Exemplary methods and systems are directed to footwear products having automatic lacing motors. These examples are merely representative of possible forms. Unless otherwise stated, components and features may be optional, combined or subdivided, and acts may be permuted, combined or subdivided. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the exemplary embodiments. However, it will be apparent to those skilled in the art that the present subject matter may be practiced without these specific details.

In general, especially for footwear products for the performance of athletic activities, characteristics such as size, shape, robustness and weight of the footwear product can be of particular importance. If components of a footwear product, for example, make the footwear product relatively tall, heavy, and/or fragile, the footwear product's ability to be effective in performing athletic activities may be impaired.

The components of the automatic lacing system may be contained within the housing and positioned on or within the footwear article, for example within the sole structure. However, electronic components may be susceptible to the normal forces exerted on footwear products. For example, if the wearer steps on a rock or other hard protrusion, forces may be applied to the housing through the sole, causing the housing to flex and apply forces to components housed within the housing. Certain components may be relatively mechanically robust than other components. Thus, for example, if a force is applied to a battery or a motor, the risk of damage to the system may be less than if a force is applied to a printed circuit board (PCB) or electronic connector.

However, design considerations regarding height and ease of manufacture may make it desirable to locate the PCB generally proximate to the surface of the housing, typically closest to the sole. Therefore, if a force is applied to the sole that causes the housing to flex, it may result in an undesirable amount of force being applied to the PCB. Another component of the auto lacing system that extends through the PCB to reduce the forces that tend to be applied to the PCB and instead directs the forces to components of the auto lacing system that can be relatively more robust than the PCB. One or more supports in the vicinity of a component, for example a motor, are designed in the housing close to the sole. When a force is applied to the housing and the housing flexes, the support contacts the other component and applies at least a portion of the force to that component rather than onto the PCB. Although the support cannot prevent any force from being applied to the PCB, the support can direct sufficient force away from the PCB to limit the force applied to the PCB to acceptable limits.

FIG. 1 is an exploded view of components of a motorized lacing system for an article of footwear in an exemplary embodiment. Although the present system is described with respect to footwear products, it will be appreciated and understood that the principles described with respect to footwear products may be applied to any of a variety of wearable products as well. The electric lacing system 100 shown in FIG. 1 includes a lacing engine 102 having a housing structure 103, a lid 104, an actuator 106, a midsole plate 108, a midsole 110, and an outsole 112. FIG. 1 is a diagram showing the basic assembly sequence of the components of an automatic racing footwear platform. In the electric lacing system 100, the midsole plate 108 is first fixed within the midsole. The actuator 106 is then inserted into the lateral opening of the midsole plate opposite the interface button that is recessed into the outsole 112. Racing engine 102 is then placed within the racing engine cavity of midsole plate 108. In one embodiment, lacing system 100 is inserted under a continuous loop of lacing cable, and the lacing cable is aligned with a spool within lacing engine 102 (described below). Finally, the lid 104 is inserted into the groove of the midsole plate 108, fixed in the closed position and clipped into the recess of the midsole plate 108. The lid 104 can capture the racing engine 102 and can help maintain racing cable alignment during operation.

FIG. 2 schematically shows a block diagram of the components of the electric racing system 100 in an exemplary embodiment. System 100 includes, but need not include all, components of an electric lacing system, such as a lacing engine 102, a midsole plate 108, and a footwear sole 198. The illustrated system 100 includes an interface button 200, an interface button actuator 201, a foot presence sensor 202, and a racing engine housing 103 that houses a main PCB 204 and a user interface PCB 206. The user interface PCB 206 includes a button 200, one or more light emitting diodes (LEDs) 208 that may illuminate the button actuator 201 or provide external visible illumination of the footwear product, an optical encoder unit 210, and the LED 208. and an LED driver 212 that can supply power. Main PCB 204 includes processor circuitry 214, electronic data storage 216, battery charging circuitry 218, wireless transceiver 220, one or more sensors 222, such as an accelerometer and gyroscope, and motor driver 224.

Racing engine 102 further includes a foot presence sensor 226, such as a capacitive sensor, a motor 228, a transmission 230, a spool 232, a battery or power source 234, and a charging coil 236. Processor circuit 214 is configured, using instructions from electronic data storage 216, to cause motor driver 224 to operate motor 228 to rotate spool 232 via transmission 230 to cause the spool 232 to be wound around spool 232. Apply the desired amount of tension to the lace 238. Processor circuit 214 may receive input from various sources, such as foot presence sensor 226, sensor 222, and button 200, and determine to increase or decrease the tension in lace 238 according to instructions. For example, foot presence sensor 226 can detect the presence of a foot within footwear 198 and processor circuit 216 can set the tension to the current tension level. The sensor 222 can detect movements consistent with a particular activity level, such as, for example, casual walking, strenuous physical activity, and the processor circuit 214 can detect movements that are relatively gentle for casual walking and vigorous In the case of physical activity, the tension can be set to a level that is relatively tight and consistent with the level of activity. A user can press button actuator 201 to manually command a stepwise or linear increase or decrease in tension as desired.

Battery 234 typically provides power to the components of racing engine 102, and in the exemplary embodiment is a rechargeable battery. However, alternative power sources such as non-rechargeable batteries, supercapacitors, etc. are also contemplated. In the illustrated example, battery 234 is coupled to charging circuit 218 and recharging coil 236. When recharging coil 236 is placed in close proximity to external charger 240, charging circuit 242 powers transmitting coil 244 to induce a current in recharging coil 236, which is then used by charging circuit 218 to recharge battery 234. used to do. Alternative recharging mechanisms are contemplated, such as a piezoelectric generator located within footwear 198, for example.

Wireless transceiver 220 is configured to wirelessly communicate with a remote user device 246, such as a smartphone, wearable device, tablet computer, personal computer, etc. In one embodiment, the wireless transceiver 220 is configured to communicate in a Bluetooth low energy manner, while the wireless transceiver 220 is configured to communicate using Near Field Communication (NFC), 802.11 Communication may be via any suitable wireless method, including WiFi and the like. Additionally, wireless transceiver 220 may be configured to communicate with multiple external user devices 246 and/or with multiple different wireless modalities. Wireless transceiver 220 can be used on user equipment 246 to provide control of racing engine 102, including, for example, entering a predetermined mode of operation or increasing or decreasing the tension of lace 238 in steps or linearly. An operating application may be used to receive instructions from user device 246. The wireless transceiver 220 further provides information regarding the racing engine 102, such as, for example, the amount of tension in the lace 238 or the orientation of the spool 232, the amount of charge remaining in the battery 234, and other information desired regarding the racing engine 102 in general. Information may be sent to user device 246.

FIG. 3A is an exploded view of racing engine 102 in an exemplary embodiment. Racing engine 102 includes a housing 103, which includes a top 103A and a bottom 103B, and generally houses racing engine 102, except for certain components located outside of housing 103. These components include a button actuator 201 (and associated O-ring 300 to protect the racing engine 102 from environmental conditions such as moisture), which is secured to the transmission 230 via a set screw 302 and secured to the lid 104. An enclosed spool 232 and dielectric foam 304 of foot presence sensor 226 are included. Enclosed within the housing 103 are a main PCB 204, a user interface PCB 206, a motor 228, a transmission 230, a battery 234, a recharging coil 236, and the electrodes 306 and foam 308 of the foot presence sensor 226.

Partially visible in the exploded view is optical encoder unit 210. Specifically, the three-dimensional encoder 310 of the optical encoder unit 210 is coupled to the motor 228 and rotates as the motor rotates. A specific embodiment of a three-dimensional encoder 310 is shown herein.

FIG. 3B is a view of the bottom 103B of the housing 103 relative to the main PCB 204. The bottom portion 103B includes struts (pillars) 312 extending from the inner surface 314 of the bottom portion 103B of the housing 103. As shown herein, at least one post 312 extends through a hole (not shown) in the main PCB 204. For example, when the wearer of the footwear 198 steps on an object, force is applied through the midsole 110 and the plate 108 (FIG. 1), and when an external force is applied to the outside of the bottom 103B of the housing 103, the bottom 103B Can be bent. The flexing of the bottom portion 103B of the struts 312 allows one or more struts 312 to connect to a component of the racing engine 102, such as the motor 228, transmission 230, or battery 234, rather than a relatively less resilient component, such as the main PCB 204. placed in contact with a relatively hard or resilient component. As shown, the struts 312 are shaped like plus signs to efficiently distribute forces. However, it should be recognized and understood that middle portion 312 may be of any suitable shape or size.

4A and 4B are sequential block diagrams illustrating the function of strut 312 when force 400 is applied to bottom 103B in an exemplary embodiment. The block diagrams are simplified and exaggerated for illustrative purposes. As shown in FIG. 3B, the plurality of struts 312 can be placed in various positions according to the principles presented herein, and as described herein, the struts 312 can be arranged in any suitable resilient manner. It should be understood that the device may be arranged and configured to contact a component having a property.

FIG. 4A shows the bottom 103B connected to the top 103A, with struts 312 projecting from the inner surface 314 of the bottom 103B. Posts 312 extend through holes 402 formed in main PCB 204. As shown, the struts do not contact the transmission 230 and have a gap 404 therebetween. In various embodiments, gap 404 is smaller than gap 406 between main PCB 204 and inner surface 314. However, it should be understood that gap 404 may be absent or gap 404 may be substantially identical to gap 406. Since no force is applied to the bottom portion 103B, the bottom portion 103B is substantially flat and straight.

FIG. 4B shows the bottom 103B curved due to the force 400 applied to the bottom 103B. The curvature of bottom 103B causes strut 312 to contact transmission 230 and transmit at least a portion of force 400 to transmission 230. While the gap 404 between the post 312 and the transmission 230 is eliminated, at least some gap 406 is left between the inner surface 314 and the main PCB 204. As a result, in this example, force 400 is not applied to the relatively weak main PCB 204, but instead to the more resilient transmission 230.

Although this exaggerated description does not show any contact between the bottom 103B and the main PCB 204, it is understood that in an actual implementation there may be some contact between the bottom 103B and the main PCB 204 and/or at least part of the force 400. It will be appreciated and understood that the section is attached to the main PCB 204. However, at least the presence of struts 312 facilitates applying at least a portion of force 400 to transmission 230 rather than main PCB 204. The relative reduction in the magnitude of the force 400 applied to the main PCB 204 compared to the absence of the struts 312 may still reduce the likelihood that the main PCB 204 will be damaged by the force 400 applied to the bottom 103B.

5A and 5B are side and perspective views of racing engine 102 in an exemplary embodiment. Components such as main PCB 204, user interface PCB 206, motor 228, transmission 230, battery 234, electrodes 306, foam 308, and recharging coil 236 are housed within the top 103A and bottom 103B of the housing 103. Spool 232 is secured to transmission 230 via set screw 302. Upper portion 103A generally conforms to the curved profile of motor 228.

In one example, top 103A and bottom 103B are each approximately 1.5 millimeters thick. Recharging coil 236 is approximately 0.7 millimeters thick, including the ferrite backing. Battery 234 is approximately 7.5 millimeters thick to account for expansion of battery 234 over time. In one example, electrode 306 is approximately 0.25 mm thick, foam 308 is approximately 0.5 mm thick, and the overall thickness of racing engine 102 proximate battery 234 is approximately 11.75 mm. . In one example, motor 228 is approximately 8.5 millimeters thick and racing engine 102 adjacent motor 228 has a maximum thickness of approximately 14.55 millimeters. In one example, racing engine 102 adjacent spool 232 has a thickness of approximately 14.7 millimeters.

FIG. 6 is a diagram illustrating a three-dimensional encoder 600 in an exemplary embodiment. Three-dimensional encoder 600 may function as three-dimensional encoder 310 of optical encoder unit 210. Three-dimensional encoder 600 is a drum encoder and includes a drum part 602 and a fixing part 604 connected to a cylindrical part and configured to fix three-dimensional encoder 600 to a motor shaft or the like. The fixed portion may be solid or may be a discrete portion, such as a spoke extending between the drum portion 602 and the motor.

As shown, drum portion 602 is cylindrical and has a circular cross-section, but may be any of a variety of suitable geometric shapes, including conical, octagonal, and the like. Similar to the two-dimensional disk 300, the drum 600 includes a plurality of first segments 606, e.g., dark segments, and a plurality of first segments 606, e.g., reflective segments, a plurality of second segments 608. are arranged alternately. A plurality of first and second segments 606, 608 are disposed on an outer surface 610 of drum portion 602.

FIG. 7 is a diagram illustrating an optical encoder unit 700 including a three-dimensional encoder 600 in an exemplary embodiment. Optical encoder 700 may operate as optical encoder 210 in the block diagram of FIG. Optical encoder 700 includes, in addition to three-dimensional encoder 600, an optical sensor 702 that includes a first optical sensor 704 and a second optical sensor 706, each within an optical range 708 of three-dimensional encoder 600. The optical range 708 is the distance at which the first and second optical sensors 704, 706 can distinguish between the plurality of first and second segments 606, 608. Accordingly, the optical range 708 may differ between different types of first and second optical sensors 704, 706. If external design requirements require a certain distance between the optical sensor 702 and the three-dimensional encoder 600, the first and second optical sensors 704, 706 have an optical range at least as long as that distance. 708.

The first optical sensor 704 is located on the first major surface 710 of the main PCB 204, while the second optical sensor 708 is located on the second major surface 712 of the main PCB 204. In the illustrated example, the vertical spacing 714 of the first and second optical sensors 704, 706 is approximately equal to the height 716 of each one of the plurality of first and second segments 606, 608, e.g. Approximately within 5%. Therefore, each of the first and second optical sensors 704, 706 both attempt to detect the same type of segment, ie, detect dark or reflective segments together. If the first and second optical sensors 704, 706 each do not detect segments of the same type, for example, the first optical sensor 704 detects one of the plurality of first segments 606 and the second If the optical sensor 706 of the first and second optical sensors 706 detects one of the plurality of second segments 608 (or vice versa), this mismatch is immediately resolved and the first and second optical sensors 704, 706 It is expected that both will detect segments 606, 608 of the same type.

It is important to point out and emphasize that although a particular configuration of optical sensors 702 is illustrated, the number and orientation of optical sensors may vary between different implementations. Thus, in one embodiment, an alternative to optical sensor 702 may have only one individual optical sensor, while further alternatives to optical sensor 702 include three or more individual optical sensors. But that's fine. However, in various embodiments, each optical sensor is located on one of the major surfaces 710, 712 of the main PCB 204.

8A-8C illustrate operation of optical encoder unit 700 off-center with respect to main axis 800 of optical encoder 700 in an exemplary embodiment. In FIG. 8A, the center 802 of the opening 804 in the fixed portion 604 through which the motor shaft 306 passes is offset by a predetermined distance with respect to the main axis 800. In FIG. 8B, with the aperture 804 fixed around the shaft, the outer surface 610, and more specifically the plurality of first and second segments 606, 608, are at a first distance 806 from the optical sensor 702. come. In FIG. 8C, optical encoder 700 has completed a half-rotation with respect to FIG. is fixed around the motor shaft and is therefore greater than the first distance 806.

The offset between the main axis 800 and the aperture center 802 may be an unintended result of the manufacturing process. However, due to the characteristics of the optical sensor 700, the apparent height 716 (FIG. 7) of each of the plurality of first and second segments 606, 608 may remain the same. As a result, such concentricity issues may simply result in differences in the focal length of the optical sensor 702. The focal length difference may be resolved by the optical sensor 702 within the optical range 708 of the optical sensor 702. In this manner, the optical encoder 700 may tolerate greater variation in the manufacturing process than could be tolerated in the manufacturing process of the optical encoder 300, and may be more robust to normal wear and tear during use.

FIG. 9 is a diagram illustrating an alternative example of a three-dimensional encoder 900 in an exemplary embodiment. 3D encoder 900 may have the same characteristics as 3D encoder 600. However, instead of having a plurality of first and second segments 606, 608 on the outer surface of the drum portion 602, the three-dimensional encoder 900 includes a plurality of first and second segments 606, 608 on the inner surface 902. Three-dimensional encoder 900 is arranged such that optical sensor 702 senses inner surface 902, and can be utilized in a similar arrangement to that of optical sensor 700.

10A-10C illustrate the manufacturing process of a three-dimensional encoder 700, 900 in an exemplary embodiment.

In FIG. 10A, a sheet 1000 of elongated plurality of first and second segments 606, 608 is cut into individual strips 1002. Sheet 1000 is made of any suitable material, such as Mylar, and dark segments, such as a plurality of first segments 606, are printed on major surface 1004 of sheet 1000. The reflective segments, such as the plurality of second segments 608, are untreated or substantially untreated mylar.

In FIG. 10B, the strip 1002 is folded so that the major surface 1004, or printing surface, is either the outer surface 708 or the inner surface 902, as desired. First end 1006 is secured to second end 1008 to create a loop.

In FIG. 10C, strip 1002 is optionally coupled to frame 1010 to form three-dimensional encoder 700, 900. Frame 1010 includes a securing portion 604 and a drum 1012 that secures strip 1002 to form drum portion 602.

FIG. 11 is a diagram of a three-dimensional encoder 1100 in an exemplary embodiment. Unlike 3D encoders 700, 900, 3D encoder 1100 uses tabs 1102 and gaps 1104, providing a surface that reflects light in the case of tabs 1102 and a surface that does not reflect light in the case of gaps. Provide the missing parts. Optical sensors 1106, 1108 detect light reflected from tab 1102, and when gap 1104 is aligned with optical sensors 1106, 1108, there is no reflected light. In one example, optical sensors 1106, 1108 form an approximately 54 degree angle between each other. Beam break 1110 includes a slit 1112 to focus the light that passes through the slit for detection by optical sensors 1106, 1108. Three-dimensional encoder 1100, like other encoders 700, 900, is rotatably coupled to motor 228.

Throughout this specification, components, acts, or structures that are described as one instance can be implemented by multiple instances. Although the individual acts of one or more methods are illustrated and described as separate acts, one or more of the individual acts may be performed simultaneously and the acts need not be performed in the order illustrated. do not have. Structures and functionality presented as separate components in example configurations may be implemented as a combined structure or component. Similarly, structures and functionality presented as one component may also be implemented as separate components. These and other variations, modifications, additions, and improvements are within the scope of the subject matter herein.

Certain embodiments are described herein as including logic or multiple components, modules, or mechanisms. A module may constitute either a software module (eg, code implemented on a machine-readable medium or a transmitted signal) or a hardware module. A "hardware module" is a tangible unit capable of performing a particular operation and may be configured or arranged in a particular physical manner. In various exemplary embodiments, one or more computer systems (e.g., a standalone computer system, a client computer system, or a server computer system) or one or more hardware modules of a computer system (e.g., a processor or (groups of) may be configured by software (e.g., an application or portion of an application) as a hardware module that operates to perform particular operations as described herein.

In some embodiments, hardware modules may be implemented electronically, mechanically, or any suitable combination thereof. For example, a hardware module may include dedicated circuitry or logic permanently configured to perform a particular operation. For example, the hardware module may be a field programmable gate array (FPGA) or a special purpose processor such as an ASIC. Hardware modules may include programmable logic or circuitry that is temporarily configured by software to perform specific operations. For example, a hardware module may include software contained on a general purpose processor or other programmable processor. The decision whether to implement a hardware module with mechanically dedicated permanently configured circuitry or with temporarily configured (e.g., software configured) circuitry is a cost and time decision. It may be done by consideration.

Accordingly, the term "hardware module" should be understood to encompass tangible entities, which may be physically configured, permanently configured (e.g., hardwired), or temporarily configured (e.g., is to be understood as an entity that is programmed) to operate in a certain manner or perform predetermined operations as described herein. As used herein, "hardware implemented module" refers to a hardware module. Given embodiments in which hardware modules are temporarily configured (eg, programmed), each hardware module does not necessarily need to be configured or instantiated in any one instance. For example, if the hardware module includes a general-purpose processor that is configured by software to be a special-purpose processor, the general-purpose processor may be configured at various times as different special-purpose processors (e.g., as containing different hardware modules). can be configured. Thus, the software may cause the processor to configure a particular hardware module at one time and a different hardware module at a different time, for example.

Hardware modules can provide information to and receive information from other hardware modules. Accordingly, the described hardware modules may be considered communicatively connected. When multiple hardware modules are present simultaneously, communication may be accomplished by signal transmission (eg, via appropriate circuits and buses) between two or more hardware modules. In embodiments where multiple hardware modules are configured or instantiated at different times, communication between these hardware modules may occur, for example, through the storage and retrieval of information in memory structures that are accessed by the multiple hardware modules. may be achieved. For example, a hardware module may perform an operation and store the output of the operation in a communicatively coupled memory device. Additional hardware modules may then access the memory device at a later time to retrieve and process the stored output. Hardware modules can also initiate communications with input or output devices and manipulate resources (eg, collections of information).

Various acts of the example methods described herein may be performed by one or more temporarily configured (e.g., by software) or permanently configured to perform the associated acts. may be executed, at least in part, by a processor. Whether temporarily or permanently configured, these processors may include processor-implemented modules that operate to perform one or more operations or functions described herein. Can be configured. As used herein, "processor-implemented module" refers to a hardware module implemented using one or more processors.

Similarly, the methods described herein may be implemented at least partially in a processor as an example of hardware. For example, at least some of the operations of the method may be performed by one or more processors or processor-implemented modules. Additionally, one or more processors may operate in a "cloud computing" environment or as a "software as a service" (SaaS) to support performance of related operations. For example, at least some operations may be performed by a group of computers (as one example of a machine including a processor), and these operations may be performed by a network (such as the Internet) and one (such as an application program interface (API)). It may be accessed by one or more suitable interfaces.

Execution of a particular operation may be distributed among one or more processors and may reside within one machine or may be located across multiple machines. In certain exemplary embodiments, one or more processors or processor-implemented modules may be located at one geographic location (such as in a home environment, office environment, or server farm). In other example embodiments, one or more processors or processor-implemented modules may be distributed across multiple geographic locations.

Some portions of this specification are presented as algorithms or symbolic representations of operations on data stored as bits or binary digital signals in a machine's memory (such as a computer memory). These algorithms or symbolic representations are examples of techniques used by those skilled in the data processing arts to convey the substance of their work to others skilled in the art. As used herein, an "algorithm" is a coherent sequence of operations or similar processing that motors a desired result. In this context, algorithms and operations include physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical, magnetic, or optical signals capable of being stored, accessed, transferred, combined, compared, and otherwise manipulated by a machine. Primarily for reasons of common usage, such as "data", "content", "bits", "value", "element", "symbol", "character", "term", "number", "quantity", etc. It is sometimes convenient to refer to these signals using the word . However, these words are just convenient labels associated with the appropriate physical quantities.

Unless stated otherwise, references herein to words such as "processing," "computing," "computing," "determining," "presenting," "displaying," etc. refer to one or more (volatile) physical (e.g., electronic, magnetic, or optical) memory, register, or other machine component that receives, stores, transmits, or displays information; May refer to the process of a machine (such as a computer) that manipulates or transforms data expressed as a quantity. Furthermore, unless stated otherwise, the term "a" or "an" herein includes one or more instances, as is common in patent documents. Finally, in this specification, unless stated otherwise, the term "or" refers to a non-exclusive "or."
