Stroller Locking Device Sliding Latch Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking devices for strollers are complex and inconvenient to operate, often failing to function properly due to their intricate configurations.
Innovation Solution
A locking device comprising an articulated mechanism with a sliding locking member and flexible latch, pivotally connected between side frames and a base frame, allowing for easy folding and unfolding of the stroller by sliding the latch or protrusion to enable or prevent movement of the side frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex locking mechanism with multiple components is used, then the locking reliability is improved, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent combines the locking member and latch into a single integrated component that slides along the articulated mechanism. This merging of functions maintains reliable locking through the engagement of the latch with the articulated mechanism while eliminating separate locking components, thereby reducing device complexity and improving ease of operation.
Solution Approach 2:
The patent extracts the essential locking function from a complex multi-component system and isolates it into a simple sliding latch mechanism. By taking out only the necessary elements (the sliding latch and its engagement point on the articulated mechanism), the design achieves reliable locking without the burden of unnecessary components.
2Ease of operation
If a simple locking mechanism is used, then the device complexity is reduced and ease of operation is improved, but the locking reliability deteriorates
Solution Approach 1:
The patent employs a dynamic sliding latch mechanism that can easily move between locked and unlocked positions along the articulated mechanism. This dynamic design allows simple one-handed operation while maintaining reliable locking through the geometric constraint of the latch engaging with the articulated mechanism's structure.
Solution Approach 2:
The sliding latch mechanism is designed to be self-locking through its geometric configuration, where the latch naturally engages with the articulated mechanism when slid into position. This self-service feature ensures reliable locking without requiring additional locking actions or complex mechanisms, maintaining both simplicity and reliability.
3Reliability
If multiple locking components are used, then the locking reliability is improved, but the ease of repair deteriorates
Solution Approach 1:
By extracting the locking function into a single removable sliding latch component, the patent makes repair straightforward. If the latch fails, it can be easily removed and replaced without disassembling other parts of the folding mechanism, maintaining reliability while significantly improving ease of repair compared to multi-component systems.

AI summary
A locking device for a stroller is provided. The stroller includes a pair of side frames and a base frame. The locking device comprises an articulated mechanism pivotally connected between the respective rear frames of the pair of side frames, a locking member slidably provided on the articulated mechanism for locking the articulated mechanism, and a pair of side braces pivotally connected to the locking member at one end thereof respectively and pivotally connected to the respective rear frames of the pair of side frames at the other end thereof. The folding and unfolding of the stroller can be easily carried out by means of the locking device.
