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 mechanism that allows for tool-free installation and removal by rotating a latch between locking and unlocking positions using an elastic component to facilitate secure attachment and detachment from a bracket.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a set screw is used to secure the supporting frame to the fixing bracket, then the supporting frame can be firmly fixed, but the installation and removal require a hexagonal wrench which is inconvenient and time-consuming

Engineering Contradiction:
Improvefixing reliabilityVSAvoidinstallation convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The supporting frame is designed with a self-locking structure where the frame body itself forms a locking mechanism with the fixing bracket. The inclined surface and positioning structure enable the frame to automatically lock into place without requiring external fasteners or tools, allowing users to install and remove the frame by hand.

Inventive Principle:
Principle #25Self-service

2Reliability

If a set screw is used to secure the supporting frame, then the connection is secure, but the operation is easily blocked by the wall and difficult to perform

Engineering Contradiction:
Improveconnection reliabilityVSAvoidoperational accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The locking mechanism is extracted from the traditional set screw design and integrated directly into the supporting frame body. The locking structure is positioned on the outer surface of the frame, away from the wall, allowing users to operate it without obstruction from the wall surface.

Inventive Principle:
Principle #2Taking out (Extraction)

3Strength

If a hexagonal wrench is required to operate the set screw, then the connection can be tightened securely, but the operation becomes time-consuming

Engineering Contradiction:
Improvefastening strengthVSAvoidinstallation time
Core Design Contradiction:
StrengthVSLoss of time

Solution Approach 1:

The frame body incorporates a self-locking mechanism that achieves secure fastening through its geometric structure (inclined surface and positioning features) without requiring external tools. Users can install or remove the supporting frame by hand in seconds, eliminating the time required to locate and operate a hexagonal wrench.

Inventive Principle:
Principle #25Self-service

AI summary

A supporting frame adapted to be attached to a bracket (2) that is mounted on a wall (1) is provided. The supporting frame includes a frame body (4), a latch (6), and an elastic component (7). The frame body (4) includes an inner surface (41) and an engaging portion (43). The engaging portion (43) is configured to detachably engage the bracket (2). The latch (6) includes a latching end (61) and an operation end (62). The operation end (62) is operable to rotate the latch (6) between a locking position, and an unlocking position. The elastic component (7) is disposed between the latch (6) and the frame body (4) and is adapted to apply an elastic force to the latch (6) for pushing the latch (6) toward the locking position.
