The described embodiments relate generally to wearable bands. More particularly, the present embodiments relate to wearable bands that include incremental adjustment mechanisms.
Users frequently encounter a variety of different electronic devices in the modern world. Such electronic devices include computers, media players, entertainment systems, displays, communication systems, and so on. Many electronic devices, such as laptop computers, tablet computers, and smart phones, are portable. Some of these portable electronic devices may be configured to be worn by a user. In some cases, a wearable electronic device includes one or more bands, straps, or other attachment devices that may be used to attach the wearable electronic device to a body part of a user. For example, a wrist worn wearable electronic device may include a band that can be used to secure the wearable electronic device to a user's wrist.
A band used to secure the wearable electronic device may not attach the electronic device to the body part as tightly as desired or needed. For example, an electronic device may be able to shift on or slide around the body part while attached to the body part. Additionally or alternatively, the band may be sufficiently loose on the body part such that one or more components (e.g., sensors) in the electronic device may not be able to operate, or may not function as well, due to the loose fit of the band on the body part.
In one aspect, a wearable band is configured to couple with an electronic device, such as a health assistant or a watch. The wearable band includes a first band segment, a second band segment, and an attachment mechanism configured to couple the first and second band segments together. The second band segment can include a first band sub-segment and a second band sub-segment. An incremental adjustment mechanism may be operably connected to at least one of the first band sub-segment and the second band sub-segment. When the wearable band is secured to a body part of a user, the attachment mechanism produces a first band tightness around the body part. The incremental adjustment mechanism is configured to move one band sub-segment with respect to other band sub-segment to incrementally adjust the first tightness of the band to a second tightness.
In another aspect, a wearable band includes a folding clasp coupled to a first band segment and to a second band segment. The folding clasp is configured to open and close when a user secures the wearable band to a body part. One example of a folding clasp is a single deployant clasp. The folding clasp produces a first band tightness for the band around the body part when the folding clasp is closed. An incremental adjustment mechanism is included in the folding clasp. The incremental adjustment mechanism comprises a button configured to open the folding clasp when pushed and to adjust a spacing between the first and the second band segments to incrementally adjust the first band tightness to a second band tightness.
In yet another aspect, a wearable band can include an expandable clasp, such as a butterfly clasp. The expandable clasp includes two top segments coupled to two bottom segments. A respective top segment is connected to a first band segment and a second band segment. The expandable clasp is configured to open and close when a user secures the wearable band to a body part. The two top segments fold down onto two bottom segments when the clasp is closed. The expandable clasp produces a first band tightness for the band around the body part when the folding clasp is closed. An incremental adjustment mechanism is coupled to the two bottom segments and configured to move with respect to each other to incrementally adjust the first band tightness to a second band tightness.
The disclosure will be readily understood by the following detailed description in conjunction with the accompanying drawings, wherein like reference numerals designate like structural elements, and in which:
Reference will now be made in detail to representative embodiments illustrated in the accompanying drawings. It should be understood that the following descriptions are not intended to limit the embodiments to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined by the appended claims.
The following disclosure relates to a wearable band that attaches to a body part of a user using an attachment mechanism. The wearable band and/or the attachment mechanism can include an incremental adjustment mechanism. The incremental adjustment system permits a user to have much finer control over the fit of a band than is provided by a typical band. This can lead to increased comfort when the user is wearing the band. This increased comfort can result in a user wearing the electronic device for longer periods of time, which may bring attendant benefits dependent on the functions of the device. For example, a user may be able to operate one or more health monitoring applications or functions for a longer period of time.
The incremental adjustment mechanism is configured to allow the user to adjust the fit or tightness of the wearable band more finely than the attachment mechanism. The attachment mechanism can produce an initial fit or tightness and the incremental adjustment mechanism can adjust the initial tightness. In other words, a user can use the attachment mechanism to select a first band tightness or a second band tightness. The incremental adjustment mechanism is configured to adjust the chosen first or second band tightness by a fraction of the difference between the first and second band tightnesses.
In some embodiments, the incremental adjustment of a wearable band can be done before a user secures the band to a body part. In other embodiments, the incremental adjustment of the wearable band may be done while a user is wearing the band on the body part. This “on-the-fly” incremental adjustment allows a user to change the tightness of a band at various times during a day based on comfort and/or activity. For example, a user may want a slightly tighter fit when exercising so a health sensor (e.g., heart rate monitor) can operate more effectively. However, at other times of the day the user may want a looser fit. Several techniques are disclosed for performing incremental adjustments.
In a first example embodiment, a wearable band includes two band segments that are configured to couple together with the attachment mechanism. One of the band segments includes two band sub-segments that are operably coupled together with the incremental attachment mechanism. The incremental attachment mechanism is configured to move one band sub-segment with respect to the other band sub-segment, or to move both band sub-segments to incrementally adjust the tightness of the band. In one non-limiting example, the two band sub-segments each include a toothed edge. The toothed edges are positioned opposite one another. A rotatable gear is positioned between the two toothed edges. A dial is attached to the gear and a user turns the dial to incrementally adjust the tightness of the band when the wearable band is attached to the body part of the user. As one example, the user can rotate the dial in a clockwise direction to loosen the tightness of the wearable band, or the user can rotate the dial in a counter-clockwise direction to increase the tightness of the wearable band around the body part.
In a second example embodiment, the first band segment can include a post that couples with an opening in the second band segment. The post is movable between at least two positions on the first band segment. For example, the post may rotate from a first position to a second position to incrementally adjust the tightness of the band. Alternatively, the post may slide or shift from the first position to the second position. In one embodiment, the post may be positioned at only two positions. In another embodiment, the post can be positioned at three or more different positions (e.g., post can be positioned at 0 degrees, 90 degrees, and 180 degrees along a half circle).
In some embodiments, a user can select a post from multiple posts connected to the first band segment to couple with an opening in the second band segment. As one example, the posts may rotate from a first position to a second position to position the selected post in a location to couple with the opening. For example, one post may be positioned to couple with the opening at the first position and another post can be positioned to couple with the opening at the second position. The multiple posts can have different dimensions (e.g., round posts with different diameters). A user may incrementally adjust the tightness of the band by selecting a post having a particular diameter and positioning that post to couple with an opening in the second segment of the wearable band.
In other embodiments, the incremental adjustment is done prior to a user attaching the wearable band to a body part. In one example embodiment, a continuous wearable band can include a foldable and unfoldable attachment mechanism. One example of a foldable and unfoldable attachment mechanism is a single deployant clasp. With a single deployant clasp, a first wing of the band folds down onto a second wing of the band and couples to the second wing. To uncouple the first and second wings, a user can pull up or press one or more buttons to release the first wing from the second wing.
Alternatively, another example of a foldable and unfoldable attachment mechanism is an expandable clasp such as a butterfly clasp. With a butterfly clasp, two top segments of the band unfold from (open) and fold down onto (closed) two bottom segments. An incremental adjustment mechanism can be included in the attachment mechanism or in the continuous band. As one example, when the butterfly clasp is open, at least one bottom segment moves with respect to the other segment to incrementally adjust the tightness of the band. A plate can attached to both bottom segments with fasteners (e.g., screws) to secure the two bottom segments together when the band is at a desired length. As one example, the bottom segments can be coupled together with a tongue and groove joint that allows one or both bottom segments to slide closer together or farther apart.
These and other embodiments are discussed below with reference to
The wearable electronic device 100 can include a display 102 at least partially surrounded by an enclosure 104. In some embodiments, the display 102 may incorporate an input device configured to receive touch input, force input, temperature input, and the like. The display 102 can be implemented with any suitable display, including, but not limited to, a multi-touch sensing touchscreen device that uses liquid crystal display (LCD) technology, light emitting diode (LED) technology, organic light-emitting display (OLED) technology, or organic electro luminescence (OEL) technology. The display 102 can have any given size and be located substantially anywhere on the electronic device 100.
The enclosure 104 can be formed of one or more components operably connected together, such as a front piece and a back piece. Alternatively, the enclosure 104 can be formed of a single piece operably connected to the display 102. The enclosure 104 can be formed of any suitable material, including, but not limited to, plastic and metal. In the illustrated embodiment, the enclosure 104 is formed into a substantially rectangular shape, although this configuration is not required.
The enclosure 104 can form an outer surface or partial outer surface for the internal components of the electronic device 100. For example, the electronic device 100 can include internal components such as a processing device operably connected to a memory, one or more sensors, one or more communication interfaces, output devices such as displays and speakers, one or more input devices, a power supply (e.g., a battery), and a health monitoring system. The communication interface(s) can provide electronic communications between the communications device and any external communication network, device or platform, such as but not limited to wireless interfaces, Bluetooth interfaces, USB interfaces, Wi-Fi interfaces, TCP/IP interfaces, network communications interfaces, or any conventional communication interfaces.
The sensor(s) may be configured to sense substantially any type of characteristic, such as but not limited to, images, pressure, light, touch, force, temperature, position, motion, and so on. For example, the sensor(s) may be an image sensor, a temperature sensor, a light or optical sensor, an atmospheric pressure sensor, a proximity sensor, a force sensor, a humidity sensor, a magnet, a gyroscope, an accelerometer, and so on.
The health monitoring system can be configured to detect, measure, or determine any suitable health parameter of a user. For example, a health monitoring system may determine a heart rate or pulse of the user, the blood pressure, and/or an amount of calories expended based on an activity. The health monitoring system, in conjunction with a communication interface, may transmit or receive health, fitness, and/or wellness data or information to or from a website or another electronic device, such as a smart telephone or tablet computing device.
The electronic device 100 is attached to a band 106. In some embodiments, the electronic device 100 is permanently attached to the band. In other embodiments, the electronic device 100 can be detachable from the band 106. As one example, the ends of the band 106 proximate to the electronic device 100 can slide in and out of grooves formed in the ends of the electronic device 100.
In the illustrated embodiment, the band includes two band segments 108, 110 that couple together when a user attaches the band to a body part (e.g., a wrist). An attachment mechanism 112, 114 at the distal ends of the band segments 108, 110, respectively, are configured to couple to each other. Any suitable type of attachment mechanism(s) can be used. For example, in one embodiment the attachment mechanism 112 is a post and the attachment mechanism 114 is one or more openings that receive the post. In another embodiment, the attachment mechanism 114 can be an opening that receives the distal end of the band segment 108. Once the distal end is through the opening, the distal end of the band segment 108 can fold over and secure to another section of the band segment 108. For example, both the distal and other section of the band segment 108 may include magnets that couple together when the band segment 108 is folded onto itself.
In some embodiments, the band 106 includes only one attachment mechanism. As one example, the attachment mechanism 114 can be an opening that receives the distal end of the band segment 108 and positions the distal end of the band segment 108 between the body part and the band segment 110. Alternatively, the band 106 can be a continuous band (no segments) and the attachment mechanism can expand to allow a user to attach the band to a body part and then collapse once the band is at a desired location on the body part. For example, a butterfly clasp or a single deployant clasp can be used as an attachment mechanism.
The one or more attachment mechanisms 112, 114 can operate as a coarse adjustment in that the user is able to attach the band to a body part, but the band may not be attached as tightly to the body part as desired or needed. For example, a band may be able to shift on the body part (e.g., wrist) or slide around the body part while attached to the body part. Additionally or alternatively, the band may be sufficiently loose on the body part such that one or more components (e.g., sensors) in the electronic device 100 and/or in the band 106 may not be able to operate, or may not function as well due to the band's loose fit on the body part.
As one example, a photoplethysmogram (PPG) sensor may be located at the bottom surface of the electronic device 100 (the surface that is near or contacts the body part of the user). The PPG sensor emits light toward the body part and receives a portion of the light that reflects back toward the sensor. If the band 106 is too loose, the PPG sensor may not be able to determine a health measurement (e.g., pulse rate) for a user. Alternatively, the movement of the band 106 can create motion artifacts in the signals used to determine a health measurement, which can cause errors in the health measurement.
Example embodiments are described herein that include an incremental adjustment mechanism that can be separate from an attachment mechanism or may be included in an attachment mechanism. The attachment mechanism can produce an initial fit or tightness and the incremental adjustment mechanism can adjust the initial tightness. The incremental adjustment mechanism is configured to allow a user to adjust the length, fit, or tightness of the wearable band more finely than the attachment mechanism. Various example incremental adjustment mechanisms are described in conjunction with
The first band segment 202 includes a first band sub-segment 210 and a second band sub-segment 212. An incremental adjustment mechanism 214 is configured to move at least one band sub-segment with respect to the other band sub-segment to increase or decrease the tightness of the band. In one embodiment, the first and second band sub-segments 210, 212 are coupled together and cannot be separated from one another. In another embodiment, the first and second band sub-segments 210, 212 can be disassembled from one another.
By turning the dial 216 clockwise or counter-clockwise, one or both band sub-segments 210, 212 move in one of two directions as shown by arrow 218. Moving the band sub-segments 210, 212 closer together reduces the size of the gap 220 (down to a minimum size) and incrementally increases the tightness of the band, while moving the band sub-segments 210, 212 farther apart increases the size of the gap 220 (up to a maximum size) and incrementally decreases the tightness of the band. In the illustrated embodiment, the minimum size of the gap 220 is reached when the edge 222 of the dial 216 contacts or nearly contacts the edge 224 of the first band sub-segment 210. The maximum size of the gap 220 can be determined in one of several ways. For example, the dial 216 can have a limited rotation distance, which in turn limits the separation distance between the two band sub-segments 210, 212. Additionally or alternatively, the maximum size of the gap 220 may be based on the distance D between two of the openings 206. For example, the maximum size of the gap 220, and therefore the maximum achievable separation distance between the two band sub-segments 210, 212, can be a fraction of the distance D (e.g., 50% of D).
Other embodiments can configure the incremental adjustment mechanism differently. As one example, the dial 216 can be configured to move only a single band sub-segment. Alternatively, an eccentric cam apparatus may be configured to move one band sub-segment with respect to the other band sub-segment.
In the embodiments shown in
The attachment mechanism 700 unfolds or opens to position the band 702 on a user's body part (e.g., wrist). The user folds or closes the attachment mechanism 700 to secure to the band on the body part. The attachment mechanism 700 includes a first wing 706 that rotates (e.g., folds and unfolds) with respect to a second wing 708 when the attachment mechanism 700 closes and opens, respectively. An incremental adjustment mechanism 710 includes a dial 712 positioned in a top segment 714 of the attachment mechanism 700. In one embodiment, the dial 712 can be configured to open the attachment mechanism 700 by pressing downward on the dial 712. For example, a tab (not shown) that extends out from the edge 716 of the top segment 714 may engage with an opening (not shown) in the edge 718 of the band 702 when the attachment mechanism 700 is closed. The tab can retract out of the opening when the dial 712 is pushed downward.
The top segment 714 includes two band sub-segments 720, 722 that are configured to move relative to one another. The incremental adjustment mechanism 710 is configured to move at least one band sub-segment to increase or decrease the tightness of the band 702.
As shown in
Any suitable type of incremental adjustment mechanism may be used. For example, in one embodiment, the incremental adjustment mechanism shown in
The incremental adjustment mechanism includes the first and second posts 908, 910. When a user attaches the band 900 to a body part, the user can insert either the first or second post into a respective opening 912. In one embodiment, the distance D between the first and second posts 908, 910 can be a fraction of the distance D′ between two adjacent openings 912. For example, D may be approximately half of the distance of D′. The two posts 910, 912 permit a user to fit the band around a body part (e.g., a wrist) more tightly or loosely compared to the fit obtained with a single post.
In some embodiments, the rotatable elliptical substrate 1004 is coupled with a rotating apparatus (not shown) that is configured to permit the rotatable elliptical substrate 1004 to partially rotate and move the post 1002 from one end of the major axis of the elliptical substrate to the other end of the major axis and back again along the same path (e.g., the post only moves along half of the perimeter of the ellipse). In other embodiments, the rotatable elliptical substrate 1004 is coupled with a rotating apparatus (not shown) that is configured to permit the rotatable elliptical substrate 1004 to rotate completely and move the post 1002 from one end of the major axis of the elliptical substrate to the other end of the major axis and back again along the full perimeter of the ellipse.
To incrementally adjust the fit of a band, a user can rotate the post 1002 and the rotatable elliptical substrate 1004 (see arrow 1006) to position the post in a given location and produce a desired band fit. For example, when the post 1002 is positioned as shown in
In some embodiments, the material that forms the first and second band segments is a compliant or elastomer material that conforms to the post 1002 when the post 1002 is inserted into an opening in the second band segment regardless of the position of the post 1002. In other words, the post 1002 can be coupled to the same opening when the post 1002 is positioned as shown in
For example, in
Alternatively, in another embodiment the post 1102 can be positioned in one of three or more positions within region 1104. In one non-limiting example, the bottom surface of the post 1102 may be a toothed surface that mates with a similarly toothed element within the first band segment 1102. The number of positions the post 1102 can be moved to can be based on the number of teeth in the toothed element or in the toothed surface of the post 1102. A user may pull the post 1102 up to move the post from one position to another position.
In some embodiments, the material that forms the second band segment is a compliant or elastomer material that conforms to the post 1102 regardless of which position the post 1102 is located. In this manner, the post 1102 is held firmly within an opening in the second band segment and the first band segment 1100 is securely attached to the second band segment.
To incrementally adjust the fit of a band, a user can pull the post 1208 up so that the post 1208 is lifted out of one cutout. The user may then move or slide the post 1208 to mate with the other cutout. For example, as shown in
Other embodiments can configure the attachment mechanism differently. For example, a single post can be affixed to a first band segment and multiple openings formed in a second band segment. The incremental adjustment mechanism can include the shape of the post (or the shape of the portion of the post that resides within an opening). The shape is designed to provide one or more incremental adjustments in the fit of the band. In one non-limiting example, the post (or the shape of the portion of the post that resides within an opening) is an elliptical shape that produces at least one incremental adjustment by rotating the post (or the portion of the post that resides within an opening) to one of two different positions. The major axis of the elliptical shape can be positioned parallel with the length of the band for a first band fit, or the major axis of the elliptical shape may be positioned perpendicular to the length of the band for a second fit.
With respect to
An incremental adjustment mechanism 1404 includes a plate 1406 attached to movable bottom segments 1408, 1410 by inserting one fastener into opening 1412 and another fastener into opening 1414 or opening 1416. The fasteners couple with corresponding openings (not shown) in the bottom segments 1408, 1410. Any suitable fastener can be used. As one example, the fasteners may be screws.
The bottom segment 1410 can include a single opening that is configured to couple with the fastener. The fastener can be inserted into opening 1414 or opening 1416 depending on the desired tightness of the band 1302. Alternatively, the bottom segment 1410 can include one elongated opening that is configured to couple with the fastener regardless of the position of the bottom segment 1410.
In one embodiment, the plate 1406 is removably attached to at least one bottom segment to allow a bottom segment to slide with respect to the other segment. To incrementally adjust the tightness of the band 1302, a user can loosen or remove one or both fasteners in openings 1412 and 1414 (or 1416) to slide one or both bottom segments to incrementally adjust the length of the band. For example, a user can slide segment 1408 in the direction indicated by arrow 1418 to increase the length of the band 1302 (which reduces the tightness of the band 1302). Conversely, sliding the bottom segment 1408 in the opposite direction can decrease the length and increase the tightness of the band 1302. Once the bottom segment(s) 1408, 1410 are each in a particular location that produces a desired band tightness, one or both fasteners can be coupled with the opening 1412 and the opening 1414 or 1416 (and corresponding openings in the bottom segments 1408, 1410) to secure the bottom segments 1408, 1410 in their positions.
Increasing the length of the band 1302 can expand the attachment mechanism 1300 slightly. As shown in
One or both fasteners 1502, 1504 (e.g., screws) can be loosened or removed to slide at least one segment 1408, 1410 along the path 1500. Once the bottom segments 1408, 1410 are each at a desired position, the plate 1406 can be positioned over and attached to the bottom segments 1408, 1410 with the fasteners 1502, 1504. The fastener 1502 couples with the opening 1412, while the fastener 1504 couples with opening 1414 or with opening 1416 (fastener 1504 shown in phantom).
In the illustrated embodiment, the bottom segment 1410 includes two openings (not shown) that can each couple with the fastener 1504. The locations of the two openings in the bottom segment 1410 correspond to the locations of the openings 1414, 1416. To incrementally adjust the length of the band, a user can remove or loosen the fastener 1504 in one of the openings 1414 or 1416, slide one or both bottom segments 1408, 1410 to a different position, and then affix the fastener 1504 in the other opening. Alternatively, a user can remove both fasteners 1502, 1504 and the plate 1406, slide one or both bottom segments 1408, 1410 to a different position, and then affix the plate 1406 over the bottom segments 1408, 1410 by coupling the fasteners 1502, 1504 in the appropriate openings. The length of the band is increased and the tightness of the band is decreased when the fastener 1504 is in the opening 1416, and the length of the band is reduced and the tightness of the band increased when the fastener 1504 is in the opening 1414.
Other embodiments can configure the incremental adjustment mechanism differently. For example, the incremental adjustment system can include a series of openings that through the sides of both segments 1408, 1410 along path 1500. A removable pin can be inserted into one of the openings to incrementally adjust the length of a band. Alternatively, the bottom segments 1408, 1410 may couple with one plate positioned above the bottom segments and one plate positioned below the bottom segments. The opposing surfaces of the plates (e.g., top of bottom plate and bottom of top plate) can have toothed sections that at least partially mate together. The fasteners 1502, 1504 can be removed or loosened to allow a user to move one plate with respect to the other plate to incrementally adjust the tightness of the band. In such an embodiment, the bottom segment 1410 may include an elongated opening that receives a fastener regardless of the position of the bottom segment 1410, or the bottom plate may include multiple openings that may receive a fastener.
The connector 1606 is attached to a shaft 1700 positioned within an opening 1610 in the second bracket 1604. The opening 1610 extends from one side of the second bracket 1604 to the other side of the second bracket 1604. An eccentric cam 1702, 1704 is connected to each end of a connecting bar 1700. The connecting bar 1700 is positioned in the opening 1610 with the eccentric cams 1702, 1704 at each end of the opening 1610. To incrementally adjust the tightness of the band (not shown), the position of the shaft 1700 is rotated, which in turn moves the connector 1606 to adjust the distance between the first and second brackets 1602, 1604. As one example, the shaft 1700 can be rotated by inserting a tool (not shown) into the opening 1706 and rotating the shaft 1700.
The connector 1806 attaches to the second link 1804 with a rotatable shaft 1808, and to the first link 1802 with an eccentric cam 1810. The eccentric cam 1810 is configured to move the first link 1802 in the directions indicated by arrow 1812 when the position of the eccentric cam is adjusted. As one example, a tool (not shown) can be inserted into the shaft 1814 to rotate the shaft, 1814, which causes the first link 1802 to move with respect to the second link 1804 in a direction that corresponds to the rotation direction. For example, the first link 1802 moves to the right when the shaft 1814 is rotated clockwise to increase the length of the band and decrease the tightness of the band. Conversely, the first link 1802 moves to the left when the shaft 1814 is rotated counter-clockwise to decrease the length of the band and increase the tightness of the band.
