Threaded Rod Hanger With Adjustable Receiver and Vibration Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved devices that can quickly and easily attach threaded rods to overhead structures, such as those used to support fire sprinkler pipes, without requiring complex installation processes.
Innovation Solution
A threaded rod hanger system comprising a connector and a threaded rod receiver, which allows for quick and easy attachment to overhead structures, featuring components that securely engage the structure and enable easy adjustment of the threaded rod's height, using mechanisms like self-drilling and tapping fasteners to ensure a zero-clearance fit and prevent loosening over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional threaded rod hangers are used, then the installation process is simple, but the installation time is excessive and efficiency is low
Solution Approach 1:
The hanger device is divided into separate modular components including a hanger body, threaded rod receiver, and fastening mechanism. This segmentation allows for pre-assembly of components and rapid installation by simply connecting the modular parts together without requiring complex on-site assembly procedures.
Solution Approach 2:
The threaded rod receiver is pre-threaded with internal threads during manufacturing, eliminating the need for on-site threading operations. The hanger body is pre-configured with attachment features that allow for quick mounting to overhead structures, significantly reducing installation time and improving productivity.
2Reliability
If standard fasteners are used, then the assembly is easy to install, but the fasteners loosen over time due to vibration
Solution Approach 1:
The fastening mechanism incorporates a dynamic locking feature where the threaded rod receiver is designed to self-tighten under vibrational loads. The internal threads are configured with a slight angle that causes the receiver to progressively tighten against the threaded rod during vibration, converting harmful vibrations into a tightening force that enhances reliability without complicating installation.
3Adaptability or versatility
If adjustable height features are added, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The threaded rod receiver is nested within the hanger body, with the receiver featuring internal threading that allows the threaded rod to be inserted and adjusted in height. The nested configuration allows for height adjustment functionality to be achieved through the interaction of simple geometric features rather than complex mechanical adjustment mechanisms, maintaining ease of operation while providing versatility.
