[0019] GENERAL BENEFITS

[0020] The advantages of the inventions are given in the following description and embodiments.

[0021] DETAILED DESCRIPTION

[0022] The invention relates to a module interface for electrically connecting a module to a work surface, a safety workbench for generating a laminar airflow, a work surface, a sensor device for detecting a physical quantity acting on at least one sample body, and a multiple holder for positioning a work tool on a work surface.

[0023] The module interface for electrically connecting a module to a work surface comprises at least one module-side contact element, which is preferably arranged on a bottom side of a module, and at least one contact surface, which is preferably arranged within the work surface, wherein the module-side contact element is configured to be placed on the contact surface, wherein the contact surface has a first contact point, wherein the module-side contact element has a second contact point, wherein the first contact point and the second contact point are configured to establish an electrical connection between the contact surface and the module-side contact element, wherein the contact surface has a first fixing element, and wherein the module-side contact element has a second fixing element.

[0024] Electrical connection describes a process in which two electrical contact points are connected in such a way that an electrical signal (e.g., a current flow) or an electromagnetic signal (e.g., a radio connection) can be transmitted between them.

[0025] white ip | Patent & Legal PCT application. The term "electrical connection" refers to any connection through which an electrical signal (e.g., a current flow) or an electromagnetic signal (e.g., a radio link) can be exchanged between a first contact point and a second contact point. A galvanic connection is a specific type of electrical connection in which a galvanic connection is established by contacting a first and a second contact point. A contact point could be, for example, a bus connection, particularly a plug connection. However, it is also possible that no galvanic connection is implemented.Instead, the first and second contact points can be interconnected in such a way that an electrical connection based on electromagnetic waves is realized, whereby a first and / or second contact point can be designed as a coil, so that energy and / or information can be exchanged via electromagnetic interactions between the module-side contact element and the contact surface.

[0026] A module is a device used to hold sample carriers (e.g., microtiter plates, cell culture plates). A module may include an internal energy storage device and a sensor device.

[0027] The term "work surface" refers to an area located, for example, within a sterile workbench or safety cabinet. Equipment or objects necessary for cell culture experiments may be arranged on the work surface.

[0028] Preferably, the work surface is made of a material (e.g., glass, plastic, metal) that is easy to clean and chemically stable, meaning it is not attacked by acids or alkalis. The area above the work surface, where the experiments are carried out, is called the sterile work area.

[0029] While the primary function of the module and a multi-holder is the receiving and storage of sample carriers, biological material, tools or the like, a module-side contact element refers to a device which is arranged on the module or the multi-holder and extends the module or the multi-holder, in addition to receiving and storage, to include further functions or features described herein.

[0030] white ip | Patent & Legal PCT Application. A bottom side refers to the side or surface of the module that is closest to the work surface or contact surface during intended use. The top side is opposite the bottom side.

[0031] A contact surface is an area located within the work surface, but which has additional features described herein. Preferably, the contact surface is flush with the work surface or essentially forms a continuum with it.

[0032] According to a further embodiment, the first contact point is recessed into the surface such that its surface facing the contact area is at the same level as the surface of the contact area or the surface of the working surface. This advantageously prevents or minimizes the accumulation of contaminants on the contact area. As a result, both the contact area and the working surface are easy to clean.

[0033] The contact surface represents the area on which the module-side contact element can be placed. This placement preferably establishes the electrical connection between the contact surface and the module-side contact element.

[0034] According to one embodiment, the contact surface has a plurality of first contact points, with individual contact points being provided for power supply and other contact points for data transmission, so that a functional separation of power transmission and data transmission is achieved.

[0035] According to a preferred embodiment, a computing unit is provided. Preferably, the internal computing unit is configured to determine a contact status, in particular based on an electrical parameter, in order to verify a reliable electrical connection.

[0036] The module interface for electrically connecting a module to a work surface is preferably used in a safety workbench as defined herein, which also includes laboratory equipment enclosures, automated systems, or sample processing facilities. Therefore, the module interface can also be referred to as a laboratory equipment module interface, a sample processing facility module interface, a laboratory workstation module interface, or a laboratory workstation-integrated module interface.

[0037] white ip | Patent & Legal PCT Application: The work surface has at least one contact surface and preferably a plurality of contact surfaces arranged side by side. The plurality of contact surfaces can be arranged in a substantially grid-like pattern on the work surface.

[0038] Preferably, each of the contact surfaces is arranged within a field of the grid.

[0039] Preferably, each field of the grid is assigned a unique position information so that the internal computing unit can determine the position of a contact surface within the grid.

[0040] According to one embodiment, the internal computing unit is configured to perform a plausibility check, based on the position within the grid, to determine whether an identified module is provided at the relevant contact surface.

[0041] A first contact point forms an electrical connection with a second contact point if they are sufficiently close to each other. For example, a galvanic connection can be established by contacting a first and a second contact point.

[0042] A contact point can, for example, be a BUS connection. However, it is also possible that no galvanic connection is implemented. Instead, the first and second contact points can be interconnected in such a way that an electrical connection based on electromagnetic waves is established. A first and / or second contact point can be designed as a coil, allowing energy and / or information to be exchanged via electromagnetic interactions between the module-side contact element and the contact surface. This advantageously eliminates the need for a galvanic connection, such as a plug connection like a BUS connection, making the module interface easier to clean.

[0043] The first contact point, if implemented as a plug connection (e.g., a bus connection), is preferably designed to be symmetrical or rotatable with respect to the work surface. In a symmetrical design, the module-side contact element can advantageously be connected to the first contact point in at least two orientations in the horizontal direction relative to the work surface, where the horizontal direction is parallel to the surface of the work surface. Rotatability of the first contact point in the horizontal direction relative to the work surface advantageously allows for an even more flexible arrangement of the module-side contact element, enabling it to be positioned at any angle relative to the horizontal direction relative to the work surface.

[0044] white ip | Patent & Legal PCT application The second contact point is operatively connected to the first contact point in such a way that the electrical connection is enabled.

[0045] A first fixing element is understood to be a means which, in conjunction with a second fixing element, is designed to fix the module-side contact element to the contact surface and thus to the working surface. The first fixing element is arranged on the contact surface, while the second fixing element is arranged on the underside of the module-side element or the underside of the multi-holder.

[0046] The modular interface according to the invention is particularly intended for use within a laboratory workspace to electrically connect modules, multi-holders, or other elements to a work surface. A key focus is that the modular interface, especially on the work surface side, is easy to clean or disinfect, while simultaneously enabling simple connection of modules, multi-holders, or other elements to the work surface, thus eliminating the need for user-connected and disconnected cable connections.

[0047] Preferably, functional elements arranged on the work surface are encapsulated, so that surface cleaning is possible without disassembly.

[0048] According to another embodiment, the first contact point with the contact surface is essentially flat, with the surface of the first contact point being flush with the contact surface or only slightly recessed into the contact surface. This advantageously prevents or minimizes the accumulation of contaminants on the contact surface. As a result, the contact surface, as well as the working surface, is easy to clean or disinfect.

[0049] According to one embodiment, the first fixing element is arranged in operative connection with the second fixing element to magnetically fix the module-side contact element to the contact surface when the module-side contact element is placed on the contact surface.

[0050] A magnetic connection is essentially a force-fit connection, where the load-bearing capacity of this connection is determined by the attractive force of the first and second fixing elements. The module-side contact element is connected via the

[0051] white ip | Patent & Legal PCT application magnetic fixation fixed to the contact surface in such a way that the module-side contact element does not slip on the contact surface during intended use.

[0052] The magnetic fixation is preferably strong enough to attract the module and fix it sufficiently to the work surface, but weak enough that a user or an actuator, such as a robot arm, can lift the module.

[0053] The force with which the magnetic fixing elements attract each other is preferably in the range of 0.5N to 10N, more preferably in the range of 1N to 8N and most preferably in the range of 1.5N to 6N.

[0054] According to a preferred embodiment, the module interface for electrically connecting a module to a work surface comprises at least one module-side contact element, which is preferably arranged on a bottom side of a module, and at least one contact surface, which is preferably arranged within the work surface, wherein the module-side contact element is configured to be placed on the contact surface, wherein the contact surface has a first contact point, wherein the module-side contact element has a second contact point, wherein the first contact point and the second contact point are configured to establish an electrical connection between the contact surface and the module-side contact element, wherein the contact surface has a first fixing element, and wherein the module-side contact element has a second fixing element, wherein the first fixing element is configured to operatively connect with the second fixing element.to magnetically fix the module-side contact element to the contact surface when the module-side contact element is placed on the contact surface.

[0055] According to one embodiment, the magnetic attraction force is adjustable, allowing switching between a fixing mode and a release mode.

[0056] According to a preferred embodiment, the module interface for electrically connecting a module to a work surface comprises at least one module-side contact element, which is preferably arranged on a bottom side of a module, and at least one contact surface, which is preferably arranged within the work surface, wherein the module-side contact element is configured to be placed on the contact surface, wherein the contact surface has a first contact point, wherein the module-side contact element has a second contact point, wherein the first contact point and the second contact point are configured to establish an electrical connection between the contact surface and the module-side contact element, wherein the

[0057] white ip | Patent & Legal PCT application Contact surface has a first fixing element and wherein the module-side contact element has a second fixing element, wherein the first fixing element in operative connection with the second fixing element is configured to magnetically fix the module-side contact element to the contact surface when the module-side contact element is placed on the contact surface, wherein the second contact point of the module-side contact element is configured to exert a counter-pressure on the first contact point of the contact surface while the module-side contact element is placed on the contact surface, wherein the second contact point is spring-loaded.

[0058] According to a further embodiment, the first contact point is essentially flat with the contact surface, wherein the surface of the first contact point is flush with the contact surface or only slightly recessed into the contact surface. The term "slightly recessed" means that the surface of the first contact point is preferably raised or recessed by less than 10 mm, more preferably by less than 5 mm, and most preferably by less than 1 mm from the surface of the contact surface and / or the surface of the working surface. According to this embodiment, the surface of the first contact point is only slightly recessed into the contact surface. This advantageously prevents or minimizes the accumulation of contaminants on the contact surface. As a result, both the contact surface and the working surface are easy to clean.The work surface and the contact surface are preferably also designed to be flat.

[0059] A flat or flush finish means that the first contact point is recessed into the surface in such a way that its surface facing the contact area is at the same level as the surface of the contact area or the surface of the work surface. This advantageously prevents or minimizes the accumulation of dirt on the contact surface, making it, as well as the work surface, easy to clean.

[0060] Particularly when using the work surface within a safety workbench or sterile workbench, this can advantageously ensure that particles, germs or contaminants remain on the contact surface only to a small extent, thus supporting sterile work in a sterile work area.

[0061] According to a further embodiment, the first fixing element with the contact surface is essentially planar, wherein the surface of the first fixing element is flush with the contact surface or only insignificantly recessed into the contact surface.

[0062] white ip | Patent & Legal PCT application is recessed, or wherein the first fixing element is designed as a fixing elevation, or wherein the first fixing element is designed as a fixing depression.

[0063] The term "insignificant" means that the surface of the first fixing element is preferably raised or recessed by less than 10 mm, more preferably by less than 5 mm, and most preferably by less than 1 mm from the surface of the contact surface and / or the surface of the work surface. This advantageously prevents or minimizes the accumulation of contaminants on the contact surface, making it, as well as the work surface, easy to clean.

[0064] Regarding the flat or flush finish, the same advantages arise as for the flat or flush finish of the first contact point with the contact surface.

[0065] A fixing feature is raised above the contact surface and does not finish flush with it, while a fixing recess is sunk into the contact surface and also does not finish flush with the contact surface.

[0066] The design of the first fixing element as a fixing protrusion or recess allows for a positive locking of the module-side contact element in the horizontal direction with respect to the work surface, thereby advantageously preventing slippage of the module-side contact surface and / or the module-side contact element during intended use. This advantageously ensures that the second contact point is held in a position corresponding to the first contact point, so that the electrical connection between the contact surface and the module-side contact element can be reliably established during intended use. It is evident that the module-side contact element must have a fixing recess into which the fixing protrusion of the contact surface engages positively.Similarly, the module-side contact element must have a fixing protrusion if the contact surface has a fixing recess. Combinations of fixing protrusions and fixing recesses are also conceivable, whereby the contact surface has at least one fixing protrusion and at least one fixing recess. This also applies to the module-side contact element. In combination with the magnetic fixing of the module-side contact element to the contact surface, this advantageously ensures that the module-side contact element is secured against both horizontal slippage and displacement during intended use.

[0067] white ip | Patent & Legal PCT application unintentional detachment from the contact surface is secured, whereby the module-side contact element can still be lifted by a user or an actuator, such as a robot arm.

[0068] A fixing feature or recess can, for example, be located only in the corner areas on the underside of the module-side contact element (point-like). The fixing feature or recess can also be arranged around the perimeter, meaning that the fixing feature or recess has, for example, a rectangular, circular, or polygonal shape.

[0069] A circumferential arrangement advantageously allows for an even more stable, form-fitting securing of the module-side contact element in the horizontal direction to the work surface, since the area available for securing between the fixing point and the fixing recess is increased compared to a point-shaped design.

[0070] The fixing protrusions arranged on the underside of the module-side contact element can be designed as spring-loaded pressure pieces that engage in fixing recesses of the contact surface. These spring-loaded pressure pieces can advantageously further increase the securing of the module-side contact element to the contact surface.

[0071] According to a further embodiment, the fixing protrusion is designed as a spacer element which is arranged to be reversibly positioned between the module-side contact element and the contact surface and to create a distance between the module-side contact element and the contact surface.

[0072] A spacer element is understood to be a means which causes a distance between the module-side contact element and the contact surface or the working surface, so that a distance is arranged between the module-side contact element and the contact surface or the working surface.

[0073] This allows a module to be positioned at different heights above the work surface. The distances can be adjusted discontinuously by stacking several spacer elements on top of each other according to the desired spacing.

[0074] Preferably, the spacers are identical in construction and designed to allow electrical connection. They are therefore to be used as intermediate elements.

[0075] white ip | Patent & Legal PCT application understanding, which are arranged between the contact surface and the module-side contact element.

[0076] According to a further embodiment, the first fixing element is designed as an electromagnet or a permanent magnet or a magnetic means, wherein the second fixing element is designed as an electromagnet or a permanent magnet or a magnetic means.

[0077] When, within the meaning of the invention, a (magnetic) fixing element is mentioned, this can be configured as an electromagnet, a permanent magnet, or a magnetic means. A magnetic means is understood here to be a means that is attracted by an electromagnet or a permanent magnet. For example, it can be a magnetic metal. According to a preferred embodiment, at least one of the fixing elements is configured as an electromagnet or a permanent magnet, and the other fixing element can be configured as an electromagnet, a permanent magnet, or a magnetic means.

[0078] According to one embodiment, the first and / or the second fixing element is designed as an electromagnet, wherein the magnetic attraction force is adjustable so that it is possible to switch between a fixing mode and a release mode.

[0079] A magnetic medium is defined as a medium that is attracted to an electromagnet or a permanent magnet. For example, it could be a magnetic metal.

[0080] The fixation of the module-side contact element to the contact surface by magnetic interactions advantageously eliminates the need for fixing elements that rise from or are recessed into the contact surface, thus facilitating the cleaning of the contact surface.

[0081] Preferably, magnetic fixing elements are arranged on the underside of the module and / or the work surface and / or the contact surface such that the spatial arrangement of the magnetic fixing elements determines the orientation of the module on the work surface. This advantageously ensures that the module is, or must be, placed in a predetermined orientation on the work surface during intended use, so that the module-side contact element can be positioned in the intended orientation on the contact surface. This allows

[0082] white ip | Patent & Legal PCT application advantageously also achieved that an electrical connection between the contact surface and the module-side contact element can be reliably established when the module-side contact element is placed on the contact surface.

[0083] According to one embodiment, the magnetic fixing elements have a defined polarity arrangement / polarity pattern, in particular a predetermined pattern of north and south poles. This advantageously ensures that the module only develops a sufficient magnetic attraction to the work surface and / or contact surface in the intended orientation, thus preventing or at least making incorrect orientation during module placement more difficult.

[0084] The magnetic attraction advantageously centers the module on the work surface if it is not perfectly aligned during placement. This facilitates the module's placement on the work surface by means of the magnetic attraction.

[0085] It may be provided that at least one magnetic fixing element is provided on the underside of the module and / or the work surface and / or the contact surface.

[0086] Preferably, a plurality of magnetic fixing elements are provided, arranged on the underside of the module and / or the work surface and / or the contact surface such that the spatial arrangement of the magnetic fixing elements determines the orientation of the module on the work surface. This advantageously ensures that the module is positioned in a predetermined orientation on the work surface during intended use, allowing the module-side contact element to be placed on the contact surface in the intended orientation. This, in turn, advantageously ensures that a reliable electrical connection can be established between the contact surface and the module-side contact element when the module-side contact element is positioned on the contact surface.

[0087] Preferably, at least one magnetic fixing element is provided per contact surface.

[0088] If a plurality of magnetic fixing elements are provided, the plurality of magnetic fixing elements can be arranged in a substantially grid-like pattern. Preferably, at least one of the magnetic fixing elements is arranged within a field of the grid. It can also be provided that the magnetic fixing elements

[0089] white ip | Patent & Legal PCT application are arranged in different grids, whereby the orientation of the module on the work surface is determined by the spatial arrangement of the magnetic fixing elements.

[0090] If a number of magnetic fixing elements are provided, it can be advantageously achieved that when placing the module, a rough, remote alignment is first achieved and then, especially when bringing it into contact, a centering of the module on the work surface is achieved by the magnetic attraction force if the module is not perfectly aligned during placement.

[0091] The magnetic attraction advantageously centers the module on the work surface if it is not perfectly aligned during placement. This makes placing the module on the work surface or contact surface easier.

[0092] Furthermore, it can be advantageously achieved that the module-side contact element is fixed to the contact surface via the magnetic fixing in such a way that the module-side contact element does not slip on the contact surface during intended use.

[0093] The magnetic fixation is preferably strong enough to attract the module and securely fix it to the work surface, but weak enough that a user or an actuator, such as a robot arm, can lift the module. The force with which the magnetic fixing elements attract each other is preferably in the range of 0.5 N to 10 N, more preferably in the range of 1 N to 8 N, and most preferably in the range of 1.5 N to 6 N.

[0094] According to one embodiment, a plurality of magnetic fixing elements are provided, wherein at least some of the magnetic fixing elements are designed as alignment elements with a lower magnetic attraction force and at least some further elements as holding elements with a higher magnetic attraction force. This advantageously ensures that the module is first aligned and centered during placement and subsequently reliably fixed to the work surface and / or contact surface during intended use.

[0095] According to one embodiment, at least one of the magnetic fixing elements is designed as an electromagnet, so that the magnetic attraction force can be specifically adjusted. This advantageously allows the module to be used for fixing.

[0096] white ip | Patent & Legal PCT application during intended use with increased magnetic attraction and can be released for lifting by a user or an actuator, such as a robot arm, with reduced magnetic attraction.

[0097] According to one embodiment, the module interface is configured to detect correct module placement via magnetic detection, in particular by means of a magnetic field-sensitive sensor. This advantageously ensures that the first contact point is only supplied with electrical voltage after correct placement has been detected, thus reducing the risk of an electrical accident by eliminating the need for an inactive contact point.

[0098] According to one embodiment, a plurality of magnetic fixing elements are arranged such that they form a module-dependent magnetic signature. This advantageously enables the identification of the module to be additionally or supplementarily supported by magnetic recognition as soon as the module is positioned on the work surface or contact surface.

[0099] According to a preferred embodiment, at least one of the fixing elements is designed as an electromagnet. The electromagnet is preferably switchable on and off, allowing switching between a fixing mode and a release mode. In fixing mode, the electromagnet is configured to magnetically fix the module to the work surface and / or contact surface. In release mode, the electromagnet is configured to reduce the magnetic fixation, allowing the module to be lifted by a user or an actuator, such as a robot arm. This advantageously ensures that the module is reliably fixed during intended use and can be selectively released when required.

[0100] According to a particularly preferred embodiment, the magnetic attraction force of the electromagnet is adjustable. This advantageously allows the magnetic fixation to be adapted to different modules and / or different placement conditions, so that the module can be held in place with increased magnetic attraction force during intended use and released with reduced magnetic attraction force for lifting by a user or an actuator, such as a robot arm.

[0101] According to one embodiment, the magnetic fixing elements are encapsulated and preferably flush with the surface of the work surface and / or contact surface.

[0102] white ip | Patent & Legal PCT application pending. This advantageously ensures that little or no soiling can accumulate in the area of ​​the magnetic fixing elements, and that the work surface and contact surface are easy to clean or disinfect.

[0103] According to another embodiment, the contact surface is designed to be reversibly arranged within the work surface or on an external module location.

[0104] An external module slot is defined as a contact surface that is not located at the same location as the work surface and, in particular, is situated outside a sterile workbench or safety cabinet. The ability to reversibly position the contact surface allows it to be removed from the work surface and placed in the external module slot, for example, for maintenance work. This facilitates maintenance or testing of modules or multi-holders connected to the module interface, eliminating the need for them to be located within the safety cabinet and thus enabling easy access for the user.

[0105] The ability to arrange the contact surface reversibly makes it advantageous to remove it from the work surface and place it in the external module space, e.g. for maintenance work.

[0106] The device according to the invention, in particular the module interface, the work surface or the multiple holder, can also be arranged outside a safety workbench.

[0107] For the purposes of this invention, the term "safety cabinet" also includes laboratory equipment enclosures, automated systems, or sample processing equipment. A module interface can also be located on a surface that is not the same as the work surface of a safety cabinet, but rather in a different location, for example, an automated system (e.g., an automated pipetting platform, an automated liquid handling system). This advantageously facilitates maintenance or testing of modules or multi-holders connected to or within the module interface, so that these do not need to be located inside the safety cabinet, thus allowing easy access for the user.

[0108] According to a further embodiment, the contact surface arranged within the work surface is designed to be lifted out of the work surface, preferably by an internal control unit, at least section by section.

[0109] white ip | Patent & Legal PCT Application An internal control unit is understood to be a control unit configured to actuate an actuator (e.g., a servo motor, pneumatic system, or hydraulic system) to lift the contact surface from the work surface so that it can be removed (e.g., for maintenance). The control unit may, but does not have to, be enclosed within the work surface.

[0110] Preferably, the internal control unit is configured to actuate a fixing element designed as an electromagnet in order to temporarily assist or release the fixing of the module. In particular, the internal control unit is configured to adjust the magnetic attraction force so that it can switch between a fixing mode and a release mode.

[0111] A reversible arrangement of the contact surface within the working area advantageously allows the contact surface to be replaced by another contact surface. Technical components, such as circuits, can be arranged below the contact surface, making them easily accessible for maintenance work, for example. It is advantageous that lifting the contact surface provides access to a component located below it, thus allowing access to technical components, such as circuits, for maintenance work, for example.

[0112] Maintenance work can be easily accessed.

[0113] According to a further embodiment, the contact surface is designed such that a manual pressure movement on the contact surface, in the direction of the work surface, causes the contact surface to be lifted at least partially from the work surface as soon as a pressure point is overcome. This advantageously ensures that the contact surface is lifted at least partially from the work surface after the pressure point has been overcome and can then be removed by the user. To reinsert the contact surface into the work surface, the process is carried out in reverse order (inserting the contact surface, pressing down until the pressure point is overcome, releasing the contact surface).

[0114] A manual pressure movement is understood to be a movement exerted by a user on the contact surface. This movement can be detected and processed by the internal control unit to induce appropriate reactions (such as switching off actuators), thus preventing the risk of accidents to the user caused by moving parts. This can advantageously achieve that

[0115] white ip | Patent & Legal PCT application: The risk of accidents to the user caused by moving parts is prevented by inducing a shutdown of actuators during manual pressure movement.

[0116] The manual pressing motion can be carried out until a pressure point is overcome. At this point, the contact surface is preferably lifted at least partially relative to the work surface by a spring-loaded mechanism, or lifted out of the work surface, and can then be removed by the user.

[0117] To reinsert the contact surface into the work surface, the process is carried out in reverse order (inserting the contact surface, pressing down until the pressure point is overcome, releasing the contact surface).

[0118] According to a further embodiment, the second contact point of the module-side contact element is configured to exert a counter-pressure on the first contact point of the contact surface while the module-side contact element is placed on the contact surface, wherein the second contact point is preferably spring-mounted.

[0119] A counter-pressure enables a constant connection between both contact surfaces, thus advantageously ensuring a constant galvanic connection between the two contact surfaces as long as the module-side contact element is placed on the contact surface.

[0120] The second contact point of the module-side contact element is preferably designed as a spring pin. This spring pin is tensioned by a mechanism that pushes it out from the underside of the module. In this sense, the second contact point can be considered spring-loaded. Alternative means to the spring pin are also conceivable. The essential requirement for the second contact point is that it touches the first contact point when the module is placed on the work surface.

[0121] When the module is placed on the work surface, the first contact point, located on the contact surface, exerts a force on the spring pin, pushing it towards the underside of the module. The weight of the placed module ensures that the spring pin remains in contact with the first contact point for as long as the module is on the contact surface or the work surface. This advantageously allows the second contact point to remain in contact with the first contact point for as long as the module is in contact with the first contact point.

[0122] white ip | Patent & Legal PCT application is placed on the contact surface or the working surface. This ensures an electrical or galvanic connection between the first contact point and the second contact point for as long as the module is placed on the contact surface or working surface. This allows the module to be controlled or supplied with electrical power via this connection.

[0123] The electrical or galvanic connection between the first and second contact points is maintained as long as the module is placed on the contact surface or work surface. This connection allows the module to be controlled or supplied with electrical power.

[0124] As explained above, the first contact point is recessed into the surface to create a flat or flush finish. This means that the surface facing the contact area is at the same level as the contact area or the work surface. This design effectively prevents or minimizes the accumulation of contaminants on the contact area, making it, along with the work surface, easy to clean. A cable connection would not offer such easy cleaning. Furthermore, this design ensures that the laminar airflow above the work surface is not disrupted by a raised first contact point, thus maintaining a sterile working environment.

[0125] The functional connection between the spring-loaded second contact point and the first contact point, as described above, further advantageously eliminates the need for cables to connect the module to the work surface. This significantly reduces the time-consuming process of connecting the module to the work surface via a cable.

[0126] The first and second contact points are preferably arranged parallel to each other or in a line. The arrangement of the first and second contact points shall be referred to herein as the first contact strip and second contact strip, which, in a top view of the contact surface, have a substantially rectangular shape.

[0127] According to a preferred embodiment, the second contact strip of the module-side contact element, which is arranged on the underside of the module, is rotatably mounted. Rotation of the second contact strip in a horizontal direction relative to the work surface is permitted.

[0128] white ip | Patent & Legal PCT application advantageously allows for more flexible adaptation of the second contact strip to the first contact strip. For example, a first contact strip could be rotated by an angle (e.g., 90°). Rotatability of the second contact strip ensures that the module can be placed on the contact surface and electrically connected to the work surface, regardless of its intended orientation.

[0129] It can also be provided that the first and / or second contact strip can assume discrete angular positions. The achieved angular setting can be indicated to the user via haptic feedback, which occurs when the user has rotated the first and / or second contact strip to a predefined discrete angular position.

[0130] The module or the multi-holder described below preferably has a module-side identification element, which is recognized by a recognition module described below. The module-side identification element serves to uniquely identify the module or the multi-holder. The module-side identification element can preferably be read when the first and second contact points are in contact with each other.

[0131] Preferably, once the module is placed on the work surface, its position and / or orientation on the work surface can be identified via an internal computing unit.

[0132] Preferably, after identification by the identification module, a plausibility check is carried out and only if the check is successful is the first contact point activated.

[0133] According to one embodiment, the module is authenticated before functions are activated.

[0134] According to one embodiment, the polarity of the BUS connection, in particular the control of the respective first contact points or the voltages applied across them, can be varied by the internal processing unit depending on the orientation of the module. This advantageously allows a module to be placed on the work surface in any orientation, without the user having to pay attention to the module's orientation.

[0135] white ip | Patent & Legal PCT application According to a further embodiment, the module is first recognized by an internal computing unit via the module-side contact element before the first contact point is subjected to an electrical voltage and thus becomes active.

[0136] This advantageously increases safety in handling, as the risk of an electrical accident is reduced by a non-active contact point.

[0137] The module can be detected or read via a minimum voltage or a module-side identification element (e.g., transponder, RFID chip, or equivalent). For electromagnetic detection of the module, the contact surface must have a suitable means to detect the module-side identification element and read the stored information.

[0138] According to another embodiment, the module interface has a module-side computing unit for processing data and / or a data transmission means for transferring data.

[0139] When the invention refers to a computing unit, this can be an internal computing unit and / or a module-side computing unit. The module-side computing unit is preferably configured to process data and / or transmit data via a data transmission means. The internal computing unit is preferably configured to process data and / or transmit data with the module-side computing unit. Communication between a module-side computing unit and an internal computing unit preferably occurs when the module-side contact element is placed on the contact surface. When the invention refers to an internal control unit, this is preferably configured to control an actuator to lift the contact surface from the work surface so that the contact surface can be removed from the work surface.

[0140] Preferably, a handshake takes place before power is supplied, i.e., the module is authenticated by the computing unit, in which identity, position and / or orientation are determined and then activation is granted or functions of the module are activated.

[0141] A module-side computing unit is located at the same position as the module-side contact element and serves to process data. The module-side computing unit is preferably designed for communication with the internal computing unit. This communication preferably occurs when the module-side contact element is placed on the contact surface. This advantageously allows the module to be controlled by a

[0142] white ip | Patent & Legal PCT Application. A computing unit, preferably an internal computing unit, can be identified, with the identification occurring via the electrical connection as soon as the module-side contact element is positioned on the contact surface or the working surface. This advantageously enables the computing unit to determine the type of module or multi-holder placed on the contact surface, thereby facilitating subsequent process steps. For example, a program can be paused until a required module or multi-holder is placed on the contact surface.

[0143] Data can be generated by the module's contact element or transferred to it (e.g., from the internal processing unit). Data can also be generated by a sensor device, in which case it is referred to as measurement data.

[0144] According to one embodiment, the module can be identified by a computing unit, preferably an internal computing unit, wherein the identification takes place via the electrical connection as soon as the module-side contact element is positioned on the contact surface or the working surface.

[0145] A data transmission means comprises any device that, in combination with the module-side contact element, enables the transmission of data to or from the module-side processing unit. This can be achieved, for example, via a galvanic connection (such as a bus connection) or via an electromagnetic connection (radio, optoelectronic transmission).

[0146] According to one embodiment, the polarity of the BUS connection, in particular the control of the respective first contact points or the voltages applied across them, can be varied by the internal processing unit depending on the orientation of the module. This advantageously allows a module to be placed on the work surface in any orientation, without the user having to pay attention to the module's orientation.

[0147] According to another embodiment, the module is first detected by an internal processing unit via the module-side contact element before the first contact point is energized and thus becomes active. This advantageously increases handling safety, as the risk of an electrical accident is reduced by an inactive contact point.

[0152] According to one embodiment, the safety workbench has three, four or more disks, the disks being arranged to be moved independently of each other.

[0153] This advantageously allows the safety workbench, and in particular the sterile work area, to be accessible from more than one side. Preferably, the sterile work area can be accessed from more than one side simultaneously (e.g., by two users working at the workbench in parallel).

[0154] white ip | Patent & Legal PCT application,) can be accessed. This allows the sterilization bench to be compact while still providing simultaneous access to the sterile work area for more than one user.

[0155] A biosafety cabinet is a device that provides a controlled environment to protect users, samples, and the surrounding area. It is commonly used in biology, medicine, and pharmaceuticals, particularly for work with infectious or toxic materials. HEPA filters and directed airflow create a sterile environment and prevent the spread of hazardous particles. Different types exist (e.g., Class I, II, III), depending on the required level of protection. Biosafety cabinets are specifically used for activities such as cell cultures, microbiological testing, or the handling of biological hazards. A biosafety cabinet may also include an automated sample handling system.

[0156] Sample handling machines are designed for the storage and / or transport of samples (e.g., biological material and / or chemicals).

[0157] Laminar airflow is a uniform, undisturbed movement of air in parallel layers without turbulence. In safety cabinets, it ensures a controlled, clean environment by removing particles, germs, or contaminants from the work area. The air typically flows vertically or horizontally through a HEPA filter to minimize contamination.

[0158] A sterile working environment is an area that is free of living microorganisms such as bacteria, viruses, and fungi. It is created to prevent contamination.

[0159] The laminar airflow creates a sterile workspace by delivering purified, particle-free air evenly and without turbulence. This air passes through a HEPA filter, which removes over 99.99% of particles, germs, and contaminants. The laminar flow prevents contaminated air from entering or being stirred up by movement within the workspace. This ensures that potential contaminants are continuously removed from the workspace, maintaining a sterile environment.

[0160] Air filtration through the upper main body is carried out depending on the desired protection class of the safety workbench.

[0169] According to another embodiment, the air recirculation channel is arranged within the first and / or second and / or a further, in particular a third and / or fourth, frame element.

[0170] This allows for the advantageous elimination of a double-walled back panel for returning air to the filter unit, as the frame elements perform this function. Consequently, the interior of the stere bench can be accessed from more than one side.

[0171] According to another embodiment, the disc is designed as a double disc, wherein the double disc encloses a cavity, wherein this cavity is designed as an air return channel.

[0172] This makes it advantageous that the air recirculation does not have to take place in one of the frame elements, and further advantageously, the interior can be viewed from several sides.

[0173] According to one embodiment, when the double disc is fully lowered, it establishes a connection to an air return channel of the lower main body, and this connection is closed as soon as the double disc is raised.

[0174] According to another embodiment, the upper main body is designed to be positioned on the lower main body and reversibly connected to the lower main body.

[0175] This advantageously allows the upper main body to be easily detached from the lower main body, for example, for maintenance or before transport. Preferably, the frame elements are designed such that they constitute the only mechanical connection between the upper and lower main bodies. More preferably, the frame elements can be connected to the lower main body via a plug-in connection.

[0176] white ip | Patent & Legal PCT Application A reversible connection between the upper main body and the lower main body means that the two bodies are connected to each other by some kind of detachable mechanical connection. Suitable connection methods are known to those skilled in the art. Preferably, the reversible connection is a detachable positive-locking connection (e.g., using screws). It is also conceivable that the detachable positive-locking connection is made by a click or plug connection.

[0177] According to another embodiment, the upper main body is arranged to rotate around the main longitudinal axis, while the lower main body does not rotate and remains stationary.

[0178] This makes it advantageous to provide the lower main body with electrical connections without requiring them to move during rotation.

[0179] In this embodiment, the upper and lower main bodies can be permanently connected or detachably connected. Alternatively, the upper main body can be placed on top of the lower one, with a circular rail system arranged between the two main bodies.

[0180] The rail system advantageously allows the upper main body to be mounted on the lower main body with minimal friction and to rotate on it. Furthermore, the lamellar design of the rail system advantageously ensures a sterile working environment inside the safety workbench.

[0181] According to another embodiment, the lower main body is designed to rotate, at least partially, around the main longitudinal axis. This advantageously allows the safety workbench, positioned in a room, to be flexibly rotated to permit user access to the interior from various angles.

[0182] According to a further embodiment, the lower main body has a working surface defined herein, which preferably has a contact surface defined herein.

Preferably, the retractable module can be retracted into the upper main body in such a way that it does not obstruct work inside. If necessary, the retractable module can be lowered or raised, preferably controlled by a computing unit, in particular by an internal computing unit enclosed within the safety workbench.

[0185] A computing unit is a device or system capable of processing data, typically consisting of a processor, (data) memory, and control logic.

[0187] An electromagnetic wave encompasses any wave of the electromagnetic spectrum that is suitable for sterilizing or optically detecting the interior.

[0188] For example, an electromagnetic wave could be a UV wave, which is typically used to sterilize the interior of workbenches before or after work is completed. Furthermore, an electromagnetic wave could be coherent light (laser) of different wavelengths.

[0189] According to another embodiment, the electromagnetic wave is designed to reduce the presence of active microorganisms within the interior in order to keep the interior germ-free.

[0190] According to another embodiment, the retractable module has a means for modulating the laminar airflow. For example, the retractable module can generate a laminar airflow or draw in air for filtering. For the retractable module to generate a laminar airflow, it is necessary that the purified air is directed into the retractable module via an air supply duct.

[0191] white ip | Patent & Legal PCT application. This makes it advantageous to generate additional air movements within the interior of the sterile workbench, in addition to the laminar airflow located at the disc.

[0192] According to a further embodiment, the lowerable module is preferably designed to be essentially ring-shaped, wherein the lowerable module has a detection unit which is configured to detect a work tool or module positioned in the interior.

[0193] This detection unit is preferably a laser module attached to the lowering module, which moves along the lowering module in a circular path around the main longitudinal axis and optically scans the interior of the sterilization bench to detect the position of modules or equipment within it. The detection unit can also be configured to recognize identifiers (e.g., QR codes).

[0194] A working tool includes, for example, consumables such as pipette tips, reaction vessels, buffers, etc.

[0195] According to another embodiment, the frame element has a guide rail which is designed to allow vertical movement of the lowerable module along the main longitudinal axis.

[0196] The guide rail is preferably fitted with a flexible cover in areas not occupied by the lowering module. This advantageously prevents the guide rail from becoming dirty.

[0197] According to another embodiment, the work surface is configured, at least in sections, to rotate at least partially around the main longitudinal axis. This advantageously allows work tools or modules positioned on the work surface to be rotated around the main longitudinal axis, for example, to minimize the distances that an actuator, such as a robot arm, has to travel.

[0198] It can also be provided that a central, circular area of ​​the work surface, whose center coincides with the main longitudinal axis, is not rotated, while a ring-shaped area around this central area can be rotated.

[0209] According to another embodiment, the disc is coated at least partially with an electrochromic material, and wherein the disc is preferably

[0210] white ip | Patent & Legal PCT application is impermeable to sterilizing electromagnetic radiation, especially UV radiation.

[0211] An electrochromic material is a material whose optical properties—especially its color or light transmission—can be reversibly changed by applying an electrical voltage. This occurs through an electrochemical reaction in which ions are added to or removed from the material, resulting in a change in its light absorption. Such materials are frequently used in applications like dimmable windows, mirrors, or displays because they allow for controlled adjustment to changing light conditions and promote energy efficiency.

[0212] By using an electrochromic material, it can be advantageously achieved that the interior can be shielded from light in order to protect light-sensitive equipment (e.g. light-sensitive chemicals) from light outside the interior.

[0213] The electrochromic material can preferably be manipulated by a computing unit, in particular an internal computing unit, to influence the light transmission.

[0214] According to further training, the pane is at least partially made of a thermochromic material. Thermochromic materials change their light transmission depending on the temperature (not electronically controlled).

[0216] According to another embodiment, the surface in the area of ​​the contact surface and / or the display element is designed to be flat or essentially forms a continuity with them in order to facilitate easy cleaning.

[0217] white ip | Patent & Legal PCT Application. The work surface is intended for preferred use in a safety workbench or an automated laboratory system. Accordingly, the device may also be referred to as a safety workbench work surface (hereafter abbreviated as: work surface). Since, as stated above, a "safety workbench" herein also includes laboratory equipment enclosures, automated systems, or sample processing facilities, the work surface may also be referred to as a laboratory equipment work surface, sample processing facility work surface, laboratory work surface, or laboratory workstation integrated module interface.

[0218] In order for the work surface in the safety workbench to be used, it is preferably designed in such a way that it is set up for complete positioning within the safety workbench, more precisely in the interior of the safety workbench.

[0219] As described above, a safety workbench is a device that provides a controlled environment to ensure the protection of users, samples, and the surrounding area. Safety workbenches are specifically used for activities such as cell cultures, microbiological testing, or the handling of biological hazards. The terms safety workbench and sterile workbench are synonymous in this context.

[0220] As described above, a work surface is understood to be an area located, for example, within a sterile workbench or safety cabinet. Equipment or objects necessary for cell culture experiments can be arranged on the work surface. Preferably, the work surface is made of a material (e.g., glass, plastic, metal) that is easy to clean and chemically stable, i.e., not attacked by acids or alkalis. The area above the work surface, in which the experiments are carried out, is referred to as the sterile work area.

[0221] At least one contact surface is arranged within the work area. Preferably, a plurality of contact surfaces are arranged side by side within a work area. Preferably, the contact surface is configured for an electrical connection with a module positioned on the contact surface.

[0222] According to a preferred embodiment, the surface is opaque in sections, wherein the opaque sections are not located at the same position as the transparent or semi-transparent sections. For example, the total area of ​​all opaque sections may be larger than the total area of ​​all transparent sections.

[0223] white ip | Patent & Legal PCT application. The majority of the work surface can be made from a millable material such as a metal or a plastic, with sections of the work surface thus manufactured being cut out into which the contact surfaces and / or display elements are embedded.

[0224] The use of a millable material advantageously allows for lower tolerances of the recesses and the contact surfaces and / or display elements embedded therein than if the working surface were essentially made of a transparent or semi-transparent material (e.g., glass).

[0225] Furthermore, the use of an opaque material advantageously allows for the formation of scattered light between the individual display elements.

[0226] A display element can essentially be formed from a transparent or semi-transparent material in which a light source (e.g., LEDs) is arranged. Preferably, a display element is arranged around a contact surface and marks the location on the work surface where the module, tool, or multi-holder is to be placed.

[0228] According to another embodiment, the display element is configured to display a color- and / or frequency-coded optical signal, which is designed for optical transmission of information.

[0229] In this way, information (e.g., actions to be taken during the experiment) can be displayed directly on the workspace in a clear and intuitive manner, which is advantageous for the user.

[0230] A transparent surface allows electromagnetic radiation, especially visible light, to pass through almost unimpeded, so that objects behind the surface remain clearly visible. The transmittance is typically above a defined threshold, depending on the application or wavelength. This design advantageously allows elements located below the work surface, such as assemblies or displays, to be seen through the surface.

[0231] White IP | Patent & Legal PCT Application: A semi-transparent surface allows electromagnetic radiation to pass through partially, while objects behind the surface remain diffusely or attenuated visible. The transmittance lies between transparency and opacity and is influenced, for example, by the specific material structure or surface finish.

[0232] According to another embodiment, opaque sections of the surface are designed to increase the contrast of the color-coded and / or frequency-coded optical signal.

[0233] According to a further embodiment, the work surface is coated, at least partially, with an electrochromic material. Preferably, the electrochromic material is arranged so that it has no contact with the surface, particularly with an interior space. For example, the work surface can be designed with at least two layers, with the electrochromic material arranged between the two layers. This design advantageously allows elements arranged below the work surface, such as assemblies or displays, to be visible as needed.

[0234] The surface of the work area can also be non-transparent. The work area is preferably made, at least in sections, of a chemically stable material that is resistant to acids and / or alkalis.

[0235] A display element is a device or component that presents information visually, optically, or graphically. When a display element is mentioned herein, it refers specifically to the display element located below the surface of the work area, which is designed to display a color-coded and / or frequency-coded optical signal. Independently of this, a module may have an optical or acoustic output element to convey information to a user, even if the module is not placed on or below the contact surface. It serves to communicate data, states, or signals to a user. In a technical context, it includes components such as screens (e.g., LCD, OLED), LEDs, segments, or other visual indicators that are controlled by electrical signals.

[0236] Display elements are frequently used in devices to present numerical, symbolic, or graphical information.

[0357] The multiple holder according to the invention (hereinafter also referred to as: holder) for positioning a work tool on a work surface, in particular on a contact surface, is designed for a

[0358] white ip | Patent & Legal PCT application. Preferred use is intended for use in a safety workbench or in automated laboratory systems. Accordingly, the holder can also be referred to as a safety workbench equipment holder, laboratory equipment holder, sample processing equipment holder, lab station holder, or lab station-integrated holder, or even as a "holder with module-side contact element".

[0359] The multi-holder system allows for a space-saving arrangement of equipment within a safety cabinet or laminar flow hood. Various types of equipment (e.g., consumables such as pipette tips, reaction vessels, centrifuge tubes, boxes, buffers, reservoirs, waste containers) can be placed on the same holder in a space-saving manner and in close proximity to one another. This effectively maximizes flexibility within a limited number of slots (contact surfaces) in the safety cabinet.

[0360] According to one embodiment, an interface for identifying the multi-holder is arranged on its underside. When an identification interface is mentioned herein, it refers to an interface through which identification data for identifying the multi-holder can be provided and / or read. The identification data can, in particular, be configured as an identifier or identification code. Preferably, the identification interface comprises a module-side identification element, especially a readable identification code, e.g., an RFID tag or an NFC tag. Additionally or alternatively, the multi-holder can be configured so that the identifier is detected via a recognition module, the recognition module preferably being configured to transmit a signal to the processing unit, preferably the internal processing unit.This interface is a computing unit, preferably an internal computing unit, for identifying the multiple bracket. The interface can include a recognition module as described above.

[0361] According to one embodiment, a second fixing element is arranged on the underside of the base, wherein the second fixing element is configured to fix the base in operative connection with a first fixing element arranged on the working surface or contact surface.

[0362] Preferably, the functional connection between the first fixing element and the second fixing element is designed such that the base is held in a defined position and / or orientation relative to the contact surface, in particular to ensure a

[0363] white ip | Patent & Legal PCT application to enable reproducible data exchange and / or a reproducible electrical connection via the module-side contact element.

[0364] The special design of the multi-holder allows tools to be arranged safely and efficiently on the work surface.

[0365] A tool holder describes a device that is designed to hold and store tools such as reagent tubes, bottles, or waste containers.

[0366] Preferably, the interaction between the first and second fixing elements ensures that the base is fixed in a defined position relative to the contact surface, and in particular, is secured against slippage in the horizontal direction. The second fixing element may have a fixing projection and / or a fixing recess that interacts correspondingly with a fixing recess or projection on the contact surface.

[0367] According to a preferred embodiment, the multiple holder for positioning a work tool on a work surface, in particular on a contact surface, comprises: a base which has at least one receiving recess for arranging and receiving a work tool holder, at least one work tool holder which is configured to receive the work tool, wherein a second fixing element is arranged on the underside of the base, wherein the second fixing element is configured to fix the base in operative connection with a first fixing element arranged on the work surface or contact surface.

[0368] According to a preferred embodiment, the multiple holder for positioning a tool on a work surface, in particular on a contact surface, comprises: a base which has at least one receiving recess for arranging and receiving a tool holder; at least one tool holder which is configured to receive the tool, wherein the receiving recess is configured to receive tool holders of different configurations; wherein a second fixing element is arranged on the underside of the base, wherein the second fixing element is configured to fix the base in operative connection with a first fixing element arranged on the work surface or contact surface; wherein a module-side contact element is arranged on the underside of the base, wherein the module-side contact element is used for an electrical connection with the contact surface or for data exchange between

[0369] white ip | Patent & Legal PCT application module side contact element and the contact surface or a computing unit is set up.

[0370] According to a preferred embodiment, the base has at least two receiving recesses, which are arranged next to each other and in which a working means can be arranged within each of the receiving recesses, which differs from a second working means which can be arranged in the adjacent receiving recess.

[0371] Differently designed instrument holders preferably have the same dimensions in the horizontal direction so that they can be inserted into the same receiving recesses, but may otherwise differ. For example, one instrument holder may be suitable for holding 15 ml test tubes, whereas a second instrument holder is designed for holding 50 ml test tubes and therefore must have different dimensions for the holes into which the test tubes are placed.

[0372] Data exchange refers to the transfer of information (data) between two entities, such as computers, modules, or programs, usually via defined interfaces and protocols. The goal is for both sides to be able to interpret the exchanged data correctly, which is why formats and rules are standardized.

[0373] Different types of data can be transferred between a processing unit, preferably an internal processing unit, and a module: control and status information, e.g., commands, states, error messages; measurement and sensor data (analog measured values ​​as digitized number sequences, e.g., temperature, pressure, voltage, fill levels); user data such as character strings, protocol or log data, configuration parameters, and table values;

[0374] Address and management data, e.g., memory addresses, register contents, or metadata for synchronization and error detection (checksums, sequence numbers). In embedded systems, this data exchange often takes place via buses (e.g., I). 2 C, SPI, CAN) or serial interfaces that precisely define which bit sequences have which meaning.

[0375] In particular, the data exchange serves to identify the module, the module-side contact element, or the multi-holder. When, within the meaning of the invention, reference is made to an identifier or an identification identifier, this refers to identification data used to identify a module, the module-side contact element, or a multi-holder.

[0376] white ip | Patent & Legal PCT Application Identification data is preferably short and unique and can be, for example, an ID number on an RFID or NFC tag, in a memory chip, as a MAC address, or as another means of identification. Preferably, the identifier is linked to metadata such as type, version, or serial number. For example, the multi-holder can have an identification identifier, such as a MAC address or another means of identifying the multi-holder. However, the data can also relate to physical quantities such as weight, fill levels, or temperature.

[0377] By determining these physical quantities via the module-side contact element, or the sensors encompassed by this element or the multi-holder, the processing unit can draw conclusions about, for example, the fill levels of the tool holders arranged within the base. For instance, a tool holder could be a waste container. When a certain weight is reached, a message can be generated indicating that the waste container needs emptying. This can also be indicated to the user via a visual signal on a defined display element.

[0378] As described above, the module-side contact element is a means which is arranged on the module or multi-holder and extends the module or multi-holder by further functions or features described herein.

[0379] In the simplest case, the module-side contact element on the underside of a module or a multi-holder is a module-side identification element, in particular a readable identification identifier (e.g. RFID tag, NFC tag).

[0380] Advantageously, the processing unit can use the identification code to determine the type of module or multi-holder placed on the contact surface, thus enabling subsequent process steps. For example, a program could be paused until a required module or multi-holder is placed on the contact surface.

[0381] According to one embodiment, the tool holder is designed to be horizontally connected to the base in a form-fitting manner.

[0382] A horizontal positive locking mechanism of the tool holder means that, when inserted into the receiving recess of the multi-holder, it is secured against slipping horizontally relative to the work surface during normal use. A horizontal positive locking mechanism also means that the multi-holder or a module is secured against slipping during normal use.

[0383] white ip | Patent & Legal PCT application. Slippage on the work surface is prevented. Preferably, the horizontal positive locking mechanism is designed so that the tool holder maintains its position in the receiving recess even when the base is transported by a movable actuator, thus ensuring that tools are held securely in place.

[0384] Preferably, the horizontal positive locking is achieved by corresponding contours of the receiving recess and a tool holder inserted into the receiving recess, so that the tool holder is secured against slipping in the horizontal direction during intended use, even in the event of vibrations and / or forces introduced by a user or a movable actuator.

[0385] According to one embodiment, the horizontal positive locking is achieved through a poka-yoke connection. This allows the user to insert the tool holder into the receiving recess only in the intended directions. This is relevant, for example, if the tool holder is designed in such a way that it can only be properly positioned on the base for the correct retention of tools.

[0386] A Poka-Yoke connection is a mechanical connection in which the geometry of the components is designed in such a way that incorrect joining or connection is structurally prevented or immediately recognizable.

[0387] A "Poka-Yoke connection" refers to a connection device with at least two corresponding connecting elements whose complementary geometry is designed in such a way that joining in an unintended orientation or with an unassigned counterpart is prevented by positive locking or is reliably made recognizable by a defined engagement or blocking mechanism.

[0388] In manufacturing and assembly technology, Poka-Yoke connections serve as preventive quality assurance by constructively eliminating assembly errors, reverse polarity or mix-ups of cables and assemblies.

[0389] A horizontal form-fit connection between the tool holder and the base, achieved through a Poka-Yoke mechanism, means that the tool holder can only be inserted into the base in a specific orientation. This effectively prevents incorrect insertion of the tool holder by the user.

[0390] white ip | Patent & Legal PCT application. Preferably, the Poka-Yoke connection is designed in such a way that a tool holder not intended for the receiving recess cannot be inserted into the receiving recess as intended, thus preventing confusion between differently designed tool holders.

[0391] According to one embodiment, at least one magnet or magnetic fixing (as defined herein) is arranged in the upper region of the base, which is configured to magnetically fix the tool holder to the base. This advantageously ensures that the tool holder is stably arranged on the base and cannot, for example, detach from the base due to vibrations.

[0392] Preferably, the magnet or magnetic fixing is designed to pull the tool holder inserted into the receiving recess into a defined end position on the base, so that the tool holder is positioned for a vertically form-fitting fixation by the click mechanism.

[0393] According to one embodiment, the tool holder and the base have a click mechanism designed to vertically secure the tool holder placed on the base. This creates a positive-locking connection that is more stable than magnetic fixation.

[0394] Preferably, the click mechanism is designed to hold the tool holder in a defined vertical position on the base, so that the tool holder is not unintentionally detached from the base by a movable actuator, even during transport of the base.

[0395] Preferably, the click mechanism provides haptic and / or acoustic feedback as soon as the tool holder is vertically and positively locked in place as intended. This advantageously allows the user to be informed of a successful positive lock or a successful connection between the tool holder and the base.

[0396] According to one embodiment, the tool holder is designed to accommodate at least two receiving recesses. This allows tool holders with different designs, adapted to different tools, to be advantageously arranged on the base. This means that the same tool holder can be selectively positioned in different receiving recesses on the base, so that

[0397] white ip | Patent & Legal PCT application. Work equipment can be placed in different areas of the work surface, especially on different contact surfaces, depending on the workflow.

[0398] Preferably, the at least two receiving recesses are designed in such a way that different tool holders can be arranged in defined grid positions within the base.

[0399] According to one embodiment, a magnetic means or a magnetic fixing (as defined herein) is arranged on at least one of the side surfaces of the base, wherein the magnetic means is configured to be contacted by an electromagnet arranged on a movable actuator for the purpose of transporting the base.

[0400] A movable actuator is understood to be, for example, a robot arm that is set up to transport work tools, modules, or the multiple holder across the work surface and place them, for example, on the contact surface.

[0401] Preferably, the magnetic means or magnetic fixing (as defined herein) is arranged on the side surface such that the movable actuator can contact the base for the purpose of transport between different contact surfaces of the work surface without touching the top of the base or the tool holder. Preferably, the transport takes place after the fixing of the base is released by the operative connection of the first fixing element and the second fixing element.

[0402] Preferably, a workflow protocol is provided which comprises a plurality of steps, wherein a first step involves placing the base on a first contact surface and a second step involves placing the base on a second contact surface. Individual steps can be performed on different sections of the work surface (as defined herein), in particular by the movable actuator transporting the base between the contact surfaces. By executing the workflow step by step, it is advantageously achieved that work materials are provided in a defined sequence and at defined locations.

[0403] According to one embodiment, a module-side contact element is arranged on the underside of the base. This module-side contact element implements the features described above. For example, it may be desirable that the multi-holder be connected via

[0404] white ip | Patent & Legal PCT application: the module-side contact element exchanges data with the contact surface or a computing unit, preferably an internal computing unit.

[0405] Preferably, user data such as protocol or log data and / or configuration parameters, which are assigned to a workflow, are transmitted via data exchange, in particular to allow the computing unit to take into account which tool holder and / or which tool is positioned on which contact surface, so that subsequent process steps are enabled.

[0406] In computer science, data refers to formalized, machine-readable representations of information, usually as digital strings of characters or bits, that can be stored, transmitted, and processed. They are encoded to allow for efficient communication, interpretation, and processing, typically in binary form. For module identification, data is used as a unique identifier, such as an ID number on an RFID tag or in a memory chip. This identification data is usually short, unambiguous, and often linked to metadata such as the module's type, version, or serial number.

[0407] Different features of the inventions described herein can interact synergistically. For example, the module interface, and / or work surface, and / or sensor device, and / or multi-holder defined herein can be arranged in a safety workbench defined herein to extend its functionality by the features of the corresponding partial invention.
