[0004] Exemplary methods and systems are directed to footwear articles having automatic lacing motors. These examples are merely representative of possible configurations. Unless otherwise stated, The components and functions are optional and may be combined or subdivided, and the operations The order may be changed, combined or sub-divided. For purposes of providing a thorough understanding of the exemplary embodiments, numerous specific details are set forth. However, it will be understood by those skilled in the art that the present subject matter may be practiced without these specific details. It will be clear to those who

[0005] Footwear articles, such as shoes, are made up of a variety of components, both traditional and non-traditional. The conventional components include the upper, sole, and laces. Alternatively, other fastening mechanisms may be included within the article of footwear to encircle and secure the wearer's foot. A non-conventional motorized lacing system engages the laces to tighten and / or Additional or alternative electronics may be used to operate and drive motors, footswitches, sensing information about the nature of the software product, providing illuminated displays and / or other sensory stimuli; A variety of functions for footwear articles can be provided, including:

[0006] Generally, especially in footwear products for the performance of athletic activities, the size of the footwear product Features such as size, shape, robustness and weight can be particularly important. If the material, for example, makes the footwear article relatively tall, heavy, and / or weak, The ability of the footwear product to be effective in performing athletic activities may be compromised.

[0007] The components of the automatic lacing system are contained within a housing and are mounted on or within the article of footwear. However, the electrical insulation layer may be located in the inner part of the sole structure, for example. Sub-components may be subject to normal forces exerted on articles of footwear, for example: When the wearer steps on a rock or other hard protrusion, a force is applied to the housing through the sole, and this force The housing may apply force or bend components contained within the housing. Therefore, for example, the battery or motor may be relatively more mechanically robust than other components. If force is applied to the controller, the risk of damage to the system increases with the printed circuit board (PCB) or may be less than when the force is applied to the electronic connector.

[0008] However, design considerations regarding height and ease of manufacture generally dictate that the sole It is recommended that the PCB be placed in close proximity to the surface of the enclosure that is most closely oriented in the direction Therefore, when a force that bends the housing is applied to the sole, This can result in an undesirable amount of force being applied to the PCB. Components of an automatic lacing system that can reduce and in turn be relatively more robust than PCBs Another component of the automatic lacing system extends through the PCB to direct force to the For example, one or more supports in the vicinity of the motor are designed in a housing in the vicinity of the sole. When a force is applied to the housing and the housing bends, the supports come into contact with other components and the PC B. The support applies at least a portion of the force to the component, not to B. Although it is not possible to completely eliminate the forces acting on the PCB, the support must limit the forces acting on the PCB to acceptable limits. Sufficient force can be directed away from the PCB to limit impact.

[0009] FIG. 1 illustrates the configuration of a powered lacing system for an article of footwear in an exemplary embodiment. FIG. 1 is an exploded view of the components of the system. The principles described with respect to clothing products apply equally to any of a variety of wearable products.

In one embodiment, the lacing system 100 may be formed The racing cable is inserted under the continuous loop of the racing cable (described below). The lid 104 is aligned with the spool in the lug engine 102. Finally, the lid 104 is attached to the midsole plate 104. The groove of the midsole plate 108 is inserted into the groove of the midsole plate 108 and fixed in the closed position, and the recess of the midsole plate 108 is fastened to the groove of the midsole plate 108. The lid 104 can capture the racing engine 102 and can be used to protect the racing engine 102 during operation. This can help maintain alignment of the wiring cables.

The motor driver 224 is configured to operate the motor 228 using the The spool 232 is rotated via the cushion 230 to rotate the wire wound around the spool 232. The processor circuit 214 applies a desired amount of tension to the lace 238. 200, the sensor 222, and the button 200. For example, a foot presence sensor may be used to determine whether to increase or decrease tension in the lace 238. 226 is capable of detecting the presence of a foot in the footwear 198, and the processor circuit 21 6 can set the tension to the current tension level. Detect movements consistent with a certain activity level, such as normal walking or vigorous physical activity For example, the processor circuit 214 may detect a relatively gentle and vigorous walking motion for casual walking. For intense physical activity, set the tension to a level consistent with that activity level. The user can press the button actuator 201 to adjust the tension as desired. A step or linear increase or decrease in can be manually commanded.

[0012] The battery 234 generally provides power to the components of the racing engine 102 and may, for example, be In a typical embodiment, the battery is a rechargeable battery. However, non-rechargeable batteries, super Alternative power sources, such as a capacitor, are also contemplated. In the illustrated example, a battery 234 is connected to the charging circuit 218. and a recharge coil 236. The recharge coil 236 is connected to the outside When the external charger 240 is placed near the external charger 240, the charging circuit 242 powers the transmission coil 244 to recharge the A current is induced in the charging coil 236, which is then charged by the charging circuit 218. 234. The battery 234 may be recharged by, for example, Alternative recharging mechanisms are contemplated, such as a piezoelectric generator.

[0013] The wireless transceiver 220 may be used in a smartphone, a wearable device, a tablet computer, or any other 246, such as a wireless LAN cable, a personal computer, or the like. In one embodiment, the wireless transceiver 220 is configured to support the Bluetooth Low Energy standard. The wireless transceiver 220 is configured to communicate in a near field communication (NFC) manner. ), 802.11 WiFi, or the like. The wireless transceiver 220 is adapted to communicate with a number of external user devices 246 and / or The wireless transceiver 220 may be configured to communicate in a number of different wireless formats. For example, entering a predetermined mode of operation or increasing or decreasing the tension of the race 238 in a stepped or linear manner. A user may control the racing engine 102, including increasing or decreasing Receive instructions from a user device 246 using an application running on the device 246 The wireless transceiver 220 may further receive, for example, the amount of tension in the race 238 or The orientation of the spool 232, the amount of charge remaining in the battery 234, and generally the lacing element Information about the racing engine 102, such as other information about the engine 102 as desired. may be transmitted to the user device 246.

[0014] FIG. 3A is an exploded view of a racing engine 102 in an exemplary embodiment. The engine 102 includes a housing 103 having an upper portion 103A and a lower portion 103B. B, and generally, except for certain components located outside the housing 103, the racing element These components include a button actuator 201 (and Associated O-rings 3 to protect the racing engine 102 from environmental conditions such as moisture 00) and is fixed to the transmission 230 via a set screw 302 and is enclosed by a lid 104. The housing 1 includes a spool 232 that holds the foot presence sensor 226 and a dielectric foam 304. 03 includes a main PCB 204, a user interface PCB 206, a motor 228, A transmission 230, a battery 234, a recharging coil 236, and a foot presence sensor The electrodes 306 and foam 308 of 226 are encapsulated.

[0015] Partially visible in the exploded view is an optical encoder unit 210. The three-dimensional encoder 310 of the optical encoder unit 210 is connected to the motor 228. A specific embodiment of the three-dimensional encoder 310 is described in the present specification. As shown in.

[0016] FIG. 3B is a view of the lower portion 103B of the housing 103 relative to the main PCB 204. 03B has a post 312 extending from an inner surface 314 of the lower portion 103B of the housing 103. As shown herein, at least one post 312 is attached to the main PCB 2. 04 (not shown). For example, when a wearer of the footwear 198 places an object When the foot is stepped on, force is applied via the midsole 110 and the plate 108 (FIG. 1), When an external force is applied to the outside of the lower portion 103B of the column portion 3, the lower portion 103B may bend. 12 shows that the bending of the lower portion 103B is caused by components with relatively low elasticity, such as the main PCB 204. Instead, a relay, such as a motor 228, a transmission 230, or a battery 234, is used. One or more contacts with relatively hard or resilient components of the sing engine 102. It is arranged to be attached to the post 312 .

[0017] 4A and 4B show an exemplary embodiment in which a force 400 is applied to the lower portion 103B. 3 is a sequential block diagram showing the function of the post 312 when the post 312 is in the As shown in FIG. 3B, a plurality of posts 312 are provided in the present invention. They may be placed in various locations according to the principles set forth herein and as described herein. In addition, the posts 312 may be positioned and configured to contact any suitable resilient component. It should be understood that this may also be done.

[0018] FIG. 4A shows a lower part 103B connected to an upper part 103A having a pillar portion 312. The pillars 312 are formed on the main PCB 204. As shown, the post extends through a hole 402 in the transmission 230. 404. In one embodiment, the gap 404 is It is smaller than the gap 406 between the inner PCB 204 and the inner surface 314. Gap 404 may be absent or may be substantially the same as gap 406. It should be understood that since no force is applied to the lower portion 103B, the lower portion 103B It is substantially flat and straight.

[0019] FIG. 4B shows the lower portion 103B bowing due to a force 400 applied to the lower portion 103B. The curvature of the lower portion 103B causes the post 312 to contact the transmission 230 with a force of 400. At least a portion of the transmission 230 is transmitted to the post 312. While the gap 404 between the slit 230 and the slit 230 is eliminated, at least some of the gap 4 06 is left between the inner surface 314 and the main PCB 204. As a result, in this embodiment, The force 400 is not applied to the relatively weak main PCB 204, but instead to the more resilient This is given to the highly reliable transmission 230.

[0020] This exaggerated illustration does not show the contact between the lower portion 103B and the main PCB 204. In actual implementation, some contact may occur between the lower part 103B and the main PCB 204. It is understood that at least a portion of the force 400 may be applied to the main PCB 204. However, it will be understood that at least the presence of the post 312 reduces the force 400. At least a portion of the wiring may be attached to the transmission 230 rather than to the main PCB 204. The force 400 applied to the main PCB 204 is larger than that when the pillars 312 are not present. As a result of the relative reduction in the thickness, the force 400 applied to the lower portion 103B The likelihood of damage to the PCB 204 may still be reduced.

[0021] 5A and 5B are side views of a racing engine 102 in an exemplary embodiment. 1 is a perspective view of the main PCB 204, the user interface PCB 206, and the motor 2 28, transmission 230, battery 234, electrodes 306, foam 308, and Components such as the charging coil 236 are housed within the top 103A and bottom 103B of the housing 103. The spool 232 is secured to the transmission 230 via a set screw 302. The upper portion 103A generally conforms to the curved contour of the motor 228.

[0022] In one embodiment, top 103A and bottom 103B are each approximately 1.5 millimeters thick. The recharging coil 236 includes a ferrite backing and is approximately 0.7 millimeters thick. The battery 234 may expand over time, resulting in a loss of approximately 7 In one embodiment, the electrodes 306 are approximately 0.25 mm thick. The foam 308 is approximately 0.5 millimeters thick and is adjacent to the battery 234. The overall thickness of the racing engine 102 is approximately 11.75 mm. In the illustrated embodiment, the motor 228 is approximately 8.5 millimeters thick. Racing engine 102 has a maximum thickness of approximately 14.55 millimeters. The racing engine 102 adjacent to the spool 232 is approximately 14.7 mm It has a thickness.

[0023] FIG. 6 illustrates a three-dimensional encoder 600 in an exemplary embodiment. The encoder 600 functions as the three-dimensional encoder 310 of the optical encoder unit 210. The three-dimensional encoder 600 is connected to a drum portion 602 and a cylindrical portion. and a fixing portion 604 configured to fix the encoder 600 to a motor shaft or the like. Mu is a drum encoder. The fixed part may be solid or may be individual parts extending between the drum part 602 and the motor, such as spokes. It may be an individual part extending between the drum part 602 and the motor.

[0024] As shown, the drum part 602 is cylindrical and has a circular cross-section, but it may be any of various suitable geometric shapes including conical, octagonal, etc. Similar to the 2D disc 300, the drum 600 includes a plurality of first segments 606, which are, for example, dark segments, and the plurality of first segments 606 are alternately arranged with a plurality of second segments 608, which are, for example, reflective segments. The plurality of first and second segments 606, 608 are arranged on the outer surface 610 of the drum part 602. The plurality of first segments 606 include, for example, dark segments. The plurality of first segments 606 are alternately arranged with a plurality of second segments 608, which are, for example, reflective segments. The plurality of first and second segments 606, 608 are arranged on the outer surface 610 of the drum part 602.

[0025] FIG. 7 is a diagram showing an optical encoder unit 700 including a 3D encoder 600 in an exemplary embodiment. The optical encoder 700 can operate as the optical encoder 210 in the block diagram of FIG. 2. The optical encoder 700 includes an optical sensor 702 in addition to the 3D encoder 600. The optical sensor 702 includes a first optical sensor 704 and a second optical sensor 706, each of which is within the optical range 708 of the 3D encoder 600. The optical range 708 is a distance at which the first and second optical sensors 704, 706 can distinguish between the plurality of first and second segments 606, 608. Thus, the optical range 708 can be different between different types of first and second optical sensors 704, 706. Due to external design requirements, a specific distance is required between the optical sensor 702 and the 3D encoder 600. The optical range 708 is a distance at which the first and second optical sensors 704, 706 can distinguish between the plurality of first and second segments 606, 608. Thus, the optical range 708 can be different between different types of first and second optical sensors 704, 706. Due to external design requirements, a specific distance is required between the optical sensor 702 and the 3D encoder 600. Due to external design requirements, a specific distance is required between the optical sensor 702 and the 3D encoder 600. ​In this case, the first and second optical sensors 704, 706 have optical sensors at least as long as the distance It may be selected to have a range 708 .

[0026] The first optical sensor 704 is disposed on a first main surface 710 of the main PCB 204. Meanwhile, the second optical sensor 708 is disposed on the second major surface 712 of the main PCB 204. In the illustrated example, the first and second optical sensors 704, 706 have a plurality of first and second segments. The vertical spacing 714 is approximately equal to the height 716 of each of the members 606, 608. The distance 714 is, for example, within about 5% of the height 716. In this manner, the first and second optical Each of the sensors 704, 706 is sensitive to the same type of segment. The first and second optical sensors 7 detect both the dark segments and the reflective segments. If each of the first optical sensor 704 and the second optical sensor 706 does not detect the same type of segment, e.g. The second optical sensor 704 detects one of the first segments 606, and the second optical sensor 7 06 detects one of the multiple second segments 608 (or vice versa). The discrepancy is immediately resolved and both the first and second optical sensors 704, 706 are of the same type. It can be expected that the segments 606, 608 of the loop can be detected.

[0027] Although a particular configuration of optical sensors 702 is illustrated, the number and orientation of the optical sensors may vary. It is noted and emphasized that the present invention may vary between implementations. An alternative embodiment of the sensor 702 may have only one individual optical sensor, whereas the optical sensor Further alternatives for sensor 702 may include three or more individual optical sensors. In various embodiments, each optical sensor is located on one of the major surfaces 710, 712 of the main PCB 204. It is placed on top of one of them.

[0028] 8A-8C are diagrams illustrating a main axis 800 of an optical encoder 700 in an exemplary embodiment. 8A shows the operation of the optical encoder unit 700 off-center relative to the The center 802 of an opening 804 in the fixed part 604 through which the motor shaft 306 passes is the main axis 800. In FIG. 8B, the opening 804 is The outer surface 610, more specifically, a plurality of first and second The segments 606, 608 are at a first distance 806 from the optical sensor 702. 8B, the optical encoder 700 has completed a half rotation relative to FIG. 8B, and the outer surface 610 is The sensor 702 is at a second distance 808, the second distance 808 being the off-center opening. The aperture 804 is fixed around the motor shaft so that the aperture 804 is greater than the first distance 806. .

[0029] The offset between the main axis 800 and the center of the aperture 802 is an unintended result of the manufacturing process. However, due to the characteristics of the optical sensor 700, it is possible to obtain a plurality of first and second segments. The apparent height 716 (FIG. 7) of each of the components 606, 608 may remain the same. As a result, such concentricity problems simply result in differences in the focal length of the optical sensor 702. The difference in focal length may be such that the optical sensor 702 is within the optical range 708 of the optical sensor 702. 702. In this manner, the optical encoder 700 can be solved in a similar manner to the optical encoder 30. If we allow for greater variation in the manufacturing process than can be tolerated in the manufacturing process of Both may be more robust to normal wear and tear during use.

[0030] FIG. 9 illustrates an alternative three-dimensional encoder 900 in accordance with an example embodiment. The three-dimensional encoder 900 may have the same characteristics as the three-dimensional encoder 600. However, Meanwhile, the three-dimensional encoder 900 drives a plurality of first and second segments 606, 608. Rather than having an outer surface of the ram portion 602, a plurality of first and second segments 606, 60 8 on the inner surface 902. The three-dimensional encoder 900 is configured such that the optical sensor 702 senses the inner surface 902. The optical sensors 700 may be arranged to detect the position of the optical sensor 700.

[0031] 10A to 10C are diagrams illustrating the configuration of three-dimensional encoders 700 and 900 according to an exemplary embodiment. The manufacturing process is shown.

[0032] In FIG. 10A, a sheet 100 of elongated first and second segments 606, 608 is shown. 0 is cut into individual strips 1002. The sheet 1000 is made of Mylar. r) and includes a plurality of dark segments, such as a first segment 606. The segments are printed on the major surface 1004 of the sheet 1000. The reflective segments, such as, are untreated or substantially untreated Mylar.

[0033] In FIG. 10B, the strip 1002 is folded over so that the major surface 1004, i.e., the printed surface, is exposed. The first end 1006 may be either the outer surface 708 or the inner surface 902 as required. The wire is secured to a second end 1008 to form a loop.

[0034] In FIG. 10C, strips 1002 are optionally connected to a frame 1010 to form a 3 The frame 1010 includes a fixed part 604 and a driver part 605. and a drum 1012 to which the strip 1002 is secured to form the drum portion 602.

[0035] Figure 11 is a diagram of a three-dimensional encoder 1100 in an exemplary embodiment. Unlike the encoders 700 and 900, the three-dimensional encoder 1100 has tabs 1102 and Gaps 1104 can be used to expose or conceal surfaces, as in the case of tabs 1102. The optical sensors 1106, 1107, 1109, 1110A, 1110B, 1110C, 1110D, 1110E, 1110F, 1110G, 1110H, 1 ...2, 1113, 1114, 1115, 1116, 1117, 08, when the gap 1104 is aligned with the optical sensors 1106, 1108, the reflected light Detecting light reflected from tab 1102 rather than its absence. The optical sensors 1106, 1108 form an angle of approximately 54 degrees between each other. 1110 for the purpose of focusing light for detection by optical sensors 1106, 1108. The three-dimensional encoder 1100 includes a slit 1112 through which light passes to focus the light. Similar to the encoders 700 and 900 , the encoder 220 is rotatably coupled to the motor 228 .

[0097] A hardware module provides information to other hardware modules and Thus, the described hardware modules are capable of communicating Multiple hardware modules can be considered to exist simultaneously. between two or more hardware modules (e.g., via appropriate circuits and buses). Communication may be achieved by signal transmission (multiple hardware modules may be different). In an embodiment where these hardware modules are configured or instantiated at the time Communication between the hardware modules may involve, for example, storing information in a memory structure that is accessed by multiple hardware modules. This may be accomplished through the storage and retrieval of information. For example, a hardware module may Performing an operation and storing the output of the operation in a communicatively connected memory device Then, a further hardware module may later access the memory device. The hardware module may receive and process the input or It can also initiate communication with output devices and send resources (e.g. collections of information) can be operated.

[0098] Various operations of the example methods described herein may be performed (e.g., by software) ) temporarily configured or permanently configured to perform related operations, The method may be implemented, at least in part, by one or more processors. Whether embedded or permanently configured, these processors are A processor implementation operable to perform one or more operations or functions described herein. In this specification, a "processor-implemented module" may be Refers to a hardware module implemented using one or more processors.

[0099] Similarly, the methods described herein may be implemented in a processor, as an example of hardware, that includes at least For example, at least some of the operations of the method may be implemented in one or more The present invention may be implemented by one or more processors or processor-implemented modules. Multiple processors may be used in a "cloud computing" environment or in a "software Software as a Service (SaaS) that operates to support the execution of related operations. For example, at least some of the operations may be performed by a computer (such as a machine that includes a processor). These actions may be performed by a group of computers (over the Internet) Networks (such as ISPs) and Application Program Interfaces (APIs) The information may be accessed by any one or more suitable interfaces.

[0100] The performance of certain operations may be distributed among one or more processors, or may be performed by one machine. In one exemplary embodiment, the In an embodiment, one or more processors or processor-implemented modules may include: may be located in one geographic location (such as an office environment, or within a server farm). In an exemplary embodiment of the present invention, the one or more processors or processor-implemented modules include: It may be distributed across multiple geographic locations.

[0101] Some parts of this specification are described as being bit-structured in a machine's memory (such as a computer memory). An algorithm or record of an operation on data stored as a binary digital signal These algorithms or symbolic representations are commonly used in the data processing arts. are examples of techniques used by practitioners in the art to communicate the content of their work to others in the art. As used herein, an "algorithm" is defined as a self-consistent sequence of steps leading to a desired result. In this context, algorithms and operations include operations or similar processes involving the manipulation of physical quantities. Usually, but not necessarily, these quantities are calculated by machines. by electrical, magnetic or optical means capable of storing, accessing, transferring, combining, comparing or otherwise manipulating the information. Primarily for reasons of common usage, the terms "data", "content", "video" "value", "element", "symbol", "character", "term", "number", "quantity", etc. It is sometimes convenient to refer to these signals using the words are merely convenient labels to be associated with the appropriate physical quantities.

[0102] Unless otherwise specified, "processing," "computing," "calculation," "decision," "provision" and "provisioning" are used interchangeably. Descriptions herein using words such as "display," "display," and the like, may refer to one or more non-volatile memory, or any suitable combination thereof) In other machine components that receive, store, transmit, or display data, A machine (such as a computer) that manipulates or transforms data represented as quantities (magnetic, optical, etc.) In addition, unless otherwise specified, "a" or "a The term "n" includes one or more instances, as is common in patent documents. Finally, in this specification, unless expressly stated otherwise, the term "or" is used in a non-exclusive sense. Refers to "or."
