Solution Overview

Problem

Conventional pet bowl systems often result in pets overturning their bowls or being tethered too far away, leading to discomfort and safety hazards.

Innovation Solution

A pet bowl system featuring a rigid, tapered bowl design with an elongated central opening for a stake insertion, combined with a stake that can be adjusted in height and rotated, ensuring the bowl remains upright and securely positioned near the pet.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a pet is tethered to a stake, then the pet is prevented from becoming lost, but the pet may be tethered too far from the bowl causing discomfort and safety hazards

Engineering Contradiction:

Improvepet containmentVSAvoidpet comfort and safety

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent combines the tethering stake with the bowl by inserting the stake through a central opening in the bowl, merging two separate functions (tethering and feeding) into a single integrated structure. This ensures the pet remains within a limited radius of the bowl while eating, solving the contradiction between containment reliability and pet comfort.

Inventive Principle:

Principle #5Merging (Combining)

2Ease of operation

If a conventional bowl is used, then the pet can access food and water, but the bowl can be overturned by the pet

Engineering Contradiction:

Improvepet access to food and waterVSAvoidbowl stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The stake passing through the bowl merges the stabilization function with the feeding function, preventing the bowl from being overturned while maintaining pet access to food and water.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The stake is inserted through the bowl before use, preliminarily securing the bowl in an upright position. This preliminary stabilization action prevents the bowl from being overturned during subsequent use by the pet.

Inventive Principle:

Principle #10Preliminary action

3Stability of the object's composition

If the stake is fixed in position, then the bowl remains securely positioned, but the pet's movement freedom is restricted

Engineering Contradiction:

Improvebowl position stabilityVSAvoidpet movement freedom

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent employs a telescoping stake mechanism that can extend and retract, providing dynamic adjustment of the tether length. This allows the bowl to remain securely positioned when needed while granting the pet increased movement freedom when the stake is extended, resolving the contradiction between stability and adaptability.

Inventive Principle:

Principle #15Dynamics
