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, preloads potential energy, and converts it to kinetic energy for ejecting waste without direct user contact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional drain strainer is used, then hair and objects are collected in the strainer, but the user must manually remove the debris using their fingers which is disgusting and undesirable

Engineering Contradiction:
Improveease of waste removalVSAvoidhygiene contamination
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a plunger as an intermediary tool that allows the user to remotely eject debris from the strainer basket without direct hand contact. The plunger pushes the accumulated hair and objects out through the drain opening, eliminating the need for users to touch disgusting debris with their fingers while still achieving effective waste removal

Inventive Principle:
Principle #24Intermediary (Mediator)

2Strength

If the strainer basket is made rigid to maintain structural integrity, then it can effectively filter debris, but it cannot be flexed to eject the collected waste

Engineering Contradiction:
Improvestructural integrityVSAvoidwaste ejection capability
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The patent makes the strainer basket dynamically flexible rather than rigid. The basket is designed to be flexed by the plunger, allowing it to deform and push accumulated debris out through the drain opening. This flexibility enables the basket to adapt its shape for waste ejection while maintaining sufficient structural integrity to perform filtration when in its normal position

Inventive Principle:
Principle #15Dynamics

3Reliability

If the strainer uses a plug type design with holes, then it prevents most hair from passing through, but some hair and objects still escape and it requires finger contact for cleaning

Engineering Contradiction:
Improvefiltration effectivenessVSAvoidease of waste removal
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent uses a plunger as an intermediary mechanism to eject waste from the strainer basket. The plunger pushes the accumulated debris out through the drain opening, allowing complete waste removal without requiring users to insert their fingers into the strainer to manually pick out hair and objects, thus improving ease of operation while maintaining reliable filtration

Inventive Principle:
Principle #24Intermediary (Mediator)

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 waste by ejecting it without touching it.

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

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.
