Foldable Child Carrier Locking Mechanism for Safe Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant strollers with detachable seat portions face inconvenience due to their large size and the complexity of assembly and disassembly, which complicates sanitation and reuse.
Innovation Solution
A foldable child carrier with a seat portion pivotally connected to a stroller frame, featuring a lock mechanism and an actuator member that allows the seat portion to rotate relative to the frame only when the back-resting portion is in a folded position, ensuring secure locking and easy unfolding for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the seat portion is detachable from the stroller frame, then sanitation and reuse become more convenient, but the device size and assembly complexity increase
Solution Approach 1:
The seat portion is divided into separable components that can be detached from the stroller frame. The lock mechanism includes a lock member on the seat portion and a corresponding locking structure on the frame, allowing easy separation while maintaining structural integrity during use.
Solution Approach 2:
The lock mechanism is extracted as a separate functional component with an actuator member that can be operated to release the lock. This allows the seat portion to be easily removed from the frame without requiring complex tools or procedures.
2Device complexity
If the seat portion is fixedly joined to the stroller frame, then assembly simplicity is maintained, but sanitation and reuse convenience are reduced
Solution Approach 1:
The connection between seat portion and frame is segmented into a lockable/unlockable interface rather than a permanent fixed joint. The lock member engages with the frame structure to provide secure attachment when locked, and can be easily disengaged for separation when unlocked.
3Ease of operation
If the actuator member can release the lock mechanism at any position, then operation flexibility is improved, but safety and reliability are reduced
Solution Approach 1:
The system prevents premature or incorrect operation by requiring the back-resting portion to be in a specific folded position before the actuator member can release the lock mechanism. This preliminary condition ensures the seat is properly positioned and reduces the risk of accidental release during use.
Solution Approach 2:
The mechanical structure provides feedback through the positioning of the back-resting portion. Only when the back-resting portion is correctly folded does the actuator member gain the mechanical advantage or access needed to engage the lock release, providing inherent feedback on the correct operational state.
4Adaptability or versatility
If the seat portion rotates relative to the stroller frame, then portability and storage are improved, but structural stability may be compromised
Solution Approach 1:
The connection between seat portion and frame transitions from a static fixed joint to a dynamic pivotable connection. The seat portion can rotate relative to the frame around a pivot axis, allowing adjustment for portability and compact storage, while the lock mechanism provides static stability when locked in the operational position.

AI summary
A foldable child carrier includes a seat portion pivotally connected to a stroller frame and a back-resting portion in a folded configuration relative to the seat portion; a lock mechanism between the seat portion and the stroller frame to lock up the position of the seat portion relative to the stroller frame; a movable actuator member between the seat portion and the back-resting portion; the actuator member being unable to release the lock mechanism when the back-resting portion is in a reclined position; and the movement of the actuator member allowing the lock mechanism to release the seat portion and the stroller frame when the back-resting portion is in a folded position, so that the seat portion can rotate relative to the stroller frame. The foldable child carrier of the present disclosure has at least such features as novel structure, user-friendliness, safety and liability, and easy portability and storage.
