Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for decoupling and attaching plate-like components, particularly heat shielding parts, lack a simple, easy-to-assemble fastening device that provides effective damping and displaceability without excessive tooling, and often result in surface damage or noise during movement.
Innovation Solution
A fastening device with a rigid sleeve surrounded by a knitted wire mesh damping body, designed to fit through a plate-like component with specific dimensions allowing for decoupling and damping in both axial and radial directions, using a sliding disk to prevent surface contact and ensure constant displacement force, and adjustable for different thicknesses and requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid fastening device is used to securely attach the plate-like component, then the attachment reliability is improved, but the damping effect and displaceability are reduced
Solution Approach 1:
The fastening device combines a rigid sleeve (metal) with a flexible wire mesh damping body, creating a composite structure that simultaneously provides secure attachment through the rigid component and vibration damping through the flexible mesh component. This composite approach resolves the contradiction by integrating two materials with complementary properties into a single functional assembly.
Solution Approach 2:
The wire mesh damping body is nested within or around the rigid sleeve structure, with the mesh positioned to contact the plate-like component while the sleeve provides the primary fastening function. This nested arrangement allows the inner damping element to provide vibration absorption while the outer rigid element ensures secure attachment, enabling both functions to operate simultaneously without interference.
2Adaptability or versatility
If the fastening device is designed to be displaceable within the mounting opening, then the adaptability is improved, but the attachment stability is reduced
Solution Approach 1:
The fastening device is designed with dynamic characteristics, allowing the wire mesh damping body to move and deform within the mounting opening while maintaining attachment stability. The mesh structure can adapt its position and configuration in response to vibrations and displacements, providing continuous damping effectiveness across different positions and operational conditions.
3Ease of manufacture
If a simple fastening device design is used, then the ease of manufacture is improved, but the damping effectiveness is reduced
Solution Approach 1:
The wire mesh damping body utilizes a porous, open-work structure that provides effective vibration damping while maintaining simplicity in manufacture. The mesh can be produced using standard wire drawing and meshing techniques, avoiding complex machining or assembly processes. The porous structure inherently provides damping through friction and deformation of the wire elements, achieving effective damping with a manufacturally simple component.

Implementation Method 1
clamping and/or frictional forces between the wire mesh and the plate-like component must be overcome
Implementation Method 2
