Supporting Frame Latch Assembly for Tool-Free Wall Bracket Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional supporting frames require the use of a hexagonal wrench to loosen or tighten set screws for installation or removal, which is inconvenient, time-consuming, and often obstructed by the wall, making operation difficult.
Innovation Solution
A supporting frame assembly with a latch and elastic component that allows for tool-free attachment and detachment by rotating between locking and unlocking positions, using an elastic force to secure the frame to a bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a set screw is used to secure the supporting frame to the bracket, then the supporting frame can be firmly fixed, but the installation and removal process becomes time-consuming and requires a hexagonal wrench
Solution Approach 1:
The fixing mechanism is segmented into a latch component with a latching end and an operation end, allowing independent operation for locking and unlocking. The latch can be rotated to different positions (locked, unlocked, intermediate) to provide both secure fixing and quick release functionality without requiring tools
Solution Approach 2:
The supporting frame incorporates a self-servicing fixing mechanism where the latch can be directly operated by hand to lock and unlock the frame to the bracket. The elastic component provides automatic return force to the latching end, enabling the frame to be securely fixed without external tools while allowing quick manual release
2Strength
If a set screw is used to secure the supporting frame, then the frame can be firmly attached, but the operation becomes difficult when blocked by the wall
Solution Approach 1:
The latch is designed to operate in a rotational dimension rather than linear motion. The operation end can be rotated to different angular positions (locked, unlocked, intermediate) to achieve fixing and releasing functions. This rotational movement occurs in a different dimensional space that is not blocked by the wall, providing ease of operation while maintaining secure attachment
3Strength
If a hexagonal wrench is required to operate the set screw, then the frame can be securely fixed, but the operation becomes inconvenient when the wrench is not available
Solution Approach 1:
The fixing mechanism is designed to be self-servicing, allowing direct manual operation of the latch without requiring external tools like a hexagonal wrench. The latch can be easily manipulated by hand to lock and unlock the supporting frame, making the operation accessible and convenient while maintaining secure fixing through the latching mechanism
4Ease of operation
If a latch mechanism is introduced to enable tool-free operation, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The latch mechanism is localized to specific regions of the supporting frame structure. The latching end is positioned to engage with the bracket, while the operation end is accessible for manual manipulation. This localized design provides tool-free operation convenience while minimizing overall device complexity by concentrating the mechanism in specific areas rather than distributing it throughout the entire structure
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easy and efficient installation and disassembly of the supporting frame without tools, improving operational convenience and reducing interference from the wall.
Implementation Method 1
an elastic component disposed between the latch and the inner surface of the frame body and adapted to apply an elastic force to the latch for pushing the latch toward the locking position

AI summary
A supporting frame adapted to be attached to a bracket that is mounted on a wall is provided. The supporting frame includes a frame body, a latch, and an elastic component. The frame body includes an inner surface and an engaging portion that is disposed on the inner surface. The engaging portion is configured to detachably engage the bracket. The latch includes a latching end and an operation end. The operation end is operable to rotate the latch between a locking position where the latching end is adapted to abut against the bracket, and an unlocking position where the latching end is adapted to disengage from the bracket. The elastic component is disposed between the latch and the frame body and is adapted to apply an elastic force to the latch for pushing the latch toward the locking position.
