Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing equipment for manufacturing ceramic wires faces challenges in productivity due to contamination and inefficiencies in the deposition process of superconducting thin films, particularly when reels are replaced, leading to defects and reduced output.
Innovation Solution
The introduction of buffer units between the loading/unloading and deposition units, which include buffer chambers, reel-to-reel devices, and clamp parts to maintain a vacuum state and continuously provide the wire substrate, preventing contamination and ensuring seamless reel replacement without exposing the substrate to air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If reel replacement is performed in existing equipment, then productivity is reduced due to contamination and process interruption, but device complexity increases with the addition of buffer units
Solution Approach 1:
The equipment is divided into separate functional units: a deposition unit for ceramic wire deposition, a loading/unloading unit for reel replacement, and buffer units that connect them. This segmentation allows the deposition unit to operate independently and continuously while the loading/unloading unit performs reel replacements without interrupting the deposition process, thereby resolving the contradiction between productivity and device complexity.
Solution Approach 2:
Buffer units are introduced as intermediary components between the deposition unit and the loading/unloading unit. These buffer units temporarily store wire substrates and maintain vacuum isolation, enabling seamless transitions during reel replacements. The buffer units act as mediators that decouple the deposition process from the reel replacement operations, preventing contamination and maintaining productivity while managing the increased device complexity through functional modularization.
2Manufacturing precision
If reel replacement is performed without buffer units, then device complexity is lower, but manufacturing precision deteriorates due to contamination of the superconducting thin film
Solution Approach 1:
The buffer units maintain a vacuum environment (inert atmosphere) that isolates the wire substrate from air contamination during reel replacement operations. The vacuum isolation ensures that the superconducting thin film deposited on the wire substrate remains free from oxidation and other atmospheric contaminants, thereby preserving manufacturing precision. The vacuum environment is maintained throughout the buffer unit structure, including during clamp part operations and reel transitions.
Solution Approach 2:
The buffer units serve as intermediary vacuum-isolated chambers that protect the wire substrate during reel replacements. By introducing these intermediary buffer zones, the system maintains vacuum isolation between the deposition unit and the atmospheric loading/unloading unit, preventing contamination while managing device complexity through functional separation.
3Productivity
If reel replacement interrupts the deposition process, then device complexity is lower, but productivity decreases due to process interruption and contamination
Solution Approach 1:
The buffer units enable continuous operation of the deposition unit by decoupling it from the reel replacement operations. The wire substrate is continuously fed through the buffer units from the loading unit to the deposition unit, and the deposited wire is continuously transferred to the unloading unit. This continuous flow allows the deposition process to proceed without interruption during reel replacements, maintaining productivity while managing device complexity through functional modularization.
Solution Approach 2:
The equipment is segmented into independent functional units that can operate asynchronously. The deposition unit continues its useful action of depositing ceramic wire while the loading/unloading unit performs reel replacements. The buffer units connect these segments, allowing the continuous deposition process to proceed without being interrupted by reel replacement operations, thereby resolving the contradiction between productivity and device complexity.

AI summary
Equipment for manufacturing ceramic wires is disclosed. The manufacturing equipment can comprise a deposition unit for depositing the ceramic wire on a wire substrate, a loading/unloading unit having a release reel for providing the wire substrate to the deposition unit and a coiling reel for discharging the wire substrate from the deposition unit, and at least one buffer unit arranged between the loading/unloading unit and the deposition unit. The buffer unit may continuously be providing the wire substrate to the deposition unit or continuously winding the wire substrate from the deposition unit when the release reel or the coiling reel is replaced.
