Removable Drain Strainer Cartridge for Easy Debris Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bathroom sink drain stopper mechanisms often misalign, leading to clogging issues due to hair and foreign objects, and the strainer assemblies are difficult to access for cleaning and replacement.
Innovation Solution
A stopper assembly with a removable strainer cartridge that allows for efficient, sanitary replacement of the strainer element, featuring a stopper head with a seal and a detachable strainer that can be released without contact, and a stopper body with a supplemental strainer device for downstream debris capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional strainer assembly is installed in the drain system, then debris can be captured, but the strainer becomes difficult to access for cleaning and replacement
Solution Approach 1:
The stopper assembly is divided into separate components: the stopper head, the strainer, and the stopper body. The strainer is detachably coupled to the stopper head, allowing it to be removed independently for cleaning or replacement without disassembling the entire drain system. This segmentation enables easy maintenance while maintaining effective debris capture during normal operation.
2Reliability
If the strainer is permanently attached to the stopper head, then debris capture is effective, but replacement requires disassembling the drain system
Solution Approach 1:
The coupling between the strainer and stopper head is designed to be dynamic rather than static. The strainer can be selectively attached and detached from the stopper head through a simple operation. This dynamic coupling allows the strainer to remain securely in place during operation for effective debris capture, while enabling easy removal and replacement when needed without complex disassembly.
3Stability of the object's composition
If the stopper head is permanently fixed to the stopper body, then the assembly is stable, but maintenance requires full disassembly
Solution Approach 1:
The stopper assembly is segmented into the stopper head and stopper body as separate, detachable components. The stopper head can be removed from the stopper body by rotating it to a release angle, providing stable operation during use while allowing easy access to the strainer for maintenance without requiring complete disassembly of the drain system.
4Reliability
If conventional strainer assemblies are used, then debris is captured, but cleaning requires contact with contaminated surfaces
Solution Approach 1:
The stopper head acts as an intermediary component that can be detached from the stopper body. This allows the strainer to be removed and cleaned in a separate location away from the drain system, reducing exposure to contaminated surfaces and water during the cleaning process while maintaining effective debris capture when installed.

AI summary
A stopper assembly for a drain system of a fluid basin is provided. The stopper head assembly includes a stopper head having a seal to sealingly engage the drain system of the fluid basin when the stopper assembly is moved from a drain position to a plug position and a strainer to strain fluid passing through the drain system when the stopper head is in a drain position. The stopper head assembly further includes a stopper body operably coupleable to a control element to move the assembly between the drain position and the plug position. The stopper body may be detachably coupled to the stopper head and/or the strainer to enable selective removal of the stopper head and the strainer from the stopper body when the stopper body is installed for use and coupled to the control element. Related methods, systems and components are also provided.
