Screen Wall Mount with Folded-Sheet Auto-Lock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall mount designs for large screens are prone to accidental dislodging due to the difficulty in accessing and securing screws, leading to potential damage and safety hazards, and often require additional expensive components and complex assembly processes.
Innovation Solution
A wall mounting kit featuring a wall mount frame with an upper and lower rail system, where screen hook interfaces lock onto both rails using a groove and inclined nose mechanism, distributing the screen's weight evenly and preventing accidental falls without requiring additional elements or complex assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw locking mechanism is used to secure the screen hook interface to the wall mount frame, then the screen can be firmly fixed to the wall, but the screw becomes difficult to access once the screen is mounted, making it hard to lock or unlock
Solution Approach 1:
A release tool serves as an intermediary device to access and operate the set screw from the front of the screen. The tool includes a rod with a head that fits into a recess, allowing the screw to be locked or unlocked without requiring direct access to the screw head behind the screen.
Solution Approach 2:
The release tool is designed to fit into a recess in the screen hook interface, with the rod portion extending through to engage the set screw. This nested structure allows the release mechanism to be stored within the screen hook interface when not in use.
2Ease of operation
If a tooth and spring locking mechanism is used to automatically lock the screen hook interface, then the locking process is simplified, but additional expensive components and complex assembly are required
Solution Approach 1:
The patent removes the tooth and spring components from the locking mechanism, retaining only the essential set screw for securing the screen hook interface to the wall mount frame. This simplifies the device while maintaining reliable locking capability.
Solution Approach 2:
The set screw is positioned and oriented such that it can be accessed and operated through a recess in the screen hook interface using a simple release tool, eliminating the need for complex automatic locking mechanisms while still providing secure fixation.
3Device complexity
If the entire screen weight is supported by the upper bar of the wall mount frame, then the structure is simpler, but the lower bar only serves for stabilization and locking without bearing weight
Solution Approach 1:
The wall mount frame is divided into an upper bar and a lower bar, with the set screw positioned on the lower bar to provide additional anchoring. This segmentation allows the lower bar to contribute to both stabilization and secure locking, improving overall reliability.

AI summary
A wall mounting kit for mounting a screen on a wall, including a wall mount frame configured to be attached to the wall, one or more screen hook interfaces that are configured to be coupled to the screen and enable hanging the screen onto the wall mount frame, wherein the screen hook interfaces lock onto the wall mount frame so that the screen will not accidentally fall off by applying a force in a single direction; and wherein the screen hook interfaces are each formed by folding a cut out piece of a sheet of material without requiring additional elements to lock onto the wall mount frame.
