DETAILED DESCRIPTION
[0036] While the specification concludes with claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the drawing figures, in which like reference numerals are carried forward. It is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms.
[0037] The present invention provides a novel and efficient hygienic device that uses proprietary sonic technology to aid in the cleansing and prevention of surface deposits on contact lenses (e.g., soft hydrogel, silicone hydrogel, hybrid, hard/RGP, colored, etc.). Embodiments of the invention provide a vibrating base assembly that is operably configured to be used in combination with contact lens cases as part of lens wearers' hygienic routine to beneficially reduce damage caused by the excessive use of rubbing fingertips when cleaning contact lenses. In addition, embodiments of the invention provide two different cleaning modes for selection by a user, namely, a “sleep” mode and a “fast” mode, which can be selectively activated based on the needs and preferences of the user. As used herein, the terms “sleep” mode and “fast” mode are meant only to identify the varying modes and are not to be construed as limiting in any way. Embodiments of the present invention also provide an assembly that can operate without the generation or output of excessive noise, i.e., an assembly that operates quietly, and that can operate without the need for additional external components, e.g., assemblies, connectors, external power sources, etc. The present invention is operably configured to come into direct contact with the contact lens case or container, not the contact lenses themselves as is the case with some prior art, which prevents the lenses from being exposed to dirt, dust, rust, germs, and other foreign particles that may be resident on the assembly itself.

[0039] The base housing 102 comprises the at least one vibration motor 302, 304 (i.e., one or more than one) and, in an exemplary embodiment, comprises two (2) Eccentric Rotating Mass vibration motors (ERMs). Exemplary vibration motors 302, 304 consist of 2 3 VDC motors producing between 1200 and 1600 revolutions per minute (RPM), a voltage of approximately 1-1.5V, having wire leads and an operating temperature of approximately −20° C.˜70° C., and being used for vibration alerting and haptic feedback. The vibration motors 302, 304 are suitable for single/double cell power buses of Alkaline, Zinc, Silver Oxide and single cell Lithium primary sources, NiCd, NiMH, and Li-ion secondary rechargeable batteries. The at least one vibration motor 302, 304 is electrically coupled to a power source 306, and operably configured to selectively induce a vibration therefrom with at least one switch 106 coupled to the base housing 102. In one embodiment, the base housing 102 is formed with two shell members operably configured to couple together around a perimeter edge or surface thereon to form the housing cavity 300 and one or more enclosed aperture(s) for the switch(es) 106 and an enclosed aperture for an upper support wall 112.
[0040] Beneficially, the vibration motors 302, 304 overcome the known limitations of the heretofore-known devices and methods of this general type by operating in a much quieter fashion that is not excessively disturbing or bothersome to those in close proximity to the assembly 100. In one embodiment, the power source 306 is a USB-C charging port (seen in
[0041] It should be understood that terms such as, “front,” “rear,” “side,” top,” “bottom,” and the like are indicated from the reference point of a viewer viewing the base housing 102 from the front thereof (see
[0042] The assembly 100 also includes a bottom surface 700 (as best depicted in
[0043] The assembly 100 may further comprise at least one support pad 308 (depicted in
[0044] As best depicted in
[0045] In accordance with another feature of the present invention, the assembly 100 may also include an internal support member 314 retaining the at least one vibration motor 302, 304, wherein the at least one vibration motor 302, 304 is adjacent and below (and may support) the bottom wall portion 116. As used herein, “adjacent” is defined as directly touching or within 0.5 inches of the bottom wall portion 116. The internal support member 314 is designed to structurally support or protect the at least one vibration motor 302, 304 from damage or injury caused by external forces. The at least one vibration motor 302, 304 is approximately between 2 mm and 6 mm, although it may be slightly larger when encapsulated in the internal support member 314.
[0046] Referring now to
[0047] In an exemplary embodiment, the assembly 100 comprises two vibration motors 302, 304 with one of the two vibration motors 302, 304 disposed adjacent and below the bottom wall portion 116 of each of the two defined circular portions 206, 208. As used herein, “adjacent” is defined as directly touching or within 0.5 inches of the bottom wall portion 116 of each of the two defined circular portions 206, 208. This placement and configuration beneficially improves the efficiency and effectiveness of the cleaning of the contact lenses. The close proximity between the two vibration motors 302, 304 and the two defined circular portions 206, 208 results in a more effective sanitation and cleaning of the contact lenses housed within the contact lens containers because the frequency of the vibration generated by the two vibration motors 302, 304 is greater closer to the source, i.e., to the two vibration motors 302, 304. As such, the greater frequency near the contact lens containers increases the vibration of the contact lens solution within the contact lens containers and the contact lenses housed therein, resulting in a continued vibration that stimulates the back-and-forth movement of the contact lenses against the contact lens solution. This movement mimics the rubbing of a user's fingertips on contact lenses and the resulting removal of residue from the lenses, but eliminates and prevents the damage that is often caused to the contact lenses by the excessive use of rubbing fingertips. In this way, placement of the two vibration motors 302, 304 adjacent and below the bottom wall portion 116 of each of the two defined circular portions 206, 208 (wherein the two defined circular portions support two contact lens containers 500, 502) significantly contributes to the effectiveness of the cleaning function performed by the assembly 100.
[0048] The assembly 100 may also include a first side retention member 118 protruding from the sidewall portion 114 on one of the two defined circular portions 206, 208 and of the friction-inducing, deformable, and polymeric material; and a second side retention member 120 opposing the first side retention member 118 protruding from the sidewall portion 114 on another of the two defined circular portions 206, 208 and of the friction-inducing, deformable, and polymeric material. The two retention members 118, 120 are deformable in that they are capable of being repeatedly manipulated without tearing and are friction-inducing to beneficially aid in the cleaning function of the assembly 100 and to keep and compressively retain the two contact lens containers 500, 502 substantially in a stationary location within the two defined circular portions 206, 208 during use of the assembly 100.
[0049] In an exemplary embodiment of the present invention, the side retention members 118, 120 are substantially thin, narrow, discontinuous, and have rounded edges. As used herein, “discontinuous” is defined as not completely surrounding or connecting at a point. As mentioned above, the friction-inducing material may include organic and non-organic substances such as resin, ceramics, fibers, and metals. In an exemplary embodiment, the friction-inducing material is a natural rubber, chloroprene, polysiloxane, nitrile butadiene rubber (NBR), ethylene propylene diene monomer (EPDM), styrene-butadiene rubber (SBR), isobutylene isoprene, fluorosilicone rubber, or another elastomer having a high coefficient of friction with respect to other contact materials (friction coefficient ranging between 1.0 and 4.0). In alternate embodiments, the assembly 100 may comprise only a single side retention member 118.
[0050] Similarly, the assembly 100 may also include at least one floor retention member 122 protruding from the bottom wall portion 116 on and centrally disposed on one of the two defined circular portions 206, 208, partially surrounded by the first side retention member 118, and of the friction-inducing, deformable, and polymeric material; and at least one floor retention member 124 protruding from the bottom wall portion 116 on and centrally disposed on another of the two defined circular portions 206, 208, partially surrounded by the second side retention member 120, and of the friction-inducing, deformable, and polymeric material. The floor retention members 122, 124 are operably configured to serve the same functions as the side retention members 118, 120 and, in one embodiment, embody the same dimensions, properties, and characteristics as the side retention members 118, 120. In alternate embodiments, the assembly 100 may comprise only a single floor retention member 122 or may comprise at least one floor retention member 122 in conjunction with at least one side retention member 118.
[0051] As seen in
[0052] In accordance with a further feature, the assembly 100 includes an electronic controller 316 electrically coupled to the power source 306 and communicatively coupled to the at least one vibration motor 302, 304. The electronic controller 316 may comprise an electronic screen or at least one button which may be selectively manipulated by a user to control the power source 306, e.g., to turn the assembly 100 on or off, and to control the at least one vibration motor 302, 304, e.g., to select the specific operation mode desired by the user. The electronic controller 316 may communicate with the at least one vibration motor 302, 304 over a network 1200 using a short-range communication protocol, for example, a Bluetooth communication protocol, which may also operate as a receiver, transmitter, and/or transceiver. The PAN interface may permit the electronic controller 316 to connect wirelessly to another electronic computing device, e.g., software or mobile application, via a peer-to-peer connection or other communicatively coupled configuration. The network interface(s) may also include a local area network (LAN) interface. The LAN interface may be, for example, an interface to a wireless LAN, such as a Wi-Fi network. In one embodiment, there is a wireless LAN that provides the electronic controller 316 with access to the Internet for receiving and sending inputs/messages to, for example, an administrator server or other electronic device over, for example, the Internet. The range of the LAN interface may generally exceed the range available via the PAN interface. Typically, a connection between two electronic devices via the LAN interface may involve communication through a network router or other intermediary device. Additionally, the network interface(s) may include the capability to connect to a wide area network (WAN) via a WAN interface. The WAN interface may permit a connection to a cellular mobile communications network. The WAN interface may include communications circuitry, such as an antenna coupled to a radio circuit having a transceiver for transmitting and receiving radio signals via the antenna. The radio circuit may be configured to operate in a mobile communications network, including but not limited to global systems for mobile communications (GSM), code division multiple access (CDMA), wideband CDMA (WCDMA), and the like.
[0053] The assembly 100 also features two modes of operation, namely, a “sleep” mode and a “fast” mode, which the user may select based on user needs and preferences. Specifically, in accordance with an exemplary embodiment, the assembly 100 comprises at least two switches 106a, 106b translatably coupled to the base housing 102, wherein one of the at least two switches 106a is operably configured to induce the vibration from the at least one vibration motor 302, 304 in a first mode with a constant vibration for a first mode period of time and a first mode vibrational rotations per minute and another of the at least two switches 106b is operably configured to induce the vibration from the at least one vibration motor 302, 304 in a second mode with a cyclic constant vibration for a second mode period of time and a second mode vibrational rotations per minute, wherein the first mode vibrational rotations per minute is less than the second mode vibrational rotations per minute. As used herein, the “sleep” mode corresponds to the first mode and the “fast” mode corresponds to the second mode. The first mode (interchangeably referred to herein as the “sleep” mode) is operably configured to be used once a day, before the user goes to sleep, to allow for cleaning of the contact lenses throughout the night when they are typically not in use. It provides a gentle, overnight, intermittent lens cleaning. The first mode functions on a 12-hour sleep cycle and performs 3 cycles per hour for a combined total of 36 cycles in 12 hours. The vibration motors 302, 304 vibrate at 1,200 RPM for 60 seconds, stop after 60 seconds, and resume again after 20 minutes. Said differently, the vibration motors 302, 304 vibrate for 60 seconds every 20 minutes. In one embodiment, the progress of the two modes of operation is indicated by an audio or visual indicator emanating from the switches 106a, 106b, e.g., by a light or tone. Under the first mode, the indicator light emanating from the switch 106a dims to 50% after the first 60 seconds of running. If the switch 106a is not activated or pressed, the cycle automatically ends after 12 hour cycle and the indicator light dims completely to 0%. If the switch 106a is not activated or pressed during the cycle, the cycle ends and the indicator light dims completely to 0%.
[0054] The second mode (interchangeably referred to herein as the “fast” mode) is operably configured to provide a faster cleaning of the contact lenses than the first mode, which is accomplished by the greater vibrational rotations per minute produced under the second mode than under the first mode. This second mode of operation is ideal when contact lenses need to be cleaned in a shorter period of time, but this second mode of operation should preferably be used no more than once a day. The second mode functions on a 3-minute cycle and performs one uninterrupted 3-minute cycle. When the switch 106b is activated or pressed once, the indicator light emanating from the switch 106b turns on at 100% brightness and remains blinking (at 0.5-seconds frequency) during the duration of the 3-minute cycle. The vibration motors 302, 304 vibrate at 1,600 RPM FOR 3 minutes and shut off automatically at the conclusion of the cycle. When the switch 106b is activated or pressed a second time, the assembly 100 is shut off.
[0055] Before activating either mode of operation, the contact lenses must be placed within the contact lens containers 500, 502 along with fresh contact lens solution, e.g., cleaning solution, multi-rinse solution, multipurpose solution, etc., and the contact lens containers 500, 502 are then placed within the two defined circular portions 206, 208. Without the contact lens solution, the vibration generated by the at least one vibration motor 302, 304 may cause damage, e.g., tearing, scratching, etc., to the contact lenses rather than effectively clean the contact lenses as is intended. As such, each contact lens must rest within approximately 2.5 mL of contact lens solution. For adequate rubbing and rinsing, approximately 5 mL of solution (2.5 mL/lens) should be used. The average contact lens container 500, 502 holds approximately 2.5 mL of solution, the amount necessary to properly disinfect the contact lens.
[0056] An improvement has also been disclosed that is designed to be used in combination with the pair of contact lens containers 500, 502 having a lens base 504 and a lens cap 506 selectively removably coupled to the lens base 506. The lens base 504 and the lens cap 506 are best seen in
[0057] In one embodiment, the bottom wall portion 116 defines a portion of the upper surface 104 and defines the lens support plane 310 parallel and non co-planar with the base support plane 312 defined by the bottom surface 700. The lens support plane 310 is operably configured to provide an adequate support surface for retention of the pair of contact lens containers 500, 502. The base support plane 312 is operably configured to provide a stable bottom surface for the base housing 102 of the assembly 100 to rest on.
[0058] The improvement may also include the at least one support pad 308 of a friction-inducing, deformable, and polymeric material and at least partially defining the bottom surface 700 of the vibrating base assembly 100. As explained in greater detail above, the support pad 308 is operably configured to generate friction between the assembly 100 and the surface on which it is laid to rest to beneficially avoid the assembly 100 from inadvertently sliding, slipping, or falling.
[0059] In accordance with a further feature, the assembly 100 includes the internal support member 314 retaining the at least one vibration motor 302, 304 to house, shield, and protect the at least one vibration motor 302, 304 from damage caused by external forces.
[0060] The sidewall portion 114 may further include the at least one arcuate portion 200 defining, with an opposing surface of the sidewall portion 202, the central width 204, and defining two defined circular portions 206, 208 partially defined with the at least one arcuate portion 200 interposed thereon, the two defined circular portions configured to support the at least one contact lens container 500.
[0061] In an alternate embodiment of the present invention, the assembly 100 comprises at least one of the first side retention member 118 protruding from the sidewall portion 114 and of the friction-inducing, deformable, and polymeric material; the second side retention member 120 opposing the first side retention member 118 protruding from the sidewall portion 114 and of the friction-inducing, deformable, and polymeric material; the floor retention member 122 protruding from the bottom wall portion 116 and of the friction-inducing, deformable, and polymeric material; or the floor retention member 124 protruding from the bottom wall portion 116 and of the friction-inducing, deformable, and polymeric material. Said differently, the assembly may include one, some, or all of the first side retention member 118, the second side retention member 120, the floor retention member 122, or the floor retention member 124, all of which perform a similar function, namely, retaining the pair of contact lens containers 500, 502 within the two defined circular portions 206, 208 and maintaining the pair of contact lens containers 500, 502 in a substantially stationary position during use of the assembly 100.
[0062] The improvement also includes the electronic controller 316 electrically coupled to the power source 306 and communicatively coupled to the at least one vibration motor 302, 304; and the at least one switch translatably coupled to the base housing 102, wherein the at least one switch is operably configured to induce the vibration from the at least one vibration motor 302, 304 in a first mode with a constant vibration for a first mode period of time and a first mode vibrational rotations per minute. Said differently, the at least one switch may be operably configured to generate a first mode vibrational rotations per minute, a second mode vibrational rotations per minute, or both a first and a second mode vibrational rotations per minute. In a preferred embodiment, the assembly 100 comprises two modes of operation, namely, a first and a second mode, to beneficially provide the user with more personalized vibrational modes of operation designed to address different user needs. In an alternate embodiment, however, the assembly 100 may only comprise a single mode of operation, i.e., a first or a second mode, to address a specific and targeted user need.
