Low-Profile Pet Stroller with Foldable Canopy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet strollers are limited in size and require lifting pets into the stroller, making it difficult to accommodate larger pets and necessitate the use of leashes or enclosures for confinement.
Innovation Solution
A foldable pet stroller design with a lower platform height, allowing pets to step in, and a canopy system that can be opened for easy entry, eliminating the need to lift pets and accommodating larger sizes without the need for leashes or enclosures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the platform height is reduced to allow pets to step in, then ease of operation is improved, but the structural stability may be compromised
Solution Approach 1:
The stroller structure is divided into modular components including the platform, frame members, and support struts that can be independently positioned and locked. This segmentation allows the platform to be positioned at a lower height for easy pet entry while the distributed support structure maintains overall stability through multiple locking points and balanced weight distribution.
Solution Approach 2:
The stroller incorporates dynamic elements such as pivotable struts with latch mechanisms that allow the structure to adapt between different operational states. The struts can be positioned at various angles and locked into place, enabling the platform to maintain optimal height for stability while still allowing low entry points when needed.
2Adaptability or versatility
If the stroller is designed to accommodate larger pets, then adaptability is improved, but the device complexity increases
Solution Approach 1:
The stroller design incorporates universal features such as an adjustable platform height, extendable struts with multiple locking positions, and a scalable canopy system that can accommodate pets of various sizes. These multi-functional elements allow a single stroller model to serve multiple pet size categories without requiring separate designs for each size class.
Solution Approach 2:
The stroller utilizes adjustable parameters including platform height, strut length, and canopy dimensions that can be modified to accommodate different pet sizes. The latch mechanisms and pivot points allow users to adjust these parameters within specific ranges, providing versatility while maintaining a relatively simple base structure that doesn't require complete redesign for different pet sizes.
3Ease of operation
If the canopy is made openable for easy entry, then ease of operation is improved, but the confinement effectiveness may be reduced
Solution Approach 1:
The canopy system is designed with preliminary opening mechanisms that allow the canopy to be easily accessed and opened for pet entry, then automatically returns to or can be quickly returned to its enclosing position. The latch mechanisms and pivot points are positioned to facilitate this preliminary opening action while ensuring the canopy can be securely closed and latched to maintain confinement effectiveness.

AI summary
A pet stroller is provided having a frame assembly which includes a base frame and a back frame. A handle is connected to the back frame. A platform is located on the base frame to define a pet seating area. Two rear wheels and at least one front wheel are connected to the base frame. Two foldable struts are provided, between the base and back frames that are lockable in an extended position and releasable to allow folding of the struts. A back door is connected by hinges to the back frame and has a releasable door latch. A canopy is provided including a cloth canopy assembly and the upper and lower canopy bars. A canopy latch releasably connects the lower canopy bar to a front cross member of the base frame to form an enclosed pet seating area. The platform forming the pet seating area is below a level defined by a top of the rear wheels, and preferably less than 12 inches above ground level, accommodating larger pets and eliminating the need to lift the pet into the pet seating area.
