With a total of three patents to his name, Ahn's work showcases his innovative spirit and technical expertise.

Latest Patents

One of Ahn's latest patents is a "Vibrator for generating horizontal vibration." This invention pertains to a vibration generator used in devices such as mobile phones that require a vibration mode. The horizontal vibration type generator includes a casing that is open on one surface, a vibration part with a weight inside the casing, and a spring mounted within. It produces horizontal vibrations through resonance caused by oscillation in an electromagnetic force matching the intrinsic vibration frequency of the spring. This design addresses the issue of reduced lifespan due to mechanical friction found in traditional mechanical vibration generators, while also generating a substantial vibration force despite its thin construction.

Another significant patent is the "Step motor," which is a PM type step motor designed for moving cameras or optical pickup lenses in media-related equipment. This step motor features a stator unit comprising first and second stators that are coupled together, each equipped with a bobbin and a yoke. The terminal blocks of the stators are spaced apart, facilitating an automatic winding operation using winding equipment. The motor also includes a bushing with a central through hole for the rotating shaft, designed in a two-stage structure for easy coaxial arrangement of the stator unit, rotating shaft, and casing unit.
