Profile Clamp Transition Geometry for Easier Flange Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing profile clamps are complicated to install due to the need to guide the clamping head completely open to the flanges and then reassemble and tighten it, which increases the installation complexity.
Innovation Solution
A profile clamp design featuring a clamp band with a first transition section and a radially projecting clamping element, where the width of the base increases uniformly toward the clamping element, allowing for easier insertion of flanges and potentially eliminating the need for complete disassembly of the clamping head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the profile clamp uses a traditional clamp band design with uniform cross section, then the manufacturing process is simple, but the installation complexity increases due to the need to guide the clamping head completely open and reassemble it
Solution Approach 1:
The clamp band is segmented into different functional sections: a clamp section with uniform cross-section for manufacturing simplicity, and a first transition section with varying base width that tapers toward the clamping element. This segmentation allows each part to serve its specific function - the uniform section is easy to manufacture while the transition section enables easier flange insertion during installation.
Solution Approach 2:
The profile clamp applies local quality by giving different geometric characteristics to different parts of the clamp band. The clamp section maintains a uniform profile for manufacturing ease, while the first transition section features a varying base width that increases toward the clamping element, creating a tapered geometry that facilitates flange insertion without requiring complete disassembly of the clamping head.
2Strength
If the base width of the profile cross section is uniform throughout the clamp band, then the structural integrity is maintained, but the ease of inserting flanges into the profile clamp is reduced
Solution Approach 1:
The profile clamp implements local quality by creating a first transition section where the base width varies specifically in the region needed for flange insertion. This localized geometric variation provides a tapered guide that facilitates easier insertion, while the clamp section maintains uniform dimensions to preserve structural integrity and load-bearing capacity.
Solution Approach 2:
The invention addresses the insertion difficulty by introducing a dimensional variation in the base width of the profile cross-section. The first transition section features a base width that changes along the longitudinal axis, creating a tapered geometry that guides flanges into position more easily, while the overall structural dimensions remain sufficient to maintain integrity.
3Force
If the profile clamp design requires complete disassembly of the clamping head for installation, then the clamping force can be maximized, but the installation time and labor increase
Solution Approach 1:
The clamp band is segmented into functional sections, with the first transition section designed to accept flanges during installation. This segmentation allows the clamping head to remain assembled during the insertion process, eliminating the need for complete disassembly and subsequent reassembly, thereby reducing installation time while preserving the ability to apply maximum clamping force.
Solution Approach 2:
The first transition section is pre-formed with a varying base width that creates a tapered geometry. This preliminary geometric preparation facilitates the insertion of flanges before the clamping head is tightened, allowing installation to proceed without complete disassembly and reducing the overall installation time and labor requirements.

AI summary
The disclosure relates to a profile clamp for connecting two tubular bodies wherein: the profile clamp has a clamp band having a profile cross-section that is open on the radially inner side; the clamp band, at at least one end, has a first transition portion and an adjoining, radially protruding clamping portion; and the clamping element can be clamped in the circumferential direction in order to tighten the profile clamp. A width of a base of the profile cross-section evenly increases from the end of the first transition portion facing away from the clamping element to the clamping element.
