DYNAMICALLY ADJUSTABLE BANDS FOR WEARABLE DEVICES

TECHNICAL FIELD

This application is directed to bands for wearable devices, and more particularly, to dynamically adjustable bands that are used to secure wearable devices to users.

BACKGROUND

Wearable devices often include a band used to secure the wearable device to a user. In order to adjust the band to a desired length (corresponding to a diameter for a user's wrist), bands require a user-initiated adjustment. For example, some bands include two separate band portions, with one portion carrying a clasp that can enter one of a number of openings in the other portion of the band, with the different openings accommodating different wrist sizes. In another example, one portion of the band includes an external magnet that can magnetically couple to a magnetically attractable feature(s) on the other portion of the band.

DETAILED DESCRIPTION

The detailed description set forth below is intended as a description of various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced. The appended drawings are incorporated herein and constitute a part of the detailed description. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. However, it will be clear and apparent to those skilled in the art that the subject technology is not limited to the specific details set forth herein and may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the subject technology.

This disclosure is directed to bands for wearable devices. In particular, the bands described herein are designed to dynamically adjust (e.g., expand and contract) without a user having to manually adjust the band to change the size of the band. Put another way, the diameter of the band may increase or decrease without a user modifying clasps or other external mechanical features. Also, the band is designed to adjust to different users in a manner that provides an appearance of the same force applied to each user, regardless of users with different appendage sizes. The term “appendage” as used in this detailed description and in the claims refers to a user's extremity including, but not limited to, a wrist, a forearm, a bicep, a leg, an ankle, and a shin. Also, while wrist is used throughout this detailed description, it should be noted that “wrist” may be substituted with the aforementioned forms of an appendage.

In some exemplary embodiments, the band includes an exterior structure that encloses an internal structure (or structures). In an initial steady state, the exterior structure applies a force that holds the interior structure(s) in tension. As a result, an additional, external force applied to the band that causes additional tension to the interior structure(s) causes a relatively small amount of change in tension to the interior structure(s). For example, when a user places a wrist through a loop formed by the band, the force provided by the user's wrist results in little change in tension to the interior structure(s) of the band. In another example, when a different user with a larger wrist places the wrist through the loop, the additional force provided by the user's larger wrist may cause the band to expand and increase the diameter of the loop. However, little change in tension to the interior structure(s) occurs. Accordingly, each user may experience the appearance of the same, or substantially similar, force provided by the band.

In another example, some users may experience swelling of a wrist due to physical activity, which increases the force provided to the band. The interior structure(s) may nonetheless undergo little change in tension. In this manner, while the loop formed by the band may increase in diameter to accommodate the swelling wrist, the user may experience the appearance of the same, or substantially similar, force provided by the band.

Based on the interior structure(s), the band may provide a constant force to users despite the users having different wrist sizes. The force may be constant, or appear substantially constant to within ±0.5 Newtons (N) of a given force, through a range of displacement. The range of displacement may include a predetermined or expected range of loop diameters for a given band. Further, bands, including their structural components, may be tuned to provide a force within a desired range of forces, such as a range of approximately 0.5 to 1.5 N.

The interior structure(s) held in tension may include metal structures, including steel structures. Further, some metal structures described herein may be bent or curved in a manner corresponding to the curvature of a loop of a band. These interior structure(s) may be covered by an exterior structure(s) such that the exterior structure(s) pulls the interior structure(s) in tension. Alternatively, the interior structure(s) may include a structure with elastic features, thus allowing the interior structure(s) to expand contract.

Additionally, after the additional force provided by, for example, a user's wrist is removed from the band, the band may return to its initial size and shape. Accordingly, the band is a self-adjusting band that does not require specific user interaction to change the size of the band. Beneficially, the band can dynamically adjust to different users, while providing the appearance to different users of the same force to the user's wrist.

These and other embodiments are discussed below with reference to FIGS. 1-16. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these Figures is for explanatory purposes only and should not be construed as limiting.

According to some embodiments, for example as shown in FIG. 1, an electronic device 100 is shown in the form of a wearable device, or smartwatch, capable of being worn by a user on a wrist of the user. Electronic device 100 includes a device housing 102 that includes an internal chamber, or internal volume, that stores operational components, such as processors (including a central processing unit and a graphics processing unit), a memory circuit, electronic sensors (e.g., heart rate sensor, blood-oxygen level sensor), and a battery, as non-limiting examples. Device housing 102 may include a metal housing or non-metal housing.

To secure to a user, electronic device 100 may include a band 104 that wraps around a wrist of a user. Band 104 may include one or more of a variety of materials, such as silicone, woven fabric, elastic (or materials with elastically stretchable characteristics), or multiple metal links, as non-limiting examples. As shown in FIG. 1, band 104 can secure with device housing 102 at multiple locations. For example, device housing 102 includes a receptacle 106a and a receptacle 106b. As shown in in FIG. 1, opposing ends of band 104 can secure within receptacles 106a and 106b of device housing 102. While band 104 is shown as being connected to device housing 102, band 104 can be disconnected with device housing 102 at receptacles 106a and 106b, and replaced with one or more bands (not shown in FIG. 1). Accordingly, band 104 can be detachably secured with device housing 102.

Electronic device 100 further includes a display 108 designed to present visual information in the form of textual information, still images, or motion images (e.g., video). Display 108 may include a light-emitting diode (LED) display or an organic light-emitting diode (OLED) display, as non-limiting examples. Additionally, display 108 may include a capacitive touch input display, thus allowing display 108 to take the form of a touchscreen to receive an input from a user.

Additionally, electronic device 100 may include input mechanisms designed to provide an input to a processor of electronic device 100, with the input causing the processor to provide a command to alter and update the visual information provided by display 108. For example, electronic device 100 includes an input mechanism 110. In some embodiments, input mechanism 110 includes a button that, when depressed, actuates a switch to generate an input. Alternatively, in some embodiments, input mechanism 110 includes a dial that, when rotated, generates an input, with the input varying based upon clockwise rotation or counterclockwise rotation of input mechanism 110. Although not shown, one or more input mechanisms may be included, each of which may take a form of input mechanism 110 as described herein.

Referring again to band 104, when a respective end of band 104 is secured within receptacles 106a and 106b, band 104 forms a continuous loop with diameter D₁. Traditional bands for wearable devices include multiple, separable components that can be moved relative to each other and coupled together by a clasp to change the diameter of the loop. However, as shown in FIG. 1, band 104 is a continuous, single-piece band. As will be described below, band 104 can dynamically change in diameter.

Referring to FIG. 2, band 104 is elongated and the loop formed by band 104 includes a diameter D₂that is greater than D₁(shown in FIG. 1). The length of band 104 may increase based upon external forces acting on band 104. For example, users with different wrist sizes (i.e., wrist diameters) can wear electronic device 100, causing band 104 to elongate such that the loop formed by band 104 increases to D₂. Alternatively, when a user's wrist increases in size, the increased size can cause the loop of band 104 to increase to D₂. Still further, the user can cause the loop of band 104 to increase by moving electronic device 100 to a different location on the user (e.g., from wrist to bicep). When the external force acting on band 104 is removed, band 104 can return to its original size and the loop formed by band 104 can return to its original diameter, i.e., diameter D₁. While D₂represents a single diameter change from D₁, it should be noted that several additional diameters different from D₂, and greater than D₁, are possible.

FIGS. 3 and 4 show various structures for band 104 (shown in FIGS. 1 and 2). Referring to FIG. 3, a structural member 120 for band 104 is shown. While structural member 120 includes a rectangular shape, other shapes are possible. As shown in FIG. 3, structural member 120 includes a dimension 122, representing a one-dimensional length of structural member 120. Also, dimension 122 represents a steady-state length of structural member 120. Put another way, dimension 122 of structural member 120 represents a length when no other external forces are acting upon structural member 120, with the exception of gravitational forces.

In some embodiments, structural member 120 includes one or more textile materials. For example, structural member 120 may include one or more fabrics, or one or more yarns, as non-limiting examples. Alternatively, or additionally, structural member 120 may further include elastic (or an elastically stretchable material), polymers, leather, metal, or some combination thereof. Moreover, the selected material(s) may be knitted or woven together to form structural member 120. Generally, structural member 120 may include any material(s) with elastically compressible properties, thus allowing structural member 120 to change (e.g., decrease) its length to a length less than dimension 122 when a force(s) is/are acting upon structural member 120, while also allowing structural member 120 to return to its original, uncompressed length (i.e., dimension 122) when the force(s) is/are removed.

As shown in FIG. 3, structural member 120 includes an internal chamber 124 (shown as a dotted line) designed to receive and enclose another structural member(s) of band 104. Internal chamber 124 represents a three-dimensional void or space within structural member 120. In this regard, internal chamber 124 may be referred to as a sleeve or a pocket.

Also, structural member 120 may include an end 126a and end 126b, representing opposing ends of structural member 120. Ends 126a and 126b may be referred to as a first end and a second end, respectively. However, “first” and “second” may be interchanged.

Referring to FIG. 4, structural members 130a and 130b for band 104 are shown. While structural members 130a and 130b each includes a rectangular shape, other shapes are possible. For example, structural members 130a and 130b may each take the form of a cylindrical shape. When band 104 is assembled, structural members 130a and 130b may be disposed in internal chamber 124 of structural member 120 (shown in FIG. 3).

As shown in FIG. 4, structural members 130a and 130b include a dimension 132a and a dimension 132b, respectively. Dimensions 132a and 132b represent a one-dimensional length of structural members 130a and 130b, respectively. Also, dimensions 132a and 132b represent a steady-state length of structural members 130a and 130b, respectively. Put another way, dimension 132a and dimension 132a represent a length of structural member 130a and structural member 130a, respectively, when no other external forces are acting upon structural members 130a and 130b, with the exception of gravitational forces.

In some embodiments, structural members 130a and 130b include a metal, such as steel. However, in some embodiments, structural members 130a and 130b each includes a material(s) with elastically stretchable properties, thus allowing structural members 130a and 130b to change (e.g., increase) their length to a length greater than that of dimension 132a and dimension 132b, respectively, when acted upon by an external force(s). When the external force(s) is/are removed, structural members 130a and 130b subsequently return to their original length (i.e., dimensions 132a and 132b).

Referring to FIG. 5, band 104 is assembled with structural members 130a and 130b positioned within internal chamber 124 of structural member 120. Accordingly, structural member 120 may be referred to as an outer structural member or exterior structural member, and structural members 130a and 130b may be referred to as inner structural members or interior structural members. Further, when structural member 120 is formed from a fabric-based material, structural member 120 may be referred to as a fabric cover. While structural members 120, 130a and 130b are shown as flat or planar, the structures may be bent or curved to secure with an electronic device (e.g., electronic device 100 shown in FIGS. 1 and 2). Structural member 130a and 130b each include an end region, or simply an end, that is fixed in an end of structural member 120. As shown, structural member 130a includes an end that is fixed with end 126a and structural member 130b includes an end that is fixed with end 126b. Also, ends 126a and 126b of structural member 120 may take the form of ends for band 104 when band 104 is assembled.

As shown in FIG. 5, structural members 130a and 130b may overlap based on their respective dimensions. Additionally, when disposed in structural member 120, structural members 130a and 130b may be under tension based on a pulling force applied by structural member 120. This may occur when band 104 is secured with an electronic device. Additionally, while structural members 130a and 130b are under tension by structural member 120, structural members 130a and 130b may apply a compression force to structural member 120, causing at least some reduction in a dimension of structural member 120. For example, as shown in FIG. 5, structural member 120 undergoes compression and reduces to a dimension 142 that is less than dimension 122 (shown in FIG. 3). The compression of structural member 120 may bias ends 126a and 126b to toward a central portion 143 located between ends 126a and 126b.

Referring to FIG. 6, band 104 is assembled with device housing 102. For example, ends 126a and 126b are secured within receptacles 106a and 106b, respectively, of device housing 102. Based on an end of structural members 130a and 130b being positioned in ends 126a and 126b, respectively, an end of structural members 130a and 130b is also secured within receptacles 106a and 106b, respectively.

As shown in FIG. 6, structural members 130a and 130b are curved structural members. Structural member 120 applies a force that places structural members 130a and 130b in tension. Structural members 130a and 130b may each provide a counterforce or counterbalance, which is a function of a spring constant of structural members 130a and 130b. Accordingly, each of structural members 130a and 130b may be referred to as a spring element. Simultaneously, structural members 130a and 130b combine to apply a force that compresses structural member 120. Without other forces acting on structural members 120, 130a, and 130b, band 104 forms a loop with diameter D₁.

At a steady state condition, band 104 forms a loop with diameter D₁. In this regard, diameter D₁is an expected diameter of the loop of band 104 when structural member 120 provides a force to structural members 130a and 130b, and structural members 130a and 130b provide a force to structural member 120, and no other external force(s) is/are applied with the exception of gravitational forces. When an external force is applied to band 104, band 104 may lengthen, causing the loop to lengthen to a diameter greater than diameter D₁. However, due in part to structural member 120 placing structural members 130a and 130b in tension, additional tension provided by an external force (i.e., a force other than the tension provided by structural member 120) to structural members 130a and 130b results in a relatively small change in tension to structural members 130a and 130b. For example, different users having different wrist sizes may wear electronic device 100 and apply different degrees of tension to structural members 130a and 130b. In another example, a user may wish to move electronic device 100, including band 104, from the wrist do a different extremity (e.g., forearm, bicep, or leg) having a larger diameter than that of the wrist. However, each of the users may experience a similar feel (i.e., similar force) provided by band 104 when wearing electronic device 100, due in part to the relatively small change in tension to structural members 130a and 130b, regardless of the different applied tension from different users. In another example, a user wearing electronic device 100 may undergo physical activity, causing the user's wrist to swell and increase in diameter. While this may cause band 104 to expand to a diameter greater than diameter D₁, the relatively small change in tension to structural members 130a and 130b may cause the user to feel the same force applied by band 104 to the user. Accordingly, structural members 130a and 130b, when placed in tension by structural member 120, provide a counterforce that appears constant, or approximately constant, to a user (or users) for a given range of displacement of band 104. An example of a given range of displacement may include a predetermined range of wrist sizes/diameters for a variety of users. It should be noted that when the external force providing tension is removed from band 104 (particularly, to structural members 130a and 130b), the loop formed by band 104 may return to its original diameter, i.e., diameter D₁, thus allowing band 104 to dynamically change back to its steady state condition.

Also, as shown in FIG. 6, structural members 130a and 130b overlap each other. When additional tension is applied to structural members 130a and 130b, structural members 130a and 130b may remain overlapped. However, in some embodiments, additional tension by an external force may cause structural members 130a and 130b to transition from an overlapping configuration shown in FIG. 6 to a non-overlapping configuration, with a transition back to the overlapping configuration when the additional tension is removed.

FIGS. 7-16 show alternate embodiments of bands for electronic devices. The bands shown and described in FIGS. 7-16 may include at least some features previously described for bands.

Referring to FIG. 7, an electronic device 200 includes a band 204 with a structural member 220 and structural members 230a and 230b positioned within structural member 220, with structural members 230a and 230b in a non-overlapping configuration. Further, band 204 is in a steady-state position with no additional forces acting on band 204 or its components, and structural members 230a and 230b do not overlap each other. Based on the configuration shown in FIG. 7, structural member 220 applies a force that places structural members 230a and 230b in tension, and structural members 230a and 230b provide a force that may provide at least some compression to structural member 220.

Referring to FIG. 8, an electronic device 300 includes a band 304 with a structural member 320 and structural members 330a and 330b positioned within structural member 320, with structural members 330a and 330b having stop mechanisms. Based on the configuration shown in FIG. 8, structural member 320 applies a force that places structural members 330a and 330b in tension, and structural members 330a and 330b provide a force that may provide at least some compression to structural member 320. Further, band 304 is in a steady-state position with no additional forces acting on band 304 or its components.

As shown in the enlarged view, structural members 330a and 330b overlap each other and include a stop mechanism 338a and a stop mechanism 338b, respectively. In this regard, when an external force is applied to band 304 that would cause band 304 to otherwise displace beyond a predetermine range, structural members 330a and 330b may move apart from each other such that stop mechanisms 338a and 338b engage each other, thus preventing further displacement of band 304.

FIGS. 9 and 10 show various structures for one or more bands described herein. Referring to FIG. 9, a structural member 420 for a band is shown. Structural member 420 includes a dimension 422, representing a one-dimensional length of structural member 420. Also, dimension 422 represents a steady-state length of structural member 420. Put another way, dimension 422 of structural member 420 represents a length when no other external forces are acting upon structural member 420, with the exception of gravitational forces.

In some embodiments, structural member 420 includes one or more textile materials. For example, structural member 420 may include one or more fabrics, or one or more yarns, as non-limiting examples. Moreover, the selected material(s) may be knitted or woven together to form structural member 420. Generally, structural member 420 may include any material(s) with elastically compressible properties, thus allowing structural member 420 to change (e.g., decrease) its length to a length less than that of dimension 422 when an external force(s) is/are acting upon structural member 420, while also allowing structural member 420 to return to its original length (i.e., dimension 422) when the external force(s) is/are removed. While structural member 420 includes a rectangular shape, other shapes are possible.

As shown in FIG. 9, structural member 420 may include an internal chamber 424 designed to receive and enclose another structural member(s) of a band. Also, structural member 420 may include an end 426a and end 426b, representing opposing ends of structural member 420. When structural member 420 is assembled to form a band, ends 426a and 426b may be used as ends of the band.

Also, structural member 420 includes several discrete elements. For example, structural member 420 includes an element 428a, an element 428b, and an element 428c. Elements 428a, 428b, and 428c (representative of several additional elements of structural member 420) may include fabric elements, yarn elements, or the like.

Referring to FIG. 10, a structural member 430 for a band is shown. Structural member 430 may include one or more materials. While structural member 430 includes a rectangular shape, other shapes are possible. For example, structural member 430 may take the form of a cylindrical shape. When a band is assembled, structural member 430 may be disposed in internal chamber 424 of structural member 420 (shown in FIG. 9).

As shown in FIG. 10, structural member 430 includes a dimension 432, representing a one-dimensional length of structural member 430. Also, dimension 432 represents a steady-state length of structural member 430. Put another way, dimension 432 of structural member 430 represents a length when no other external forces are acting upon structural member 430, with the exception of gravitational forces.

In some embodiments, structural member 430 includes an elastic material. Generally, structural member 430 may include any material(s) with elastically stretchable properties, thus allowing structural member 430 to change (e.g., increase) its length to a length greater than that of dimension 432 when an external force(s) is/are acting upon structural member 430, while also allowing structural member 430 to return to its original length (i.e., dimension 432) when the external force(s) is/are removed.

Referring to FIG. 11, a band 404 formed from structural members 420 and 430 is shown. When band 404 is assembled, structural member 430 can be positioned in internal chamber 424 of structural member 420, such that structural member 430 is enclosed by and hidden within structural member 420. In this manner, structural member 430 may be referred to as an inner structural member or interior structural member, and structural member 420 may be referred to as an outer structural member or exterior structural member. Also, structural member 420 and structural member 430 may be referred to as a first structural member and a second structural member, respectively. However, “first” and “second” may be interchanged.

When band 404 is assembled, ends 426a and 426b may also be used as opposing ends for band 404. Ends 426a and 426b can be detachably coupled to receptacles of a device housing of an electronic device, thus allowing band 404 to detachably couple from the device housing. Although not explicitly shown, ends 426a and 426b can be modified to include a shape corresponding to that of the receptacles of the device housing.

Also, an assembly process of band 404 may include securing opposing ends of structural member 430 with ends 426a and 426b, respectively, of structural member 420, as shown in FIG. 11. By securing opposing ends of structural member 430 to ends 426a and 426b, structural members 420 and 430 can act on each other to change their respective dimensions. This may occur, for example, when band 404 is secured to a device housing. For example, as a result of a force applied by structural member 420, structural member 430 increases from dimension 422 (shown in FIG. 10) to a dimension 442. Conversely, as a result of a force applied by structural member 430, structural member 420 compresses and decreases from dimension 432 (shown in FIG. 9) to a dimension 444. The compression of structural member 420 may bias ends 426a and 426b to toward a central portion 443 located between ends 426a and 426b. Accordingly, structural member 420 provides a force that elongates structural member 430 and places structural member 430 in tension, while simultaneously, structural member 430 provides a force that compresses structural member 420, thus reducing the length of structural member 420.

Regarding structural member 420, FIG. 11 shows adjacent elements of structural member 420 engaging each other based on the compression force provided by structural member 430. For example, elements 428a and 428b engage each other, and elements 428b and 428c engage each other. Based upon the force provided by structural member 430 and the material makeup of elements 428a, 428b, and 428c, the elements 428a, 428b, and 428c may individually compress and reduce in size, and the reduce of structural member 420 may be attributed to the individual compressions of elements 428a, 428b, and 428c. Additionally, the engagement by the adjacent elements of structural member 420 provides at least some of the force that maintains tension (e.g., the pulling force) that expands structural member 430.

Referring to FIG. 12, an electronic device 400 with band 404 is shown. Electronic device 400 may include any feature(s) previously described for an electronic device, including a device housing 402 and receptacles 406a and 406b. Band 404 is secured with device housing 402 by way of ends 426a and 426b being positioned in receptacles 406a and 406b, respectively, of device housing 402.

At a steady state condition, band 404 forms a loop with diameter D₁. In this regard, diameter D₁is an expected diameter of the loop of band 404 when structural members 420 and 430 apply their respective forces on each other and no other external force(s) is/are applied, with the exception of gravitational forces. When an external force is applied to band 404, however, band 404 may lengthen, causing the loop to lengthen to a diameter greater than diameter D₁. Due in part to structural member 420 placing structural member 430 in tension, additional tension provided by the external force to structural member 430 results in a relatively small change in tension to structural member 430. The additional force that provides tension may be applied by different users with different wrist diameters, or a user with a wrist that changes in diameter during, for example, physical activity. In either event, users may experience a similar feel (i.e., similar force) provided by band 404, due in part to the relatively small change in tension to structural member 430, regardless of varying applied tension from wrists of different sizes. Accordingly, structural member 430, when placed in tension by structural member 420, provides a force that appears constant, or approximately constant, to a user (or users) for a given range of displacement of band 404. It should be noted than when the external force providing tension is removed from band 404 (particularly, to structural member 430), the loop formed by band 404 may return to its original diameter, i.e., diameter D₁.

FIGS. 13 and 14 show an electronic device 500 with a band 504 having alternate structural elements. Referring to FIG. 13, electronic device 500 includes a band 504 with a structural element 520 and structural members 530a and 530b disposed within structural element 520. As shown in the enlarged view, structural members 530a and 530b include several magnetic elements. For example, structural member 530a includes a magnetic element 546a, a magnetic element 546b, a magnetic element 546c, and a magnetic element 546d, while structural member 530b includes a magnetic element 548a, a magnetic element 548b, magnetic element 548b, and a magnetic element 548d. As shown in FIG. 13, magnetic elements 546a, 546b, 546c, and 546d of structural member 530a are magnetically coupled to magnetic elements 548a, 548b, 548c, and 548d, respectively, of structural member 530b. The aforementioned magnetic couplings may apply tension to structural members 530a and 530b, in addition to the tension applied by structural element 520. Alternatively, the aforementioned magnetic couplings may apply virtually all tension to structural members 530a and 530b, while little or no tension is applied by structural element 520.

At a steady state condition, band 504 forms a loop with diameter D₁. However, an external force provided to band 504 may cause band 504 to lengthen such that the looped formed by band 504 increases. Referring to FIG. 14, band 504 forms a loop with a diameter D₂that is greater than diameter D₁(shown in FIG. 13). Based on the increased diameter, at least one of structural members 530a and 530b may undergo relative movement (e.g., movement away from each other), causing new magnetic couplings between the respective magnetic elements of structural members 530a and 530b. For example, magnetic elements 546c and 546d of structural member 530a are magnetically coupled to magnetic elements 548a and 548b, respectively, of structural member 530b. The remaining magnetic elements are not magnetically coupled to another magnetic element. The relative movement of structural element 530a and/or structural element 530b may be provided by a user of electronic device 500. Further, any additional tension provided by an external force (e.g., provided by a user) to structural members 530a and 530b results in a relatively small change in tension to structural members 530a and 530b. Additionally, the movement of structural member 530a and 530b, and subsequent retention by the magnetic couplings, may assist structural members 530a and 530b in providing a counterforce to maintain an appearance of a constant force to users. It should be noted than when the external force providing tension is removed from band 504 (particularly, to structural members 530a and 530b), the loop formed by band 504 may return to its original diameter, i.e., diameter D₁, and the original magnetic couplings shown in FIG. 13 may again be formed.

FIGS. 15 and 16 show an electronic device 600 with a band 604 having alternate structural elements. Referring to FIG. 15, electronic device 600 includes a band 604 with a structural element 620 and structural members 630a and 630b disposed within structural element 620. As shown in the enlarged view, structural members 630a and 630b include structures coupled together. For example, structural member 630a includes a detent 652a, detent 652b, a detent 652c, and a detent 652d, while structural member 630b includes a receptacle 654a, a receptacle 654b, a receptacle 654c, and a receptacle 654d. Further, detents 652a 652b, 652c, and 652d of structural member 630a are positioned in receptacles 654a, 654b, 654c, and 654d, respectively, of structural member 630b. The aforementioned couplings may apply tension to structural members 630a and 630b, in addition to the tension applied by structural element 620. Alternatively, the aforementioned couplings may apply virtually all tension to structural members 630a and 630b, while little or no tension is applied by structural element 620.

At a steady state condition, band 604 forms a loop with diameter D₁. However, an external force provided to band 604 may cause band 604 to lengthen such that the looped formed by band 604 increases. Referring to FIG. 16, band 604 forms a loop with a diameter D₂that is greater than diameter D₁(shown in FIG. 15). Based on the increased diameter, at least one of structural members 630a and 630b may undergo relative movement (e.g., movement away from each other), causing new couplings between their respective detents and receptacles. For example, detents 652c and 652d of structural member 630a are positioned in receptacles 654a and 654b, respectively, of structural member 630b. Detents 652a and 652b are no longer positioned in a receptacle. The relative movement of structural element 630a and/or structural element 630b may be provided by a user of electronic device 600. Further, any additional tension provided by an external force (e.g., provided by a user) to structural members 630a and 630b results in a relatively small change in tension to structural members 630a and 630b. Additionally, the movement of structural member 630a and 630b, and subsequent retention by the detent/receptacle couplings, may assist structural members 630a and 630b in providing a counterforce to maintain an appearance of a constant force to users. It should be noted than when the external force providing tension is removed from band 604 (particularly, to structural members 630a and 630b), the loop formed by band 604 may return to its original diameter, i.e., diameter D₁, and the original couplings shown in FIG. 15 may again be formed.
