Solution Overview

Problem

Existing methods for constructing artificial pools, especially natural-looking ones, face issues with algae formation and sand rot, leading to unsuitable conditions for swimming and potential harm from chemical purifiers.

Innovation Solution

A method involving a layered construction with a clay-based sealing layer, a granular separation layer, and geotextile layers, combined with a drainage system connected to a water recovery reservoir, minimizes water stagnation and prevents sand degradation, using a mineral stabilization layer and geotextile layers for filtration and protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If sand is used to create a natural appearance in artificial basins, then the aesthetic quality is improved, but the sand deteriorates and turns black due to stagnation and algae formation

Engineering Contradiction:

Improvenatural appearanceVSAvoidsand stability

Core Design Contradiction:

ShapeVSReliability

Solution Approach 1:

The basin bottom is divided into multiple functional layers: a drainage layer for water removal, a geotextile barrier layer to prevent sand infiltration, and a sand layer for aesthetic purposes. This segmentation allows each layer to perform its specific function, preventing sand deterioration while maintaining natural appearance.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A geotextile material is introduced as an intermediary layer between the drainage system and the sand layer. This geotextile acts as a barrier that prevents sand particles from mixing with the drainage water and accumulating in degradation-prone conditions, while still allowing water to pass through.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If chemical purifiers are used to destroy algae and microorganisms, then water purification is improved, but harmful effects are generated for bathers and animal species

Engineering Contradiction:

Improvewater purificationVSAvoidchemical harm

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The invention converts the natural stagnation problem into a beneficial natural filtration system. The layered construction with drainage and geotextile layers creates conditions that promote natural water circulation and biological filtration, eliminating the need for harmful chemical purifiers while maintaining effective water purification.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The basin system performs self-purification through its engineered layered structure. The drainage layer removes stagnant water, the geotextile layer filters particles, and the overall system promotes natural water circulation that prevents algae formation without requiring external chemical interventions.

Inventive Principle:

Principle #25Self-service

3Ease of manufacture

If water stagnation occurs in artificial basins, then construction simplicity is maintained, but algae formation increases and deteriorates the basin appearance

Engineering Contradiction:

Improveconstruction simplicityVSAvoid algae formation

Core Design Contradiction:

Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A drainage system is integrated into the basin construction to actively remove stagnant water. This hydraulic system prevents water accumulation that would lead to algae formation, while the overall construction remains relatively simple and compatible with traditional basin building methods.

Inventive Principle:

Principle #29Pneumatics and hydraulics
