Convertible Child Carrier with Pivotable Hub and Nested Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child strollers are bulky and cumbersome when transitioning between collapsed and deployed states, and their collapsed form often occupies significant space, making storage and transport difficult, while also rendering previous storage areas unusable.
Innovation Solution
A deployable child carrier with pivotable central hub members, a yoke member, and rear legs, which can be collapsed into a stowed configuration within a storage compartment, allowing the device to function as a mobile storage unit with integrated stroller mechanism and internal compartments for user items, featuring a handle member and carry straps for easy transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the stroller is made collapsible to improve storageability, then storage space is reduced, but the structure becomes bulky and cumbersome during transition
Solution Approach 1:
The stroller frame is divided into multiple telescopic segments (front wheel assembly, rear wheel assemblies, yoke member) that can independently collapse. Each segment contains nested tubes that allow compact folding while maintaining structural integrity, enabling the entire frame to reduce volume without creating bulky transition states.
Solution Approach 2:
The telescopic mechanism allows one segment to nest within another during collapse. The front wheel assembly nests within the yoke member, and rear wheel assemblies nest within the frame members, creating a compact nested configuration that minimizes storage volume while allowing smooth transition through controlled segment collapse.
2Volume of moving object
If the stroller is collapsed to improve storageability, then storage space is reduced, but the collapsed state occupies significant space and presents transport difficulties
Solution Approach 1:
The stroller employs dynamic telescopic mechanisms that allow continuous adjustment of segment lengths. The front wheel assembly, rear wheel assemblies, and yoke member can be independently extended or retracted, enabling the structure to adapt its configuration for optimal transportability while maintaining a compact collapsed state.
Solution Approach 2:
The collapsed stroller configuration serves multiple functions: it can be stored in limited spaces, transported in vehicles, and easily deployed when needed. The same telescopic mechanism that enables compact storage also facilitates easy deployment, making the device universally applicable for both storage and transport scenarios.
3Volume of moving object
If the stroller is collapsed to improve storageability, then storage space is reduced, but previously available storage areas become unusable
Solution Approach 1:
The stroller collapse mechanism utilizes multi-dimensional folding to reduce volume. By telescoping segments in multiple directions and creating nested configurations, the stroller transforms from a three-dimensional structure to a compact form that can be stored in previously unavailable spaces, effectively adding storage capacity through dimensional transformation.

AI summary
A convertible child carrier is provided comprising a pair of opposing central hub members having telescopic rear legs pivotally attached the hub members at a first end. Each of the legs has a pivotable wheel affixed to a second end. The child carrier further includes a yoke member generally defining an arch-like shape that is also pivotally attached to both of the pair of hub members. An additional wheel is affixed a central section of the yoke member. The child carrier further includes a handle member pivotally attached to each of the hub members, a seating portion disposed between the distal ends of the yoke member, and a storage portion affixed to the handle member defining an internal storage cavity. The rear legs, the yoke member, and the handle member each may pivot to a stowed configuration such that the storage portion encompasses the members within the storage cavity.
