Solution Overview
Problem
Existing gate locking devices can be easily unlocked by children, compromising safety due to their simple operation.
Innovation Solution
A mesh type gate with a reel locking device featuring an automatic locking mechanism and a resettable manual unlocking slider, combined with an elastic pressing mechanism that requires a two-step operation for unlocking, making it difficult for children to unlock the gate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple manual unlocking mechanism is used, then the device complexity is reduced, but the safety control is compromised as children can easily unlock it
Solution Approach 1:
The unlocking mechanism is divided into two separate operational steps: first pressing the pressing member (51) to release the blocking state, then moving the manual unlocking slider (41) to unlock the reel. This segmentation prevents children from accidentally or easily unlocking the gate, as they would need to comprehend and execute both steps in sequence
Solution Approach 2:
The pressing member (51) must be pressed first to change the blocking state of the manual unlocking slider (41) before the slider can be moved to unlock the reel. This preliminary action ensures that the unlocking process is deliberate and controlled, enhancing safety while maintaining manageable device complexity
2Reliability
If an automatic locking mechanism is added to prevent free rotation, then the safety control is improved, but the device complexity increases
Solution Approach 1:
The automatic locking mechanism uses a synchronization member (31) that automatically engages with the reel (3) to prevent free rotation, and a movable block (42) that automatically blocks the manual unlocking slider (41) from moving. The elastic pressing mechanism (51, 52) automatically resets the blocking state after unlocking. This self-service approach provides reliable safety control without requiring complex external control systems or additional power sources
3Reliability
If the pressing member is designed to hinder slider movement both when not pressed and after resetting, then the safety control is enhanced, but the ease of operation is reduced
Solution Approach 1:
The pressing member (51) dynamically changes the blocking state of the manual unlocking slider (41). When pressed, it releases the blocking to allow slider movement for unlocking. When not pressed and after resetting, it restores the blocking state to prevent unauthorized operation. This dynamic state change provides enhanced safety control while maintaining ease of operation for authorized users who know the correct two-step sequence
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides enhanced safety control by preventing free rotation of the synchronization member and vertical reel, while allowing easy manual unlocking for adults, thus ensuring the gate remains locked unless intentionally unlocked, thereby preventing unauthorized access.
Implementation Method 1
an elastic pressing mechanism for obstructing the movement of the manual unlocking slider. The elastic pressing mechanism includes a pressing member that does not obstruct the movement of the manual unlocking slider after being pressed, and that hinders the movement of the manual unlocking slider both when it is not pressed down and after resetting

AI summary
A reel locking device includes: a reel seat; a vertical reel rotatably connected to the reel seat and used for retracting and releasing a gate mesh; a synchronization member fixedly connected to one end of the vertical reel; an automatic locking mechanism that prevents the synchronization member from rotating freely and that includes a resettable manual unlocking slider; and an elastic pressing mechanism that obstructs the movement of the manual unlocking slider and that includes a pressing member that does not obstruct the movement of the manual unlocking slider after being pressed, and that when not pressed or after resetting obstructs the movement of the manual unlocking slider. A mesh type gate is further disclosed including the above reel seat on one side and a buckle seat on another side, where a free end of the gate mesh includes a pull ring for being fastened to the buckle seat.
