Solution Overview

Problem

Conventional above-ground pools suffer from gaps forming between the band and the liner when filled with water, compromising structural integrity and user safety.

Innovation Solution

An above-ground pool design that incorporates a band-frame connector device to securely couple vertical frame members to the band and pool liner, eliminating gaps and enhancing stability by securing the frame members externally to both the band and liner.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If vertical frame members are threaded between the liner and the band in conventional above-ground pools, then the pool structure is supported, but gaps form between the band and the liner when filled with water

Engineering Contradiction:
Improvestructural supportVSAvoidgap formation
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The patent introduces a connector as an intermediary element that couples the vertical frame member to both the band and the liner. This connector ensures continuous contact between the band and liner by mechanically linking them through the frame member, thereby preventing gap formation while maintaining structural support.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the frame members are disconnected and reconnected during disassembly and reinstallation, then the pool can be moved and maintained, but the connection between the band and liner may become less secure

Engineering Contradiction:
Improvedisassembly and reassemblyVSAvoidconnection security
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The connector is designed as a separate, modular component that can be easily attached and detached from the frame members, band, and liner. This segmentation allows for simple disassembly and reassembly while maintaining secure connections through dedicated coupling mechanisms such as slots, protrusions, or fasteners.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If no connector device is used and frame members are simply placed between band and liner, then the device complexity is reduced, but gaps form compromising structural integrity

Engineering Contradiction:
Improveconnector deviceVSAvoidstructural integrity
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

The connector serves as a simple intermediary component that provides direct mechanical coupling between the frame member and the band-liner assembly. This straightforward coupling mechanism maintains structural integrity without introducing complex systems, using basic elements like slots, protrusions, or fasteners.

Inventive Principle:
Principle #24Intermediary (Mediator)
