Latest Patents

One of Harigai's latest patents is the oscillating shaver. This innovative device features a battery-powered motor that rotates an eccentric element within the head portion of the razor handle. This design generates an oscillating vibration signal that is transmitted to the razor blade cartridge, effectively desensitizing the facial nerves from the discomforts of shaving. The vibration is partially damped in the direction perpendicular to the surface of the cartridge that engages the user's face, ensuring that the blades mounted in the cartridge do not chop at the whiskers of the user's beard during shaving.

Another remarkable invention is the hand-held hair dryer with a shock-mounted quartz tube heater. This hair dryer utilizes a quartz glass tube heater to produce radiant heat and includes a shock mount sub-assembly designed to resist breakage of the tube during drop tests or other selected concussions. The shock mounts consist of flexible and resilient spring members that allow slight but controlled movement of the tube without breakage, regardless of the direction of impact or orientation of the hair dryer when dropped. Additionally, an internal blower may be included to create airflow through the quartz tube heater, serving as a safety feature to prevent overheating.
