Compact Foldable Stroller Frame for Multiple Seating Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strollers lack a compact folding mechanism that maintains multiple seating modes and suitable wheel assemblies for uneven terrain while minimizing storage space.
Innovation Solution
A collapsible stroller frame with a series of connections, linkages, and assemblies that allow for a compact package, featuring a basket assembly that extends cantilevered from the frame and a foldable seat mount system, along with an adaptor assembly for child carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the stroller is designed to be collapsible for compact storage and transportation, then the storage space and transportation convenience are improved, but the full range of features associated with the child seat or stroller frame may be compromised
Solution Approach 1:
The stroller frame is divided into multiple separable components including front and rear leg portions, handle portion, seat mount, and wheel assemblies that can be independently folded and reconfigured. This segmentation allows each component to be optimized for both compact folding and maintaining full seating configuration capabilities when assembled.
Solution Approach 2:
The stroller employs dynamic folding mechanisms with pivot connections and linkages that allow the frame to transition between extended operational states and compact folded states. The seat mount includes movable components that can be positioned in multiple configurations while maintaining structural integrity during folding operations.
2Volume of moving object
If the stroller frame is folded to a compact size, then the storage efficiency is improved, but the basket assembly space and accessibility may be reduced
Solution Approach 1:
The basket assembly is designed to nest within or alongside other stroller components when folded. The cantilevered basket structure can be positioned to utilize the space created by the folded frame, allowing maximum storage capacity in the compact configuration without interfering with the folding mechanism.
3Adaptability or versatility
If the stroller uses larger wheel assemblies suitable for uneven terrain, then the terrain capability is improved, but the overall size and folding compactness may worsen
Solution Approach 1:
The wheel assemblies are designed as separate, removable components that can be independently folded against the frame or detached entirely. This allows the stroller to maintain large, terrain-capable wheels when assembled while achieving compact folding dimensions when the wheels are positioned vertically or removed from the main frame structure.
