[0005] Adapter for attaching a display device to a handling unit

[0006] Technical Field

[0007] The invention relates to an adapter for attaching a display device to a handling unit, a display device and a system comprising a handling unit, an adapter and a display device.

[0008] Technological Background

[0009] The European market is estimated to utilize over 4 billion handling units annually, which includes pallets, containers, crates, and other types of transport units. Pallets alone account for a significant share, with around 500 million pallets in active circulation across Europe, including both standardized Euro pallets and various other formats used for shipping and storage.

[0010] Non-digitalized handling units, such as traditional pallets or containers suffer from inefficiencies, such as in tracking and monitoring in the production chain. Without digitalization, companies cannot easily access real-time data on the location, status, or condition of their handling units during transportation and storage. This can lead to delays, misplacement, or even loss of assets, reguiring manual tracking methods that are time-consuming and prone to human error. It also complicates inventory management and impacts supply chain transparency, causing potential bottlenecks.

[0011] Manual processes in non-digitalized handling units increase costs and are particularly damaging to the environment because a significant amount of paper is used. Handling units must be manually inspected and managed, which slows down operations in warehouses, transport hubs and production chains. Moreover, the inability to automate sorting, tracking, and monitoring tasks increases the likelihood of damaging goods, miscommunications, and costly errors in logistics. This hinders scalability and makes it difficult for businesses to optimize operations, leading to increased maintenance and handling costs.

[0012] However, the digitalization of handling units is accompanied by a number of hurdles. In particular, the sheer number of handling units shows that the digitalization goes along with enormous costs if the handling units would be replaced. Furthermore, the tools to manufacture the handling units shall Applicant: VusionGroup GmbH

[0015] Date: October 15, 2024 not be changed, as the manufacturing processes are already well-established and reliable. Therefore, an alternative solution is required that is compatible with existing handling units and existing production processes.

[0016] Summary of the invention

[0017] It is an object of the present invention to provide an adapter for attaching a display device to a handling unit.

[0018] In a first aspect, an adapter for attaching a display device to a handling unit is suggested. The adapter comprises a first attachment portion and a second attachment portion, wherein the first attachment portion comprises a first attachment mechanism, wherein the first attachment mechanism is configured to couple the first attachment portion with the handling unit, wherein the second attachment portion comprises a second attachment mechanism, wherein the second attachment mechanism is configured to couple the second attachment portion with the display device. An adapter is a device or component used to connect two otherwise incompatible parts or systems, allowing them to work together. It modifies or adjusts the mechanical interface between differing equipment to ensure proper fit and function.

[0019] The first attachment portion of the adapter is the specific section or part of the adapter which is designed for connecting or coupling the adapter to the handling unit. In particular, the attachment portion may also comprise optional features to further stabilize the coupling between the adapter and the handling unit. This first attachment portion is typically shaped or constructed to align and secure with the specific shape of the handling unit, such as a mounting point or interface that enables a mechanical connection. The first attachment mechanism is the means or method by which the adapter and the handling unit are coupled or joined or connected. For example, the first attachment mechanism can involve various techniques such as clamps, hooks, clips, magnets, or latches, providing stability and ensuring that the parts remain fastened during operation. In particular, the first attachment mechanism can be designed in such a way that the adapter can be coupled with an already existing handling unit, i.e. the handling unit does not need to be customized to couple with the adapter. This may allow that the production process of the handling units does not need to be adapted. The complete production line of the handling units can remain as is. In particular, the handling units can be either equipped with an adapter or they are not equipped with an adapter, thus allowing the handling unit manufacturer the full flexibility also with view on their customer needs.

[0023] The second attachment portion of the adapter is the specific section or part of the adapter which is designed for connecting or coupling the adapter to the display device. The second attachment portion is typically shaped or constructed to align and secure with the specific shape of the display device, such as a mounting point or interface that enables a mechanical connection. The second attachment mechanism is the means or method by which the adapter and the display device are coupled, joined or connected. For example, the first attachment mechanism can involve various techniques such as clamps, hooks, clips, magnets, or latches, providing stability and ensuring that the parts remain fastened during operation. In particular, the second attachment mechanism can be designed in such a way that the adapter can be coupled with an already existing display device, that is, the display device does not need to be customized to couple with the adapter. This may allow that the production process of the display devices does not need to be adapted. The complete production line of the display devices can remain as is.

[0024] The adapter may be configured for retrofitting and / or fitting the display device to the handling unit. Fitting refers to the process of initially installing or applying or coupling the adapter to make the object compatible with a display device. The installation is done when the handling unit is first being set up or produced. In particular, the installation of the adapter may be a further step in the production process of the handling unit. Retrofitting on the other hand involves modifying, upgrading, or altering an existing handling unit by adding or replacing an adapter after the handling unit has already been in use for some time. Retrofitting is often necessary to meet new standards, accommodate changes in technology, or improve the performance of the handling unit. While fitting is part of the original setup, retrofitting addresses changes needed afterwards, such as maintenance. Thus, retrofitting may refer to the process of adding new technology, features, or systems to existing handling units to improve their functionality, efficiency, or safety. This may be done without replacing or modifying the original components of the handling unit. This may extend the life and functionality of existing handling units while incorporating modern standards or technologies.

[0025] The first attachment portion may be coupled to the handling unit without a mechanical modification of the handling unit. Mechanical modification may refer to the alteration, adjustment, or enhancement of a handling unit to change its performance, function, or compatibility. This may involve physical changes such as reshaping, adding, or removing parts, or changing materials to improve durability, efficiency, or fit. Mechanical modifications are often made to adapt equipment to new requirements, improve functionality, or repair and upgrade existing systems. However, as mechanical modifications may be avoided, this may allow existing handling units to be used together with the adapter. Applicant: VusionGroup GmbH

[0029] The first attachment portion may be coupled to the handling unit without drilling and / or screwing and / or glueing and / or welding and / or riveting. Drilling, screwing, glueing, welding and riveting all influence the structural integrity of the handling unit. Therefore, avoiding these mechanical modification means may allow maintaining the structural integrity of the handling unit.

[0030] At least two sides of the adapter may contact the handling unit at least in part. The adapter typically comprises six sides: The left side, the right side, the top side, the bottom side, the front side and the back side. The back side may refer to the side of the adapter that faces the body of the handling unit. The body of the handling unit is the part of the handling unit that provides the main structural component for the handling of goods. The front side of the adapter is the opposite side of the back side and furthermore shows the display device, if the display device is attached. The other sides are arranged around the adapter. Each of the other sides connects the front side and the back side. For example, the back side of the adapter may be at least partly in contact with the body of the handling unit. In addition, other sides, as for example the top side, may contact the handling unit, if the handling unit contains structural elements protruding from the body of the handling unit and allowing contact with the other sides of the adapter. Such structural elements may be located at the corner of the handling unit. The sides may not provide a full surface contact to the handling unit, but may contact the handling unit at least in part, i.e., at respective contact points. Also, additional sides, as for example, the left and / or right side of the adapter may contact the handling unit at least in part. This may allow stabilizing the adapter in at least two geometrical directions by the handling unit.

[0031] At least one side of the adapter may contact the body of the handling unit at least in part. As explained above, the body of the handling unit is the part of the handling unit that provides the main structural component for the handling of goods. For example, the main structural component of a box is the body of the box that encloses the transportation volume. For example, the main structural component of a pallet is the storage area, where boxes can be stored. However, the main structural component of a pallet can also be the sides which have openings for forklifts or the like, as the main structural component allows for the handling of the pallet.

[0032] The back side of the adapter may contact the body of the handling unit at least in part. For example, the back side of the adapter can rest on or touch the body of the handling unit. This may stabilize the adapter in at least one geometrical direction.

[0033] The first attachment mechanism may be a releasable attachment mechanism, in particular a reusable attachment mechanism. A releasable attachment mechanism provides a mechanical connection between the handling unit and the adapter that allows the components to be joined together se- Applicant: VusionGroup GmbH

[0035] Our ref.: VSG31408PCT

[0036] Date: October 15, 2024 curely and easily separated again without damaging the handling unit. This may allow that the attachment can quickly and easily be disassembled without requiring complex tools or procedures and that the handling unit can further be used after disassembling. Reusable refers to the ability that the adapter may be used with the same handling unit or with a different handling unit after the attachment mechanism is released. In this case, the adapter can be reused with a new handling unit when the previous handling unit is damaged and has to be replaced. This may minimize the maintenance costs.

[0037] The first attachment mechanism may be a non-releasable attachment mechanism, in particular the first attachment mechanism may not be released without destruction. A non-releasable attachment mechanism provides a mechanical connection between the handling unit and the adapter, which is designed to be permanent. In this case, it should not be possible to disassemble the adapter without damaging the coupling or at least one of the components. This may provide a strong, durable, and secure connection, which may ensure a stable and reliable coupling. This may be particularly beneficial in the field of transportation of goods. Also, it may prevent replacing or removing the adapter and / or the connected display device, in case the handling units are not stored in a secure location. As the adapter should be damaged during disassembly, it may also not be reusable. This may provide a unique coupling between the handling unit and the adapter, such that the display device can provide information or measures data that is uniquely connected with the specific handling unit, such as the lifetime of the specific handling unit.

[0038] The first attachment mechanism may be configured to protrude in one or more recesses and / or holes of the handling unit. Protruding in one or more recesses may refer to a design where the first attachment mechanism or a part of the first attachment mechanism extends or juts out into a specifically cavity or indentation or hole within a part of the handling unit. This may enhance the alignment and stability of the coupling between handling unit and adapter, ensuring that the adapter is accurately positioned and securely held in place, reducing the risk of misalignment or movement during handling of the handling unit.

[0039] The one or more recesses of the handling unit are formed by different components of the handling unit, in particular by at least one flap and / or at least one rim and / or a body of the handling unit and / or at least one strut and / or at least one handling unit reinforcement. The body of a handling unit is the main structural component that may hold or enclose contents or goods. The body may form the primary shape of the handling unit and may provide the bulk of its strength and durability. The body of the handling unit is typically made from materials such as plastic or metal or cardboard, depending on the intended use and required strength. Other materials are possible depending on the Applicant: VusionGroup GmbH

[0042] Date: October 15, 2024 intended use. The body of the handling unit may have one or more handling openings such as handles or openings for human hands, pallet trucks or lifting carts and the like. In particular, the handling unit may comprise four side walls and one bottom that form the body of the handling unit. The rim may be an edge or a border that runs around the body of the handling unit. If the handling unit encloses goods, the rim typically runs around the opening of the body of the handling unit and protrudes outwards of the body of the handling unit. As such it may provide a flange around the opening of the body of the box. For example, the rim may be essentially perpendicular to the side wall of the body of the handling unit. The rim may provide structural support to the body of the handling unit. The flap may be a further structural component connected to the outer side of the protruding rim of the handling unit. As such, the flap may form a protruded edge of the handling unit, e.g., by forming an edge substantially parallel to the side walls of the body of the handling unit. For example, the flap is essentially perpendicular to the rim.The flap may also run around the rim of the handling unit. The flap and / or the rim may be structured to provide unhindered access to the handling openings. For example, the flap and / or the rim may have one or more recesses in the area of the one or more handling openings. The strut may be a structural component arranged on the outside of the body of the handling unit. Alternatively or additionally, the strut may be arranged between the rim and / or the flap and / or the body of the handling unit. The strut arranged between the rim and / or the flap and / or the body of the handling unit may at least not substantially influence the outer shape of the handling unit. The strut may provide points of attack for coupling forces, such as clamp or spring forces. The strut may also provide holes to which hooks, pins, tips or clamps can be attached. The handling unit reinforcement, as the strut, may be arranged on the outside of the body of the handling unit and / or between the rim and / or the flap and / or the body of the handling unit. A particular task of the handling unit reinforcement is to stabilize the handling unit such that the handling unit has a higher resistance against mechanical impacts and mechanical loads. The handling unit reinforcement may have different shapes. These components work together to form a functional handling unit, allowing for secure storage, transport, and access to the contents. The components may also form one or more recesses suitable for receiving the first attachment mechanism of the adapter. For example, the flap, the rim and the body of the handling unit may form a recess having a U-shaped cross section. This is for example the case, when the body and the rim as well as the rim and the flap form substantially right angles. One ore more struts and / or handling unit reinforcements may further devide the U-shaped recess into multiple recesses suitable for receiving the first attachment mechanism of the adapter. As the one or more recesses are formed by the handling unit, the first attachment mechanism may be coupled to existing recesses and access points of the handling unit. This may allow that the shape of the handling unit may not be changed, but that existing handling units can be used to couple with the adapter. Applicant: VusionGroup GmbH

[0045] Date: October 15, 2024

[0046] The first attachment mechanism may be configured to protrude in at least one flap and / or at least one rim and / or a body of the handling unit.

[0047] For example, the first attachment mechanism may alternatively or additionally be configured to protrude into at least one recess formed within the flap and / or at least one recess formed within the rim and / or at least one recess formed within the body of the handling unit. A recess formed within the flap, the body or the rim may be a recess which is exclusively formed by the respective part, contrary to a recess formed by the arrangement of the different parts, e.g. U-shape recess, as mentioned above.

[0048] For example, the first attachment mechanism may be configured to protrude into at least one hole formed within the flap and / or at least one hole formed within the rim and / or at least one hole formed within the body of the handling unit. A hole formed within the flap, the body or the rim may be a hole which is exclusively formed in the respective part, i.e. only the respective part is involved in the formation of the hole. Such recesses or holes may provide a point of attack to which a mechanical attachment mechanism can couple. As existing recesses or holes of the body, flap and / or rim are used to attach the adapter, a mechanical modification of the handling units may be avoided.

[0049] The first attachment portion may be configured to be partly covered by the flap of the handling unit and / or the rim of the handling unit when the adapter is coupled with the handling unit. Partly covered by the flap and / or the rim of the handling unit is to be understood as the flap and / or the rim overlapping or extending over a part of the first attachment portion, but not completely. The flap and / or the rim of the handling unit may shield or obscure some areas of the first attachment portion, leaving other areas exposed or visible. This may protect the first attachment mechanism against mechanical impact. Furthermore, the first attachment mechanism may be hidden by the flap and / or the rim, such that the mechanical components may protected against dirt and dust.

[0050] The first attachment portion may be configured to be fully covered by the flap of the handling unit and / or the rim of the handling unit when the adapter is coupled with the handling unit. When the first attachment portion is fully covered, the part of the handling unit completely overlaps or encloses the entirety of the first attachment portion, leaving none of the first attachment portion exposed or visible. The part of the handling unit completely shields, surrounds, or obscures the first attachment portion, so that no portion of the first attachment portion is accessible or visible. This may protect the whole first attachment portion against mechanical impact. Furthermore, the whole first attachment portion can be hidden by the flap and / or rim, such that the mechanical components are protected against dirt and dust. Furthermore, the optical appearance of the handling unit with the adapter may be improved, if only the second attachment portion with the display device is visible. Applicant: VusionGroup GmbH

[0054] The part of the first attachment portion that is covered by the flap of the handling unit and / or the rim of the handling unit may have a reduced thickness compared to the remaining part of the adapter. The thickness refers to the spatial distance between the front side and the back side of the adapter.

[0055] The first attachment portion may protrude partly in one or more recesses formed by or within the flap, the rim and the body of the handling unit, wherein in the first attachment portion may be configured to be partly covered by the flap and / or the rim of the handling unit when the adapter is coupled with the handling unit. For example, the flap, the rim and the body of the handling unit form a U- shaped recess, wherein the flap and the side wall of the body of the handling unit essentially run in parallel to each other, and wherein the rim connects the flap and the side wall of the body of the handling unit. The rim is essentially perpendicular to the side wall of the body of the handling unit and the rim is essentially perpendicular to the flap. Essentially perpendicular may refer to angles formed between the elements between 45° and 100°. The first attachment portion protrudes into one or more of the recesses, when the adapter is attached to the handling unit, so that the one or more recesses enclose and / or contain the first attachment portion. When the flap and / or the rim partly covers the first attachment portion, the flap and / or the rim may extend over the first attachment portion and may hide the first attachment mechanism from direct visual inspection in the coupled state. The flap and the rim may partly cover different sides of the first attachment portion. For example, the rim may cover the upper side of the first attachment portion and the flap may cover the front side of the first attachment portion. This may protect the first attachment portion against mechanical impact. Furthermore, as the one or more recesses enclose or contain the first attachment portion, the mechanical components of the first attachment portion may be protected against dirt and dust. Furthermore, the optical appearance of the handling unit with the adapter may be improved, if only the first attachment portion without the display device but with the mechanical components is covered.

[0056] The first attachment mechanism may be configured to restrict the movement of the adapter in at least one spatial direction, when the adapter is coupled with the handling unit. In at least one direction may refer to the x-, y-, z- directions, but also to rotations around the x-, y- and z-directions. In the frame of the adapter, the spatial directions may also refer to the width-axis or x-axis which extends from the left side to the right side, the height-axis or y-axis which extends from the bottom side to the upper side and the thickness-axis or z-axis which extends from the front side to the back side. In particular, the first attachment mechanism may be configured to restrict the movement of the adapter in z-direction and / or y- direction and / or x-direction, when the adapter is coupled with the handling unit. For example, the adapter may be coupled to the handling unit by moving the adapter in y-direction into a recess of the handling unit. After the coupling, the adapter cannot be moved in Applicant: VusionGroup GmbH

[0057] Title: Adapter for attaching a display device to a handling unit

[0058] Our ref.: VSG31408PCT

[0059] Date: October 15, 2024 y-direction but also not in x- or z-direction. For example, the adapter may be enclosed by the one or more recesses, such that the adapter cannot move in width, height and thickness direction. For example, the shape of the first attachment portion corresponds to the negative form of the one or more recesses, such that both elements form male and female connectors. In addition, such form-fit connection may also prevent a rotation around any axis. This may lock and secure the position of the adapter in the coupled state.

[0060] The first attachment mechanism may be configured to protrude in at least two recesses, wherein protruding into a first recess may restrict the movement of the adapter in a first direction, wherein protruding into a second recess may restrict the movement of the adapter in a second direction, wherein the first and the second direction are different. The handling unit may have different recesses, which are oriented in different directions. Each recess can provide a restriction of the movement in at least on direction. If both directions are different, the protrusion into two different recesses restricts the movement if the adapter in at least two directions. For example, the handling unit can have a first recess, which is oriented in the width direction of the adapter and a second recess, which is oriented in the thickness direction of the adapter.

[0061] The first attachment mechanism may comprise a form-fit attachment mechanism and / or a force-fit attachment mechanism. A form-fit attachment mechanism may rely on the geometric shapes of the connected parts of the handling unit and the first attachment portion fitting together precisely. The parts may be designed with complementary shapes such as grooves, tabs, or other interlocking features. The complementary shapes prevent movement relative to each other when assembled. A form-fit attachment mechanism may provide precise alignment and positioning, ensuring that the first attachment portion and the handling unit are accurately located relative to each other. This is particularly advantageous in applications requiring exact tolerances. A force-fit attachment mechanism, also known as an interference-fit, may refer to an attachment mechanism, where the first attachment portion and the handling unit are joined together by applying force. The first attachment portion might be slightly oversized relative to a corresponding recess in the handling unit, such that the resulting frictional force holds the first attachment portion in place. This type of fit may require pressing or hammering to assemble. A force-fit attachment mechanism may offer strong retention, making the force-fit attachment ideal for applications where components must resist loosening under stress or vibration, such as the transportation business. The form-fit attachment mechanism and the force-fit attachment mechanism are preferably but not necessarily combined.

[0062] The first attachment mechanism may additionally or alternatively comprise a snap-in attachment mechanism and / or a clamp attachment mechanism and or interlocking attachment mechanism. A Applicant: VusionGroup GmbH

[0063] Title: Adapter for attaching a display device to a handling unit

[0064] Our ref.: VSG31408PCT

[0065] Date: October 15, 2024 snap-in attachment mechanism may use flexible components that deform temporarily to allow the first attachment portion to be joined with the handling unit. Once the first attachment portion and the handling unit are assembled, the flexible components of the snap-in attachment mechanism return to their original shape, creating a secure attachment. This often involves the use of clips or tabs or hooks. Snap-in mechanisms may be quick and easy to assemble or disassemble without the need for tools, making them ideal for applications where quick assembly or maintenance is required. A clamp attachment mechanism may use a clamping force to hold two parts together. Clamps can be mechanical devices like levers or other locking mechanisms that apply pressure to secure the parts in place. Clamps may be adjusted to apply varying levels of pressure, allowing for fine-tuning during assembly. This makes them versatile for applications where different forces may be required. An interlocking attachment mechanism may use features on the handling unit and the first attachment portion, such as dovetails, hooks, or other interlocking geometries, to prevent the first attachment portion and the handling unit from separating. The interlocking features mechanically engage when assembled. Interlocking mechanisms may provide strong resistance to movements in multiple directions, making them suitable for applications requiring high stability and structural integrity. The different mechanisms can also be combined depending on the application. For example, the first attachment portion may have a first portion comprising a clamp attachment mechanism and a second portion comprising an interlocking attachment mechanism. Also, multiple mechanisms can be combined on a same portion of the first attachment portion.

[0066] For example, the first attachment mechanism may by a force-fit mechanism and may comprise at least a protrusion wherein the thickness of the protrusion corresponds to the spatial distance formed by a recess between the flap of the handling unit and the body of the handling unit. In other words, the protrusion completely fills the recess at least in thickness direction, such that a frictional force prevents the adapter from dropping out of the recess.

[0067] Alternatively or additionally, the first attachment mechanism may comprise at least a snap-in cantilever and a snap-in tip, wherein the snap-in cantilever may be configured to provide a spring load to the snap-in tip and wherein the snap-in tip may be configured to protrude in a recess of the handling unit. A snap-in cantilever may refer to a type of snap-fit attachment mechanism, where the first attachment portion comprises a cantilever beam, which is attached on one end at the first attachment portion end and free on the other end. The snap-in cantilever may be flexible. The snap-in tip refers to the end of the cantilever beam that engages with the mating part of the handling unit. The shape and design of the snap-in tip are crucial for ensuring secure engagement and proper retention of the components. In particular, the shape of the snap-in tip may be adjusted to fit through a though hole Applicant: VusionGroup GmbH

[0068] Title: Adapter for attaching a display device to a handling unit

[0069] Our ref.: VSG31408PCT

[0070] Date: October 15, 2024 of the handling unit or into a recess of the handling unit. The snap-in tip may be realized by a protrusion, a hook or tab. Spring-load refers to the force exerted by the cantilever beam when it is flexed. This force is a result of the cantilever's material properties, such as elasticity, and its geometric design, such as length, thickness, etc. The spring load determines how much force is required to engage or disengage the snap-in attachment mechanism and affects the holding force once the snap- in attachment is made. Such snap-in attachment may provide a robust and reliable attachment mechanism that is both user-friendly and durable.

[0071] The thickness of the snap-in cantilever may correspond to the spatial distance formed by a recess between the flap of the handling unit and the body of the handling unit. The thickness is measured in the thickness-direction or z-direction of the adapter. If the thickness of the snap in cantilever corresponds to the thickness of a recess, the snap-in cantilever may provide a form-fit attachment additionally to its snap-in functionality. This may couple the first attachment portion using two attachment mechanisms, thus locking the movement of the first attachment portion using the snap-in attachment, and preventing a rotation of the first attachment portion using the form-fit attachment.

[0072] The thickness of the snap-in tip may be smaller than the thickness of the snap-in cantilever. This may enable that the size of the snap-in tip is adjusted to the size of the recess of the handling unit in which the snap-in tip snaps in, whereas the size of the cantilever can be maximized to provide mechanical stability using the form-fit attachment.

[0073] The first attachment mechanism may comprise a first snap-in cantilever and a first snap-in tip and a second snap-in cantilever and a second snap-in tip, wherein the first spring-load of the first snap-in cantilever and the spring-load of the second snap-in cantilever point in different directions, in particular in opposite directions. A snap-in attachment with two cantilevers may provide enhanced stability and stronger retention by evenly distributing forces across two points, reducing stress on each cantilever. This design may increase durability and resistance to separation, making it more reliable under dynamic conditions. Additionally, it may allow for easier and more controlled assembly as it is self-centering.

[0074] The adapter may comprise at least one through hole, which is configured to receive releasing means for the first attachment mechanism. For example, the through hole can be arranged such that the though hole is accessible when the adapter is coupled to the handling unit.

[0075] The through hole may be configured and oriented to guide a releasing means such that the releasing means pushes the snap-in tips away from the recess of the handling unit. The snap-in attachment may thus be released and subsequently reused. Applicant: VusionGroup GmbH

[0078] Date: October 15, 2024

[0079] The first attachment mechanism may comprise one or more structural elements. The one or more structural elements may be configured to restrict the movement of the adapter in z-direction and / or y- direction and / or x-direction. The one or more structural elements may have different shapes. For example, a structural element may have the form of a bar of different geometrical forms or a pin. The shape of the one or more structural elements may further be adapted to structural elements present on the handling unit, including holes and recesses. The structural elements of the adapter may be counter parts of the structural elements of the handling unit. The one or more structural elements of the adapter may be rigid and may allow to be securely anchored in place to provide support and prevent movement of the first attachment portion. The one or more structural elements can be formed in one piece with the adapter. The one or more structural elements may enhance the stability by maintaining the position of the coupled adapter and handling unit, minimizing flexing or shifting, and distributing loads more evenly across the structure of the adapter and / or the handling unit. This makes the assembly more resistant to external forces, vibrations, and potential misalignments.

[0080] Alternatively or additionally, the one or more structural elements may be configured to protrude into one or more recesses of the handling unit. In particular, the one or more structural elements may protrude into a recess formed by the flap, the rim and the body of the handling unit. For example, the one or more structural elements can be arranged and oriented parallel to a snap-in cantilever. The snap-in attachment mechanism attaches the adapter to the handling unit, wherein the one or more structural elements, for example, a rigid bar, primarily stabilizes the attachment by preventing flexing and shifting of the adapter.

[0081] The one or more structural elements may alternatively or additionally be configured to provide a form-fit attachment mechanism and / or a force-fit attachment mechanism. In particular, the first attachment portion may comprise multiple attachment mechanisms. For example, the first attachment portion may comprise a first attachment mechanism realized as a snap-in attachment mechanism or an interlocking attachment mechanism and a second attachment mechanism realized by the one or more structural elements, for example, one or more rigid bars. As such, the advantages of different attachment mechanisms can be combined.

[0082] The thickness of the one or more structural elements may correspond to the spatial distance between the flap of the handling unit and the body of the handling unit. In other words, the dimensions of the one or more structural elements are adjusted to form a form-fit attachment to one or more recesses formed by the flap, the rim and the body of the handling unit.

[0086] The one or more structural elements may be oriented along the thickness direction and / or the width direction of the adapter. Orientation may refer to a preferred axis of a structural element. The preferred axis of a structural element can be given by the main axis of the ellipsoid of inertia of the isolated structural element. The preferred axis can be the axis along the maximum extension of a structural element. For example, a handling unit may comprise a U-shaped recess in which the first attachment portion shall protrude. A "U-shape" refers to a form that resembles the letter "U”. It typically features two parallel vertical sides, connected at the bottom by a horizontal curve or straight line, creating a shape that is open at the opposite side. If the structural element is oriented along the thickness direction of the adapter, the structural element points from one vertical side to the other vertical side of the U-shape. In other words, the structural element may be essentially parallel to the horizontal curve of the U-shape. In this case the structural element may prevent any rotation or shifting around or along the thickness direction of the adapter, as the vertical sides of the U-shape of the recess of the handling unit prevent a movement of the structural element into the direction of the vertical bars. Analogously, if a structural element is oriented along the width direction of the adapter, the structural element may prevent any rotation or shifting around or along the width direction of the adapter.

[0087] Analogous to the first attachment mechanism, the second attachment mechanism may be a releasable attachment mechanism, in particular a reusable attachment mechanism.

[0088] Analogous to the first attachment mechanism, the second attachment mechanism may be a non- releasable attachment mechanism, in particular the second attachment mechanism may not be releasable without destruction.

[0089] Analogous to the first attachment mechanism, the second attachment mechanism may be a mechanical attachment mechanism. A mechanical attachment mechanism refers to mechanism to join or couple the second attachment portion and the display device through physical means, such as interlocking parts, fasteners, friction, screws, clamps, hooks etc. It relies on the shape, material properties, and forces like compression or tension to create a secure connection between the second attachment portion and the display device.

[0090] Analogous to the first attachment mechanism, the second attachment mechanism may be a form-fit attachment mechanism and / or a force fit attachment mechanism.

[0091] Analogous to the first attachment mechanism, the second attachment mechanism may be a snap-in attachment mechanism and / or a clamp attachment mechanism and or interlocking connection. Applicant: VusionGroup GmbH

[0095] Analogous to the first attachment mechanism, the second attachment mechanism may be a magnetic attachment mechanism.

[0096] A magnetic attachment mechanism may use magnets or magnetic materials to securely connect the display device to the second attachment portion without mechanical fastening and / or attachment means. The display device can comprise at least one magnet or magnetic material and the at least the second attachment portion can comprise a magnet or a magnetic material. The magnetic force between the magnets or magnetic materials between the second attachment portion and the display device creates a strong but reversible bond. The magnetic attachment may allow for a quick assembly and disassembly. A magnetic attachment may be useful in applications where a non-invasive, tool-free connection is desired, and it may provide a silent operation and smooth engagement.

[0097] The second attachment mechanism may be configured to receive a display device from the front and / or the back of the adapter. The front of the adapter relates to the side of the adapter that points away from the handling unit when the adapter is coupled to the handling unit. The back of the adapter relates to the side of the adapter that points towards the handling unit when the adapter is coupled to the handling unit. The thickness-axis relates to the direction form the front side to the back side of the adapter. The coupling from the front may enable that the display device can easily be assembled and maintained. The coupling from the back may enable that the display device is not only secured by the second attachment mechanism, but also restricted in movement by the body of the handling unit in the coupled state.

[0098] The second attachment portion may have a transition region with a decreasing thickness in the direction of a handle of the handling unit. The adapter may be arranged adjacent to the handle of the handling unit. To provide an unaffected handling of the handling unit, the adapter and in particular the second attachment portion may be thinned out towards the handle of the handling unit. In this way the handling remains unaffected as the second attachment portion is thin at the side of the handle. Furthermore, the second attachment portion remains mechanically stable as the thickness is unaffected at the side facing away from the handle.

[0099] The second attachment portion may have a display mounting portion, which is configured to receive one or more protruding parts of the display device. A display mounting portion relates to a portion of the second attachment portion that can receive a display device. The display mounting portion may be a geometrically limited area of the second attachment portion, such that the second attachment portion has space to include further features. The display device may have a protruding part. The second attachment mechanism can be formed such that a mechanical coupling with the protruding part can be enabled. As such, the second attachment portion may receive arbitrary display devices Applicant: VusionGroup GmbH

[0102] Date: October 15, 2024 and is not limited to specific second attachment means. In other words, the second attachment portion may have a high compatibility with different display devices.

[0103] The display mounting portion may form the female part and the protruding part of the display device may form the male part of the second attachment mechanism. A "male and female" coupling mechanism refers to a type of connection system where two components are designed to fit together in a complementary way. The "male" part typically features a protruding or insertable element, such as a plug, pin, or shaft, while the "female" part has a corresponding recess or socket designed to receive the male part. Such connection may provide a stable and accurate attachment and ensures alignment, stability, and a proper fit between the two parts.

[0104] The display mounting portion may be configured to receive a battery compartment of the display device. The battery compartment of display devices is typically arranged on the back side of the display device. Thus, the battery compartment can provide points of attack for the second attachment mechanism, without interfering with the functionality of the display device.

[0105] The display mounting portion may comprise one or more recesses or holes configured to receive one or more parts of the display device. Depending on the size, for example the thickness of the one or more protruding parts of the display device, the display mounting portion may be realized as one or more recesses or holes. For example, display devices with a large protrusion can be attached to display mounting portions formed by a hole. For example, display devices with a small protrusion can be attached to display mounting portions formed by a recess. As such, the display mounting portion may be compatible with display devices having a large thickness. For display devices with a small protrusion, a protection, and in particular an encapsulation of the display device may be provided, thus, securing the display device against mechanical impact.

[0106] The display mounting portion may further comprise a mounting frame. A mounting frame relates to at least three contact points in the display mounting portion which contact the display device in the coupled state. The mounting frame can be arranged in the recess or in the hole of the display mounting portion. A mounting frame may also relate to an even contact surface for the display device, which may run around the recess or the hole. The mounting frame may provide a mechanical stop to the display device. Thus the mounting frame may allow an adjustment of the mounting depth of the display device.

[0107] The display mounting portion may comprise one or more drain holes configured to prevent formation of humidity within the adapter and / or accumulation of splash water within the adapter. For Applicant: VusionGroup GmbH

[0108] Title: Adapter for attaching a display device to a handling unit

[0109] Our ref.: VSG31408PCT

[0110] Date: October 15, 2024 example, the drain holes can be arranged and distributed around the mounting frame. If the mounting frame is comprised of contact points instead of an even contact surface, the drain holes can relate to the space between the contact points. Preventing the formation of humidity may provide a hygienic environment and may reduce the exposure of the display device to water.

[0111] The display mounting portion may comprise at least one hook or clamp, which is configured to attach the display device to the display mounting portion. A hook may be realized as a U- or V- shaped protrusion. The U- or V-shape may provide a spring-force, which enables coupling the display device to the display mounting portion. A hook can furthermore be understood as a rounded snap-in beam.

[0112] The display mounting portion may comprise at least three hooks or clamps, which are arranged around the circumference of the display mounting portion. Thus, the display device may be protected against falling out.

[0113] The at least one hook may comprise a main body and a snap-in body, wherein main body may be configured to provide a spring-load to the snap-in body and wherein the snap-in body may be configured to engage with the display device. The hook refers to a bended snap-in cantilever and the snap-in body refers to the snap-in tip, such that the above explanations apply analogously.

[0114] The second attachment portion may comprise a protection bump, which is configured to protect the display device from mechanical impact. The protection bump may protrude over the display device in the thickness direction of the adapter (or z-direction) in the coupled state. In particular, there might be a geometrical plane which contacts the outer surface of the protection bump and a geometrical plane which contacts the surface display device, wherein the geometrical plane of the protection bump is separated from the geometrical plane of the display and does not intersect the geometrical plane of the display device. The protection bump may be elevated relative to the surface of the display device, when the display device is attached to the adapter. Such protection bump may be implemented by one or more protruded areas on the front side of the display device.

[0115] The protection bump may be arranged at least in part around the display mounting portion. The protection bump may comprise a single bump or several locally separated bumps. For example, there can be two, three or more bumps which are arranged around the display device, when the display device is coupled to the second attachment portion. For example, the protection bump may also be a single bump or protection wall, which continuously runs around the display attachment portion. Applicant: VusionGroup GmbH

[0118] Date: October 15, 2024

[0119] The second attachment portion may be configured to continue the outer shape of the handling unit to form an even transition from the flap and / or the rim of the handling unit to the second attachment portion. In particular, the first attachment portion can be fully covered by the flap and the rim. Thus, the second attachment portion may be the only visible portion of the adapter. An even transition or a smoot transition may be achieved when the flap and / or the rim of the handling unit are shaped such that the transition does not have any edges, dents or height differences. An even transition is also achieved if the surface of the handling unit appears to be extending towards the second attachment portion, when the adapter is coupled to the handling unit. This may provide a visually appealing appearance. Furthermore, the lack of dents, and edges allows to reduce dirt and dust between the handling unit and the adapter. Furthermore, the functionality of the handling unit, e.g., handling, stackability, etc., may be maintained, as the adapter is not protruding over the maximum spatial dimensions of the handling unit.

[0120] At least the second attachment portion may be configured to form a form-fit connection with the outer contact points of the handling unit. The handling unit may have a particular shape to which the adapter shall be coupled. The surface of the second attachment portion can be such that the surface of the handling unit in the particular area appears to be extending towards the display device. When the second attachment portion and the outer contact points of the handling unit are form-fit, the second attachment portion may have the negative shape of the handling unit in that particular location, such that the second attachment portion matches to the shape of the handling unit. This may not only provide a visually appealing appearance, but a strong connection of the adapter, as the adapter is stabilized or fixed by the contact points.

[0121] The first attachment portion and the second attachment portion may be separated by a transition region limited by a transition border. The transition region relates to a protruded region on the front side of the adapter which separates the first attachment portion and the second attachment portion. The transition border may also provide a smooth transition from the flap and / or rim of the handling unit to the second attachment portion.

[0122] The thickness of the transition region may correspond to the thickness of the flap and / or the rim of the handling unit. For example, the first attachment portion is covered by the flap and provides a from-fit attachment to a recess of the handling unit. In this case, the flap covers the surface of the first attachment portion. If the thickness of the transition border corresponds to the thickness of the flap and / or the rim of the handling unit, a smooth transition from the surface of the flap and / or rim of the handling unit to the second attachment portion can be achieved.

[0125] Date: October 15, 2024

[0126] This may provide for a visually appealing appearance. Furthermore, the adapter may be stabilized by the transition border, while edges or dents are omitted.

[0127] The transition border may be rounded off. The transition border of the transition region, which elevates the thickness of the first attachment portion to the thickness of the second attachment portion, may be rounded off to prevent the formation of sharp edges. As sharp edges quickly become dirty and wear off, the rounded off border may allow increasing the service life and maintain the visual appearance of the adapter.

[0128] The first attachment portion may be covered by the flap of the handling unit when the adapter is attached to the handling unit and wherein the second attachment portion is not covered by the flap of the handling unit. This allows to hide and secure the first attachment portion, whereas the second attachment portion can be easily accessed.

[0129] The adapter may be configured to maintain the maximum spatial dimensions of the handling unit, when the adapter is coupled to the handling unit. The maximum spatial dimensions are typically given by the producer or manufacturer of the handling unit. Maximum spatial dimensions refer to the largest outer measurements (length, width, and height) of a handling unit, defining the total space it occupies. These dimensions are crucial for determining the compatibility of the handling unit with storage systems, transport vehicles, and handling equipment. All participants in a chain of goods or production chain may have to consider the maximum spatial dimensions of the handling unit, such as logistics companies to determine to loading quantity of trucks or merchants to determine the storage space. Maintaining the maximum spatial dimensions of the handling unit has several advantages. First, the participants of the chain of goods are not affected by the adapter and existing procedures and plans can be maintained. Second, the storage space of the handling unit is not affected, as the adapter coupled to the existing structure of the handling unit.

[0130] The adapter may be made of or comprise the same material as the handling unit. Typically, the material of the handling unit goes along with certain criteria and requirements. For example, the material must be strong enough to support the weight of the contents and withstand wear and tear, impact, and handling stress during transport and storage. Common materials include plastic, metal, or reinforced cardboard. For example, the material should be light enough to minimize the overall weight of the handling unit, reducing transportation costs and easing manual handling, while still maintaining adequate strength. For example, for certain applications, especially in food, pharmaceutical, or outdoor industries, the material must resist moisture, chemicals, and environmental factors to protect the contents. For example, sustainability considerations may require the materials to be recyclable or reusable, minimizing environmental impact over the handling unit’s lifecycle. For Applicant: VusionGroup GmbH

[0131] Title: Adapter for attaching a display device to a handling unit

[0132] Our ref.: VSG31408PCT

[0133] Date: October 15, 2024 example, the material must be economically viable, balancing initial cost with the expected lifespan and durability of the handling unit. The adapter may fulfill the same material requirements as the handling unit, such that also the combination of adapter and handling unit can be used for the intended application.

[0134] The adapter may be made of or comprise a food-safe material. This may allow the adapter and the handling unit with the adapter to be used in the food industry.

[0135] The machine handling of the handling unit with the coupled adapter may correspond to the machine handling of the handling unit without the coupled adapter. Thus, the adapter is configured to maintain machine handling capabilities of the handling unit. Handling of a handling unit refers to the manual or automated processes involved in moving, lifting, or positioning a handling unit (e.g., a pallet, container, or package) within a facility or during transport. This includes activities like loading, unloading, carrying, stacking, and arranging, typically performed by personnel or machines. Machine handling of a handling unit involves the use of mechanical equipment, such as forklifts, conveyors, automated guided vehicles (AGVs), or robotic arms, to move, lift, or manipulate the handling unit. This method improves efficiency, reduces labor costs, and enhances safety by minimizing human involvement in the physical handling process. As the machine handling is unaffected by the adapter, existing machine handling routines can be further used.

[0136] The stackability of the handling unit with the coupled adapter may correspond to the stackability of the handling unit without the coupled adapter. Thus, the adapter is configured to maintain stackability of the handling unit. Stackability may refer to the ability of a handling unit to be placed on top of another similar unit in a stable manner, without damaging the contents. Stackability may also refers to the ability of a handling unit to be placed in one another. In particular, maintaining the stackability may also include that the adapter and the display device are not damaged when the handling units are stacked. As the stackability is maintained, the above advantages of stackable handling units are maintained.

[0137] The foldability of the handling unit with the coupled adapter may correspond to the foldability of the handling unit without the coupled adapter. Thus, the adapter is configured to maintain foldability of the handling unit. Foldability relates to the ability of a handling unit to collapse or reduce its size when not in use. This feature saves space during return transport or storage, making the handling unit more versatile and cost-effective when empty. As the foldability is maintained, the above advantages of foldable handling units are maintained. Applicant: VusionGroup GmbH

[0141] The functionality of the handling unit with the coupled adapter corresponds to the functionality of the handling unit without the coupled adapter. Thus, the adapter is configured to maintain the functionality of the handling unit. For example, the handling units can be grabbed, carried, stacked, folded, transported, loaded, filled, and the like, as a handling unit without the adapter.

[0142] The adapter is configured to maintain accessibility to and functionality of the handles of the handling unit with the coupled adapter. The handle of a handling unit refers to a designated feature or grip area, such as a loop, recess, hole or protrusion, designed to facilitate lifting, carrying, or maneuvering of the handling unit. It is typically ergonomically designed to provide a secure and comfortable grip, enabling easier handling by workers. As the handles are maintained, the handling of the handling units remains unaffected.

[0143] The second attachment portion may be configured to couple the display device comprising coupling means configured to be coupled with the second attachment portion of the adapter using the second attachment mechanism.

[0144] The second attachment portion may be configured to couple the display device, wherein the display device may be an electronic shelf label. An electronic shelf label (ESL) is a digital price tag or information display, often used in retail environments, that automatically updates product prices, stock information, or promotions. The adapter may allow mounting existing ESLs to the handling units, which may further reduce manufacturing costs.

[0145] The second attachment portion may be configured to couple the display device, wherein the display device comprises an e-ink display. An e-ink display, or electronic ink display, is a low-power display technology that mimics the appearance of ink on paper. It uses electrophoretic ink to form high-con- trast, easy-to-read text and images, even in bright light, and is commonly found in e-readers and electronic shelf labels due to its low power consumption and readability. Using e-ink displays may allow to use the same display device for multiple years.

[0146] The second attachment portion may be configured to couple the display device, wherein the display device comprises a housing, configured to be receivable by the adapter. The housing of a display device refers to the outer casing or enclosure that may protect the internal components of the display, such as the screen, electronics, and power supply. It is typically designed for durability, aesthetic appeal, and functionality, often including features for mounting or connecting the device to external systems. As the housing may be receivable by the adapter, in particular by the display attachment portion, the housing has features or points of attack, with which the second attachment mechanism may interact, such that the display device can be coupled to the second attachment portion.

[0150] In particular, the second attachment mechanism can be configured to receive existing display devices, such that the shape or design of the display devices may be maintained.

[0151] The second attachment portion may be configured to couple the display device, wherein the housing may have a front cover and a back cover. The front cover comprises and / or encloses the actual display of the display device. The front cover of the display points away from the handling unit in the coupled state, such that the display can be read by a user, worker or machine. The back cover comprises and / or encloses the electronics of the display device. The back cover of the display device points towards the handling unit in the coupled state, such that the second attachment mechanism can be visually hidden behind the front of the display device. The division into two covers may enable the housing to be accessible for maintenance or repair.

[0152] The second attachment portion may be configured to couple the display device, wherein the front cover may comprise a frame and an optional protection film, which is configured to provide a protective layer for the display. The frame may run around the display such as to provide a protection against mechanical impact or to cover up display electronics which extend laterally from the display. The protection film may be a transparent film and / or semi-transparent film and / or a polarizing film that. The protection film may protect the display against direct mechanical impact. Furthermore, the protection film may improve the quality of the displayed information. For example, the protection film may improve the contrast of the displayed information.

[0153] The second attachment portion may be configured to couple the display device, wherein the housing comprises a controllable locking mechanism having an open and a closed state, wherein, in the closed state, a lock spring presses a lock pin into a recess of the adapter. The controllable locking mechanism relates to a mechanism, which can intentionally be switched between and open state and a closed state. In the open state, the display device can be released from the second attachment portion, whereas in the closed state, the display cannot be released from the second attachment portion. The controllable locking mechanism may form or may be part of the second attachment mechanism interacting with the display mounting portion. In an open state, a lock pin can be reversibly stored in a lock cartridge, where a lock spring exerts a spring force on the lock pin. When the state is changed to the closed state, the lock pin can be released from the lock cartridge, such that the lock pin extends or protrudes into a recess of the adapter. Furthermore, the lock pin can be in a closed state before the display device is attached to the display mounting portion. By pushing the display into the display mounting portion, the lock pin can be pushed inside the lock cartridge, for example by an edge of the display mounting portion. Thus, the locking mechanism is in the open state, where the spring is compressed, and the load on the lock pin is greatest. When the display Applicant: VusionGroup GmbH

[0156] Date: October 15, 2024 device is pushed further over the edge of the display mounting portion into the final position in the display mounting portion, the lock pin may automatically protrude into a recess of the adapter due to the spring load. The display device then rests in the display mounting portion in its locked state. The locking mechanism can prevent theft of the display device of unauthorized exchange of the display device. To enable reusability of the display device and the adapter, the display device may be released from the display mounting portion by a specific tool. This tool may push or pull the pin back into the lock cartridge. The tool may move the pin by mechanical or magnetic force. For example, by approaching a magnetic tool to the display device, the pin is moved back into the lock cartridge and the display device can be removed from the display mounting portion of the adapter.

[0157] The second attachment portion may be part of the housing of the display device and may thereby couple the display device. In particular, the second attachment portion may be formed in one piece with the housing of the display device. As the housing and the second attachment portion may be formed in one piece, they may be formed as a single, unified structure in the production process without assembling or joining. In other words, the display device may have a housing that has the shape of the adapter and / or the adapter may form the housing of the display device. This may have the advantage that the display device itself has all of the above functionalities and advantages of the adapter. Furthermore, this may have the advantage that the display device is inextricably coupled to the adapter, which may reduce the number of parts in the production process, and thereby allow for a more cost efficient and easier production.

[0158] The second attachment portion may be configured to couple the display device, wherein the display device may comprise at least one circuit board. The circuit board may comprise one or more processors (CPU) executing instructions and processing data and user inputs, memory, e.g., RAM (Random Access Memory), temporarily storing data that the one or more processors use while performing tasks, data storage that stores an operating system, software and user data, in particular user input data. The display device may further comprise power supply that provides the necessary electrical energy to the components. The circuit board may allow the abovementioned components to communicate with each other.

[0159] The second attachment portion may be configured to receive the display device, wherein the display is waterproof. This may enable the adapter to be used with the display in a humid or wet environment.

[0160] The back cover may comprise at least one mounting groove, which is configured to receive a snap- in body or clamp of the second attachment mechanism of the adapter.

[0163] Date: October 15, 2024 guide the snap-in body or clamp for attachment. It allows for easy installation and alignment of elements, such as brackets or fasteners, ensuring stable and precise positioning of the mounted display device. The mounting groove can run around the circumference of the back cover and / or extend over a portion of the back cover, for example over half of the length of the back cover or over the entire length of the back cover. It is also possible that the mounting groove only contains mounting dents, which are designed such that the snap-in body or clamps can interact with the mounting dents. The mounting groove may also be formed partially around the back cover and / or in sections of the back cover in order to provide mounting dents for a snap-in or clamp attachment. The usage of a mounting groove allows that the flexible and mechanically loaded part, i.e. the clamp, snap-in hook or cantilever, is arranged on the adapter and not on the more expensive display device, which may render the display device more robust and cheaper to produce.

[0164] The second attachment portion may be configured to couple the display device, wherein the cross section of the display device with the front cover and the back cover is essentially H-shaped. Essentially H-shaped refers to a cross section, that may have a central section (the middle bar of the "H"), and two arms (the left and the right bars of the “H”), which extend vertically from either side of the central section. The arms may be symmetrical or asymmetrical. In particular, the arms form two recesses with the main body. The recesses can be used by the second attachment mechanism for interlocking attachment or snap-in attachment mechanisms. In general, the second attachment mechanism can protrude into the recesses of the H-shaped cross section to provide a mechanical fixation of the display device in the display mounting portion. For example, the cross section is essentially H-shaped if the display device has a rectangular cross section, but two opposing sides have dents or grooves. For example, the cross section is essentially H-shaped if the display device has an elliptical cross section, but the ellipse has grooves on opposite sides, where the major axis of the ellipse intersects the surface of the ellipse. As such, the display device may provide an easily accessible counterpart for the second attachment mechanism, which is integrally formed with the display device.

[0165] The second attachment portion may be configured to couple the display device, wherein the display device may comprise an antenna interface, configured to send and receive electromagnetic signals. An antenna interface refers to a point of connection between the device's communication module and its antenna. This interface typically includes circuitry and connectors that transmit signals between the communication module and the antenna, enabling the device to send and receive radio frequency (RF) signals which transport information. As the display device may send and receive information, it is possible to read, update and control the display device remotely. Applicant: VusionGroup GmbH

[0169] The second attachment portion may be configured to couple the display device, wherein the display device may comprise at least one communication module. A communication module refers a component responsible for handling the device’s wireless or wired communication functions. It can include hardware and software for supporting various communication protocols such as Wi-Fi, Bluetooth, cellular networks, or other wireless communication standards.

[0170] The second attachment portion may be configured to couple the display device, wherein a first communication module may be configured to communicate with a portable handheld device, in particular a smartphone and / or a remote control. For example, handheld devices may be used to read information from the display device and feed the information into a network system. In this way, incoming goods can easily be registered. For example, handheld devices may further be used to send information to the display device from a network system. In this way, commissioning of goods could be simplified, as the process could be automated.

[0171] The second attachment portion may be configured to couple the display device, wherein the signal range of the first communication module may be less than 30 cm, preferably less than 20 cm, more preferably less than 10 cm. An advantage of short-range communication protocols may be the power efficiency, making them ideal for battery-powered devices like wearables, sensors, or display devices. They can operate efficiently without frequent recharging. Furthermore, due to the limited range, short-range communication is inherently more secure. The shorter distance reduces the risk of unauthorized interception or eavesdropping. For example, short-range communication can be used for a registration of individual handling units.

[0172] The second attachment portion may be configured to couple the display device, wherein the first communication module may comprise a RFID and / or NFC interface and / or BLW interface and / or UWB interface and / or BLE interface and / or Wi-Fi interface.

It can indicate various information, e.g., regarding power, connectivity, error states, or battery level, typically using different colors or blinking patterns. In particular, the LED can be used in a “blink-to-find” method. For example, a worker in a warehouse could trigger the LED of the display device attached to a handling unit the worker wants to interact with to blink or light up. It is also possible to trigger the LEDs of multiple display devices at the same time. For example, in a warehouse that stores perishable goods, a communication command could be sent to all handling units in the warehouse commanding the LEDs of the handling units to blink or light up, if the date of receipt of goods of the handling unit in the warehouse lies before a specific date. The LEDs can be triggered using a communication module of the display device.

[0231] Detailed description of preferred embodiments

[0232] In the following, the invention will be explained in more detail with reference to the accompanying figures. In the figures, like elements are denoted by identical reference numerals and repeated description thereof may be omitted in order to avoid redundancies.

[0233] Fig. 1 A shows a typical handling unit 3. A handling unit 3 can be used in the transportation business to transport goods, such as food, mechanical parts, cloths etc. The handling unit 3 typically has a length between 150mm and 1200mm, a width between 100mm and 800mm, and a height between 100mm and 1000mm. A problem of such handling units 3 is that they do not comprise a digital interface. Thus, it is often not possible to automate processes in field of logistics and / or storage. A particular problem is that already millions of such handling units 3 exists alone in the European market. Applicant: VusionGroup GmbH

[0235] Our ref.: VSG31408PCT

[0236] Date: October 15, 2024

[0237] It is therefore not economical to replace the handling units 3 by digital handling units. In contrast, a solution which provides existing handling units 3 with a digital interface is preferred.

[0238] Fig. 1 A shows a typical handling unit 3 which comprises five walls 300, four side walls and one bottom wall. The five walls 300 form the body 30 of the handling unit 3. The walls 300 are connected such that they enclose a volume of the body 30, which can be used to provide a cargo space. On the opposite side of the bottom, the upper side of the body 30 is formed by the edges of the side walls 300.

[0239] The upper side of the body 30 is connected to the rim 32 of the handling unit 1 . The rim 32 of the handling unit may comprise various holes 39 and recesses 36 which provide specific functionalities to the handling unit 3 such as a ventilation, drainage or a stackability of the handling unit 3. The rim 32 may stabilize the body 30 of the handling unit 3. The rim 32 protrudes outwards and may be arranged substantially perpendicular to the side walls 300. The rim 32 may furthermore not protrude inwards, i.e. towards the opening of the handling unit 3, such that the access to the cargo volume is not restricted or minimized by the rim 32.

[0240] The rim 32 may also be connected to a flap 34. The flap 34 extends from outer edge of the rim 32, that is, the edge of the rim 32 that is not connected to the body 30 of the handling unit 3, in the direction of the bottom of the body 30. In other words, the side wall 300, the rim 32 and the flap 34 form a U-shaped recess 36. The opening of the U-shaped recess 36 points towards the direction of the bottom of the body 30.

[0241] In case an element is placed into the U-shaped recess 36, the flap 34 restricts movement of the element to and away from the body 30 of the handling unit 3 and the rim 32 restricts movement of the element above the level of the upper side of the handling unit 3. A cross section of the handling unit 3 along the dashed line of Fig. 1 A is shown in Fig. 1 B.

[0242] The recess 36 formed by the side wall 300, the rim 32 and the flap 34 may also contain struts 38, as shown in Fig. 1 C. The cross section of Fig. 1 C refers to the dotted line in Fig. 1A. The struts 38 can form divide the recess 36 into multiple recesses 36. Thus, the struts 38 may also provide side walls of recesses 36 blocking movements of elements placed into the recesses 36. As can be seen in Fig. 1 C, the rim 32 can have holes 39. The holes 39 of the handling unit 1 can be used as anchor points for an attachment mechanism.

[0243] Fig. 1 D shows a detailed section of Fig. 1A. The handling unit 3 comprises two handles 31 placed on each of the short side walls of the rectangular handling unit. However, handles may additionally Applicant: VusionGroup GmbH

[0246] Date: October 15, 2024 or alternatively also be placed on the long side walls of the handling unit. The handles 31 of the handling unit may have a circumferential protrusion 310, which is elevated from the side wall 300 of the handling unit 3. The circumferential protrusion 310 may have different thicknesses depending on the location of the protrusion. The upper side of the circumferential protrusion 310 may have a greater thickness than the bottom side of the circumferential protrusion 310. The circumferential protrusion 310 can also connect the flap 34 to the side wall 300 and thus stabilize the recess formed by the side wall 300, the rim 32 and the flap 34. The circumferential protrusion 310 therefore has the same function regarding delimiting or defining one or more of the recesses 36, as a strut 38 or forms a strut 38.

[0247] Fig. 1 E shows another detailed section of Fig. 1 A. The side wall 300, the rim 32 and the flap 34 form a recess 36, which is spatially limited at least by the strut 38 or circumferential protrusion 310.

[0248] Fig. 1 F shows another detailed section of the handling unit 3 with a coupled adapter 1 to which a display device or unit 2 is attached. The adapter 1 protrudes into the recess 36 formed by the flap 34, the rim 32 and a side wall 300 of the handling unit 3. In particular, the adapter 1 can be used with an existing handling unit 3 thus enabling the handling unit 3 to be retrofitted with a display device 2. Therefore, structural modifications of the handling unit 3 or the production process of the handling unit 3 can be avoided. No screwing and / or drilling and / or gluing and / or welding and / or riveting is necessary to couple the adapter 1 to the handling unit 3, as the adapter 1 only uses already existing structural elements of the handling unit 3 such as recesses 36, struts 38, including circumferential protrusion 310, and holes 39.

[0249] As further shown in Fig. 1 F, the adapter coupled to the handling unit 3 does not extend the maximum dimensions of the handling unit 3. In particular, the adapter provides a smooth transition to, and as such continues, the surface of the flap 32 of the handling unit. However, the adapter 1 does not restrict or minimize the handle opening 31 . Thus, the functionality of the handling unit is maintained.

[0250] Fig. 1G shows two handling units 3, 3’ each mounted with the adapter 1 . The handling unit 3’ where is stacked into the handling unit 3. The adapter 1 does not extend beyond the flap in the stacking direction, so that stacking does not harm or destroy the adapter 1 and / or the display device 2.

[0282] Date: October 15, 2024

[0283] The illustrated second attachment mechanism 50 is a mechanic attachment mechanism, as it comprises hooks 506, which can protrude into the mounting grooves 2220 of the display device 2 to secure the display device 2 in the display mounting portion 500. However, the display device 2 may also be attached magnetically to the display mounting portion 500.

[0284] The second attachment mechanism 5 may also comprise one or more holes or drain holes 504 which are configured to drain splash water or humidity from the display mounting portion 500 and thus from the display device 2. The holes 504 are preferably arranged on the bottom side of the display mounting portion 500, as this allows reducing the humidity or splash water that accumulates at the bottom side of the display mounting portion 500.

[0285] Figure 5B shows the left side 104 of the adapter 1 and a schematic cross section through the recess 36 formed by the flap 34, the rim 32 and the side wall 300 of the handling unit 3, indicated as a dashed line. The adapter 1 has bars 44, the thickness TB of which corresponds to the thickness of the recess 36. The bars 44 stabilize the adapter 1 in the recess 36 such that a motion or translation in the thickness direction of the fixed bars 44 can be avoided. It is also visible that the thickness TT of the snap-in tip 422 is smaller than the thickness TC of the snap in cantilever 420. This allows the snap in tip 422 to protrude through an existing hole 39 of the handling unit 3, whereas the snap in cantilever may be as thick as the recess 36 to stabilize the adapter 1 in the recess 36.

[0286] Fig. 5C shows the right side 105 of the adapter 1 . Fig. 5D shows the bottom side 101 of the adapter 1 . Fig. 5E shows the top side 100 of the adapter 1 . Fig. 5F shows the back side 103 of the adapter 1 . Fig. 5G to 5J show the different isometric perspectives of the adapter 1 in more detail.

[0287] Fig. 6 shows the coupling of the adapter 1 and the handling unit 3. When the adapter 1 with the snap-in attachment 42 protrudes into a recess 36 of the handling unit 3, the holes 39 of the rim 32 of the handling unit 3 will provide a mechanical attack point for the snap-in tips 422. The snap-in 420 will provide a mechanical force on the snap-in cantilever 420, such that the snap-in cantilever 420 bends, and the snap-in tips 422 can protrude through the holes 39. Once the snap-in tip 422 are protruded through the holes 39, the spring-load of the snap-in cantilever 420 will lock the snap- in tips 422 in the rim 32 of the handling unit 3. In other words, the first spring load of the first snap-in cantilever 420 and the spring load of the second snap in cantilever 420 point in different directions, in particular, in opposite directions.

[0288] After the coupling, as shown in Fig. 1 F, the first attachment portion may be partly or fully covered by the flap 34 of the handling unit 3 and / or the rim 32 of the handling unit 3. Therefore, all mechanical Applicant: VusionGroup GmbH

[0291] Date: October 15, 2024 parts that contribute to the coupling or the stabilization of the coupling of the adapter 1 with the handling unit 3 may be visually hidden.

[0292] Fig. 7 shows the adapter 1 with the attached display device 2. In particular, the display device 2 is offset in the direction of the back side, such that the surface of the front side 102 of the display device 2 lies behind the front plane of the adapter 1. In other words, the second attachment portion 5 has a protection bump 54 which protects the display device 2 from mechanical impact. The protection bump 54 is elevated to the surface of the attached display device 2 and can at least in part be arranged around the display device 2.

[0293] Fig. 8 shows the adapter 1 with a coupled display device 2. In particular, the second attachment portion 5 and the housing 20 of the display device 2 are formed in one piece, such that the adapter forms the housing 20 of the display device 2. The display device 2 with the adapter 1 as a housing 20 may combine all of the above functionalities of a separate display device 2 and a separate adapter 1 .

[0294] Fig. 9 shows an example of use of the handling unit 3 with the coupled adapter 1 and the coupled display device 2. Each display device 2 is configured to provide information about the contents of the handling unit 3. The display devices 2 are coupled via the adapter 1 to the handling unit 3. The display devices 2 for example are configured to display the product type, sensor data, the year of production of the product in the handling unit or a country code that identifies the origin of the product.

[0295] Each display devices 2 may have a communication module which allows communicating with a network, such that all of the abovementioned data can be send to the network. For example, the data of the display devices 2 can be read when the handling units 3 are provided to a storage facility or a supermarket.

[0296] For example, after a cargo delivery, a first selection of the products may be performed, such as to find hazardous contents and non-hazardous contents. The network may send a control signal to the display devices 2 such that all display devices 2 of handling units 3 that contain hazardous goods shall light up. For example, the LEDs of display devices 2 of handling units 3 that contain old fish that was not stored properly can light up. For example, the LEDs of display devices 2 of handling units 3 that contain flammable materials can light up. For example, the LEDs of display devices 2 of handling units 3 that contain poisonous products can light up. These handling units 3 can be handled with care and further processed or stored. All other handling units 3 which do not contain any hazardous goods can then be processed and stored without greater caution. Applicant: VusionGroup GmbH
