Solution Overview

Problem

Existing swimming pool installations with underground recovery tanks require dedicated ground space and excavation, increasing installation costs and impacting the aesthetic and functional layout.

Innovation Solution

Integrate buffer tubes for water storage around the perimeter of an in-ground or semi-in-ground swimming pool, supported by structural elements that also reinforce the pool, allowing simultaneous construction and burial, reducing space requirements and eliminating the need for separate excavation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If underground recovery tanks are used for water storage, then water storage capacity is achieved, but dedicated ground space is required and excavation work increases installation cost

Engineering Contradiction:
Improvewater storage capacityVSAvoidground space requirement
Core Design Contradiction:
Quantity of substanceVSArea of stationary object

Solution Approach 1:

The patent combines the pool support structure with the water storage tank structure. The tank is integrated into the pool construction by using the same excavation space and structural support elements, merging two separate functions (pool support and water storage) into a single unified system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The support structure serves dual purposes: it provides mechanical support for the swimming pool while simultaneously serving as the structural framework for the water storage tank. This multi-functionality eliminates the need for separate structures and reduces overall ground space requirements.

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

2Quantity of substance

If underground recovery tanks are used for water storage, then water storage capacity is achieved, but excavation and burial work increases installation cost

Engineering Contradiction:
Improvewater storage capacityVSAvoidinstallation cost
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

The patent merges the construction timelines and operations for both the pool and water storage system. By integrating the tank construction into the pool construction process, single excavation and burial operations serve both structures, reducing redundant work and installation costs.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The water storage tank is constructed simultaneously with the pool during the initial construction phase, rather than as a subsequent addition. This preliminary integration allows shared preparation work and eliminates the need for separate excavation and installation operations later.

Inventive Principle:
Principle #10Preliminary action

3Volume of stationary object

If buffer tubes are positioned around the pool basin, then space for water storage is optimized, but structural support requirements increase

Engineering Contradiction:
Improvewater storage volumeVSAvoidstructural support requirement
Core Design Contradiction:
Volume of stationary objectVSStrength

Solution Approach 1:

The support structure is designed to fulfill multiple roles: it provides mechanical support for the swimming pool basin while simultaneously serving as the structural framework for the water storage tank. This eliminates the need for additional dedicated support structures for the tank.

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

Solution Approach 2:

The patent merges the support functions for both the pool and water storage system into a single integrated structural framework. The same structural elements that support the pool also support the tank, optimizing material usage and structural efficiency.

Inventive Principle:
Principle #5Merging (Combining)
