Rotatable Base Stroller Frame Folding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baby strollers have a large folding volume due to protruding seats, making them inconvenient to transport and store, and require complex procedures to fold without losing parts, especially when the seat is facing backward.
Innovation Solution
A baby stroller design featuring a rotatable base that automatically positions a seat latch when unfolded and includes a folding joint, allowing the chair to rotate and fold directly with the stroller frame, simplifying the folding process and reducing storage volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the seat protrudes from the stroller frame, then the seat can be mounted and dismounted independently, but the folding volume becomes too large making transportation inconvenient
Solution Approach 1:
The seat is designed to be nested within the stroller frame during folding. The seat back and seat base are positioned inside the frame structure, allowing the entire assembly to fold into a compact configuration without the seat protruding outward, thus reducing folding volume while maintaining independent mounting capability
2Adaptability or versatility
If the seat faces backward, then the seat can accommodate different positioning needs, but the seat interferes with the stroller frame during folding making direct folding impossible
Solution Approach 1:
The seat is designed with dynamic positioning capability that allows it to rotate and adjust its orientation. When folding is required, the seat can be rotated to a forward-facing position or a neutral position that clears the frame, enabling direct folding without removal. This dynamic adjustment resolves the interference issue while maintaining backward-facing capability when needed
3Ease of operation
If the seat is removed before folding, then the stroller frame can be folded directly, but the operation becomes complicated and parts may be lost
Solution Approach 1:
The seat mounting mechanism is integrated with the frame folding mechanism through the rotatable base and latch system. The seat remains attached to the frame during folding, and the folding action itself becomes part of the seat retention system. This merging eliminates the separate removal step, simplifying the procedure to a single integrated action while ensuring parts remain connected

AI summary
A baby stroller is formed by a stroller frame and a chair, and the stroller frame includes a rotatable base. 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 stroller frame are folded and positioned directly together with the rotation of the base. 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 to achieve the effect of reducing the storage volume of the baby stroller.
