Threaded Rod Support Bracket With Detent Locking for Fast Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional supports for threaded rods, such as trapeze hangers and suspension rings, are time-consuming and fiddly to install, especially at heights, requiring manual positioning of nuts and often involving complex configurations that complicate the installation of multiple levels and directional adjustments of ducts and cable trays.
Innovation Solution
A support structure with a bracket formed from a single folded sheet of metallic or polymeric material, featuring aligned apertures for the threaded rod, detent elements, and a pressure element with biasing means to securely attach to threaded rods, allowing for easy alignment and locking without the need for manual nut positioning, and enabling quick attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional trapeze hangers with nuts are used to support cable trays and ducts, then the support structure can be securely attached to threaded rods, but the installation process becomes time-consuming and fiddly, especially when working at height
Solution Approach 1:
The bracket is divided into distinct functional segments: attachment portion with apertures for rod insertion, detent elements for threading engagement, pressure element for clamping force, and support portion for loading. This segmentation allows each element to perform its specific function efficiently, reducing overall installation complexity and time while maintaining secure attachment
Solution Approach 2:
The detent elements automatically engage with the threads of the rod when the rod is inserted through the apertures, eliminating the need for manual nut positioning. The pressure element with biasing means automatically applies clamping force to secure the bracket to the rod, providing self-securing functionality that reduces installation time and effort
2Adaptability or versatility
If multiple nuts are positioned manually on threaded rods to install hangers at multiple levels, then the support structure can accommodate multiple levels of cable trays and ducts, but the complexity of the installation process increases significantly
Solution Approach 1:
The bracket design with its aligned apertures and detent elements can be universally applied at multiple levels along the threaded rod without requiring different components or complex positioning procedures. The same bracket type serves multiple functions across different installation levels, simplifying the overall system complexity while maintaining adaptability
3Adaptability or versatility
If suspension rings are rotated to engage with threaded rods for supporting ventilation ducts, then the ducts can be secured in various directions, but the installation process becomes more complex and time-consuming
Solution Approach 1:
Instead of rotating the support component to engage with the rod, the design inverts the approach by having the rod pass through aligned apertures in the bracket, with detent elements that automatically engage the rod's threads. This inversion eliminates the need for rotational manipulation, significantly improving ease of installation while maintaining the ability to support ducts in various directions through the bracket's geometry
