Solution Overview

Problem

Existing pet carts have an integrated design, which occupies large spaces during carry, and are not convenient and occupy, and the closure is slow, the pet may jump out to cause danger, and meanwhile, the space in the bag is low, movement of the pet is limited during walking, and the above-mentioned technologies are complicated during folding, disassembly, unfolding, and assembly, and are not convenient.

Innovation Solution

A retractable, detachable and portable pet stroller with a handle, the stroller body is detachably connected to the stroller basket, a first locking mechanism is provided at the bottom of the stroller basket, the folding roof is detachably connected to the stroller basket, and a third locking mechanism is further provided at the top of the stroller basket, allowing for easy disassembly and folding, reducing storage space, and enabling flexible use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the pet cart uses an integrative design, then the structure is simple, but it occupies large spaces during carry and is not convenient

Engineering Contradiction:
Improvestructure simplicityVSAvoidstorage space
Core Design Contradiction:
Device complexityVSVolume of moving object

Solution Approach 1:

The pet cart is divided into separable components: the stroller basket can be detached from the stroller body, and the folding roof can be removed independently. This segmentation allows each component to be stored separately, significantly reducing the storage space required while maintaining structural simplicity when assembled.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If the bag body is closed by zippers, then the structure is simple, but the closure is slow and the pet may jump out causing danger

Engineering Contradiction:
Improveclosure structureVSAvoidclosure time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The closure mechanism transitions from a static zipper system to a dynamic snap-fit system with locking buttons. The snap-fit design allows for rapid engagement and disengagement, significantly reducing closure time while preventing the pet from jumping out through the securely locked basket.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the folding mechanism is complex, then the folding function is achieved, but it is complicated during folding, disassembly, unfolding and assembly

Engineering Contradiction:
Improvefolding capabilityVSAvoidoperational convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The folding mechanism is segmented into independent sections with standardized connection interfaces. Each section can be folded or detached separately using simple locking buttons, eliminating the need for complex coordinated operations and making the folding and assembly process straightforward.

Inventive Principle:
Principle #1Segmentation

4Volume of moving object

If the stroller basket is detachable, then the storage space is reduced, but the assembly and disassembly process becomes more complex

Engineering Contradiction:
Improvestorage spaceVSAvoidassembly complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The detachable connection system uses dynamic snap-fit joints with locking buttons instead of static permanent connections. This allows the stroller basket to be quickly attached and detached from the stroller body through simple button operations, reducing assembly complexity despite the detachable design.

Inventive Principle:
Principle #15Dynamics

AI summary

A retractable, detachable and portable pet stroller is disclosed, including a stroller body, a stroller basket and a folding roof. The stroller body is detachably connected with the stroller basket, and a locking mechanism for fixation is provided at a bottom of the stroller basket. The folding roof is detachably connected with the stroller basket, and a second locking mechanism for fixation is provided on the folding roof. A third locking mechanism for fixing a movable end of the folding roof is further provided at a top of the stroller basket. Because the stroller basket can be disassembled and folded, and the roof can also be disassembled and folded, the stroller basket can be used independently, offering flexibility and convenience when a user goes out with a pet.
