Split-Nut Threaded Rod Coupler for Fast Structural Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing structural fasteners lack an efficient mechanism to securely attach threaded rods to load-bearing structural components while allowing for easy axial sliding and secure threadable engagement, which is crucial for suspending non-structural components in building structures.
Innovation Solution
A structural fastener system comprising a structure coupler and a threaded rod coupler with a split nut that can transition between open and closed positions, allowing axial sliding and threadable engagement of the threaded rod, utilizing a beam clamp and a locking mechanism to ensure secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional structural fastener uses a fixed nut or coupling mechanism, then the attachment is secure and stable, but the installation process is time-consuming and requires precise alignment
Solution Approach 1:
The split nut is designed to be dynamically adjustable between open and closed positions. In the open position, the threaded rod can be easily inserted without precise alignment. Once inserted, the split nut closes to engage the threads securely. This dynamic transformation allows the fastener to provide both easy installation and secure attachment.
Solution Approach 2:
The nut is divided into two separate halves that can move independently relative to each other. This segmentation allows one half to remain stationary while the other moves to open or close the split, enabling easy rod insertion while maintaining secure engagement when closed.
2Adaptability or versatility
If a structural fastener allows easy sliding and adjustment of the threaded rod, then the installation is quick and adaptable, but the secure engagement and stability are compromised
Solution Approach 1:
The split nut provides dynamic adaptability by allowing the threaded rod to be inserted and adjusted when in the open position. Once the desired position is achieved, the split nut closes to provide secure engagement. This dynamic state change enables both adjustability and strength.
Solution Approach 2:
The fastener system changes its mechanical parameters from a loose, adjustable state (open split nut) to a tight, secure state (closed split nut). This parameter change allows the system to provide both adaptability during installation and secure engagement during operation.
3Reliability
If a structural fastener uses a complex locking mechanism to ensure secure attachment, then the reliability is improved, but the device complexity and number of parts increase
Solution Approach 1:
The nut is segmented into two halves that function as a simple locking mechanism. The split design itself provides the locking function through the engagement of the two halves with the threaded rod, eliminating the need for additional complex locking components while maintaining security of attachment.
Solution Approach 2:
The split nut structure is self-locking through its design. When closed, the two halves engage the threaded rod and maintain their position through the geometry of the split and the threading action, providing secure attachment without requiring external locking mechanisms or additional parts.
