Stroller Unlock Assembly Combining 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 affect the aesthetic appeal, reducing consumer interest.
Innovation Solution
An unlock device with at least one operating member, a first unlock module, and a second unlock module, which are movably disposed on the frame to independently unlock the 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 device occupies much space and the operation becomes inconvenient
Solution Approach 1:
The patent combines the frame folding mechanism and wheel rotation orientation mechanism into a single integrated locking system. A unified locking component can simultaneously lock both the frame folding structure and the wheel rotation orientation, reducing the number of separate mechanisms needed while maintaining reliable locking function for both operations.
Solution Approach 2:
The locking mechanism is designed with multi-functionality to serve both frame folding and wheel rotation orientation purposes. The same locking component can engage with different structures depending on the operational mode, allowing one mechanism to perform multiple functions that previously required separate dedicated mechanisms.
2Reliability
If multiple separate mechanisms are installed for frame folding and wheel rotation orientation, then each function can be performed independently, but the stroller becomes unsightly and consumer purchase intention reduces
Solution Approach 1:
By merging the frame folding mechanism and wheel rotation orientation mechanism into a single integrated system, the patent reduces the number of visible separate components on the stroller. This consolidation creates a cleaner, more streamlined appearance while maintaining all necessary locking functions, thereby improving aesthetic appearance without sacrificing reliability.
3Reliability
If separate mechanisms are used for frame folding and wheel rotation orientation, then each mechanism can be optimized for its specific function, but the device complexity increases and space occupation increases
Solution Approach 1:
The patent integrates multiple locking functions into a single unified mechanism, reducing device complexity by eliminating redundant components. The combined mechanism uses a single locking component that can engage with both the frame folding structure and wheel rotation orientation structure, simplifying the overall system while maintaining reliable locking capability for both functions.

AI summary
An unlock device comprising: at least one operating member movably disposed on a frame, the frame being equipped with a first lock mechanism and a second lock mechanism; a first unlock module movably disposed on the frame and connected to the first lock mechanism; and a second unlock module movably disposed on the frame and connected to the second lock mechanism; a selecting member movably disposed on the frame, wherein the first and second unlock modules are moved with the selecting member, and the at least one operating member is able to move to drive the first unlock module to unlock the first lock mechanism or drive the second unlock module to unlock the second lock mechanism.
