Dual-Function Drain Cover for Plug and Strainer Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drain covers are complex, difficult to position, remove, clean, and replace, and lack the functionality of both a plug and a strainer, often becoming clogged due to debris accumulation.
Innovation Solution
A drain cover with a single component featuring a positioning member with multiple openings and a resilient sealing member that can be easily positioned, removed, and cleaned, functioning as both a plug and a strainer by adjusting its configuration to allow or block fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a drain cover uses a single component design, then ease of operation and ease of manufacture are improved, but functionality (providing both plug and strainer capabilities) deteriorates
Solution Approach 1:
The patent combines the plug function and strainer function into a single integrated drain cover component. The positioning member with multiple openings provides strainer functionality while the resilient sealing member provides plug functionality, eliminating the need for separate components and simplifying operation.
Solution Approach 2:
The single drain cover component is designed to perform multiple functions: it acts as a strainer when the resilient sealing member is retracted, allowing water flow through the positioning member openings, and acts as a plug when the resilient sealing member expands to contact and seal against the positioning member, blocking all flow.
2Adaptability or versatility
If a drain cover uses multiple movable components to provide plug and strainer functions, then adaptability is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent merges multiple functional components into a single integrated unit. The positioning member and resilient sealing member form one cohesive drain cover assembly that provides both strainer and plug functions, reducing the number of separate movable components and simplifying the overall device structure.
3Ease of manufacture
If a drain cover uses a single component design, then ease of manufacture and ease of operation are improved, but cleaning accessibility deteriorates
Solution Approach 1:
The drain cover is segmented into two main parts: the positioning member with multiple openings and the resilient sealing member. This segmentation allows the resilient sealing member to be independently removed from the positioning member, providing easy access for cleaning both components separately while maintaining the simplicity of a single integrated design during normal operation.
4Adaptability or versatility
If a drain cover uses traditional multi-component design, then functionality is improved, but productivity and ease of operation deteriorate
Solution Approach 1:
The patent combines plug and strainer functions into one integrated drain cover component that can be quickly installed or removed as a single unit. The resilient sealing member automatically engages with the positioning member upon installation, providing immediate functionality without requiring separate assembly steps, thus improving installation and removal speed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The drain cover is easily positionable, removable, cleanable, and replaceable, effectively preventing clogging by allowing water to pass while blocking debris, thus simplifying maintenance and functionality.
Implementation Method 1
a resilient sealing member connected to the positioning member at a center point, the resilient sealing member including a rim arranged concentrically about the center point. The rim contacts the positioning member to prevent fluid from passing through the plurality of openings in a closed position. The rim does not contact the positioning member to allow fluid to pass through the plurality of openings in an open position.
