Modular Pool Vacuum with Dual Filtration and Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current swimming pool vacuum cleaners, both autonomous and conventional, fail to effectively remove fine and volatile debris, leading to water clouding and filter clogging issues, and existing solutions for large-scale removal are either not universal or excessively water-consuming.
Innovation Solution
A submersible vacuum cleaner with a modular design featuring a suction turbine, electric motor, pre-filter, and a versatile discharge outlet that can connect to a pipe or a finer filter cartridge, allowing for classic filtration, additional filtration, or direct discharge into the sewer, reducing water consumption and operational limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fine filter is used to capture fine deposits, then filtration effectiveness is improved, but the filter quickly becomes clogged requiring multiple washings
Solution Approach 1:
The filtration system is segmented into two distinct filters: a pre-filter for coarse debris and a fine filter for fine particles. This segmentation allows each filter to operate at optimal capacity without the other becoming clogged, eliminating the need for frequent washings while maintaining high filtration effectiveness.
Solution Approach 2:
The pre-filter performs preliminary filtration of coarse debris before water enters the fine filter. This preliminary action protects the fine filter from rapid clogging by removing larger particles first, allowing the fine filter to maintain its capture effectiveness for extended periods.
2Ease of operation
If conventional filtration is used, then operational simplicity is maintained, but fine particles are released back into the pool causing water clouding
Solution Approach 1:
The two-stage filtration system acts as an intermediary between simple conventional filtration and complex filtration systems. The pre-filter handles coarse debris while the fine filter captures fine particles, together eliminating water clouding while maintaining operational simplicity through a straightforward sequential filtration process.
3Productivity
If pool filter pump is used for sewerage, then discharge capacity is improved, but water consumption increases significantly
Solution Approach 1:
Instead of using the high-capacity pool filter pump that discharges excessive water, the invention uses a garden hose at partial capacity. This provides sufficient discharge capability for vacuum operation while dramatically reducing water consumption compared to using the main pool filtration system.
4Adaptability or versatility
If a modular design with multiple attachments is used, then versatility is improved, but device complexity increases
Solution Approach 1:
The discharge outlet is designed with a universal connector that can accommodate both the sewer hose attachment and the fine filter cartridge. This single universal interface provides multiple functions (sewer discharge, fine filtration, or both combined) without requiring separate complex attachment mechanisms, thereby maintaining structural simplicity while achieving functional versatility.
