Electronic Apparatus Module Cushioning for Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic apparatuses face challenges in withstanding impact and vibration, leading to reliability issues due to the direct transmission of kinetic energy to sensitive modules, which can cause damage and reduce the overall reliability of the devices.
Innovation Solution
Incorporating a first cushion and a holding member that allows the module to move within a first case, absorbing impact and vibration energy, thereby preventing direct transmission to the module, and utilizing a second cushion for additional impact absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the module is directly fixed in the first case, then the structural stability is improved, but the impact and vibration are directly transmitted to the module, reducing reliability
Solution Approach 1:
A first cushion is introduced as an intermediary component between the first case and the module. This cushion absorbs and attenuates impact and vibration energy, preventing direct transmission to the module while maintaining structural stability. The holding member serves as another intermediary that provides flexible retention rather than rigid fixation.
Solution Approach 2:
The first cushion is pre-installed between the first case and the module to provide advance protection against impact and vibration. This cushioning arrangement is prepared in advance to absorb shock energy before it reaches the module, thereby improving reliability without compromising structural integrity.
2Reliability
If a cushion is added between the first case and the module, then the impact absorption is improved, but the device complexity increases
Solution Approach 1:
The first cushion is implemented as a flexible component that can be easily integrated into the existing structure. This flexible element provides effective impact absorption without requiring complex mechanical structures, thereby improving reliability while minimizing increases in device complexity.
Solution Approach 2:
The cushioning function is achieved through a simple pre-installed first cushion rather than complex active protection systems. This straightforward approach absorbs impact energy effectively while keeping the overall device structure relatively simple and easy to manufacture.
