Pet Stroller Canopy Bar Latch for Sidewall Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable pet strollers lack a defined sidewall for the platform seating area when the canopy is open, leading to insecurity and potential escape risks for pets, as the mesh remains unsupported and floppy, necessitating the canopy to be kept closed for safe use.
Innovation Solution
A pet stroller design featuring a platform enclosure member that pivots to form a parallel sidewall around the seating area, combined with an over-center latch assembly that clamps the canopy bar to the platform enclosure member, creating a secure and enclosed space, and a base board with a clip for additional stability, allowing for compact folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the canopy is opened in existing pet strollers, then the pet seating area lacks a defined sidewall and the mesh becomes unsupported and floppy, but keeping the canopy closed restricts ventilation and visibility
Solution Approach 1:
The invention divides the canopy structure into separate functional components: the canopy assembly that provides coverage and the platform enclosure member that provides sidewall support. This segmentation allows the canopy to be opened for ventilation while the enclosure member independently maintains pet containment security through the latchable canopy bar mechanism.
2Reliability
If a latchable canopy bar mechanism is added to secure the canopy when open, then pet containment security is improved, but the device complexity increases
Solution Approach 1:
The latch assembly is designed to be self-latching through the over-center mechanism, which automatically secures the canopy bar to the platform enclosure member when engaged. The spring-loaded button releases the latch, eliminating the need for separate locking operations and reducing operational complexity despite the added structural components.
3Reliability
If the platform enclosure member is made pivotable to form a parallel sidewall, then pet safety is enhanced with a defined seating area, but the manufacturing precision requirements increase
Solution Approach 1:
The platform enclosure member is designed with pivotable connections at its ends, allowing it to dynamically adjust and form a parallel sidewall relative to the platform base. This dynamic configuration provides a defined seating area for pet safety while accommodating manufacturing tolerances through the pivot mechanism's inherent flexibility.
