## Background
RELATED APPLICATIONS
This application is a continuation of PCT Patent Application No. PCT/US2010/031087, which was filed on Apr. 14, 2010, which application is incorporated by reference herein in its entirety.


TECHNICAL FIELD
The disclosed embodiments relate generally to a system and a method for managing cords.
BACKGROUND
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.

DESCRIPTION OF EMBODIMENTS
Cord Management System
To address the aforementioned problems, some embodiments provide a cord management system that secures the cord and prevents the cord from becoming tangled. FIG. 1 illustrates components of an exemplary cord management system 100. The components of the cord management system 100 may include a magnetic strap 101, one or more magnetic beads 102, and a magnetic material 103. The magnetic strap 101 is described in more detail with respect to FIG. 6-12 below, the magnetic beads 102 are described in more detail with respect to FIG. 13-14 below. The magnetic material 103 is described in more detail with respect to FIG. 15G below.
In some embodiments, the cord management system 100 is provided to an end user as a kit that includes components that the end user assembles to form the cord management system. The process of assembling the cord management system 100 is described in more detail with respect to FIG. 15 below. In some embodiments, the kit includes a subset of the components illustrated in FIG. 1. For example, the cord management system 100 may include: (1) the magnetic strap 101, (2) the magnetic strap 101 and the magnetic beads 102, (3) the magnetic strap 101 and the magnetic material 103, (4) the magnetic strap 101, the magnetic beads 102, and the magnetic material 103, or (5) the magnetic beads 102.
In some embodiments, only a subset of the cord management system 100 is used to secure a cord and prevent the cord from becoming tangled. For example, the end user may choose one of several options to secure the cord using: (1) the magnetic strap 101, (2) the magnetic strap 101 and the magnetic beads 102, (3) the magnetic strap 101 and the magnetic material 103, (4) the magnetic strap 101, the magnetic beads 102, and the magnetic material 103, or (5) the magnetic beads 102. These options are described below.
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.
Option 1: Magnetic Strap
In some embodiments, the end user uses the magnetic strap 101 to secure a cord. As illustrated in FIGS. 2A-2E, a cord 201 is wrapped around the magnetic strap 101 substantially perpendicular to and/or otherwise across the magnetic strap 101 at any angle. In some embodiments, the cord 201 is a cord for earphones. Note 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. For example, the cord 201 may include speakers (e.g., ear buds) 202 and 203, as illustrated in FIGS. 2A-2E. In some embodiments, the magnetic strap 101 is placed on an object and the cord 201 is wrapped around both the object and the magnetic strap 101 in a direction substantially perpendicular to and/or across the length of the magnetic strap 101. For example, the object may be an electronic device 210, as illustrated in FIGS. 2A-2C. Similarly, the object may be a hand as illustrated in FIG. 2D-2E.
In some embodiments, after a desired length of the cord 201 is wrapped around the magnetic strap 101, the magnetic strap 101 is folded over to form a loop around the cord 201 to secure the cord 201 to the magnetic strap 101. These embodiments are illustrated in FIG. 2B (e.g., an electronic device) and FIG. 2D (e.g., a hand). Once the magnetic strap 101 is secured around the cord 201, the object can be stored in a pocket, a bag, or a purse without the cord 201 becoming tangled or without the cord 201 becoming unwound from the object. In addition, once the magnetic strap 101 is secured around the cord 201, the magnetic strap 101 can be removed from the object and stored in a pocket, a bag, or a purse without the cord 201 becoming tangled or without the cord 201 becoming unwound from the magnetic strap 101.
Although FIGS. 2B and 2D illustrate a cord that is completely secured by the magnetic strap 101, the end user may choose to wrap only a portion of the cord 201 in the magnetic strap 101. For example, FIG. 2G illustrates an end user 230 that is holding the electric device 210 with the speakers 202 and 203 inserted in his ears. As illustrated in FIG. 2G, the cord 201 is wound around the electronic device 210 and the magnetic strap 101 several times and is secured with the magnetic strap 101. In this way, the end user 230 has reduced the length of the cord 201 that is free and dangling. In other words, the length of the cord 201 is such that the end user 230 can perform desired functions and move the electronic device 210 without dislodging the speakers 202 and 203 and without having too much slack on the cord 201.
In some embodiments, magnets located at magnetic attachment points 104 and 105 on the magnetic strap 101 keep the magnetic strap 101 in the loop configuration when the magnetic strap 101 is folded over to form the loop. Note that the magnetic attachment points 104 and 105 may be replaced with other types of attachment mechanisms. For example, the attachment mechanism may include Velcro, adhesives, suction devices (e.g., suction cups), van der Waals force attachment mechanisms (e.g., “Gecko” tape), snaps, buttons, friction mechanisms, buckles, springs, bistable springs (e.g., a slap bracelet), a sleeve that inserts into a slot, a peg that is inserted into a hole, and hinges.
In some cases, the end user may desire to remove the cord 201 from an electronic device onto which the cord 201 is attached and store the cord 201 separately from the electronic device. In these cases, it is highly desirable to prevent the separated cord 201 from becoming tangled. Thus, in some embodiments, after the cord 201 is secured to the magnetic strap 101, the magnetic strap 101 is removed from the object. These embodiments are illustrated in FIGS. 2C and 2F. Since the cord 201 is secured to the magnetic strap 101, removing the magnetic strap 101 from the object removes the cord 201 from the object. When the magnetic strap 101 is removed from the object, the cord 201 remains looped around the magnetic strap 101. Thus, the cord 201 that is wrapped around the magnetic strap 101 does not become tangled when placed in a pocket, a bag, or a purse.
In some cases, after wrapping the cord 201 around the electronic device so that the electronic device may be stored without the cord 201 becoming tangled, the end user may wish to use the electronic device again. Thus, in some embodiments, after the cord 201 is secured by the magnetic strap 101, the cord 201 is deployed from the magnetic strap 101. In some embodiments, the cord 201 is deployed from the magnetic strap 101 by pulling the end of the cord 201 in a direction substantially parallel to the length of the magnetic strap. For example, FIGS. 2H, 2J, and 2K illustrate the deployment of the cord 201 when the cord 201 is wrapped around the electronic device 210. As illustrated in FIG. 2H, the end user pulls on the speakers 202 and 203 in a direction substantially parallel to the length of the magnetic strap 101. As illustrated in FIG. 2J, the force that the end user exerts on the cord 201 causes the magnetic strap 101 to detach from the loop and become open. As the end user continues pulling on the cord 201, the cord 201 unwinds from the electronic device 210, as illustrated in FIG. 2K. Note that the user may stop unwinding the cord 201 from the electronic device at any time. For example, user may partially deploy the cord 201 and secure the cord 201 using the magnetic strap 101 as illustrated in FIG. 5A.
In some embodiments, the magnetic strap 101 is used to secure one or more of: drapery, drapery cords, power cords, extension cords, hoses, ropes, kite strings, fishing lines, and the like.
Option 2: Magnetic Strap and Beads
Although the magnetic strap 101 may be used by itself as a cord management system, other components may be added to the cord management system to provide a different user experience. In some embodiments, the cord management system includes the magnetic strap 101 and one or more of the magnetic beads 102. The magnetic beads 102 may be used for several purposes. In some embodiments, the magnetic beads 102 are used to assist in the wrapping of the cord 201 around the electronic device 210 and the magnetic strap 101. In some embodiments, the magnetic beads 102 are used to keep the speakers 202 and 203 coupled to each other when the cord 201 is wrapped around the electronic device 210. In some embodiments, the magnetic beads 102 are used to secure the speakers 202 and 203 to a predetermined point on the cord 201. In some embodiments, the magnetic beads 102 are used to secure excess cord after the cord 201 is wrapped around the electronic device 210. In some embodiments, the magnetic beads 102 are used to secure the cord under the chin of an end user. These embodiments are described below.
FIGS. 3A to 3E illustrates a process for managing a cord using the magnetic strap 101 and the magnetic beads 102, according to some embodiments. Note that the magnetic beads 102 may include one or more of magnetic beads 301, 302, 303, and 304, each having an embedded magnet, as described below. Also note that at least a subset of the magnetic beads 301, 302, 303, and 304 may be substituted for a magnetic material that is embedded in the magnetic beads 301, 302, 303, and 304. Furthermore, additional magnetic beads, above and beyond the magnetic beads 301, 302, 303, and 304, may be included in the cord management system 100. Among other things, these additional magnetic beads may be used as replacements for lost magnetic beads.
As illustrated in FIG. 3A, a connector 204 of the cord 201 (and/or the cord 201) is inserted into a cord attachment mechanism 109 of the magnetic strap 101. Note that the term “connector” is used in this specification to refer to any type of connector or plug. For example, the connector 204 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 connector 204 of the cord 201 is then attached to a corresponding connector 211 on the electronic device 210. The magnetic strap 101 is then placed on the electronic device 210 so that the length of the magnetic strap 101 is collinear with the direction in which the connector 204 of the cord was inserted into the corresponding connector 211 on the electronic device 210. As illustrated in FIG. 3A, the corresponding connector 211 on the electronic device 210 is located at a top edge of the electronic device 210. Thus, in this case, the length of the magnetic strap 101 is parallel to the length of the electronic device 210. If, however, the corresponding connector 211 of the electronic device 210 were located at a side edge of the electronic device 210, the length of the magnetic strap 101 may run in a direction perpendicular to the direction illustrated in FIG. 3A or at another angle other than the angle illustrated in FIG. 3A.
In some embodiments, a magnetic bead 301 is attached to the cord 201 at a predetermined location on the cord 201. In some embodiments, the predetermined location is selected so that when the cord 201 is bent towards the magnetic attachment point 104, the magnetic bead 301 becomes magnetically attached to the magnetic strap 101 at the magnetic attachment point 104. Note that the term “magnetically attached” is defined below. The magnetic bead 301 allows the end user to start wrapping the cord 201 around the electronic device and the magnetic strap 101 without needing to hold the cord 201 onto the magnetic strap 101 or the electronic device 210, as illustrated in FIG. 3B. Note that these embodiments are optional. Although FIGS. 3B-3E illustrate the magnetic bead 301 attached to the cord 201, the magnetic bead 301 may be omitted. For example, an experienced end user may be able to start wrapping the cord 201 around the magnetic strap 101 and the electronic device 210 without the aid of the magnetic bead 301 and without needing to hold the cord 201 onto the magnetic strap 101 or the electronic device 210.
The cord 201 is then wrapped around the magnetic strap 101 and the electronic device 210, as illustrated in FIGS. 3C-3E. In some embodiments, the cord 201 is wrapped around the magnetic strap 101 substantially perpendicular to a length of the magnetic strap 101. Note that if the length of the magnetic strap 101 runs in a direction perpendicular to the direction or at an angle other than the angle illustrated in FIGS. 3A-3E, the cord 201 is wrapped around the length of the electronic device 210 so that the cord 201 is substantially perpendicular to the magnetic strap 101.
FIG. 3D illustrates the cord 201 after it has been wrapped around the electronic device 210. In some embodiments, magnetic beads 302 and 303 are attached on the cords for the speakers 202 and 203 at a predetermined distance from the speakers 202 and 203. In some embodiments, one of the magnets 302 and 303 is substituted for magnetic material. In some embodiments, the magnets of the speakers 202 and 203 are used in lieu of the magnets 302 and 303. In some embodiments, the magnetic beads 302 and 303 are magnetically attached to each other so that the speakers 202 and 203 are coupled to each other. By magnetically attaching the magnetic beads 302 and 303 to each other, the cord for each of the speakers 202 and 203 has a reduced likelihood of becoming tangled with each other or with other parts of the cord 201. The predetermined distance may be selected so that the magnetic beads 302 and 303 are located on the cords just below the speakers 202 and 203, as illustrated in FIG. 3D. As illustrated in FIG. 3E, after the magnetic strap 101 is folded over to form the loop, the free end of the cord 201 (i.e., the end attached to the speakers 202 and 203) may be allowed to dangle freely. As illustrated in FIG. 3F, after the magnetic strap 101 is folded over to form the loop, the free end of the cord 201 may be folded over so that the magnetic beads 302 and 303 are magnetically attached to the magnetic attachment point 105. As illustrated in FIG. 3F, the speakers 202 and 203 no longer dangle.
In some instances, after the magnetic strap 101 is folded over into the loop configuration, there may be a portion of the cord 201 that is not secured by the magnetic strap 101 (i.e., a portion of the cord from the magnetic strap 101 to the speakers 202 and 203). If the portion of the cord 201 that is not secured by the magnetic strap 101 is long, the cord 201 may become caught on other objects (such as when placed in a pocket, a bag, or a purse). For example, the final wrap of the cord 201 may place the speakers 202 and 203 on front side of the electronic device 210 (i.e., the opposite side of the electronic device 210 illustrated in FIG. 3E). To address these cases, in some embodiments, a magnetic bead 304 is attached on the cord 201 so that when the cord 201 is wrapped around the electronic device 210, the magnetic bead 304 is located on the front side of the electronic device 210. These embodiments are illustrated in FIG. 3G. The magnetic beads 302 and 303 are then magnetically attached to the magnetic bead 304. Note that the end user may slide and/or otherwise readjust the magnetic beads 302 and 303 up and down the cord 201 so that the magnetic beads 302, 303, and 304 can be magnetically attached to each other. Although the speakers 202 and 203 may still dangle, the amount of the cord 201 that is dangling can be reduced.
In some cases, the end user may not wish to fold over the cord 201 to secure the free end of the cord 201 (e.g., as illustrated in FIG. 3F). In these cases, the magnetic bead 304 may be attached on the cord 201 so that when the cord 201 is wrapped around the electronic device 210, the magnetic bead 304 is located on the back side of the electronic device 210, as illustrated in FIG. 3H. The magnetic beads 302 and 303 are then magnetically attached to the magnetic bead 304. Note that the end user may slide the magnetic beads 302 and 303 up and down the cord 201 so that the magnetic beads 302, 303, and 304 can be magnetically attached to each other. Although the speakers 202 and 203 may still dangle, the amount of the cord 201 that is dangling can be reduced.
In some cases, the end user may not wish to use the magnetic strap 101 to secure the cord. In these cases, the end user may magnetically attach the magnetic beads 302 and 303 to magnetic material that is attached to the electronic device 210. The use of magnetic material in conjunction with the electronic device 210 is described in more detail below.
In some embodiments, the end user slides the magnetic beads 302 and 304 so that free end of the cord 201 does not slide back through the loop (e.g., as illustrated in FIG. 3J). In some embodiments, the end user wraps a portion of the free end of the cord 201 over itself (e.g., in a shape of a bow tie, as illustrated in FIG. 3K) so that the amount of the cord 201 that is left dangling is reduced. The end user then secures the wrapped portion of the free end of the cord 201 using the magnetic strap 101 as illustrated in FIG. 3K.
When deploying the cord 201, the magnetic strap 101 flips back to the open position (i.e., the magnetic strap 101 lays substantially flat on the electronic device 210), as illustrated in FIGS. 2J and 2K.
Note that the dimensions of the magnetic strap 101 may be selected to accommodate cords of varying lengths and thicknesses. The dimensions of the magnetic strap 101 are also selected to accommodate objects (e.g., portable electronic devices, etc.) of varying sizes. FIGS. 20A to 20E illustrate a process for managing a cord, according to some embodiments. The process illustrated in FIGS. 20A to 20E is similar to the process illustrated in FIGS. 3A to 3E, except that the magnetic strap 101 is attached to an electronic device 2001 having a different shape and size as compared to the electronic device 210.
As illustrated in FIG. 20A, the connector 2006 is attached to the electronic device 2001. The cord 2005 (e.g., the cord 201) is then wrapped around the magnetic strap 101 and the electronic device 2001, as illustrated in FIGS. 20B-20D. In some embodiments, the cord 2005 is wrapped around the magnetic strap 101 substantially perpendicular to and/or otherwise across the magnetic strap 101 at any angle.
In some embodiments, the magnetic bead 2013 (e.g., the magnetic bead 301) is first magnetically attached to the magnet of the magnetic strap 101 before the cord 2005 is wrapped around the magnetic strap 101 and the electronic device 2001. These embodiments are illustrated in FIG. 20B. By magnetically coupling the magnetic bead 2013 to the magnetic strap 101, a user does not need to hold the cord 2005 to the electronic device 2001 or to the magnetic strap 101 while wrapping the cord 2005 around the electronic device 2001.
FIG. 20D illustrates the cord 2005 after it has been wrapped around the electronic device 2001. Note that in FIG. 20D, the cords for the speakers 2011 and 2012 do not include magnetic beads. Therefore, the speakers 2011 and 2012 are not coupled to each other and hang freely, as illustrated in FIGS. 20D and 20E.
In some embodiments, after the cord 2005 has been wrapped around the electronic device 2001, the magnetic strap 101 is formed into a loop (i.e., the first mode of operation). These embodiments are illustrated in FIGS. 20D, 20E, and 21A.
When deploying the cord 2005, the magnetic strap 101 flips back to the open position (i.e., the magnetic strap 101 lays substantially flat on the electronic device 210. This process for deploying the cord 2005 from the electronic device 2001 is illustrated in FIGS. 21A-21C, according to some embodiments. In FIG. 21A, a user grabs the speakers (or the cord 2005 near the speakers) and pulls the cord 2005 in a direction substantially parallel to the length of the magnetic strap 101. The force that the cord 2005 exerts against the magnets at the magnetic attachment points 104 and 105 causes the magnets to be detached from each other, as illustrated in FIG. 21B. In FIG. 21C, the cord 2005 is fully deployed from the magnetic strap 101.
Although the discussion above describes deploying a wrapped cord from the magnetic strap 101 by pulling on the cord in a direction substantially parallel to the length of the magnetic strap 101, in some embodiments, a wrapped cord is deployed from the magnetic strap 101 by pulling on the cord in a direction not parallel to the length of the magnetic strap 101. For example, if the magnetic strap 101 is detached from the electronic devices 210 and 2001, a user may deploy a wrapped cord by pulling in a direction perpendicular to the length of the magnetic strap. Alternatively, the user may also pull the magnetic attachment points 104 and 105 away from each other by pulling on the strap directly.
In some embodiments, the magnetic beads 302 and 303 are used to secure the cord 201 when the cord 201 is deployed. For example, FIG. 5A illustrates an end user 501 using the cord 201 with the electronic device 210, according to some embodiments. As illustrated in FIG. 5A, the cord 201 includes a cord segment 204 coupled to the speaker 202 and a cord segment 205 coupled to the speaker 203. Note that cord segments 204 and 205 may also be referred to as speaker cords. The cord segments 204 and 205 are coupled to the cord 201 at point 206. When the speakers 202 and 203 are inserted into the ears of the end user 501, the cord segments 204 and 205 may dangle loosely. If the end user is moving around (e.g., running, walking, etc.), the cord segments 204 and 205 may swing around and get caught in clothing and/or become dislodged from the ears of end user 501. To prevent the cord segments 204 and 205 from dangling, the magnetic beads 302 and 303 are moved to a position below the chin of the end user 501 and are magnetically coupled to each other, as illustrated in FIG. 5B. In the configuration illustrated in FIG. 5B, the end user 501 may slide the magnetic beads 302 and 303 up and down the cord segments 204 and 205 to adjust the amount of the cord segments 204 and 205 that are unsecured.
Although FIGS. 5A and 5B illustrate a partially-deployed cord 201, the cord 201 may also be fully-deployed. The fully-deployed cord is illustrated in FIGS. 5C and 5D, which are analogous to FIGS. 5A and 5B, respectively.
In some embodiments, at least one of the magnetic beads 301, 302, 303, and 304 include a clip that allows the magnetic bead to be clipped onto an object. For example, the object may be clothing (e.g., a shirt, a pants pocket, etc.) or a purse strap.
Option 3: Magnetic Strap and Magnetic Material
In some embodiments, to assist in the deployment of the cord 201, the magnetic material 103 is attached to the back of the electronic device 210 so that when the magnetic strap 101 is in the open position, the magnetic attachment point 105 of the magnetic strap 101 is magnetically attached to the magnetic material 103. These embodiments are illustrated in FIGS. 4A, 4B, and 4C. In FIG. 4A, an end user grabs the speakers and pulls the cord 201 in a direction substantially parallel to the length of the magnetic strap 101. The force that the cord 201 exerts against the magnets at the magnetic attachment points 104 and 105 causes the magnets to be detached from each other so that the magnetic strap 101 no longer forms the loop, as illustrated in FIG. 4B. The force that the cord 201 exerts against the magnets causes the magnetic strap 101 to return to its natural configuration (e.g., the flat configuration). The magnetic strap 101 is also magnetically attracted to the magnetic material 103, thereby assisting in the deployment of the magnetic strap 101. In other words, the magnetic force between the magnetic attachment point 105 of the magnetic strap 101 and the magnetic material 103 pulls the magnetic attachment point 105 towards the magnetic material 103. The magnetic material 103 also holds the magnetic strap 101 to the electronic device 210 so that the strap does not move while in the open position. In FIG. 4C, the cord 201 is fully deployed from the magnetic strap 101. After the cord 201 is fully deployed, the end user may fold the strap over, as illustrated in FIG. 4D.
In some embodiments, the magnetic material 103 is attached to the electronic device 210 so that when the magnetic strap 101 is in the open position, the magnetic attachment point 104 of the magnetic strap 101 is magnetically attached to the magnetic material 103. These embodiments are used to attach the magnetic strap 101 to the electronic device 210 when the magnetic strap 101 is folded into the loop configuration.
Note that the magnetic material may be attached to the electronic device 210 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 210, a back panel of the electronic device 210, and/or a case or a skin for the electronic device 210. Furthermore, that the magnetic material may be substituted for an adhesive applied to either or both of the electronic device 210 and/or the magnetic strap 101, suction devices (e.g., suction cups) attached to either or both of the electronic device 210 and/or the magnetic strap 101, Velcro attached to both the electronic device 210 and the magnetic strap 101, van der Waals force attachment mechanisms (e.g., “Gecko” tape) attached to either or both of the electronic device 210 and/or the magnetic strap 101, snaps attached to either or both of the electronic device 210 and/or the magnetic strap 101, buttons attached to either or both of the electronic device 210 and/or the magnetic strap 101, and hinges attached to either or both of the electronic device 210 and/or the magnetic strap 101.
Option 4: Magnetic Strap, Magnetic Beads, and Magnetic Material
In some embodiments, the cord management system 100 includes the magnetic strap 101, the magnetic beads 102, and the magnetic material 103. The various embodiments described above may be used in combination to secure the cord 201.
The design and the composition of magnetic strap 101, the magnetic beads 102, and the magnetic material 103 are described in more detail below.
Option 5: Magnetic Beads
In some embodiments, the cord management system 100 includes the magnetic beads 102. In these embodiments, the magnetic beads are attached to the cord 201 at locations so that when the cord 201 is wrapped around an object (e.g., the electronic device 210), two or more magnetic beads at different locations on the cord 201 are magnetically attached to each other so that the cord 201 cannot become unwrapped from the object. For example, FIG. 3G illustrates magnetic beads 302, 303, and 304 (all of which are located at different locations on the cord 201) are magnetically attached to each other.
Magnetic Straps
FIGS. 6A, 6B, and 6C illustrate top, perspective and side views, respectively, of a magnetic strap 601, according to some embodiments. Note that the magnetic strap 601 is one particular embodiment of the magnetic strap 101 described above. In some embodiments, the magnetic strap 601 includes a magnet 602 at a location 604 on the magnetic strap 601 and a magnet 603 at a location 605 on the magnetic strap 601. The magnets 602 and 603 may include any element or composition that is capable of producing a magnetic field. For example, the magnets 602 and 603 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 602 and 603 are Neodymium magnets. In some embodiments, the Neodymium magnets are a grade N42.
In some embodiments, the magnetic strap 601 includes only one magnet and a magnetic material. For example, the magnetic strap 601 may include the magnet 602 at the location 604 and a magnetic material at the location 605. Alternatively, the magnetic strap 601 may include a magnetic material at the location 604 and the magnet 603 at the location 605. 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. Also note that this specification refers to the magnets 602 and 603 as “magnets” even though one of the magnets 602 and 603 may be a magnetic material. Furthermore, any combination of magnets and magnetic material that allows for the magnetic attachments described herein to function may be used.
In some embodiments, the magnets 602 and 603 are solid magnets. In some embodiments, the magnets 602 and 603 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 602 and 603 are sets of magnets. The selection of the size and shape of the magnets 602 and 603 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 magnetic strap 601.
In some embodiments, the magnets 602 and 603 are embedded in the magnetic strap 601. In these embodiments, the magnets 602 and 603 are either enclosed or partially enclosed by the material that forms the magnetic strap 601. As illustrated in FIG. 6C, the material that forms the magnetic strap 601 forms a gradual contour around the magnets 602 and 603. The contour formed by the material of the magnetic strap 601 around the magnets 602 and 603 may conform to the shape of the magnetic strap 601. For example, as illustrated in FIGS. 6A-6C, the material enclosing the magnets 602 and 603 forms a rectangular region. This rectangular region serves at least two purposes: to hold the magnets 602 and 603 in place and to provide a flat surface onto which the magnets 602 and 603 can be magnetically attached to each other. Note that the flat surface allows the magnets 602 and 603 to be magnetically attached to each other better than a surface that is not flat (e.g., a crowned surface).
In some embodiments, the magnets 602 and 603 are configured so that opposite magnetic poles of each magnet are perpendicular to the top (or bottom) surface of the magnetic strap 601. For example, the north pole of the magnet 602 is configured to be perpendicular to a first surface of the magnetic strap 601 whereas the south pole of the magnet 603 is configured to be perpendicular to the first surface of the magnetic strap 601. In other embodiments, and as noted above, only one of the magnets 602 and 603 is a magnet and the other magnet is a magnetic material. Again, any combination of magnets and magnetic material that allows for the magnetic attachments described herein to function may be used.
In some embodiments, the magnetic strap 601 includes a segment 606 that is located between the magnets 602 and 603. In some embodiments, the segment 606 also includes the portion of the magnetic strap 601 that includes the magnets 602 and 603. In some embodiments, the segment 606 is composed of a material that is substantially memoryless. In some embodiments, the memoryless material is an elastic polymer. A material that is memoryless is a material that does not exhibit elastic hysteresis, which causes a material to behave differently when a loading force that was exerted on the material is removed. In the case of a material that does not have elastic hysteresis, the application of a loading force and a subsequent removal of the loading force does not cause the material to “remember” that the material was previously loaded. Thus, the material returns to its original shape and/or configuration when the loading force is removed. In some embodiments, the segment 606 is composed of a memoryless material that causes the magnetic strap 601 to return to a substantially flat configuration when unloaded (or when the loading force is less than a restoring force of the memoryless material). These embodiments are illustrated in FIGS. 6A-6C. Note that when an external force is applied to the memoryless material, the memoryless material generates a restoring force that opposes the external force. In other words, the restoring force tries to keep the memoryless material in its natural configuration (e.g., a flat configuration). For example, consider the application of an external force to the segment 606 that causes the segment 606 to form a loop. When the external force is removed, the segment 606 returns to its natural configuration (e.g., as illustrated in FIGS. 6A-6C). In some embodiments, the restoring force is a function of the displacement (e.g., stretching, bending, etc.) of the memoryless material. In these embodiments, the external force required to change the configuration of the memoryless material varies as a function of the displacement.
In some embodiments, the segment 606 is composed of a polymer. In some 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. The type of manufacturing process selected may depend on factors such as a desired manufacturing volume, manufacturing time, and manufacturing costs. Additionally, the type of manufacturing process selected may depend on a desired aesthetic design of the magnetic strap 601. For example, if the aesthetic design of the magnetic strap 601 requires that the magnets 602-603 are to be encapsulated in the material of the magnetic strap 601, an injection molding process may be used. In some embodiments, a two-shot injection molding process is used to manufacture the magnetic strap 601.
In some embodiments, the segment 606 is composed of a fabric. For example, the fabric may be a Neoprene fabric, leather, silk, cotton, denim, foil, Mylar, and the like.
In some embodiments, the magnetic strap 601 includes a segment 607. In some embodiments, the segment 607 includes the portion of the magnetic strap 601 that includes the magnet 603. In some embodiments, the segment 607 is composed of an elastic material. The elastic polymer may be any of the polymers discussed above with respect to the segment 606. In some embodiments, the segment 607 is composed of a fabric (e.g. Neoprene).
In some embodiments, the segment 607 includes a handle 610. In some embodiments, the handle 610 is formed from the same material as the segment 607. The handle 610 is a raised portion or high friction of material of the magnetic strap 601 that allows a user to grab onto the end of the magnetic strap 601 while attaching the magnetic strap 601 to a cord (or connector) using the cord-attachment mechanism 609. Without the handle 610, the fingers of the end user may slip off of the magnetic strap 601 while attaching the magnetic strap 601 to a cord (and/or a connector of the cord) using the cord-attachment mechanism 609. A high friction surface for the handle 610 may be created
In some embodiments, the magnetic strap 601 includes a segment 608. In some embodiments, the segment 608 includes the portion of the magnetic strap 601 that includes the magnet 602. In some embodiments, the segment 608 is composed of an elastic material. In some embodiments, the elastic material is an elastic polymer. The elastic polymer may be any of the polymers discussed above with respect to the segment 606. In some embodiments, the segment 608 is composed of a fabric (e.g., Neoprene).
In some embodiments, the segments 606, 607, and 608 are composed of the same polymer. In some embodiments, the segments 606, 607, and 608 are composed of different, but compatible, polymers. In some embodiments, the segment 608 is composed of a fabric.
In some embodiments, the segment 607 includes a cord-attachment mechanism 609 that is used to attach the magnetic strap 601 to a cord (and/or a connector of the cord). The cord attachment mechanism is described in more detail below with respect to FIGS. 10 and 11.
In some embodiments, the magnetic strap 601 operates in at least two modes of operation, as described above. In a first mode of operation, the magnets 602 and 603 are magnetically attached to each other so that the segment 606 of the magnetic strap 601 located between the magnets 602 and 603 forms a loop configured to secure a cord that is wrapped around the magnetic strap 601 (e.g., see FIG. 2B). In the first mode of operation, the attractive magnetic force between the magnets 602 and 603 is greater than any restoring force exerted by the material of the magnetic strap 601 that causes the magnetic strap 601 to return to its natural configuration (e.g., flat configuration). Thus, the segment 606 remains in a loop until an external force is applied to the segment 606 that causes the magnets 602 and 603 to be magnetically detached and/or otherwise separated from each other. In a second mode of operation, the magnets 602 and 603 are magnetically detached and/or otherwise separated from each other (e.g., the magnets 602 and 603 are no longer attached to each other). For example, in the second mode of operation, the magnetic strap 601 may be substantially flat (e.g., see FIGS. 6A, 6B, and 6C).
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. Thus, in some embodiments, the strength of the magnets 602 and 603 are selected so that the magnetic force between the magnets 602 and 603 is greater than any restoring force exerted by the material of the magnetic strap only when the magnets 602 and 603 are a predefined distance from each other. When the magnets 602 and 603 are at a distance greater than the predefined distance from each other, the magnetic force between the magnets 602 and 603 is less than the restoring force exerted by the material. Thus, the magnetic strap 601 returns to its natural configuration (e.g., the flat configuration illustrated in FIGS. 6A-6C). When the magnets 602 and 603 are at a distance less than or equal to the predefined distance from each other, the magnetic force between the magnets 602 and 603 exceeds the restoring force exerted by the material. Thus, the magnets 602 and 603 are drawn to each other and become magnetically attached to each other.
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. For example, even though the material of the magnetic strap 601 (e.g., an elastic polymer) may enclose the magnets 602 and 603, the magnets 602 and 603 are magnetically attached to each other when the surface(s) of material enclosing the magnets 602 and 603 touch each other.
In some embodiments, the second mode of operation is used when deploying (e.g., unwrapping) a cord that is wrapped around the magnetic strap 601. These embodiments are discussed above with respect to FIGS. 2H-2K.
In some embodiments, the second mode of operation is used when wrapping a cord around the magnetic strap 601. In some embodiments, the cord is wrapped substantially perpendicular to and/or otherwise across the magnetic strap 601 at any angle (e.g., see FIGS. 2A-2B).
In some embodiments, the second mode of operation is used when a user uses the cord. For example, if the cord is a cord for headphones and the magnetic strap 601 is attached to a music player, the user may use the deployed cord to listen to music.
In some embodiments, the length of the segment 607 and the location of the cord-attachment mechanism 609 within the segment 607 are selected so that when the magnetic strap 601 is placed on an object, the segment 606 lies flat on a surface of the object (e.g., a portable electronic device) (e.g., see FIG. 2A).
In some embodiments, the length of the magnetic strap 601 is selected based on one or more of: a range of lengths of cords that are to be secured using the magnetic strap 601, a range of thicknesses of cords that are to be secured using the magnetic strap 601, a number of times the cord will wrap around the magnetic strap 601, dimensions of objects on which the magnetic strap 601 is to be placed, the location of the magnets 602 and/or 603, whether a case is used, and a number of times the cord will wrap around the magnetic strap 601 and an object (and a case for the object). In some embodiments, the minimum length of the magnetic strap 601 is 1.5 inches. In some embodiments, the length of the magnetic strap 601 is between 1.5 inches and 3.19 inches. In some embodiments, the length of the magnetic strap 601 is 3.02 inches.
Note that the width of the magnetic strap 601 is typically bounded by the minimum manufacturable width of the material used in the magnetic strap 601. However, the actual width used for the magnetic strap 601 is typically selected to be at least the size (e.g., the diameter) of the magnets 602 and 603 in embodiments in which the magnets are embedded in the magnetic strap 601. In embodiments in which the magnets 602 and 603 are attached to the magnetic strap 601 by other means, the magnetic strap 601 may be narrower than the magnets 602 and 603. The width of the magnetic strap 601 also affects the resistance of the magnetic strap 601 to twisting (or torsional) forces about a longitudinal axis (i.e., the length) of the magnetic strap 601. For example, if the magnetic strap 601 is wider, the magnetic strap 601 has less tendency to twist (e.g., when deploying a cord). In some embodiments, the width of the magnetic strap 601 is between 0.25 inches and 0.52 inches. In some embodiments, the width of the magnetic strap 601 is 0.51 inches. In some embodiments, the width of the magnetic strap 601 is at least 0.25 inches.
The thickness of the magnetic strap 601 is typically bounded by the minimum manufacturable thickness of the material used in the magnetic strap 601. The thickness of the magnetic strap 601 also affects the resistance of the magnetic strap 601 to twisting (or torsional) forces about a longitudinal axis (i.e., the length) of the magnetic strap 601. For example, if the magnetic strap 601 is wider, the magnetic strap 601 has less tendency to twist (e.g., when deploying a cord). In some embodiments, the thickness of the magnetic strap 601 is between 0.01 inches and 0.19 inches. In some embodiments, the minimum thickness of the magnetic strap 601 is 0.01 inches. In some embodiments, the thickness of the magnetic strap 601 in the center of the segment 606 is 0.06 inches. In some embodiments, the thickness of the magnetic strap 601 enclosing the magnets 602 and 603 is 0.11 inches.
In some embodiments, the strength of the magnets 602 and 603 are selected to provide a predefined attractive magnetic force between the magnets 602 and 603 when the magnet 602 is magnetically attached to the magnet 603. When the magnet 602 is magnetically attached to the magnet 603 and a decoupling force (e.g., an external force) that is less than the predefined threshold is exerted against the predefined attractive magnetic force between the magnets 602 and 603, the magnets remains magnetically attached to each other. When the magnet 602 is magnetically attached to the magnet 603 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 are magnetically detached from each other.
The predefined threshold is a function of several factors. These factors include the strengths, size, number, shape, and surface area of the magnets 602 and 603, the material of the magnetic strap 601, and the type of decoupling force exerted against the magnets 602 and 603. The strengths of the magnets 602 and 603 determine the strength of the attractive magnetic force between the magnets 602 and 603. As described above, the strength of the attractive magnetic force between the magnets 602 and 603 is a function of the distance between the magnets 602 and 603. Thus, the closer the magnets 602 and 603 are to each other, the stronger the attractive magnetic force. The material of the magnetic strap 601, the material of the cord wrapped within the magnetic strap 601, the length of the cord, the diameter of the cord, and the number of loops of the cord that are wrapped within the magnetic strap 601, and the thickness of the magnetic strap 601 determine the magnitude of the restoring force. As described above, the magnitude of the restoring force may be a function of the displacement of the material. For example, the restoring force may be greater when the material of the magnetic strap is folded over so that the magnets 602 and 603 are magnetically attached to each other than if the material were only bent slightly. The type of decoupling force exerted against the magnets 602 and 603 may include an impulse force (or a force applied during a short but finite time interval) and a continuous force that is either constant or variable.
For a decoupling force that is continuously exerted against the attractive magnetic force between the magnets 602 and 603, the decoupling force required to detach the magnets 602 and 603 so that they do not become magnetically attached again is a function of the distance between the magnets 602 and 603 and of the restoring force of the material of the magnetic strap 601. As the distance between the magnets 602 and 603 increases, the attractive magnetic force decreases and the decoupling force required is decreased. When a predetermined distance between the magnets 602 and 603 is reached, the restoring force of the material of the magnetic strap 601 exceeds the attractive magnetic force. At this point, the magnets 602 and 603, while still magnetically coupled to each other, cannot pull the magnets 602 and 603 back together. Accordingly, the decoupling force is no longer necessary because the restoring force of the material of the magnetic strap 601 causes the magnetic strap 601 to return to its natural configuration. An example of a decoupling force that is continuously exerted is a force that is generated by a hand that is pulling the magnets 602 and 603 apart from each other.
For a decoupling force that is an impulse (or that is applied during a short but finite time interval) exerted against the attractive magnetic force between the magnets 602 and 603, the decoupling force required to detach the magnets 602 and 603 so that they do not become magnetically attached again must impart at least enough momentum to the magnets 602 and/or 603 such that distance between the magnets 602 and 603 reaches the predetermined distance at which the restoring force of the material of the magnetic strap 601 exceeds the attractive magnetic force. For example, consider a decoupling force that is an impulse that does not impart enough momentum to the magnets 602 and/or 603 such that the distance between the magnets 602 and 603 reaches the predetermined distance. After the decoupling force is applied and the magnets 602 and 603 are detached from each other, the attractive magnetic force between the magnets 602 and 603 act against the imparted momentum and slows the parting magnets 602 and 603 until the momentum of the magnets 602 and/or 603 reaches zero. Since the magnets 602 and 603 have not reached the predetermined distance by the time the momentum of the magnets 602 and/or 603 reaches zero, the attractive magnetic force pulls the magnets 602 and 603 back toward each other so that they become magnetically attached again. An example of a decoupling force that is an impulse is a force generated when a wrapped cord is pulled away from the magnetic strap 601 (e.g., see FIGS. 2H-2K).
In some embodiments, each of the magnets 602 and 603 are Neodymium donut-shaped magnets having a grade of N42, an outer diameter of 0.375 inches, an inner diameter of 0.125 inches, and a thickness of 0.0625 inches. In some embodiments, the thickness of the magnets 602 and 603 is between 0.0625 inches and 0.2 inches. In some embodiments, the diameter of the magnets 602 and 603 are between 0.3 inches and 0.375 inches. 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. Also note that the effective magnetic strength of the magnets may be affected by the properties of the material of the magnetic strap 601. For example, if the magnets 602 and 603 are encapsulated in a thicker material, the effective magnetic strength of the magnets 602 and 603 is reduced. Similarly, if the magnets 602 and 603 are encapsulated in a material that suppresses or otherwise impedes a portion of the magnetic fields from the magnets 602 and 603, the effective magnetic strength of the magnets 602 and 603 is reduced. Furthermore, note that the selection of the magnetic strength of the magnets 602 and 603 also depends on the elasticity of the material used for the magnetic strap 601. For example, when a less elastic material (i.e., a more rigid material) is used in the magnetic strap 601, the restoring force of the elastic material is greater (i.e., the material is more rigid and resists changes to its natural configuration) and stronger magnets are required to hold the magnets 602 and 603 together.
In some embodiments, each of the magnets 602 and 603 are Neodymium step-shaped (e.g., step-layered) magnets.
In some embodiments, the location and the distance of the magnets 602 and 603 on the magnetic strap 601 is determined based at least in part on the length of the strap, the type of objects onto which the magnetic strap is to be used, the elasticity of the material of the magnetic strap 601, and a length of a cord. In some embodiments, the minimum distance between the magnets 602 and 603 on the magnetic strap 601 is 0.5 inches. In some embodiments, the distance between the magnets 602 and 603 is between 0.5 inches to 2.1 inches. In some embodiments, the distance between the magnets 602 and 603 is 1.38 inches.
In some embodiments, the durometer (i.e., the hardness, also referred to as the “Shore durometer”) of the material of the magnetic strap 601 is at least 10. In some embodiments, the durometer of the material of the magnetic strap 601 in the segments 607 and 608 is 40 and the durometer of the material of the magnetic strap 601 in the segment 606 is 60. In some embodiments, the durometer of the material of the magnetic strap 601 in the segments 607 and 608 is 20 and the durometer of the material of the magnetic strap 601 in the segment 606 is 60. In some embodiments, the durometer of the material of the magnetic strap 601 in the segments 607 and 608 is 20 and the durometer of the material of the magnetic strap 601 in the segment 606 is 40.
Thus, the selection of material for the magnetic strap 601 (e.g., the segments 606-608) and the selection of the strengths, size, number, the distance between the magnets 602 and 603, shape, and surface area of the magnets 602 and 603 depends on the aforementioned factors. Furthermore, the selection of the materials for the magnetic strap 601 and the strengths of the magnets 602 and 603 are based on factors including the ease of deployment of the cord (e.g., the amount of force required to free the cord from the magnetic strap 601, etc.) and the prevention of the accidental deployment of the cord (e.g., from jostling in a bag or a purse, a pocket, etc.).
In some embodiments, the location 605 is selected so that when a connector for a cord is inserted into the cord-attachment mechanism 609 and the connector is inserted into an electronic device, the magnetic strap 601 lies substantially flat on the electronic device.
Note that although the discussion of the magnetic strap 601 refers to the magnet 602 and the magnet 603, each of the magnets 602 and 603 may include a set of magnets. Also note that, one of the magnets 602 and 603 may be replaced with a magnetic material, as described above. In some embodiments, the magnet 602 and the magnet 603 are replaced with an attachment mechanism selected from the group consisting of Velcro, adhesives, suction cups, and a van der Waals force attachment mechanism.
FIGS. 7A, 7B, and 7C illustrate top, perspective, and side views, respectively, of a magnetic strap 701, according to some embodiments. The magnetic strap 701 is similar to the magnetic strap 601, so only the differences are discussed. The magnetic strap 701 includes a magnet 702 at a location 704 on the magnetic strap 701 and a magnet 703 at a location 705 on the magnetic strap 701. The magnetic strap 701 also includes a cord-attachment mechanism 709.
In some embodiments, the magnets 702 and 703 are embedded in the magnetic strap 701. In these embodiments, the magnets 702 and 703 are either enclosed or partially enclosed by the material that forms the magnetic strap 701. As illustrated in FIG. 7C, the material that forms the magnetic strap 701 forms a gradual contour around the magnets 702 and 703. The contour formed by the material of the magnetic strap 701 around the magnets 702 and 703 may conform to the shape of the magnetic strap 701. For example, as illustrated in FIGS. 7A-7C, the material enclosing the magnets 702 and 703 forms a gradual contour from the center of the magnets 702 and 703 to the center of the segment 706. Thus, in contrast to the flat surface above the magnets 602 and 603 illustrated in FIGS. 6A-6C, a crown is formed at the center of the magnets 702 and 703. Although the crown may be more aesthetically appealing, the crown reduces the surface area on which the magnets 702 and 703 can be magnetically attached to each other such that magnets of greater magnetic strength may be required.
In some embodiments, the magnetic strap 701 includes a segment 706 that is located between the magnets 702 and 703. In some embodiments, the segment 706 also includes the portion of the magnetic strap 701 that includes the magnets 702 and 703. In some embodiments, the segment 706 is composed of a material that is substantially memoryless, as discussed above with respect to the segment 606 in FIGS. 6A-6C.
In some embodiments, the magnetic strap 701 includes a segment 707. In some embodiments, the segment 707 includes the portion of the magnetic strap 701 that includes the magnet 703. In some embodiments, the segment 707 is composed of an elastic material, as discussed above with respect to the segment 607 in FIGS. 6A-6C. In some embodiments, the segment 707 is composed of an elastic polymer.
In some embodiments, the magnetic strap 701 includes a segment 708. In some embodiments, the segment 708 includes the portion of the magnetic strap 701 that includes the magnet 702. In some embodiments, the segment 708 is composed of an elastic material, as discussed above with respect to the segment 608 in FIGS. 6A-6C. In some embodiments, the segment 708 is composed of an elastic polymer.
In some embodiments, the segment 707 includes a cord-attachment mechanism that is used to attach the magnetic strap 701 to a cord (and/or a connector for the cord), as described above with respect to the cord-attachment mechanism 609 in FIGS. 6A-6C.
FIGS. 8A, 8B, and 8C illustrate top, perspective, and side views, respectively, of a magnetic strap 801, according to some embodiments. The magnetic strap 801 is similar to the magnetic strap 601, so only the differences are discussed. The magnetic strap 801 includes magnets 802 and 804 at a location 806 on the magnetic strap 801 and magnets 803 and 805 at a location 807 on the magnetic strap 801. In some embodiments, the magnets 802-805 are attached to the surface of the magnetic strap 801. In some embodiments, the material of the magnetic strap 801 covers all but one surface of the magnets 802-805 (e.g., see FIGS. 8D and 8E). In some embodiments, the material of the magnetic strap 801 covers all of the surfaces of the magnets 802-805. Note that although the discussion of the magnetic strap 801 refers to the magnets 802, 803, 804, and 805, each of the magnets 802, 803, 804, and 805 may include a set of magnets.
In some embodiments, the magnets 802, 803, 804, and 805 are configured so that for a given surface of the magnetic strap 801, opposite magnetic poles of each magnet on the surface of the magnetic strap 801 are perpendicular to the surface of the magnetic strap 601. For example, the north pole of the magnet 802 is configured to be perpendicular to a top surface of the magnetic strap 801, whereas the south pole of the magnet 803 is configured to be perpendicular to the top surface of the magnetic strap 801. Similarly, the south pole of the magnet 804 is configured to be perpendicular to the bottom surface of the magnetic strap 801, whereas the north pole of the magnet 805 is configured to be perpendicular to the bottom surface of the magnetic strap 801. Note that the directions of the poles of the magnets may be reversed.
In some embodiments, the magnets 802 and 804 are a single magnet and the magnets 803 and 805 are a single magnet.
In some embodiments, the magnetic strap 801 includes a segment 808 that is located between the magnets 802 and 804 and the magnets 803 and 805. In some embodiments, the segment 808 also includes the portion of the magnetic strap 801 that includes the magnets 802-805. In some embodiments, the segment 808 is composed of a material that is substantially memoryless, as discussed above with respect to the segment 606 in FIGS. 6A-6C.
In some embodiments, the magnetic strap 801 includes a segment 809. In some embodiments, the segment 809 includes the portion of the magnetic strap 801 that includes the magnets 803 and 805. In some embodiments, the segment 809 is composed of an elastic material, as discussed above with respect to the segment 607 in FIGS. 6A-6C. In some embodiments, the segment 809 is composed of an elastic polymer.
In some embodiments, the magnetic strap 801 includes a segment 811. In some embodiments, the segment 811 includes the portion of the magnetic strap 801 that includes the magnets 802 and 804. In some embodiments, the segment 811 is composed of an elastic material, as discussed above with respect to the segment 608 in FIGS. 6A-6C. In some embodiments, the segment 811 is composed of an elastic polymer.
In some embodiments, the cross section of the magnets 802, 803, 804, and 805 are step-shaped (i.e., step-layered). These embodiments are illustrated in FIG. 8D. In these embodiments, the base of the magnet has protrusions (e.g., protrusions 821, 822, 823, 824) that form a step. The protrusions of the magnets 802, 803, 804, and 805 may be inserted into corresponding holes (or pockets) in the material so that the magnets 802, 803, 804, and 805 are secured to the magnetic strap 801. Note that as discussed above, the material of the magnetic strap 801 may cover all but one surface of the magnets 802-805. Alternatively, the material of the magnetic strap 801 may cover all of the surfaces of the magnets 802-805.
In some embodiments, the magnets 802 and 804, and 803 and 805, respectively, include posts that are configured to be inserted into each other through the magnetic strap 801. These embodiments are illustrated in FIG. 8E. In these embodiments, the magnetic strap 801 has a hole at the locations 806 and 807 into which the posts of the magnets 802 and 804, and 803 and 805 (e.g., post 831 for the magnet 803 and post 832 for the magnet 805) for respectively, are inserted. The posts of the magnets 802 and 804, and 803 and 805, respectively, may be configured to be locked to each other after being attached to the magnetic strap 801.
In some embodiments, the segment 809 includes a cord-attachment mechanism that is used to attach the magnetic strap 801 to a cord (and/or a connector for the cord), as described above with respect to FIGS. 6A-6C.
FIGS. 9A, 9B, and 9C illustrate top, perspective, and side views of a magnetic strap 901, according to some embodiments. The magnetic strap 901 is similar to the magnetic strap 601, so only the differences are discussed. The magnetic strap 901 includes a magnet 902 at a location 904 on the magnetic strap 901 and a magnet 903 at a location 905 on the magnetic strap 901. In some embodiments, the magnets 902 and 903 are either embedded or partially embedded in the magnetic strap 901. In these embodiments, the material of the magnetic strap 901 that encloses the magnets 902 and 903 conforms (i.e., fitted) to the shape of the magnets 902 and 903. Note that although the discussion of the magnetic strap 901 refers to the magnets 902 and 903, each of the magnets 902 and 903 may include a set of magnets.
In some embodiments, the magnets 902 and 903 are configured so that opposite magnetic poles of each magnet are perpendicular to the top (or bottom) surface of the magnetic strap 901. For example, the north pole of the magnet 902 is configured to be perpendicular to a first surface of the magnetic strap 901 whereas the south pole of the magnet 903 is configured to be perpendicular to the first surface of the magnetic strap 901.
In some embodiments, the magnetic strap 901 includes a segment 906 that is located between the magnet 902 and the magnet 903. In some embodiments, the segment 906 also includes the portion of the magnetic strap 901 that includes the magnets 902 and 903. In some embodiments, the segment 906 is composed of a material that is substantially memoryless, as discussed above with respect to segment 606 in FIGS. 6A-6C.
In some embodiments, the magnetic strap 901 includes a segment 907. In some embodiments, the segment 907 includes the portion of the magnetic strap 901 that includes the magnet 903. In some embodiments, the segment 907 is composed of an elastic material, as discussed above with respect to the segment 607 in FIGS. 6A-6C. In some embodiments, the segment 907 is composed of an elastic polymer.
In some embodiments, the magnetic strap 901 includes a segment 908. In some embodiments, the segment 908 includes the portion of the magnetic strap 901 that includes the magnet 902. In some embodiments, the segment 908 is composed of an elastic material, as discussed above with respect to the segment 608 in FIGS. 6A-6C. In some embodiments, the segment 908 is composed of an elastic polymer.
In some embodiments, the segment 907 includes a cord-attachment mechanism that is used to attach the magnetic strap 901 to a cord (and/or a connector for the cord), as described above with respect to the cord-attachment mechanism 609 in FIGS. 6A-6C.
As discussed above, the magnetic straps 601, 701, 801, and 901 use magnets and/or a combination of magnets and magnetic material to form a loop that is configured to secure a cord. However, other attachment mechanisms may be used to form the loop. In some embodiments, the attachment mechanism is selected from the group consisting of adhesive, Velcro, snaps, buttons, buckles, beads, and van der Waals force attachment mechanisms, suction devices (e.g., suction cups), springs, bistable springs (e.g., a slap bracelet), sleeves that insert into slots, pegs that are inserted into holes, and hinges.
FIGS. 12A-12F illustrate magnetic straps 1201-1206, respectively, which are alternative designs of the magnetic strap 601 (701, 801, or 901), according to some embodiments. The magnetic straps 1201-1206 illustrated in these figures differ only in the shapes of the ends of the straps. These alternative designs may also be applied to the magnetic straps 601, 701, 801, and 901 illustrated in FIGS. 6-9, respectively.
In some embodiments, the thickness of the material of the magnetic strap 601 (701, 801, or 901) from the edge magnets gradually decreases to the thickness of the magnetic strap 601 at the center of the sections 606, 706, 808, or 906. In some embodiments, the thickness of the material of the magnetic strap 601 from the edge magnets gradually decreases to the thickness of the magnetic strap 601 a predetermined location in the sections 606, 706, 808, or 906. In these embodiments, the thickness of the magnetic strap 601 from the predetermined location in the sections 606, 706, 808, or 906 to the center of the sections 606, 706, 808, or 906 is constant. By adjusting the predetermined location, the flexibility of the magnetic strap 601 may be increased or decreased. For example, if the predetermined location is closer to the magnets, the magnetic strap 601 is more flexible because the magnetic strap 601 is thinner in the sections 606, 706, 808, or 906. However, if the predetermined location is at the center of the sections 606, 706, 808, or 906, the magnetic strap 601 is less flexible because the magnetic strap 601 is thicker in the sections 606, 706, 808, or 906.
In some embodiments, the material enclosing the magnets of the magnetic strap 601 (801, or 901) forms a substantially flat surface over the top and the bottom of the magnets. In these embodiments, the substantially flat surface increases the surface area on which the magnets can be magnetically coupled to each other, and in turn, increases the magnetic coupling force between the magnets as compared to a crowned surface (e.g., as illustrated in FIG. 7C).
Note that although the embodiments described herein encapsulate the magnets in the material of the magnetic strap 601 (701, 801, or 901), the magnets may also be attached (e.g., using an adhesive, bolts, rivets, or other attachment mechanisms) onto one or more faces of the magnetic strap 601 (e.g., the “top” side or the “bottom” side of the magnetic strap 601).
In some embodiments, the magnetic straps 601, 701, 801, and 901 are symmetrical. In these embodiments, the magnetic straps 601, 701, 801, and 901 may be folded over on either surface to form the loop. In some embodiments, the magnetic straps 601, 701, 801, and 901 are asymmetrical. In these embodiments, the magnetic straps 601, 701, 801, and 901 may only be folded on one of the surfaces to form the loop. In some embodiments; one surface of the magnetic straps 601, 701, 801, and 901 have a high-friction coating to help hold the wrapped cord in the strap and one surface of the magnetic straps 601, 701, 801, and 901 have a low-friction coating to ease removal of the strap from an object.
Note that any combination of the features of the magnetic straps described above with respect to FIGS. 6-9 may be used in a particular implementation of a magnetic strap.
Cord-Attachment Mechanism
As described above, the cord-attachment mechanisms 609, 709, 810, and 909 allow the magnetic straps 601, 701, 801, and 901, respectively, to be attached to a cord (and/or a connector for the cord). Although the following discussion of cord-attachment mechanisms refers to the cord-attachment mechanism 609, the embodiments described below may be applied to the cord-attachment mechanisms 709, 810, and 909. FIGS. 10 and 11 illustrate exemplary embodiments of the cord-attachment mechanism 609.
FIG. 10A illustrates the cord-attachment mechanism 609 as having a plurality of slits 1001, according to some embodiments. FIG. 10B illustrates the cord-attachment mechanism 609 as having a single slit 1002, according to some embodiments.
FIG. 10C illustrates the cord-attachment mechanism 609 as having two slits 1003 configured as an “X” or a “+,” according to some embodiments. Note that the angle between the two slits 1003 may be arbitrarily set. FIG. 10E illustrates the cord-attachment mechanism 609 as having slits 1005 in the shape of a star, according to some embodiments. The dimensions of the slits 1001, 1002, 1003, and 1005 are selected so that when a cord is inserted into the slits 1001, 1002, 1003, and 1005, the material around the respective slits applies a pressure against the cord and hold the cord to the magnetic strap 601. Furthermore, the dimensions of the slits 1001, 1002, 1003, and 1005 are selected so that the cord-attachment mechanism 609 can attach to cords (or connectors of cords) of varying sizes. After the magnetic strap 601 has been attached to the cord (or a connector of the cord), a predetermined elastic force exerted by the hole against the cord secures the magnetic strap 601 to the cord (or the connector of the cord).
FIG. 10D illustrates the cord-attachment mechanism 609 as a hole 1004 (e.g., a circular hole) in the segment 607, according to some embodiments. In these embodiments, a cord (or a connector of the cord) may be inserted into the hole. For embodiments in which the segment 607 is elastic, the hole expands as the cord (or the connector for the cord) is inserted into the hole. In some embodiments, the cord-attachment mechanism 609 is formed from an elastic polymer (e.g., by injecting an elastic polymer into a mold for the magnetic strap 601 or by cutting material from the segment 607, etc.). For example, the elastic polymer may be the elastic polymers described above with respect to the segment 607: In some embodiments, the cord-attachment mechanism 609 is composed of the same polymer as the segments 606, 607, and 608. In some embodiments, the cord-attachment mechanism is composed of different, but compatible, polymers. Note that the diameter of the hole 1004 may be determined based on factors including the range of diameters for cords and/or connectors for the cords to be used with the magnetic strap 601.
FIGS. 11A and 11B illustrate a side view and a perspective view, respectively, of a grommet 1101 for the cord attachment mechanism 609, according to some embodiments. The grommet 1101 increases the surface area in contact with a cord (or a connector for the cord) to reduce the tendency of the cord-attachment mechanism 609 to move up and/or down a cord (or a connector for the cord) and to prevent the material in section 607 from forming a cone shape when installing and/or using the magnetic strap 601. In some embodiments, the grommet has a height of 0.158 inches. In some embodiments, the grommet has a diameter of 0.1 inches.
FIG. 11C illustrates another grommet 1102 for the cord attachment mechanism 609, according to some embodiments. The grommet 1102 includes a centrally-located hole and slits coming out of the hole. The slits allow the grommet 1102 to expand to fit larger diameter cords (or connectors).
Note that other cord-attachment mechanisms may be used instead of the hole. For example, Velcro, adhesives, magnetic beads, suction devices, van der Waals force attachment mechanisms, buttons, buckles, springs, bistable springs (e.g., a slap bracelet), sleeves that insert into slots, pegs that are inserted into holes, hinges a molded strap with snaps may be used.
Magnetic Beads
FIGS. 13A and 13B illustrate top and side views, respectively, of a magnetic bead 1301, according to some embodiments. The magnetic bead 1301 includes a leg 1302 and a leg 1303 that are pivotally coupled to each other at one end of each respective leg. Each of the legs 1302 and 1303 also includes a free end. As illustrated in FIGS. 13A and 13B, the leg 1302 and the leg 1303 are formed from a single piece of material (e.g., a flexible material that allows the legs 1302 and 1303 to bend toward each other). However, the legs 1302 and 1303 may be pivotally coupled to each other using other mechanisms. For example, a hinge may be used to couple the leg 1302 to the leg 1303. The magnetic bead 1301 also includes a magnet 1304 attached to the free end of the leg 1302 and a magnet 1305 attached to the free end of the leg 1303. Note that a magnetic material may be substituted for one of the magnets 1304 and 1305. In some embodiments, the magnets 1304 and 1305 are embedded into the free ends of the legs 1302 and 1303, respectively. In some embodiments, the free ends of the legs 1302 and 1303 cover all of the surfaces of the magnets 1304 and 1305. In some embodiments, the free ends of the legs 1302 and 1303 cover all but one surface of the magnets 1304 and 1305, respectively, as illustrated in FIGS. 13A and 13B. In some embodiments, the magnets are selected form the group consisting of magnetic metallic elements, composite magnets, ceramic or ferrite magnets, alnico magnets, ticonal magnets, injection molded magnets, flexible magnets, rare earth magnets, and electromagnets. In some embodiments, the magnets are Neodymium magnets. In some embodiments, each magnet is a Neodymium having a grade of N42 a length of 0.27 inches, a width of 0.125 inches, and a thickness of 0.47 inches. Note that the grade and the dimensions of the Neodymium magnet depend on the size of the free ends of the legs 1302 and 1303 magnetic beads. For example, a lower grade Neodymium magnet having larger dimensions may be used for a clip that has larger legs.
In some embodiments, the magnetic bead 1301 includes two configurations. In a first configuration, the magnetic bead 1301 is open so that the free ends of the legs 1302 and 1303 are not touching each other. In a second configuration, the magnetic bead 1301 is closed so that the free ends of the legs 1302 and 1303 are touching each other. When the magnetic bead 1301 is closed, the magnets 1304 and 1305 are magnetically attached to each other and hold the magnetic bead 1301 in the closed configuration. To change the magnetic bead 1301 from the open configuration to the closed configuration, the free ends of the legs 1302 and 1303 are bent towards each other. To return the magnetic bead 1301 to the open configuration a force greater than the attractive magnetic force must be applied to magnetically detach the free ends of the legs 1302 and 1303. The free ends of the legs 1302 and 1303 must also be moved to a position so that the magnetic force between the magnets 1304 and 1305 does not pull the free ends of the legs 1302 and 1303 together again.
In some embodiments, the free ends of the legs 1302 and 1303 each have at least one substantially flat surface. In these embodiments, when free ends of the legs 1302 and 1303 are bent toward each other so that they touch, the substantially flat surfaces of the legs 1302 and 1303 are flush (i.e., there are no gaps) with each other (e.g., see FIGS. 14A to 14K).
In some embodiments, the magnetic bead 1301 includes a cavity 1306. When attaching the magnetic bead 1301 to a cord, the cord is inserted into the cavity 1306 and the magnetic bead 1301 is closed. Once closed, the magnetic bead 1301 holds the cord until the magnetic bead 1301 is opened. The cavity 1306 allows the magnetic bead 1301 to attach to the cord so that the surfaces of the free ends of the legs 1302 and 1303 are flush with each other (e.g., see FIGS. 6A to 6J). In some embodiments, the cavity 1306 is lined with a high-friction material to make the cavity 1306 more difficult to adjust when the magnetic bead 1301 is attached to a cord. In some embodiments, the cavity 1306 is lined with a low-friction material to make the cavity 1306 easier to adjust when the magnetic bead 1301 is attached to a cord.
In some embodiments, the cavity 1306 is formed of an elastic material that stretches to accommodate cords of varying sizes. The elastic material of the cavity 1306 allows the magnetic bead 1301 to attach to cords of varying sizes so that faces of the free ends of the legs 1302 and 1303 are flush with each other (e.g., see FIGS. 6A to 6J). The elastic material also provides a force against the cord so that the magnetic bead 1301 does not slip along the cord. In some embodiments, the cavity 1306 is ribbed.
Instead of using the magnets 1304 and 1305 to attach the magnetic bead 1301 to the cord, other attachment mechanisms may be used. In some embodiments, the attachment mechanism are selected form the group consisting of a snap closure, Velcro, an adhesive, a mechanical bead (e.g., a groove in the side the magnetic bead 1301 that snaps onto the cord), a latch, metal that bends and holds its shape, and the like.
FIGS. 13C and 13D illustrate cross-section views of the magnetic bead 1301, according to some embodiments. As illustrated in FIG. 13D, the magnet 1305 is shaped like a step. Specifically, the magnet 1305 includes protrusions 1310 and 1311 that are configured to hold the magnet 1305 in the material of the magnetic bead 1301. In some embodiments, the protrusions 1310 and 1311 are located on two opposing sides of the magnet 1305. The protrusions 1310 and 1311 may run the full length or a portion of the length of the side of the magnet 1305. In some embodiments, two or more protrusions may be used. For example, the magnet 1305 may include protrusions on all of the sides of the magnet 1305. Note that the magnet 1304 may also have the protrusions 1310 and 1311.
FIGS. 14A to 14k illustrate varying dimensions for magnetic beads, according to some embodiments. Each of the magnetic beads is attached to a cord for earbuds 601. Each of the magnetic beads 602, 604, 606, 608, 610, 612, 614, 616, 618, and 620 includes a cavity 603, 605, 607, 609, 611, 613, 615, 617, 619, 621, respectively. Table 1 presents exemplary dimensions for each of the magnetic beads illustrated in FIGS. 14A to 14K. In Table 1, “length” refers to the dimension of the magnetic bead (or magnet) along the cord, “width” refers to the dimension of the magnetic bead (or magnet) that is perpendicular to the cord, and “thickness” refers to the thickness of the magnetic bead (or magnet). All dimensions are listed in inches.

In some embodiments, when the magnetic beads described herein are attached to a cord, the magnetic beads can rotate about the cord so that the polarities of the magnets in the magnetic beads can be aligned so that two distinct magnetic beads can magnetically attach to each other.
In some embodiments, a magnetic sheath is used in lieu of or in addition to magnetic beads. The magnetic sheath is described in more detail in U.S. patent application Ser. No. 12/338,680, entitled “Magnetic Cord Management System,” filed Dec. 18, 2008.
Configuring the Cord Management System
FIGS. 15A to 15H illustrate the process of configuring a cord management system. These figures illustrate a cord 1515, which is an audio cord. Note that cords 1513 and 1514 are segments of the cord 1515 (e.g., see FIG. 15D), and are also audio cords.
FIG. 15A illustrates a process of attaching a magnetic bead 1520 to the cord 1513, according to some embodiments. As illustrated in FIG. 15A, the cord 1513 is inserted into a cavity (e.g., the cavity 1306 in FIG. 13A) of the magnetic bead 1520. In this case, the cord 1513 is connected to a speaker 1511 of the headphone. Similarly, the cord 1514 is connected to a speaker 1512 of the headphone. In some embodiments, the magnetic bead 1520 is attached to the cord 1513 a predetermined distance from the speaker 1511.
Once the magnetic bead 1520 is closed, the magnetic bead 1520 is attached to the cord 1513 (e.g., see FIG. 15B). In some embodiments, another magnetic bead is attached to the cord 1514 a predetermined distance from the speaker 1512, as illustrated in FIG. 15D. In some embodiments, only one of the two magnetic beads attached to the speakers 1511 and 1512 includes a magnet. In these embodiments, the other magnetic bead includes a magnetic material.
In some embodiments, a magnetic bead is opened by sliding the magnets of the magnetic bead across each other until the magnets of the magnetic bead are magnetically detached from each other. In some embodiments, a magnetic bead is opened by prying the magnets of the magnetic bead away from each other until the magnets of the magnetic bead are magnetically detached from each other.
In some embodiments, a magnetic bead 1513 is attached to the cord 1515 a predetermined distance from a connector 1516 (e.g., an audio connector). These embodiments are illustrated in FIG. 15C. In some embodiments, the predetermined distance is selected so that when the connector 1516 is inserted into the cord-attachment mechanism 1509 of the magnetic strap 1501, the magnetic bead 1523 is configured to be magnetically attached to at least one of the magnets 1502 and 1503 of the magnetic strap 1501 when the cord 1515 is wrapped around the magnetic strap 1501. The magnetic bead 1523 holds the cord 1515 on the magnetic strap 1501 to facilitate winding of the cord around the magnetic strap 1501. Thus, a user does not need to hold the cord 1515 to the magnetic strap 1501 while winding the cord 1515 around the magnetic strap 1501.
In some embodiments, a magnetic bead 1522 is attached to the cord 1513. These embodiments are illustrated in FIG. 15D. In some embodiments, the magnetic bead 1522 is attached to the cord 1513 a specified distance from the speaker 1511. In some embodiments, the specified distance is selected so that the magnetic bead 1522 can be magnetically attached to one of the magnets of the magnetic strap 1501 when the cord 1513 is wrapped around the magnetic strap 1501. In some embodiments, the specified distance is selected so that the magnetic bead 1522 can be magnetically attached to one or more of the magnetic beads 1520 and 1521 when the cord 1513 is wrapped once around an object (e.g., a mobile electronic device). For example, a user may wrap the cord 1513 once around the object and attach the magnetic bead 1522 on the cord 1513 at the location where the magnetic beads 1520 and/or 1521 intersect (or overlap) the cord 1513.
In some embodiments, the connector 1516 is inserted into the cord-attachment mechanism 1509 of the magnetic strap 1501. These embodiments are illustrated in FIGS. 15E and 15F. By inserting the connector 1516 into the cord-attachment mechanism 1509, the cord 1515 is secured to the magnetic strap 1501.
In some embodiments, a magnetic material 1524 (e.g., the magnetic material 103) is attached to an object 1530, as illustrated in FIG. 15G. Note that the magnetic material 1524 may be a magnet or magnetic material as discussed above. In these embodiments, the magnetic material 1524 is attached to the object 1530 at a predetermined location. In some embodiments, the predetermined location is selected so that when the magnetic strap 1501 is attached to the object 1530, the magnet 1502 is magnetically attached to the magnetic material 1524. These embodiments assist with the deployment of the magnetic strap 1501 and/or may be used to hold the magnetic strap 1501 to the object 1530 when the magnetic strap 1501 is in its natural configuration (e.g., the flat configuration). Note that these embodiments are also useful for electronic devices that have connectors at the bottom of the device. For these electronic devices, the magnetic strap 1501 is attached so that the cord-attachment mechanism 1509 faces downwards when the electronic device is held in an upright position (e.g., when the user is interacting with the user interface of the electronic device). Thus, when the magnetic strap 1501 is in its natural configuration (e.g., the flat configuration) and the magnetic material 1524 is not used, gravity may pull down the end of the magnetic strap 1501 that includes the magnet 1502. However, when the magnetic strap 1501 is in its natural configuration and the magnet 1502 is magnetically attached to the magnetic material 1524, the end of the magnetic strap 1501 that includes the magnet 1502 will not be pulled down by gravity. In some embodiments, the predetermined location is selected so that when the magnetic strap 1501 is attached to the object 1530, the magnet 1503 is magnetically attached to the magnetic material 1524. These embodiments may be used to hold the magnetic strap 1501 to the object 1530 when the magnetic strap 1501 is folded over into the loop configuration.
In some embodiments, the magnetic material 1524 is selected from the group consisting of a ferromagnetic material and a paramagnetic material. In some embodiments, the magnetic material 1524 is low-carbon steel. In some embodiments, the magnetic material 1524 is Vanadium carbonyl. The magnetic material 1524 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 object onto which the magnetic material is being attached and a width of the magnetic strap. In some embodiments, the magnetic material is a square having 0.5 inches sides. In some embodiments, the magnetic material is a circle having a radius of 0.5 inches. In some embodiments, the thickness of the magnetic material is 0.006 inches. Note that the magnetic material 1524 is beneficial when using the magnetic strap 1501 with an electronic device that has an audio connector port on the side or the bottom of the electronic device. In these cases, the magnetic material 1524 may be used to hold the magnetic strap 1501 to the object. Specifically, the magnetic material 1524 may be used as a magnetic attachment point for the magnet 1502 so that the magnetic strap 1502 does not dangle on the electronic device. In some embodiments, the magnetic material is galvanized or otherwise coated with a sealant. The sealant may protect against rusting and protects the end users against the sharp edges of the magnetic material.
FIG. 15J illustrates a top view and a side view of the magnetic material 1524, according to some embodiments. As illustrated, the magnetic material 1524 includes several elements. In some embodiments, the magnetic material 1524 includes a disc-shaped magnetic material 1552 (e.g., composed of the magnetic material as described herein) whose outer edge is at least partially covered and/or surrounded by a ring-shaped elastic material 1551 (e.g., an elastic polymer as described herein). The ring-shaped elastic material 1551 and/or disc-shaped magnetic material 1552 may be coated with an adhesive (or other attachment mechanism) on one surface to allow the magnetic material 1524 to be attached to the object 1530. The ring-shaped elastic material 1551 is configured to conform to the shape of the object when pressed against the object. Alternatively, or additionally, the disc-shaped material 1552 and/or the magnetic material 1524 may be attached to an intermediate material (e.g., using adhesives and the like) that includes adhesives on one or both surfaces so that the intermediate material may be attached to the object 1530 and to the disc-shaped material 1552 and the magnetic material 1524. The intermediate material may be chosen so that when the intermediate material is pressed onto the object, the intermediate material conforms to the shape of the object. For example, the intermediate material may be foam. Note that the shape of the magnetic material 1524 may be any other shape (e.g., a square, a rectangle, etc.). The elastic material that partially covers and/or surrounds the magnetic material may have a corresponding shape or may be any shape. For example, if the magnetic material 1524 has a disc shape, the elastic material may be a disc shape or may be a square shape (or any other shape).
In some embodiments, the magnetic strap 1501 is attached to the object 1530 (e.g., see FIG. 15H). The object 1530 may be a portable electronic device (e.g., a mobile phone, a music player, etc.) or any other object (e.g., a hand). In some embodiments, the magnetic material 1524 is attached to the object 1530 and the magnet 1502 of the magnetic strap 1501 is magnetically attached to the magnetic material 1501 so that the magnetic strap 1501 is attached to the object 1530. In some embodiments, the connector 1516 is connected to a port on the object 1520. In these embodiments, the magnetic strap 1501 lays flat on the surface of the object 1530. Note that the magnetic strap 1501 may also be incorporated into a case or into the object 1530, as described herein.
In some embodiments, the magnetic strap 1501 does not have a predefined “top” side and a predefined “bottom” side. In other words, either face of the magnetic strap 1501 may be used as the top (or “face up”) side on the object 1530. In some embodiments, the magnetic strap 1501 has a predefined “top” side and a predefined “bottom” side. In these embodiments, the magnetic strap 101 can only be used with the top side facing away from the object 1530.
FIG. 22 is a flowchart of a method 2200 for using a cord management system, according to some embodiments. As described above, a strap of the cord management system may be used by itself or may be used in conjunction with magnetic beads and/or a magnetic material attached to the object.
As noted above, the magnetic strap 101 may be used with or without the electronic device 210. In either case, steps 2202-2208 are performed. A cord is wrapped (2202) around the magnetic strap 101 substantially perpendicular to and/or otherwise across the magnetic strap 101 at any angle, wherein the strap includes a first set of magnets attached to a first location on the magnetic strap 101 and a second set of magnets attached to a second location on the magnetic strap 101. The magnetic strap 101 is folded (2204) so that the magnetic strap 101 forms a loop around the cord. The loop is secured (2206) by coupling the first set of magnets and the second set of magnets.
In some embodiments, when the user desires to use the cord, the cord is deployed (2208) from the magnetic strap 101 by pulling the cord away form the strap (e.g., substantially parallel to the length of the strap or in any other direction from the strap). When the cord is pulled away from the magnetic strap 101, the first set of magnets is decoupled from the second set of magnets so that the magnetic strap 101 no longer forms the loop around the cord. In embodiments where the magnetic strap 101 is used by itself to manage the cord, the cord may be deployed from the magnetic strap 101 by pulling the cord away from the magnetic strap 101 in a direction other than substantially parallel to the length of the magnetic strap 101.
FIG. 23 is a flowchart of a method 2300 for configuring a cord management system, according to some embodiments. In some embodiments, at least one magnetic material or magnet is attached (2302) to an object. For example, the magnetic material 103 may be attached to the electronic device 210.
In some embodiments, a plurality of magnetic beads and/or magnetic material is attached (2304) to a cord. In some embodiments, at least one magnetic bead of the plurality of magnetic beads is attached to the cord so that when the cord is wrapped around the strap, the at least one magnetic bead is magnetically attached to one set of magnets and/or magnetic material of the magnetic strap. In some embodiments, the cord is an audio cord of a headphone, which includes an audio connector and one or more speakers connected to the audio connector via the audio cord. In some embodiments, a first magnetic bead of the plurality of magnetic beads is attached (2320) to the audio cord at a predetermined distance from the audio connector of the headphone. In some embodiments, a second magnetic bead of the plurality of magnetic beads is attached (2322) to the audio cord at a predetermined distance from a first speaker in the one or more speakers of the headphone. In some embodiments, a third magnetic bead of the plurality of magnetic beads is attached (2324) to the audio cord at a predetermined distance from a second speaker in the one or more speakers of the headphone.
In some embodiments, the cord (and/or a connector for the cord) is attached (2306) to a cord-attachment mechanism. For example, the connector 204 of the cord 201 may be inserted into the cord-attachment mechanism of the magnetic strap 101.
In some embodiments, a first set of magnets or magnetic material of the magnetic strap 101 is attached (2308) to the magnetic material or the magnet (e.g., the magnetic material 103) attached to the object. As discussed above, instead of using a magnet attached to the object, a material onto which the magnetic strap 101 can attach to the object is used (e.g., an adhesive disc, a suction cup, etc.).
Other Embodiments
FIGS. 16-19 illustrate other embodiments of the cord management system.
FIG. 16A illustrates a magnetic strap 1601 and a cord 1602, according to some embodiments. The magnetic strap 1601 can be any of the magnetic straps discussed above (e.g., the magnetic straps 101, 601, 701, 801, or 901). As illustrated in FIG. 16A, the magnetic strap 1601 includes magnets 1605 and 1606 and the cord 1602 includes speakers 1603 and 1604. In contrast to the embodiments described above, the cord-attachment mechanism of the magnetic strap 1601 is not used to attach the magnetic strap 1601 to the cord 1602. In order to use the magnetic strap 1601 with the object, the magnetic strap 1601 is attached to the object. In some embodiments, the magnetic strap 1601 is magnetically attached to the object. In these embodiments, magnetic material (e.g., the magnetic material 103) is attached to the object (e.g., using adhesives, suction cups, Velcro, etc., as described above) so that at least one of magnets 1605 and 1606 can be magnetically attached to the magnetic material. When the magnets 1605 and/or 1606 are magnetically attached to the magnetic material, the magnetic strap is coupled to the object. In some embodiments, the magnetic strap 1601 is attached to the object using one selected from the group consisting of adhesives, suction cups, Velcro, and a van der Waals force attachment mechanism.
As described above and as illustrated in FIGS. 16A and 16B, the cord 1602 can be wrapped around the object and the magnetic strap 1601 and secured by folding the magnetic strap 1601 into the loop, as described above.
FIG. 26A illustrates an object 2601 and the cord 201 secured by the magnetic strap 101, according to some embodiments. As illustrated in FIG. 26A, the cord 201 and the magnetic strap 101 are detached from the object 2601. A magnetic material 2602 is also attached to the object 2601. As discussed above, the magnetic material 2602 may be located on the object 2601 so that when the magnetic strap 101 is attached to the object 2601, one of the magnets 104 and 105 can be magnetically attached to the magnetic material 2602. In some cases, the end user may reattach the magnetic strap 101 and/or the cord 201 to the object 2601 without deploying the cord 201 from the magnetic strap 101, as illustrated in FIG. 26B. In some cases, a user may have already wrapped the cord 201 in the magnetic strap 101 where the magnetic strap 101 is detached from the object 2601. In these cases, the user may reattach the magnetic strap to the object 2601 to hold the magnetic strap 101 and the cord 201 to the object 2601. FIG. 26C illustrates the magnetic strap 101 attached to the object 2601, according to some embodiments. As illustrated in FIG. 26C, the connector for the cord 201 is not attached to the cord-attachment mechanism of the magnetic strap 101. The magnetic strap 101 may be attached to the surface of the object 2601 using any of the attachment mechanisms discussed herein (e.g., magnets, suction cups, adhesives, etc.). For example, the magnetic material 103 may be attached to the object.
