Solution Overview

Problem

Vibrations from uneven road surfaces are not effectively absorbed by typical mounts for in-vehicle computers or servers, leading to potential damage from transmitted vibrations.

Innovation Solution

A supporting assembly that includes a plate body, a cushioning component, and a fastener, where the cushioning component is compressed between the casing of the electronic device and the fastener to absorb vibrations, thereby mitigating their transfer to the device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a typical mount is used to fix the electronic device, then the device can be secured to the chassis, but the vibrations from uneven road surfaces are not effectively absorbed and are transmitted to the device

Engineering Contradiction:

Improveprotection against vibration damageVSAvoidvibration transmission

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The cushioning component serves as an intermediary element between the electronic device and the mounting system. It is disposed through the mounting hole and compressed by the fastener and chassis, creating a vibration-absorbing layer that mediates the force transmission path and reduces harmful vibrations reaching the device

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The cushioning component is pre-installed through the mounting hole before the fastener is fully tightened. This beforehand cushioning arrangement ensures that the vibration-absorbing element is already in place to mitigate shocks and vibrations before they can damage the electronic device during operation

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

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 supporting assembly effectively reduces vibrations transferred to the electronic device, as demonstrated by reduced peak values and acceleration loads in vibration tests, ensuring better protection against vibration damage.

Implementation Method 1

the cushioning component can effectively absorb the vibrations transferred to the fastener from the casing of the electronic device

Methodology Applied

Scientific EffectVibration absorption: Damping

Implementation Method 2

the cushioning component is compressed by another side of the fastener and the chassis

Methodology Applied

Scientific EffectCompression: Compression
