Copper Foil Roll Support Structure for Transport Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Copper foil defects occur during transportation due to vibrations and shaking, which are transferred through conventional accommodation apparatuses, leading to quality issues and instability.
Innovation Solution
An apparatus with an accommodation body, support portions, and an elastic member that includes body portions with first and second protrusions, effectively buffering vibrations by providing a damping mechanism between the core and support portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If copper foil is transported using a conventional accommodation apparatus that supports the core directly, then the structure is simple and easy to manufacture, but vibrations and shaking during transportation are transferred to the copper foil causing defects
Solution Approach 1:
An elastic member is introduced as an intermediary between the support portion and the core. This elastic member absorbs and dampens vibrations during transportation, preventing them from being transferred to the copper foil. The elastic member acts as a mediator that isolates the copper foil from harmful vibrational forces while maintaining structural support.
Solution Approach 2:
The elastic member provides beforehand cushioning by being pre-installed between the support portion and the core. This cushioning mechanism is in place before transportation begins, ready to absorb and mitigate vibrations and shocks that will occur during transit, thereby preventing defects in the copper foil before they can happen.
2Reliability
If vibrations are buffered using an elastic member with protrusions, then the defect rate of copper foil is reduced, but the device complexity increases
Solution Approach 1:
The elastic member is segmented with multiple first protrusions and second protrusions arranged in specific patterns. These protrusions divide the elastic member into functional zones that work together to dampen vibrations from different directions. The segmentation allows the elastic member to handle complex vibrational forces more effectively while maintaining a manageable structural design.
Solution Approach 2:
Different regions of the elastic member have different local qualities through the arrangement of protrusions. The first protrusions extend in the longitudinal direction of the core while the second protrusions extend perpendicular to them, creating areas with varying stiffness and damping characteristics. This local quality variation optimizes vibration buffering in different directions without requiring a completely complex overall structure.

AI summary
The present disclosure relates to an apparatus for accommodating copper foil. The apparatus includes an accommodation body having an accommodation space which accommodates copper foil wound on a core, a support portion coupled to the accommodation body and configured to support both ends of the core, and an elastic member disposed between the support portion and the core and configured to support the core. Here, the elastic member includes a body portion, a plurality of first protrusions arranged on a top surface of the body portion and extending in a longitudinal direction of the core, and a plurality of second protrusions arranged on a bottom surface of the body portion and extending in a direction perpendicular to the extending direction of the plurality of first protrusions. Accordingly, vibrations may be buffered in a frequency band of vibrations occurring in a transportation process.
