Solution Overview

Problem

Conventional garbage disposal systems lack an effective mechanism to prevent larger objects and liquids from entering the drain while allowing particulate matter to be shredded and disposed of, leading to clogging and inefficiencies.

Innovation Solution

A garbage disposal stopper/strainer system comprising a cap, top, insert, base, and scraper, where the insert and base holes align to allow liquid passage while preventing larger objects, and can be rotated to stop liquid flow by misaligning the holes, along with a cap that secures components and directs liquid flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a conventional garbage disposal system is used, then particulate matter can be shredded and disposed of, but larger objects and liquids can enter the drain causing clogging

Engineering Contradiction:
ImprovecloggingVSAvoidsystem complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The device is segmented into multiple functional components: a strainer portion with holes for filtering larger objects, a stopper portion with alignable holes for controlling liquid flow, and a garbage disposal unit. This segmentation allows each component to perform its specific function while working together to prevent clogging without requiring a completely complex system redesign.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The stopper/strainer assembly serves multiple functions simultaneously: it acts as a strainer to prevent larger objects from entering the drain, a stopper to control liquid flow by aligning or misaligning holes, and an integrated part of the garbage disposal system. This multi-functionality reduces the need for separate devices while comprehensively addressing clogging prevention.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Object-affected harmful factors

If the stopper/strainer assembly is used to prevent larger objects from entering the drain, then clogging is reduced, but the device complexity increases

Engineering Contradiction:
Improveclogging preventionVSAvoidassembly complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The strainer and stopper functions are merged into a single integrated assembly that attaches to the garbage disposal unit. The strainer portion and stopper portion are combined with alignable holes, allowing the device to perform both filtration and flow control functions through one assembly rather than requiring separate components, thereby reducing overall system complexity while maintaining comprehensive clogging prevention.

Inventive Principle:
Principle #5Merging (Combining)
