Innovation of Device for Nanofibers Production Using TRIZ

The paper dealswith the innovation of the device for nanofibers producing from a free surface of polymer solution. The collector (negative electrode) is one of the main parts of the device. The original flat collector did not provide sufficient results at producing 3D nanostructure. The production of 3D nanostructure demands high intensity of electrostatic field (big force) for obtaining sufficient productivity but at the same time low intensity of electrostatic field (small force) for obtaining required 3D nanostructure at the collector. This problem can be solved by the use of the method Theory of Inventive Problem Solving (TRIZ) and its tools for physical contradiction solving. The defining of the physical contradiction, resolving the contradiction by the use of separation and also inventive principles (especially principle nr. 9 Preliminary anti-action) are described in the paper. The idea of collector innovation has been confirmed by the numerical simulation FEM and verified by the experimental way.
