Profiled Clamp Clip Structure for Rotation-Free Premounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Profiled clamps in a premounted state can rotate freely, making the final mounting process more difficult due to the need for initial orientation.
Innovation Solution
A clip element with a fastening portion is integrated into the clamp band, allowing for releasable fixation in a positionally fixed manner, preventing rotation during premounting and final mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the profiled clamp is designed to be rotatable during premounting for ease of installation, then the mounting process becomes more flexible, but the clamp cannot maintain a fixed orientation which complicates the final mounting
Solution Approach 1:
The clamp band is designed with dynamic characteristics allowing it to be easily installed by slipping over flanges when loose, then transitions to a fixed state when tensioned. The clip element similarly transitions from a movable installation aid to a fixed positional marker, enabling easy installation followed by stable final mounting.
Solution Approach 2:
The clip element is pre-attached to the clamp band during manufacturing, serving as a preliminary orientation marker. This preliminary action of attaching the clip element allows the installer to quickly orient and position the clamp before final tightening, reducing the complexity of the final mounting step.
2Productivity
If a clip element is added to prevent rotation during premounting, then the mounting process is simplified, but the device complexity increases
Solution Approach 1:
The clip element is merged with the clamp band through permanent attachment during manufacturing. This combining of the orientation marker function with the existing clamp band structure achieves the rotation prevention benefit without adding a separate, complex assembly step during installation.
Solution Approach 2:
The clip element is designed as a simple, inexpensive component that can be easily attached to the clamp band. Its simple geometry and low cost mean that even if it needs to be replaced or adjusted, the impact on overall system cost is minimal, making it an economical solution for improving mounting efficiency.

AI summary
The disclosure relates to a profiled clamp having a clamp band, which extends in a peripheral direction about a longitudinal axis between a first clamping head and a second clamping head, the clamp band having a clip element. The clip element has a fastening portion, which fastens the clip element to the clamp band such that the clip element is stationary at least in the peripheral direction, and a protrusion portion, which extends away from the clamp band up to a free end piece. Thus, a profiled clamp for which rotation is avoided simply and economically in the premounted stated is provided.
