The present disclosure relates to shoe pads and more specifically to a system and method for adhering a customized sole-shaped pad to the sole of a shoe to prevent floor contamination.
Doormats serve to remove soil and contaminants from shoes as people enter homes, offices, or specific rooms. Typically a person will stand on the doormat or will move their feet over the doormat to brush dirt off. Standard doormats and floormats offer a time-efficient solution for removing some of the dirt and other contaminants off of shoes, but often fail to prevent tracking of dirt into the home or office. Other solutions for preventing the unintended distribution of dirt include tacky mats and shoe envelopment. For example, in the case of professional basketball, the players step onto a tacky mat specifically designed to remove particles which may result in a player sliding or slipping on the basketball court. Clean room solutions prevent any contamination or tracking of dirt by enveloping the shoe in a protective galosh or “bootie.” Covering of the shoe, while appropriate for certain circumstances, is an undesirable solution for most homes and offices.
Additional features and advantages of the disclosure will be set forth in the description which follows, and in part will be obvious from the description, or can be learned by practice of the herein disclosed principles. The features and advantages of the disclosure can be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. These and other features of the disclosure will become more fully apparent from the following description and appended claims, or can be learned by the practice of the principles set forth herein.
Disclosed are systems, methods, and non-transitory computer-readable storage media for adhesive application of a customized sole-shaped pad to a shoe. As an example, a system configured per this disclosure can be an advanced doormat which receives an input signal indicating user readiness to adhere shoe pads to the soles of the user's shoes. The input signal can be obtained via a voice command, a motion sensor (including laser, infrared, radio frequency, ultrasound, and other formats), a spoken command, a manual button on the system, or other appropriate input means. The system moves an adhesive film, or material, which can have micro-perforations into position over a set of pins. The user steps onto the adhesive film. As the user steps onto the adhesive film, the portion of the adhesive film directly below the sole of the shoe adheres to the shoe. The adhesive film can have a balance of physical characteristics where the force required to vertically shear the film is greater than the force to perform lateral tearing. The pins directly below the sole of the shoe lower or compress due to the weight of the user and the shoe.
The resulting height differential between the portion adhered to the sole of the shoe (e.g., lowered due to the weight of the user or raised via springs and/or motorization) and the remaining adhesive film (at the original height, supported by the remaining pins) causes a shearing of the micro-perforations in a shape corresponding to the contour of the user's shoe. As the user steps off of the doormat, i.e., steps off of the adhesive film, the sheared portion remains adhered to the shoe, preventing tracking of future dirt or other contaminants. After the user steps off of the advanced doormat, what remains is a section of adhesive film with two sole-shaped holes corresponding to the sheared portions. The system collects the remainder of the adhesive film using a roller system or some other mechanism which causes a rotation or movement of the adhesive film such that a fresh portion of the adhesive film is positioned over the pins in preparation for another user stepping onto the doormat. The user can then walk away with the soles of their shoes covered with adhesive film. After use, the balance of physical characteristics of the film allows the user to remove the entire sole-shaped piece of adhered film from their shoes in a single pull, rather than having the adhered portion fragment upon being pulled.
A system, method and computer-readable media are disclosed which apply a customized sole-shaped pad to footwear, such as a shoe or sandal. Throughout this disclosure references to a shoe, sandal, or other footwear, are interchangeable. Various embodiments of the disclosure are described in detail below. While specific implementations are described, it should be understood that this is done for illustration purposes only. Other components and configurations may be used without parting from the spirit and scope of the disclosure. A brief introductory description of a basic general purpose system or computing device in
With reference to
The system bus 110 may be any of several types of bus structures including a memory bus or memory controller, a peripheral bus, and a local bus using any of a variety of bus architectures. A basic input/output (BIOS) stored in ROM 140 or the like, may provide the basic routine that helps to transfer information between elements within the computing device 100, such as during start-up. The computing device 100 further includes storage devices 160 such as a hard disk drive, a magnetic disk drive, an optical disk drive, tape drive or the like. The storage device 160 can include software modules 162, 164, 166 for controlling the processor 120. Other hardware or software modules are contemplated. The storage device 160 is connected to the system bus 110 by a drive interface. The drives and the associated computer-readable storage media provide nonvolatile storage of computer-readable instructions, data structures, program modules and other data for the computing device 100. In one aspect, a hardware module that performs a particular function includes the software component stored in a tangible computer-readable storage medium in connection with the necessary hardware components, such as the processor 120, bus 110, display 170, and so forth, to carry out the function. In another aspect, the system can use a processor and computer-readable storage medium to store instructions which, when executed by the processor, cause the processor to perform a method or other specific actions. The basic components and appropriate variations are contemplated depending on the type of device, such as whether the device 100 is a small, handheld computing device, a desktop computer, or a computer server.
Although the exemplary embodiment described herein employs the hard disk 160, other types of computer-readable media which can store data that are accessible by a computer, such as magnetic cassettes, flash memory cards, digital versatile disks, cartridges, random access memories (RAMs) 150, read only memory (ROM) 140, a cable or wireless signal containing a bit stream and the like, may also be used in the exemplary operating environment. Tangible computer-readable storage media expressly exclude media such as energy, carrier signals, electromagnetic waves, and signals per se.
To enable user interaction with the computing device 100, an input device 190 represents any number of input mechanisms, such as a microphone for speech, a touch-sensitive screen for gesture or graphical input, keyboard, mouse, motion input, speech and so forth. An output device 170 can also be one or more of a number of output mechanisms known to those of skill in the art. In some instances, multimodal systems enable a user to provide multiple types of input to communicate with the computing device 100. The communications interface 180 generally governs and manages the user input and system output. There is no restriction on operating on any particular hardware arrangement and therefore the basic features here may easily be substituted for improved hardware or firmware arrangements as they are developed.
For clarity of explanation, the illustrative system embodiment is presented as including individual functional blocks including functional blocks labeled as a “processor” or processor 120. The functions these blocks represent may be provided through the use of either shared or dedicated hardware, including, but not limited to, hardware capable of executing software and hardware, such as a processor 120, that is purpose-built to operate as an equivalent to software executing on a general purpose processor. For example the functions of one or more processors presented in
The logical operations of the various embodiments are implemented as: (1) a sequence of computer implemented steps, operations, or procedures running on a programmable circuit within a general use computer, (2) a sequence of computer implemented steps, operations, or procedures running on a specific-use programmable circuit; and/or (3) interconnected machine modules or program engines within the programmable circuits. The system 100 shown in
Having disclosed some components of a computing system, the disclosure now turns to
The pins 212 associated with the plate 208A extend through the plate 208A using aligned holes to the initial height 224A, and are capable of being compressed using springs, hydraulics, underlying resistance elements or other mechanisms. An example of the pins 212 and plate 208A mechanism is provided by Benson et al., U.S. Pat. No. 6,654,705, issued Nov. 25, 2003, which is hereby incorporated in its entirety. As described and illustrated by Benson et al., the pins can be used to define the perimeter of a user's foot, or shoe, by placing the user's shoe onto the plate/pins device. In addition to the perimeter of the shoe, the plate/pins combination disclosed by Benson et al. can also be used to measure the vertical contours of the sole itself.
Below the pins, the device 200 can have a layer of elastomeric material 214 which can cushion the pins 212. On either side of the plate 208, pistons 210, or mechanical elevators, help raise and lower the plate 208A before and after use. The pistons 210 can be hydraulic, mechanical (such as a screw mechanism), springs, or any acceptable raising and lowering mechanism, and can operate automatically or based on instructions from a processor or computing device 228. In circumstances where the person is not standing on the doormat 200, the pistons maintain the plate 208A at a specified height 224A, just below the adhesive film 202A. Operations of the device 200 can be initiated via processor 228, as described by the system 100 of
The processor 228, or a control system, can further control any additional hydraulics or tension systems located in the device 200. For example, if a known user approaches the device 200, the tension in the pins 214 can be adjusted based on the weight of the known user. Alternatively, the initial height or tension 224A of the plate 208A and/or pins 212 may be adjusted based on time of day, temperature, weather conditions, or frequency of device use. Any number of adjustments and control decisions can be determined by the processor 228 based on specific input or via a user interface, such as a graphical user interface, a keyboard, a keypad, a microphone, optical scanner, or other input means.
Prior to receiving a shoe 216, and in preparation for receiving contact with a shoe, in accordance with the principles disclosed herein, the device 200 will spool a portion of unused adhesive film 204 into a fixed position. To initiate spooling, users can provide specific input or the system can spool based on a number of factors. For example, after a person leaves the doormat, the system can immediately, or after a predetermined period of time (e.g., like 10 seconds), initiate spooling to position fresh unused adhesive film 204. However, having unused adhesive film in position for too long may result in dust, grass, or other debris being blown on or settling on the adhesive film 204 thus reducing its effectiveness. Thus, in one aspect, the system will, via motion detection, sound detection or any other known mechanism, detect when a person is approaching the doormat and then spool the adhesive film 204. Where specific input is used, the specific input can include input provided by motion detection of a user, a voice command, a radio frequency identification, or input provided by a user manually pressing a button indicating that the user is in position to use the device 200. The spooling can be triggered by a location based service in which the system received a communication that a particular user's smartphone is approaching the doormat. Thus, existing location-based technology can result in an identification of a person in general or a particular person and the doormat can be adjusted and configured to improve the application of the adhesive to that person's shoes.
Alternatively, spooling can occur in the absence of any specific input, or after a time period of receiving no input. In certain embodiments, the user stepping onto the device 200 can compress a spring or other mechanism which, when the user steps off of the device 200 and releases the tension of the spring, spools the adhesive film. Upon spooling the adhesive film 202A into the fixed position, the device 200 is prepared to allow a user to step onto the adhesive film 202A with both feet.
Portion (B) represents when a user has stepped onto the device 200, placing their foot, having a shoe 216 thereon, onto the adhesive film 202A. When the user steps onto the device 200, placing the shoe into a shoe receiving area, multiple components of the device 200 can interact simultaneously or in direct succession. For example, upon receiving the shoe 216, the adhesive film 221 immediately below the sole of the shoe 216 adheres to the sole. The plate 208B beneath the user's shoe 216 lowers from the original height 224A to height 224B, resulting in a height differential 224C. The pins 220 directly beneath the sole of the shoe 216 are compressed to height 224B, and any elastomeric material 218 beneath the sole of the shoe 216 may be similarly compressed. The compression can occur based on the weight of the user and/or shoe, or based on instructions from the computer processor 228.
While the pins 220 directly below the sole of the shoe 216 compress to height 224B upon receiving the shoe, the remaining pins 222 pass through the lowered plate 208B, remaining at the original film height 224A. The remainder pins 222 hold the remainder portion of the adhesive film 202B (i.e., the film not immediate below the sole of the shoe) at the original film height 224A. The resulting height difference 224C between the portion of the film attached to the sole 221 and the remainder portion 202B of the film results in a tearing, or shearing, of the remainder portion 202B in a pattern matching the sole of the shoe 216. This tearing, or shearing, can be due to the vertical adhesive force of the adhesive film attached to the shoe 221 exceeding the lateral adhesive force of the adhesive film 202B not attached to the shoe. Micro-perforations throughout the adhesive film 202 can aid the tearing/shearing action.
After the adhesion of the film to the shoe, the user steps off the doormat 200. At this point the soles of the user's shoes have adhesive film 221 attached. When the user has stepped onto the doormat 200 with both feet, the remaining adhesive film 202B has two large holes corresponding to the portions attached to the user's shoes. The device 200 can then spool the used adhesive film 202B into a waste bin 206. The removal of the used adhesive film 202B can occur immediately, or can occur upon receiving additional input indicating a user is preparing to use the device 200.
In practice, occasions may dictate that a user could place one shoe at a time into the device 200, or could place both shoes in the device simultaneously. Should the user place only a single shoe in the device 200, the device can detect, by means of sensors associated with the plate 208, the mechanical elevators, the pins 212, or the elastomeric material 214, that one side of the device 200 has not yet been used. The device 200 can determine, based on the sensor feedback, that only one side of the adhesive film has perforations. When such a determination is made, the control system can instruct the spooling mechanism to only distribute a portion a portion of the normal distribution size of adhesive film 202A. For example, if a normal distribution of adhesive film has a width of 20″ for both feet, upon detecting use of only a single foot the device 200 can distribute adhesive film having a width of 10″. This prevents an unused portion of the adhesive film 202A from being wasted by erroneously directing the adhesive film 202A to waste collection 206.
When a user places a shoe 314 or shoes into the device 300, the adhesive material 302 between the shoe 314 and the stationary plate 328 is adhered to the shoe. Additionally, the elevator 306 is raised from an original height 324A to a raised height 324B by the pistons 308, a difference of 324C. In raising the elevator 306, the elastomeric material 322 and the pins 316 on the elevator 306 are also raised. This results in compression of pins 316 directly beneath the sole 314 of the shoe and/or compression of the elastomeric material 322. Pins on the elevator 306, but not directly beneath the sole 314 of the shoe (i.e., the remainder pins 318) are not compressed between the elevator 306 and the shoe 314. Instead, the remainder pins 318 are raised up with the raising of the elevator 306, and extend through the stationary plate 328. The remainder pins 318 lift the portion of the adhesive film 320B not directly beneath the shoe 314.
Because of the difference in height between the adhered portion 320A and the remainder portion 320B, the adhesive film 302 tears or shears in a shape corresponding to the shape of the shoe's sole. As the user removes the shoes from the device 300, the shoes have the adhered portion 320A attached to the soles. The remainder portion 320B has two holes in the adhesive film 302 where the portions corresponding to the adhered portions 320A were once located. The remainder 320B is later discarded and/or collected. The device 300 then instructions the pistons 308 to return the elevator 306 to the original height. In addition, the compressed pins 316 can return to an uncompressed state. In alternative embodiments, the device 300 can contain multiple elevators, rather than two as illustrated. In yet other embodiments, the device 300 can contain a single elevator for both the left and right feet, rather than separate elevators as illustrated.
The elevators 306 are illustrated as a raising or lowering the entirety of the pins 316 simultaneously. In other variations of the elevators 306, a roller elevator or mechanism can be used to push/compress the pins upward as the roller passes beneath the user's feet. A roller (or rolling) elevator is not illustrated in
The system 200 then applies the adhesive film to the sole of the shoe, by cutting a sole-shaped portion of the adhesive film via a sole-shaped demarcation and shearing. The sole-shaped demarcation and shearing is achieved using a height differentiation (404) associated with pins. For example, the weight of the user can result in a lowering of the adhesive film portion directly beneath the sole of the shoe from an original height 224A to a lower height 224B, while the remainder portion remains at the original height 224A. The resulting difference in height 224C results in a shearing of the adhesive film in a shape corresponding to the shape of the sole.
The lowering of the adhesive film can be assisted by lowering of a plate and associated pins, which extend through the plate and can be compressed from the original height to the lower height. The pins directly beneath the sole of the shoe will be compressed to the lower height 224B, while those pins which are not directly beneath the sole of the shoe will extend through the lowered plate to remain at the original height 224A. The pins which remain at the original height can retain a remainder portion of the adhesive film, resulting in shearing of the adhesive film.
Alternatively, the height differentiation can be accomplished by raising the pins which are not directly beneath the sole of the shoe to a second height and keeping the pins directly beneath the shoe at the original height.
The micro-perforations, or other structure that enables a balance of shearing/tearing forces as described herein, can be uniform or non-uniform throughout the adhesive film. For example, the micro-perforations might be patterned in every increasing sole shapes, starting with micro-perforations in the shape of a small sole and increasing, over multiple iterations, to micro-perforations in the shape of a large sole. As another example, the micro-perforations may be evenly distributed in a uniform pattern throughout the adhesive film, and not in any particular shape. In yet another example, the micro-perforations can be randomly distributed throughout the adhesive film, not following any ordered scheme. In any distribution of the micro-perforations, the distribution of micro-perforations can have minimum threshold distances between the micro-perforations, where the minimum threshold distance between micro-perforations is calculated to allow for tearing or shearing of the adhesive film at a given height differential, or when a given amount of tension is achieved within the adhesive film.
In configurations with or without micro-perforations, the adhesive film can have a balance of physical characteristics where the force required to vertically shear the film is greater than the force to perform lateral tearing. The user, after adhering the film to the sole of the shoes, can walk away with the soles of their shoes covered with adhesive film, thereby preventing tracking of dirt into the house or office. When the user wants to remove the adhesive film from the soles of the shoes, the balance of physical characteristics of the film allows the user to remove the entire sole-shaped piece of adhered film from their shoes in a single pull, rather than having the adhered portion fragment when pulled.
Upon receiving a signal or indication that the user is in position from the sensor 602, the device 600 moves, via spooling or other distribution methods, adhesive film 604 from a storage area 606 over a predetermined usage area. The device 600 identifies that the adhesive film 604 is moved into a correct position using positional markers 608. The adhesive film 604 illustrated has two sections 612 having micro-perforations as well as drawings indicating approximate places for shoe placement. When the adhesive film is positioned correctly, the sections 612 will correspond to plates and pins illustrated in
Certain embodiments can have speakers 610 which output speech and instructions to the user. For example, the device 600, upon recognizing a specific RFID, and while spooling new unused adhesive film into position, can output speech such as, “Welcome back Dr. Smith. Please step forward.” If being used at home, the device 600 could state, “Welcome to the Smith home. Please step onto the platform.” In addition, the device 600 can be equipped with access to the Internet or other resources which identify reasons for why the device 600 might be needed in any particular instance. For example, the device 600 may determine that it is raining, and state when the motion sensor is triggered, “Due to the rain, please use the provided adhesive shoe protection.” As another example, the device 600 may be aware that spills have been detected in a supermarket, and subsequently may produce speech stating, “For your safety, please use the provided adhesive traction for your shoes.”
Embodiments having more than two layers are also considered. For example, an embodiment could have five or six layers within the adhesive film. In addition, these layers may have elements which extend through every layer. For example, in an adhesive film which is also meant to provide ESD (electrostatic discharge) protection, a grounding element can extend from the lowest layer up to the portion which adheres to the shoe, completing the ESD circuit.
In yet other embodiments, the adhesive film can have multiple layers where the top layer, when cut by pins, adheres to the shoe. The bottom layer of the adhesive film remains uncut as a single continuous piece, rather than having a hole corresponding to the removed adhesive portion. As a non-limiting example this is similar to a sticker having a backing. In this case, the “sticker” would be adhesive to the sole of a shoe, leaving a continuous bottom layer of film (i.e., the backing) while the top adhesive layer of film has portions corresponding to the adhered-portions (i.e., the blank area where the sticker used to be located). The continuous bottom layer can have an elastic quality, allowing it to deform/stretch when the height differential exits without tearing. In such an example, the top layer would tear, while the bottom layer stretches and remains continuous. This can be advantageous in collecting the used portions of the adhesive film, as a continuous unused portion is easier to collect than portions having holes. For example, rolling a continuous layer of film can be easier than rolling a layer of film having holes
The first, adhesive, layer can be proximal to the sole of the shoe, while the second, traction, layer is respectfully distal to the sole. In addition, the adhesive film can be organized into a roll, or alternatively, can be a rolling material. In various configurations, the first layer or the second layer may be exclusively micro-perforated, while the other layer is not micro-perforated. In other embodiments, the two layers can have mismatched patterns of micro-perforations, such that the micro-perforations of the adhesive layer do not align with the micro-perforations of the traction layer.
The adhesion process occurs by application of force between the sole of the shoe and the adhesive film. In certain instances, the force is from the weight of the shoe pressing down upon the adhesive film, whereas in other instances the force is from pins beneath the sole pressing upward toward the sole. This second example can, for example, occur when a plate lifts pins upward and only some of the pins are directly beneath the sole, resulting in remainder pins not pressing into the sole but instead lifting the remainder of the adhesive film to a height higher than the original height.
The device 1102 as illustrated has cartridge receiving areas 1109 on both the left and right of the device 1102, as well as a shoe receiving area 1116 including material elevators, pins, and plates with holes corresponding to the pins. Within the left and right cartridge receiving areas 1109 are slots 1104, 1106 for holding pieces the square housing containers 1110 of the cartridge 1108 in place when the cartridge 1108 is inserted into the device 1102. These slots 1104, 1106, also have pins or shafts 1103, 1105 corresponding to the cartridge rolls 1112. the shafts 1103 can control the unrolling of the unused adhesive film from the first roll 1112 in the cartridge 1108, and/or can similarly control the rolling of the used adhesive film on the second roll 1112 in the cartridge 1108.
The user, when placing a cartridge 1108 into the device 1102, can line up the left and right portions of the cartridge 1108 with the corresponding cartridge receiving areas 1109 of the device 1102. As the user places the cartridge 1108 into the device 1102, the device can lock the cartridge into place using the pins 1103, 1105 and/or other locking mechanisms. The adhesive film 1114 between the right and left portions of the cartridge 1108 slides over the shoe receiving area 1116. As the device 1102 is used, the unused adhesive film is spooled from a first roller 1112 to the shoe receiving area 1116, users adhere the film to their footwear, and then the used adhesive film is collected on the second roller 1112. Later, when the user needs to replace the cartridge (i.e., the cartridge is empty, or the viability of the adhesive film has expired), the user removes the cartridge 1108 from the device 1102.
