[0003] The present invention relates to a fluid distribution system and / or a foot support system in footwear or other foot-receiving devices. At least some aspects of the present invention relate to fluid distributors, fluid transfer systems, sole structures, fluid flow control systems, foot support systems, footwear articles, and / or other foot-receiving devices that include components (e.g., manifolds, connectors, fluid transfer systems, electronic controllers, etc.) for selectively moving fluid into, within, and / or out of a sole structure (or other foot support member) and / or a footwear article (or other foot-receiving device). With such a system, the fluid pressure (e.g., foot support pressure, fluid container pressure) in one or more fluid-filled bladders (e.g., foot support bladders (plural)) and / or one or more fluid reservoirs and / or containers included in the system as a whole may be altered and controlled.

Background Art

[0004] Conventional footwear articles include two main elements: an upper and a sole structure. The upper may provide a foot covering that firmly receives the foot and positions that foot relative to the sole structure. Additionally, the upper may have a configuration that protects the foot and provides breathability, thereby cooling the foot and allowing sweat to escape. The sole structure may be secured to the lower surface of the upper and generally positioned between the foot and any contact surface. The sole structure may provide traction and control potentially harmful foot movements, such as excessive inward rolling, in addition to attenuating ground reaction forces and absorbing energy.

[0005] The upper forms a void within the footwear for receiving the foot. The void has the general shape of the foot, and access to the void is provided by an ankle opening. Thus, the upper extends over the entire top and toe regions of the foot, along the inner and outer sides of the foot, and around the heel region of the foot. A lacing system is often incorporated into the upper so that the user can selectively change the size of the ankle opening and, thus, change certain dimensions of the upper, particularly the circumferential length, to accommodate feet of various sizes. Additionally, the upper may include a tongue that extends under the lacing system to enhance the comfort of the footwear (e.g., to adjust the pressure exerted on the foot by the shoe laces). Further, the upper may include a heel counter for restricting or controlling heel movement.

[0006] As used herein, the term "footwear" means any kind of wearable apparel for the feet, and this term includes, but is not limited to, all kinds of shoes, boots, sneakers, sandals, rubber sandals, beach sandals, mules, indoor shoes, slippers, sports shoes (such as golf shoes, tennis shoes, baseball spikes, soccer or football spikes, ski boots, basketball shoes, cross-training shoes, etc.). As used herein, the term "foot receiving device" means any device into which a user disposes at least some parts of his or her feet. In addition to all kinds of "footwear", foot receiving devices include, but are not limited to, bindings or other devices for fixing the feet in snow skis, cross-country skis, water skis, snowboards, etc., bindings, clips, or other devices for fixing the feet in pedals used in bicycles, exercise equipment, etc., bindings, clips, or other devices for receiving the feet during the play of video games or other games. A "foot receiving device" may include (a) one or more "foot covering members" (e.g., similar to the upper component of footwear) that help position the feet relative to other components or structures, and (b) one or more "foot supporting members" (e.g., similar to the sole structure component of footwear) that support at least some parts (plural possible) of the bottom surface of the user's feet. The "foot supporting member" may include components for and / or functioning as the midsole and / or outsole of footwear (or components that provide corresponding functions in non-footwear type foot receiving devices).

[0007] This application and / or the claims use adjectives such as "first", "second", "third", etc. to identify specific components and / or features related to this technology. These adjectives are used merely for convenience, for example, to assist in maintaining the distinction between components and / or features of a particular structure. The use of these adjectives should not be construed as requiring a particular order or arrangement of the components and / or features being considered. Also, even if these specific adjectives are used in the specification for a particular structure, it is not necessary to use the same adjectives in the claims to refer to the same parts (for example, a component or feature called "third" in the specification may correspond to any numerical adjective used for that component or feature in the claims).

[0008] As used herein, "manifold" means a component having a surface or housing that defines or supports one or more ports through which a fluid (e.g., gas or liquid) can enter and / or exit the component. As used herein, "port" means an opening through a component that allows a fluid (e.g., gas or liquid) to pass from one side of the opening to the other. Optionally, a "port" may include a connector structure for engaging another object, such as a fluid line, tube, or another connector. When including a connector structure, the "port" may form, for example, a male connector structure, a female connector structure, or an abutting surface connection structure. The object(s) connected to the "port" may be fixedly connected or releasably connected. Additionally or alternatively, the object(s) connected to the "port" may be fixedly or releasably attached to the inner surface of the opening through the wall of the component in which the opening is defined.

DETAILED DESCRIPTION OF THE INVENTION

[0061] In the following description of various embodiments of fluid distributors, fluid transfer systems, fluid flow control systems, sole structures, footwear structures, and their components according to the present technology, reference is made to the accompanying drawings, which form a part hereof, and which illustrate, by way of example, various exemplary structures and environments in which aspects of the present technology may be practiced. It is to be understood that other structures and environments may be utilized and structural and functional changes may be made to the specifically described structures, functions, and methods without departing from the scope of the present technology. I. General Description of Aspects of the Present Technology

[0062] Aspects of the present technology relate to, for example, fluid distributors, fluid flow control systems, foot support systems, sole structures, footwear articles, and / or other foot receiving devices of the types described and / or claimed below, and / or illustrated in the accompanying drawings. Such fluid distributors, fluid flow control systems, foot support systems, sole structures, footwear articles, and / or other foot receiving devices may include any one or more of the structures, components, features, characteristics, and / or operating conditions of the embodiments described and / or claimed below, and / or illustrated in the accompanying drawings, including, but not limited to, any combination thereof.

[0063] Various types of solenoids and / or combinations of solenoids may be used in fluid distributors, fluid flow control systems, foot support systems, sole structures, and / or footwear articles according to some aspects of the present technology. Some solenoids that may be used in accordance with the present technology include "latching solenoids". A latching solenoid may include two stable states, an open state and a closed state. Such a solenoid can maintain either of these stable states when no power is applied. In the open state, fluid may flow (in either direction) through the solenoid body, for example, between one port and another port. In the closed state, a spring or other biasing means may close either or both of the ports (e.g., by moving a plunger to close the port(s)). In that state, fluid does not flow through the solenoid body.

[0064] In the case of a latching solenoid, power is required to change the solenoid from one state to another (e.g., from the open state to the closed state, or vice versa). Power (e.g., electrical power, battery power, etc.) may initiate the movement of the solenoid's plunger and change the solenoid from one state to another. Typically, a short electrical pulse is applied to move the solenoid's plunger from one position to another. Also, a latching solenoid typically has a "normal state". The "normal state" is the state in which the plunger defaults (e.g., due to a biasing force on the plunger) when the "latch" for holding the plunger in a state is not actuated.

[0065] In the case of a bi-directional latching solenoid (e.g., a 2 / 2 solenoid), the solenoid may be "normally open" (i.e., "NO") where fluid can flow through the solenoid, or "normally closed" (i.e., "NC") where fluid cannot flow through the solenoid. For a normally open solenoid, power is applied with a relatively short pulse to (a) move the plunger from the open configuration to the closed configuration and (b) activate the latching mechanism to hold the solenoid in the closed position without continuously using power. To return this solenoid to the open configuration, power is applied with a relatively short pulse to release the latch or "unlatch" the plunger, and then a biasing system (e.g., a spring) returns the plunger to the open configuration. A "normally closed" solenoid operates in a somewhat opposite manner. For a normally closed solenoid, power is applied with a relatively short pulse to (a) move the plunger from the closed configuration to the open configuration and (b) activate the latching mechanism to hold the solenoid in the open position without continuously using power. To return this solenoid to the closed configuration, power is applied with a relatively short pulse to release the latch or "unlatch" the plunger, and then a biasing system (e.g., a spring) returns the plunger to the closed configuration. In this way, relatively little power is consumed to move the latching solenoid between different configurations and continuous application of power for long periods is not required.

[0066] Similar to a latching solenoid, a non-latching solenoid can also have one "normal" position (e.g., NO or NC) and one or more non-normal positions. Different from a latching solenoid, a non-latching solenoid needs to continuously apply power to maintain the valve in one of two or more states. For example, a normally open ("NO") non-latching solenoid valve needs to continuously apply power to move and maintain the solenoid in the closed state, but when the power is cut off (under the biasing force applied to the plunger), it returns to the open state. Similarly, a normally closed ("NC") non-latching solenoid valve needs to continuously apply power to move and maintain the solenoid in the open state, but when the power is cut off (under the biasing force applied to the plunger), it returns to the closed state. Therefore, during use, it may be advantageous from the perspective of power consumption and / or battery life to select a normally open non-latching solenoid for applications where the valve needs to be closed only for a relatively short period, and / or select a normally closed non-latching solenoid for applications where the valve needs to be open only for a relatively short period.

[0078] Figure 1A is a cross-sectional view of an exemplary footwear article 100 according to some examples of the present technology, showing exemplary components and potential arrangements of these components. As shown in Figure 1A, the footwear article 100 includes an upper 102 and a sole structure 104 engaged with the upper 102. The bottom end portion 102E of the upper 102 is engaged (e.g., sewn) with a strobel member 110 that closes the bottom of the upper 102 (the strobel 110 may be considered part of the upper 102 in at least some examples of the present technology). The upper 102 and / or the strobel member 110 may be attached to the sole structure 104 by any desired method, such as by an adhesive, by a mechanical connector, by stitching, etc., which are conventional methods known and used in the art.

[0079] The upper 102 and the strobel 110 (if present) and / or the sole structure define an internal chamber 100C for receiving the wearer's foot. In this illustrated example, an insole 112 (or an insole member) is included within the internal chamber 100C to support at least a portion of the plantar surface of the wearer's foot. Also, the footwear 100 (e.g., the upper 102) may include any type of closure system (e.g., shoelaces, straps, buckles, etc.) that is generally known and used in the art of footwear.

[0080] The structure of the exemplary footwear 100 shown in Figure 1A includes (a) at least one foot support bladder 200A (one is shown in Figure 1A) for supporting at least a portion of the wearer's foot, and (b) at least one fluid reservoir or fluid tank 400 that may also constitute a fluid-filled bladder. In the example of Figure 1A, the fluid tank 400 includes two fluid chambers 400M and 400L, one on the inside (400M) and one on the outside (400L). These fluid chambers 400M and 400L may be maintained in fluid communication with each other (e.g., at the same pressure), or may be isolated from each other (or may be able to be isolated) (and, e.g., may be at different pressures). Additionally or alternatively, optionally, at least a portion of the fluid tank 400 may be engaged with the upper 102 (e.g., as shown by the dashed line in FIG. 1A).

[0081] FIG. 1A further shows that the sole structure 104 of this embodiment includes a midsole component 600 and an outsole component 300. A foot-actuated pump 500 (e.g., a valve pump) is provided in a space defined between the midsole component 600 and the outsole component 300 (e.g., the compressible valve 504 of the pump 500 may be located between the bottom surface 602S of the midsole component 600 and the upper surface 302S of the outsole component 300). Although not essential, in the illustrated example of FIG. 1A, at least some portions of the fluid tank 400 are also located between the midsole component 600 and the outsole component 300 (and on the opposite side of the pump 500). In use, upon compression of the compressible valve 504 of the pump 500 (e.g., when the wearer takes a step or lands from a jump), fluid moves from inside the valve 504 to the foot support bladder 200A and / or the fluid tank 400. The ways in which fluid can move and the fluid flow paths in embodiments of the present technology will be described in more detail below.

[0082] Figure 1B is a footwear sole structure 104 that includes a fluid dispenser 720 of multiple components (note that for example, component 700 (which may include a fluid distribution manifold) and component 750 (which may include one or more solenoids that control fluid flow paths within the manifold (component 700) that receives fluid)) according to at least some examples of the present technology. Component 700 of the fluid dispenser in this illustrated example includes four connectors that connect to fluid lines 202A, 402, 604, and 606. Fluid line 202A connects between the foot support bladder 200A and the fluid dispenser 720. Fluid line 402 connects between a fluid tank 400 (not shown in Figure 1B but which may be at least located in the heel region of the sole member 104 and / or engage with the upper 102) and the fluid dispenser 720. Fluid line 604 moves fluid from a fluid supply inlet (e.g., from the ambient environment) that may be included in the fluid dispenser 720 (see fluid filter 726F in Figure 1B) to a pump(s) 500 (not shown in Figure 1B but which may be located in the toe region and / or heel region of the sole structure 104). Fluid line 606 returns fluid from the pump 500 to the fluid dispenser 720 for selective distribution, for example, to one or more of other footwear components (e.g., foot support bladder 200A, fluid tank 400, back to the ambient environment, etc.). Another fluid line and connector may be provided to accommodate the movement of fluid to and from a second foot support bladder or a second fluid tank, for example. See Figures 3A - 3E, which are described in more detail below. Fluid lines 202A, 402, 604, and 606 may constitute flexible plastic tubes that engage with connectors provided as part of connector component 700, as will also be described in more detail below. Although other arrangements are possible, in this example, fluid lines 202A, 402, 604, and 606 carry fluid through the footwear structure to a housing 504 located in the outer 300L region of the heel region of the sole structure 104. The housing 504 engages with components 700, 750 of the fluid dispenser 720 to connect the fluid dispenser 720 to the footwear article 100 and / or the sole structure 104.

[0083] Some examples of the present technology include one or more solenoids as part of a fluid dispenser 720 (e.g., included in component 750 of the fluid dispenser of FIG. 1B). Some examples of such solenoid-based systems are described in the applications listed in the section of related application data above. FIGS. 2A-2F schematically illustrate the movement of fluid in various operating states or modes of operation of a foot support system and a footwear article, including (a) two independent foot support bladders 200A, 200B (e.g., heel support bladder and forefoot support bladder, inner bladder and outer bladder, etc.), (b) a pump 500 (e.g., one or more foot-actuated pumps), and (c) a fluid tank 400 (or reservoir) (e.g., one or more fluid-filled bladders included with the upper 102 and / or sole structure 104 of the footwear). Information related to these operating states helps to understand the fluid dispenser 720, foot support system, and components of the footwear article according to the present technology, as will be described in more detail below.

[0084] The exemplary foot support system 1000 of FIGS. 2A-2F includes three solenoids, namely, (a) a first solenoid 4900A including a first port 4910A, a second port 4910B, and a third port 4910C; (b) a second solenoid 4900B including a first port 4912A and a second port 4912B; and (c) a third solenoid 4900C including a first port 4914A and a second port 4914B. The first ports 4910A, 4912A, 4914A of the solenoids 4900A, 4900B, 4900C, respectively, are in fluid communication with a main fluid distribution channel 4920. Thus, the main fluid distribution channel 4920 also fluidly connects the first ports 4910A, 4912A, 4914A of the solenoids 4900A, 4900B, 4900C to each other (under at least some conditions). Additionally, the main fluid distribution channel 4920 is also in fluid communication with a fluid line 606 from a fluid source (such as through a pump 500, a compressor, an external environment 150, a filtered fluid supply inlet 732, etc.). In this example, the first solenoid 4900A is a latching 3-port, 2-state solenoid (3 / 2 solenoid), and the second solenoid 4900B and the third solenoid 4900C are normally closed non-latching solenoids (2 / 2 solenoids), but other specific types of solenoids (such as latching 2 / 2 solenoids) may be used as needed.

[0085] In this illustrated example, (and as will be described in more detail below), the first solenoid 4900A can be switched independently (in either direction) between: (a) a first configuration in which fluid flows through the first solenoid 4900A between the first port 4910A and the second port 4910B; and (b) a second configuration in which fluid flows through the first solenoid 4900A between the first port 4910A and the third port 4910C. Thus, in this example, the first port 4910A and the first solenoid 4900A are always open, and the plunger 4910P moves between: (a) a position where the second port 4910B is open and the third port 4910C is closed; and (b) another position where the second port 4910B is closed and the third port 4910C is open. The first solenoid 4900A in the illustrated example is "normally" biased in the first configuration (using a biasing system (e.g., a spring that applies a force to the plunger 4910P) that closes the third port 4910C). The second solenoid 4900B in this example can be switched independently between an open configuration (in which fluid flows in either direction through the solenoid 4900B between the first port 4912A and the second port 4912B) and a closed configuration (in which fluid does not flow through the solenoid 4900B). Similarly, the third solenoid 4900C in this example can be switched independently between an open configuration (in which fluid flows in either direction through the solenoid 4900C between the first port 4914A and the second port 4914B) and a closed configuration (in which fluid does not flow through the solenoid 4900C). In this foot support system 1000, the simultaneous selective arrangement of: (a) the first solenoid 4900A in one of the first or second configurations; (b) the second solenoid 4900B in one of the open or closed configurations; and (c) the third solenoid 4900C in one of the open or closed configurations selectively arranges this foot support system 1000 in a plurality (e.g., two or more) of operating states. Examples of these operating states will be described in more detail below.

[0086] Figures 2A - 2F are schematic diagrams of a solenoid - based foot support system 1000 disposed in six operating states. Figure 2A shows an operating state where fluid moves from the external environment 150 (e.g., through the filtered fluid inlet 732) and is discharged back into the external environment 150. The fluid flow in this operating state (as well as the fluid flows in the operating states of Figures 2B - 2F) is indicated by the thick arrow - dashed lines in Figure 2A. This operating state can be used as a "stand - by" or "steady - state" operating state to continuously move the pumped (e.g., moved by the foot - actuation pump 500) fluid through the foot support system 1000 and the fluid dispenser 720 even when no pressure change to the foot support bladders 200A, 200B and / or the fluid container 400 is required. In this operating state, the inflow fluid (e.g., air) from the external environment 150 enters from the fluid supply inlet 732 of the fluid dispenser 720, passes through the fluid line 604 (thus exiting the fluid dispenser 720), passes through the pump 500, passes through the fluid line 606, returns to the fluid dispenser 720, passes through the main fluid distribution channel 4920, passes through the first port 4910A of the first solenoid 4900A, passes through the first solenoid 4900A, passes through the second port 4910B of the first solenoid 4900A, enters the fluid discharge fluid channel 716E, and moves to the final destination (in this example, the external environment 150). Further details of the fluid flow in this operating state are described below in conjunction with Figures 4 - 5F.

[0087] Alternatively, in some examples of the present technology, in this operating state, when the fluid is simply about to be returned to and discharged into the external environment 150, instead of continuously moving the fluid through the fluid dispenser 720 at each step, a direct fluid flow path can be provided from the pump 500 to the external environment 150. As another option, the pump 500 can be stopped to achieve this operating state.

[0088] Figure 2B shows an exemplary operating state for adding fluid to the fluid container 400 (e.g., for increasing the fluid volume and / or pressure within the fluid container 400). In this second operating state, the first solenoid 4900A is in a second configuration, and the second solenoid 4900B and the third solenoid 4900C are in a closed configuration. Thus, fluid flows from the air inlet 732 of the fluid dispenser 720, through the fluid line 604 (and thus out of the fluid dispenser 720), through the pump 500, through the fluid line 606, back to the fluid dispenser 720, through the main fluid distribution channel 4920, through the first port 4910A of the first solenoid 4900A, through the first solenoid 4900A, through the third port 4910C of the first solenoid 4900A, through the tank channel 716B, through the fluid line 402, and to the final destination (in this example, the fluid container 400). Further details of the fluid flow in this operating state are described below in conjunction with FIGS. 4, 5A, and 6A-6C.

[0089] In this exemplary foot support system 1000, the fluid container 400 is used to adjust (increase in this example) the fluid pressure in the foot support bladders 200A and 200B. An example of an operating state for increasing the pressure in the first foot support bladder 200A is shown in FIG. 2C. In this third operating state, the first solenoid 4900A is in a second configuration, the second solenoid 4900B is in an open configuration, and the third solenoid 4900C is in a closed configuration. Thus, when the pressure in the fluid container 400 is higher than the pressure in the foot support bladder 200A, fluid flows from the fluid container 400, through the fluid line 402 and the tank channel 716B, through the third port 4910C of the first solenoid 4900A, through the first solenoid 4900A, through the first port 4910A of the first solenoid 4900A, through the main fluid distribution channel 4920, through the first port 4912A of the second solenoid 4900B, through the second solenoid 4900B, through the second port 4912B of the second solenoid 4900B, through the first foot support bladder channel 716C and the fluid line 202A, to the final destination (in this example, the foot support bladder 200A). A check valve (or other suitable valve or switching mechanism) may be provided in the fluid line 606, the pump 500, and / or the fluid line 604, for example, to prevent fluid flow to the fluid line 606, the pump 500, and / or the fluid line 604 and to allow fluid to flow to the second solenoid 4900B. Further details of the fluid flow in this operating state are described below in conjunction with FIGS. 7A-7F.

[0090] Additionally, in this exemplary foot support system 1000, the fluid container 400 is used to adjust (increase in this example) the fluid pressure in the foot support bladder 200B. An example of an operating state for increasing the pressure in the second foot support bladder 200B is shown in FIG. 2D. In this fourth operating state, the first solenoid 4900A is in a second configuration, the second solenoid 4900B is in a closed configuration, and the third solenoid 4900C is in an open configuration. Thus, when the pressure in the fluid container 400 is higher than the pressure in the foot support bladder 200A, fluid flows from the fluid container 400 through the fluid line 402 and the tank channel 716B, through the third port 4910C of the first solenoid 4900A, through the first solenoid 4900A, through the first port 4910A of the first solenoid 4900A, through the main fluid distribution channel 4920, through the first port 4914A of the third solenoid 4900C, through the third solenoid 4900C, through the second port 4914B of the third solenoid 4900C, through the second foot support bladder channel 716D and the fluid line 202B to the final destination (in this example, the foot support bladder 200B). A check valve (or other suitable valve or switching mechanism) may be provided in the fluid line 606, the pump 500, and / or the fluid line 604, for example, to prevent fluid flow to the fluid line 606, the pump 500, and / or the fluid line 604 and to allow fluid to flow to the third solenoid 4900C. Further details of the fluid flow in this operating state are described below in conjunction with FIGS. 8A - 8F.

[0091] In some cases, it may be desirable to remove fluid from the foot support bladder 200A in order to reduce the pressure in the foot support bladder 200A (e.g., to provide a softer feel or for less strenuous activities such as walking or for casual wear). FIG. 2E shows an example of this operating state. In this fifth operating state, the first solenoid 4900A is in the first configuration, the second solenoid 4900B is in the open configuration, and the third solenoid 4900C is in the closed configuration. Thus, fluid flows from the foot support bladder 200A, through the fluid line 202A and the first foot support bladder channel 716C, through the second port 4912B of the second solenoid 4900B, through the second solenoid 4900B, through the first port 4912A of the second solenoid 4900B, through the main fluid distribution channel 4920, through the first port 4910A of the first solenoid 4900A, through the first solenoid 4900A, through the second port 4910B of the first solenoid 4900A, through the fluid discharge channel 716E, to the final destination (in this example, the external environment 150). A check valve (or other suitable valve or switching mechanism) may be provided in the fluid line 606, the pump 500, and / or the fluid line 604, for example, to prevent fluid flow to the fluid line 606, the pump 500, and / or the fluid line 604 and to allow fluid to flow to the first solenoid 4900A. Further details of the fluid flow in this operating state are described below in conjunction with FIGS. 9A - 9H.

[0092] Also, in some cases, it may be desirable to remove fluid from the foot support bladder 200B in order to reduce the pressure in the foot support bladder 200B (e.g., to provide a softer feel or for less strenuous activities such as walking or for casual wear). FIG. 2F shows an example of this operating state. In this sixth operating state, the first solenoid 4900A is in the first configuration, the second solenoid 4900B is in the closed configuration, and the third solenoid 4900C is in the open configuration. Thus, fluid flows from the foot support bladder 200B, through the fluid line 202B and the second foot support bladder channel 716D, through the second port 4914B of the third solenoid 4900C, through the third solenoid 4900C, through the first port 4914A of the third solenoid 4900C, through the main fluid distribution channel 4920, through the first port 4910A of the first solenoid 4900A, through the first solenoid 4900A, through the second port 4910B of the first solenoid 4900A, through the fluid discharge channel 716E, to the final destination (in this example, the external environment 150). A check valve (or other suitable valve or switching mechanism) may be provided in the fluid line 606, the pump 500, and / or the fluid line 604, for example, to prevent fluid flow to the fluid line 606, the pump 500, and / or the fluid line 604 and to allow fluid to flow to the first solenoid 4900A. Further details of the fluid flow in this operating state are described below in conjunction with FIGS. 10A - 10H.

[0093] The exemplary foot support system 1000 of FIGS. 2A-2F does not have an operating state in which fluid moves from the external environment 150 to the fluid dispenser 720 and is then directly transferred to the foot support bladders 200A, 200B. Rather, in the foot support system 1000 of FIGS. 2A-2F, fluid pressure increases in the foot support bladders 200A, 200B only by fluid transfer from the fluid container 400 to the foot support bladders 200A, 200B (as shown by the operating states of FIGS. 2C and 2D). Further, the exemplary foot support system 1000 of FIGS. 2A-2F does not have an operating state in which fluid moves directly from the fluid container 400 to the external environment 150 (e.g., to contract the container 400). Rather, contraction of the container 400 can be achieved, for example, by moving fluid from the container to one of the foot support bladders 200A, 200B (FIGS. 2C and 2D), and then moving the fluid from the bladders 200A, 200B to the external environment 150 (FIGS. 2E and 2F). If necessary or desired, the fluid container 400 may include a check valve or pressure relief valve ("PRV") that vents to the external environment 150 to prevent overpressurization of the fluid container 400 (rather than having excess fluid from the container 400 pass through the fluid dispenser 720 to reduce the pressure within the fluid container 400). Additionally or alternatively, if the fluid pressure from the fluid source (e.g., the fluid pressure generated by one or more foot actuation pumps 500) is insufficient or falls below the fluid pressure in the open fluid path to the fluid container 400, fluid is not transferred from the fluid source to the fluid container 400. Further additionally or alternatively, other pressure relief valves and / or fluid paths may be provided at one or more locations of the overall fluid dispenser 720, fluid flow control system, foot support system 1000, sole structure 104, and / or footwear article 100 to prevent overpressurization of any part of the system (e.g., relieve pressure from the fluid discharged by the pump(s) 500 if there is nowhere else for the fluid to go without causing damage).

[0094] An additional solenoid (e.g., a 2 / 2 non-latching solenoid) and appropriate structure and operating conditions are shown in FIGS. 2A-2F and may be provided for any additional foot support bladder beyond the bladder 200A, 200B discussed above.

[0095] With this background information in mind, FIGS. 3A-3E provide various views of the components that make up the fluid dispenser 720 according to some examples of the present technology, and FIGS. 4-10H provide various views of the fluid flow paths through these components to provide the various operating conditions described above in conjunction with FIGS. 2A-2F. This fluid flow path is shown by thick dashed lines in FIGS. 4-10H.

[0096] FIG. 3A is a perspective view of a first component 700A (also referred to herein as the "first body portion") of a fluid dispenser 720 according to some examples of the present technology. Also note FIG. 1B. This first component 700A may be considered a manifold or at least a portion of a manifold. This exemplary first component 700A includes a first side 710 having at least two solenoid mounts, three solenoid mounts in this illustrated example, a first solenoid mount 710A, a second solenoid mount 710B, and a third solenoid mount 710C. The solenoid mounts 710A, 710B, and 710C each include a connector or other suitable structure for engaging and attaching a solenoid 4900A, 4900B, 4900C in a particular operating manner (e.g., a sealed engagement).

[0097] The second side 712 of the first component 700A includes a first surface 712S that defines at least some portions of two or more fluid transfer channels of the fluid dispenser 720. In the exemplary structure shown in FIG. 3A, the surface 712S includes: (i) a first open channel 714A that defines at least a portion of the main fluid distribution channel 4920 of the fluid dispenser 720 at the first surface 712S (the channel 714A has an open top at the surface 712S); (ii) a second open channel 714B that defines at least a portion of the tank channel 716B of the fluid dispenser 720 at the first surface 712S (the channel 714B has an open top at the surface 712S); (iii) a third open channel 714C that defines at least a portion of the first foot support bladder channel 716C of the fluid dispenser 720 at the first surface 712S (the channel 714C has an open top at the surface 712S); (iv) a fourth open channel 714D that defines at least a portion of the second foot support bladder channel 716D of the fluid dispenser 720 at the first surface 712S (the channel 714D has an open top at the surface 712S); and (v) a fifth open channel 714E that defines at least a portion of the fluid discharge channel 716E of the fluid dispenser 720 at the first surface 712S (the channel 714E has an open top at the surface 712S). While other arrangements are possible, in the example of FIG. 3A, the first side 710 (having solenoid mounts 710A - 710C) of the component 700A is adjacent to the second side 712 (e.g., the sides 710, 712 extend at approximately 90 degrees to each other).

[0098] FIG. 3B is a perspective view of a second component 700B (also referred to herein as the “second body portion”) of a fluid dispenser 720 that is intended to engage at least a first surface 712S of a first component 700A. This second component 700B (second body portion) includes a major surface 722S that faces directly and engages the surface 712S so as to close one or more of the open channels of the first component 700A. Although not a requirement, in this illustrated example, the major surface 722S of the second component 700B includes one or more grooves that correspond (e.g., in size and shape) to one or more of the open channels at the first surface 712S of the first component 700A. More specifically, in this example, the major surface 722S of the second component 700B includes: (i) a first recess 724A sized and shaped to close a first open channel 714A (which may also constitute an open channel) to provide a major fluid distribution channel 4920 of the fluid dispenser 720; (ii) a second recess 724B sized and shaped to close a second open channel 714B to provide a tank channel 716B of the fluid dispenser 720; (iii) a third recess 724C sized and shaped to close a third open channel 714C to provide a first foot support bladder channel 716C of the fluid dispenser 720; (iv) a fourth recess 724D sized and shaped to close a fourth open channel 714D to provide a second foot support bladder channel 716D of the fluid dispenser 720; and (v) a fifth recess 724E sized and shaped to close a fifth open channel 714E to provide a fluid discharge channel 716E of the fluid dispenser 720.The first component 700A and the second component 700B may be sealingly engaged together so as to seal and form, for example, the main fluid distribution channel 4920, the tank channel 716B, the first foot support bladder channel 716C, the second foot support bladder channel 716D, and the fluid discharge channel 716E from their corresponding open channels 714A - 714E and recesses 724A - 724E. If necessary, a gasket or a sealing ring may be provided to help ensure a fluid tight seal. Additionally or alternatively, one or more of the recesses 724A - 724E may be omitted and the corresponding open channel(s) 714A - 714E of the first component 700A may be closed and / or sealed with the major surface 722S of the second component 700B (e.g., by the flat major surface 722S).

[0099] Figures 3C and 3D show the surface 726S of the second component 700B facing the surface 722S. As shown, the surface 726S includes one or more tube connectors that carry fluid into and out of the fluid dispenser 720. The example of FIG. 3C includes five tube connectors 730A - 730E. The first tube connector 730A receives the inflow fluid from the external environment 150 (via the fluid supply inlet 732) and moves the inflow fluid to the pump 500 (e.g., a foot - actuated pump) via the fluid line 604. The second tube connector 730B receives the fluid (pressurized fluid) from the pump 500 via the fluid line 606 and moves this fluid to the fluid dispenser 720. The third tube connector 730C is connected to the fluid line 402, thereby moving fluid in both directions between the fluid tank 400 and the fluid dispenser 720. The fourth tube connector 730D is connected to the fluid line 202A, thereby moving fluid in both directions between the first foot support bladder 200A and the fluid dispenser 720. The fifth tube connector 730E is connected to the fluid line 202B, thereby moving fluid in both directions between the second foot support bladder 200B and the fluid dispenser 720. FIG. 3C shows the step of connecting the external fluid lines 604, 606, 402, 202A, 202B (e.g., flexible plastic tubes) to their respective connectors 730A - 730E. The fluid lines 604, 606, 402, 202A, 202B may be permanently fixed (e.g., with an adhesive) to their respective connectors 730A - 730E or may be releasably connected (e.g., via a friction fit, via a clamp or other mechanical connector, etc.).

[0100] FIG. 3D further shows that the surface 726S of the second component 700B is formed to include an internal chamber 726. The chamber 726 receives inflowing fluid from the external environment 150 through a filter 726F (see FIG. 3C). The filter 726F closes the chamber 726 and filters the inflowing fluid, after which the inflowing fluid can be introduced into the fluid distributor 720 and / or the foot support system. The chamber 726 includes filtered fluid for introduction into the foot support system via a fluid supply inlet 732 that opens into the chamber 726 and into the first tube connector 730A. The port 748B shown in FIG. 3D opens into the fluid discharge channel 716E.

[0101] Further details regarding the various fluid channels of the fluid dispenser 720 of this example are shown below. The first open channel 714A (and the main fluid distribution channel 4920 partially formed by each of the first open channel 714A and the first recess 724A) includes (a) a first opening or port 740A in fluid communication with the first solenoid mount 710A (and thus the first solenoid 4900A), (b) a second opening or port 740B in fluid communication with the second solenoid mount 710B (and thus the second solenoid 4900B), (c) a third opening or port 740C in fluid communication with the third solenoid mount 710C (and thus the third solenoid 4900C), and (d) a fourth opening or port 740D in fluid communication with a connector 730B that receives inflowing fluid from the pump 500 via the fluid line 606. As shown in FIG. 3A, on the first surface 712S, the main fluid distribution channel 4920 and its first open channel 714A include (a) a baseline 740BL, (b) a first arm 740FA extending from the baseline 740BL toward the first solenoid mount 710A (the first arm 740FA includes the first opening 740A and the fourth opening 740D), (c) a second arm 740SA extending from the baseline 740BL toward the second solenoid mount 710B (the second arm 740SA includes the second opening 740B), and (d) a third arm 740TA extending from the baseline 740BL toward the third solenoid mount 710C (the third arm 740TA includes the third opening 740C). The first recess 724A within the second component 700B that forms another portion of the main fluid distribution channel 4920 may have corresponding recesses having corresponding baselines and a plurality of arm shapes, as shown in FIG. 3B.

[0102] The second open channel 714B (and thus the tank channel 716B partially formed by each of the second open channel 714B and the second recess 724B) includes (a) a first opening or port 742A in fluid communication with the first solenoid mount 710A (and thus the first solenoid 4900A), and (b) a second opening or port 742B in fluid communication with a connector 730C that transfers fluid to and from the fluid tank 400 via the fluid line 402. The first and second openings or ports 742A, 742B are not shown in the figure of FIG. 3A, but these components can be seen in other figures, for example, by referring to FIGS. 6B, 6C, 7A, 7B, 8A, and 8B. As shown in FIG. 3A, on the first surface 712S, the second open channel 714B of the tank channel 716B is located between the first arm 740FA and the second arm 740SA of the main fluid distribution channel 4920 and its first open channel 714A. The second open channel 714B (and thus the tank channel 716B) is somewhat boomerang-shaped on the first surface 712S, for example, with the two arms arranged at an angle within the range of 100 degrees to 170 degrees. The second recess 724B within the second component 700B that forms another part of the tank channel 716B may have corresponding two-arm shapes and angular shapes as shown in FIG. 3B.

[0103] The third release channel 714C (and thus the first foot support channel 716C partially formed by each of the third release channel 714C and the third recess 724C) includes (a) a first opening or port 744A in fluid communication with the second solenoid mount 710B (and thus the second solenoid 4900B), and (b) a second opening or port 744B in fluid communication with a connector 730D that transfers fluid to and from the first foot support bladder 200A via the fluid line 202A. The first and second openings or ports 744A, 744B are not shown in the figure of FIG. 3A, but these components can be seen in other figures, for example, by referring to FIGS. 7D - 7F and FIGS. 9A - 9C. As shown in FIG. 3A, on the first surface 712S, the third release channel 714C of the first foot support channel 716C is located between the first arm 740FA and the second arm 740SA of the main fluid distribution channel 4920 and its first release channel 714A (actually, between the second release channel 714B of the main fluid distribution channel 4920, the second arm 740SA, and its first release channel 714A). The third release channel 714C (and thus the first foot support channel 716C) is linear or elliptical in shape on the first surface 712S. The third recess 724C within the second component 700B that forms another portion of the first foot support channel 716C may have a corresponding linear or elliptical shape as shown in FIG. 3B.

[0104] The fourth release channel 714D (and thus the second foot support channel 716D partially formed by each of the fourth release channel 714D and the fourth recess 724D) includes (a) a first opening or port 746A in fluid communication with the third solenoid mount 710C (and thus the third solenoid 4900C), and (b) a second opening or port 746B in fluid communication with a connector 730E that transfers fluid to and from the second foot support bladder 200B via the fluid line 202B. The first and second openings or ports 746A, 746B are not shown in the figure of FIG. 3A, but these components can be seen in other figures, for example, with reference to FIGS. 8E-8F and FIGS. 10A-10C. As shown in FIG. 3A, on the first surface 712S, the fourth release channel 714D of the second foot support channel 716D is located between the first arm 740FA and the third arm 740TA of the main fluid distribution channel 4920 and its first release channel 714A.

[0105] The fourth open channel 714D (and thus the second foot support channel 716D) is linear or oval in shape on the first surface 712S. The fourth recess 724D within the second component 700B that forms another portion of the second foot support channel 716D may have a corresponding linear or oval shape, as shown in FIG. 3B. The fifth open channel 714E (and thus the fluid discharge channel 716E partially formed by each of the fifth open channel 714E and the fifth recess 724E) includes (a) a first opening or port 748A in fluid communication with the first solenoid mount 710A (and thus the first solenoid 4900A), and (b) a second opening or port 748B in fluid communication with the ambient environment 150, for example, via the internal chamber 726 shown in FIG. 3D. As shown in FIG. 3A, on the first surface 712S, the fifth open channel 714E of the fluid discharge channel 716E is located between (in fact, between the second open channel 714B of the main fluid distribution channel 4920, the first arm 740FA, and its first open channel 714A) the first arm 740FA and the second arm 740SA of the main fluid distribution channel 4920 and its first open channel 714A. The fifth open channel 714E (and thus the fluid discharge channel 716E) has a curved shape (e.g., boomerang shape) on the first surface 712S. The fifth recess 724E within the second component 700B that forms another portion of the fluid discharge channel 716E may have a corresponding curved shape, as shown in FIG. 3B.

[0106] Figure 3E further shows the connection of solenoids 4900A, 4900B, and 4900C to their corresponding solenoid mounts 710A, 710B, and 710C by connection arrows 750A, 750B, and 750C. Any desired type of connection and connection structure may be provided for connecting solenoids 4900A, 4900B, and 4900C to their corresponding solenoid mounts 710A, 710B, and 710C (e.g., screw connection, retaining ring, 1 / 4 turn lock structure, etc.). Solenoids 4900A, 4900B, and 4900C may be attached to their corresponding solenoid mounts 710A, 710B, and 710C before or after the second body portion 700B is engaged with the first body portion 700A and / or before or after fluid tubes 604, 606, 402, 202A, 202B are engaged with their respective connectors 730A - 730E. Optionally, one or more of solenoids 4900A, 4900B, and 4900C may be at least partially contained within a housing such as component 750 of fluid dispenser 720 shown in FIG. 1B. Although other arrangements are possible, solenoid 4900A may be a 3 / 2 latching solenoid, and solenoids 4900B and 4900C may be normally closed ( "NC") 2 / 2 non - latching solenoids.

[0107] FIG. 4 shows a fluid flow path that enters the fluid dispenser 720 from the external environment 150 through the fluid dispenser 720, reaches the pump 500, and returns to the fluid dispenser 720 (for further distribution, for example, described in more detail below). To enable visualization of the internal chamber 726, the filter 726F is not shown in FIG. 4 (see, however, FIG. 3C). Fluid (e.g., air) from the external environment 150 passes through the filter 726F and enters the internal chamber 726. The internal chamber 726 includes a fluid supply inlet 732 that is in fluid communication with (and supplies fluid to) the first connector 730A. As shown in FIG. 3C, the fluid transfer line 604 is connected to the first connector 730A, and the fluid transfer line 604 transfers fluid to the inlet of the pump 500 (e.g., a foot-actuated pump provided in the sole structure - see FIG. 1A). When pumped by the pump, the pressurized fluid (e.g., air) exits the outlet of the pump 500, flows into the fluid transfer line 606 (see FIG. 3C), and returns to the fluid dispenser 720 at the second connector 730B via the fluid transfer line 606. The fluid moves from the connector 730B through the fluid dispenser 720 to different potential destinations (note the operating states described in conjunction with FIGS. 2A - 2F). Examples of these fluid flow paths through the fluid dispenser 720 are described in more detail below in conjunction with FIGS. 5A - 10H.

[0108] FIGS. 5A - 5F show the flow of fluid through the fluid dispenser 720 in the operating state shown in FIG. 2A. FIG. 2A shows an operating state in which fluid moves from the external environment 150 to the fluid dispenser 720 and is discharged back to the external environment 150. This operating state may be used as a "standby" or "steady state" operating state to continue to move the pumped fluid (e.g., from the foot-actuated pump 500) through the fluid dispenser 720 even when no pressure change to the foot support bladders 200A, 200B and / or the fluid container 400 is required.

[0109] In this operating state, the first fluid enters the fluid dispenser through the fluid supply inlet 732, the first connector 730A, the fluid line 604, the pump 500, the fluid line 606, and the second connector 730B in the manner described above in conjunction with FIG. 4. FIG. 5A is a partial cross-sectional view of the fluid dispenser 720 showing the fluid flow path through the second connector 730B to the main fluid distribution channel 4920 (formed in this illustrated example by the first open channel 714A of the first part 700A of the dispenser and the first recess 724A of the second part 700B of the dispenser). The fluid flow direction and passage are indicated by thick dashed arrows in FIG. 5A (and FIGS. 5B - 10H).

[0110] FIGS. 5B and 5C are further cross-sectional views showing the continuous fluid flow direction and passage in this operating state. As shown in these figures, the fluid flows from the main fluid distribution channel 4920 through the opening 740A of the main fluid distribution channel 4920 and the first port 4910A of the first solenoid 4900 into the interior of the first solenoid 4900A. In this configuration and operating state, the first solenoid 4900 is in the "unlatched" state. The fluid exits the interior of the first solenoid 4900A through the small hole 4940 of the valve bobbin 4942. See FIG. 5D. The perforated spacer 900 is attached between the O-rings 902 that seal the first solenoid 4900 at the solenoid mount 710A. See FIGS. 5C and 5E. The fluid exiting the hole 4940 of the bobbin 4942 moves through (and / or around) the perforated spacer 900, exits the first solenoid 4900A at the solenoid mount 710A (via port 4910B), and is discharged through the opening 748A into the fluid discharge channel 716E. As described above, the fluid discharge channel 716E in this example is formed from the fifth open channel 714E of the first part 700A of the dispenser and the fifth recess 724E of the second part 700B of the dispenser.

[0111] Upon entering the fluid discharge channel 716E, the fluid moves within the fluid discharge channel 716E and returns to the internal chamber 726 through the opening 748B. Refer to FIG. 5F. From there, the fluid can be discharged to the external environment 150 (e.g., through the filter 726F) (refer to the fluid flow line 904) or drawn back to the first connector 730A, where it can be sent to the pump 500 and returned to the fluid dispenser 720 again (refer to the fluid flow line 906).

[0112] FIGS. 6A - 6C show some portions of the fluid flow path through the fluid dispenser 720 in the operating state of FIG. 2B above, i.e., when the fluid moves from the external environment to the fluid tank 400. As an initial step in this operating state, the fluid moves from the external environment 150 through the fluid supply inlet 732 of the fluid dispenser 720 to the pump 500 and back to the fluid dispenser 720 as described above in conjunction with FIG. 4. Next, as described above in conjunction with FIGS. 5A - 5B, the fluid moves from the second connector 730B (which receives pressurized fluid from the pump 500) through the main fluid distribution line 4920 to the first solenoid 4900A. By that flow, the fluid is carried to the point shown in FIG. 6A. In this operating state, the first solenoid 4900A is in the latched state, which enables the fluid to flow from the solenoid port 4910A to the port 4910C. Refer to FIG. 6B. The port 4910C of the solenoid 4900A opens into the tank channel 716B through the opening 742A (the tank channel 716B is formed in this exemplary structure by the second open channel 714B within the first component 700A of the fluid dispenser 720 and the second recess 724B within the second component 700B of the fluid dispenser 720). Upon entering the tank channel 716B, as shown in FIG. 6B, the fluid moves to the connector 730C through the opening 742B, moves from the third connector 730C to the fluid line 402, and then moves to the tank 400 through the fluid line 402.

[0113] Figures 7A - 7F show the flow of fluid from tank 400 through fluid dispenser 720 in the operating state shown in FIG. 2C to the first foot support bladder 200A. The first steps shown in FIGS. 7A and 7B are somewhat opposite to the fluid flow described above in conjunction with FIGS. 6B and 6C. In this operating state, the fluid begins within tank 400, moves via fluid line 402 to the third connector 730C, and then moves via opening 742B to tank channel 716B. Refer to FIG. 7A. Upon entering tank channel 716B, as shown in FIG. 7B, the fluid enters the first solenoid 4900A (in the latched configuration) through opening 742A and port 4910C, enters port 4910A through the first solenoid 4900A, and enters the main fluid distribution channel 4920 via opening 740A. FIG. 7C further shows the movement of fluid through port 4910A and into the main fluid distribution channel 4920 through the first solenoid 4900A. Upon entering the main fluid distribution channel 4920, the fluid moves through opening 740B and solenoid port 4912A to the second solenoid 4900B. The second solenoid 4900B is in the "open configuration" in this operating state (the third solenoid 4900C is in the "closed configuration"). Since the second solenoid 4900B is open, the fluid passes through the second solenoid 4900B and enters the first foot support bladder channel 716C (formed by the third open channel 714C within the first component 700A of fluid dispenser 720 and the third recess 724C within the second component 700B of fluid dispenser 720) via solenoid port 4912B and opening 744A. Refer to FIGS. 7D and 7E. Upon entering the first foot support bladder channel 716C, the fluid passes through opening 744B to the fourth connector 730D, enters the first foot support fluid line 202A, and then enters the first foot support bladder 200A. Refer also to FIG. 7F.

[0114] Figures 8A - 8F show the flow of fluid through the fluid dispenser 720 in the operating state shown in FIG. 2D from the tank 400 to the second foot support bladder 200B. The first steps shown in FIGS. 8A and 8B are the same as those shown in FIGS. 7A and 7B (slightly opposite to the fluid flow described above in conjunction with FIGS. 6B and 6C). In this operating state, the fluid begins in the tank 400, moves through the fluid line 402 to the third connector 730C, and then moves to the tank channel 716B through the opening 742B. See FIG. 8A. Upon entering the tank channel 716B, as shown in FIG. 8B, the fluid enters the first solenoid 4900A (in the latched configuration) through the opening 742A and port 4910C, enters port 4910A through the first solenoid 4900A, and enters the main fluid distribution channel 4920 through the opening 740A. FIG. 8C further shows the movement of the fluid through the first solenoid 4900A to port 4910A and then to the main fluid distribution channel 4920. Upon entering the main fluid distribution channel 4920, the fluid moves through the opening 740C and solenoid port 4914A to the third solenoid 4900C. The third solenoid 4900C is in the "open configuration" in this operating state (the second solenoid 4900B is in the "closed configuration"). Since the third solenoid 4900C is open, the fluid passes through the third solenoid 4900C and enters the second foot support bladder channel 716D (formed by the fourth open channel 714D in the first component 700A of the fluid dispenser 720 and the fourth recess 724D in the second component 700B of the fluid dispenser 720 in this example) through the solenoid port 4914B and opening 746A. See FIGS. 8D and 8E. Upon entering the second foot support bladder channel 716D, the fluid passes through the opening 746B to the fifth connector 730E, enters the second foot support fluid line 202B, and then enters the second foot support bladder 200B. See also FIG. 8F.

[0115] Figures 9A - 9H show the flow of fluid from the first foot support bladder 200A to the external environment 150 through the fluid dispenser 720 in the operating state shown in FIG. 2E. The first step is somewhat opposite to the steps described above in conjunction with FIGS. 7C - 7F. First, the fluid flows from the first foot support bladder 200A through the fluid line 202A and enters the fourth connector 730D of the fluid dispenser 720. The fourth connector 730D opens into the first foot support bladder channel 716C through the opening 744B. The fluid flows through the first foot support bladder channel 716C and flows to the opening 744A and port 4912B of the second solenoid 4900B. The second solenoid 4900B is in an open configuration (the third solenoid 4900C is in a closed configuration). Thus, as shown in FIGS. 9B and 9C, the fluid flows through the second solenoid 4900B to the other port 4912A, and the port 4912A is open at the opening 740B, moving the fluid to the main fluid distribution channel 4920 of the fluid dispenser 720. Upon entering the main fluid distribution channel 4920, the fluid moves through the opening 740A of the first solenoid 4900A and the first port 4910A. The first solenoid 4900A is in a non - latched state in this configuration, thus allowing the fluid to flow from port 4910A to port 4910B. Thus, the fluid moves through the first solenoid 4900A as shown in FIGS. 9D and 9E. The fluid exits the interior of the first solenoid 4900A through the small hole 4940 of the valve bobbin 4942. See FIG. 9F. As described above in conjunction with FIGS. 5A - 5F, the perforated spacer 900 is attached between the O - rings 902 that seal the first solenoid 4900 at the solenoid mount 710A. The fluid exiting the hole 4940 of the bobbin 4942 moves through (and / or around) the perforated spacer 900 and exits the first solenoid 4900A at the solenoid mount 710A (through port 4910B) and is discharged through the opening 748A to the fluid discharge channel 716E. See also FIG. 9G. Upon entering the fluid discharge channel 716E, the fluid moves within the fluid discharge channel 716E and returns to the internal chamber 726 through the opening 748B. See FIG. 9H.From there, the fluid can either be released to the external environment 150 (e.g., through filter 726F, see fluid flow line 904) or drawn back to the first connector 730A, where it can be sent to pump 500 and returned to fluid dispenser 720 again (see fluid flow line 906).

[0116] Figures 10A - 10H show the flow of fluid from the second foot support bladder 200B through the fluid dispenser 720 in the operating state shown in Figure 2F to the external environment 150. As a first step, the fluid flows from the second foot support bladder 200B through the fluid line 202B and enters the fifth connector 730E of the fluid dispenser 720. The fifth connector 730E opens into the second foot support bladder channel 716D via the opening 746B. The fluid flows through the second foot support bladder channel 716D to the opening 746A and port 4914B of the third solenoid 4900C. The third solenoid 4900C is in an open configuration (the second solenoid 4900B is in a closed configuration). Thus, as shown in Figures 10B and 10C, the fluid flows through the third solenoid 4900C to the other port 4914A, and the port 4914A is open at the opening 740C, moving the fluid to the main fluid distribution channel 4920 of the fluid dispenser 720. Upon entering the main fluid distribution channel 4920, the fluid moves through the opening 740A of the first solenoid 4900A and the first port 4910A. The first solenoid 4900A is in an unlatched state in this configuration, thus allowing the fluid to flow from port 4910A to port 4910B. Thus, the fluid moves through the first solenoid 4900A as shown in Figures 10D and 10E. The fluid exits the interior of the first solenoid 4900A through the small hole 4940 of the valve bobbin 4942. See Figure 10F. As described above in conjunction with Figures 5A - 5F, the perforated spacer 900 is attached between the O - rings 902 that seal the first solenoid 4900 at the solenoid mount 710A. The fluid exiting the hole 4940 of the bobbin 4942 moves through (and / or around) the perforated spacer 900, exits the first solenoid 4900A at the solenoid mount 710A (via port 4910B), and is discharged through the opening 748A to the fluid discharge channel 716E. See also Figure 10G. Upon entering the fluid discharge channel 716E, the fluid moves within the fluid discharge channel 716E and returns to the internal chamber 726 through the opening 748B. See Figure 10H.From there, the fluid can either be released to the external environment 150 (e.g., through filter 726F, see fluid flow line 904), or drawn back to the first connector 730A, where it can be sent to pump 500 and returned to fluid dispenser 720 again (see fluid flow line 906).

[0117] More or fewer foot support bladders may be included in an example of the present technology, such as in a foot support system, a sole structure, and / or a footwear article, by adding or removing corresponding foot support channels (such as channels 716C, 716D) in fluid dispenser 720, by adding or removing corresponding connectors (such as 730D, 730E) in fluid dispenser 720, by adding or removing corresponding fluid lines (such as 202A, 202B), by adding or removing corresponding solenoids 4900B, 4900C, etc. More or fewer fluid containers or tanks (such as tank 400) may be included in an example of the present technology, such as in a foot support system, a sole structure, and / or a footwear article, by adding or removing corresponding tank channels (such as channel 716B) in fluid dispenser 720, by adding or removing corresponding connectors (such as 730C) in fluid dispenser 720, by adding or removing corresponding tank fluid lines (such as 402), etc.

[0118] Also, other operating states may be provided, such as the operating state from the tank to the surroundings (tank "shrink" mode). Such an operating state includes the movement of fluid from the tank 400, through the fluid line 402 to the connector 730C, through the tank channel 716B in the fluid dispenser 720 (similar to FIGS. 7A-7B), through the first solenoid 4900A (from port 4910C to port 4910B), out of the first solenoid 4900A (e.g., through the bobbin 4942, perforated spacer 900, etc.), to the fluid discharge channel 716E of the fluid dispenser 720, and then to the surrounding environment (e.g., as described in conjunction with FIGS. 9E-9H and FIGS. 10E-10H). In this potential operating state, the first solenoid 4900A must be arranged in a configuration where ports 4910B and 4910C are open (e.g., port 4900A is closed (or other appropriate fluid lines and / or fluid routing must be provided)). As other potential operating states, (a) two or more foot support bladders (e.g., 200A, 200B) may be inflated simultaneously (e.g., by both the second solenoid 4900B and the third solenoid 4900C opening simultaneously, as in the operating states shown in FIGS. 2C and 2D, and when fluid moves from the tank 400 to the foot support bladders 200A, 200B), and / or (b) two or more foot support bladders (e.g., 200A, 200B) may be deflated simultaneously (e.g., by both the second solenoid 4900B and the third solenoid 4900C opening simultaneously, as in the operating states shown in FIGS. 2E and 2F, and when fluid moves from the foot support bladders 200A, 200B to the surrounding environment 150). As a further additional or alternative operating state, the fluid can move from the pump(s) 500, and for example, while the pump(s) 500 is moving fluid from the fluid supply inlet 732 into the pressurized fluid line 606, one or more foot support bladders (e.g., 200A, 200B) can be directly inflated by closing the solenoid 4900A and opening the solenoid(s) 4900B and / or 4900C.

[0119] Aspects of the present technology, such as the arrangement of channels 4920, 716B, 716C, 716D, and 716E within fluid dispenser 720 and the structure of dispenser 720, may be useful for creating an easily attachable and / or small and / or lightweight system for changing the foot support pressure of footwear and foot receiving devices that include one or more inflatable foot support bladders.
