Solution Overview

Problem

Existing drain line adapters face clogging issues due to large solids from kitchen sink waste and loose connections with water filtration systems, which are often mitigated by expensive internal baffles or removable couplings.

Innovation Solution

The drain line adapter features a primary conduit and a branch conduit oriented at an angle greater than ninety degrees, combined with a slip joint connector and a push connector, to prevent clogging and secure connections without internal baffles or removable couplings, ensuring efficient waste flow and secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an internal baffle is used to prevent clogging, then clogging is hindered, but manufacturing cost increases and waste flow is obstructed

Engineering Contradiction:
Improveclogging preventionVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The invention removes the internal baffle component entirely and replaces it with a geometric configuration of the conduits themselves. The branch conduit is positioned at an angle greater than ninety degrees relative to the primary conduit, creating a self-directed flow path that prevents solid accumulation without requiring additional manufacturing steps or components.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the geometric parameter of the conduit arrangement by positioning the branch conduit at an angle greater than ninety degrees. This angular parameter change fundamentally alters the flow dynamics, using gravity and flow direction to prevent solid waste from settling in the branch conduit, thereby achieving clogging prevention through geometry rather than additional components.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If a removable coupling is used to connect water filtration system, then installation is easier, but connection security deteriorates over time

Engineering Contradiction:
Improveinstallation easeVSAvoidconnection security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The invention merges the connection functionality directly into the conduit structure by integrating a push connector as an inherent part of the branch conduit. This eliminates the need for separate removable couplings while maintaining installation simplicity. The push connector provides a permanent, secure connection that prevents loosening over time while preserving ease of initial installation.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If the branch conduit is positioned horizontally, then connection is simplified, but solid waste accumulation increases

Engineering Contradiction:
Improveconnection simplicityVSAvoidclogging resistance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The invention changes the angular parameter of the branch conduit positioning to greater than ninety degrees relative to the primary conduit. This geometric parameter change creates a self-draining configuration where gravity and flow direction work together to prevent solid waste accumulation, maintaining clogging resistance while preserving connection simplicity.

Inventive Principle:
Principle #35Parameter changes
