Child Door Lock U-Bracket for Damage-Free Dual-Side Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional child locks are limited in adaptability and effectiveness, compromising their utility in diverse home settings, and often require damage to doors during installation.
Innovation Solution
A versatile and secure child lock mechanism that can be easily installed without damaging doors, featuring a catch mechanism and release mechanism connected by a U bracket, allowing installation on any door edge and enabling operation from both sides, with components that can be attached using tools or adhesives for added security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional child locks are used, then the locking function is provided, but the adaptability to diverse home settings is limited
Solution Approach 1:
The lock mechanism is designed with a U-bracket that can be positioned at multiple locations around the door perimeter (top, bottom, sides) and accommodates various door thicknesses and styles. The adjustable positioning holes and flexible installation methods enable the same lock device to function effectively across diverse home settings, from interior to exterior doors, without requiring multiple specialized lock types.
2Reliability
If secure locking mechanism is implemented, then the door security is improved, but the ease of opening from both sides is reduced
Solution Approach 1:
The lock mechanism is divided into separate functional components: a catch member that engages with the door frame for security, and a release member accessible from either side of the door. The U-bracket structure separates the locking function (catch engaging with frame) from the releasing function (pull tabs accessible from both sides), allowing the door to be securely locked when closed but easily opened from either side by accessing the appropriate release mechanism.
Solution Approach 2:
The U-bracket serves as an intermediary structure that connects the catch mechanism to the door while allowing access to release mechanisms from both sides. It mediates between the security requirement (catch engaged with frame) and the accessibility requirement (release buttons reachable from either side), enabling the door to remain secure when closed but accessible when needed.
3Adaptability or versatility
If the lock mechanism is made versatile and adjustable, then the adaptability to various door installations is improved, but the device complexity increases
Solution Approach 1:
The lock mechanism incorporates adjustable elements including multiple positioning holes in the U-bracket for different door thicknesses, movable catch positions, and flexible mounting options. These dynamic, adjustable features allow the same basic lock design to adapt to various door installations without requiring complex specialized components for each door type, achieving versatility through simple adjustable elements rather than complex fixed designs.

AI summary
A door lock system includes a first component mounted on one side of a door and a second component mounted on the opposite side. The system features a structure that mechanically connects the two components, designed to pass through the gap between the closed door and its frame. Additionally, the system incorporates a communication link between the first and second components.
