DIGITAL COMMUNICATION ON RAZOR CARTRIDGE, HANDLE AND CHARGING BASE

Abstract

A razor includes a blade cartridge with multiple blades removably and pivotally attaches to a handle. The blade cartridge and handle include microprocessors for wireless communication between the handle and blade cartridge, via near field communication or RFID. A charging base allows for charging a rechargeable power source in the handle and is further adapted to communicate with a smartphone, computer or other electronic device via wired and/or wireless communication. A mobile application on the smartphone is able to communicate with the charging base, while also providing for wired or wireless communication with remote servers/cloud infrastructure and/or the Internet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Referring to the several views of the drawings, the razor of the present invention is shown schematically and is generally indicated as 10. The razor 10 has a blade cartridge 20 that includes at least one blade 22 and preferably multiple blades 22. The razor cartridge is pivotally and removably attached to a handle 30. The razor 10 includes microprocessors for collecting, storing and transferring data. In one embodiment, as shown in FIG. 1, the blade cartridge 20 includes a microprocessor 24 that uses near field NFC (near field communication) and/or RFID (radiofrequency identification). The microprocessor 24 is embedded into the cartridge 20 and allows for unique identification of the cartridge 20 as well as memory. The microprocessor 24 has an NFC chip 26. The handle 30 of the razor 10 also includes a microprocessor 34 with an NFC communication chip 36 as well for wireless communication with the microprocessor 24 in the blade cartridge. Additionally, a wireless charger device 40 (i.e., charging base) allows for bidirectional communication between the handle 30 and the charging base 40. This provides for the ability to synchronize data between the blade cartridge 20, the handle 30 and the charging base 40.

[0014] In a further embodiment, as shown in FIG. 2, the charging base 40, in addition to providing the function of a wireless charger for charging a power source 38 in the handle 30 and/or blade cartridge, also includes wired and/or wireless communication components and functionality to allow wireless communication with a smart phone 50, computer 60 or other electronic device. The smart phone 50 will have a computer application (i.e., mobile app) to communicate with the charging base 40 (smart base), while also providing a means for wired or wireless communication with remote servers/cloud infrastructure and/or the Internet. In another embodiment, the handle communicates with the smart phone directly via low energy wireless communication.

[0015] In yet a further embodiment, as seen in FIG. 3, a microphone 70 is provided in the handle 30 of the razor 10. The microphone 70 receives noise as the user shaves. As the blades 22 move along the skin surface, the cutting of the hairs creates a noise. By measuring the envelope of the noise, as well as the frequency of the noise/pitch of the noise, the speed of the shaving strokes can be determined. Knowing the speed of the shaving strokes and the time that each stroke takes, the distance of travel of the blades 22 across the skin surface is easily calculated. The calculated distance is metered (i.e., added to the sum total of previously calculated shaving stroke distances) for each blade cartridge. By sharing this data with a cloud-based service, a notification can be sent to the user of the razor 10 indicating that the cartridge 20 (i.e., useful life of the blades) has expired or is about to expire, along with instructions that the user will need to replace the blade cartridge 20 to ensure a smooth shave.

[0016] This allows a razor supply service to trace the supply chain. Because each cartridge has a unique ID, by having the database of those cartridges beforehand, the supply service can always trace them to the end user. This allows a lot of insight to the supply chain and to the shaving habits of the user. For example, a smart phone application can trace how often the user shaves and can remind the user when they need a shave.

[0017] Additionally, the user can re-order the blade cartridges either automatically via the smart phone application or manually. Since each blade cartridge has a unique ID, each blade cartridge can be identified to a specific user. The user can then be alerted if they are about to use someone else's blade cartridge, which may be beneficial for sanitary reasons.

[0018] In addition to communication, at least one embodiment of the charging base 40 can have HMI (human machine interface). Additionally, the blade cartridges 20 can be heated to sanitize the blades 22 and anneal the blade material because when the blade material is annealed you have better cutting properties. If the charging base 40 is provided with a heater device 44 and is covered, we can controllably heat up/overheat the blades 22 to sanitize the blades 22 by killing the bacteria above 180-200 degrees Fahrenheit (the blades 22 and cartridge 20 could potentially be heated to 300 degrees Fahrenheit because the plastic would not melt up to this temperature). This will prolong the life of the blades 22.

[0019] Annealing the metal: aligning all the lattices in the metal. When the metal blades 22 are heated (e.g., above 200 degrees Fahrenheit) and then slowly cooled down, all the lattices in the metal in the structure are aligned, instead of being randomly arranged. The benefit of the lattices aligned is better cutting properties. Instead of being jagged edges on the blade 22, you have smooth edges. Another benefit is it helps to make the blades 22 last longer. Annealing softens it slightly so the lattices will be aligned. Another benefit of heating the blades 22 is killing the bacteria to thereby sanitize the blades and burn away whiskers, skin and oils that remain on the blades surfaces after shaving. This may require heating the blades 22 to 350-400 degrees Fahrenheit. To protect the user, the cover 42 of the charging base 40 can be provided with a safety mechanism which will prevent removal of the cover 42 when the blades 22 are above a certain temperature.
