The present disclosure relates to a shaving razor having a cartridge containing one or more blades. More particularly, the present disclosure relates to a system and method for determining accumulation of debris in the cartridge.
A user of a shaving razor is faced with the problem of determining when too much debris has accumulated around one or more blade(s) in a razor cartridge, e.g., in the space between two adjacent blades or the space between the blades and the guard bar and/or the lubricating strip. However, it is difficult for a user to objectively determine precise level(s) of accumulation of debris in the cartridge and/or around one or more blades(s), and the user needs to rely on visual observation and/or on subjective feeling of how effective the cartridge and/or the blade is for shaving, neither of which provides an accurate, objective assessment of how much debris has accumulated. Even if a user attempts to rinse the razor cartridge with running water, it is not readily apparent to the user how effective the rinsing is after a period of time. Therefore, there is a need for a system and a method for at least (i) objectively determining precise level(s) of accumulation of debris in the cartridge and/or around one or more blades(s), and (ii) notifying a user when to rinse the cartridge and/or the blade(s), which system and method eliminate the guesswork now required.
The present disclosure provides a system and a method to objectively determine one or more level(s) of accumulation of debris in a shaving cartridge and/or around one or more blades(s) of the shaving cartridge.
The present disclosure also provides a system and a method to objectively determine one or more level(s) of accumulation of debris in a shaving cartridge and/or around one or more blades(s) of the shaving cartridge by using a light-based detection system, e.g., an infrared (IR) light detection system.
The present disclosure further provides a system and a method to objectively determine one or more level(s) of accumulation of debris in a shaving cartridge and/or around one or more blades(s) of the shaving cartridge by using a light-based detection system provided in or on the shaving cartridge and/or a handle of the shaving razor.
The present disclosure still further provides a system and a method to objectively determine one or more level(s) of accumulation of debris in a shaving cartridge and/or around one or more blades(s) of the shaving cartridge by using a light-based detection system provided in or on a base unit or module that is distinct from the shaving cartridge and/or a handle of the shaving razor.
The present disclosure also provides a system and a method to objectively determine one or more level(s) of accumulation of debris in a shaving cartridge and/or around one or more blades(s) of the shaving cartridge and notify a user of the cartridge regarding the determined level(s) of accumulation of debris.
The present disclosure further provides a notification unit comprising at least one of (i) a light indication unit configured to output information regarding the determined level of accumulation of debris, (ii) an aural indication unit configured to output information regarding the determined level of accumulation of debris, and (iii) a haptic indication unit configured to output information regarding the determined level of accumulation of debris. In this manner, the user will objectively know the level of accumulation of debris.
The present disclosure still further provides a notification unit comprising at least one of (i) a light indication unit configured to output information regarding when to rinse the shaving cartridge, (ii) an aural indication unit configured to output information when to rinse the shaving cartridge, and (iii) a haptic indication unit configured to output information regarding when to rinse the shaving cartridge.
The present disclosure yet further provides a system and a method to objectively determine one or more level(s) of accumulation of debris in a shaving cartridge and/or around one or more blades(s) of the shaving cartridge so that information regarding the determined level of debris accumulation can be cumulatively collected, stored, and/or analyzed by a control and/or analysis unit to determine how quickly debris accumulates and/or how frequently the razor needs to be rinsed for a particular user.
A component or a feature that is common to more than one drawing is indicated with the same reference number in each of the drawings.
Referring to the drawings and, in particular to
Referring to
In this example, retainers 200 extend along a length L on side edges 105 and 107 of about 8.5 mm, for example. However, it should be appreciated that retainers 200 can extend along a shorter or longer portion of side edges 105 and 107. For example, a pair of retainers 200 can each extend along the entire length, a shorter portion, or a longer portion of side edges 105 and 107. Such extensions can secure in place a guard bar, a cap element, or a trimmer assembly, for example. In addition, as noted above, any number of retainers can be used with shaving cartridge 100. For example, a single retainer or four retainers can be used to retain the position of blades 117 in the housing.
When shaving cartridge 100 having at least one blade 117 provided between guard bar 113 adjacent to front edge 101 of the housing and cap 115 adjacent to rear edge 103 of the housing is used for shaving, the region surrounding the at least one blade 117, e.g., (i) a region between the at least one blade 117 and at least one of guard bar 113 and cap 115, or (ii) a region between the at least one blade 117 and at least one more blade 117 (if two or more blades 117 are provided), is subjected to debris accumulation, e.g., hair, residuals of products for the shaving preparation (e.g. shaving cream, shaving foam, shaving gel, shaving oil etc.), dead skin cells and/or lubricant emitted from a lubrication element provided on shaving cartridge 100. According to the present disclosure, systems and methods are provided to advantageously implement (i) objective determination of multiple levels of debris accumulation, and (ii) provide notifications to the user regarding the multiple levels of wear, and (iii) provide notifications to the user when to rinse shaving cartridge 100 and/or the at least one blade 117. The level of debris accumulation can be determined in several ways.
In one example method, an amount of debris accumulation in a region surrounding the at least one blade 117, e.g., (i) a region between the at least one blade 117 and at least one of guard bar 113 and cap 115, or (ii) a region between the at least one blade 117 and at least one more blade 117 (if two or more blades 117 are provided), can be detected by a sensor based on an amount of IR light reflected by the region surrounding the at least one blade 117 and detected by the sensor. By comparing the detected amount of IR light reflected by the region surrounding the at least one blade 117 to one or more predefined reference thresholds, one or more levels of debris accumulation can be detected by the sensor.
In one embodiment, a light sensor, e.g., an IR light sensor of the type described in connection with
Razor 1, illustrated in
Control unit 6004 receives and processes the information output from light sensor 6001 and/or image sensor 6002 to determine the level of debris accumulation in a region surrounding the at least one blade 117, e.g., region 1171 and/or region 1172. For example, control unit 6004 can compare the detected amount of light (e.g., IR light) reflected by region 1171 and/or region 1172 to a reference threshold level of light. Control unit 6004 can determine the level of debris accumulation based on an amount of deviation of the detected amount of reflected light from the reference threshold level(s) of reflected light. For example, a first reference threshold level of reflected light may correspond to a completely debris-free condition of region 1171 and/or region 1172. For the purposes of this example, it will be assumed that a completely debris-free condition corresponds to a condition in which the light emitted by sensor 6001 is reflected by a light-color object (e.g., the condition depicted in
Alternatively, or in addition, control unit 6004 can analyze the detected image (as detected by image sensor 6002) of region 1171 and/or region 1172, and by comparing the amount of debris accumulation shown in the detected image to one or more predefined reference levels of debris accumulation, control unit 6004 can determine the level of debris accumulation based on an amount of deviation of the debris accumulation shown in the detected image to one or more predefined reference threshold level(s) of debris accumulation. For example, a first reference threshold level may correspond to a completely debris-free condition of region 1171 and/or region 1172. A second reference threshold level may correspond to 33% of region 1171 and/or region 1172 filled with debris. A third reference threshold level may correspond to 66% of region 1171 and/or region 1172 filled with debris. A fourth reference threshold level may correspond to a completely debris-filled condition of region 1171 and/or region 1172. These examples are not limiting.
Control unit 6004 can provide information regarding the determined level of debris accumulation in a region surrounding the at least one blade 117 to notification unit 6003a, which in turn can generate output signal(s) corresponding to the determined level(s) of debris accumulation by at least one of (i) a light indication (e.g., using different colored LED lights), (ii) an aural indication (e.g., using different sound levels and/or patterns), and/or (iii) a haptic indication (e.g., using different haptic intensity and/or patterns). In an example embodiment, each of these forms of indication can indicate, e.g., three different levels of debris accumulation: a first level corresponding to 0-33% debris accumulation of region 1171 and/or region 1172; a second level corresponding to 34-66% debris accumulation of region 1171 and/or region 1172; and a third level corresponding to 67-100% debris accumulation of region 1171 and/or region 1172. In this example embodiment, either the indication corresponding to the second level of debris accumulation or the indication corresponding to the third level of debris accumulation can be used as an indication to the user of shaving cartridge 100 to rinse the cartridge. In an alternative example embodiment, a single ON/OFF “rinse” indication can be provided, either in addition to, or alternatively to, the above-described three different levels of debris accumulation, using the at least one of the light, aural and haptic indication. In this alternative example, a level of debris accumulation corresponding to 50-100% debris accumulation of region 1171 and/or region 1172 would be indicated by the “rinse” indication being turned ON. These examples are not limiting.
Control unit 6004 can cumulatively collect and/or store the information regarding the determined level of debris accumulation to analyze and determine the rate of debris accumulation. In addition, control unit 6004 can analyze the rate of debris accumulation in conjunction with data provided by a user or data from a database regarding particular skin properties and/or hair properties, thereby enabling customized analysis and data collection of an individual user's razor use.
The information output from light sensor 6001 and image sensor 6002, and/or the information regarding the determined level of debris accumulation in an area surrounding the at least one blade 117, can be transmitted (i) wirelessly via the transceiver 6007a or (ii) via a wired connection through interface unit 6006a for external power/data connection, to base module or unit 6020 which is external to razor 1. As shown in
Base module or unit 6020 can be used in conjunction with razor 1 in multiple ways. In a first example, information received (e.g., via a hard-wired connection through interface 6006b or wirelessly via transceiver 6007b) from razor 1 (e.g., information output from light sensor 6001 and/or image sensor 6002, and/or the information regarding the determined level of debris accumulation in an area surrounding the at least one blade) can be used, e.g., by base control unit circuitry 6021, to indicate the determined level of debris accumulation by an output via notification unit 6003b.
In a second example, information received (e.g., via a hard-wired connection through interface 6006b or wirelessly via transceiver 6007b) from razor 1 (e.g., information output from light sensor 6001 and/or image sensor 6002, and/or the information regarding the determined level of debris accumulation in an area surrounding the at least one blade) can be cumulatively collected, stored, and/or analyzed by base control unit circuitry 6021 of base module or unit 6020 to determine the rate of debris accumulation for shaving cartridge 100 and/or the at least one blade 117 so as to require rinsing. In addition, base control unit circuitry 6021 of base module or unit 6020 can analyze the rate of debris accumulation in conjunction with data provided by a user or data from a database regarding particular skin properties and/or hair properties, thereby enabling customized analysis and/or data collection of an individual user's razor use.
In a third example, base module or unit 6020 can be used to make the light detection and/or the image detection directly, instead of the light detection and/or the image detection being performed by the components of razor 1. For the direct measurement by base module or unit 6020, shaving cartridge 100 is placed in cradle area 602 of base module or unit 6020. In one example embodiment, retainers 200 of shaving cartridge 100 can be placed in electrical contact with contact pins 6022 of base unit or module 6020, thereby enabling detection of the presence of shaving cartridge 100 in cradle 602. Light sensor 6001 of base module or unit 6020 detects the reflected light (in the case of light sensor 6001) from region 1171 and/or region 1172 of shaving cartridge 100, and/or image sensor 6002 of base module or unit 6020 detects the image of region 1171 and/or region 1172, as described above in connection with light sensor 6001 and image sensor 6002 provided in razor 1. Base control unit circuitry 6021 can process and compare the detected reflected light level and/or the detected image to the specified reference threshold level(s) to determine the level of debris accumulation in region 1171 and/or region 1172, and the determined level of debris accumulation can be indicated by an output via notification unit 6003b, as discussed above in connection with the corresponding processing performed in razor 1.
