Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing pet bed platforms fail to effectively control pet hair and dander spread, as they either create positive air pressure that disperses debris or lack air filtration systems that can contain hair and dander while the animal is present.

Innovation Solution

A pet bed platform with an air filtration and control system that maintains a negative air pressure around the bed tray, using a blower unit, air duct, and air suction gap to draw air and debris into an air filtration system, while allowing airflow from multiple sides to cool the animal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If fans are used to blow air into the housing or pet bed for cooling, then the pet cooling effect is improved, but positive air pressure is created that causes pet hair, dander and other debris to be tossed into the air and spread throughout the home

Engineering Contradiction:

Improvepet coolingVSAvoidpet hair and dander spread

Core Design Contradiction:

TemperatureVSObject-generated harmful factors

Solution Approach 1:

The patent inverts the conventional approach by using negative air pressure instead of positive air pressure. The air filtration system creates negative pressure within the housing, which draws air in through controlled intake openings rather than forcing air out through fans. This reversal of pressure differential achieves both cooling and containment of pet hair and dander simultaneously.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent introduces air intake openings as intermediary elements that control airflow into the housing. These openings are positioned and designed to allow fresh air to enter for cooling purposes while the negative pressure system prevents hair and dander from escaping through the same openings, effectively mediating between cooling requirements and containment needs.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-generated harmful factors

If air filtration systems are used in closed box type housings, then pet hair and dander are contained, but the animal is scared away by fan noise when the animal is not present

Engineering Contradiction:

Improvepet hair and dander containmentVSAvoidanimal comfort and presence

Core Design Contradiction:

Object-generated harmful factorsVSEase of operation

Solution Approach 1:

The patent enables the housing to self-regulate airflow and maintain negative pressure without requiring active fan operation. The passive air intake openings and negative pressure design allow the system to function automatically based on pressure differentials, eliminating the need for noisy fans that would scare animals away, while still maintaining effective hair and dander containment.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If open pet bedding surfaces are used, then the animal has freedom of movement and comfort, but they do nothing to control the flow of air around the pet or actively work to control pet hair, dander and debris

Engineering Contradiction:

Improveanimal comfort and freedomVSAvoidpet hair, dander and debris control

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent employs the housing structure as a flexible boundary that guides airflow patterns. The air intake openings and housing design create controlled flow paths that move air across the pet's body for cooling while directing hair and dander toward filtration areas, combining animal comfort with effective debris control.

Inventive Principle:

Principle #30Flexible shells and thin films

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 pet hair and dander within the pet bed platform, preventing their dispersal throughout the home, while providing a comfortable cooling airflow for the animal and reducing the need for frequent vacuuming.

Implementation Method 1

maintain a negative air pressure around the bed tray to draw air from around the animal and the bed tray into an air filtration system

Methodology Applied

Scientific EffectNegative air pressure: Pressure Gradient

Implementation Method 2

draw air from around the animal and the bed tray into an air filtration system to resist pet hair, dander and other debris from exiting the pet bed platform

Methodology Applied

Scientific EffectFiltration: Filter (physical)

AI summary

A base platform carrying a bedding tray with a plurality of tray legs raising the bedding tray above the base platform to define an air channel between the base platform and the bedding tray. An air suction gap between a perimeter wall surrounding the bedding tray and a perimeter side surface of the bedding tray, wherein the air suction gap extends around an entire perimeter of the bedding tray. Airflow openings included in the bedding tray drawing air through the bedding tray downward into the air channel. A blower unit carried by the base platform drawing air downward through the bedding tray and the air suction gap into the air channel, wherein the air suction gap channels air downward from around the entire perimeter of the bedding tray and into the air channel underneath the bedding tray so that debris is drawn down around the sides of the bedding tray.
