DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0106] The present invention will be described in relation to various illustrative embodiments. It shall be understood that the scope of the invention encompasses all combinations and sub-combinations of the features of the embodiments disclosed herein.

[0107] As described herein, when two or more parts or components are described as being connected, secured or coupled to one another, they can be so connected, secured or coupled directly to each other or through one or more intermediary parts.

[0108] In the context of the present invention, the expressions pallet module and pallet assembly are understood to refer to self-supporting platforms configured to allow the handling and transportation of goods, as used in particular for freight logistics, warehousing, transport and/or shipment purposes. Other similar purposes may also come into consideration, including e.g. intralogistics, namely the logistical handling of goods within the walls of a production or distribution center. More specifically, a pallet assembly according to the invention is built of multiple pallet modules which are nested within and interlock with one another to form a platform that is adapted in particular to support and allow transport and shipment of goods or equipment, be it by ground, sea or air transportation.

[0109] The invention will be described in relation to various embodiments of a modular pallet architecture (or modular pallet system) comprising a plurality of pallet modules that can selectively be assembled one with the other to form pallet assemblies of varying configurations and sizes. The modular pallet architecture disclosed herein is preferably based on the modular pallet concept disclosed in International (PCT) Publications Nos. WO 2020/141492 A1 and WO 2020/141494 A1, but it will be appreciated that the present invention is in effect applicable to any modular pallet architecture that would provide similar modularity and benefits.

[0110] As far as the configuration and physical interconnection of the pallet modules are concerned, one may accordingly refer to the previous discussion of FIGS. 1A-B to 5, which is of direct relevance, and to the full disclosure of International (PCT) Publications Nos. WO 2020/141492 A1 and WO 2020/141494 A1, which publications are incorporated herein by reference. Ideally, each pallet module includes, as shown e.g. in FIGS. 1A-B to 5, (i) a mating system configured to allow nesting of another pallet module to form the nested pallet assembly, and (ii) a securing system configured to allow the pallet module to be secured to or released from another pallet module of the nested pallet assembly. The interconnectable pallet modules may once again be of different sizes.

[0111] FIGS. 6A to 6D are various schematic illustrations of modular pallet assemblies, generally designated by reference numeral 1000, in accordance with embodiments of the invention. Each pallet assembly of the invention, including the illustrated pallet assemblies 1000, is in effect built of multiple pallet modules (e.g. pallet modules 10, 20, 30 generally having the configurations shown and discussed with reference to FIGS. 1A-B to 5). For the sake of illustration, all embodiments shown are based on a pallet assembly configuration that is similar to that of the pallet assembly 1000 shown in FIG. 5. That is, each of the pallet assemblies 1000 depicted in FIG. 6A-D is formed of five unit-size pallet modules 10 and one medium-size pallet module 20 that are assembled together to form a square-shaped pallet assembly. It is of course to be understood and appreciated that this is a purely illustrative assembly and that any other possible combination of pallet modules 10, 20 and/or 30 could be contemplated.

[0112] In accordance with the invention, at least two types of pallet modules are to be distinguished, namely so-called primary pallet modules and secondary pallet modules. These modules are also respectively called active pallet modules and passive pallet modules.

[0113] All embodiments of the pallet assembly 1000 depicted in FIGS. 6A-D share a common denominator, namely the fact that at least one of the pallet modules (highlighted in grey in FIGS. 6A-D) is designed as active, primary pallet module, designated by reference sign P (or P.sub.A, P.sub.B in FIG. 6D), which comprises primary hardware HW1 (or HW1A, HW1B in FIG. 6D) configured to actively handle and manage at least one primary functionality of the entire pallet assemble 1000. The primary pallet module P, P.sub.A, resp. P.sub.B, in effects acts as a master module (i.e. the brain of the relevant pallet assembly), and the remaining pallet modules forming the pallet assembly 1000 delegate the relevant primary functionality to the primary pallet module P, P.sub.A, resp. P.sub.B. In practice, each primary pallet module may be marked, coloured or differentiated in any other appropriate way to facilitate identification thereof and distinguish it from other, non-active pallet modules.

[0114] For instance, FIG. 6A schematically depicts an embodiment where the primary functionality that is actively handled and managed by the primary hardware HW1 includes provision of wireless connectivity to and long-range communication with at least one remote station. In this first embodiment, the remaining five pallet modules are functionally inactive modules, designated by reference sign I, with no particular hardware or added functionality beyond the ability to physically interconnect with other pallet modules.

[0115] FIG. 6B schematically depicts another embodiment where the primary functionality that is actively handled and managed by the primary hardware HW1 includes active control and/or monitoring of humidity, which may be necessitated in the event the goods or material to be loaded onto and shipped along with the pallet assembly 1000 require(s) humidity conditions to remain within acceptable tolerances. In this other embodiment, the remaining five pallet modules are passive, secondary pallet modules, designated by reference sign S, with no particular hardware but possibly added functionality designed to supplement or enable part of the active control and/or monitoring of humidity. In this context, each of the pallet modules P, S forming the pallet assembly 1000 may for instance include humidity insulation designed to assist humidity control, and prevent e.g. humidity from seeping through the pallet assembly. The primary hardware HW1 may in effect actively handle and manage any other primary functionality or combination of functionalities, including e.g active control and/or monitoring of refrigeration.

[0116] FIG. 6C schematically depicts a particularly advantageous embodiment where the primary functionality that is actively handled and managed by the primary hardware HW1 includes provision of wireless connectivity to and long-range communication with at least one remote station, as well as wireless local interconnectivity amongst the pallet modules forming the pallet assembly 1000. In this case, the remaining five pallet modules are passive, secondary pallet modules S comprising secondary hardware HW2 configured to wirelessly interconnect with the primary hardware HW1 of the primary pallet module P. In this case also, the primary pallet module P acts as master module handling the aforementioned primary functionality of the entire pallet module 1000, while the secondary modules S supplement and enable part of this primary functionality, as this will be detailed hereafter.

[0117] One will once again appreciate and understand that the primary hardware HW1 may in effect actively handle and manage any desired combination of functionalities. Furthermore, any given pallet assembly may include more than one primary module each comprising primary hardware configured to actively handle and manage a dedicated primary functionality of the entire pallet assembly. FIG. 6D for instance schematically depicts an embodiment of a pallet assembly 1000 including two primary modules P.sub.A, P.sub.B each comprising hardware HW1.sub.A, HW1.sub.B handling a dedicated primary functionality, for instance active control and/or monitoring of humidity and, respectively, local as well as long-range wireless interconnectivity.

[0118] The modular pallet assembly of the invention may be used as part of a modular crating or boxing system. FIGS. 7A and 7B for instance schematically show two embodiments of a closed box comprising a pallet assembly 1000 in accordance with the invention physically interconnected with wall members W and a closed by a top cover member T.

[0119] More specifically, FIG. 7A schematically shows such a solution applied to a refrigerated closed box as used for instance for shipment of goods necessitating a cold chain. In this context, the primary hardware HW1 may include hardware to provide a refrigerant, in which case each of the pallet modules (as well as the wall members W and top cover member T) include added thermal insulation. For such an application, the pallet assembly 1000, wall members W and top cover member T are in effect designed to maintain a controllable environment inside the close box with respect to temperature (and possibility humidity). In the illustrated example, the primary hardware HW1 further handles and manages, in addition to refrigeration, wireless connectivity to and long-range communication with at least one remote station.

[0120] In the illustrated example, one will appreciate that the wall members W and top cover member T are each advantageously configured to supplement or enable part of the primary functionality (here refrigeration) of the pallet assembly 1000, much like the secondary pallet module S.

[0121] If necessary, the wall members W and top cover member T may further comprise dedicated hardware configured to interact with the hardware of the pallet assembly 1000, namely hardware HW1 of primary pallet module P.

[0122] It will be appreciated that monitoring of refrigeration does not necessarily require a close box configuration as shown in FIG. 7A. The pallet assembly 1000 itself may be stored inside a refrigerated container, in which case the primary hardware HW1 only requires means to monitor temperature and check that the cold chain has not been broken.

[0123] FIG. 7B schematically illustrates that the wall members W and top cover member T could likewise be constructed as modular elements to provide even greater flexibility as regards configuration of the box.

[0124] FIG. 8 is a schematic illustration of a data collection and management system in accordance with an embodiment of the present invention, comprising a data collection and management server SRV, preferably a cloud-based server, in wireless, long-range communication with a pallet assembly 1000. FIG. 8 further shows a workstation WRK in operative communication with the data collection and management server SRV, which workstation WRK may especially be configured to run suitable software to manage and process data collected by the data collection and management server SRV.

[0125] While only one pallet assembly 1000 is depicted in FIG. 8, it will be appreciated and understood that the data collection and management server SRV is in effect in long-range communication with a plurality of geographically distributed pallet assemblies.

[0126] In accordance with a preferred embodiment of the invention, as illustrated in FIG. 8, each pallet assembly includes a minimum of one primary pallet module P that is physically interconnected with one or more secondary pallet modules S. In the illustrative example of FIG. 8, pallet assembly 1000 is shown as comprising one such primary pallet module P (highlighted in grey)namely unit-size pallet module 10 in the upper left cornerand five such secondary pallet modules S-namely four unit-size pallet modules 10 and one medium-size pallet module 20.

[0127] The primary and secondary pallet modules P. S differ in terms of functionality and hardware. The primary pallet module P once again acts as master module (i.e. the brain of the relevant pallet assembly) and comprises primary hardware HW1 configured to actively handle and manage at least one primary functionality of the relevant nested pallet assembly of which it forms a part. By contrast, each secondary pallet module S comprises no hardware or limited hardware merely configured to supplement or enable part of the primary functionality of the pallet assembly that is actively handled and managed by the primary hardware HW1.

[0128] In accordance with the preferred embodiment shown in FIG. 8, the secondary pallet modules S each comprise secondary hardware HW2 that is configured to supplement or enable part of the relevant primary functionality that is actively handled and managed by the primary hardware HW1.

[0129] In the illustration of FIG. 8, the primary functionality handled by the primary hardware HW1 includes provision of wireless connectivity to and long-range communication with at least one remote station (namely data collection server SRV and workstation WRK), as well as of wireless interconnectivity amongst the pallet modules forming the nested pallet assembly 1000. More specifically, the primary hardware HW1 is not only configured to establish a wireless connection to and long-range communication with the remote station SRV, resp. WRK, but further configured to provide wireless interconnectivity with other pallet modules of the nested pallet assembly 1000, namely the five secondary pallet modules S shown in FIG. 8. In this context, the secondary hardware HW2 supplements and enables the primary functionality of the nested pallet assembly 1000 by being configured to wirelessly interconnect with the primary hardware HW1.

[0130] In the illustrated embodiment, the sole purpose of the secondary hardware HW2 is to enable wireless local interconnectivity with the primary hardware HW1. The secondary hardware HW2 does not as such play a direct role in the wireless connectivity to and long-range communication with the remote server SRV, which functionality is handled by the primary hardware HW1 of the primary pallet module P.

[0131] By way of preference, wireless interconnection between the primary and secondary pallet modules P. S forming the nested pallet assembly 1000 is ensured by establishing a short-range communication between the primary hardware HW1 and secondary hardware HW2 using radio-frequency identification (RFID) or Bluetooth Low Energy (BLE) technology. RFID technology is preferred in that the secondary hardware HW2 may in essence simply consist of an active or semi-active RFID tag (including onboard battery) or passive RFID tag (without any onboard battery) energized by a radio-frequency interrogating signal produced by a short-range wireless communication interface (or RFID reader) forming part of the primary hardware HW1.

[0132] FIG. 9 is a schematic illustration of the hardware HW1, HW2 of FIG. 8 in accordance with a preferred embodiment of the invention. Primary hardware HW1 includes at least a source of energy 950, such as battery, to supply energy to the primary hardware HW1 and a processing unit or controller 900 configured to control operation of the primary hardware HW1. Primary hardware HW1 further includes a long-range communication interface 910 configured to communicate with a remote station (including e.g. the remote, cloud-based server SRV of FIG. 8) and a short-range wireless communication interface 920 configured to established a wireless local connection with the secondary hardware HW2.

[0133] In the illustrated example, the secondary hardware HW2 merely includes a short-range communication device 990 configured to wirelessly communicate with the short-range wireless communication interface 920 of the primary hardware HW1, which short-range communication device 990 consists of an RFID device, namely a passive RFID tag that is energized by a radio-frequency (RF) interrogating signal produced by the short-range wireless communication interface 920 of the primary hardware HW1. Three such RFID tags 990 are depicted in FIG. 9 for the sake of illustration, it being however understood that one RFID tag is in practice associated to each one of the secondary pallet modules S forming the relevant pallet assembly.

[0134] The short-range communication devices 990 could in effect be any suitable communication device capable of communicating with the wireless communication interface 920 over a short distance sufficient to cover the pallet assembly. Other technologies than RFID technology may therefore come under consideration, including e.g. Bluetooth Low Energy (BLE) technology.

[0135] As already mentioned, each short-range communication device 990 may be selectively interrogatable by means of an external reader device, for instance by an operator to carry out e.g. selective on-site interrogation of the relevant pallet modules in case of need.

[0136] In the illustrated example, the secondary hardware HW2 is primarily configured to communicate a unique identifier to the primary hardware HW1 which uniquely identifies each secondary pallet module S. In other words, the primary hardware HW1 will receive and be able to process information identifying which pallet modules are constitutive of the relevant pallet assembly. The primary hardware HW1 may be configured to periodically trigger the secondary hardware HW2 to communicate the unique identifier.

[0137] Each primary module may similarly include some ability to establish a short-range communication channel with an external communication device, such as a smartphone, tablet or the like. Any appropriate technology may come under consideration, including e.g. Near-Field Communication (NFC) technology. NFC technology is favoured in that it allows fast and secure connection to the primary hardware HW1.

[0138] The long-range communication interface 910 preferably includes a cellular transceiver configured to establish a suitable connection with the remote station via a cellular network CN. The cellular transceiver 910 may in particular be configured to establish a cellular connection with the cellular network CN based on a Low Power Wide Area Network (LPWAN) standard, such as the LTE-M (Long-Term Evolution for Machines) standard (including the enhanced Machine Type Communication, or eMTC, standard), the NB-IoT (Narrowband Internet of Things) standard, or the EC-GSM-IoT (Extended Coverage GSM Internet of Things) standard. These LPWAN standards have been developed by the 3.sup.rd Generation Partnership Project (3GPP-www.3gpp.org) and are established standards for the Internet of Things (IoT). By adopting these standards, each primary pallet module P is in effect turned into an IoT-enabled pallet module which allows e.g. identification and tracking of each primary pallet module P and thus of each pallet assembly of which it forms a part.

[0139] As shown in FIG. 9, the primary hardware HW1 may further include at least one geolocalization device 930 configured to ascertain a geographical position of the primary pallet module P, and thus of the nested pallet assembly comprising the said primary pallet module P. This geolocalization device 930 may in particular be a satellite position device, such as a GPS device. The geographical position may be communicated back to the remote station via the aforementioned long-range communication link.

[0140] As a further refinement, the primary hardware HW1 may additionally include one or more sensors 940 and/or one or more dedicated sensor interfaces 945 connectable to sensors configured to sense at least one physical or environmental parameter, such as temperature, pressure, humidity, acceleration, or inertial or angular momentum. In other words, the primary functionality of the primary hardware HW1 may potentially be expanded to include and implement additional functionalities, such as e.g. temperature and/or humidity monitoring and/or control.

[0141] The data collection and management system of the invention may especially be configured to collect data about and provide update regarding a status of the pallet assemblies 1000 including: [0142] a load status indicative of whether each pallet assembly 1000 is fully or partially loaded with material or goods or fully unloaded; [0143] a transit/storage status indicative of whether the pallet assembly 1000 is in transit or in a stored location; and [0144] an assembly status indicative of whether the pallet assembly 1000 is assembled or disassembled.

[0145] The data collection and management system may advantageously be further configured to collect data about individual pallet modules and their assembly status.

[0146] In other words, further layers of information are possibly contemplated, namely status information relating to the assembly status of each pallet assembly and, potentially, of each individual pallet module. This status information could be entered manually by an operator and stored in each relevant primary pallet module for communication to the remote station. In other embodiments, the assembly status could be compiled by each primary pallet module in a semi-automatic or automatic manner depending on which pallet modules are located in the immediate vicinity of the primary pallet module (which requires wireless local interconnectivity amongst the pallet modules forming the pallet assembly).

[0147] The invention further generally relates to a process of collecting status data relating to a status of modular pallet assemblies 1000 each consisting of a plurality of physically interconnected pallet modules configured to nest one within another, including: [0148] a load status indicative of whether each pallet assembly 1000 is fully or partially loaded with material or goods or fully unloaded; [0149] a transit/storage status indicative of whether the pallet assembly 1000 is in transit or in a stored location; and [0150] an assembly status indicative of whether the pallet assembly 1000 is assembled or disassembled,

[0151] the status data of any given pallet assembly 1000 being first collected locally in a dedicated pallet module of the pallet assembly 1000 and then communicated to a remote data collection system (i.e. the aforementioned cloud-based server SRV and associated workstation WRK).

[0152] As already described hereabove, the dedicated pallet module may especially be designed as an active, primary pallet module P comprising primary hardware HW1 configured to provide wireless connectivity to and long-range communication with the remote data collection system, as well as wireless local interconnectivity with other pallet modules of the pallet assembly 1000. In such case, the remaining pallet modules, beyond the primary pallet module P, are passive, secondary pallet modules S comprising secondary hardware HW2 configured to wirelessly interconnect with said primary hardware HW1, and status data relating to the secondary pallet modules S is collected locally by the primary hardware HW1 for communication to the remote data collection system.

[0153] At least part of the aforementioned hardware HW1, HW2 may be embedded into a structural body of the associated pallet module, including e.g. the structural body 100, 200, resp. 300, of the pallet modules 10, 20, resp. 30 shown in FIGS. 1A-B to 3A-B. Especially, passive RFID tags, acting as secondary hardware HW2, may be embedded into the structural body of the associated pallet module at the time of manufacture. By contrast, the primary hardware HW1 may simply be secured or attached to a suitable portion of the pallet module in such a way as to remain accessible and potentially exchangeable.

[0154] Various modifications and/or improvements may be made to the above-described embodiments without departing from the scope of the invention as defined by the appended claims.

[0155] For instance, while not specifically shown, each primary pallet module may likewise be provided with an RFID tag (or like short-range communication device) to provide unique identification of the pallet module. Such RFID tag may be distinct from the primary hardware and embedded e.g. into a structural body of the pallet (much like the secondary hardware), in which case the RFID tag may be interrogated along with the other RFID tags. Alternatively, the RFID tag may be directly interfaced with the primary hardware or the functionality thereof be implemented directly into the primary hardware.

[0156] By analogy, dedicated hardware could also be incorporated into the wall members andif presentthe top cover member of crates or boxes comprising a pallet assembly in accordance with the invention, which dedicated hardware could interact with e.g. the primary hardware of the primary pallet module, much like the secondary hardware of the secondary pallet modules described above. In such case, additional status data could likewise be collected with respect to a status of relevant crates or boxes.
