Stroller with Expandable Wheelbase and Integrated Adapter Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double strollers have a larger footprint than single strollers when used as single occupant configurations, making them difficult to maneuver in confined spaces, and adapters for additional seats can be lost or misplaced during storage and use.
Innovation Solution
A stroller design with a front wheel assembly that can move relative to a rear wheel assembly, allowing for an expandable footprint, and includes a lock/unlock mechanism, telescoping components, and a collapsible frame with a control module for easy deployment and storage, along with a purpose-built storage compartment for adapters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stroller is designed with a fixed large footprint to accommodate double occupancy, then it can support two seats, but it becomes difficult to maneuver in confined spaces when used as a single stroller
Solution Approach 1:
The stroller employs a dynamic footprint adjustment mechanism where the front wheel assembly can move relative to the rear wheel assembly along rails. This allows the stroller to transition between a compact configuration for single occupancy (improving maneuverability) and an expanded configuration for double occupancy (improving adaptability). The lock/unlock mechanism enables the user to switch between these states as needed.
2Adaptability or versatility
If adapters are made detachable for flexibility, then they can be removed and reattached, but they may be lost or misplaced during storage, transportation or use
Solution Approach 1:
The patent integrates the adapters directly into the stroller frame structure, merging them with the permanent components. This eliminates the risk of adapters being lost or misplaced while maintaining the flexibility to attach and detach seats. The adapters become a reliable, fixed part of the stroller system rather than separate removable components.
3Stability of the object's composition
If the stroller frame is rigid and fixed, then it provides structural stability, but it cannot be collapsed for easy storage and transportation
Solution Approach 1:
The stroller frame is segmented into collapsible sections with hinge joints that allow the frame to be folded into a compact configuration for storage and transportation. When assembled, the segments form a rigid structure that provides the necessary structural stability. This segmentation enables the frame to transition between stable and collapsible states as needed.

AI summary
A stroller, includes a front wheel assembly and a rear wheel assembly. The front wheel assembly includes two front wheels respectively disposed at a left and a right side of the stroller. The rear wheel assembly includes two rear wheels respectively disposed at the left and the right side of the stroller. The front and rear wheels define a footprint of the stroller on a walking surface. The front wheel assembly is configured to be movable relative to the rear wheel assembly with one degree of freedom to change the footprint of the stroller.
