Modular Sink Stopper and Strainer for Universal Drain Fit and Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sinks with varying drain sizes and shapes present a challenge for universal sink stoppers and strainers, as existing solutions often fail to provide a secure and effective fit across different configurations.
Innovation Solution
A modular sink stopper and strainer system comprising a handle, gasket, plates, and a container with a biocide, where the gasket forms a partial seal with the drain and the handle's rotation aligns holes to control liquid flow, while the biocide is slowly dissolved to clean the drain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal sink stopper design is used, then adaptability to different sink configurations is improved, but securing a reliable seal and effective liquid flow control becomes difficult
Solution Approach 1:
The sink stopper system is divided into multiple independent components: a stopper body, a strainer assembly, a linkage mechanism, and a lift rod. This segmentation allows each component to be optimized for its specific function while working together to achieve universal adaptability and reliable performance across different sink configurations
Solution Approach 2:
The sink stopper assembly is designed with a universal configuration that can fit various drain sizes and shapes. The strainer assembly includes an adjustable collar and multiple mounting options, while the stopper body features a universal sealing mechanism that adapts to different drain geometries, enabling one design to serve multiple sink types
2Ease of manufacture
If the sink stopper components are made modular for easy assembly, then ease of installation is improved, but the complexity of ensuring proper alignment and sealing increases
Solution Approach 1:
The linkage mechanism employs an asymmetric design where the lever arm lengths and pivot point positions are specifically configured to provide mechanical advantage. This asymmetric geometry ensures that when the user lifts the handle, the force is automatically directed to properly align and press the stopper against the drain, simplifying the assembly process while maintaining reliable sealing
Solution Approach 2:
A collar or adapter component serves as an intermediary element between the strainer assembly and the drain. This intermediary component provides a standardized interface that simplifies modular assembly while ensuring proper alignment and sealing, bridging the gap between the modular components and the varying drain configurations
