Anti-vibration Clamp With Elastic Interlayer For Pipe Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-vibration clamps for pipes in automotive applications face challenges in achieving high joining strength between structural parts without using complex molds or assembly tools, and in preventing vibration transmission between pipes and car body components.
Innovation Solution
The solution involves molding a pipe holding component and a clamp body from hard resin, with an elastic connecting component made from soft resin placed between them, featuring specific geometrical features like holding ribs and curved portions to prevent slipping and vibration transmission, and allowing for easy assembly without specialized tools.

Engineering Contradiction Analysis
1Object-affected harmful factors
If an elastic connecting component is placed between the pipe holding component and the clamp body to absorb vibration, then the anti-vibration performance is improved, but the joining strength between components deteriorates
Solution Approach 1:
The elastic connecting component is inserted into a hollow cylindrical portion of the pipe holding component, creating a nested structure. The locking protrusions on the elastic component engage with locking grooves on the pipe holding component, forming an integrated assembly that maintains high joining strength while preserving vibration absorption capabilities.
Solution Approach 2:
The elastic connecting component serves as an intermediary element between the pipe holding component and the clamp body. It mediates the connection by providing both mechanical attachment (through locking features) and vibration isolation (through elastic deformation), resolving the contradiction between strength and vibration absorption.
2Manufacturing precision
If insert molding is used to form the elastic connecting component between metal molds, then the manufacturing precision is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The pipe holding component is first molded with an integrated hollow cylindrical portion and locking grooves. The elastic connecting component is then simply inserted into this pre-formed structure and locked in place, eliminating the need for complex insert molding operations and metallic molds while maintaining precise positioning.
Solution Approach 2:
The clamp is divided into separable components: the pipe holding component, the elastic connecting component, and the clamp body. This segmentation allows each part to be manufactured independently using simple molding processes, then assembled through straightforward insertion and locking, reducing overall device complexity.

AI summary
An anti-vibration clamp for holding pipes includes a pipe holding component which further includes pipe holders for locking the pipes; a clamp body including a stud locking portion for locking to a stud, and a floating attachment portion for holding the pipe holding component; and an elastic connecting component made of soft resin placed between the pipe holding component and the clamp body so that the pipe holding component and the clamp body do not contact one another directly. The pipe holding component, the elastic connecting component and the clamp body are held so that it is difficult for them to each slip mutually.
