Abstract: A cartridge for a razor comprises a plurality of blade supports, wherein at least one blade support further comprises a blade attached to an inner surface of the at least one blade support that faces away from a shaving surface, wherein the at least one blade support comprises a first optical feature disposed on a portion of an outer surface of the at least one blade support that faces towards the shaving surface, and wherein the first optical feature is a first thermochromic portion configured to change colour based on a temperature of the at least one blade support according to a first temperature response of the first thermochromic portion.

Abstract: A razor cartridge comprising: a housing extending longitudinally along a longitudinal axis, wherein the housing comprises a leading longitudinal side, a trailing longitudinal side, and a recess in between the leading and trailing longitudinal sides for accommodating a group of cutting members, and a group of cutting members comprising a plurality of cutting members disposed at least partially in the recess, wherein each cutting member is arranged between a leading longitudinal side and a trailing longitudinal side of the recess in a shaving direction of the razor cartridge. A first cutting member of the group of cutting members comprises a first blade support having a first blade mounting portion disposed on an inner surface of the first blade support that, in use, faces away from a shaving plane, and a first blade attached to the first blade mounting portion.

Abstract: A cartridge for a razor comprises at least one blade and a first blade support configured to attach the at least one blade to the cartridge. The first blade support includes a first portion, a second portion, and a third portion, a first optical feature provided on one or more of the first portion, the second portion, and the third portion. The first optical feature is selected from one or more of a color, a coating, a texture, a perforation, a transparency of the blade support, a light emitting source, a protrusion and a sticker.

Abstract: A blade assembly comprising a housing having a recess defining a first wall on a first side of the housing and a second wall on a second side of the housing; an elongated body that is attached to the first and second walls and is rotatable about a longitudinal axis (S-S), the elongated body having two or more facets, wherein at least one of the facets has a lubricating element disposed thereon; and a locking mechanism a configured to releasably lock the body in a use position.

Abstract: A system and a method are provided for a voice-activated command or query regarding a purchase of, or information regarding, replacement shaving cartridge(s) inputted via a microphone/speaker associated with a “smart” shaving razor having hardware and software capabilities to function as a stand-alone Internet-of-Things (IoT) device. The command or the query is transmitted, via an Internet gateway connected to the Internet, to a vendor platform connected to the Internet. A response transmission from the vendor platform in response to the command or the query regarding a purchase of, or information regarding, replacement shaving cartridge(s) is processed by the control unit. The microphone/speaker outputs a natural-language voice output corresponding to the response transmission from the vendor platform.

Abstract: The present disclosure provides a smart shaving system with a 3D camera to assist the user of a shaving razor, which 3D camera is communicatively connected to the shaving razor and to a razor cartridge vendor platform via an Internet-of-Things (IoT) gateway. The 3D camera can be incorporated into the shaving razor, which razor has hardware/software capabilities to function as a N stand-alone Internet-of-Things (IoT) device. The 3D camera can be communicatively connected to the shaving razor and/or to a razor cartridge vendor platform via an Internet-of-Things (IoT) gateway to (i) assist the user to determine whether a particular skin surface area has been adequately shaved, and/or (ii) assist the user regarding the type of shaving cartridge and/or razor suited for the particular user's physical characteristics (e.g., skin and/or hair).
