Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swimming pool cleaners face issues with filter clogging, reduced suction performance, and difficulty in navigating around obstacles, leading to incomplete cleaning and manual debris handling.
Innovation Solution
The introduction of a swimming pool cleaner equipped 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 separate debris efficiently and a quick-release latch for easy maintenance, allowing for effective debris separation and navigation over various pool surfaces.
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 and suction performance is reduced
Solution Approach 1:
The patent replaces the traditional mechanical filtration system (bags, mesh, baskets) with a hydrocyclonic separation system that uses centrifugal force generated by cyclonic chambers to separate debris from water. This substitution eliminates the clogging issue inherent in mechanical filters while maintaining effective debris containment and preserving suction performance throughout the cleaning cycle.
Solution Approach 2:
The patent employs hydrocyclonic action, utilizing water pressure and centrifugal force to create rotating flow patterns within cyclonic chambers. This hydraulic mechanism separates debris particles from the water stream based on density and size, allowing continuous operation without the clogging problems that plague traditional mechanical filter systems.
2Reliability
If traditional filter elements are used, then debris is trapped, but manual handling and cleaning of the filter elements is required
Solution Approach 1:
The hydrocyclonic separation system is self-cleaning by design. The centrifugal force generated in the cyclonic chambers continuously throws debris particles outward to the chamber walls where they are collected and periodically discharged automatically. This eliminates the need for manual filter cleaning or replacement, as the system maintains itself during operation.
3Productivity
If the cleaner encounters obstacles (lights, drains) during cleaning, then cleaning coverage is achieved, but the cleaner gets stuck and cleaning is incomplete
Solution Approach 1:
The patent employs six independently controllable driven rollers that can dynamically adjust their rotation speeds and directions. This dynamic control system enables the cleaner to navigate around obstacles by selectively varying the speed and direction of individual rollers, allowing the device to maintain cleaning completeness by avoiding entrapment while still achieving comprehensive pool surface coverage.
4Adaptability or versatility
If six driven brushed rollers are used for navigation, then traversal through the pool is improved, but the drive system complexity increases
Solution Approach 1:
The drive system is segmented into six independent roller units, each with its own drive mechanism. This segmentation allows each roller to be controlled independently, providing superior navigation capability around obstacles. While this increases component count, the modular nature of the segmented design simplifies maintenance and allows for more flexible control strategies compared to a single complex drive system.
