Threaded Rod Clamp Joining Different Diameters and Thread Pitches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing threaded rod connectors require precise alignment and are not suitable for joining rods of different diameters or thread pitches, making them difficult to use and inspect, especially for providing full strength connections.
Innovation Solution
A clamp apparatus that compresses overlapping threaded portions of rods, allowing for easy alignment and connection of rods with the same or different diameters and thread pitches, using a body with a U-shape and fasteners to inhibit relative motion between the rods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If threaded rod connectors are used to join rods, then rods can be connected, but precise alignment is required and rods of different diameters or thread pitches cannot be joined
Solution Approach 1:
The clamp is designed with a universal structure that can accommodate rods of different diameters and thread pitches. The clamp body includes a U-shaped opening that can receive various rod configurations, and the fastening mechanism applies compression force regardless of the specific rod dimensions, enabling one device to perform multiple joining functions.
Solution Approach 2:
The clamp transforms the joining mechanism from thread-matching (which requires precise parameter matching) to compression-based joining. By changing from a threaded connection paradigm to a compressed clamping paradigm, the device can accommodate varying rod parameters without requiring precise alignment or matching thread specifications.
2Reliability
If threaded rod connectors are used, then rod connection is achieved, but it is difficult to determine if full connection strength is obtained
Solution Approach 1:
The clamp provides self-evident installation verification through its design features. The visible compression force applied by the fastener, the clamping action on the rod surfaces, and the physical deformation of the clamp body around the rods all provide immediate visual confirmation that the connection is properly secured, eliminating the need for complex inspection procedures.
3Stability of the object's composition
If a single continuous threaded rod is used, then structural stability is provided, but it cannot be easily inspected or aligned
Solution Approach 1:
The clamp divides the continuous rod structure into separable segments that can be independently positioned and aligned. By using discrete clamp units that can be attached at different locations, the system maintains structural stability through multiple connection points while allowing easy alignment and inspection of each individual clamp-rod assembly.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The clamp apparatus provides efficient resistance to tension and compression loads, offering greater structural stability than a single continuous threaded rod and allowing for easy inspection and alignment, making it compatible with current rod uses.
Implementation Method 1
the fastener is tightened, the apparatus imparts a force that compresses the first rod and the second rod, such that the force inhibits relative motion between the accepted first rod and the accepted second rod

AI summary
A clamp for joining rods and a method for joining rods used for bracing a load is presented. The clamp has an opening to accept threaded portions of each of a pair of rods, which are parallel to each other with threads touching. The clamp forces the thread portions of the rods together to allow the rods to support compressive and tensile loads. The clamps may be used in pairs to provide added bending resistance to the rods.
