Coupling assembly and bracket device thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing slide rail tool-free mounting frame lacks a mechanism to prevent arbitrary displacement of the hooks, which compromises the secure fastening of the bracket device to a post.
Innovation Solution
A coupling assembly with a bracket device that includes a fastening member and a fitting, where the fastening member can be displaced between an unlocked and locked position, and the fitting at a predetermined position prevents the fastening member from transitioning from unlocked to locked, while its absence allows displacement from unlocked to locked to secure the bracket to a post.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fastening member is made movable between unlocked and locked positions for rapid mounting/dismounting, then the ease of operation is improved, but the stability and security of fastening deteriorates due to arbitrary displacement
Solution Approach 1:
The fitting acts as an intermediary component that mediates between the movable fastening member and the bracket body. When engaged at the predetermined position, it temporarily restrains the fastening member to prevent arbitrary displacement while allowing controlled movement for mounting/dismounting operations.
Solution Approach 2:
The fastening member is designed with dynamic characteristics, being movable between unlocked and locked positions. This dynamic design enables rapid mounting and dismounting operations while the fitting provides conditional stabilization when engaged, resolving the contradiction between mobility and stability.
2Stability of the object's composition
If the fitting is added to prevent arbitrary displacement of the fastening member, then the stability is improved, but the device complexity increases
Solution Approach 1:
The fitting serves multiple functions: it acts as a restraining element to prevent arbitrary displacement, provides a predetermined position reference, and enables controlled movement when disengaged. The supporting frame also serves dual purposes as both structural support and a mechanism to guide fastening member movement, reducing the need for separate components.
Solution Approach 2:
The fitting and supporting frame are integrated into the bracket structure, combining the stabilization function with the existing structural elements. The supporting frame merges the support function with the guidance mechanism for the fastening member, reducing overall component count and complexity.
3Manufacturing precision
If the fitting is positioned at a predetermined location to control fastening member movement, then the manufacturing precision is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The fitting is pre-positioned at the predetermined location on the bracket body during manufacturing, establishing the reference point for fastening member control before assembly. The supporting frame is also pre-assembled with the bracket, reducing on-site assembly complexity while maintaining precise positioning requirements.

AI summary
A bracket device (14) includes a bracket (24), a fastening member (26), a supporting frame (20), and a fitting (28). The fastening member (26) is movable with respect to the bracket (24). Once the supporting frame (20) is operated and thus displaced with respect to the bracket (24) to a first position (PI), the fastening member (26) is supported by the supporting frame (20) and hence in a particular position (LI). Once the supporting frame (20) is operated and thus displaced with respect to the bracket (24) to a second position (P2), the fastening member (26) is not supported by the supporting frame (20) and therefore no longer in the particular position (LI). When the fitting (28) is at a predetermined position (F), the supporting frame (20) is prevented from displacement from the first position (PI) to the second position (P2).
