Seal Surface Adapter for Toilet Flush Valves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gravity-operated flush toilets often experience water leakage due to damage or wear of the rim of the main flush valve orifice, requiring replacement of the entire flush valve assembly, which is time-consuming and messy.
Innovation Solution
A seal surface adapter with a ring-like structure and adhesive application to create a leak-proof seat for the flapper or tower valve, accommodating various flush valve assemblies and ensuring self-centering alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rim of the main flush valve orifice becomes damaged or worn, then the flapper fails to properly seal, but replacing the entire flush valve assembly is time-consuming and messy
Solution Approach 1:
The invention separates the sealing function from the entire flush valve assembly by introducing a standalone adapter ring that interfaces between the flush valve orifice and the flapper valve. This segmentation allows the sealing component to be replaced independently without replacing the entire assembly, thereby reducing installation time while maintaining sealing reliability.
Solution Approach 2:
The adapter ring acts as an intermediary component between the damaged flush valve orifice and the flapper valve. It provides a new sealing surface that mediates the connection, allowing the flapper to seal properly against the adapter rather than directly against the worn orifice, thus restoring sealing function without full assembly replacement.
2Reliability
If the rim of the main flush valve orifice becomes damaged or worn, then the flapper fails to properly seal, but replacing the entire flush valve assembly is complex and messy
Solution Approach 1:
By segmenting the sealing function into a separate adapter ring component, the invention simplifies the replacement process. Instead of dealing with the complex entire flush valve assembly, users only need to install the simple adapter ring, reducing installation complexity while restoring sealing reliability.
Solution Approach 2:
The adapter ring is designed as a simple, inexpensive component that can be easily replaced. Rather than investing in the complex and expensive full flush valve assembly replacement, users can opt for the affordable adapter ring that provides the necessary sealing function with minimal installation complexity.
3Reliability
If a new flush valve assembly is installed, then sealing may be improved, but improper installation creates additional problems
Solution Approach 1:
The adapter ring serves as a forgiving intermediary that simplifies the installation process. Its design with features like self-centering mechanisms and adhesive application surfaces makes it easier to install correctly compared to full flush valve assemblies, reducing the risk of improper installation while achieving reliable sealing.
Solution Approach 2:
The adapter ring incorporates self-centering features and simple adhesive-based installation that allow users to install it correctly without requiring specialized skills or tools. This self-service capability ensures proper installation while achieving the desired sealing reliability, eliminating the need for complex alignment procedures.

AI summary
An apparatus comprises a ring, a top portion, and a bottom portion. The apparatus further comprises a first leg and a second leg. In addition, the apparatus comprises a horizontal portion. The horizontal portion connects the first leg and the second leg. The legs and horizontal portion, together with an adhesive, overlay and sealingly engage the top rim of a flush valve wall, which is part of a toilet flush valve.
