Solution Overview

Problem

Pet owners need a solution that allows them to engage in activities with their pets without the need for multiple backpacks, as existing solutions do not efficiently convert between pet-carrying and backpacking functions.

Innovation Solution

A convertible backpack that can transition between a pet-carrying and backpacking mode, featuring a clip-on bag that covers the open top and paw holes to protect contents and secure items, along with waist straps for ergonomic carrying.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a pet-carrying backpack is designed with an open top and paw holes to allow pet access, then the pet can easily enter and exit the backpack, but the backpack cannot be used for carrying gear without the pet

Engineering Contradiction:
Improvepet accessVSAvoidbackpack usage
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The backpack incorporates a convertible top structure that can dynamically change between open and closed states. The top includes a first portion that remains fixed and a second portion that can be raised or lowered, allowing the backpack to transition between pet-accessible mode and gear-carrying mode. This dynamic structure enables the same backpack to serve multiple functions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The backpack is designed with universal functionality to serve both as a pet-carrying backpack and a gear-carrying backpack. The convertible top, combined with adjustable shoulder straps and an accessory bag system, allows the single backpack to adapt to different use cases, eliminating the need for separate backpacks for different purposes.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Quantity of substance

If a pet-carrying backpack uses an accessory bag attached to the back for additional storage, then storage capacity is increased, but the accessory bag must be detached and reattached during conversion

Engineering Contradiction:
Improvestorage capacityVSAvoidconversion process
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The accessory bag is designed as a separate, detachable component that can be easily removed from the backpack body. During conversion from pet-carrying mode to gear-carrying mode, the accessory bag is detached from its original position on the back of the backpack and can be repositioned or removed entirely, simplifying the conversion process while preserving storage capacity when needed.

Inventive Principle:
Principle #2Taking out (Extraction)

3Device complexity

If the open top and paw holes are left uncovered when not carrying a pet, then the backpack structure remains simple, but water and debris can enter the internal compartments

Engineering Contradiction:
Improvebackpack structureVSAvoidwater intrusion
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The convertible top structure allows the second portion of the top to be lowered over the open top and paw holes when the backpack is not being used to carry a pet. This dynamic closure prevents water and debris from entering the internal compartments while maintaining a relatively simple backpack structure that doesn't require separate covers or flaps.

Inventive Principle:
Principle #15Dynamics

AI summary

A convertible pet-carrying and backpacking backpack that comprises a backpack body defining one or more internal compartments and an open top operable to allow the head of a pet to extend therethrough. The backpack body further comprises shoulder straps extending from the front of the backpack body, and paw holes disposed on the front of the backpack body above the shoulder straps. The paw holes are operable to allow paws of the pet to extend therethrough. The backpack can further comprise an accessory bag operable to selectively attach to and detach from the backpack body at a first position where the accessory bag extends from the back of the backpack body so that the backpack is in a pet-carrying configuration, and a second position where the accessory bag covers the open top of the backpack body so that the backpack is in a backpacking configuration.
