Waste Water Strainer Flange Cover With Resilient Ring Insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strainers in plumbing systems are difficult to remove and replace due to tarnished or aesthetically incompatible flanges, and conventional tools are insufficient for removal, with potential thread incompatibility issues and loss of the back drain system when removed.
Innovation Solution
A waste water insert with a cylindrical wall and flange is designed to be superimposed over the existing strainer flange, using a lip for centering and resilient ring members for secure engagement without requiring tools, allowing easy installation and compatibility with varying thread sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional tools are used to remove the existing strainer, then the strainer can be removed, but the removal process is difficult and time-consuming
Solution Approach 1:
The invention extracts the essential function of the strainer (flange engagement with the receptacle) and separates it from the valve assembly. By providing a standalone flange adapter that threads directly into the receptacle, the removal difficulty is eliminated while maintaining the strainer's functional purpose.
Solution Approach 2:
The invention divides the strainer system into separate functional components: the flange adapter (which provides engagement with the receptacle) and the valve assembly. This segmentation allows the flange to be independently replaced without removing the entire strainer system, greatly easing operation and reducing time loss.
2Ease of repair
If the existing strainer is removed to replace the flange, then the flange can be replaced, but the back drain system falls away and is lost
Solution Approach 1:
The flange adapter serves as an intermediary component that maintains the connection between the receptacle and the back drain system. By threading directly into the receptacle, it provides a stable mounting point that prevents the back drain system from falling away during flange replacement, eliminating material loss while enabling easy repair.
3Adaptability or versatility
If a substitute flange is threadably secured to the original strainer, then the flange can be replaced, but thread size incompatibility prevents proper installation
Solution Approach 1:
The flange adapter is designed with a universal threading interface that directly engages with the receptacle, making it compatible across different strainer configurations. This universal design eliminates thread size incompatibility issues and allows the same adapter to work with various strainer types, enhancing adaptability while reducing device complexity.
4Ease of operation
If conventional removal methods are used, then the strainer can be removed, but special tools and skilled labor are required
Solution Approach 1:
The flange adapter is designed to be self-installing through simple threading into the receptacle, requiring no special tools or skilled labor. The straightforward threaded connection allows homeowners to perform the installation themselves, greatly easing operation while reducing the skill level required.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy and secure installation of the waste water insert over the existing strainer without removing it, ensuring compatibility and maintaining the back drain system integrity.
Implementation Method 1
one or more grooves are positioned within the cylindrical wall of the insert that receive one or more resilient ring members that engage the cylindrical wall of the strainer

AI summary
A waste water insert has a cylindrical wall surrounding a vertical cylindrical bore. A horizontal flange extends outwardly from the upper end of the wall and has a lip formed on its outer periphery. The horizontal flange of the waste water insert is super-imposed over the horizontal flange of a waste water strainer located in a bathtub, sink or the like. The cylindrical wall of the insert extends downwardly through the cylindrical wall of the waste water strainer with the two walls being spaced from each other by virtue of the cylindrical wall of the insert having a smaller diameter than that of the strainer. One or more grooves are within the cylindrical wall of the insert and receive resilient rings that engage the cylindrical wall of the strainer.
