Solution Overview

Problem

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

Innovation Solution

An above-ground pool band-frame connector device that secures vertical frame members to the band and liner externally, minimizing gaps and enhancing stability by using coupling devices and cradles to maintain a secure, stable configuration.

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-free structure
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The patent introduces an intermediary component (the band-frame connector device) that couples the vertical frame member to both the band and the liner. This connector acts as a mediator that distributes the forces and maintains contact between the band and liner, preventing gaps from forming while preserving the structural support function.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the band is positioned to support the pool when filled with water, then structural stability is improved, but gaps form between the band and liner compromising safety

Engineering Contradiction:
Improvepool stabilityVSAvoidgaps as stepping hazards
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The band-frame connector device serves as an intermediary that maintains the stabilizing function of the band while eliminating the harmful gaps. The connector ensures continuous contact between the band and liner, preserving pool stability while removing the safety hazard of gaps that could be perceived as stepping surfaces.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Force

If vertical frame members press against the band when the pool is filled, then water weight is supported, but gaps form between the band and the liner

Engineering Contradiction:
Improvewater weight supportVSAvoidgap-free assembly
Core Design Contradiction:
ForceVSManufacturing precision

Solution Approach 1:

The connector device acts as an intermediary that transmits the force from the vertical frame member to both the band and the liner simultaneously. This ensures that the water weight is properly supported while maintaining precise contact between the band and liner, eliminating gaps that would otherwise form due to the pressing action.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Embodiments of present disclosure provide an above-ground pool and an above-ground pool band-frame connector device. The above-ground pool includes a pool liner and a band connected to the exterior of the pool liner. Furthermore, the above ground pool includes an above-ground pool frame with a plurality of above-ground pool horizontal frame members and a plurality of above-ground pool vertical frame members. The above-ground pool frame can be coupled with the pool liner. The above-ground pool further includes a first above-ground pool band-frame connector device, wherein the first above-ground pool band-frame connector device couples a first of the plurality of above-ground pool vertical frame members to the band.
