Abstract: A method for regulating current flow in a wet shave razor includes one or more conductive materials, such as metals, in electric circuit connection, wherein each conductive material has unique resistance properties and is used to regulate the amount of current (i.e. heat) flowing to at least one electrically powered component on the blade cartridge, and particularly one or more electrically powered devices/elements on the blade cartridge such as, but not limited to, one or more blades, one or more heating elements, a vibration device, illuminating device (e.g. LED or bulb), gauges, or indicators. The length and thickness of the conductive materials used in the electric circuit further affects the total circuit resistance and, accordingly, the amount of current flowing to the blade cartridge for heating the blades. In other embodiments, the dissimilar material conductors may be used to regulate current flow to alternative electrically conductive components.

Abstract: A blade cartridge for a shaving razor contains a series of parallel blades and at least two contact segments as part of an electric circuit connected to the blades at spaced intervals to provide an electric current flow through the blades in a manner that provides more efficient heat distribution across the length of the blades. A radiator effect is created wherein heat produced by the contact segments passes between the blades towards the cutting edge of the blades. The combination of the heat produced by the electric current flow through the conductive blades and the heat produced by the contact segments provides a dual heat process that makes it easier to adjust and control the temperature to a desired stable heat temperature. A thin conductive film may be fitted to be in contact with the ends of the blades to insure conductivity throughout the entire length of each blade.

Abstract: A blade heating system for a heated razor includes electrically conductive blades contained in a blade cartridge. A switch lever is hingedly attached to the blade cartridge and is selectively positionable between a closed position, wherein the switch lever is closed against the back of the blade cartridge, and an open position, wherein the switch lever is opened away from the back of the blade cartridge. Electrically conductive leads are connected to positive and negative terminal ends of a battery carried on the switch lever. One or more electrically conductive blade contacts are provided for electrically connecting the one or more blades to the conductive leads and battery when the switch lever is in the closed position for delivering electric current to the one or more electrically conductive blades. In a preferred embodiment, magnets are used to releasably hold the switch lever closed against the back of the blade cartridge.

Abstract: A shaving razor includes one or more heaters held in spaced, adjacent relation to the rear non-cutting edge of at least one blade of the razor. The one or more heaters are in connection with an electric power source, which may be located in the blade cartridge or in the handle of the razor. When the electric circuit is closed and electric current flows through the heaters, the heaters generate heat that is directed between the blades and towards the front cutting edge of the blades in a radiator effect. The heaters serve to warm the blades while also providing warmth to the user's skin for increased shaving performance and comfort. In a preferred embodiment, the heaters are made from a high resistance material, such as Nichrome, for producing heat with maximum efficiency.

Abstract: A blade cartridge for a shaving razor contains a series of parallel blades, and at least two wire conductors of an electric circuit connected to the blades at spaced intervals to provide an electric current flow through the blades in a manner that provides more efficient heat distribution across the length of the blades. The ends of the blades may be held in place by staples that are insulated from the electric circuit.

A radiator effect of the heated blades causes the blades to become warmer when the blades are placed against the skin surface and air is unable to circulate between the blades. The blades become less hot when removed from the skin and air circulates between the blades.
