The disclosed embodiments relate generally to magnetic housings for electronics, including, but not limited to, magnetic housings configured for wireless communication.
Many portable electronic devices (e.g., as mobile phones, audio players, video players, etc.) generate audio output. To maintain privacy (e.g., for phone calls, etc.) and/or to improve user experience (e.g., for music and/or video playback, for noisy environments, etc.), a user may choose to use headphones. Although some portable electronic devices support wireless headphones that receive audio signals wirelessly (e.g., Bluetooth, etc.), many users of electronic devices still use wired headphones that receive audio signals through an audio cord connected to an audio port of the portable electronic device. Unfortunately, wired headphones can become easily tangled when the portable electronic device is not being used. For example, the cord of the wired headphone may become tangled when the portable electronic device is stored in a bag or a purse. Similarly, other electronic devices may use video cables, audio cables, and/or power cords that present similar cord management issues to the user.
One solution to this problem is to detach the cord of the wired headphone from the portable electronic device and to store the wired headphones separately. For example, the wired headphones may be stored in a special pouch or container. Similarly, the cord of the wired headphones may be wrapped around itself so that the cord does not become tangled. However, detaching the cord from the portable electronic device is cumbersome because the cord must be reattached (and possibly removed from a container or unwound) prior to being able to use the wired headphones with the portable electronic device. Furthermore, the headphones may become lost or may be forgotten if the headphones are detached from the portable electronic device.
Another solution to this problem is to wrap the cord of the wired headphones around the portable electronic device without detaching the cord from the portable electronic device. However, the cord of the wired headphone may become unwrapped and tangled. Furthermore, although the cord may be organized when it is wrapped around the portable electronic device, once the cord is detached from the portable electronic device, the cord may become unwrapped.
Thus, a cord management system that solves the aforementioned problems is desirable.
Some embodiments provide a case for an object. The ease has a front, a back, a bottom, a top, a first side, and a second side. In some embodiments, substantially all of the case is made of magnetic material.
In some embodiments, the magnetic material is magnetic metal, such as SAE 1008 steel; an alloy of iron, cobalt, and/or nickel; and/or SAE Type 416 stainless steel.
In some embodiments, the case has a bumper to at least partially prevent a surface of the object from contacting the magnetic material of the case. In some embodiments, the bumper is disposed between the case and an object when the object is in the case. In some embodiments, the object is a mobile electronic device.
In some embodiments, at least a portion of the case comprises a color-changing material that changes color when subjected to different environmental conditions. In some embodiments, the majority of the back of the case comprises a color-changing material. In some embodiments, the case includes designs that incorporate color-changing materials.
In some embodiments, the color-changing material is a thermochromic material that changes color due to a change in temperature of the thermochromic material. In some embodiments, the thermochromic material is a thermochromic coating, paint, and/or film. In some embodiments, the thermochromic material includes thermochromic liquid crystals and/or leuco dye. In some embodiments, the case includes an insulator between the thermochromic material and the object within the case. In some embodiments, the color-changing material is photochromic material, such as a photochromic coating, paint, and/or film.
In some embodiments, at least a portion of the back of the case is made of a magnetic material, and at least a portion of at least one of the front, bottom, top, first side, and second side is made of one or more non-magnetic materials.
Some embodiments provide a decorative skin for a mobile electronic device case. The skin includes a sheet with a first side and a second side, where the first side has magnets and/or magnetic materials for removably attaching the sheet to a case for a mobile electronic device that has a magnetic material component. The skin also includes a second side with a decoration, such that when the sheet is removably attached to the case, the decorative treatment is presented to a user. In some embodiments, the sheet has one or more through-holes. In some embodiments, the decoration comprises a thermochromic material, a photochormic material, a metameric material, a color, and/or a design.
Some embodiments provide a method of manufacturing a case for a mobile electronic device. The method includes providing one or more color-changing materials that change color when subjected to different environmental conditions, providing one or more non color-changing materials, forming one or more color-changing portions of a case, forming one or more non color-changing portions of a case, and creating a case for a mobile electronic device incorporating the one or more color-changing portions and the one or more non color-changing portions.
Some embodiments provide a method of manufacturing a case for a mobile electronic device. The method includes providing one or more color-changing materials that change color when subjected to different environmental conditions, providing one or more non color-changing materials, and forming a case for a mobile electronic device including the color-changing and the non color-changing materials.

In some embodiments, a clear coating is applied over at least a portion of the ultra-violet radiation inhibiting coating.
In some embodiments, the cases are manufactured with metameric materials.
Like reference numerals refer to corresponding parts throughout the drawings.
In some embodiments, the case includes a bumper to at least partially prevent a surface of the object (contained within the case) from contacting the magnetic material of the case. When substantially all of a case is made of metal, it may be advantageous to include a bumper or padding on the portions of the case that contact or interface with the object within the case. The bumper can reduce the likelihood that the metal case will scratch, scrape, and/or score the surface of an object within the case. In some embodiments, the bumper can act as an impact buffer, reducing the likelihood of damage to an object should the case be dropped when it is holding the object. In some embodiments, the bumper is a piece of foam, rubber, plastic, fabric, and/or leather on a surface of the case, and configured to be disposed between the case and the object when the object is in the case.
The case 3302 with the magnetic material back 3306 allows a user to position a strap on any desired portion of the magnetic material back that the user desires, like magnets on a refrigerator door. In other words, as long as the strap includes at least one magnet, the strap can be placed in any position on the magnetic material back 3306. For example,
Another advantage of a case 3302 with a magnetic material back 3306 is that various types of the straps can be equally well accommodated. For example,
Furthermore, not only can the strap 3304 be positioned by a user such that it neatly holds a wrapped cord when the cord is attached to an object as shown in
In some embodiments, the magnetic material back 3306 is exposed as shown in
In some embodiments, rather than having an encapsulating material 3314 over the magnetic material back 3306, the magnetic material back 3306 is covered with a coating material such as an opaque or translucent paint, polyurethane, scratch resistant gloss, etc. In some embodiments, the coating is applied directly to the surface of the back prior to the back being joined to the case 3302. In some embodiments, while the coating may protect the back, it does not necessarily hold it in place in the same manner as the encapsulating material. As such, in some embodiments, a portion of the case 3302 is molded over the magnetic material back 3306 such that the magnetic material back 3306 is held in place. For example, in some embodiments, the rim of case 3302 that contacts the magnetic material back 3306 is made of an elastomer material such as rubber or silicone that is molded over the edges of the magnetic material back 3306.
In other embodiments, rather than being over molded, melted, welded, or otherwise permanently attached to the case 3302, the back is slidably connected to the case 3302. For example, in some embodiments, the magnetic material back 3306 fits into a pocket 3316 or tracks in the case 3302 as shown in Figure II. This figure illustrates the magnetic material back 3306 in a position to be inserted into the pocket 3316 to clearly illustrate the pocket element of this embodiment, although when in use the magnetic material back 3306 would be slid entirely or substantially entirely into the pocket 3316. In some embodiments, the back might also slide into place from a side opening pocket rather than the top opening pocket shown in
In some embodiments, as shown in
In some embodiments, the portions of the case excluding the magnetic material back 3306, is made of one or more non-magnetic materials. For example, portions of the case can include a pliable material, which will help facilitate the insertion of an object into the case, especially in embodiments where the magnetic material back 3306 of the case 3302 is rigid. In some embodiments, the remainder of the case is made of a combination of pliable materials and rigid materials. For example, as shown in
In some embodiments, the case at least partially covers the back side of an object when the object is located within the case. In any of the embodiments described herein, the case can be made of any suitable material such as leather, plastic, rubber, fabric, polymer, metal, etc. In polymer embodiments, the polymer is selected from the group consisting of silicone and an elastomer (e.g., thermoplastic elastomer). In some embodiments, the polymer is resistant to dust. These polymers may be used in manufacturing processes such as injection molding, casting, compression molding, and die cutting. In fabric embodiments, the fabric may be a Neoprene fabric, leather, silk, cotton, denim, foil, Mylar, and the like. The fabric case will likewise be manufactured by any suitable sewing or joining technique, depending on the fabric chosen.
In some embodiments, a combination of the above mentioned materials will be used to cover various portions of the case. For example, as discussed in more detail with respect to
The elastic polymers embodiments of the case may be manufactured by processes such as injection molding, casting, compression molding, and die cutting. The type of manufacturing process selected may depend on factors such as a desired manufacturing volume, manufacturing time, and manufacturing costs of the case. Additionally, the type of manufacturing process selected may depend on a desired aesthetic design of the case. For example, in some embodiments, a two-shot injection molding process is used.
The magnets of the case may include any element or composition that is capable of producing a magnetic field. For example, the magnets may include one or more of magnetic metallic elements (e.g., iron, cobalt, nickel, etc.), composite magnets (e.g., ceramic or ferrite magnets, alnico magnets, ticonal magnets, injection molded magnets, flexible magnets), rare earth magnets (e.g., samarium-cobalt magnets, neodymium-iron-boron magnets, etc.), electromagnets, sets of any of these magnets, or any material or composition that produces a magnetic field. Examples of metals that are (or are capable of being) magnetic include, but are not limited to: ferritic stainless steels; martensitic stainless steels; SAE 400 series stainless steels (e.g., SAE Type 416 stainless steel); SAE 1000-9000 series steels (e.g., SAE 1008 steel); alloys of nickel, iron, and/or cobalt; and/or iron.
In some embodiments, the magnets are Neodymium magnets. In some embodiments, the Neodymium magnets are a grade N42. In some embodiments, the magnets are solid magnets. In some embodiments, the magnets are selected from the group consisting of donut (ring) magnets, horseshoe-shaped (U-shaped) magnets, cylindrical magnets, disc-shaped magnets, rectangular magnets, and the like. In some embodiments, the magnets are sets of magnets. The selection of the size, shape, and number of the magnets may depend on factors including, but not limited to, a desired magnetic strength, a desired form factor, a desired aesthetic, and the manufacturing process used to produce the strap.
Although not required, one or more of the case “magnets” can be made of a magnetic material rather than a magnet. The magnetic material can be made of any material that produces a magnetic field in response to an applied magnetic field. In some embodiments, the magnetic material is selected from the group consisting of a ferromagnetic material and a paramagnetic material. In some embodiments, the magnetic material is low-carbon steel. In some embodiments, the magnetic material is Vanadium carbonyl. The magnetic material may be any shape, including, but not limited to, a disc, a square, a rectangle, a decorative shape, and the like. The size and shape of the magnetic material may be selected based on factors including, but not limited to, an aesthetic design of the case and strap. Furthermore, as described in more detail, with respect to
In some embodiments the case includes holes for object elements such as speakers, a dock/charger connector, a camera/lens, an LED/flash, a ringer mode switch, an on/off switch, etc. In some embodiments, one hole will accommodate more than one element. For example, a large bottom hole is configured to expose the dock/charger connector and the speakers. Similarly, a single back hole is configured to expose the LED/flash and the camera/lens. Alternative embodiments will provide differently shaped holes such as a larger and/or differently shaped hole for the LED/flash and camera/lens and a larger and/or differently shaped hole for the dock/charger connector and the speakers. Similarly, in other embodiments, separate holes are provided for each of the LED/flash and the camera/lens. Likewise, in some embodiments, separate holes are provided for each of the speakers and the dock charger. In some embodiments holes will also be provided for access to volume buttons. The exact dimensions and placement of the holes is determined based on the specific requirements of the object inserted into the case. For example, in cases designed to house an object with a track wheel (e.g., a track wheel for a thumb placed on the side of the object), a track wheel hole is also included in the case. Similarly, for objects that include a touch screen or touch sensitive area for controlling the object's functions, holes will be provided to access these elements as well. In some embodiments, a large hole is provided in the front of the case for viewing the screen (whether touch sensitive or otherwise). In some embodiments, the front of the ease may include a transparent screen cover. In some embodiments, the camera hole may include a small built in lens to improve the quality of pictures taken with the object's built-in camera lens. In some embodiments, the edges of the holes are beveled, re-enforced with a stronger material, or covered with a protective coating. These additions allow the holes to withstand greater wear and tear during use than the case could otherwise withstand. In some embodiments, the case may include a hole to allow a support stand element to pass through the case.
In some embodiments certain elements, such as buttons, rather than just being available through a hole as described above, are instead covered. In some embodiments, the button covers are made of a pliable material such as rubber or silicone. In other embodiments, the button covers are made of a rigid material such as plastic or metal. Any of the above mentioned materials discussed with respect to the case may be used for the button covers. The button covers keep the object within the cover more protected from dirt, debris, and moisture which could otherwise accumulate. Furthermore, the button covers protect the buttons from scratches. Similarly, in some embodiments, the holes for the camera, LED/flash, and screen are covered with a transparent material such as glass or transparent plastic to similarly protect the device. In some embodiments, the button covers are recessed with respect to the exterior surface of the case, such that the button covers do not stick out past the profile of the case, and are thus less likely to be inadvertently pressed. In other embodiments, the button covers are not recessed with respect to the exterior surface of the case. It should be noted that in some embodiments, the button covers are colored differently from the case in order to make them easier for a user to locate, and to add to the aesthetic appeal of the case.
In some embodiments, at least a portion of a cord management system includes a color-changing material that changes color when it is subjected to different environmental conditions. Color-changing materials can be employed in order to give an item, such as a case or strap for a cord management system, an attractive, decorative appearance. As described in greater detail below, color-changing materials can be designed or selected in order to display dynamic color schemes on the case. For instance, when a user holds a mobile electronic device case that incorporates a thermochromic material, the heat from a user's hand may cause a handprint to appear on the case in a distinct color (or colors) from other portions of the case. Also, in some embodiments, the case is configured so that a user can use a finger, flashlight, laser, heat pen, heat brush, or other object to “draw” on the case. The various uses and applications for a case with a color-changing material can add an element of novelty and attractiveness to the cord management system, and can increase the appeal and entertainment value of such cases. Also, thermochromic materials are used in some embodiments to provide information to a user of a device, for example by indicating a temperature of a device. Color-changing materials, including thermochromic materials, are disclosed in greater detail herein.
In some embodiments, a cord management system includes a case for a mobile electronic device. Mobile electronic devices include any of a class of electronic devices that are small and light enough to be easily transported with a person. A mobile electronic device is a self-contained electronic device which usually has one or more of: a screen, buttons, a touch screen, a keyboard, a speaker, a lens, and a microphone. They are often battery powered, and often include electronic components (e.g., batteries, processors, memory, circuit boards, and the like) surrounded by a cover or housing. In some embodiments, a mobile electronic device is an audio player, a portable video player, a handheld gaming system, a navigation device, a tablet computer, a laptop computer, an e-book reader, a personal digital assistant, a camera, a camcorder, and/or a handheld video projector. Mobile electronic device cases are often used to protect, cover, and/or accessorize mobile electronic devices.
In some embodiments, the color-changing material is a thermochromic material. Thermochromic materials are materials that change color due to changes in the temperature of the material and/or the environment surrounding the material. In some embodiments, the color-changing material is a photochromic material. Photochromic materials change color due to a change in the wavelength and/or intensity of light incident on the material. Photochromic materials are discussed in greater detail herein. As used herein, a change in color corresponds to any change in hue, brightness, shade, tint, and/or saturation that is detectable by the human eye. In some embodiments, a change in color of a material corresponds to a change from one Pantone color standard to another Pantone color standard. In some embodiments, a color changing material will change to (or will transition between) a first color (e.g., black) and a second color (e.g., green). In some embodiments, a color changing material will transition between additional colors, for example, changing between black and green and purple and blue.
In some embodiments, other coatings or materials that provide interesting or decorative visual characteristics are used. For example, in some embodiments, materials that exhibit geometric metameric failure are used. Such materials appear to a viewer to be different colors depending on the viewing angle, the viewing distance, and/or the lighting angle. As used herein, materials exhibiting geometric metameric failure (including paints, coatings, dyes, etc.) are referred to as metameric materials.
Attention is now drawn to
In some embodiments, a color-changing material is incorporated in a case in such a way that a design becomes visible or not visible (or less visible) only when certain environmental conditions exist.
In some embodiments, the design 4004 is made of (or includes) a color-changing material that is the same color as the background 4005 when the color-changing material is subject to a first environmental condition, and is a different color from the rest of the case when the background 4005 is subject to another environmental condition. Thus, the design 4004 will appear to be the same color as the background 4005 (i.e., not visible or less visible) or appear to he a different color than the background 4005 (i.e., visible) based on the specific environmental condition of the color-changing material. On the other hand, in some embodiments, the background 4005 is made of (or includes) a color-changing material that is the same color as the design 4004 when the color-changing material is subject to a first environmental condition, and is a different color from the design 4004 when the case is subject to another environmental condition. In some embodiments, both the design 4004 and the background 4005 are made of (or include) a color-changing material. In these embodiments, the color changing materials each display different colors at different environmental conditions, and/or different colors at the same environmental conditions.
In the foregoing description, the flower design is merely exemplary, and the design could be any design. In some embodiments, the design is any of: representational designs (e.g., flowers, animals, faces), non-representational designs (e.g., dots, lines, patterns), and informational designs (e.g., words, logos, trademarks).
In some embodiments, the color-changing material is a thermochromic material that is configured to change color in response to a temperature change caused by the device within the case. For example, mobile electronic devices often heat up when they are in use, such as when a user is making a telephone call on a mobile telephone. In some cases, the increased temperature of the device (and the case holding the device) is caused by the heating up of a battery during use. Thus, for example, a case can be designed for a mobile electronic device where the thermochromic material is designed to change color in accordance with the increased battery temperature typical for that device.
In some embodiments, a case includes a design that displays certain colors, symbols, and/or designs to indicate the temperature of the device. Such a design may provide a user with other information about the device as well. For example, since the temperature of a battery powered electronic device may increase over a period of time, the temperature of the device (and accordingly of a case holding the device) may be used as a proxy for the duration that a device has been in use. Thus, a thermochromic material is sometimes used to indicate how long a user has been using an electronic device.
Throughout the present discussion, the different designs and colors that are incorporated into a case may be selected based on design preferences, material constraints, and/or desired operating temperatures. Furthermore, specific temperature ranges in which designs and colors are displayed may be subject to particular design choices. These design choices are all considered to be within the scope of the invention. For instance, in some embodiments, a design may be visible at a higher temperature and not visible (or less visible) at a lower temperature. Alternatively, a design may be visible at a lower temperature and not visible (or less visible) at a higher temperature. In some embodiments, a case can be configured to display multiple different designs based on different temperatures of combinations of temperatures.
In some embodiments, it is preferable that the heat produced by the electronic device does not cause a thermochromic material to change color. For instance, in some embodiments the heat of a user's hand is the main cause of a color change on a case. Also, in some embodiments, a case may incorporate a temperature indicating design for indicating the temperature of the air surrounding the case. Accordingly, it may be beneficial for the portion of the case comprising thermochromic material to be least partially thermally insulated from the electronic device within the case in order to limit the effect of a battery's heat on the thermochromic material. Insulating materials are discussed in greater detail herein with reference to
In some embodiments, the protective coating 4302 is an at least semi-transparent coating, painting, covering, sealer, film, sheet, and/or finish. The protective coating 4302 is sometimes designed to help prevent scratches, dents, or other damage to an underlying layer (e.g., the color changing material 4306, an alternative paint layer, and/or a magnetic material portion 4308). In some embodiments, the protective coating 4302 helps prevent underlying layers from peeling and/or flaking. In some embodiments, the protective coating 4302 includes the ultra-violet inhibiting coating 4304, or otherwise includes an ultra-violet radiation inhibiting material. In these embodiments, the two coatings may only be a single layer of material. In some embodiments, the protective coating 4302 is urethane, polyester, lacquer, epoxy, resin, plastic, and/or glass.
The color-changing material 4306 is a material that changes color when subjected to different environmental conditions, as described in more detail below. The color-changing material 4306 is, in some embodiments, a thermochromic material, a photochromic material, or a metameric material. In some embodiments, the color-changing material 4306 is a paint, coating, and/or film layer component of a case. Also, the color-changing material 4306 is substituted with a standard, non-color-changing material in some embodiments.
In some embodiments, the ultra-violet radiation inhibiting coating 4304 prevents or limits the transmission of ultra-violet radiation to subsequent layers or coatings of the case. In some embodiments, the color-changing material 4306 degrades when exposed to ultra-violet radiation, resulting in diminished color changing properties. In some embodiments, other colors, paints, and/or designs fade when exposed to ultra-violet radiation. Thus, ultra-violet radiation inhibiting coating 4304 helps limit the damaging effects of ultra-violet radiation.
In some embodiments, a case includes a magnetic material portion 4308 and a polymer portion 4310. The specific materials for a case in accordance with embodiments of the present invention are discussed in greater detail elsewhere in this application, and will not be discussed in detail here.
In some embodiments, the insulating element 4312 is an insulator such as glass, fiberglass, plastic, elastomer, and/or rubber. In some embodiments, a case is configured such that an air gap exists between the thermochromic material and a device within the case. The air gap insulates the device from the thermochromic material, and can be used in addition to or instead of the insulating element 4312. Thus, in some embodiments, the case does not include an insulating element 44312.
In some embodiments, the insulating element 4312 is a portion of a case that has a color-changing material. For example, a plastic or polymer case may have a color-changing paint on an outer surface, and the plastic or polymer that makes up the case may act as an insulating element.
It is understood that not all of the materials or components illustrated in this cross section are necessarily used in all embodiments of the present invention. For example, some embodiments of a case do not include magnetic materials. Furthermore, additional components not identified or discussed here may likewise be incorporated without departing from the spirit of the invention.
In some embodiments, a color-changing material is incorporated in a skin that is applied to a portion of the case.
In some embodiments, the decorative skin 4404 further comprises one or more edges defining through-holes 4405 between the first and second sides, wherein the one or more through-holes 4405 are configured to allow optical access through the skin 4404 by a component of the mobile electronic device. For example, the through-holes are sometimes positioned so that a lens and/or a flash component of a mobile electronic device are not covered by the skin.
In some embodiments, at least a portion of the non-contacting side of the skin includes a thermochromic material. In some embodiments, the skin does not include a thermochromic material, but has another design and/or decoration instead. Designs may include, but are not limited to, representational designs, non-representational designs, and informational designs. Such designs may include a color, word, picture, photograph, outline, shape, image, and/or logo. In some embodiments, decorative skins include a magnet or magnetic material 4406 as an attachment mechanism allowing them to attach to and decorate and/or personalize a case for an object. In some embodiments, the case has a magnetic material surface such as a magnetic material back, and skins are magnetically attached to the case via the magnetic material surface. In some embodiments, the attachment mechanism is selected from any of: adhesive, Velcro, van der Waals force attachment mechanisms (e.g., Gecko tape), and suction devices (e.g., suction cups). In some embodiments, the skins are permanently attached to the case (e.g., with an adhesive).
In some embodiments, a color-changing material is incorporated into a decorative sheeting material. In some embodiments, the decorative sheeting material is permanently or semi-permanently incorporated into a case for a mobile electronic device.
In some embodiments, the decorative sheeting 4409 (or the substrates 4410, 4416 of the decorative sheeting 4409) are so dimensioned so as to cover substantially all of a surface of a case for a mobile electronic device, such as a mobile phone, music/audio player, laptop computer, tablet computer, and the like. In some embodiments, the dimensions correspond to a back surface of a case for a mobile electronic device.
In some embodiments, the decorative sheeting 4409 further comprises one or more edges defining through-holes between the first and second sides, wherein the one or more through-holes are configured to allow optical access through the sheet by a component of the mobile electronic device. For example, the through-holes are sometimes positioned so that a lens and/or a flash component of a mobile electronic device are not covered by the sheet.
In some embodiments, the decorative sheeting 4409 is combined with a magnetic material 4406 to form a decorative skin for a mobile electronic device case, as described above.
In some embodiments, the range of temperatures between which the thermochromic material changes colors is 32-95 degrees Fahrenheit. In some embodiments, the temperature range is 50-95 degrees Fahrenheit. In some embodiments, the temperature range is 70-140 degrees Fahrenheit. The thermochromic material can be designed to display various colors, ranges of colors, or combinations of colors, in response to different material temperatures. In some embodiments, the material displays only two colors. In some embodiments, the material displays three or more colors. In some embodiments, the material may simultaneously display a first portion having a first color and a second portion having a second color. For example the material may display a blue portion and a green portion. In some embodiments, the material displays multiple portions and multiple colors (e.g., portions displaying blue, green, purple, red, orange, etc.).
Throughout the discussion of thermochromic materials, it should be recognized that a thermochromic material may exhibit a particular color throughout a range of temperatures. In other words, when a material is described as having a color when the material is “at” or when the material “has” a certain temperature, it is understood that the color may appear within a range of temperatures. In some embodiments, a thermochromic material has a first color (e.g., black) when the material is between a first and a second temperature (e.g., between 60-70 degrees Fahrenheit), and a second color (e.g., blue) when the material is between a third and a fourth temperature (e.g., 120-140 degrees Fahrenheit). In some embodiments, the thermochromic material changes fluidly between the first and second color as the temperature rises from the second to the third temperature. A material (or combination of materials) may also exhibit more than one color in response to a single temperature or temperature range. Furthermore, a thermochromic material may exhibit the same or a similar color at two non-contiguous temperature ranges. For example, a thermochromic material may be black when the material is between 60 and 70 degrees Fahrenheit, and black when the material is above 95 degrees Fahrenheit, while displaying various other colors in the intermediate temperature region.
Several types of thermochromic materials exist that are employed in various embodiments of the invention, including thermochromic liquid crystals, and/or Leuco dyes. One of skill in the art will recognize that these substances can be applied to a case in many different ways, and through the use of many different coatings. For example, a thermochromic material can be incorporated into paint, dye, epoxy, ink, wax, film, and/or any other type of coating or covering that will allow the thermochromic material to be seen by a user of the case. In some embodiments, the thermochromic material is embedded in paint or other coating that is applied to a portion of or all of the case. In some embodiments, multiple thermochromic materials are combined in a single paint or coating. For example, a first thermochromic material exhibiting a color change over a first temperature range and a second thermochromic material exhibiting a color change over a second temperature range may be combined to produce a paint or coating exhibiting interesting or desirable color-changing results. In some embodiments, more than two thermochromic materials are used in a single paint or coating.
In some embodiments, the paint or coating is applied substantially only to outer portions of the case, such as those portions of the case that are visible when a mobile electronic device is in the case. In some embodiments, the thermochromic material is embedded in a polymer, plastic, elastomer, or other material that makes up a portion of or all of the case. For example, a surface of a case is sometimes made out of a plastic that has been treated with (or otherwise includes) a thermochromic material. In some embodiments, the entire case is molded from a plastic that has been treated with (or otherwise includes) a thermochromic material.
In some embodiments, the color-changing material used in a case for a mobile electronic device is a photochromic material. Photochromic materials are materials that change color due to a change in the incident light. For instance, a photochromic material may change color when it is exposed to a change in intensity and/or wavelength of light. (As referred to herein, “light” can include electromagnetic radiation of many wavelengths, even those that are outside of the visible spectrum.) In some embodiments, photochromic materials include photochromic substances or molecules such as spiropyrans and spirooxazines, diarylethcnes, azobenzenes, and/or photochromic quinones. Photochromic materials can be used instead of, or in addition to, the thermochromic materials described above. In particular, the disclosure relating to thermochromic materials is understood to apply by analogy to photochromic materials as well. Where the temperature of the thermochromic material is described as the cause of a color change, the wavelength or intensity of incident light on a photochromic material is understood to be the cause of a color change.
In the foregoing description of thermochromic and photochromic materials, both the color-changing substances (e.g., the liquid crystals, Leuco dyes, and/or other color-changing molecules) and the materials that use such substances to display color-changing effects (e.g., film embedded with thermochromic dye, paint with thermochromic liquid crystals, etc) may be referred to as “photochromic materials” and/or “thermochromic materials.” Furthermore, any discussion relating to one type of color-changing material (e.g., thermochromic materials) is understood to apply to similar embodiments using other color-changing materials as well (e.g., photochromic materials).
Also, any of the above described methods are understood to equally apply to methods of manufacturing cases with metameric materials. For example, some embodiments provide methods according to the above descriptions where metameric materials are substituted for color-changing materials and/or thermochromic materials.
The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to best explain the principles of the invention and its practical applications, to thereby enable others skilled in the art to best utilize the invention and various embodiments with various modifications as are suited to the particular use contemplated.
In some embodiments, the computer system forms (3506) a cord-attachment mechanism located at a third location on the case. In some embodiments, the computer system forms (3508) one or more button covers configured to protect one or more buttons of the object, while allowing the one or more buttons to be operable. In some embodiments, the computer system forms (3510) one or more holes configured to expose one or more elements of the object.
In some embodiments, the computer system forms (3704) a cord-attachment mechanism; one or more button covers; and one or more holes.
In some embodiments, the color-changing material used in the above case is thermochromic (4516), while in other embodiments, the color-changing material is photochromic (4518). In some embodiments. the color-changing material uses both thermochromic and photochromic materials.
In some embodiments, the case is manufactured according to an assembly process (4610). One or more color-changing portions for a case are formed using the one or more color-changing materials (4612). One or more non color-changing portions for a case are formed using the one or more color-changing materials (4614). A case for a mobile electronic device is created, where the case incorporates the one or more color-changing and the one or more non color-changing portions (4616). In some embodiments, the case is created by assembling the color-changing and non color-changing portions.
In some embodiments, the case is manufactured according to a molding process (4618). A case for a mobile electronic device is faulted including the color-changing and non color-changing materials (4620). In some embodiments, the case is formed by injection molding. In some embodiments, the color-changing material is a thermochromic material (such as thermochromic liquid crystals) that is incorporated into a non color-changing polymer that is then injection molded or thermoformed to form a ease for a mobile electronic device.
A thermochromic coating is applied to at least a portion of the case (4708). In some embodiments, the thermochromic coating is any of: paint, ink, dye, film, and powder coatings. In some embodiments, the thermochromic coating is sprayed on the portion of the case. In some embodiments, the thermochromic coating is printed on the portion of the case. In some embodiments, the thermochromic coating is a decorative sheeting, e.g., the decorative sheeting 4409.
In some embodiments, an ultra-violet radiation inhibiting coating is applied over at least a portion of the thermochromic coating (4710). This layer helps protect the thermochromic material from degradation due to ultra-violet radiation. In some embodiments, a substantially clear coating is applied over at least a portion of the ultra-violet radiation inhibiting coating (4712). The substantially clear coating is sometimes a hard, protective coating to help prevent the thermochromic and/or the ultra-violet inhibiting coatings from being chipped, peeled, scratched, or otherwise damaged. In some embodiments, an ultra-violet inhibiting material is incorporated into a substantially clear coating, in order to reduce the number of steps in the method (4700). In some embodiments, the ultra-violet inhibiting material is sprayed, printed, screen-pressed, and/or painted on the case.
A second substrate is provided (4804). In some embodiments, an ultra-violet inhibiting material is applied to the second substrate (4805). In some embodiments, the ultra-violet inhibiting material is a coating that is sprayed or painted on. In some embodiments, the ultra-violet inhibiting material is a film.
A color-changing material is applied to the second substrate (or to the ultra-violet inhibiting material) to form a second layer (4806). The color-changing material is a material that changes color when subjected to different environmental conditions, such as a thermochromic or photochromic material.
The first layer and the second layer are layered to form a decorative sheeting (4808). When the two layers are combined in the layering step (4808), the two layers are oriented with respect to one another such that the color-changing material is between the first substrate and the second substrate.
The ultra-violet inhibiting material applied in step (4805) helps protect the color-changing material from degradation due to ultra-violet radiation. As such, in some embodiments, it is applied to the substrates such that, when the decorative sheeting is applied to an object, the color-changing material is between the object and the ultra-violet inhibiting material.
In the above description, where a material is described as applied to a substrate, one of skill in the art will understood that the material can be applied directly to the substrate, or applied to another sub-layer or material already applied to the substrate.
The methods 3500-3700 and 4500-4800 may be governed by instructions that are stored in one or more computer readable storage mediums and that are executed by one or more processors of one or more computer systems. Each of the operations shown in
Note that although a magnet may be considered a magnetic material, a magnetic material is not necessarily a magnet. Specifically, a magnetic material is a material or composition that produces a magnetic field in response to an applied magnetic field (e.g., a magnetic field produced by a magnet). The magnetic material may include one or more of a ferromagnetic material and a paramagnetic material. Note also that the term “earphones” is used in this specification to refer to any device (e.g., headphones, ear buds. etc.) that an end user places on or in the ears to produce sounds.
Note that the term “connector” is used in this specification to refer to any type of connector or plug. For example, the connector may be an electrical connector (e.g., an audio connector, a video connector, a power connector, a computer connector, etc.) or non-electrical connector.
The magnets described herein may include any element or composition that is capable of producing a magnetic field. For example. the magnets may include one or more of magnetic metallic elements (e.g., iron, cobalt, nickel, etc.), composite magnets (e.g., ceramic or ferrite magnets, alnico magnets, ticonal magnets, injection molded magnets, flexible magnets), rare earth magnets (e.g., samarium-cobalt magnets, neodymium-iron-boron magnets, etc.), electromagnets, sets of any of these magnets, or any material or composition that produces a magnetic field. In some embodiments, the magnets are Neodymium magnets. In some embodiments, the Neodymium magnets are a grade N42.
Note that the combination of the grade (i.e., the composition of materials, wherein a higher number for the grade indicates a higher magnetic strength per unit volume), the diameters, the shape, and the thickness of a magnet determines the magnetic strength of the magnet. The magnetic strength of a larger magnet (e.g., larger surface area, diameter, and/or thickness) having a lower grade (e.g., lower “N” number) may have greater magnetic strength than a smaller magnet with a higher grade. For example, Neodymium magnets have the following grades, ordered from lowest to highest strength, N28, N30, N33, N35, N38, N40, N42, N45, N48, N50, and N52. A large N28 magnet may be stronger than a small N52 magnet.
Note that a magnetic material is a material or composition that produces a magnetic field in response to an applied magnetic field. The magnetic material may include one or more of a ferromagnetic material and a paramagnetic material. In some embodiments, the magnetic material is low-carbon steel. Aly combination of magnets and magnetic material that allows for the magnetic attachments described herein to function may be used.
Note that a magnet or magnetic material may be attached to an electronic device using adhesives, suction devices (e.g., suction cups), Velcro, van der Waals force attachment mechanisms (e.g., “Gecko” tape), snaps, buttons, and the like. Also note that the magnetic material may be molded into the electronic device, a back panel of the electronic device, and/or a case for the electronic device.
Note that the term “magnetically attached,” when applied to two magnets, refers to two magnets being attached to each other by an attractive magnetic force between the two magnets. In contrast, the term “magnetically detached,” when applied to two magnets, refers to two magnets that are no longer attached to each other. Although the two magnets may no longer be magnetically attached to each other, the two magnets may still be “magnetically coupled” to each other. In other words, each magnet may feel a magnetic force generated by the magnetic field of the other magnet. This magnetic force is a function of the distance between the two magnets.
Also note that this specification refers to two magnets (or magnets and magnetic materials) being “magnetically attached” to each other even if the magnets are separated by intermediary materials. When a magnet is magnetically attached to another magnet and a decoupling force that is greater than or equal to the predefined threshold is exerted against the predefined attractive magnetic force between the magnets, the magnets become magnetically detached from each other.
Note that the term “case” refers to any type of material that covers or partially covers the object. For example, the case may include, but is not limited to flip case, a zipper case, a skin, an open-faced case, and the like.
