A Radio Frequency Identification (RFID) tag is a type of electronic identification device that may be used to identify and track various objects. In practice, an RFID tag is attached to an object, and an RFID reader senses the presence and identifying information associated with the RFID tag. The RFID reader may be located at an entrance or exit of an environment, thus facilitating the tracking and identifying of objects having RFID tags that enter or exit the environment.
RFID tags may be added to existing objects so that they may be tracked. To this end, an RFID tag may be mounted to the exterior of an object using adhesives or shrink wrap. However, by being mounted to the exterior of an object, the RFID tag may impede the intended functionality of the object. For example, if an RFID tag were mounted to the exterior of a socket tool, the socket tool may not be able to fit into tight spaces due to the increased size of the tool created by the added RFID tag. Additionally, retrofitting a tool with an RFID tag may be visually unattractive.
In order to overcome these obstacles, some objects may be manufactured to incorporate an RFID tag. However, it may be expensive to replace existing objects with new RFID-enabled objects. For example, a mechanic shop may have a huge inventory of socket tools. Replacing the huge inventory of existing tools with new RFID-enabled tools may be expensive and impractical.
Many aspects of the present disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
In accordance with the present disclosure, existing inventory items, such as but not limited to, socket tools, air tool fittings, driver bits (e.g., Phillips bits, flathead bits, hex-head bits, TORX® bits, APEX® bits, etc.) allen wrenches, hoses, welding equipment, medical equipment, or any inventory item having a universal attachment fitting, may be retrofitted to become RFID-enabled while maintaining the intended functionality of the inventory items. In general, the present disclosure is directed towards permanently attaching an adapter equipped with an electronic identification device to an inventory item. As used herein, the term “permanently attached” refers to an attachment that is not intended to be removed, unless defeated by component failure, unauthorized removal, or other types of unintended activity. As a non-limiting example, one end of an adapter equipped with an RFID tag is configured to permanently attach to one or more inventory items, such as a socket, a conventional socket adapter, a crowfoot wrench, etc., while the other end of the adapter is configured to removably attach to a socket driver. As such, the adapter, RFID tag, and socket may be a substantially unitary piece. By being configured to permanently attach to a universal attachment fitting, one adapter style may be produced that is capable of permanently attaching to multiple sizes and styles of sockets.
With the RFID enabled adapter permanently attached to a socket or other type of inventory item, an RFID reader may identify or track the inventory item by sensing signals emitted from the RFID tag. For example, an RFID tag reader may be installed at an entrance or exit of an environment, and the activity associated with the inventory item may be monitored. This monitoring may be especially useful, for example, in operating rooms where it is extremely important to track medical tools, in mechanical environments where a lost tool may cause damage to equipment, in an environment where inventory item theft may be a concern, or in other environments. In the following discussion, a general description of the apparatus and its components are provided, followed by a discussion of the operation of the same.
With reference to
In the embodiment shown, the inventory item 101 is embodied in the form of a socket. It is understood that in alternative embodiments, the inventory items 101 may be, for example but not limited to, socket tools, air tool fittings, driver bits (e.g., Phillips bits, flathead bits, hex-head bits, TORX® bits, APEX® bits, etc.) allen wrenches, hoses, welding equipment, medical equipment, or any inventory item having a universal attachment fitting. The adapter 100 may also be preconfigured to be attached to another inventory item 101 or tool such as, for example, a preexisting fitting of a powered or manual driver tool (not shown).
The adapter 100 includes an adapter body 103, an adapter cover 106, an RFID tag 109, an insert 113, one or more retaining elements 116, and possibly other components not discussed in detail herein. The adapter cover 106 surrounds a portion of the adapter body 103 and secures the RFID tag 109 to the adapter body 103. The adapter cover 106 may be transparent to radio frequency energy to facilitate the RFID tag 109 transmitting and/or receiving signals.
The retaining elements 116 are disposed at least partially within the adapter body 103 and facilitate retaining the adapter 100 to an inventory item 101, as will be described later. The insert 113 is also disposed at least partially within the adapter body 103 and extends along a longitudinal axis of the adapter body 103. As will be described later, the insert 113 may extend the retaining elements 116 to facilitate permanent attachment of the adapter 100 to the inventory item 101.
Turning to
As will be described below, in the embodiment shown, the male end 119 is configured to permanently attach to the inventory item 101, while the female end 123 is preconfigured to attach to, for example, a male end of a socket driver tool or other type of powered or manual tool (not shown). It is understood that although the embodiment shown has a male end 119 and a female end 123, both ends may be male or both ends may be female in alternative embodiments.
Although shown in
The adapter body 103 may also include a groove 126, a recess 129, an orifice 133, one or more bores 136, an edge 139, a rim 143, and possibly other features not discussed in detail herein. The groove 126 extends at least partially circumferentially around the adapter body 103. The recess 129 is a depressed region of the adapter body 103 and may take a shape that is slightly larger than the RFID tag 109 or a holder of the RFID tag 109.
The orifice 133 extends longitudinally from the male end 119 to the female recess 124. In alternative embodiments, the orifice 133 may not extend completely to either one of the ends. The one or more bores 136 extend from an outer surface of the male end 119 to the orifice 133 and are configured to receive the retaining elements 116 (
The edge 139 may be a surface configured to be adjacent to the inventory item 101. The rim 143 may be disposed along the adapter body 103 towards the female end 123. Both the edge 139 and rim 143 may facilitate attaching and retaining the adapter cover 106 to the adapter body 103 as will be described later.
With reference now to
The adapter cover 106 includes an interior surface 145 extending through the adapter cover 106 for at least a portion of the adapter body 103 to pass through the adapter cover 106. In various embodiments, the adapter cover 106 may be constructed of nylon or other plastic-type materials to facilitate transmission of signals to and from the RFID tag 109. However, it is understood that the adapter cover 106 may be constructed of other materials that are transparent to radio frequency energy.
The adapter cover 106 may also include a lip 146, one or more detents 149, a receptacle 153, and possibly other features not discussed in detail herein. The lip 146 extends from an interior surface at an end of the adapter cover 106. Although shown in
The one or more detents 149 are disposed on the interior surface 145 of the adapter cover 106. Although shown in
The receptacle 153 includes a frame 154 extending from the interior surface 145 of the adapter cover 106 and a pocket 155 configured to receive the RFID tag 109. The receptacle 153 may aid in aligning the adapter cover 106 with the adapter body 103 during assembly of the adapter 100. Further, the receptacle 153 may provide cushioning or protection for the RFID tag 109.
Referring back to
The retaining element 116 facilitates permanently attaching the adapter 100 to the female fitting 102 of the inventory item 101. In the embodiment shown, the retaining element 116 is embodied in the form of a ball. In alternative embodiments, retaining members such as prongs, barbs, tabs, ears, snaps, cylinders, fins, or any other types of retaining elements 116 may be used. Additionally, it is noted that one or more retaining elements 116 may be used in various configurations.
In the embodiment shown in
The insert 113 may be configured to extend and stake the retaining elements 116 from the retracted position to the locking position. As shown in
Next, a description of the operation of the various components of one example, among others, of the adapter 100 is provided. Turning to
In order to assemble the adapter 100, the RFID tag 109 may be placed in the receptacle 153 of the adapter cover 106, and the adapter cover 106 may be slid over the adapter body 103. The detents 149 (
In a similar fashion, the recess 129 of the adapter body 103 and receptacle 153 of the adapter cover 106 facilitate proper rotational alignment of the adapter body 103 with respect to the adapter cover 106. Because the recess 129 is configured to accommodate the shape of the receptacle 153, proper rotational alignment during assembly is apparent during assembly. Additionally, the adapter cover 106 may be prevented from rotating after assembly.
The retaining elements 116 may be placed in the bores 136 of the adapter body 103, and the inventory item 101 may be placed on the appropriate end of the adapter body 103. As best shown in
The insert 113 may be inserted into the orifice 133 of the adapter body 103. The insert 113 may be driven or forced into position using, for example, a hammer or other method. By driving the insert 113 into the orifice 133, the retaining elements 116 are extended from a retracted position to a locking position by engaging the retaining element 116 receiving portions 156. Friction between the insert 113 and the orifice 133 retains the insert 113, and thus the retaining elements 116, in the locking position. With the retaining elements 116 engaging the receiving portions 156, the adapter 100 may be permanently attached to the inventory item 101.
Turning now to
The adapter cover 106, RFID tag 109, adapter body 103, and inventory item 101 are similar to as is described above. However, in the embodiment shown, a retaining ring 166 facilitates permanent attachment of the adapter 100 to the inventory item 101. The retaining ring 166 may comprise a rigid material, for example, and includes an inner edge 169 and an outer edge 173.
The male end 119 of the adapter body 103 now includes a groove 176 configured to accommodate the inner edge 169 of the retaining ring 166. The female fitting 102 of the inventory item 101 also includes a groove 179 configured to receive the outer edge 173 of the retaining ring 166.
In order to permanently attach the adapter 100 to the inventory item 101, the RFID tag 109 and adapter cover 106 may be attached to the adapter body 103 as previously described. Additionally, the retaining ring 166 may be slid over the male end 119 of the adapter body 103, with the inner edge 169 of the retaining ring 166 fit into the groove 176 of the male end 119. Thereafter, the male end 119 of the adapter body 103 and the retaining ring 166 may be inserted into the female fitting 102 of the inventory item 101. The outer edge 173 of the retaining ring 166 may insert into the groove 179 in the female fitting 102 of the inventory item 101. The retaining ring 166, in conjunction with the groove 179 in the inventory item 101 and the groove 176 in the male end 119 of the adapter body 103, may thereby prevent the inventory item 101 from being removed from the adapter 100. Thus, the adapter 100 may be permanently attached to the inventory item 101.
Turning now to
The adapter cover 106, RFID tag 109, adapter body 103, and inventory item 101 are similar to as described above. In the embodiment shown in
Additionally, the adapter 100 includes an O-ring 189. The O-ring 189 may comprise a flexible material (e.g., rubber) that is capable of stretching, compressing, etc. The groove 176 in the male end 119 may accommodate the O-ring 189 and a portion of the retaining ring 166. Likewise, the groove 179 in the inventory item 101 may accommodate a portion of the retaining ring 166 as will be described.
In order to permanently attach the adapter 100 to the inventory item 101, the RFID tag 109 and adapter cover 106 may be attached to the adapter body 103 as previously described. Additionally, the O-ring 189 may be slid (or rolled) over the rounded nose 181 of the male end 119 of the adapter body 103 and fit into the groove 176 in the male end 119.
Thereafter, the retaining ring 166 may be placed over the O-ring 189 in the groove 176 of the male end 119. Then, the male end 119 of the adapter body 103 may be inserted into the female fitting 102 of the inventory item 101. By the male end 119 being inserted into the female fitting 102, the inventory item 101 may compress the retaining ring 166, thereby reducing the size of the gap 183. In turn, the retaining ring 166 may compress the O-ring 189.
Once the outer edge 173 of the retaining ring 166 is aligned with the groove 179 in the inventory item 101, the retaining ring 166 may expand due to internal forces of the retaining ring 166 and/or force exerted from the O-ring 189. In turn, the outer edge 173 of the retaining ring 166 is forced into the groove 179 of the inventory item 101. Because of internal forces of the retaining ring 166 and/or force from the O-ring 189, a portion of the retaining ring 166 is disposed within both the groove 176 of the adapter body 103 and the groove 179 of the inventory item 101. Thus, the adapter 100 may be permanently attached to the inventory item 101. Further, it is noted that a chemical adhesive or other material may be placed on the male end 119 and/or female fitting 102 prior to attachment, in order to prevent vibration of the adapter 100 with respect to the inventory item 101.
The adapter 100 may be permanently attached to the inventory item 101 using various other techniques. In other embodiments, thermal expansion characteristics of various components may be exploited in order to permanently attach the inventory item 101 to the adapter 100. To this end, the materials forming the inventory item 101, the adapter body 103, the insert 113, the retaining elements 116 and/or other components may be selected so as to allow assembly with the components under heat or cold. While under the heat or cold, the various components may contract or expand, thereby facilitating the inventory item 101 being placed on (or in), the adapter 100. By removing the heat or cold, the components of the adapter 100 and/or inventory item 101 may expand or contract to their normal sizes, thereby creating a permanent attachment.
In various embodiments, a press pin or other type of fastener may extend through both the inventory item 101 and the adapter 100, thereby permanently attaching the inventory item 101 to the adapter 100. Also, alternative embodiments may be permanently attached using, for example, locking threads, adhesives, bonding agents, etc.
Further alternative embodiments include the use of deformable components. For example, instead of using a retaining element 116, a deformable element may be extended through the bores 136 by a force, causing the deformed element to permanently retain the inventory item 101. Other deformable components may be used as well.
With reference now to
One or more tab receptacles 199a-199b may be disposed in the ends 203a-203b of the second cover section 106b. The tab receptacles 199a-199b may be configured to receive and permanently retain the tabs. To this end, the prongs 196 of the tabs 193 may engage corresponding shoulders 197a-197b within the tab receptacles 199a-199b. It is further noted that in various other embodiments, one end 203a of the second cover section 106b may be joined to the first cover section 106a, for example, by a hinge or other component.
When attaching the adapter cover 106 to the adapter body 103, the RFID tag 109 (
