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

VSEngineering 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

Engineering Contradiction:
Improvefiltration finenessVSAvoidoperational continuity
Core Design Contradiction:
Measurement precisionVSProductivity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
Improveoperational simplicityVSAvoidwater clouding
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If pool filter pump is used for sewerage, then discharge capacity is improved, but water consumption increases significantly

Engineering Contradiction:
Improvedischarge capacityVSAvoidwater consumption
Core Design Contradiction:
ProductivityVSQuantity of substance

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.

Inventive Principle:
Principle #16Partial or excessive action

4Adaptability or versatility

If a modular design with multiple attachments is used, then versatility is improved, but device complexity increases

Engineering Contradiction:
Improvefunctional versatilityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)
