Three-Layer Pet Bowl with Non-Skid Rubber Base

Solution Overview

Problem

Existing pet bowls, particularly molded plastic bowls, are prone to displacement by pet activity due to their light weight, leading to mess and wastage, and existing solutions either fail to provide complete non-displaceability or increase costs significantly.

Innovation Solution

A three-layer pet bowl structure composed of stainless steel, TPE, and plastic, with a non-skid rubber layer permanently attached for enhanced stability and aesthetics, manufactured through injection molding, stamping, and edge rolling processes to ensure durability and cost-effectiveness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If molded plastic bowls are used, then manufacturing cost is low and appearance is colorful, but weight is very light causing easy displacement by pet activity

Engineering Contradiction:

Improvemanufacturing costVSAvoidbowl weight

Core Design Contradiction:

Ease of manufactureVSWeight of moving object

Solution Approach 1:

The invention uses a composite structure combining plastic material for the bowl body with a rubber or silicone non-skid base layer. This composite material approach allows the bowl to maintain the low cost and colorful appearance of plastic while adding the weight and friction properties of rubber/silicone to prevent displacement during pet activity.

Inventive Principle:

Principle #40Composite materials

2Weight of moving object

If thicker and heavier walls are molded to increase weight, then displacement difficulty increases, but manufacturing cost increases significantly

Engineering Contradiction:

Improvebowl weightVSAvoidmanufacturing cost

Core Design Contradiction:

Weight of moving objectVSEase of manufacture

Solution Approach 1:

Instead of making the entire bowl structure thicker and heavier, the invention segments the weight-increasing function into a separate non-skid base layer. This allows the main bowl body to remain lightweight and inexpensive, while only the base portion adds significant weight to prevent displacement, thereby avoiding significant manufacturing cost increases.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention combines plastic material for the bowl body with a rubber or silicone non-skid base layer. This composite material approach allows the bowl to maintain the low cost and colorful appearance of plastic while adding the weight and friction properties of rubber/silicone to prevent displacement during pet activity.

Inventive Principle:

Principle #40Composite materials

3Stability of the object's composition

If inner and/or outer walls are molded to increase weight, then stability improves, but manufacturing cost increases significantly

Engineering Contradiction:

Improvebowl stabilityVSAvoidmanufacturing cost

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

Instead of making the entire bowl structure thicker and heavier, the invention segments the weight-increasing function into a separate non-skid base layer. This allows the main bowl body to remain lightweight and inexpensive, while only the base portion adds significant weight to prevent displacement, thereby avoiding significant manufacturing cost increases.

AI summary

The present invention is related to the pet feeder bowl. The bowl has three layers. Non-skid rubber is permanently attached to the bowl and raised till the top to give additional strength and Hermosa looks, so that the rubber cannot tear off or get damaged in different weather condition. The bowl can directly be put into the dishwasher, as all the materials, i.e. plastic, steel bowls and rubber are permanently attached to each other.
