DEVICE FOR FORMING SURFACE PATTERN ON FLUID, AND FORMING METHOD THEREOF

WIPO Patent Application WO/2010/053231

A1

A device for forming a surface pattern on fluid according to the present invention comprises: fluid that can be hardened under certain conditions; a base unit onto which the fluid is applied; and a vibration unit that vibrates the fluid to create a waveform on the surface of the fluid. A method for forming a surface pattern on fluid according to the invention comprises: a fluid-receiving step for applying the fluid to the base unit; a vibration step for creating a waveform on the surface of the fluid by applying vibrations to the fluid on the base unit; and a hardening step for hardening the fluid on which the waveform is created. The disclosed device and method have an advantage to easily form various patterns on the surface of the fluid using the vibration unit that applies vibrations to the fluid, wherein the vibrations may have various waveforms, frequencies, and amplitudes. The invention also enables the formation of patterns on the surface of the fluid without mechanical contact, so there is little restriction in the pattern size and the production cost of the pattern can be saved. Furthermore, there is an advantage that an additional precision mold is not required to form a fine pattern on the surface of the fluid.
