Crimping Element with Mobile Nut for Axial Radial Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixing devices struggle with insufficient radial movement and complex assembly processes, particularly in aligning screws with misaligned holes, and require precise deformation for proper function.
Innovation Solution
A fixing device with a crimping element and nut configuration allowing both axial and radial movement, featuring an insert with a helical thread and a fusible zone for deformation during crimping, enabling better angular adjustment and simplified assembly without deformation of the nut.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the attachment element is formed by deformation of the second shaft after introduction into the first shaft, then radial movement is allowed, but the device becomes difficult to produce and assembly is complex
Solution Approach 1:
The device is divided into separate components: the first shaft, the second shaft with attachment element, and the insert. These components can be manufactured independently and assembled in a simplified sequence, avoiding the need for post-assembly deformation operations.
Solution Approach 2:
The attachment element is pre-formed on the second shaft before assembly, and the insert is pre-positioned in the first shaft. This preliminary preparation eliminates the need for complex deformation operations after the shafts are assembled together.
2Adaptability or versatility
If the insert penetrates into the first shaft to allow radial displacement, then radial movement is enhanced, but the structural integrity may be compromised
Solution Approach 1:
The insert is nested within the first shaft, and the attachment element is nested within the insert. This nested configuration allows the components to move relative to each other while maintaining a compact structure and preserving the overall structural integrity of the assembly.

AI summary
The device (1) has a hooking element (7) arranged with a first shaft (3) of a crimping element (2) so as to form an axial abutment permitting axial displacement of a second shaft (5) of a nut (4) with respect to the first shaft, while limiting the axial displacement of the second shaft. An insert (9) is screwed into a thread of the second shaft. The insert penetrates into a section of the first shaft having inner diameter greater than outer diameter of the insert so as to allow radial displacement of the second shaft with respect to the first shaft and to form a radial abutment. The insert is a helical thread. An independent claim is also included for a method for assembling a fixation device.
