Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swimming pool cleaners face issues with filter clogging, reduced suction performance, and operational inefficiencies due to traditional filter elements and obstacles during cleaning, leading to incomplete pool cleaning and maintenance challenges.
Innovation Solution
The implementation of a swimming pool cleaner with a hydrocyclonic particle separator assembly and a drive system featuring six driven brushed rollers, which includes a canister subassembly with cyclone containers and a filtering medium to effectively separate debris and improve navigation over pool surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional filter elements (bags, mesh, baskets) are used in the pool cleaner, then debris can be trapped and contained, but the filter elements quickly become clogged or occluded, reducing cleaner performance and requiring frequent cleaning or replacement
Solution Approach 1:
The patent replaces traditional mechanical filter elements (bags, mesh, baskets) with a hydrocyclonic separation system that uses centrifugal force generated by rotating fluid flow to separate debris from water. This substitution eliminates the clogging issues inherent in mechanical filters while maintaining effective debris capture.
Solution Approach 2:
The invention employs hydraulic principles through the use of water flow to generate cyclonic motion within the separation chamber. The fluid dynamics create centrifugal forces that separate debris based on density and size, allowing continuous operation without the mechanical filtration limitations.
2Reliability
If traditional filter elements are used, then debris can be contained, but the surface area of the filter becomes clogged prior to the debris retention volume being filled to capacity, reducing suction performance
Solution Approach 1:
The hydrocyclonic separation system replaces surface-based mechanical filtration with volume-based centrifugal separation. Debris is separated throughout the fluid stream rather than being trapped on a surface, preventing clogging and maintaining suction performance throughout the debris retention cycle.
Solution Approach 2:
The invention changes the separation mechanism from surface-area-limited mechanical filtration to volume-based hydrocyclonic separation. This parameter change allows the system to handle larger quantities of debris without performance degradation, as separation occurs through the bulk fluid flow rather than on a constrained surface.
3Ease of repair
If users directly handle filter elements and debris for cleaning or replacement, then filter maintenance can be performed, but debris and water may get on the user, creating inconvenience
Solution Approach 1:
The hydrocyclonic separation system is designed to be self-cleaning through the continuous fluid flow that naturally flushes debris from the separation chamber. The system maintains itself without requiring user intervention for filter cleaning, eliminating the inconvenience of handling debris and water.
Solution Approach 2:
The invention extracts the maintenance burden from the user by designing a system where debris is continuously removed through the hydrocyclonic action and discharged separately from the cleaner body, allowing maintenance without direct user contact with contaminated components.
4Productivity
If the pool cleaner encounters obstacles (lights, drains) during cleaning, then the cleaner may get stuck, but this results in the pool being only partially cleaned
Solution Approach 1:
The cleaner incorporates dynamic adjustment capabilities that allow it to adapt its movement and cleaning pattern in response to obstacles. The system can modify its trajectory, speed, and cleaning intensity to navigate around obstacles while maintaining overall cleaning productivity and completion.
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 debris separation and filtration efficiency, reduces filter clogging, and allows for easier maintenance by effectively handling debris and navigating around pool obstacles, ensuring thorough cleaning and extended filter life.
Implementation Method 1
Fluid being pulled through the canister subassembly and intake enters the canister body at the tangential inlet forming a cyclonic flow (e.g., a first cyclonic flow) about a first axis within the canister body
Implementation Method 2
The example first cyclonic flow includes debris-laden fluid having small and large debris, with the large debris being separated from the flow through cyclonic action
Implementation Method 3
a pump system continuously circulates water through a filter assembly of the pool cleaner capturing debris and any suspended particulate therein
