Spherical Hanging Joint for Horizontal Shelf Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hanging mechanisms for storage shelves can become tilted when the ceiling is not horizontal or when the frame is improperly fixed, leading to the shelf module not being hung horizontally.
Innovation Solution
A hanging mechanism comprising a first hanging member, a second hanging member, and a connecting section with a protruding curved surface and a recessed curved surface, allowing the second hanging member to remain vertical even if the first hanging member is tilted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hanging frame is directly fixed to a tilted ceiling or improperly fixed, then the hanging frame becomes tilted with respect to a horizontal plane, but the shelf module cannot be hung horizontally
Solution Approach 1:
The connecting section employs a spherical interface where the first hanging member has a spherical outer surface and the second hanging member has a corresponding spherical inner surface. This curved surface design allows automatic self-leveling through rotational adjustment, enabling the shelf module to hang horizontally even when the ceiling is tilted or the fixing position is not perfectly horizontal.
2Stability of the object's composition
If the ceiling is tilted or the hanging frame is improperly fixed, then the hanging frame tilts, but the structure becomes unstable with lateral oscillation
Solution Approach 1:
The spherical connecting surfaces enable the hanging members to rotate and self-align, converting lateral instability into rotational adjustment. The spherical geometry provides a stable equilibrium position where the center of gravity aligns vertically with the support point, eliminating lateral oscillation while maintaining structural stability.

AI summary
In order to facilitate horizontally hanging an object, a hanging mechanism includes: a first hanging shaft to be hung from a ceiling; a second hanging shaft supported so as to be hung from the first hanging shaft; and a connecting section connecting the first hanging shaft and the second hanging shaft. The connecting section includes: a protruding spherical surface of a first connecting member that is provided on the first hanging shaft side; and a recessed surface portion, which is a recessed spherical surface of a second connecting member that is provided on the second hanging shaft side and that is in contact with the spherical surface of the first connecting member.
