Double-Sided Coating Support Structure for Stable Foil Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coating apparatuses face issues with foil stability during transportation after double-sided coating, leading to reduced coating quality due to shaking, which is not addressed by existing technologies like JP 6742856B2.
Innovation Solution
A double-sided coating apparatus with a supporting assembly comprising a supporting wire wound bar and adjusting mechanisms to stabilize the foil during transportation, ensuring it does not shake, using rollers and air-floating plates to maintain stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the foil is transported after double-sided coating while the slurry is still liquid, then the coating process can be completed efficiently, but the foil shakes and coating quality deteriorates
Solution Approach 1:
The patent introduces a supporting wire wound bar as an intermediary element between the coating die and the foil. This supporting structure provides immediate support to the foil after coating, preventing shaking during transportation while maintaining the efficiency of the coating process. The supporting wire wound bar acts as a mediator that stabilizes the foil without interfering with the coating application.
2Manufacturing precision
If a supporting structure is added to prevent foil shaking, then coating quality improves, but device complexity increases
Solution Approach 1:
The patent employs a supporting wire wound bar, which is a flexible thin-wire structure, to provide support to the foil. This flexible supporting structure effectively prevents foil shaking and improves coating quality without introducing bulky or complex mechanical components. The thin-wire design minimizes the increase in device complexity while achieving the desired stabilization effect.
