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

VSEngineering 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

Engineering Contradiction:
Improvecopper foil qualityVSAvoidaccommodation apparatus structure
Core Design Contradiction:
ReliabilityVSDevice complexity

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

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

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

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Engineering Contradiction:
Improvecopper foil defect rateVSAvoidaccommodation apparatus components
Core Design Contradiction:
ReliabilityVSDevice complexity

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

Inventive Principle:
Principle #3Local quality

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

Inventive Principle:
Principle #40Composite materials

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

Engineering Contradiction:
Improveaccommodation apparatus structureVSAvoidvibrations and shaking
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

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

Inventive Principle:
Principle #24Intermediary (Mediator)
