Solution Overview

Problem

Typical disposal splash guards direct water through a central opening, leading to food waste accumulation in the disposal, necessitating a mechanism to reduce this accumulation.

Innovation Solution

A disposal splash guard design featuring a cylindrical body with a baffle that includes peripheral openings, splits, and flaps, allowing water to flow through these openings instead of the central opening, thereby reducing food waste accumulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If water is directed through the central opening in the disposal splash guard, then the splash guard structure is simple, but food waste accumulates in the disposal

Engineering Contradiction:
Improvesplash guard structureVSAvoidfood waste accumulation
Core Design Contradiction:
Device complexityVSLoss of substance

Solution Approach 1:

The baffle is segmented with multiple peripheral openings distributed around its circumference, dividing the single water flow path into multiple paths. This segmentation allows water to exit at different locations, preventing food waste accumulation while maintaining structural simplicity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from a single central opening (one-dimensional flow path) to multiple peripheral openings distributed around the baffle circumference (multi-dimensional flow paths). This dimensional change enables water to flow through different locations, effectively reducing food waste accumulation

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Loss of substance

If peripheral openings are added to the baffle, then food waste accumulation is reduced, but the baffle structure becomes more complex

Engineering Contradiction:
Improvefood waste accumulationVSAvoidbaffle structure
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The baffle is segmented with multiple peripheral openings distributed around its circumference, dividing the single water flow path into multiple paths. This segmentation allows water to exit at different locations, preventing food waste accumulation while maintaining structural simplicity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The peripheral openings serve multiple functions: they divert water flow to prevent food waste accumulation, and their distributed arrangement helps distribute mechanical loads on the baffle, providing structural benefits in addition to their primary flow diversion function

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