Handheld pattern creating device and method of use of same

摘要

A handheld pattern creating device and method of use of the same are disclosed. In one embodiment, a rotational member is rotatably positioned within a housing under the power of a first drive mechanism to angularly traverse an x-y plane. A rail track is disposed on a surface of the rotational member in order to provide a radial path for a carriage that houses a tool tip. A guide track disposed on the surface of the rotational member includes a curved portion that provides a non-linear path. A second drive mechanism drives the carriage transversely along the radial path of the rail track such that a flexible rack gear travels the non-linear path of the guide track.
