Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pool cleaning methods are inefficient and ineffective, requiring excessive physical effort for hand-held skimmers and offering poor filtration with motor-driven electric pool skimmers due to large filter hole diameters.
Innovation Solution
A modular pool cleaner design featuring a first and second filter assembly with detachable housings, a water pump, and a floating component, allowing for sequential filtration and easy maintenance, with filter holes of varying sizes to handle large and small debris effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hand-held skimmer is used to clean up wastes, then the cleaning process can be performed manually, but it consumes plenty of physical strength and requires long cleaning time resulting in low efficiency
Solution Approach 1:
The patent replaces manual mechanical skimming with an automated water circulation system. A pump draws water from the pool, passes it through filter assemblies with varying pore sizes to capture wastes, and returns the cleaned water to the pool. This substitution eliminates manual labor while significantly improving cleaning efficiency through continuous automated operation.
2Productivity
If a motor-driven electric pool skimmer is used, then automated cleaning is achieved, but the filter basket or mesh has large filter hole diameters resulting in poor filtration effect
Solution Approach 1:
The patent divides the filtration system into multiple filter assemblies arranged in series, each with different filter pore diameters. The first filter assembly has larger pores to capture coarse debris, while the second filter assembly has smaller pores to capture finer particles. This segmented approach enables both high automated cleaning efficiency and precise filtration without requiring a single complex filter.
Solution Approach 2:
Different sections of the filtration system are designed with locally optimized filter pore sizes. The first filter assembly uses larger pores suitable for initial coarse filtration, while the second filter assembly uses smaller pores for fine filtration. This local quality differentiation allows each section to perform its specific function optimally, achieving both high productivity and high filtration precision.
3Device complexity
If a single filter assembly is used in the pool cleaner, then the device structure is simple, but the filtration effect is insufficient and the device cannot be easily maintained
Solution Approach 1:
The filtration system is segmented into multiple detachable filter assemblies that can be connected in series. Each assembly contains filters with different pore sizes, and the assemblies can be easily detached and reattached. This segmentation maintains relative structural simplicity while dramatically improving filtration effectiveness and enabling easy maintenance through individual assembly replacement.
Solution Approach 2:
The filter assemblies are designed with detachable connections that allow dynamic reconfiguration. Users can easily detach, clean, or replace individual filter assemblies without disassembling the entire system. This dynamic design maintains operational simplicity while improving filtration performance and facilitating easy maintenance.
4Volume of moving object
If the filter components are integrated into a single housing, then the device structure is compact, but maintenance requires complete disassembly and replacement of all components
Solution Approach 1:
The device uses modular filter assemblies that can be detached from the housing independently. When maintenance is needed, only the specific filter assembly requiring service needs to be detached and replaced, not the entire device. This segmentation maintains a relatively compact overall structure while dramatically simplifying maintenance procedures.
Solution Approach 2:
The design allows individual filter assemblies to be easily discarded (removed) and replaced without affecting other components. Used filter assemblies can be recovered, cleaned or replaced independently, minimizing waste of functional components and reducing maintenance time and effort.
