Stroller Folding Joint With Auto-Rotating Connecting Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional strollers face issues with connecting assemblies, such as armrests and food trays, that do not fold with the stroller frame, resulting in a less compact design after folding or requiring separate disassembly for storage.
Innovation Solution
A folding device with a pivot joint mechanism, rotating base, and locking assembly that allows the connecting assembly to rotate unidirectionally during folding, facilitated by a driving member and locking assembly that switches between locked and unlocked positions, enabling automatic further folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the connecting assembly is designed to remain stationary during folding, then the stroller frame can be folded compactly, but the connecting assembly does not fold with the stroller frame resulting in a less compact design
Solution Approach 1:
The patent merges the connecting assembly with the rotating base through a unified rotational mechanism. The connecting assembly is pivotally connected to the rotating base, allowing both to rotate together as an integrated unit during the folding operation, achieving compact folding without requiring separate disassembly
Solution Approach 2:
The patent introduces a dynamic locking mechanism that transitions between locked and unlocked states during folding. The locking assembly automatically unlocks when the pivot joint mechanism transitions to the folded state, enabling the connecting assembly to rotate dynamically with the stroller frame rather than remaining stationary
2Ease of operation
If the connecting assembly is designed to fold automatically, then operational convenience is improved, but the structure becomes more complex requiring additional locking and driving mechanisms
Solution Approach 1:
The patent incorporates a pre-configured driving member with elastic force that is ready to activate automatically when the pivot joint mechanism transitions to the folded state. The locking assembly is pre-positioned to unlock at the appropriate moment, eliminating the need for separate manual operation while maintaining a relatively simple structure
Solution Approach 2:
The folding mechanism is designed to be self-activating through the elastic force of the driving member and the automatic unlocking of the locking assembly. When the pivot joint mechanism transitions to the folded state, these components automatically drive the rotating base and connecting assembly to rotate, without requiring external control or complex additional mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The folding device achieves a simple structure that automatically performs further folding, improving operational convenience and compactness by ensuring the connecting assembly rotates with the stroller frame.
Implementation Method 1
an elastic force of the first elastic member provides the rotating base with a movement tendency to rotate in the first rotating direction

AI summary
A folding device and a stroller are provided. The folding device includes a pivot joint mechanism, a rotating base, and a locking assembly. The pivot joint mechanism is provided with a driving member and is switchable between an unfolded state and a folded state. The rotating base is pivotally connected to the pivot joint mechanism. The rotating base is provided with a driven portion. The locking assembly is movably connected to the pivot joint mechanism or the rotating base. The locking assembly has a locking position and an unlocking position. When the pivot joint mechanism switches from the unfolded state to the folded state, the pivot joint mechanism drives the locking assembly to move from the locking position to the unlocking position, and when the locking assembly is in the unlocking position, the driving member drives the driven portion to move to cause the rotating base to rotate.
