Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile swimming pool filtration and maintenance units face challenges with electrical supply safety and structural integration, requiring expensive and fragile safety devices, and pose installation and safety issues due to the need for permanent connections and flexible conduits.
Innovation Solution
A modular filtration and maintenance unit design with two distinct parts, one immersed in the pool and the other outside, connected by a low-profile pipe conduit system that allows for safe electrical supply routing and reduced structural impact, featuring a flow multiplier device and a buoyant contaminant basket for efficient filtration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the drive motor is placed inside the filtration unit in the pool, then the unit can be compact and integrated, but electrical safety becomes a serious concern with expensive and fragile safety devices required
Solution Approach 1:
The system is divided into two separate parts: a filtration unit with flow multiplier device placed inside the pool, and a pump with motor placed outside the pool. These parts are connected via flexible hoses, allowing the motor to be isolated from water while maintaining functional integration. This segmentation resolves the contradiction by achieving both compact design and electrical safety.
Solution Approach 2:
Flexible hoses act as intermediaries connecting the filtration unit and pump across the pool boundary. These hoses allow water and air flow while enabling the motor to remain outside the water environment, thus maintaining electrical safety without compromising system integration.
2Reliability
If permanent connections are made in the pool structure for water circulation pipes, then the connection is stable and reliable, but the installation becomes expensive and requires structural modifications
Solution Approach 1:
The system uses flexible, movable connections (hoses) instead of fixed permanent pipes. These dynamic connections can be easily installed and removed without structural modifications, reducing installation cost and complexity while maintaining sufficient connection stability for the application.
3Ease of manufacture
If flexible conduits are used for water circulation connections, then installation is easier and no structural modification is needed, but safety and aging problems arise
Solution Approach 1:
The patent uses air circulation instead of water circulation through flexible conduits. An air blower creates air currents that achieve the same cooling and drying effects without requiring water-tight flexible hoses, thereby eliminating safety and aging problems while maintaining installation ease.
4Productivity
If the flow multiplier device is placed inside the pool, then it can directly treat pool water, but the connecting device height increases creating a significant obstacle
Solution Approach 1:
The system separates the water treatment function (flow multiplier inside pool) from the power source (pump outside pool), connecting them via horizontal hose routing along the pool edge rather than vertical stacking. This dimensional rearrangement reduces the height obstacle while maintaining direct water treatment capability.
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
Enhances safety and integration by reducing the apparent size and weight of the filtration unit, allowing for easier installation, removal, and transport while maintaining effective filtration performance with a low-profile connecting device and efficient contaminant retention.
Implementation Method 1
a flow multiplier device which comprises an ejector which projects a stream of pressurized water into a convergent followed by a conduit
Implementation Method 2
a second part being intended to be arranged, in plan view, at outside the perimeter of the swimming pool and to transmit water under pressure to the first part

AI summary
The invention concerns filtering of swimming pool water. It concerns a filtering and maintenance unit for swimming pool comprising a housing which delimits, in a first part (16), a first volume directly connected to the swimming pool water and a second volume connected to the first only via a filtering cartridge (40) of a filtering assembly borne by a support between at least one water inlet and at least one water outlet, and the first part of the housing (16) includes a conduit (44) which connects the lower part of the cartridge (40) to the outside of the lower part of the first housing part (16), such that the inside of the cartridge receives the water from the surface and the swimming pool water at a level much lower than the surface.
