Pool Cleaner Roller Assembly with Hydrocyclonic Separator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swimming pool cleaners face issues with clogged filter elements, reduced suction performance, and difficulty in handling debris, as well as getting stuck on obstacles during cleaning, leading to incomplete pool cleaning.
Innovation Solution
The swimming pool cleaner incorporates a hydrocyclonic particle separator assembly with a canister subassembly and drive assembly featuring six driven brushed rollers, allowing for efficient debris separation and improved 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, but the filter elements quickly become clogged or occluded, reducing suction performance and requiring frequent cleaning or replacement
Solution Approach 1:
The filter assembly is divided into multiple independent filter elements (first filter element, second filter element, third filter element) arranged in parallel. This segmentation allows debris to be distributed across multiple surfaces, preventing any single element from becoming completely clogged and maintaining continuous filtration performance.
Solution Approach 2:
The filter assembly serves multiple functions: it filters debris from the water stream, provides structural support for the hydrocyclonic particle separator, and enables easy maintenance through quick-release mechanisms. The multi-functional design improves overall system efficiency and reliability.
2Reliability
If traditional filter elements are used, then debris can be contained, but the surface area becomes clogged prior to the debris retention volume being filled to capacity, requiring frequent maintenance
Solution Approach 1:
Multiple filter elements provide increased total surface area for debris retention. The segmented design allows the system to hold more debris capacity before requiring maintenance, reducing the frequency of cleanings while maintaining reliable debris containment.
Solution Approach 2:
The filter assembly incorporates a quick-release mechanism that allows users to easily remove and clean filter elements without specialized tools or complex disassembly. This self-service design significantly reduces maintenance time and effort.
3Device complexity
If the pool cleaner uses a single drive roller configuration, then the structure is simple, but the cleaner gets stuck on obstacles such as lights and drains during cleaning
Solution Approach 1:
The drive system is segmented into multiple independent drive rollers (first drive roller, second drive roller, third drive roller, fourth drive roller, fifth drive roller, sixth drive roller) distributed along the cleaner body. This segmentation allows different sections of the cleaner to navigate obstacles independently, preventing the entire system from getting stuck and improving traversal reliability.
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 solution enhances debris separation and filtration efficiency, reduces the likelihood of clogged filters, and enables the cleaner to effectively traverse pool surfaces, including obstacles, ensuring thorough cleaning without manual intervention.
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 and between the canister body and the filtering medium
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 and contact with the canister body and the filtering medium
Implementation Method 3
A motor housing includes a pump motor operatively connected to an impeller for same. Fluid being pulled through the canister subassembly and intake enters the canister body at the tangential inlet
