Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fullerene production methods, such as the arc process, suffer from low production efficiency and capacity, making it difficult to meet the increasing demands for fullerene and metal fullerene in industrial scales, as existing laboratory equipment is inadequate for large-scale production.
Innovation Solution
A fullerene arc source with a closed electrode circuit is designed, allowing multiple independent arc sources to be installed on a single furnace, featuring an anode, cathode, and cathode trigger forming a closed current circuit, with an automatic pushing system to maintain arc formation and a vacuum furnace setup for simultaneous operation of multiple arc sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single arc source is installed in a single furnace with linearly arranged anode and cathode, then the structure is simple, but the production efficiency is low
Solution Approach 1:
The patent divides the electrode circuit into multiple independent arc sources within a single furnace. Each arc source consists of an anode, cathode, and cathode trigger forming a closed circuit. This segmentation allows multiple arc discharges to occur simultaneously at different positions, transforming a single low-productivity arc into multiple parallel arcs, thereby significantly increasing fullerene production efficiency while maintaining manageable structural complexity through modular design
Solution Approach 2:
The patent transitions from a one-dimensional linear arrangement of single anode-cathode pairs to a multi-dimensional spatial configuration with multiple arc sources distributed throughout the furnace. By utilizing three-dimensional space for electrode placement and implementing closed circuit designs that allow electrical connections through various paths (including external circuits and furnace wall integrations), the system achieves higher productivity without proportionally increasing structural complexity
2Productivity
If multiple arc sources are installed on a single furnace, then the production capacity increases, but the device complexity increases
Solution Approach 1:
The patent designs a universal furnace structure that can accommodate multiple arc sources with standardized electrode configurations. The furnace is equipped with multiple mounting positions for anodes and cathodes, and the electrical system includes common power supply connections and control mechanisms that can manage multiple arc sources simultaneously. This multi-functionality allows the same furnace structure to handle increased production capacity without requiring fundamentally different design approaches for each additional arc source
Solution Approach 2:
The patent combines multiple arc sources within a single integrated furnace system, sharing common infrastructure elements such as the vacuum chamber, cooling systems, power supply units, and control mechanisms. By merging these supporting systems rather than providing separate installations for each arc source, the patent achieves increased production capacity while limiting the growth of overall device complexity through resource consolidation and shared components

Function Achieved in This Case
This configuration significantly enhances production efficiency and capacity, enabling continuous and automatic mass production of fullerene and metal fullerene, replacing laboratory-scale production with industrial-scale capabilities.
Implementation Method 1
When a triggering end of anode contacts with the cathode trigger, an arc is formed to evaporate the triggering end of the anode to form a mixture containing fullerene therein

AI summary
A fullerene arc source and a fullerene production apparatus comprising the arc source. More than one independent arc source (2) is mounted in a vacuum furnace (1). Each arc source (2) comprises an anode (21) and a cathode trigger (23). The anode (21) is in contact with the cathode trigger (23) to generate an arc and a triggering end of a positive electrode is vaporized to produce a mixture comprising the fullerene. The multiple arc source (2) in the vacuum furnace (1) simultaneously work to industrially produce the fullerene in a mass manner.
