Drain Strainer Filtration With Spring-Loaded Debris Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drain strainers fail to prevent all hair and objects from entering the drain and require users to manually remove collected debris, which is undesirable due to hygiene concerns.
Innovation Solution
A drain strainer with a basket and perforations that collects debris, preloaded to a potential energy state, converting to kinetic energy upon release to eject debris without user contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a drain strainer with perforations is used to filter hair and objects, then debris collection is improved, but manual removal of debris becomes necessary which creates hygiene issues
Solution Approach 1:
The invention extracts the debris removal function from manual handling by users. A spring-loaded ejection mechanism is integrated into the strainer device that automatically propels collected debris out of the basket through a discharge opening, eliminating the need for users to manually contact and remove hair and objects from the strainer.
Solution Approach 2:
The strainer device performs self-service by automatically ejecting its own collected debris. The spring mechanism is activated by the user pressing a button or releasing a latch, causing the basket to rapidly expand or contract and expel the accumulated hair and objects without requiring user contact with the debris itself.
2Reliability
If traditional strainers are used, then some hair is prevented from entering drain, but not all hair and objects are caught
Solution Approach 1:
The strainer is divided into a basket portion with numerous perforations that filters debris from water, and a separate ejection mechanism portion. The basket can be made of flexible material that allows it to expand and contract during the ejection process, separating the filtration function from the disposal function while maintaining overall device integration.
Solution Approach 2:
The basket is constructed from flexible material that can dynamically change its volume and shape. During normal operation, the basket maintains its filtered state; during ejection, the basket rapidly expands or contracts to propel debris outward, providing adaptive functionality without requiring complex mechanical structures.
3Device complexity
If manual debris removal is required, then device simplicity is maintained, but user contact with waste objects is necessary
Solution Approach 1:
The spring-loaded mechanism acts as an intermediary between the collected debris and the external environment. Instead of requiring direct user contact with waste objects, the mechanical ejection system mediates the removal process by propelling debris through a discharge opening away from the user's hands and into a trash container or away from the drain area.
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
Effectively prevents hair and objects from entering the drain and allows for easy, hygienic disposal of collected debris without direct user contact.
Implementation Method 1
The drain strainer is configured to be preloaded to a potential energy state and upon the drain strainer being released from the potential energy state the potential energy converts to kinetic energy that is sufficient to eject the debris from the basket.
Data Source
AI summary
A drain strainer is provided that includes a basket. The basket defines a central cavity and includes perforations that are sized to enable liquid to drain through the basket while debris is collected in the basket. The drain strainer is configured to be preloaded to a potential energy state and upon the drain strainer being released from the potential energy state the potential energy converts to kinetic energy that is sufficient to eject the debris from the basket.
