Abstract

An intelligent shaving system is disclosed herein including a system having a handle, a cutting member operably coupled to the handle, a sensor configured to detect a parameter representative of hair density on a region of skin of a user as the cutting member traverses the skin of the user, and a microcontroller. The microcontroller is operably coupleable to the sensor and configured to determine a density of the hair based on the detected parameter, and generate an instruction based on the determined density of hair.

Claims (33)

1 . A shaving system comprising:

a handle;

a cutting member operably coupled to the handle and configured to contact a region of skin of a user;

a sensor configured to detect a parameter representative of hair density on the region of skin as the cutting member traverses the skin of the user; and

a microcontroller operably coupled to the sensor and configured to:

determine a density of the hair based on the detected parameter; and

generate an instruction based on the determined density of hair.

2 . The shaving system of claim 1 , wherein the cutting member is a first cutting member releasable from the handle such that a second cutting member can be operably coupled to the handle.

3 . The shaving system of claim 1 , further comprising:

a feedback indicator disposed on the handle.

4 . The shaving system of claim 3 , wherein the microcontroller is further configured to generate a signal to cause the feedback indicator to illuminate.

5 . The shaving system of claim 1 , wherein the sensor is a first sensor, the shaving system further comprising:

a second sensor configured to detect a parameter representative of a stroke of the cutting member as the cutting member traverses the skin, and wherein:

the microcontroller is operably coupled to the second sensor and is configured to:

determine a stroke characteristic based on the detected parameter associated with the stroke; and

generate a stroke performance indicator based on the determined stroke characteristic.

6 . The shaving system of claim 5 , wherein the microcontroller is configured to generate the stroke performance indicator further based on a comparison between the stroke characteristic and a threshold characteristic.

7 . The shaving system of claim 5 , wherein the second sensor is a load sensor, an optical sensor, a movement sensor, a friction sensor, or a temperature sensor.

8 . The shaving system of claim 5 , wherein the stroke characteristic includes at least one of a stroke count, a stroke direction, a stroke pressure, a stroke duration, or a stroke acceleration.

9 . The shaving system of claim 5 , wherein the stroke characteristic is indicative of a remaining life of the cutting member.

10 . The shaving system of claim 5 , wherein the microcontroller is further configured to generate a message configured to display the stroke performance indicator to the user of the shaving system.

11 . The shaving system of claim 5 , further comprising:

a feedback indicator, and wherein the microcontroller is further configured to generate a signal to cause the feedback indicator to provide feedback representative of or based on the stroke performance indicator to the user.

12 . The shaving system of claim 5 , wherein the stroke performance indicator is a quantitative indicator.

13 . The shaving system of claim 1 , wherein the sensor is a first sensor, the shaving system further comprising:

a second sensor configured to detect a force exerted by the user; and

a feedback indicator configured to generate an indication based on the force detected by the second sensor,

the microcontroller being operably coupled to the second sensor and the feedback indicator, and configured to generate a signal based on the detected force and send the signal to the feedback indicator such that the feedback indicator generates the indication,

the feedback indicator including an indicator display and the indication includes illumination of a light of the indicator display,

the second sensor including at least one of a force cell or a load cell.

14 . The shaving system of claim 1 , wherein the sensor is an optical sensor or a camera.

15 . The shaving system of claim 1 , wherein the microcontroller is configured to determine the density based on a stroke of the cutting member as the cutting member traverses the region of skin.

16 . The shaving system of claim 1 , wherein the sensor is a load sensor, a movement sensor, a friction sensor, or a temperature sensor.
