[0030] The present disclosure describes various embodiments related to a grating fastener system, assembly, and associated methods for reduced risk of injury while performing work in an industrial site, such as lock-out tag-out system for grating work. Gratings, such as grating panels, are utilized in multiple industrial sites. For example, offshore platforms use gratings as flooring for weight reduction purposes and chemical plants use gratings for tall structures to view workers from below, among other reasons. These gratings may be subjected to corrosive environments necessitating repairs or replacements of the grates. Conventionally, grating repairs or replacements are performed by use of safety tape, such as caution tape, about a perimeter to alert others of the potential opening in the flooring. Furthermore, the grating repairs or replacements may be performed with surrounding operating equipment. These problematic environments for performing grating work may increase the risk of injury of personnel leading to increased operational costs and a reduced personnel moral. Implementation of proper training, tools, and techniques to perform grating work has not achieved a suitable reduction of risk for injury to personnel. As such, the present disclosure significantly reduces the risk of injury for grating work performed in an industrial site by implementing a lock-out tag-out technique for obtaining a bit that drives a keyed fastener grating assembly.

[0031] The description may use the phrases “in certain embodiments,” “in various embodiments,” “in an embodiment,” “in one embodiment, or “in example,” which may each refer to one or more of the same or different embodiment. Furthermore, the terms “comprising,” “including,” “having,” and the like, as used with respect to embodiments of the present disclosure,are synonymous. The term “plurality” as used herein refers to two or more items or components. The terms “about” or “approximately” are defined as being close to as understood by one of ordinary skill in the art. In one non-limiting example, these terms are defined to be within 10%, preferably within 5%, more preferably within 1%, and most preferably within 0.5%.

[0032] The terms “removing,” “removed,” “reducing,” “reduced,” or any variation thereof, when used in the claims and / or the specification includes any measurable decrease of one or more components in a mixture to achieve a desired result. The use of the words “a” or “an” when used in conjunction with any of the terms “comprising,” “including,” “containing,” or “having,” in the claims or the specification may mean “one,” but it is also consistent with the meaning of “one or more,” “at least one,” and “one or more than one.” The terms “wt. %”, “vol. %”, or “mol. %” refers to a weight, volume, or molar percentage of a component, respectively, based on the total weight, the total volume of material, or total moles, which includes the component. In a nonlimiting example, 10 grams of a component in 100 grams of the material is 10 wt. % of the component. Furthermore, dimensional data presented within the disclosure include a + / - 5%. In a non-limiting example, a 10 inch data point has + / - 5% margin therefore, the data point range is defined as about 9.50 inch to about 10.50 inch.

[0033] For purposes of understanding, the lock-out tag-out operations disclosed below adopt the definition of the lock-out tag-out from Occupational Safety and Health Administration’s “OSHA” website. The definition is provided as “LOTO or lockout / tagout is a safety procedure used to ensure that dangerous equipment is safely shut off and cannot be restarted until maintenance or repair work is completed. This includes anything from shutting down electrical circuits and valves to neutralizing extreme temperatures and securing moving parts. LOTO protects workers against sudden equipment or machinery startups that could harm or kill them if not properly controlled.” “Lockout and tagout differ in the type of devices they use, though they work in tandem. While the tagout device alerts workers that the equipment should not be operated, the lockout device physically prevents workers from running the equipment. In essence, a tagout device is the first line of defense against harmful equipment usage, while a lockout device is the second.” “To lock out equipment is to secure it with a lock that prohibits energy release.” “Doing so allows for trained workers to use equipment when it is safe to do so. During servicing and maintenance activities, locking out is used to prevent the unexpected activation or energizing of machinery and equipment.” “Tagout refers to warning tags that advise against turning on a switch or otherwisepowering equipment. To tag out a piece of equipment is to attach a visible tag to a switch to warn people not to turn it on. Unless locking out the equipment is impractical, tagout should only be used in conjunction with lockout.”

[0034] FIGS. 1A-1F are environmental views of an embodiment of a grating fastener system using lock-out tag-out operations for grating work in an industrial site, according to an embodiment of the present disclosure. FIG. 1A illustrates an offshore platform 100 having a topsides 102 and a hull 104 positioned over a body of water 106. The topsides 102 may include various operational equipment such as, for example, an oil derrick 108, a pump 110 and associated pump motor 120, and the like, as will be understood by those skilled in the art. The topsides 102 may further include operational buildings such as a control room 112, living quarters (not shown), or the like, as will be understood by those skilled in the art. FIG. 1A shows the oil derrick 108, the pump 110 and associated pump motor 120 in the operational “on” position, and the control room 112 positioned in four sections of the topsides 102, labeled as “zone” and followed by a numerical identifier. In one embodiment, the topsides 102 has four sections, zone 1-4, however, an industrial site may have a varied number of zones. Each of the zones 1-4 have gratings 116 attached to the topsides 102 via grating fasteners 114. Each of the grating fasteners 114, discussed in greater detail below, have a keyed recess to receive a keyed extension of a bit to drive the grating fastener 114. In one embodiment of the present disclosure, the keyed extension of the bit, used to drive the grating fasteners 114 of each zone 1-4, are not compatible to drive the keyed fasteners of another zone. Stated differently, each of the zones 1-4 will have a unique keyed grating fastener 114 such that, for example, a keyed extension of a bit that drives a keyed grating fastener 114 of zone 1, will not be able to drive the keyed grating fastener 114 of zone 2, zone 3, or zone 4, and vice versa. Moreover, the bit, as discussed above and in greater detail below, may be available for use on a tool by a lock-out tag-out procedure. While FIG. 1A illustrates an offshore platform 100, it is to be understood an industrial site may include various locations on land, boat, or on bodies of water.

[0035] In one embodiment as shown in FIG 1A, for example, the grating fastener system using a lock-out tag-out procedure may begin with a worker 118 tasked with repairing a grating positioned within zone 1. The worker 118 enters the control room 112 and may be instructed by the head operator (not shown) of the location of the zone 1 bit for the grating work. Once the worker 118 is instructed of the location of the bit within the control room 112, the worker 118 may be assigned a key 122 to gain access to a lock-out station 128 positioned within cabinet 124 thathouses the unique bits. In one embodiment, the key 122 may unlock one of a plurality of locking mechanisms, including lock-out tag-out cabinets, security measures, safety charting panels, or the like, as would be understood by those skilled in the art. In one embodiment, for example, the lockout station 128 may be connected to a controller 126 operable to record information, such as, for example, which bit is removed from the lock-out station 128. In one embodiment, the controller 126 is connected to a ledger (such as shown in FIG. 11) to maintain records of information related to activity within the cabinet, such as removal or the return of a bit designated to a particular zone. In yet another embodiment, the controller 126 sends alerts, or alarms, to inform other personnel on the offshore platform 100 that an activity will commence, or conclude, using a component, such as a bit, positioned within the cabinet 124. The controller 126 may have a variety of functions, as discussed above, to provide information of any lock-out station 128 activity and to generally generate a group of patterns custom to a site, or portions of a site, and periodically change those as may be requested by a customer with relative ease to enhance security if desired.

[0036] Turning to FIG. 11, FIG. 11 is a simplified diagram illustrating a control system 1100 for managing the data collected from the lock-out tag-out procedure using, for example, the lock-out station 128, according to one embodiment of the disclosure. In some examples, the control system 1100 includes the controller 126 or one or more controllers. Certain examples include the controller 126 being in signal communication with various other controllers throughout or external to an industrial site, such as the offshore platform 100, discussed above. Additionally, the controller 126 may be considered a supervisory controller or other suitable control component for managing the lock-out tag-out procedure, as discussed herein. The controller 126 of various examples disclosed herein include one or more processors, such as processor 1104, in communication with a memory or machine-readable storage medium, such as memory 1106. As used herein, a “machine-readable storage medium” may be any electronic, magnetic, optical, or other physical storage apparatus to contain or store information such as executable instructions, data, and the like. For example, any machine-readable storage medium described herein may be any of random access memory (RAM), volatile memory, non-volatile memory, flash memory, a storage drive, a hard drive, a solid state drive, any type of storage disc, and the like, or a combination thereof. The memory 1106 stores or includes instructions, such as one or more software programs, executable by the one or more processors, such as processor 1104. As used herein, a “processor” includes, for example, one processor or multiple processors included in asingle device or distributed across multiple computing devices. The processor 1 104 may be at least one of a central processing unit (CPU), a semiconductor-based microprocessor, a graphics processing unit (GPU), a field-programmable gate array (FPGA) to retrieve and execute instructions, a real time processor (RTP), other electronic circuitry suitable for the retrieval and execution instructions stored on a machine-readable storage medium, or a combination thereof. Also, as used herein, “signal communication” refers to electric communication such as hard wiring two components together or wireless communication, as understood by those skilled in the art. For example, hard wiring two components may be by modbus, profibus, industrial ethemet, foundation fieldbus, or the like, while wireless communication may be Wi-Fi®, Bluetooth®, ZigBee, or forms of near field communications. In addition, signal communication may include one or more intermediate controllers or relays positioned between elements that are in signal communication with one another. Therefore, the controller 126 includes instructions to commence or conclude the lock-out tag-out procedure 1108 according to the examples disclosed herein.

[0037] Referring back to FIG. IB, as shown, the cabinet 124 contains the lock-out station 128. The lock-out station 128 has several casing structures 132, each assigned to a varied zone. The casing structures 132, as discussed in greater detail below, house the unique bits. The worker 118 may gain access to the cabinet 124 and use the key 122 to open a lock 130 that secures the casing structure 132 locked closed. In one embodiment, the lock 130 may be a digital combination lock with a key override, a digital encryption lock, or the like, as will be understood by those skilled in the art. As illustrated in FIG. 1C, the worker 118 may gain access to the bit 134 designated for zone 1, as shown in FIG. IB. In one embodiment, the worker 118 takes possession of the lock 130 and the bit 134 designated for zone 1. As discussed above, the controller 126 may record information related to the worker 118 taking the bit 134 and the lock 130 in possession and provide that information to the ledger (such as shown in FIG. 11) for historical records. In one embodiment, the controller 126 may contain information about the worker 118 and frequency of lock-out tag-out procedures, as discussed in FIGS. 1A-F.

[0038] FIG. ID shows the worker 118 with possession of the bit 134 and the lock 130. The worker 118 may also possess warning tags (as shown in FIG IE) and any necessary tools (as shown in FIG. IF) to perform work on the grating 116. FIG. ID further shows the worker 118 approaching zone 1, the location of the grating 116 in need of repair and the location of operational equipment, such as pump 110 and associated pump motor 120. FIG. IE illustrates the worker 118positioning the lever 136 from the “on” position to the “off’ position, thereby to shut down the operation of the pump 110. Furthermore, the worker 118 may use the lock 130 to secure, and lock, the lever 136 in the “off’ position, thereby to ensure the lever remains in the “off’ position. In one embodiment, the worker 118 may also tag the pump motor 120 in the “off’ position with a tag 138 to caution others that the pump motor 120 must remain in the “off’ position. In one embodiment, for example, the tag 138 may be a sign that states a date, time, “Caution”, “Danger”, “Warning”, “Do not operate”, “Do not cut”, “Must be removed by: [worker signature, or name]”, “Intentionally out of service”, or the like, as will be understood by those skilled in the art that such equipment should not be energized, or activated, without authoritative override of clearance to operate. In some embodiments, the worker may also provide information on the tag 138 of their location of grating work to provide the reader, or other personnel, a location to seek the worker 118.

[0039] FIG. IF illustrates the lever 136 of the pump motor 120 in the “off’ position with the lock 130 and the tag 138 positioned thereon. As shown, the worker 118 is using a handheld tool, such as a drill 140, to fasten or unfasten the grating fastener 114 in zone 1 to perform the necessary grating repair, or installation, of gratings 116 with a significantly reduced risk of injury as nearby operating equipment is not energized, and thus, not operating. As previously discussed, the grating fastener 114 in zone 1 is not operable to interface with the bit 134 with a grating fastener of zone “n” (wherein “n” is a number different than “1”), for example.

[0040] The worker 118 may reverse the disclosed lock-out tag-out procedure discussed above to return the bit to the casing structure 132 positioned in the lock-out station 128 within control room 112 when the grating work is completed, or otherwise stopped.

[0041] While the above disclosure illustrates an exemplary grating fastener system using a lockout tag-out procedure, it is to be understood that varied lock-out tag-out processes may exist and be in implementation in industrial sites. Furthermore, the grating fastener system, as described, may be incorporated into existing and operational lock-out tag-out processes. The grating fastener system also includes the individual components of the grating fastener 114, discussed below.

[0042] FIG. 2A is a sectional representation of an embodiment of a bit 200, according to an embodiment of the present disclosure. FIG. 2A shows the bit 200 that may be defined, for example, by a body 202 having an underside surface 206, an upper-side surface 208, an upper portion 210, a lower portion 212, and a recess 204 within the body 202. In one embodiment, the upper portion 210 has a length 214 greater than a length 216 of the lower portion 212. In anotherembodiment, for example, the bit 200 may have a height of about 1 inch to about 1 .25 inch, such as about 1.07 inch to about 1.19, such as about 1.12 inches. The lower portion 212 may have a keyed extension 218 extending in a direction away from the upper-side surface 208. In one embodiment, the underside surface 206 is positioned at an end 220 of the keyed extension 218. In another embodiment, for example, the keyed extension 218 may have a length of about 0.10 inch to about 0.35 inch, such as about 0.19 inch to about 0.29 inch, such as about 0.24 inches. In yet another embodiment, the upper-side surface 208 may have the recess 204 further including a first recess portion 222 and a second recess portion 224. In one embodiment, for example, the first recess portion 222 may have a depth of about 0.30 inch to about 0.60 inch, such as about 0.44 inch to about 0.54 inch, such as about 0.49 inches. In another embodiment, for example, the second recess portion 224 may have a depth beyond the depth of the first recess portion 222 of about 0.06 inch to about 0.26 inch, such as about 0.11 inch to about 0.21 inch, such as about 0.16 inches. In still another embodiment, for example, the second recess portion 224 may have a depth referenced from the upper-side surface 208 of about 0.50 inch to about 0.80 inch, such as about 0.60 inch to about 0.70 inch, such as about 0.65 inches. The second recess portion 224 may positioned a depth greater than the first recess portion 222. In one embodiment, the second recess portion 224 is positioned at a depth substantially near or within the lower portion 212 of the bit 200. In one embodiment, for example, the transition between the first recess portion 222 and the second recess portion 224 includes a lip 226 that faces inward towards a Center Line (“C / L”) of the bit 200. In one embodiment, the recess 204 is configured to receive one or more handheld tools for moving the bit 200, such as, for example, a rachet, drilling tool, an adaptor, or the like, as understood by those skilled in the art. In another embodiment, the first recess portion 222 and the second recess portion 224 are configured to receive a different tool to drive the bit 200. Stated differently, the first recess portion 222 is configured to receive a tool to drive the bit 200 that is different and not compatible with the second recess portion 224. For example, in one embodiment, the first recess portion 222 is configured to receive a 3 / 8-inch square drive and the second recess portion 224 is configured to receive a 3 / 16-inch hex drive. Therefore, the bit 200 is advantageously compatible with a large number of tools to drive the bit 200, thereby to allow a user flexibility in the tools available to drive the bit 200.

[0043] FIG. 2B is a top view representation of an embodiment of a bit, according to an embodiment of the present disclosure.

Stated differently, the user may tag the locked and shut down equipment with a sign to inform others that work is being performed locally and that the equipment should not be initiated, or otherwise energized.

[0065] At block 912, the user may use the assigned bit to perform any repair work on the plurality of gratings within the first zone. Further, each of the plurality of gratings may be secured to the support surface by the first plurality of fasteners. As discussed above, each of the fasteners has a keyed recess operable to receive and to matingly interface with the keyed extension from the assigned bit when positioned therein and further has an inner recess extending into the fastener from a bottom surface. In one embodiment, the inner recess is operable to receive a fastening device 606 secured to a support surface such as, for example, a threaded stud secured to a support surface 604, as shown in FIG. 6.

[0066] At block 914, the user may remove the sign, such as tag 138, on the locked operational equipment. The action of removing the tag 138 informs other users, or workers, that the first zone is cleared for activity as work may no longer be in progress, or otherwise being performed.

[0067] At block 916, the user may switch the operational equipment positioned within the first zone to a “ready” mode (not shown in FIGS 1A-1F). As would be understood by those skilled in the art, some operational equipment has various modes, such as “on”, or “running”, “off’, and “ready, or “stand-by” modes. Each operational equipment having a mode setting, may send signals, or status indication, to the controller 126, as illustrated in FIG. 11. In particular, the “ready”, or “stand-by” modes may be used in safe charts for start-up procedures of variousequipment signaling the equipment is, for example, primed, or the like, as would be understood by those skilled in the art.

[0068] At block 918, the user may return the assigned bit to the corresponding casing structure after work has been performed. As shown in block 920, the controller 126 may log data corresponding the return of the assigned bit to record information, such as duration, workers involved, or the like, and to inform other users, such as the head operator, that the first zone is cleared for activity. At block 922, the user may secure the locking device, such as lock 130, to the casing structure 132 with the assigned bit positioned therein. The method 900 may conclude with the starting the operational equipment positioned within the first zone as work has been completed on the gratings, thereby substantially reducing risk of injury from performing grating repair, or installation, work in an industrial site by implementing the exemplary method 900 associated to the grating fastener system and assembly.

[0069] Furthermore, while not illustrated in FIG. 9, the method 900 may be repeated for grating work required in a different zone, such as zone 2, zone 3, or zone 4, as shown in FIG. 1A & ID. In those embodiments, the users may be assigned a second bit having a keyed extension inoperable to matingly interface with the keyed recess of the fasteners within zone 1, as discussed above. Therefore, as discussed above, the keyed extensions of the bits are only operable to fasten the fasteners having a corresponding keyed recess assigned to a designated zone of gratings.

[0070] FIG. 10 is a perspective view of a grating fastener system kit, according to one embodiment of the disclosure. In all embodiments, the grating fastener system kit 1000 includes a container 1002. The container 1002 may be a wrapper, a wooden or plastic box, a crate, or a pallet, wherein the container 1002 is configured to house or keep the components within the grating fastener system kit 1000 together or in a specific position. In one embodiment, the container 1002 has a locking feature or a tamper-resistant feature to reduce unauthorized or inadvertent opening of the container 1002.

[0071] FIG. 10 illustrates an embodiment of a grating fastener system kit 1000 for a grating fastener system and includes a first bit 200, a first casing structure 132 with the first bit identifying mark 818 and the second bit identifying mark 828 corresponding to the first bit 200 of the grating fastener system kit 1000, a plurality of first fasteners 300 keyed to receive the first bit 200 within the kit, a plurality of plates 460, and a plurality of bushings 420. In another embodiment, while not illustrated, the grating fastener system kit 1000 further includes a second bit, a second casingstructure identifying the second bit, a plurality of second fasteners keyed to receive the second bit within the kit, a second plurality of plates 460, and a second plurality of bushings 420. In yet another embodiment, the grating fastener system kit 1000 may further include a third bit and associated parts related to the third bit as described for the first bit 200 and the second bit within the kit.

[0072] In one embodiment, the grating fastener system kit 1000 includes more components as illustrated in FIG. 10 such as, for example, the plurality of bushing 420. In another embodiment, the grating fastener system kit 1000 includes fewer components as illustrated in FIG. 10. Further, it is to be understood by those skilled in the art that the grating fastener system kit 1000 also may include instructional manuals, video tutorials, degreaser packages, grease, cleaning wipes or cloth, adaptors, and / or the like, configured to fit the bit 200, positioned with the container 1002 such as for use during or instructions for grating panel repair or installation, as will be understood by those skilled in the art. The components as illustrated within the grating fastener system kit 1000 of FIG. 10 are not representative of the actual size, or quantity, but rather are enlarged to view component details and numerals.

[0073] As discussed above, FIG. 11 is a simplified diagram illustrating a control system 1100 for managing the data collected from the lock-out tag-out procedure using, for example, the lockout station 128, according to one embodiment of the disclosure. In one embodiment, a user interface 1110 may be positioned in the control room 112 as, for example, a computer screen, a handheld device, or the like, as would be understood by those skilled in the art. The user interface 1110 may communicate with the controller 126 that governs the lock-out tag-out procedure sequence 1108. It is to be understood the lock-out tag-out procedure sequence 1108 may be a sequence determined by end users, such as the industrial site, or the safety policy directed by the governing company of the industrial site. In one embodiment, a safety system 1150 may be communicating with the controller 126 to provide periodic, or real-time, updates on desired status of the offshore platform 100. Similarly, sensors on the operating equipment 1160 may provide status indication so as to provide the lock-out tag-out procedure sequence 1108 Boolean logic information to satisfy, for example, safe charts (not shown), as would be understood by those skilled in the art. Furthermore, as discussed above, the lock-out station 128 may record information directly to the ledger module 1131 to provide information of lock-out station activity 1130. In one embodiment, the ledger module 1131 is operable to record, for example, informationassociated with an assignment of a bit and the location where an assigned bit will be used, thereby to inform personnel of a location of work being performed when the assigned bit is in use, as discussed above. In one embodiment, as discussed above, the lock-out tag-out procedure sequence 1108 may have an override module 1141 that may energize operational equipment, such as pump 110, upon receiving an authoritative override 1140 from, for example, the head operator.

[0074] The controller 126 may further utilize instructions received by the user interface 1110 to, for example, order additional components of the fastener system, such as the bit, fastener, bushing, or plates to repair, or replace, installed components. Thus, the controller 126 may be in further signal communication, via signal communication 1170, with other controllers, such as controller 1302 from FIG. 13, via signal communication 1326, to request replacement unique components, or request additional components as those utilized by the end user. In some embodiments, the controller 126 is positioned at the industrial site while the controller 1302 is positioned at a location remote to the industrial site, such as a manufacturing facility for components of the fastener system. Additionally, the controller 126 and the controller 1302 may communicate information between each other, such as information on additional component orders, status of order fulfdlment, or the like information.

[0075] FIG. 12 is a flow chart of a method 1200 for generation of unique shapes applicable to a grating fastener system, according to an embodiment of the present disclosure. The method 1200 will be discussed using system reference numerals of FIG. 13. The method 1200 details exemplary controller 1300 operations for generating a plurality of unique shapes applicable to, for example, a bit 200 and a fastener 300 interface, as discussed above. It is to be understood that various commercial unique shape generator programs may be available. Furthermore, the aforementioned blocks of method 1200 do not need to be performed in sequence but rather may be performed as optional block operations or nonsequential block operations. In some examples, some of the blocks of method 1200 are bypassed, or skipped, as the block operation is unavailable.

[0076] The method 1200 may begin at block 1202 where a user may input, via a user interface 1314, a base shape into a controller 1302 configured to generate unique shapes from that base shape. The controller 1302 may be programmed to count shape components, such as sides, planes, joints, or both, and the like, as data points. For example, a user may input a base shape as a two dimensional triangle into the controller 1302. The controller 1302 may process the exemplary twodimensional triangle to contain three sides, zero planes, and three joints. The controller 1302 may utilize these data points as desired parameters to generated unique shapes thereafter.

[0077] The method 1200 may also begin at block 1204 where a user may input, via a user interface 1314, a guideline into the controller 1302 configured to generate unique shapes that adhere to, or not deviated from, the input guideline(s). For example, a user may input a guideline to generate, or not to generate, shapes with, for example, greater than four sides, more than four contact sites (between a bit 200 and a fastener 300 when used), desired insertion depth, desired printer cut depth, or the like parameters, as would be understood by one skilled in the art. The controller 1302 may utilize these input guidelines as restriction parameters to remove, or prevent, generation of shapes extending beyond the boundaries of the guidelines.

[0078] The operations of blocks 1202 and 1204 may be optional inputs into the controller 1302. In some examples the user may desire to generate shapes absent limitations, such as an input base shape or input guidelines.

[0079] At block 1206, the method 1200 may generate one or more unique shapes. For example, the unique shape generator sequence module 1308 may generate 10 or more, 50 or more, or 100 or more unique shapes at a time. To facilitate understanding, unique shapes are shapes that differ from each other and not repeated, thus every shape generated is distinct from the other shapes generated.

[0080] The generated unique shapes of diamond 1208 may be evaluated within the controller 1302 to verify each of the generated unique shapes adhere to the inputs, such as from blocks 1202 and 1204, or not repeated. If the generated unique shapes do not meet requirements, that generated shape may be recycled to block 1206 for regeneration, thus providing a new unique shape for evaluation of meeting requirements of the inputs. If the generated unique shapes meet requirements, those generated unique shapes are provided to the user in a database for selection.

[0081] At block 1210, the user may evaluate the generated unique shapes to select any desired shapes for extraction at block 1212. In some examples, the selection of the desired shapes may be automated via a ranking of parameters satisfied, per the input(s) requirement(s). The selected shapes are extracted at block 1214 and then logged with unique serial numerals at block 1214. The operation of logging the extracted unique shape files with unique serial numerals may be categorized in a database, such as a ledger module 1310, for example, to differentiate between end users. One such example of a ledger module 1310 may be Excel®, or the like databases for storageof unique serial numerals to associated unique shape files. For example, selected shapes for one end user, such as a client using the bit 200 and a fastener 300 system from above, may be logged with distinct serial numerals, different than those shapes generated, selected, extracted, and logged, for a different end user, thereby to reduce, substantially eliminate, or prevent, a risk of providing two end users with the same shape for used on their bit 200 and a fastener 300 system.

[0082] The method 1200 may continue from block 1214 by prompting the user to create additional unique shapes for an end user at diamond 1216, or to print one or more shapes of the unique shape generated, selected, extracted, and logged at diamond 1218. At diamond 1216, if the user selects to create additional shapes for a particular end user, the operation sequence recycles to block 1206. If the user selects to not create additional shapes, the method may conclude at end block 1220. Optionally, referring back to diamond 1218, the user may select to not print the desired shapes which concludes the method 1200 at end block 1220. If the user selects to print the desired shapes, the method 1200 proceeds to block 1222.

[0083] At block 1222, the method 1200 continues by inputting the selected shape file for printing into a slicing and nesting program to generate a geometric code (g-code), as would be understood by one skilled in the art. It is to be understood, that various commercial slicing and nesting programs may be available, such as Desktop Metal®, Markforged®, or other programs provided by Hewlett-Packard (HP®) or General Electric (GE®), as would be further understood by those skilled in the art. The generated g-code may be used to guide printing equipment, for example, a metal CNC printer, to three dimensionally render the shape desired. At block 1224, the g-code may be provided to the printer to 3D print the shape selected from diamond 1218.

[0084] After the component is printed, the method 1200 may perform quality check at diamond 1228 to verify satisfactory printing components. If the quality check is unsatisfactory, the printed component, or part, may be recycled at block 1230. If the quality check is satisfactory, the printed component may be sent to block 1232, which may be a distribution unit 1318, for shipping, storage, or order fulfillment. The method 1200 may then conclude at end block 1220.

[0085] As discussed above, FIG. 13 is a simplified diagram illustrating a control system 1300 for managing data for generation and handling of unique shapes, according to one embodiment of the disclosure. To facilitate understanding, connectivity descriptions and technology utilized by the controller 126 is equally applicable to the connectivity descriptions and technology utilized by the controller 1302. For example, the controller 1302 may contain, and be in signal communicationwith, one or more processors, such as processor 1304, which may be in communication with memory 1306. Stored within the memory 1306 may be software programs such as a unique shape generator sequence module 1308 that when executed by a processer, is operable to generate unique shapes, as discussed below. Additionally, the memory 1306 contain a ledger module 1310 and a quality control module 1312. The controller 1302 may also be in signal communication with a user interface 1314, a printer 1316, or a distribution unit 1318.

[0086] The user interface 1314 may be utilized to communicate inputs, such as inputs from block 1202 and 1204, to the controller 1302. The user interface 1314 may be, for example, a computer screen, a handheld device, or the like, as would be understood by those skilled in the art. The user interface 1314 may communicate with the controller 1302 that governs the unique shape generator sequence module 1308 stored within memory 1306. The memory 1306 may contain a computer- readable medium storing instructions that, when executed by the processor 1304, cause it to perform a specified method, such as method 1200, or a portion of the method 1200, for example.

[0087] The controller 1302 may send instructions, files, or data, to the printer 1316 for printing components as discussed at block 1222 of FIG. 12. Additionally, the printer 1316 may provide data that the instructions, files, or data, was received or is being processed by the printer 1316. In some examples, sensors (not illustrated) within the printer may provide data to the controller 1302, as discussed above.

[0088] The distribution unit 1318 may be in signal communication with the controller 1302. The distribution unit 1318 may contain a shipping unit 1320, a storage unit 1322, or an order fulfillment unit 1324. In one example, after the selected shape is printed via block 1226, the component produced may be shipped to, or stored for, an end user. Either of these units may communicate with an order fulfillment unit 1324 to verify the end user desired shapes are shipped, stored, or handled otherwise, per their request.

[0089] The ledger module 1310 may be utilized to log and store shape files, as discussed in block 1214. The shape files may be of various data sizes, depending on the complexity of the guidelines input, via block 1204. The unique shape files logged within the ledger module 1310 may be stored indefinitely or may be retained for a desired time duration requested per end user. The ledger module 1310 may contain a database that may be sorted, searched, or indexed, based on end user’s unique serial numerals associated to the unique shape files, or both the unique serial numerals and the unique shape file names.

[0090] The quality control module 1312 may be an internal program to verify if conditions are satisfied, such as operations at diamonds 1208 or 1228, for example. The quality control module 1312 may be redundant to guidelines or input parameters but may nevertheless control quality of the operations performed, thereby to reduce, substantially eliminate, or prevent, a risk of software glitch, or hallucinations (should artificial intelligence be applied to any of the operations of method 1200).EXPERIMENTS AND EXAMPLES

[0091] The below experiments are presented to provide experimental pull testing data for the fasteners discussed above.

[0092] Experiment: Pull testing data was performed on the fasteners 300, as discussed above. The experiment selected a random lot of fasteners and divided the quantity in two portions. The first portion was subjected to Test 1 and the second portion was subjected to Test 2. Each test recorded the results at two points of failure. The first point of failure, or the “Initial Stop”, was defined as the first visual structural failure of the truncated conical flare 348 of the upper portion 310 of the fastener 300 visually compressing or bending out of shape when a pulling force was applied in a direction opposite the eyebolt in inch-pound units (“in / lbs”). The second point of failure, or the “Final Stop” was defined as the force required for total structural failure. The test results are shown below in the respective sections.Test 1: The first portion of fasteners were mated with an eyebolt and torqued to about 3-foot pounds (“ft / lbs”) prior to testing. Table 1 below illustrates the results of Test 1.Table 1. Analysis Results of the Pull Force Test on Fasteners from Test 1.Test 2: The second portion of fasteners were also mated with an eyebolt but were over torqued to exceed about 5 ft / lbs prior to testing. Table 2 below illustrates the results of Test 2.Table 2. Analysis Results of the Pull Force Test on Fasteners from Test 2.

[0093] In some experimental tests, the eyebolt was the common failure point initiating the recording of the final stop. However, it was noted that eyebolt separation only occurred after the initial stop data recording and during the continuation of the pull seeking the total structural failure recorded as the final stop. In other experimental tests, the fastener structurally failed mid-shaft.
