Stroller Unlock Mechanism for Folding and Wheel Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stroller designs are cumbersome and inconvenient due to space-occupying mechanisms for folding and wheel orientation, which affect usability and aesthetics, potentially reducing consumer interest.
Innovation Solution
An unlock device with a selecting member that moves between positions to drive either a frame folding mechanism or a wheel rotation orientation mechanism, using sliding and rotating members to unlock these mechanisms efficiently, thereby simplifying operation and reducing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional separate mechanisms are used for frame folding and wheel orientation, then each mechanism can perform its function reliably, but the device occupies much space and the operation becomes extremely inconvenient
Solution Approach 1:
The patent combines the frame folding mechanism and wheel orientation mechanism into a single integrated mechanism. The locking pin serves dual functions: it locks the frame during folding operations and locks the wheel during orientation changes. This merging of functions reduces the number of separate mechanisms from two to one, directly addressing the contradiction by improving ease of operation while reducing device complexity
Solution Approach 2:
The locking pin is designed as a universal component that performs multiple functions across different operational modes. It acts as both a frame lock and a wheel lock depending on the operational context. This multi-functionality allows a single component to replace what would traditionally require separate dedicated components, thereby simplifying the overall device structure and improving operational convenience
2Reliability
If traditional separate mechanisms are used for frame folding and wheel orientation, then each mechanism can perform its function reliably, but the mechanisms occupy much space of the stroller
Solution Approach 1:
By merging the frame folding mechanism and wheel orientation mechanism into a single integrated system, the patent reduces the total volume occupied by these mechanisms. Instead of having two separate mechanisms each requiring their own space, one integrated mechanism performs both functions, directly reducing the space occupation while maintaining the reliability of both functions through proper mechanical design
3Adaptability or versatility
If traditional mechanisms are used for folding and wheel orientation, then the functions can be achieved, but the stroller is unsightly and purchase intention reduces
Solution Approach 1:
The patent extracts the essential locking function from complex traditional mechanisms and implements it through a simplified locking pin system. This extraction of the core function eliminates unnecessary mechanical complexity and visible bulky components, resulting in a cleaner, more aesthetically pleasing stroller design while preserving the full functional capability of frame folding and wheel orientation

AI summary
An unlock device (1) includes at least one operating member (11, 111, 112), a first unlock module (13) and a second unlock module (14). The at least one operating member (11, 111, 112) is movably disposed on a frame (2), wherein the frame (2) is equipped with a first lock mechanism (4) and a second lock mechanism (5). The first unlock module (13) is movably disposed on the frame (2) and connected to the first lock mechanism (4). The second unlock module (14) is movably disposed on the frame (2) and connected to the second lock mechanism (14). The at least one operating member (11, 111, 112) moves to drive the first unlock module (13) to move to unlock the first lock mechanism (4) or drive the second unlock module (14) to move to unlock the second lock mechanism (5).
