Friction-Attached Childproof Latch for Cabinets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing childproof latches for cabinets and drawers face issues with adhesion methods that are not long-lasting and damage surfaces, while screw-based methods require skill and may permanently mar the furniture, and there is a lack of adjustment mechanisms for varying drawer or cabinet configurations.
Innovation Solution
A friction-attached childproof latch with adjustable connectors, such as hooks, staples, and snap fasteners, allowing for secure attachment without damage and accommodating different configurations through extension pieces and slide/rail mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If adhesive pads are used to attach childproof latches, then installation is simple and no damage is caused to surfaces, but the attachment is not long-lasting and requires 24 hours of cure time
Solution Approach 1:
The patent replaces adhesive pads with a friction-attachment mechanism that uses mechanical friction between the latch body and the cabinet/drawer surface. The friction-attached latch features a body with a friction surface that contacts the furniture surface, providing secure attachment without chemicals or curing time requirements, while maintaining ease of installation and removal.
2Strength
If drilling and screws are used to attach childproof latches, then the attachment is strong and permanent, but the surfaces of cabinets or drawers may be permanently damaged
Solution Approach 1:
The patent replaces drilling and screwing with a friction-attachment system where the latch body is held in place by friction against the cabinet or drawer surface. This eliminates the need for penetration or fasteners that could damage the furniture surface, while still providing sufficient attachment strength through the friction interface and adjustable jaw mechanism.
Solution Approach 2:
The patent uses an adjustable jaw mechanism with a screw that allows the latch to adapt to different positions on the furniture surface. The jaw can be adjusted along the screw to accommodate varying drawer or cabinet configurations, changing the positional parameters to achieve proper alignment without requiring permanent modification to the furniture.
3Reliability
If standard childproof latches are used, then the basic latching function is provided, but there is no way to properly line two pieces for certain drawer or cabinet configurations
Solution Approach 1:
The patent incorporates an adjustable jaw mechanism that can dynamically reposition along the latch body to accommodate different drawer or cabinet configurations. The jaw can be moved along the screw to adjust the spacing and alignment, allowing the same latch design to properly line up with various furniture configurations while maintaining reliable latching function.
Solution Approach 2:
The latch is divided into separable components including the body, adjustable jaw, and connector halves that can be independently positioned and adjusted. This segmentation allows each component to be optimized for its specific function while collectively providing versatility across different furniture configurations.
4Ease of operation
If adhesive pads are used to attach childproof latches, then no skill level is required for installation, but the pads cannot be reused and may be hard to remove
Solution Approach 1:
The patent replaces adhesive pads with a friction-attachment mechanism that uses mechanical friction for both attachment and removal. The friction interface provides secure holding during use but allows easy removal by applying gentle force, eliminating the need for chemical curing time and enabling reuse of the latch without damage to the furniture surface.

AI summary
The present disclosure teaches a friction-attached childproof latch for cabinets and drawers. Wherein, each half of the childproof latch includes a C-shaped frame with one top surface and two side surfaces, and a jaw is placed between the side surfaces, and connected to one of the side surfaces via a screw. The jaw may move with regard to the frame along the screw by tightening or loosening the screw. A panel of a cabinet or drawer may be friction-attached between the jaw and an opposite side surface of the frame. A first connector may be placed onto any surface of the frame, or connected to the frame via an extension piece. Wherein, the first connector may removably connect to a second connector placed on the other half of the latch. These connectors may take various forms, such as a hook and staple, a tether connection, or a snap fastener.
