A method of assembling an electronic subassembly for a personal care product by manufacturing a hollow housing defining a chamber having a first open end and an opposing second open end. A rigid end of a first circuit board is inserted into the first open end of the housing. A second circuit board subassembly having a second circuit board is inserted into the chamber through the second open end. The first circuit board is connected to the second circuit board within the chamber of the housing.

Handle is provided for battery operated razors. In some implementations, the handle includes a simple, efficient mechanism for both securing a battery cover to the handle of a razor and at the same time providing a high reliability electrical contact between the battery and electronics of the razor. The mechanism includes a closing system, including a first conductive component slidably attached within the battery cover and biased toward a predetermined axial position, and a second conductive component secured to the interior wall of the grip portion. The first conductive component is configured to interact with the second conductive component and move axially within the battery cover during engagement of the battery cover with the grip portion.

A razor handle including a handle body and a mechanism for tracking usage of a razor blade or razor blade cartridge. The tracking mechanism includes means to identify a unique razor blade cartridge attachment to the handle body and electronic circuitry disposed within the handle body for automatically tracking razor blade or razor blade cartridge use. The collected data is then sent out to and stored at a remote server.

A shaver, comprising a handle body, a cartridge coupled to the handle body, the cartridge including a skin care treatment head, a transducer configured to generate electrical energy from mechanical energy, thermal energy, sound or acoustic waves, magnetic field and/or radiofrequency energy; and a battery configured to receive electrical energy generated by the transducer.

A razor assembly is proposed. The razor assembly may include a cartridge including at least one blade, and a handle assembly. The handle assembly may include a handle top part positioned at an upper part in an extending direction of the handle assembly. The handle assembly may also include a heating element configured to simultaneously heat the handle top part and the at least one blade in a contactless manner.

A handle for a shaving razor in which the handle comprises a frame and a movable member assembly operably coupled to the frame such that the frame is disposed between the movable member assembly and where the movable member assembly portions are configured to move both above and below the frame. The movement can be linear or rotational. The movable member assembly comprises one or more springs. The first member and the second member are coupled together through said rigid member. The rigid member can include a rigid member platform which has a width to thickness ratio from about 7 to about 60.

A method of manufacturing a shaving razor. A circuit board is positioned within a handle. A first end of a flexible electrical bridge is connected to the circuit board. A second end of the flexible electrical bridge is connected to an energy emitting device. A loop is formed in the flexible electrical bridge by bending the flexible electrical bridge.

A razor cartridge is proposed. The razor cartridge may include at least one razor blade having a cutting edge formed thereon, and a blade housing configured to accommodate the razor blade in a longitudinal direction. The razor cartridge may also include a housing cover including a razor blade window configured to expose at least a portion of the cutting edge and a window frame surrounding at least a portion of the razor blade window and connected to the blade housing. The window frame may include a plastic guard provided in front of the razor blade, and the plastic guard may include a transparent or translucent material.

Some embodiments may include a personal grooming device. Such a device may include a head portion. The head portion may include a means for mounting at least one razor. An embodiment may also include a means for rotating the razor clockwise and/or counterclockwise by a predefined number of degrees less than one full turn.

A trimming assembly for dreadlocks comprises a handle. A cutting head is operatively connected to the handle. The cutting head comprises a cutting head body defining a receptacle at a radial end thereof. The receptacle is structured to receive a dreadlock. A blade protector is positioned axially within the receptacle. A curvature of the blade protector corresponds to a curvature of an inner wall of the receptacle. A blade is interposed between the blade protector and the inner wall. The blade defines a cutting edge at an axial end thereof proximate to the handle. The cutting edge is structured to cut loose hair protruding outwards from the dreadlock as the cutting head is moved along the dreadlock.
