Foldable Locking Mechanism for Simultaneous Multi-Rod Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable locking mechanisms for child carriers have complex structures and are inconvenient to use, as they require users to bend down to operate the release button and cannot unlock multiple rods simultaneously.
Innovation Solution
A foldable locking mechanism with a simple structure, comprising a first mounting seat, a second mounting seat, a third mounting seat, a first locking component, and a driving component, which allows simultaneous unlocking of multiple rods by moving the first locking component to a releasing position using the driving component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional locking device with a releasing button is used, then the locking function is achieved, but the user must bend down to operate it, reducing ease of operation
Solution Approach 1:
The release button is moved from a low position requiring bending to the handle area at a higher, more accessible position. The releasing component is integrated into the handle assembly, allowing users to operate it while standing upright, thus improving ease of operation without significantly increasing device complexity.
Solution Approach 2:
The locking and releasing mechanism is designed to be automatically actuated through the existing folding motion of the frame. When the frame is folded, the relative movement between frame parts automatically triggers the locking component to engage or disengage, reducing the need for manual intervention and improving ease of operation.
2Productivity
If a conventional locking device is used, then individual rods can be locked, but multiple rods cannot be unlocked simultaneously, reducing productivity
Solution Approach 1:
Multiple locking functions for different frame rods are merged into a single integrated locking mechanism. The locking component can simultaneously engage or disengage multiple locking points through a single release button operation, enabling simultaneous unlocking of multiple rods and significantly improving folding efficiency.
Solution Approach 2:
The locking mechanism is designed with multi-functionality to handle both locking and releasing operations for multiple frame components through a single mechanism. The release button actuates a releasing component that can interact with multiple locking points, allowing one operation to perform multiple functions of unlocking several rods at once.
3Device complexity
If a releasing button mechanism is used, then locking control is achieved, but the structure becomes complicated, increasing device complexity
Solution Approach 1:
The complex releasing button mechanism from conventional designs is extracted and replaced with a simplified releasing component integrated into the handle assembly. The design removes unnecessary intermediate components and simplifies the actuation path, reducing device complexity while maintaining or improving locking reliability through more direct mechanical engagement.

AI summary
A foldable locking mechanism (300, 500) adapted for a frame body (400) includes a first mounting seat (1), a second mounting seat (2), a third mounting seat (4), a first locking component (3) and a driving component (1a, 2a). The second mounting seat (2) is pivotally connected to the first mounting seat (1) and the third mounting seat (4). The first locking component (3) is at least partially disposed between the second mounting seat (2) and the third mounting seat (4) and movable between a first releasing position and a first locking position for allowing or restraining a relative pivotal movement of the second mounting seat (2) and the third mounting seat (4). The driving component (1a, 2a) is disposed on the first mounting seat (1) and abuts against the first locking component (3). The driving component (1a, 2a) is configured to drive the first locking component (3) to move to the first releasing position to allow a folding operation of the foldable locking mechanism (300, 500) for allowing a folding operation of the frame body (400).
