Rotatable Base Mechanism for Compact Baby Stroller Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baby strollers cannot be folded completely when the seat is in a rearward facing position due to interference with the stroller frame, requiring the seat to be removed for folding, which complicates storage and transportation.
Innovation Solution
A baby stroller design featuring a rotatable base that connects the seat to the stroller frame, allowing the seat to rotate during folding and maintain a compact position, eliminating interference and enabling easy folding in both forward and rearward facing configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the seat is in a rearward facing position, then the seat can face the parent/guardian, but the seat interferes with the stroller frame during folding process
Solution Approach 1:
The base is made rotatable relative to the stroller frame, allowing it to change orientation dynamically. When the stroller is folded, the base rotates to align with the frame, enabling the seat to be in a rearward facing position without interfering with the folding process. This dynamic adjustment resolves the contradiction between seat orientation adaptability and folding ease.
2Adaptability or versatility
If the seat protrudes from the stroller frame, then the seat can accommodate the child, but the folded stroller size increases and takes up more storage space
Solution Approach 1:
The base rotates during the folding process to align with the stroller frame, allowing the seat to fold compactly along with the frame. This dynamic rotation enables the seat to maintain its child-accommodating structure while reducing the overall folded volume to a compact size suitable for storage and transportation.
3Volume of moving object
If the seat is removed before folding, then the stroller can be folded completely, but the operation becomes complicated and parts may be lost
Solution Approach 1:
The rotatable base allows the seat to remain attached to the stroller frame while automatically adjusting its position during folding. This eliminates the need to remove the seat before folding, simplifying the operation to a single folding action while still achieving complete compaction. The base rotates to align with the frame, preventing interference and enabling the seat to fold completely with the stroller.

AI summary
A baby stroller is formed by a stroller frame and a chair, and the stroller frame includes a rotatabie base,, such that when the baby stroller is unfolded, the base is provided for abutting the stroller frame and positioned automatically, and. when the baby stroller is folded, the chair and the stroiler irame are folded and positioned directly together with the rotation of the base, and the chair includes a. folding joint, such, that the chair can be folded directly onto the stroller frame to provide a simple, easy and quick operation and achieve the effect of reducing the storage volume of the baby stroller.
