Magnetic Sink Strainer Captures Magnetic Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sink strainers fail to prevent magnetic objects from being lost down the drain while allowing non-magnetic substances to flow freely, leading to object loss and potential plumbing damage.
Innovation Solution
A magnetic sink strainer with a base member, magnetic receiving regions, and embedded magnets that create a strong magnetic field to attract and retain magnetic objects, while slits allow non-magnetic substances to pass through, and legs secure the strainer in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional sink strainer is used, then non-magnetic substances can flow freely through the drain, but magnetic objects cannot be retained and are lost down the drain
Solution Approach 1:
The patent combines the strainer function with a magnetic field generation function into a single device. The magnetic receiving region is integrated into the strainer body, allowing the device to both filter non-magnetic substances and retain magnetic objects simultaneously, resolving the contradiction between object retention and device complexity.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary mechanism to differentiate between magnetic and non-magnetic objects. The magnetic receiving region generates a magnetic field that selectively interacts with magnetic objects, enabling retention of magnetic items while allowing non-magnetic substances to pass through freely.
2Reliability
If magnets are embedded in the strainer to capture magnetic objects, then magnetic objects are retained, but the strainer structure becomes more complex
Solution Approach 1:
The patent divides the strainer into distinct functional regions: a magnetic receiving region containing embedded magnets for capturing magnetic objects, and a non-magnetic region with slits for allowing fluid flow. This segmentation allows each region to perform its specific function efficiently while maintaining overall structural simplicity.
Solution Approach 2:
The patent applies magnetic properties locally to specific regions of the strainer rather than making the entire strainer magnetic. The magnets are embedded only in the magnetic receiving region, creating a localized magnetic field that captures magnetic objects without interfering with the fluid flow through non-magnetic regions.
3Reliability
If the strainer is designed to fit securely in the drain, then the strainer remains in place, but the structure requires additional components like legs
Solution Approach 1:
The patent combines the mounting function with the strainer body by integrating legs directly into the strainer structure. The legs are formed as part of the strainer body rather than being separate attachment components, allowing the device to secure itself in the drain while maintaining structural simplicity.

Data Source
AI summary
The present invention provides a magnetic sink strainer with at least one magnet securely attached to the strainer, to create a magnetic field. The invention also provides a magnetic sink strainer made of a magnetized material to provide a magnetic field. The magnetic sink strainer is firmly placed over a standard sink drain and functions to capture and retain objects that are attracted by a force as a result of being subjected to the magnetic field. This prevents such objects from accidentally being discarded into the sink drain. The magnetic sink strainer also includes at least one slit to enable fluids and other non-magnetic substances to easily and rapidly flow down to the sink drain.
