Stroller Unlock Mechanism Integrating Folding and Wheel Orientation Locks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strollers have mechanisms that occupy significant space, are inconvenient to operate, and detract from their aesthetic appeal due to complex folding and wheel orientation mechanisms.
Innovation Solution
An unlock device with at least one operating member and two unlock modules that can selectively unlock frame folding and wheel rotation orientation mechanisms, reducing the need for separate devices and simplifying operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate mechanisms are used for frame folding and wheel rotation orientation, then each mechanism can perform its specific function reliably, but the stroller occupies more space and becomes more complex in structure
Solution Approach 1:
The patent combines the frame folding lock mechanism and wheel rotation orientation lock mechanism into a single integrated lock mechanism. The operating member is connected to both lock mechanisms through the unlocking device, allowing one unified structure to control both functions that were previously separate, thereby reducing overall structural complexity while maintaining reliability
Solution Approach 2:
The integrated lock mechanism serves multiple functions: it can lock and unlock both the frame folding mechanism and the wheel rotation orientation mechanism. The single operating member and unlocking device provide universal control over multiple stroller functions, eliminating the need for separate dedicated mechanisms for each function
2Reliability
If separate mechanisms are used for frame folding and wheel rotation orientation, then each mechanism can be optimized for its function, but the operation becomes more inconvenient and requires multiple controls
Solution Approach 1:
The patent merges the control of frame folding and wheel rotation orientation into a single operating member. This unified control interface allows the user to operate both lock mechanisms simultaneously or independently through one control action, greatly improving ease of operation compared to managing separate controls for each function
3Reliability
If complex mechanisms are installed in the stroller, then the locking and orientation functions can be achieved, but the stroller becomes unsightly and reduces consumer purchase intention
Solution Approach 1:
By integrating multiple lock mechanisms into one unified structure, the patent reduces the number of visible components on the stroller. This consolidation creates a cleaner, more streamlined appearance compared to having separate mechanisms scattered throughout the stroller structure, thereby improving aesthetic appearance while maintaining functional reliability

AI summary
An unlock device comprises at least one operating member movably disposed on a frame, the frame being equipped with at least one lock mechanism; a retaining mechanism disposed on the at least one operating member; and at least one unlock module movably disposed on the frame and connected to the at least one lock mechanism; wherein, when the at least one operating member moves to drive the at least one unlock module to move to unlock the at least one lock mechanism, the retaining mechanism retains the at least one operating member at an unlock position.
