Baby Carrier Frame Locking Mechanism Hiding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frame folding and fixing mechanisms for baby carriers are aesthetically poor, pose safety risks due to exposed components, and increase production costs with separate manufacturing and assembly.
Innovation Solution
A frame folding and fixing device integrated within the joint of a baby carrier, featuring first and second locking devices that rotate to lock and unlock the handle and front leg, eliminating the need for external components and enhancing aesthetics and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a frame folding and fixing hook is provided to lock the folded state, then the folded state can be locked and prevented from opening undesirably, but the exposed hook has poor aesthetics and poses safety risks
Solution Approach 1:
The locking mechanism is nested within the joint structure itself. The joint contains internal locking components (locking protrusions and locking grooves) that are hidden within the joint housing, eliminating the need for external exposed hooks while maintaining reliable locking functionality.
Solution Approach 2:
The locking function is merged with the joint structure. Instead of being a separate external component, the locking mechanism is integrated into the joint between handle and front leg, combining the structural connection and locking functions into a single unified component.
2Reliability
If a frame folding and fixing hook is provided separately and connected to the baby carrier, then the locking function is achieved, but the manufacture processes and production cost increase
Solution Approach 1:
The locking function is merged with the joint structure. Instead of being a separate external component, the locking mechanism is integrated into the joint between handle and front leg, combining the structural connection and locking functions into a single unified component that is manufactured as one piece.
Solution Approach 2:
The joint structure serves multiple functions simultaneously: it provides the structural connection between handle and front leg, enables folding motion, and incorporates the locking mechanism. This multi-functionality eliminates the need for separate locking components and simplifies manufacturing.
3Ease of operation
If the frame folding and fixing hook is exposed to the outside, then the locking mechanism is accessible, but it naturally hangs down and creates safety hazards
Solution Approach 1:
The locking mechanism is nested within the joint housing, making it inaccessible as an external hanging component while remaining accessible for operation through the designed joint interface. This eliminates the safety hazard of exposed hanging hooks.
Solution Approach 2:
The joint housing acts as an intermediary that encloses the locking components. Users interact with the locking mechanism through the joint interface rather than directly with exposed hooks, mediating the interaction to eliminate safety hazards while maintaining operability.

AI summary
A frame folding and fixing device and a baby carrier are provided. The frame folding and fixing device includes a first locking device on a front leg of a frame and a second locking device on a handle of the frame. When the front leg of the frame is folded relative to the handle of the frame, the first locking device and the second locking device are rotated towards each other and locked; when the front leg of the frame is unfolded relative to the handle of the frame, the first locking device and the second locking device are rotated away from each other and unlocked. The frame folding and fixing device according to the disclosure may improve the overall aesthetics and use safety of the baby carrier, and may have a simple structure, low production cost and more convenient operation.
