Solution Overview

Problem

Existing swimming pool designs, such as skimmer and infinity pools, face issues with maintenance complexity, hygiene, and high operational costs, with both types requiring compensation tanks and technical rooms that are difficult to maintain, and often result in dirty corners and inefficient water circulation.

Innovation Solution

A swimming pool structure with an edge zone featuring a top wall composed of inclined segments or tiles with grooves or porous material, integrated with a water collection, filtering, and recirculating circuit that allows water to flow from the main tank to a recessed area, eliminating the need for compensation tanks and enabling efficient water circulation and filtration without direct suction into the tank.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If skimmer pools are used with perimeter edge openings for water collection, then water circulation is achieved, but corners remain dirty and mixing is insufficient

Engineering Contradiction:
Improvewater circulation efficiencyVSAvoiddirty corners and stagnant water zones
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The pool perimeter is divided into multiple segments with individual skimmers distributed along the edge, ensuring comprehensive water collection from all areas including corners. This segmentation allows water to be drawn from multiple locations simultaneously, eliminating stagnant zones and improving overall circulation efficiency.

Inventive Principle:
Principle #1Segmentation

2Object-affected harmful factors

If infinity pools are used with overflow channels, then continuous water cleaning is achieved, but construction and operation costs are very high

Engineering Contradiction:
Improvecontinuous water cleaningVSAvoidconstruction and operation costs
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The invention extracts the essential function of infinity pools (continuous water cleaning) by using a simpler skimmer system with strategically positioned openings along the perimeter. This removes the need for expensive overflow channels and complex compensation tanks while maintaining effective water circulation and cleaning.

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If compensation tanks and technical rooms are added to both pool types, then water management is improved, but maintenance difficulty increases due to hygienic conditions

Engineering Contradiction:
Improvewater management efficiencyVSAvoidmaintenance difficulty
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The invention removes the need for separate compensation tanks and technical rooms by integrating water management functions directly into the pool structure. The skimmer system with perimeter openings allows direct water collection and filtration at the pool edge, eliminating hidden technical spaces that are difficult to maintain.

Inventive Principle:
Principle #2Taking out (Extraction)

4Speed

If direct suction into the tank is used for water circulation, then water flow is achieved, but stagnation areas form in corners

Engineering Contradiction:
Improvewater flow rateVSAvoidstagnation areas
Core Design Contradiction:
SpeedVSObject-affected harmful factors

Solution Approach 1:

Multiple skimmers are distributed along the pool perimeter, including corners and edges, to create multiple suction points. This segmentation ensures water flows from all areas simultaneously, preventing stagnation zones while maintaining efficient circulation speed throughout the entire pool volume.

Inventive Principle:
Principle #1Segmentation
