Childproof Gate Lock with Rotating Core and Bolt Slot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gate locks with simple latches can be easily opened by smart children, rendering them ineffective in preventing children or pets from escaping.
Innovation Solution
A childproof gate lock design featuring a lock base, lock core with a slot, a latch member, and a bolt assembly, where the bolt is engaged in the slot when the gate is closed and requires a 90-degree rotation of the lock core to unlock, ensuring secure locking and unlocking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If simple latches or locking devices are used to secure gates, then the gate can be easily opened, but the gate becomes ineffective in protecting children or pets
Solution Approach 1:
The lock core is designed to rotate between locked and unlocked positions, dynamically changing the engagement state of the bolt with the slot. This dynamic mechanism ensures the gate remains securely locked during normal use but can be intentionally opened when needed
Solution Approach 2:
The locking mechanism is divided into distinct functional components: the bolt assembly for engagement, the lock core for rotation control, and the slot for positioning. This segmentation allows each component to perform its specific function effectively, creating a reliable yet operable locking system
2Reliability
If a 90-degree rotation mechanism is implemented in the lock core, then the gate locking reliability is improved, but the device complexity increases
Solution Approach 1:
The rotation and locking functions are merged into a single lock core component that performs both operations through its rotational motion. This consolidation reduces the need for separate mechanisms while maintaining the 90-degree rotation security feature
Solution Approach 2:
The lock core serves multiple functions: it controls the bolt engagement, provides the 90-degree rotation security mechanism, and enables gate opening when rotated. This multi-functionality reduces overall device complexity by eliminating the need for separate components for each function

AI summary
A gate lock is composed of a lock base, a lock core with a slot defined therein, a latch member and a bolt assembly. A gate is mounted in a frame, which can be mounted in a doorway. The gate lock is mounted on the gate and the bolt assembly of the gate lock is mounted on the frame. When the gate is closed, the bolt is engaged in the slot in the lock core. The lock core is then rotated 90 degrees. The bolt will not slide out of the slot, and the gate is locked. To unlock the gate, the lock core is rotated 90 degrees in the opposite direction. The gate is then lifted upward allowing the bolt to slide out of the slot, thus enabling the gate to swing open.
