Elastic Tubular Damper Coupling for Secure Vibration Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-vibration bush designs for electronic devices often fail to secure a strong holding force, leading to inadequate protection against stress and vibration, and complicate the coupling process.
Innovation Solution
A damper with a tubular body that is elastically deformable between two forms, allowing easy insertion into a holding hole in its smaller form and securing the holding force by expanding to match the hole's size, coupled with a method involving heat to melt adhesive and deform the damper, simplifying the coupling process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the damper is designed with a fixed outer shape larger than the holding hole to secure holding force, then the holding force is improved, but the insertion process becomes difficult
Solution Approach 1:
The damper incorporates an elastically deformable tubular body that can dynamically change its outer diameter. During insertion, the tubular body is compressed to reduce its diameter for easy insertion into the holding hole. Once inserted, the tubular body elastically recovers to its original larger diameter to secure strong holding force against the holding hole inner surface.
Solution Approach 2:
The patent applies parameter changes by transforming the dimensional parameter of the tubular body's outer diameter from a small value (during insertion) to a large value (during operation). This is achieved through elastic deformation controlled by compression force during assembly, allowing the same component to satisfy both insertion and holding requirements at different stages.
2Ease of operation
If the damper outer shape is reduced to facilitate insertion, then the insertion process is simplified, but the holding force becomes insufficient
Solution Approach 1:
The damper incorporates an elastically deformable tubular body that can dynamically change its outer diameter. During insertion, the tubular body is compressed to reduce its diameter for easy insertion into the holding hole. Once inserted, the tubular body elastically recovers to its original larger diameter to secure strong holding force against the holding hole inner surface.
Solution Approach 2:

This is achieved through elastic deformation controlled by compression force during assembly, allowing the same component to satisfy both insertion and holding requirements at different stages.
3Strength
If a complex coupling process is used to secure holding force, then the holding force is improved, but the coupling process becomes complicated
Solution Approach 1:
The damper utilizes the self-service principle through the elastic recovery of the tubular body. After insertion, the tubular body automatically recovers its original shape and exerts radial outward force against the holding hole inner surface without requiring additional fastening operations, locking mechanisms, or external tightening forces, thereby simplifying the coupling process while securing strong holding force.
Solution Approach 2:
The patent extracts the complex coupling mechanisms (such as threads, clips, or additional fasteners) from the assembly process and replaces them with the elastic recovery mechanism of the tubular body alone, which inherently provides both insertion facilitation and holding force generation through its shape memory and elastic properties.
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
The damper effectively secures the holding force, protecting the electronic device from stress and vibration while simplifying the coupling process by ensuring proper fit and pressure against the holding hole.
Implementation Method 1
The tubular body is elastically deformable between a first form and a second form. The tubular body in the first form has an outer shape that is smaller than the holding hole. The tubular body in the second form has an outer shape that is equal to or greater than the holding hole.
Implementation Method 2
a deforming step of melting the adhesive with heat to deform the tubular body from the first form to the second form
Implementation Method 3
The tubular body is pressed against an inner surface of the holding hole by restoring force
