Solution Overview

Problem

Existing overflow plate replacement systems are difficult to install, interfere with fluid flow, and are not universal in accommodating various shapes and sizes of overflow plates.

Innovation Solution

A device comprising an overflow plate cover with a retention plate that securely attaches to the bathtub wall, allowing for easy installation and concealment of overflow plates without obstructing fluid flow, and is designed to fit most overflow plate styles and sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a clip is used to attach the cover to the overflow plate, then the cover can be installed, but the clip may fail or loosen over time and obstruct the fluid opening

Engineering Contradiction:
Improvecover installationVSAvoidclip retention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The invention extracts the problematic clip component and replaces it with a retention plate that attaches directly to the bathtub wall. The retention plate has a lip that engages with the overflow plate's protrusion, eliminating the clip's retention function while preventing clip failure and obstruction issues.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The retention plate serves as an intermediary component between the bathtub wall and the overflow plate cover. It provides a stable mounting structure that secures the cover without obstructing fluid flow, resolving the contradiction between ease of installation and reliable retention.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Shape

If a supplemental cover is used to conceal the overflow plate, then the aesthetic appearance is improved, but the fluid flow rate may be decreased

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidfluid flow rate
Core Design Contradiction:
ShapeVSProductivity

Solution Approach 1:

The cover and retention plate are designed with localized openings that provide aesthetic coverage in most areas while maintaining unobstructed fluid flow paths. The opening in the retention plate aligns with the overflow plate's fluid opening, ensuring that the local quality of the cover provides appearance improvement without sacrificing overall fluid flow productivity.

Inventive Principle:
Principle #3Local quality

3Ease of repair

If traditional overflow plate replacement is attempted, then plumbing changes can be made, but the process is laborious and requires re-testing the plumbing system

Engineering Contradiction:
Improveplumbing modification capabilityVSAvoidinstallation time
Core Design Contradiction:
Ease of repairVSLoss of time

Solution Approach 1:

The invention segments the overflow system into modular components: the existing overflow plate, the retention plate, and the cover. This segmentation allows aesthetic modifications without disturbing the underlying plumbing system, enabling easy repair and replacement while eliminating time-consuming re-testing requirements.

Inventive Principle:
Principle #1Segmentation

4Ease of operation

If a clip-based cover system is used, then installation is possible, but the clip obstructs the fluid opening and decreases fluid flow rate

Engineering Contradiction:
Improvecover attachmentVSAvoidfluid flow rate
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The invention extracts the clip component entirely and replaces it with a retention plate that attaches to the bathtub wall. This elimination of the clip removes the obstruction to the fluid opening while maintaining cover attachment functionality, thus preserving fluid flow rate.

Inventive Principle:
Principle #2Taking out (Extraction)
