In order to provide a method for the rapid preparation of high-performance fiber materials to meet the medical needs of the army in field emergencies and personal protection, in this work, a portable melt differential electrostatic spinning machine product has been designed. Using the Teoriya Resheniya Izobreatatelskikh Zadatch (TRIZ) theory, we analyzed the traditional process for designing a portable melt differential electrostatic spinning machine and optimized the melt conversion, electric field generation and control system using the invention principles of splitting, extracting and nesting. The resulting innovative portable melt differential electrostatic spinning machine can effectively address the many limitations of the traditional spinning machines in different military missions arising from their poor portability, complex operation, insufficient adaptability to the environment and other problems. Our new design is expected to enhance the emergency protection capability and combat effectiveness of the military, provide innovative solutions for the military medical field, and serve as a theoretical reference for further innovation in electrostatic spinning technology and related equipment.
