Double-Latch Child Gate to Prevent Accidental Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child proof gates can be inadvertently opened by accidental activation of electronic sensors, posing a safety risk, especially when users come close to the gate frame.
Innovation Solution
A child proof gate with a U-shaped frame and dual locking assemblies, featuring a manually or voice-activated button to actuate the first locking assembly and a spring-biased second locking assembly, which requires sequential foot pedal operation to open, ensuring secure and hands-free operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electronic sensors are used to open the gate, then hands-free operation is achieved, but accidental activation occurs when users come too close
Solution Approach 1:
The gate opening mechanism is divided into two separate systems: a first locking assembly with a button actuator for manual/voice activation, and a second locking assembly with a foot pedal actuator for hands-free activation. This segmentation allows each system to have its own activation zone, preventing interference between them and eliminating accidental activation while maintaining hands-free operation capability.
Solution Approach 2:
The activation mechanisms are positioned at different vertical levels and spatial zones. The button is disposed apart from and above the first locking assembly, while the foot pedal is positioned at a different location. This spatial dimensionality separation ensures that proximity to one activation point does not trigger the other, resolving the accidental activation issue.
2Device complexity
If a single locking assembly is used, then device complexity is reduced, but security and control are insufficient
Solution Approach 1:
The locking mechanism is segmented into two independent locking assemblies, each with its own actuator and control logic. The first locking assembly uses a button actuator that can be manually or voice-activated, while the second locking assembly uses a foot pedal actuator. This segmentation provides redundant security control and allows for differentiated activation methods without significantly increasing overall system complexity.
Solution Approach 2:
Each locking assembly has localized activation characteristics tailored to its function. The first locking assembly responds to manual or voice commands, while the second responds to foot pedal depression. This local differentiation in activation quality allows each assembly to serve its specific security function optimally.

AI summary
A child proof gate includes a U-shaped frame configured to be pressure fit between two opposing flat surfaces, wherein the frame comprises a first locking assembly, a second locking assembly, and a button that is configured to be manually; wherein the manually activated button is disposed apart from and above the first locking assembly and wherein the button, when manually activated, is configured to electrically actuate the first locking assembly and to move the first locking assembly from a closed position to an open position for a predetermined period of time. The gate may also include a door including an upper mating door latch and a lower mating door latch; wherein the upper mating door latch is configured to be removably attached to the first locking assembly when the door is in a closed position.
