Foldable Locking Mechanism for Simultaneous Frame Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable frame locking mechanisms for child carriers, such as strollers, have complex structures and require users to bend down to operate release buttons, making them inconvenient for unlocking multiple rods simultaneously.
Innovation Solution
A foldable locking mechanism with a simple structure that allows simultaneous unlocking of multiple rods by using a driving component to move locking components to releasing positions, enabling easy operation without bending down, through a series of pivotally connected mounting seats and resilient components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional locking device with multiple release buttons is used to lock multiple rods, then the locking function is achieved, but the structure becomes complicated and the operation becomes inconvenient requiring users to bend down
Solution Approach 1:
The patent combines multiple locking functions into a single integrated locking component that can lock multiple rods simultaneously. The locking component includes multiple locking arms that can engage with different rods, and a single release button controls all locking arms through a connected structure, merging multiple locking operations into one unified mechanism.
Solution Approach 2:
The locking component is designed with multi-functionality to perform multiple locking operations. The same locking component can lock different rods (front leg, rear leg, handle) at different stages of the folding process, and the release mechanism can unlock all rods simultaneously, making the device universal for various locking needs without requiring separate buttons for each rod.

The locking component includes multiple locking arms that can engage with different rods, and a single release button controls all locking arms through a connected structure, merging multiple locking operations into one unified mechanism.
Solution Approach 2:
The locking mechanism incorporates a spring-loaded release system where pressing the release button triggers a self-propagating unlocking sequence. The first locking arm unlocks automatically, which then triggers the second locking arm to unlock, and so on, allowing the mechanism to service itself through the initial button press without requiring the user to manually operate multiple separate buttons.
3Reliability
If a conventional locking device with multiple release buttons is used, then multiple rods can be locked, but the device cannot unlock the rods simultaneously and requires multiple operations
Solution Approach 1:
The patent implements a continuous unlocking action through a chain-reaction mechanism. When the release button is pressed, it triggers the first locking arm to move, which through a connected structure automatically triggers the second locking arm, and subsequently the third locking arm, creating an uninterrupted sequence of unlocking actions that completes the entire unlocking process in one continuous motion rather than requiring separate discrete operations.
Solution Approach 2:
The patent extracts the complexity of multiple separate unlocking operations and consolidates it into a single release button mechanism. By removing the need for multiple independent buttons and their associated control mechanisms, the design simplifies the operation to a single action that extracts and performs all necessary unlocking functions simultaneously.

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).
