Reinforcing Vibration-Damping Material That Prevents Downward Shift
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration-damping reinforcing materials do not adequately achieve both reinforcement performance and vibration-damping performance, and they often experience downward displacement when attached to objects.
Innovation Solution
A reinforcing vibration-damping material comprising a reinforcing material and a vibration-damping material, where the vibration-damping material has a first portion overlapping the reinforcing material and a second portion not overlapping, which protrudes beyond the edge of the reinforcing material to adhere directly to the object, thereby suppressing downward displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a vibration-damping reinforcing material is attached to an object, then reinforcement performance is improved, but downward displacement occurs causing misplacement
Solution Approach 1:
The vibration-damping material is divided into two distinct portions: a first portion that overlaps with the reinforcing material and a second portion that protrudes beyond the reinforcing material's edge. This segmentation allows the second portion to adhere directly to the object and prevent downward displacement, while the first portion maintains vibration-damping functionality.
Solution Approach 2:
The second portion of the vibration-damping material acts as an intermediary element between the reinforcing material and the object. It provides additional adhesion to the object, serving as a mediator that prevents the reinforcing material from displacing downward while allowing the first portion to maintain contact with the reinforcing material for vibration damping.
2Reliability
If vibration-damping material is placed only on reinforcing material, then vibration-damping performance is achieved, but adherence to object is insufficient
Solution Approach 1:
The vibration-damping material extends beyond the reinforcing material in a lateral dimension, creating a second portion that contacts the object directly. This dimensional extension allows the vibration-damping material to participate in both vibration damping (through the first portion) and adhesion (through the second portion), resolving the contradiction between these two functions.
3Strength
If reinforcing material alone is used, then reinforcement is achieved, but vibration-damping performance is insufficient
Solution Approach 1:
The patent merges the reinforcing material and vibration-damping material into a single integrated structure where the vibration-damping material is disposed on the reinforcing material. The first portion of the vibration-damping material overlaps with the reinforcing material, combining both reinforcement and vibration-damping functions in one composite structure.

AI summary
A reinforcing vibration-damping material that includes a reinforcing material and a vibration-damping material disposed on the reinforcing material in a thickness direction of the reinforcing material. The vibration-damping material has a first portion that overlaps the reinforcing material in the thickness direction and a second portion that does not overlap the reinforcing material in the thickness direction. When the reinforcing vibration-damping material is attached to the object, the reinforcing material is adhered to the object and the second portion of the vibration-damping material is also adhered to the object so that the vibration-damping material suppresses the downward displacement of the reinforcing material.
