Threadless Outer Sleeve With Damping for Radial Tolerance Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection elements with damping functions face challenges in accessing threads from only one side and struggle to realize radial tolerance compensation, especially in scenarios with multiple connection points.
Innovation Solution
An outer sleeve of a connection element without a female thread, featuring an elastic outer body with a sleeve-like shaft, a fastening flange, and a hollow-cylindrical folding zone that forms a compression bead, allowing for radial tolerance compensation through the use of a spacer sleeve and a screw with a tolerance compensation disc.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the outer sleeve is arranged in the support part with the fastening part adjacent to the fastening flange, then the connection element can be installed from one side, but the thread must already be provided in the outer sleeve and radial tolerance compensation cannot be realized
Solution Approach 1:
The connection element is divided into separate functional components: the outer sleeve (arranged in the support part) and the fastening part (arranged in the attachment part). This segmentation allows the thread to be provided in the fastening part rather than the outer sleeve, simplifying the outer sleeve design while maintaining one-sided installation capability.
Solution Approach 2:
The patent introduces a tolerance compensation mechanism that acts as an intermediary between the outer sleeve and the fastening part. This mechanism enables radial tolerance compensation while preserving the one-sided accessibility advantage, resolving the contradiction between ease of operation and device complexity.
2Ease of operation
If the outer sleeve is arranged in the support part with the fastening part adjacent to the fastening flange, then the connection element can be installed from one side, but radial tolerance compensation cannot be realized
Solution Approach 1:
The patent introduces a dynamic tolerance compensation mechanism that can adapt radially during installation. This mechanism allows the connection element to adjust to radial tolerances while maintaining the one-sided installation advantage, resolving the contradiction between ease of operation and adaptability.
Solution Approach 2:
The tolerance compensation mechanism changes the radial parameters of the connection element during installation, allowing adaptation to radial tolerances. This parameter change capability is achieved without compromising the one-sided accessibility feature.
3Ease of operation
If a thread is provided in the outer sleeve for one-sided access, then accessibility is maintained, but radial tolerance compensation becomes difficult to realize
Solution Approach 1:
By segmenting the connection element into an outer sleeve and a separate fastening part, the thread can be provided in the fastening part rather than the outer sleeve. This segmentation allows the outer sleeve to focus on radial tolerance compensation while the fastening part handles the threading function.
Solution Approach 2:
A tolerance compensation mechanism serves as an intermediary between the outer sleeve and the fastening part, enabling radial tolerance adjustment without interfering with the thread accessibility maintained in the fastening part.
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
This solution facilitates easy assembly and radial tolerance compensation across multiple connection points, eliminating the need for long holes and enabling compensation in a plane rather than along a single axis, while maintaining accessibility from one side.
Implementation Method 1
an elastic outer body with a sleeve-like shaft, which comprises a fastening flange at a first axial end and, adjacent to a second axial end, a hollow-cylindrical folding zone which can be folded to form a compression bead

AI summary
A connection element without a female thread, having a damping function, and by which two components can be connected. The connection element has an outer sleeve, a spacer sleeve, and a screw having a first outer diameter and a tolerance compensation disc positioned on the screw. The outer sleeve has an outer body having a shaft with a fastening flange at a first end and, adjacent to a second end, a folding zone which can form a compression bead. The outer sleeve has a first inner diameter and a second inner diameter smaller than the first. A first component can be supported between the fastening flange and the compression bead. The second component can be fastened, adjacent to the second end of the outer sleeve, by the sleeve. The screw and the tolerance compensation disc are positioned in the outer sleeve with radial play.
