Solution Overview

Problem

Existing pet relief stations using artificial turf often retain odors and fail to contain pet waste effectively, leading to unpleasant experiences for humans and maintenance challenges.

Innovation Solution

A portable pet station system featuring a base with perimeter walls, removable splash guard walls, and a grass mat that can be maintained with a sprayer and replaced regularly, along with adjustable splash guard walls and a design to direct urine centrally for easier cleaning and odor mitigation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-generated harmful factors

If artificial turf is used as a base to collect pet waste, then pet waste can be contained, but odors are retained creating an unpleasant experience for humans

Engineering Contradiction:
Improveodor retentionVSAvoidwaste containment
Core Design Contradiction:
Object-generated harmful factorsVSEase of operation

Solution Approach 1:

The patent employs disposable artificial turf liners that are placed on the base and removed after use. These liners are designed to be discarded after collecting pet waste, preventing odor retention in the permanent structure while maintaining effective waste containment during the usage period. The liner acts as a temporary, replaceable barrier that solves the contradiction between containment effectiveness and odor prevention.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Object-generated harmful factors

If flat trays containing artificial turf are used, then pet waste can be collected, but there is no way to avoid pet waste from extending beyond the confines of the tray

Engineering Contradiction:
Improvewaste containmentVSAvoidwaste spillage prevention
Core Design Contradiction:
Object-generated harmful factorsVSShape

Solution Approach 1:

The patent incorporates flexible, adjustable splash guard walls that can be raised or lowered based on the pet's size and the specific situation. These dynamic barriers adapt to different needs, providing effective containment for larger pets or messy situations while remaining unobtrusive when not needed. The ability to adjust the barrier height dynamically resolves the contradiction between maintaining an open design and preventing waste spillage.

Inventive Principle:
Principle #15Dynamics

3Object-generated harmful factors

If fixed height splash guard walls are used, then waste containment is improved, but the system cannot accommodate various pets and environments

Engineering Contradiction:
Improvewaste containmentVSAvoidpet size accommodation
Core Design Contradiction:
Object-generated harmful factorsVSAdaptability or versatility

Solution Approach 1:

The splash guard walls are designed to be adjustable in height, allowing the system to adapt to different pet sizes, genders, and environmental conditions. Users can raise the walls for larger or more active pets that may splash or dig, and lower them for smaller or more restrained pets. This dynamic adjustability maintains effective waste containment while providing versatility across different usage scenarios.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The splash guard system is divided into separate, adjustable segments rather than a fixed monolithic structure. Each section can be independently adjusted or removed, allowing customization for different pet sizes and tray configurations. This segmentation enables the same system to effectively serve multiple pet types and situations without requiring different complete systems.

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The system effectively contains and absorbs pet waste, reduces odor retention, and requires minimal maintenance by using real grass that absorbs liquids and odors, with adjustable features to accommodate various pets and environments.

Implementation Method 1

real grass that absorbs liquids and odors

Methodology Applied
Scientific EffectAbsorption: Absorption (physical)

Implementation Method 2

real grass that absorbs liquids and odors

Methodology Applied
Scientific EffectAdsorption: Adsorption

Implementation Method 3

a sprayer, where the sprayer may be configured to maintain moisture in the grass mat

Methodology Applied
Scientific EffectSpray: Spray

Implementation Method 4

the one or more perimeter walls comprise a curved section sloping down to the base, where the curved section provides for easier cleaning and directs urine on the one or more removable splash guard walls toward a middle of the tray and away from edges of the tray

Methodology Applied
Scientific EffectGravity: Gravitation
