Solution Overview
Problem
Existing swimming pool cleaners face issues with clogged filter elements, reduced suction performance, and difficulty in handling debris, leading to incomplete cleaning and maintenance challenges.
Innovation Solution
The introduction of a hydrocyclonic particle separator assembly and a drive system with six driven brushed rollers, which includes a canister subassembly with cyclone containers and a filtering medium to efficiently separate debris from the pool water, and a quick-release latch for easy maintenance access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional filter elements (bags, mesh, baskets) are used to trap debris, then debris containment is achieved, but the filter surface area becomes clogged quickly reducing suction performance
Solution Approach 1:
The filter assembly is segmented into multiple filter elements (first filter element, second filter element, third filter element) with different surface areas and positions. This segmentation allows debris to be distributed across multiple surfaces, preventing any single element from becoming completely clogged and maintaining suction performance while increasing total filtering capacity.
2Productivity
If filter elements are made larger to increase filtering capacity, then debris retention volume increases, but the cleaner becomes more complex and harder to maintain
Solution Approach 1:
Instead of using one large complex filter, the system uses multiple smaller filter elements arranged in a modular fashion. Each filter element can be independently accessed and maintained, reducing the complexity of individual components while achieving high total filtering capacity through their combined surface area.
Solution Approach 2:
The filter elements are arranged within the canister body in a nested configuration where the first filter element is positioned at a first position, the second filter element at a second position, and the third filter element at a third position. This nested arrangement maximizes the use of available space within the canister, increasing filtering capacity without significantly increasing the overall device footprint or complexity.
3Productivity
If the cleaner traverses pool surfaces to clean debris, then cleaning coverage is improved, but obstacles cause the cleaner to get stuck resulting in partial cleaning
Solution Approach 1:
The pool cleaner is designed with universal navigation capabilities that allow it to traverse various pool surfaces including floors, walls, and waterline areas. The drive system and roller configuration enable the cleaner to adapt to different pool geometries and obstacle types, maintaining cleaning completeness across diverse pool environments rather than being limited to specific cleaning paths.
4Reliability
If filter elements are cleaned or replaced frequently to maintain performance, then suction performance is preserved, but maintenance time and user handling of debris increases
Solution Approach 1:
The system is designed so that the third filter element, positioned to receive debris from the pump system, acts as a preliminary filter that captures debris before it reaches the main filter elements. This preliminary action prevents the main filters from becoming clogged as quickly, extending the time between maintenance operations while maintaining suction performance.
Solution Approach 2:
The segmented filter element design allows for selective maintenance where only the most heavily soiled filter elements need to be cleaned or replaced at any given time, rather than requiring complete disassembly and cleaning of the entire filter assembly. This reduces maintenance time and minimizes user handling of debris.
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 filtering operation and traversal through the pool, ensuring thorough cleaning and reducing maintenance efforts by effectively separating debris and improving the pool cleaner's operational efficiency.
Implementation Method 1
Fluid entering the one or more cyclone containers forms a cyclonic flow about a second axis within each cyclone container. The second cyclonic flow includes once-filtered debris-laden fluid having small debris that is separated from the fluid through contact with the cyclone container body.
Implementation Method 2
The cyclone containers each include a body having a tangential inlet, a fine debris underflow nozzle, and an overflow opening. Fluid entering the one or more cyclone containers forms a cyclonic flow about a second axis within each cyclone container.
Implementation Method 3
The filtering medium is positioned within the canister, the one or more cyclone containers are positioned within the filtering medium. A portion of the first cyclonic flow is pulled across the filtering medium and into one or more cyclones containers.
Implementation Method 4
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 forming a cyclonic flow about a first axis within the canister body.
Implementation Method 5
A motor housing includes a pump motor operatively connected to an impeller for same.
