Copper Foil Core Support Damping for Transport Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Copper foil defects occur during transportation due to vibrations and shaking, which existing accommodation apparatuses fail to adequately mitigate, leading to reduced quality and increased transportation challenges.
Innovation Solution
An apparatus with independent support and damper portions is designed to absorb vibrations and shaking, featuring a combination of support grooves, reduction grooves, and elastically deformable damper bodies with protrusions to securely hold the core and reduce transferred shocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If copper foil is transported using a conventional accommodation apparatus that supports the core protruding from both sides, then the apparatus structure is simple, but vibrations and shaking during transportation are transferred to the core and copper foil, causing defects
Solution Approach 1:
The patent applies beforehand cushioning by incorporating damper portions between the support portions and the core before transportation occurs. These dampers are pre-installed to cushion against vibrations and shaking that will occur during transport, preventing defects in the copper foil before they can happen rather than addressing them after
Solution Approach 2:
The damper portions act as intermediary elements between the support portions and the core. Instead of directly supporting the core, the support portions connect through dampers that mediate the force transmission, filtering out harmful vibrations while still providing necessary support
2Reliability
If damper portions are added to the accommodation apparatus to reduce vibrations, then the defect rate of copper foil decreases, but the device complexity increases
Solution Approach 1:
The patent applies local quality by placing dampers only at specific critical locations where vibrations would directly transfer to the core, rather than throughout the entire structure. The damper portions are strategically positioned between the support portions and the core to provide targeted vibration reduction where it is most needed
Solution Approach 2:
The accommodation apparatus combines different material properties by integrating damper portions made of vibration-absorbing materials with the rigid support portions. This composite structure leverages the rigidity of support elements for structural integrity while using the damping materials to absorb vibrations, creating a multi-functional system
3Device complexity
If the core is directly supported without damper portions, then the accommodation apparatus is simpler, but vibrations during transportation cause shocks to the copper foil
Solution Approach 1:
The damper portions serve as intermediary elements that come between the support portions and the core, mediating the transmission of forces. They allow the support structure to remain simple while filtering out harmful vibrations through the intermediary damping layer
