Collapsible Stroller with Pivoting Wheel Units for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional juvenile strollers lack a compact storage solution, occupying excessive space in vehicles and storage areas, and often require complex folding mechanisms that are cumbersome for caregivers.
Innovation Solution
A collapsible stroller design featuring a rolling base with pivotable wheel units and a juvenile seat that can be easily converted between an expanded use mode and a compact storage mode, allowing the stroller to be folded into a compact configuration for storage, with additional features like a convertible basket and handle system for versatile use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional stroller designs are used, then the stroller provides adequate seating and mobility functions, but the stroller occupies excessive storage space and is difficult to fold
Solution Approach 1:
The stroller is divided into separate functional modules: a collapsible frame assembly with front and rear wheel units, a seat assembly, and a storage basket. Each module can be independently folded or collapsed, allowing the entire stroller to be disassembled into compact segments for storage while maintaining ease of operation through modular design
Solution Approach 2:
The front wheel unit is designed to nest within the rear wheel unit when both are in their collapsed positions. The storage basket collapses to fit within the frame assembly, and the entire stroller can be configured to nest within itself, maximizing space efficiency without requiring complex folding mechanisms
2Volume of moving object
If the stroller is designed with a compact storage configuration, then storage space is reduced, but the stroller may become unstable or difficult to maneuver
Solution Approach 1:
The wheel units are designed with dynamic positioning capability, allowing them to pivot between extended and retracted positions. When in use, the wheels extend outward to provide a stable base and proper ground clearance. When collapsed for storage, the wheels pivot inward to reduce volume. This dynamic adjustment maintains stability during operation while achieving compactness during storage
Solution Approach 2:
The front and rear wheel units are positioned asymmetrically on the frame, with the front wheel unit capable of pivoting to a nested position within the rear wheel unit. This asymmetric arrangement allows for optimized stability during use while enabling compact nesting during storage, as the wheels are positioned to create a stable triangular base when extended but can be collapsed to a compact linear configuration
