Drain Closure Gasket Geometry for Universal Tub Shoe Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drain closure gaskets for bathtubs and sinks lack adaptability to varying tub drain shoe sizes and depths, requiring multiple gaskets and o-rings to achieve a proper seal, which complicates installation and compatibility.
Innovation Solution
A gasket with a unique construction featuring a vertical top portion and angled bottom portion, along with concentric annular platforms, allows for adjustable compression and fitment over different tub drain shoe sizes, providing a universal seal with a single gasket design that accommodates various tub drain shoe dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional drain closure gaskets are used, then multiple gaskets and o-rings are required to achieve a proper seal, but this complicates installation and compatibility
Solution Approach 1:
The patent combines multiple sealing components (gasket and o-rings) into a single integrated gasket structure. The gasket includes a body with an o-ring groove that receives an o-ring, effectively merging the functions of separate gaskets and o-rings into one unified component that provides the same sealing reliability with simplified installation
Solution Approach 2:
The gasket is designed with universal adaptability to fit various tub drain shoe sizes and configurations. The adjustable compression mechanism and standardized o-ring groove design allow a single gasket type to serve multiple sealing applications, replacing the need for multiple different gasket and o-ring combinations
2Adaptability or versatility
If multiple gaskets and o-rings are used to accommodate varying tub drain shoe sizes, then seal adaptability is achieved, but product versatility is reduced
Solution Approach 1:
The gasket design incorporates universal features including an adjustable compression mechanism and a standardized o-ring groove that can accommodate various drain shoe sizes and configurations. This allows a single gasket design to provide adaptability across different applications, eliminating the need for multiple specialized gasket variants
Solution Approach 2:
The gasket includes an adjustable compression mechanism that allows the sealing surfaces to be dynamically adjusted during installation to fit different tub drain shoe sizes and depths. This dynamic adjustment capability provides seal adaptability without requiring multiple fixed-size gasket options
3Ease of operation
If conventional gasket designs are used, then installation is simplified, but compatibility with different tub drain shoe dimensions is limited
Solution Approach 1:
The gasket is designed with universal compatibility features including an adjustable compression mechanism and standardized o-ring groove that work across different tub drain shoe sizes and configurations, maintaining ease of installation while expanding compatibility to various dimensions
Solution Approach 2:
The adjustable compression mechanism allows the gasket to be dynamically adapted during installation to fit different tub drain shoe dimensions, providing both ease of operation and broad compatibility without requiring complex installation procedures

AI summary
An exemplary embodiment, among others, of the present disclosure is directed to a drain closure assembly. Such an assembly has a domed cap at a top portion of the drain closure assembly and a flange that is positioned below the domed cap. The assembly further includes a stem that extends from below the flange to a bottom portion of the drain closure assembly and a gasket seal that is positioned around the stem at a bottom of the drain closure assembly. The gasket seal has a frusto-conical shape, wherein a top portion of the gasket seal has a wider diameter than a bottom portion of the gasket seal, and the gasket seal has a central circular opening that fits closely around the stem.
