Damped Fastening Assembly for Tool-Free Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening arrangements lack a damping effect for both axial and radial vibrations and are costly to assemble and produce, often requiring tool-based assembly and being unsuitable for varying material thicknesses.
Innovation Solution
A fastening arrangement composed of two structurally identical units with central through-openings, each including a disc-shaped mounting element and damping element, where the damping element is partially arranged within the mounting element, providing a damping effect through compression and featuring a latching structure for secure engagement without the need for tools, suitable for different material thicknesses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fastening arrangements are used to secure components, then the components can be attached to one another, but the arrangement lacks damping effect for axial and radial vibrations
Solution Approach 1:
The damping element is nested within the mounting element, with the damping element being at least partially arranged in the central second through-opening of the mounting element. This nested configuration provides vibration damping functionality while maintaining a compact structure without requiring separate mounting and damping components.
Solution Approach 2:
The fastening arrangement combines a mounting element (typically rigid material) with a damping element (elastomeric or viscoelastic material) to create a composite structure. This composite design provides both structural support and vibration damping effects for axial and radial directions.
2Reliability
If two differently designed fastening devices are used to secure the fastening arrangement, then the fastening arrangement can be secured on both sides of the component opening, but the assembly and manufacturing effort increases
Solution Approach 1:
The fastening arrangement uses two identical fastening units with the same structure and design, rather than two differently designed devices. Each unit can be secured using the same method on both sides of the component opening, simplifying manufacturing and assembly processes while maintaining reliable securing.
Solution Approach 2:
The fastening arrangement is divided into two identical modular fastening units, each capable of independent installation. This segmentation into identical modules simplifies manufacturing by using standardized components and reduces assembly complexity through repetitive, uniform installation procedures.
3Reliability
If conventional fastening arrangements are used, then components can be attached, but tool-based assembly is required which increases complexity
Solution Approach 1:
The fastening units incorporate self-securing features through their locking structures that engage automatically when the fastening units are positioned on opposite sides of the component opening. The identical locking structures of the two fastening units secure to each other without requiring external tools, enabling tool-free assembly while maintaining reliable component attachment.
4Adaptability or versatility
If conventional fastening arrangements are used, then components can be fastened, but they are unsuitable for varying material thicknesses
Solution Approach 1:
The damping element provides dynamic adaptation to varying material thicknesses through its elastomeric or viscoelastic properties. When the fastening units are secured, the damping element compresses between the mounting elements, automatically adjusting to different thickness variations in the component opening while maintaining secure fastening through the rigid mounting elements and locking structures.

AI summary
The invention relates to a fastening arrangement (1; 60) with damping effect, consisting of two structurally identical fastening units (3; 63; 103) each having a central first through opening (5; 105). Each fastening unit (3; 63; 103) comprises a mounting element (10; 110) and a damping element (30; 130). The mounting element (10; 110) is disc-shaped with a central second through opening (12) and an identical detent structure extends from a first side (14; 114) of each mounting element (10; 110). The damping element (30; 130) is disc-shaped with a central third through opening (32) and is arranged at last partially in the central second through opening (12) of the mounting element (10; 110). Due to this construction the two fastening units (3; 103) can be fastened to one another by means of the mutually facing first sides (14; 114) having the identical detent structure of the respective mounting elements (10; 110) with first component (A) arranged between them.
