Shaving Device With a Razor Blade
Our partner, a Croatian SME has developed a novel invention which is a device for manual shaving with one or more blades, which perform a vibrating motion perpendicular to the direction of the cut and parallel to the cutting edge of the blade. Thanks to this, cutting of hair actually becomes sawing of hair. As sawing requires less energy than cutting, the act of shaving becomes easier and more enjoyable. Background information There are many razors with one or more blades on the marker today. In all of these razors, the blade is firmly connected to the razor handle, so that the blade always follows the direction of the movement of the hand, or i.e. the razor handle. The razor handle movement is such that the blade slides over the skin and encounters hairs which it then cuts. The cutting edge of the blade is therefore moving in the direction of the cut. There are razors which have an electrical motor in it, with an excenter on its axle. The result of rotating the axle with the excenter is vibration of the handle, and consequently of the blade. If we imagine a point on the blade, then this point will perform a circular motion. The rotation axis of this circle is parallel to the skin and the axis of the electric motor, so that the circular motion of the blade results in clinic contact of the blade to the face, in accordance to the revolving rate of the motor axle. Innovation of the product In the theory of cutting it is well known that less cutting force is needed if the blade performs a two way movement, one in the direction of the cut and the other in a direction perpendicular to the first one. The perpendicular direction is also parallel to the cutting edge of the blade. This is easy to imagine if we think of even the finest blade, such as a razor blade, as a tiny saw with microscopic teeth. If we looked at a razor blade through a microscope, we would see microscopic teeth, just not all the same and regularly spaced like we would find on a saw. When we understand this, that every blade is essentially a saw, it becomes clear that when we perform a motion perpendicular to the cut, and parallel to the blade, we are actually sawing. Therefore, if we introduce an additional blade movement in the direction parallel to the blade, than we will not be cutting the hair, but sawing it, which is far easier then cutting.
Sector: Other Technologies n.e.c.
Country: Hungary
Area of Application: The invention is suitable for use in manual shaving. It is characterized by ease of shaving because the hairs are cut by sawing, rather than cutting, as they are in present practice. The invention is applicable to shaving devices with one or more blades.
