Solution Overview

Problem

Existing pool deck lids for in-ground pools either visibly contrast with the deck or require separate inventory for aesthetic and functional sides, lacking a reversible solution that seamlessly integrates with the deck material.

Innovation Solution

A convertible lid assembly with a non-fillable and fillable side, featuring a common perimeter, sidewall, and mounting ring, allowing reversible installation and secure attachment using retaining screws, with integrated finger holes and non-slip surfaces for easy access and aesthetic integration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a plastic lid is used to cover the skimmer aperture, then the lid is cost-effective and easily visible, but the lid visibly contrasts with the deck and is aesthetically displeasing

Engineering Contradiction:
Improvecost-effectivenessVSAvoidaesthetic integration
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The lid is segmented into two distinct sides: a non-fill side for visibility and accessibility, and a fill side for aesthetic integration. This segmentation allows the same lid structure to serve both functional and aesthetic purposes by selecting which side faces upward during installation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The convertible lid assembly serves multiple functions: it can be installed with the non-fill side up for easy access and visibility, or with the fill side up for aesthetic integration with the deck. This multi-functionality eliminates the need for separate lid types for different aesthetic preferences.

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

2Adaptability or versatility

If a fillable container structure is used to match the deck material, then the lid provides seamless aesthetic integration, but the lid requires separate inventory for aesthetic and functional versions

Engineering Contradiction:
Improveaesthetic integrationVSAvoidinventory management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention merges the previously separate non-fill lid and fill lid into a single convertible lid assembly. By integrating both the non-fill side and fill side into one unified structure, the patent eliminates the need for manufacturers and retailers to maintain separate inventory for aesthetic and functional lid versions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The convertible lid assembly serves multiple functions: it can be installed with the non-fill side up for easy access and visibility, or with the fill side up for aesthetic integration with the deck. This multi-functionality eliminates the need for separate lid types for different aesthetic preferences.

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

3Ease of operation

If finger holes are provided for easy removal of the lid, then the lid is easily accessible, but the lid structure becomes more complex

Engineering Contradiction:
Improvelid accessibilityVSAvoidlid structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The lid design incorporates self-service features where the sidewall structure itself provides the finger holes for removal, rather than requiring separate complex mechanisms. The finger holes are formed by the natural geometry of the sidewall, eliminating the need for additional components.

Inventive Principle:
Principle #25Self-service

AI summary

A convertible lid for pool decks to cover access to the skimmer and any other plumbing and/or mechanics related to the pool. One side of the convertible lid is made of a plastic or other material that is easily liftable and recognizable as a lid cover. The other side is a fillable lid that can be filled with the same material as is used for the deck so that the lid blends into the deck and is not easily visible or recognizable. The single 10 lid can be used either way and is constructed to easily convert between the two types of coverings.
