Solution Overview

Problem

Existing drainpipe filters are ineffective in preventing solid debris, such as hair, from clogging, and they are difficult to install and clean.

Innovation Solution

A removable pipe filter device comprising a first pipe connected to a drainpipe with a second pipe and a releasable filter that extends into the conduit, inhibiting debris from exiting through the other end and allowing easy removal of collected debris.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a mesh cover is used at the inlet of the drainpipe to capture hair, then the amount of solid debris entering the drainpipe is reduced, but the device becomes difficult to remove for cleaning and proper disposal

Engineering Contradiction:
Improvedebris blocking effectivenessVSAvoidfilter removal and cleaning ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The filter device is divided into separate components: a first pipe section that connects to the drainpipe and a second pipe section containing the filter. This segmentation allows the filter to be easily removed from the second pipe for cleaning and disposal while the first pipe remains installed, resolving the contradiction between effective debris blocking and ease of filter maintenance.

Inventive Principle:
Principle #1Segmentation

2Reliability

If a fixed filter device is installed in the drainpipe, then debris can be trapped effectively, but the device complexity increases and installation becomes more difficult

Engineering Contradiction:
Improvedebris trapping effectivenessVSAvoidinstallation and structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The drainpipe is segmented into a first pipe portion and a second pipe portion, with the filter integrated into the second pipe. This segmentation simplifies installation by allowing the filter assembly to be attached as a separate unit to the existing drainpipe, rather than requiring complex integration into the entire pipe system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second pipe acts as an intermediary component between the drainpipe and the filter. It provides a simple connection interface that facilitates easy installation and removal of the filter without requiring complex modifications to the existing drainpipe system.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the filter extends deeply into the conduit to maximize debris capture, then debris trapping effectiveness improves, but the filter becomes more difficult to remove and clean

Engineering Contradiction:
Improvedebris capture effectivenessVSAvoidfilter accessibility for cleaning
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The filter is contained within the second pipe section, which can be easily detached from the first pipe section. This segmentation allows the filter to extend into the conduit for effective debris capture while maintaining easy accessibility for removal and cleaning by simply detaching the second pipe section.

Inventive Principle:
Principle #1Segmentation

AI summary

A removable pipe filter device for blocking and removing debris from traveling through piping includes a first pipe having a pair of open ends being configured for connection to a drainpipe. The first pipe defines a conduit between the pair of open ends. A second pipe is coupled to the first pipe. The second pipe is in environmental communication with the conduit between the pair of open ends of the first pipe. The second pipe has a distal edge relative to the first pipe defining an opening into the second pipe. A filter is releasably couplable to the second pipe. The filter extends into the second pipe. The filter inhibits solid debris entering the conduit through a first end of the pair of open ends from exiting the conduit through a second end of the pair of open ends when the filter is coupled to the second pipe.
