Pool Filtration System With Weighted Return Hose
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool filtration systems fail to effectively circulate all areas of the pool water, leading to poor filtration of foreign matter such as leaves and debris.
Innovation Solution
A pool filtration system that includes a skimmer with a barrier filter and a return hose with a weight attached to its distal end, allowing the hose to move in a random whipping fashion and ensuring that the water is circulated below the top side of the pool water without being retained only at the bottom.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the return hose is used to circulate water in the pool, then water circulation is achieved, but the hose tends to float at the surface or sink to the bottom, preventing effective circulation of all water areas
Solution Approach 1:
A weight is attached to the distal end of the return hose to counteract the buoyancy force that causes the hose to float at the surface. This allows the hose to maintain a submerged position without requiring active control, enabling effective water circulation throughout the pool volume including areas below the surface where floating debris is not present.
2Productivity
If the return hose is weighted to stay submerged, then surface water circulation is improved, but the hose may be retained only at the bottom side preventing circulation of upper water layers
Solution Approach 1:
The return hose is designed to be flexible and dynamic rather than rigidly positioned. The hose can naturally move and adjust its position in the water column based on water flow patterns and pool conditions, allowing it to reach different water layers and effectively circulate water throughout the entire pool volume without being fixed at the bottom.
3Speed
If the pump flows water at high rate through the return hose, then circulation speed is improved, but the hose becomes difficult to control and position
Solution Approach 1:
The weight attached to the distal end of the return hose provides stability that counteracts the forces generated by high-speed water flow. This allows the system to operate at high flow rates for effective circulation while the weighted hose remains controllable and positionable, as the weight anchors the hose and prevents excessive movement or difficulty in positioning.
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 achieves efficient circulation of pool water, ensuring that all areas are filtered effectively, including the surface where floating debris is typically found.
Implementation Method 1
A pump is in fluid communication with the aperture of the skimmer and is configured for drawing water from the volume of water through the container of the skimmer
Implementation Method 2
A weight is mounted to the return hose adjacent to the distal end. The weight is configured to maintain the distal end below the top side of the volume of water
Implementation Method 3
The barrier filter is water permeable and is positioned such that water passing into the cavity through the opening and out of the cavity through the aperture must pass through the barrier filter

AI summary
A pool filtration system for filtering foreign matter such as leaves and other debris from a swimming pool includes a skimmer, a pump, and a return hose. The pump draws water from a swimming pool through the skimmer and out the return hose back to the swimming pool. The skimmer has a barrier filter for filtering out foreign matter. A weight is attached to a distal end of the return hose with respect to the pump such that the distal end of the return hose is maintained below a top side of a volume of water in the swimming pool.
