An intelligent shaving system is disclosed herein including a system having a handle, at least one blade connected to the handle, a microcontroller attached to the handle, a wireless communication unit configured to send and receive data from microcontroller to an external device, a memory configured to store data applicable to the at least one blade, and one or more sensors configured to send sensory data from the one or more sensors to microcontroller. The one of the one or more sensors is a proximity sensor or a camera having image sensor configured to capture video and/or still images. The shaving system assists in determining blade attrition and provides indicators to assist in shaving techniques. The shaving system further may include at least one blade slightly curved to follow a tangent of the skin. The at least one blade may have a nanolattice structure.

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.

According to an aspect, there is provided a computer-implemented method (100) for monitoring usage of a cutting element of a hair cutting device, the method comprising: receiving (102) pressure data indicative of a pressure applied by a cutting element of a hair cutting device on a surface at intervals during a cutting event; storing (104) the received pressure data in a storage device; estimating (106), based on pressure data stored in the storage device in relation to the cutting event and on pressure data stored in the storage device in relation to one or more previous cutting events, a level of wear of the cutting element; and providing (108) an indication of the estimated level of wear for presentation to a recipient.

A blade is described. This blade includes a substrate having two surfaces that meet at a cutting edge of the blade. At a given location along a length of the cutting edge, the two surfaces are at an angle with respect to one another. Moreover, angles between the two surfaces are different at at least two locations along the length of the blade. In particular, the angles between the two surfaces may vary along the length of the blade. Furthermore, the blade may include islands having top surfaces positioned at other locations along the length of the blade. These islands may protrude above the cutting edge to protect skin of a user when the blade is used to cut hair. In addition, the islands may include fluidic channels that provide a fluid (such as air or a lubricant) at the top surfaces of the islands when the blade is used.

A sacrificial anode contains a powerful magnet which pulls it against an object comprising ferromagnetic metal and thus fastens the anode to the ferromagnetic metal. The magnet itself is encased in an electrically inert substance and thus does not corrode.

A plurality of retainers operable to secure a plurality of blades within a housing of a shaving blade unit. The plurality of retainers extending along a pair of side edges of the housing, between a front edge of the housing and a rear edge of the housing.

Included are embodiments for device tuning. Some embodiments of the method include identifying a razor device, where the razor device includes a sensing system, determining a first operating parameter of the razor device, where the first operating parameter relates to the sensing system, and providing a user interface to a user, where the user interface includes a user option to adjust the first operating parameter.

Sensor-based systems and methods of analyzing shaving usage based on time duration and shave event status. A shaving device comprises a blade. The shaving device is communicatively coupled to a sensor and one or more processor(s). Sensor data is collected from the sensor while a user is shaving, and user-specific pressure data is determined therefrom to define shaving stroke(s) based on pressure applied to the user's skin. Based on the one or more shaving strokes and timer intervals thereof, a total duration can be tracked. In addition, a shaving event can be determined based on the shaving stroke(s). An output associated with the shaving device may be generated based on the determining that each of a predetermined duration threshold value and a predetermined shave event threshold value has been met or exceeded, the output comprising an indication that the each of the thresholds has been met or exceeded.
