Apparatus for connecting hair pigment dispenser

Abstract

The present invention relates to a hair pigment dispensing ("HPD") device that can be connected to the Internet and is intended for professional hair stylists to prepare hair color formulas. Hair dyeing is a process that can take several hours and requires precision measurements, high attention to detail, and informed decision making. Needless to say, hair dyeing requires a large inventory of products to be readily available to the hair stylist. The present invention aims to reduce errors in product measurements, inventory sizes, and time spent mixing hair color compositions to improve the overall experience of both hair stylists and customers. Furthermore, the present invention offers the advantage of storing data from various customer mixes either locally or in a cloud server so that customers can receive uniform coloring.

Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This application claims the benefit of U.S. Provisional Patent Application No. 63 / 301,560, filed Jan. 21, 2022, which is incorporated herein by reference. [Background technology]

[0002] The present invention is directed to a hair pigment dispensing ("HPD") device that can be connected to the Internet and intended for professional hair stylists to prepare hair color formulas. Millions of people around the world color their hair. This is a common service offered in beauty salons everywhere. The process begins with a consultation between a hair stylist and his / her customer to determine what the customer wants and the best way to provide their request. After the consultation, the hair stylist decides which formula to prepare to obtain the desired result. The success of this process depends on the expertise of the hair stylist to determine the best formula and the correct measurement of the compositions required for such color. In theory, the hair stylist should keep a note of every formula and measure each composition required by using a scale. In practice, this is not always done.

[0003] The world of hair color is divided into four main categories: permanent dyes, semi-permanent dyes, semi-permanent dyes, and bleaches or lighteners. The permanent and semi-permanent options are oxidative dyes that require mixing the hair color with a hydrogen peroxide solution to activate the color reaction. The hydrogen peroxide solution is commonly called the "developer." From a composition standpoint, the main difference between permanent and semi-permanent hair dyes is that permanent hair dyes contain a higher concentration of alkalizing agents that open up the hair cuticle to allow deeper penetration of the dye. As a result, the permanent color is more effectively deposited into the hair, resulting in longer lasting and providing better gray coverage than semi-permanent hair dyes. Often, one of the most effective alkalizing agents used in hair coloring is ammonia, but alternatives are commonly found in ammonia-free hair dyes, such as ethanolamine. In many cases, the compositions used in permanent and semi-permanent hair dyes are very similar, only differing in the concentrations used (higher or less alkalinity or higher or lower pigment loading).

[0004] Permanent and semi-permanent hair dyes come in liquid or cream consistency, but most hair dyes on the market come in cream format. Permanent and semi-permanent colors are used to achieve a natural looking color and to provide gray coverage. Permanent hair dyes can also be used to lighten hair color depending on the alkalinity and concentration of the hydrogen peroxide solution used to mix the color. The higher the concentration of hydrogen peroxide in the developer, the higher the lightening level. Permanent hair dyes are generally mixed in equal parts with a solution containing 6% hydrogen peroxide (20 volumes) and semi-permanent hair dyes are mixed with a solution containing 3% hydrogen peroxide (10 volumes).

[0005] Semi-permanent hair colors do not require an oxidation process to work and can be applied directly into the hair. The pigments used in this type of hair color are called "direct dyes" and are different from those used in oxidation dyes. Semi-permanent hair dyes do not penetrate into the hair and mostly stay on the surface of the hair. Semi-permanent hair dyes provide temporary results and can fade in a week to a month depending on the pigment concentration. Semi-permanent dyes are those used to achieve intense bright trendy shades (like neons and pastels). The last category of dyes are bleaches or lighteners that do not actually color the hair but do the opposite (remove color). This category usually works by combining a bleach in either cream or powder form with a solution of hydrogen peroxide. It is common for hair color brands intended for professional use to offer more than 50 shades per type of color line (permanent, semi-permanent, and semi-permanent). This results in a significant inventory investment for a hairstylist to have an entire catalog of products for each color line while also considering a larger inventory of the most frequently used colors in stock.

[0006] The most common use of hair coloring is to cover gray hair and restore hair to its natural shade. Hair dyes are unique media in that they process in different ways depending on the type of hair to which they are applied. For example, the same "medium brown" hair dye may look completely different on two people whose hair has different characteristics. Hair coloring has historically been the most challenging job for hair stylists, and it is for this reason that has led to the development of professional hair stylists (technically called "colorists") who specialize in coloring hair. In a survey, only 59% of hair stylists expressed complete comfort with applying hair color. To achieve the correct shade, the professional colorist must consider factors such as the natural hair color, previously dyed hair color, hair texture, hair porosity, and amount of gray hair, as well as the customer's desired post-dye color. There are also some rules of formulation that affect the reaction to "previously colored hair" versus "uncolored hair."

[0007] A hair color prescription or recipe generally consists of at least two different colors in specific proportions mixed with a specific developer strength. Usually, a hair stylist will prepare 2 ounces of hair dye mixed with 2 ounces of developer. As an example, a hair stylist may mix 1 ounce of dark brown, ½ ounce of medium brown, and ½ ounce of golden brown with 2 ounces of 20 volume developer (6% hydrogen peroxide concentration). After the hair stylist comes up with the correct prescription for the client, the mixing process begins. First, each ingredient (hair color and developer) required by the prescription must be precisely obtained and measured. Continuing with the previous example, a hair stylist would need to find a tube of dark brown hair color, a tube of medium brown hair color, and a tube of golden brown hair color and 20 volume developer and precisely measure each ingredient required by the prescription. In a survey, only about 44% of hair stylists measure their color by weight (the most precise form of measurement).

[0008] The relationship between a customer and a hairstylist is usually more important than the relationship between the customer and the salon. It is common for a customer to follow the hairstylist whenever the customer decides to move to a new location. With the advantage of smart phones and other technologies, the salon industry has rapidly changed as hairstylists can now personally perform most of the tasks previously handled exclusively by salons (such as marketing, booking, and credit card billing). As a result, today there are more independent hairstylists than are employed by salons. By some estimates, 55% of hairstylists are self-employed and work by renting a booth either in a salon or in a salon suite. As a result, self-employed hairstylists must rely on themselves to secure their own supplies, such as hair dyes, and to fund their own inventory. Many self-employed hairstylists visit beauty supply stores multiple times a month to minimize the impact of investing in too much inventory. Summary of the Invention [Means for solving the problem]

[0009] The present invention relates to a system and method for a hair pigment dispenser ("HPD"). The HPD assists hairstylists by automatically preparing any desired hair color prescription accurately and quickly, and by maintaining prescription records and tracking inventory usage to aid in the restocking process. In fact, an RFID tag associated with each cartridge cap allows the contents of each cartridge to be closely monitored by the system of the present invention, allowing automatic shipments of new cartridges to be set up and received before the hairstylist even realizes that any cartridge is getting low, thus eliminating the stress of restocking all together. It will be understood that the present invention is not limited to hair color and may be used to dispense other beauty products.

[0010] In the primary embodiment, the invention can be physically interacted with via a touch screen, or remotely via voice commands or a wireless paired device such as a smart phone or computer. The presence of both a speaker and microphone allows for voice features and voice interaction. In simple terms, the HPD receives requests from the hair stylist, determines the required amount of each product based on the request, and prepares a prescription that will achieve the desired result.

[0011] All the necessary ingredients for the various hair color combinations and dye types are contained in the present invention in a traditional pressurized aerosol compatible with a valve that releases the contents under pressure upon activation of the valve. The HPD, hair pigment cartridge ("HPC") and cap are designed to work exclusively with each other. The cap can translate horizontal motion to vertical motion relative to the valve of the aerosol can. In one embodiment, the present invention includes a QR Code label (QR Code is a registered trademark) that comes from a printer associated with the present invention. In another embodiment, the QR Code is replaced by a Liquid Paper LCD display. The purpose of the QR Code or Liquid Paper LCD display is to identify the contents of each cartridge to identify inventory levels, cartridge ownership and other label-based functions.

[0012] One of the basic premises of the present invention is that the number of compositions required to prepare a hair color formula can be dramatically reduced. This is because the present invention functions like an inkjet printer that relies on only four colors (cyan, magenta, yellow, and black) to produce any desired color. In the present invention, combinations of primary colors (red, yellow, and blue) along with precisely mixed basic neutral shades (black, brown, blonde) can provide millions of potential color combinations on demand. Another advantage of the on-demand color mixing provided by the present invention is that it alleviates the need for excess inventory of individually packaged pre-made hair colors. The present invention can also produce various levels of permanent dyes. For example, the present invention can mix both permanent and semi-permanent versions of the same color by simply adjusting the amount of ammonia (or other alkaline agent) on demand to achieve the desired result. In the case of oxidation dyes, the base composition required would be formulated as a traditional semi-permanent color with an additional separate alkaline booster. The HPD can also provide the correct hydrogen peroxide metering required.

[0013] The HPD can operate without any pumps or tubes that can clog, malfunction, or leak. Dispensing occurs from the HPC into a receiving bowl that is used for application onto the customer's hair. Upon identifying the conversion prescription for specific compositions and the amounts required for each of them, the HPD activates a stepper motor that rotates a tray holding the HPC to position the correct compositions above the hair coloring bowl that rests on a scale. The scale measures the amount of each dispensed composition. It should be noted that the terms "HPC", "hair pigment cartridge", "cartridge" and "pigment cartridge" all refer to the same feature of the present invention and therefore may be used interchangeably.

[0014] Once in the correct dispensing position, the HPC can be activated when the linear stepper motor is energized with an electric charge, causing the servo to push a pin through a small opening (in one embodiment, the opening is approximately 3-5 mm in diameter) into the cap. This pushes a built-in mechanism that activates a valve inside the HPC. This motion causes the valve to release the composition contained within such cartridge and dispense it into the bowl. Dispensing stops when the scale measures that the correct amount of each composition has been dispensed. This mechanism is shown in detail in attached Figures 5A and 5B. To stop dispensing, the controller stops the flow of electricity to the linear stepper motor, thus releasing the pushing force and allowing the pin to return to its initial state.

[0015] In alternative embodiments, the function of the scale may be replaced by or combined with a timer mechanism that uses the length of time to dispense product as an indication of how much product to dispense, similar to how a home coffee machine uses time to determine how much water to pour and how "strong" the resulting coffee will be. Alternatively, the scale may be replaced by or combined with a spectrophotometer that records data regarding "absorbed light" versus "unabsorbed light" from a sample color as a reference. This data is then transmitted to software that converts the recorded wavelengths of light into a pigment dispensing recipe to produce the same color as the provided sample.

[0016] In a preferred embodiment, a control printed circuit board ("PCB") provides electrical energy to a linear stepper motor that allows the motor to manipulate the pins to propel them into the cap of the HPC. A linear stepper motor has a threaded shaft that allows for conversion of rotary motion to linear motion. Additionally, the use of a linear stepper motor allows for precise manipulation of the pins. Rather than a simple opening and closing mechanism, a linear stepper motor provides the ability to control the speed of actuator pin movement and the distance the actuator pin travels. This design allows for enhanced precision when it comes to dispensing the correct amount of each product from the cartridge.

[0017] A cell load scale or precision scale located in a tray below the mixing bowl is connected to the PCB to ensure the cap closes when the exact amount of product required is dispensed. When the desired weight of product is detected, the scale relays this to the PCB which stops the flow of current to the linear stepper motor, thus pulling back the pin and closing the valve in the cap to terminate the flow of product to the bowl. An RFID associated with each cartridge cap can communicate with the PCB to ensure the correct product is being dispensed, and can inform the system if the product has already reached a low level in the cartridge and requires a refill. To ensure no product is dispensed when the bowl is not present, a camera capable of scanning a QR code on the bowl detects the presence of a container. If no container is present, the PCB is prevented from sending current to the linear stepper motor and no product is dispensed.

[0018] To precisely position the various compositions to be dispensed, the tray may include a zero position indicator ("ZPI"), which may be a small magnet. The HPD has a position sensor ("PS") in a fixed location that reads the ZPI or magnet if it is near a pole. The software operating the HPD can record the tray position when the sensor makes contact, labels this as position "zero", and uses this as a reference so that the stepper motor can perfectly position the tray to the target location of the composition to be dispensed.

[0019] In one embodiment, the tray holding the HPC may be removable rather than fixed to the HPD to easily switch between the types of compositions used. For example, a hair stylist may quickly remove a tray holding an oxidized HPC and place another tray preloaded with semi-permanent (direct) dye into the HPD (rather than removing one of them at a time). Additionally, the HPD may include a controller with Wi-Fi and Bluetooth connectivity along with on-board software that manages the device's interaction with the hair stylist and how those commands are translated into operations performed by the various electronic components. The HPD may have an active but intermittent internet connection, either directly or via a smartphone, to sync data to the cloud to aid in inventory management and cloud-assisted functions.

[0020] In the main embodiment, the present invention is enabled with internet and Bluetooth connectivity capabilities. The PCBs within the present invention and shown in FIG. 7 (38) provide sufficient connectivity so that various data can be stored, accessed, and used as input for color formula recipes. In some embodiments, the control PCB and all other PCBs contained within the present invention may contain a microprocessor. This microprocessor may perform several roles, including but not limited to: connecting to and providing power to the linear stepper motor to dispense product; storing and retrieving data from a secure cloud network space; and connecting with several other PCBs contained within the present invention and / or within separate units of the present invention to coordinate the flow of the system. Commands for the formation of the desired color may be given to the present invention via hair stylist input or via data from an external or internal database. The PCBs enable internet connectivity and provide the present invention with the ability to store and access data in cloud-based storage.

[0021] If a hair stylist has data regarding all their previous hair dye recipes, this information can be uploaded to the present invention via Bluetooth, USB insert, or other methods, allowing the present invention to access the recipes used and recreate the same colors previously created manually by the hair stylist. The ability of the present invention to store and access data regarding previously desired hair colors allows customer files to be stored to provide each customer with the opportunity to receive the same hair color mix from various salons or hair stylists equipped with the present invention regardless of location or time.

[0022] Several units of the current device can also be connected for synchronized use of multiple systems in a salon setting. This offers the advantage of sending and receiving inputs from one "controller" device, which can be a single system of the invention, via a cloud network or via an independent user interface such as a website or app accessed via a wireless interface, and thus allocating tasks accordingly to several other units to complete several different batches of hair color at once.

[0023] The present invention may also be integrated with a website and / or app where hairstylists and customers who have access to the present invention may create profiles. Upon creating a profile, the user may be prompted to enter their status as either a "hairstylist" or a "customer" to categorize the user into the appropriate interface format. For hairstylists, the app or website may allow for remote calibration of the present invention to ensure that "each cartridge is dispensing the correct amount of product based on the pigments the cartridge itself contains" and to ensure that "no errors occur prior to mixing the desired color." Additionally, hairstylists may have access to data regarding the most frequently requested colors, color approval rates from previous customers, maintenance alerts (such as low battery, low product amount in cartridge, availability of updates, and other important notifications).

[0024] For customers, access to the website or app allows customers to submit reviews of their hair color, compare their previous colors, and "try on" new hair colors before receiving hair dye. After a recent appointment, customers can upload images and reviews via the cloud coloring solutions network of the received hair color and provide details such as how accurate the color was compared to the desired color, how well the color lasted, whether the color treatment caused any damage or structural changes to the hair, and what the overall experience was. These reviews can be associated with the particular system of the present invention with which the customer received their hair coloring. This allows customers and hair stylists to track the performance of the present invention compared to other units of the same device.

[0025] A customer may choose that their review remain confidential for their records or that their review be uploaded to cloud storage (where the hair stylist and the present invention may access the review and determine any changes that may be beneficial for the customer's next appointment). Customers who choose to make their review accessible to hair stylists and the present invention may have their data used and compared across customers to assist the stylist and the present invention in making "informed decisions" regarding new customers' hair. For example, one customer with straight, thick, naturally black hair may review their recent hair coloring as perfect and upload an image of the completed new look. This information may then be used for new customers to search for the same or similar baseline characteristics and the same new color. Based on the image and review, the new customer may choose to receive the exact same color mix, perfectly measured by the present invention to match the desired look previously achieved for the first customer.

[0026] Additionally, customers can upload images of their hair to the website or app to "try on" new hair colors prior to committing to a color appointment. Customers can choose to adjust the shade of their current color or try a completely different look. Using augmented reality ("AR") technology, customers can select new hair colors and hairstyles to try on their images. Once a customer finds a color they like, this information can be visually translated into a unique mix that is sent to the hair stylist and the present invention for the next appointment. Other data such as hairstyle, hair thickness, and previous hair dyeing experience can be associated with the customer, allowing the present invention to determine the exact ratio of each component needed to create the customer's desired color. All customer and hair stylist data is stored and accessed through the Cloud Coloring Solutions Network, which interfaces with the present invention through a connection to the PCB.

[0027] The network used and accessed by the present invention will generally have interconnections between the other components of the system that allow communication between customers and hair stylists for sharing data (such as customer reviews and hair stylist input, as well as instructions for creating hair colors that are stored in a cloud database.) The present invention may further connect to one or more servers and processors to perform several functions related to the computational tasks associated with the present invention (such as storing and accessing data, forecasting desired changes based on customer reviews and other data, and developing a timeline of each customer's hair color journey).

[0028] Some of these elements may or may not be present depending on the implementation and may act independently or may be integrated with each other accordingly. Memory associated with the cloud network and used for storing data may also store software programs (such as operating system software and routines for execution by the present invention and / or associated processors). This memory may include read-only memory ("ROM"), non-volatile writeable memory such as flash memory, and static, dynamic and / or magnetoresistive random access memory ("SRAM", "DRM", "MRAM", respectively).

[0029] In the primary embodiment, the HPD may be powered by a rechargeable battery pack that obtains its power from a detachable power cord, which would preferably have a USB-micro USB format or another standard format, and may take a voltage input of 110-240v, allowing the use of the invention internationally. The purpose of utilizing a battery pack is to allow the HPD to be placed in any location without having a power outlet nearby. In an alternative embodiment, the invention may be adapted to use a standard outlet for power. The USB-C port located on the invention may also be used for connection of a data storage device, such as a hard drive, allowing the hairstylist to back up any data associated with the device on a future basis (although the data may be securely uploaded and stored via a cloud database).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0033] FIG. 1 shows a general overview of a hair pigment dispenser ("HPD"). In accordance with a preferred embodiment of the present invention, the HPD consists of a housing 1 to which a lid 2 is attached, attached via a hinge 30. The lid 2 opens to provide access to the pigment cartridges and other components of the present invention as will be described in more detail in the following figures. Also attached to the housing 1 is an LCD 9. From the LCD 9, a hair stylist can interact with the present invention to select a desired hair color, a desired durability, and provide other commands to and receive notifications from the present system. At the bottom of the housing is a bottom tray assembly 10, on which is placed a bowl 12 containing the composition for the desired hair color mix.

[0034] 2 provides a cross-sectional view of the HPD and its internal workings. In accordance with a preferred embodiment of the present invention, an internal compartment of a housing 1 having a lid 2 contains a rotating tray 3 which holds a cartridge 5 and is powered by a stepper motor 13 to rotate to position the correct composition above a hair coloring bowl 12 which sits on a bottom tray assembly 10. When the correct cartridge 5 is in the correct dispensing position above the bowl 12, a magnet 21 of a linear stepper motor 27 is energized and forces a pin 31 through a small opening into the cap 6 of the cartridge 5, activating a valve inside the cartridge 5 and allowing the composition to be dispensed into the bowl 12.

[0035] The ZPI mechanism can be a small magnet or other part capable of detecting position to ensure that the bowl is in the correct position before dispensing any composition. According to a preferred embodiment, a small magnet 20 acts as a position sensor in a fixed position (reading the ZPI or magnet when in close proximity). The software operating the HPD can record the tray position when the sensor makes contact and label it as position "zero" and use this as a reference so that the stepper motor 13 can perfectly position the tray to any target position for each composition dispensed. The tray 3 can also be removable and not fixed to the HPD so that it can be easily removed to switch compositions when in use. For example, a hair stylist can remove a tray holding oxidized HPC and replace it with another tray preloaded with semi-permanent (direct) dye (rather than removing each cartridge one by one).

[0036] Other components that provide structural support to the system of the present invention are the frame 4, the support 7, the mid-plate 11, and the bottom plate 28. Behind the frame 4 towards the rear of the housing is the speaker 16. The speaker 16, along with the microphone 19, operate the present invention through several audio functions. Voice command offers the hairstylist the advantage of controlling the present invention without using their hands and allows for increased multitasking, thus reducing the amount of time it takes for each client (which can take several hours for a hair coloring appointment). At the rear of the housing 1 is a battery pack 29 that is accessible through the rear of the housing and provides power to the entire system. According to a preferred embodiment, the battery pack 29 is removable and rechargeable, obtaining power through a detachable power cord, preferably USB-C or other standard format that can take a voltage input from 110-240V to allow international use of the battery pack 29.

[0037] 3 provides internal details of the HPD. According to a preferred embodiment of the present invention, contained within the frame 4, on the middle plate, or between the middle plate 11 and the bottom plate 28 are internal mechanisms including the cartridge RFID reader 15, rotary stepper motor 13 and other components. The rotary stepper motor 13, RFID reader 15, position sensor 20 and linear stepper motor 27 are located on top of the middle plate 11. Between the middle plate 11 and the bottom plate 28 are the controller 14, microphone 19, speaker 16, power button 17, power adapter (female) 18 and battery pack 29.

[0038] FIG. 4 illustrates various features of the dispensing tray. In accordance with a preferred embodiment of the present invention, the dispensing tray has five parts. The top of the dispensing tray is a plastic tray 22 that provides a surface on which the bowl 12 may rest. The surface of the plastic tray 22 includes openings to allow any potential spillage to be prevented from collecting on the bottom of the mixing bowl 12. In an alternative embodiment, the shape of the plastic tray 22 may be modified such that the sides of the tray curve upwards into a bowl shape to prevent excess spillage, and the bottom is solid plastic with no openings. Below the plastic tray 22 is a metal tray 23 and a bowl QR code reader (QR Code is a registered trademark) 26. Below the metal tray 23 and the QR code reader (QR Code is a registered trademark) 26 is a scale 25 that measures the weight of the compositions added to the bowl to provide the exact amount of each composition required. Below the scale 25 is a bottom metal tray 24. Together, these parts combine to form the tray on which the bowl 12 sits during the dispensing process.

[0039] 5A is a diagram of the dispensing mechanism. In accordance with a preferred embodiment of the present invention, the dispensing mechanism consists of the desired cartridge 5, the cap of the cartridge 6, a pin 31, and a linear stepper motor 27. The dispensing mechanism is attached to the intermediate plate 11. Once the hair stylist specifies the desired output from the present invention, the requested cartridge is selected and subjected to the dispensing process in the exact measurements required for the desired product. Once the correct cartridge 5 is in the correct dispensing position above the bowl 12, the magnet 21 of the linear stepper motor 27 is energized and pushes the pin 31 through a small opening into the cap 6 of the cartridge 5, activating a valve inside the cartridge 5 and allowing the composition to dispense into the bowl 12.

[0040] 5B and 5C depict the dispensing mechanism of the present invention in both a non-dispensing state (5B) and a dispensing state (5C). According to a preferred embodiment of the present invention, the dispensing mechanism (mounted to the intermediate plate 11) is in a non-dispensing state with the pin 31 in its rest position and therefore not activated by the linear stepper motor 27. Because the pin is not activated to push forward by the linear stepper motor, the cap 6 of the cartridge 5 remains closed and no product is dispensed. The control PCB 38 may include a microprocessor that interfaces with the linear stepper motor 27. If necessary, the PCB 38 and associated microprocessor transmit electrical energy to the linear stepper motor, which converts the circular motion into a linear motion that pushes the pin 31 forward and into the cap 6. When the cartridge needs to dispense product into bowl 12, linear stepper motor 27 activates pin 31, pushing pin 31 through a designated opening and into cartridge cap 6 where it pushes actuator 54, which opens the cartridge and dispenses product into bowl 12.

[0041] To dispense product from the cartridge, the linear stepper motor 27 converts electrical input from the PCB 38 into mechanical energy by generating a magnetic field that propels the pin 31 of the linear stepper motor 27 forward and into the cap 6. The pin 31 opens the valve by pushing a force direction 56 onto the pivot point 55 of the actuator 54. The actuator 54 converts the energy generated by the pin 31 into mechanical energy that opens the valve in the cap 6, thus dispensing the product from the cartridge 5 until the scale 25 or load cell 46 in the tray 3 reaches the desired weight of the product and the flow of electrical energy from the PCB 38 is turned off. If the RFID is not detected by the RFID reader 15 in the cap 6 of the cartridge 5 selected to dispense the product, the dispensing mechanism is not activated and the product is not released.

[0042] Figures 5D-H show the features of the mechanism involved in the dispensing of product from the HPC 5. According to a preferred embodiment of the invention, a live hinge based on a pivot point 55 combines with the design of the actuator 54 to convert the horizontal force applied by the pin 31 into a vertical force pushing on the stem of the cartridge 5. This then opens the valve and dispenses the product from the HPC 5. To ensure correct alignment, the carousel 3 uses a realignment system. After optical alignment has been achieved, if the pin 31 is not yet perfectly aligned with the actuator 54, the realignment system in the carousel 51 guides the pin 31 to the correct position in the cap 6, thus preventing the pin 31 from getting stuck in the cap 6.

[0043] Figures 6A-E show various angles of the inside and outside of the invention. According to a preferred embodiment of the invention, a lid 2 is attached to the top of the housing 1, and a plastic tray 22 is attached to the housing 1 at the bottom. On the front side of the invention, a logo lighting PCB 35 and an RFID reader 15 are placed and labeled as shown in Figure 6A. On top of the plastic tray 22, a bowl 12 can stay and its presence can be detected by a QR code reader (QR code is a registered trademark) 26. Inside the housing, a carousel of HPCs 5 is placed, which can be rotated to position the desired HPCs 5 in the dispensing position.

Also shown from this perspective is the base 25 of the present invention and the plastic tray 22 on which the bowl 12 sits. On the back side of the housing 1 is the battery pack 18. On the bottom of the present invention are the speaker 16 and the PCB 38.

[0045] FIG. 7 provides a detailed view of the invention. According to a preferred embodiment of the invention, the lid 2 is secured closed via a magnetic clasp 34. Any opening of the lid is detected by a lid opening sensor 33. The front facing portion of the housing 1 displays the logo of the invention and includes a logo illumination PCB 35. Located near the logo illumination PCB is an RFID reader 15. The housing 1 also comprises a high gloss panel 36 on which an LCD touch screen 9 is located. A QR code camera (QR Code is a registered trademark) 26 is located in a position that allows scanning of a QR code (registered trademark) located on the bowl 12. The invention may also be Bluetooth® capable via a Bluetooth® connectivity device (Bluetooth is a registered trademark) 37. The "brains" of the invention are contained within a "Main Printed Circuit Board ("PCB") 38 located near the rechargeable battery pack 29 and the Bluetooth® connectivity device (Bluetooth is a registered trademark) 37.

[0046] PCB 38 provides internet connectivity to the present invention and allows for the storage of data in an internal database, an external database, or a cloud database. Data such as customer reviews, previously mixed colors, and instruction inputs from the hair stylist are stored and referenced by the present invention to optimize the overall future experience for both the hair stylist and the customer. PCB 38 also allows the present invention to receive software updates as needed to improve the overall experience. Hair stylists can also remotely calibrate the present invention via an app or website profile connected to the present invention, as well as receive notifications and alerts related to the status of the present invention (such as low battery, low product amount, or other necessary messages).

[0047] The entire dispensing mechanism 39 is located centrally within the present invention as shown in the previous figures. An optical sensor 40 is located on the dispensing mechanism. A drip tray 41 collects any potential spills or leaks from the cartridge and prevents any damage to the mechanical system.

[0048] FIG. 8 is a detailed outline of the base assembly of the present invention. According to a preferred embodiment of the present invention, the base of the HPD includes several technical aspects such as a QR Code scanning camera (QR Code is a registered trademark) 26, a speaker 16, a camera PCB 42, a light sensor 45, and a control PCB 38. The QR Code scanning camera (QR Code is a registered trademark) 26 is embedded within the base of the present invention and scans the QR Code placed on the bowl associated with the present invention to ensure that the QR Code is in the correct location prior to dispensing any product. The use of the QR Code allows each bowl used to maintain its own function. For example, it may be useful to use one bowl for mixing lighter hair colors and another bowl for darker colors, or similarly, one bowl for permanent dye mixtures and another bowl for semi-permanent or semi-permanent hair dyes. In this way, the use of the QR Code allows hair stylists to utilize a unique organization and categorization system for mixed dyes. The Camera PCB 42 may connect to and share data with the Control PCB 38 regarding the QR code that is scanned. For example, a hair stylist may have a unique bowl for each customer. By sharing data regarding the customer and their unique bowl, the Camera PCB 42 may determine what colors to mix based on the QR code that is scanned (because the QR code is associated with a particular customer's data).

[0049] The speaker 16, when enabled, allows the present invention to interact with voice commands and provide alert and notification sounds. The light sensor 45 adjusts the illumination of the logo on the front facing portion of the present invention, as well as providing the ability to dim the light, as well as have several light colors, patterns or brightness indicate various states of the present invention. The base of the present invention is also assembled with several necessary structural parts that allow the mechanical system to function, such as the hex adapter 43, bearings 44 and bottom tray assembly 10. The hex adapter 43 and bearings 44 aid in the rotation of the carousel 51, allowing for a smooth pivot each time a new cartridge is selected to be dispensed.

[0050] Figures 9A-J display the exterior surface of the present invention from all angles. According to a preferred embodiment of the present invention, the base of the present invention can be separated from the housing 1 for general maintenance. The lid 2 can open and remain attached to the housing 1 by a hinge 30 to allow easy access to the cartridge for maintenance and replacement of the cartridge. Figures 9A-D provide bottom views of the housing and base of the present invention. Figure 9B provides a bottom overall view of the base. Figures 9A and 9C provide backside views and Figure 9D provides a front facing view. Figures 9E-G provide direct rear, profile and front views of the housing 1. Figure 9H provides a bird's-eye view of the lid 2 of the present invention. Figures 9J-I provide a top-down view of the housing 1.

[0051] 10A is a cross-sectional view of the present invention along plane A. According to a preferred embodiment of the present invention, a hex drive 52 is implemented with a stepper motor 13, an actuator sensor 48 and a linear motor 47 to rotate the carousel 51 and dispense the contents of the cartridges. The actuator sensor 48 converts electrical energy provided by a power PCB 49 into physical energy that is generated through the linear motor 47, which converts horizontal motion into vertical motion to open the cap 6 of the desired cartridge 5. To position the desired cartridge at the dispense position, the stepper motor 13 rotates the carousel 51 with assistance from the hex drive 52 and bearings 44. To ensure that the cartridges in use are associated with the present invention, an RFID reader 15 is positioned to scan each cartridge as it passes the dispense position.

[0052] Located within the bottom tray assembly 10 and beneath the plastic tray 22 is a load cell 46 or scale 25 that measures the mechanical force of the bowl that collects the dispensed product and converts it to weight for accurate measurement of each composition. Behind the front facing portion of the housing 1 is a light PCB 50 that provides power to the LED lights found behind the translucent logo design and light sensor 45. On the back side of the housing 1, a power switch or button 17 is located near the power PCB 49, battery pack 29 and control PCB 38. All power related mechanical features are conveniently located on the bottom behind the dispensing area where they are easily accessed once the base of the present invention is removed from the outer housing 1.

[0053] Figure 10B is a cross-sectional view of the invention along plane B with detail image C. According to a preferred embodiment of the invention, cartridges 5 are loaded into the invention from the top when lid 2 is opened. These cartridges are arranged in a circle so that they can rotate in carousel 51 for positioning in a dispensing position above a bowl placed in the open space above bottom tray assembly 10 seen in cross-section BB of Figure 10B. The dispensing mechanism is shown in detail C. This mechanism includes stepper motor 13, linear motor 47, hex drive 52, hex adapter 43, pins 31, RFID inclusion cap 6, cartridge 5, RFID reader 15, linear stepper motor 27, pins 31, actuator 54 and control PCB 38.

[0054] 11 is a cross-sectional view of the RFID containment cap 6 and cartridge 5 associated with the present invention along plane A with detail image B. In accordance with a preferred embodiment of the present invention, each cartridge 5 and its associated RFID containment cap 6 is unique in relation to the present invention; that is, any cartridge can be used in place of one associated with the present invention by virtue of the RFID containment cap and RFID reader located within the present invention. Additionally, the RFID associated with each cartridge acts as a label of the product contained within the cartridge to ensure that the correct product is dispensed. If the cartridge is low in product, this is communicated to the PCB 38 via the RFID associated with the low volume cartridge.

[0055] To dispense product from the cartridge, the PCB 38 receives commands from the hairstylist, either input directly to the invention from the hairstylist's wireless device or transmitted via Bluetooth or cloud software. When the bowl 12 is detected by the QR code scanning camera (QR code is a trademark) 26 at the dispensing location, the PCB sends current to the linear stepper motor 27 adjacent to the cap 6. The linear stepper motor 27 converts electrical input into mechanical energy by generating a magnetic field, which propels the pin 31 of the linear stepper motor 27 forward and into the cap 6. The pin opens the valve by pushing a force 56 onto the pivot point 55 of the actuator 54. The actuator 54 converts the energy generated by the pin 31 into mechanical energy that opens the valve in the cap 6, thus dispensing product from the cartridge 5 until the scale 25 or load cell 46 in the tray 3 reaches the desired weight of product and the flow of electrical energy from the PCB 38 is turned off. If the RFID is not detected by the RFID reader 15 in the cap 6 of the cartridge 5 selected to dispense product, the dispensing mechanism will not activate and no product will be released.

[0056] 12A-E show a carousel containing an HPC in various positions relative to the housing. According to a preferred embodiment of the invention, the HPC 5 is fixed on a carousel 51 that can be rotated to position the correct HPC 5 in the dispense position. The carousel 51 containing the cartridge 5 is removable from the housing 1 and can be lifted by its handle from the top of the housing 1 when the lid 2 is in the open position. FIG. 12A shows the carousel 51 containing the HPC 5 as it appears fully removed from the housing 1 of the invention. FIG. 12B shows the carousel 51 relative to the housing 1 and the lid 2. FIG. 12C shows the carousel 51 as it is removed from or inserted into the housing 1. FIG. 12D provides an alternative view of the carousel 51 as it is removed from or inserted into the housing 1. In FIG. 12E, the handle of the carousel 51 can be seen in the center of the circle of the HPC 5. This handle allows the carousel 51 to be easily removed from and inserted into the housing 1. Beneath the handle of the carousel 51 is a hex drive 52 which is one piece of the mechanism involved in rotating the carousel 51 .

[0057] 13A-B show the features of the mechanism involved in rotating the carousel. In accordance with a preferred embodiment of the present invention, the center of the carousel 51 contains a rotation mechanism comprising a hex drive 52, bearings 44, and a stepper motor 13. The stepper motor 13 is activated upon receiving an electrical signal from at least one of the PCBs. The stepper motor 13 is then forced upwards into the opening of the hex drive 52, causing the hex drive 52 to rotate, thereby rotating the carousel 51. The mechanism is held in place by the bearings 44. The curved smooth keyed design of the hex drive 52 facilitates proper positioning of the carousel 51, as the matching carousel key is guided into position to allow for a given initial tolerance. The compact size and shape of the carousel 51 and housing 1 prevent potential misalignment with the hex drive 52. FIG. 12A shows the stepper motor 13 in a pivoted position inserted into the hex drive 52. FIG. 12B shows the stepper motor 13 in a non-mated position, not engaged with the hex drive 52.

[0058] 14A-B show the realignment mechanism of the carousel. According to a preferred embodiment of the present invention, the carousel 51 includes a realignment section that allows the pins 31 to be perfectly aligned with the caps 6 of the cartridges 5 so that the pins 31 can open the valves that release the product from the cartridges without the product getting stuck in the caps 6. The pins 31 are pushed precisely forward by a linear stepper motor 27 that can control the speed at which the pins 31 are pushed into the caps 6. When the realignment section of the carousel 51 does not detect that the pins 31 and the caps 6 are perfectly aligned, the linear stepper motor is not engaged and the pins are not pushed forward until the correct alignment is achieved. If the alignment is off, the stepper motor 13, which rotates the carousel via the hex drive 52, continues to rotate the carousel in small increments until alignment is detected. FIG. 14A shows a bottom-up view of the carousel 51, the caps 6 of the cartridges 5, the pivot mechanism including the stepper motor 13, the hex drive 52 and the bearings 44. FIG. 14B shows a close-up view of cap 6 in the realignment section of carousel 51 with pins 31 aligned with cap 6 for dispensing.
