Solution Overview

Problem

Pet owners face challenges in participating in activities with their pets, especially those with size or health issues, as existing solutions do not provide a convenient and comfortable way to transport pets during travel or outdoor activities without leaving them in care facilities.

Innovation Solution

A pet-carrying backpack with a bottom-entry opening, back-support opening, paw holes, and adjustable straps, allowing easy loading and secure carrying of pets, along with optional accessories for comfort and support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional top-entry backpack is used to carry pets, then the pet is securely enclosed, but it becomes difficult for the pet to enter and exit the backpack comfortably

Engineering Contradiction:

Improveease of pet loadingVSAvoidbackpack structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The backpack is divided into multiple access points: a bottom-entry opening with a detachable bottom portion and a rear back-support opening. This segmentation allows pets to enter through the bottom while owners can access the rear for support and control, resolving the contradiction by providing multiple functional openings without requiring complete structural redesign.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of the traditional top-entry design where pets must be lifted overhead, this invention inverts the entry point to the bottom of the backpack. The bottom portion is made detachable via zipper, allowing pets to walk in naturally from the ground level, making loading much easier while maintaining secure enclosure when zipped closed.

Inventive Principle:

Principle #13The other way round (Inversion)

2Adaptability or versatility

If the backpack is designed to accommodate pets of various sizes, then versatility is improved, but the fit and security for individual pets may be compromised

Engineering Contradiction:

Improvepet size accommodationVSAvoidpet security

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The backpack incorporates adjustable and detachable components including the bottom portion, back-support opening, and internal straps. These dynamic elements can be adjusted or reconfigured based on the specific pet's size and needs, allowing the same backpack to securely accommodate different pet sizes while maintaining reliable enclosure through proper adjustment of the adjustable features.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If a bottom-entry opening is added to allow easy pet loading, then ease of operation is improved, but the structural integrity and security of the backpack may be compromised

Engineering Contradiction:

Improvepet loading convenienceVSAvoidbackpack structural integrity

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The bottom portion of the backpack is extracted as a detachable component separated from the main body via zipper. This allows the bottom to be removed for easy pet loading while maintaining the structural integrity of the main backpack body when the bottom is attached and zipped closed, resolving the contradiction between ease of loading and structural strength.

Inventive Principle:

Principle #2Taking out (Extraction)
