outlet area
Solution Approach 1:
The rib divides the outlet opening into two separate openings, creating distinct flow paths. This segmentation prevents debris accumulation at any single point and maintains water flow channels even when the mesh wall is positioned close to the tank wall for maximum filtering capacity.
Solution Approach 2:
The rib acts as an intermediary structure between the mesh filter wall and the tank wall at the outlet area. It maintains a controlled gap that prevents direct contact between the mesh wall and tank wall, eliminating clogging points while allowing the mesh wall to be positioned close to the tank wall for maximum filtering capacity.
3Speed
If the outlet opening is kept large to maintain water flow, then flow rate is improved, but structural reinforcement becomes more difficult
Solution Approach 1:
The rib divides the large outlet opening into two smaller openings, maintaining adequate water flow rate through the distributed paths while the rib itself provides the necessary structural reinforcement. The segmentation allows the outlet to remain structurally sound without requiring excessive reinforcement that would obstruct flow.

AI summary
Filtering unit for pumping in swimming pools consisting of a hollow body comprising an inlet branch (1), an outlet branch (2), a removable filter (4) comprising a mesh wall (5), and a filtering tank (3). The tank (3) comprises an internal housing for inserting the filter (4); an inlet port (8) for the water flow from the inlet branch (1), and an outlet port (9) on the side wall (7), for the outflow of the pool water already filtered by the filter (4) to the outlet branch (2). The filtering tank (3) further comprises a structural reinforcement rib (10) on the inside face that crosses the outlet port (9) to prevent clogging and deformation.
