[0044] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0046] With the development of mechanization, pallet transportation has been widely used in the field of logistics and transportation. In pallet transportation, the goods are placed on pallets and reasonably stacked and fixed according to the characteristics of the goods and handling requirements to ensure stability during transportation.

[0047] However, when the pallet is in certain positions, such as when entering a manual operation area, it needs to be forced to stop. During the forced stop process, the heavy weight of the pallet and the cargo makes it difficult to stop the pallet reliably and stably.

[0048] For this reason, see Figure 1 and Figure 2 The present invention provides a stopping device having a first state. The stopping device includes a blocking member 10, a fixed shaft 20, and a limiting member 30. The blocking member 10 includes a blocking plate 11. The blocking plate 11 has a first surface A1 and a second surface A2 opposite to each other. The first surface A1 includes a first area D1 for contacting the member to be stopped. The blocking member 10 is rotatably connected to the fixed shaft 20 along the axial direction Y of the fixed shaft 20. In the first state, the blocking member 10 is arranged in contact with the limiting member 30, and the limiting member 30 is located on the side of the second surface A2 facing away from the first surface A1. In the first state, the limiting member 30 is located between the fixed shaft 20 and the first area D1 in the first direction X. The distance between the limiting member 30 and the first area D1 in the first direction X is less than the distance between the limiting member 30 and the fixed shaft 20 in the first direction X. The first direction X, the thickness direction Z of the blocking plate 11, and the axial direction Y of the fixed shaft 20 intersect with each other.

[0049] The stopping device provided in the embodiments of the present application is used to stop the movement of a member to be stopped. For example, the stopping device can be used to stop the sliding of the member to be stopped. When the member to be stopped slides in a specific direction, the stopping device is positioned in the sliding path of the member to be stopped, and the blocking plate 11 contacts the member to be stopped, thereby stopping the sliding of the member to be stopped. Alternatively, the stopping device can be used to stop the rotation of the member to be stopped. When the member to be stopped rotates about a specific axis, the stopping device is positioned in the rotation path of the member to be stopped, and the blocking plate 11 contacts the member to be stopped, thereby stopping the rotation of the member to be stopped.

[0050] Regarding the part to be stopped, taking the field of logistics as an example, in related technologies, technicians use pallets to transport goods. During the process of transporting goods on the pallet, the stopping device provided by the embodiment of the present application can be set at the position where the pallet needs to stop moving. The stopping device has at least a first state, that is, a state in which the stopping device contacts the part to be stopped and stops the part to be stopped. It is understandable that the stopping device should also have a second state, that is, a state in which the stopping device does not contact the part to be stopped and allows the part to move normally. Figure 1 and Figure 3 Schematic diagram. Under normal circumstances, the stop device is in the second state, and the stop member moves normally to complete its normal operation. When the stop member needs to stop moving, the stop device switches from the second state to the first state, and the stop member takes effect.

[0051] Specifically, the stopping device includes a blocking member 10 for contacting the member to be stopped, a fixed shaft 20 for connecting the blocking member 10 and fixing its position, and a limiting member 30 for limiting the position of the blocking member 10. During the motion trajectory of the member to be stopped, the blocking member 10 comes into contact with the member to be stopped, exerting a certain force on the member to be stopped, causing the member to stop moving. Accordingly, the member to be stopped will generate a reaction force on the blocking member 10. Therefore, a limiting member 30 is further provided to limit the blocking member 10. During the process of limiting the blocking member 10 by the limiting member 30, the force exerted by the limiting member 30 on the blocking member 10 is used to offset the impact force of the member to be stopped on the blocking member 10, so that the blocking member 10 can stably and reliably block the member to be stopped. In some embodiments, the stopping device also includes a base 60, on which the fixed shaft 20 and the limiting member 30 are both disposed.

[0052] The blocking member 10 includes a blocking plate 11 having a first surface A1 and a second surface A2 disposed opposite each other. The first surface A1 includes a first area D1 for contacting the member to be stopped. In a first state, the blocking member 10 is disposed in contact with a limiting member 30, with the limiting member 30 being located on the side of the second surface A2 facing away from the first surface A1. It will be appreciated that in the first state, the member to be stopped is located on one side of the first surface A1 of the blocking plate 11 and contacts the first area D1 on the first surface A1, while the limiting member 30 is located on one side of the second surface A2 of the blocking member 10 and contacts the blocking member 10. In other words, the member to be stopped and the limiting member 30 are located on opposite sides of the blocking member 10, respectively. This ensures that the force exerted by the limiting member 30 on the blocking member 10 is directly opposite to the direction of the impact force exerted by the member to be stopped on the blocking member 10, thereby reducing the probability of deflection of the blocking member 10 in the first state and improving the positional stability of the blocking member 10 in the first state.

[0053] To facilitate switching between the first and second states of the stopper device, the blocking member 10 is rotatably connected to the fixed shaft 20 along the axial direction Y of the fixed shaft 20. The switching between the first and second states is achieved during the rotation of the blocking member 10. In this arrangement, switching between the first and second states by rotation is equivalent to fixing one side of the blocking member 10 while deflecting the other side, thereby allowing the blocking member 10 to assume different positions. This can reduce the movable space of the blocking member 10 to a certain extent, thereby reducing the overall dimensions of the stopper device, reducing the footprint of the stopper device, and improving the applicability of the stopper device.

[0054] In the first state, the stopper 30 is located between the fixed axis 20 and the first area D1 in the first direction X. The distance between the stopper 30 and the first area D1 in the first direction X is less than the distance between the stopper 30 and the fixed axis 20 in the first direction X. The first direction X, the thickness direction Z of the blocking plate 11, and the axial direction Y of the fixed axis 20 intersect with each other. It is worth noting that, in practice, the object to be stopped should be an object with a predetermined volume in space and have three-dimensional dimensions in three-dimensional space. When the object to be stopped contacts the blocking plate 11, the contact position is mostly surface contact, that is, the first area D1 should be an area with a predetermined area. The blocking plate 11 should also include a non-contact area on the first surface A1 that is not in contact with the object to be stopped. The first area D1 and the non-contact area are offset in the first direction X.

[0055] In the above arrangement, the limit member 30, the blocking member 10 and the fixed axis 20 are projected onto a plane confirmed by the intersection of the first direction X and the thickness direction Z of the blocking plate 11. The main body of the blocking member 10 is arranged along the first direction X. The blocking member 10 has a first area D1 and a non-contact area along the first direction X. The limit member 30 is located between the fixed axis 20 and the first area D1 in the first direction X, that is, the projection of the limit member 30 on the blocking member 10 is in the non-contact area, and the fixed axis 20 is on the side of the limit member 30 away from the first area D1. The distance between the limit member 30 and the first zone D1 in the first direction X refers to the distance between the intersection point of the lines of action of the forces on which the limit member 30 is subjected to or exerts force (i.e., the simplified point of the force analysis of the limit member 30 in the mechanical model) and the intersection point of the lines of action of the forces on which the first zone D1 is subjected to or exerts force (i.e., the simplified point of the force analysis of the first zone D1 in the mechanical model). The distance between the limit member 30 and the fixed shaft 20 in the first direction X refers to the distance between the intersection point of the lines of action of the forces on which the limit member 30 is subjected to or exerts force (i.e., the simplified point of the force analysis of the limit member 30 in the mechanical model) and the intersection point of the lines of action of the forces on which the fixed shaft 20 is subjected to or exerts force (i.e., the simplified point of the force analysis of the fixed shaft 20 in the mechanical model). By making the distance between the limit member 30 and the first zone D1 in the first direction X smaller than the distance between the limit member 30 and the fixed shaft 20 in the first direction X, the principle of leverage can be utilized to offset the larger impact force between the part to be stopped and the blocking member 10 through the smaller force between the limit member 30 and the blocking member 10.

[0056] Specifically, taking the fixed axis 20 as the analysis point, the to-be-stopped member generates a relatively large impact force on the blocking member 10 at the first region D1, generating a first moment at the fixed axis 20 equal to the impact force multiplied by the distance between the first region D1 and the fixed axis 20 in the first direction X. Simultaneously, when the to-be-stopped member generates a relatively large impact force on the blocking member 10 at the first region D1, the limiting member 30 generates a second moment at the limiting member 30 on the fixed axis 20 equal to the limiting force multiplied by the distance between the limiting member 30 and the fixed axis 20 in the first direction X. The first torque should be equal to the second torque to achieve the effect of mutual offset. When the distance between the limit member 30 and the first zone D1 in the first direction X is smaller than the distance between the limit member 30 and the fixed axis 20 in the first direction X, the limiting force generated at the limit member 30 can be smaller than the impact force generated at the first zone D1, thereby achieving the effect of offsetting the larger impact force between the part to be stopped and the blocking member 10 with the smaller force between the limit member 30 and the blocking member 10, reducing the probability of the part to be stopped causing damage to the stopping device, ensuring the stopping effect of the stopping device on the heavy part to be stopped, and ensuring the stopping reliability of the stopping device on the part to be stopped.

[0057] In summary, in the embodiments of the present application, the stopping device is used to stop the movement of the object to be stopped. During the movement trajectory of the object to be stopped, the blocking member 10 comes into contact with the object to be stopped, exerting a certain force on the object to be stopped, thereby stopping the movement of the object to be stopped. Simultaneously, a limiting member 30 is provided to limit the position of the blocking member 10. During this process, the force exerted by the limiting member 30 on the blocking member 10 offsets the impact force of the object to be stopped on the blocking member 10, enabling the blocking member 10 to stably and reliably block the object to be stopped. Furthermore, by setting the distance between the limit member 30 and the first zone D1 in the first direction X to be smaller than the distance between the limit member 30 and the fixed axis 20 in the first direction X, the limit force generated at the limit member 30 can be smaller than the impact force generated at the first zone D1, thereby achieving the effect of offsetting the larger impact force between the part to be stopped and the blocking member 10 with the smaller action force between the limit member 30 and the blocking member 10, reducing the probability of the part to be stopped causing damage to the stopping device, ensuring the stopping effect of the stopping device on the heavy part to be stopped, and ensuring the stopping reliability of the stopping device on the part to be stopped.

[0058] In one embodiment, see Figures 1 to 5 The blocking member 10 further includes a reinforcing plate 12 connected to the second surface A2 of the blocking plate 11. In the first state, along the thickness direction Z of the blocking plate 11, the stopper 30 contacts an end of the reinforcing plate 12 facing away from the second surface A2, thereby spacing the stopper 30 from the second surface A2.

[0059] To enhance the strength of the blocking member 10, a reinforcing plate 12 is provided on the second surface A2 of the blocking member 10. Along the thickness direction Z of the blocking member 11, the reinforcing plate 12 is larger than the size of the blocking member 11. The provision of the reinforcing plate 12 enables the blocking member 11 to withstand greater forces acting along the thickness direction Z of the blocking member 11. In a first state, the stopper 30 contacts the end of the reinforcing plate 12 facing away from the second surface A2, preventing the stopper 30 from contacting the second surface A2. In other words, in the first state, the stopper 30 contacts the reinforcing plate 12, while the member to be stopped contacts the blocking member 11. The blocking member 10 acts as a clamp between the stopper 30 and the member to be stopped. The provision of the reinforcing plate 12 and the blocking plate 11 enhances the shear strength of the blocking member 10 in the thickness direction Z of the blocking member 11, reducing the probability of shear damage to the blocking member 10 caused by the forces of the stopper 30 and the member to be stopped.

[0060] In one embodiment, in the first state, along the thickness direction Z of the blocking plate 11 , the blocking plate 11 and the fixed shaft 20 are both spaced apart from the limiting member 30 , and the blocking plate 11 and the fixed shaft 20 are on the same side of the limiting member 30 . The locking plate 11 and the fixed shaft 20 are spaced apart from the limiter 30 so that the points at which the limiter 30 and the fixed shaft 20 exert their forces on the blocking member 10 are spaced apart in the thickness direction Z of the blocking plate 11. That is to say, there is a deviation between the points of action of the force exerted by the limiter 30 on the blocking member 10 and the force exerted by the fixed shaft 20 on the blocking member 10. Under the action of this deviation, a certain torque will be caused on the blocking member 10 between the two forces, so that the blocking member 10 is not simply subjected to shear forces in two directions. The torque generates a certain stress on the blocking member 10 between the points of action of the two forces, thereby achieving a buffering change in the internal stress of the part of the blocking member 10 between the points of action of the two forces, avoiding the formation of stress mutations inside the blocking member 10, and thus improving the use strength and service life of the blocking member 10.

[0061] In one embodiment, the stopper 30 extends along the axial direction Y of the fixed shaft 20. A plurality of reinforcing plates 12 are provided, and the plurality of reinforcing plates 12 are spaced apart along the axial direction Y of the fixed shaft 20. The stopper device further includes a buffer member 40, which is sleeved on the fixed shaft 20 and fixedly connected to the plurality of reinforcing plates 12.

[0062] During actual use, since the stopped member usually has a larger size in the axial direction Y of the fixed shaft 20, in order to make the blocking plate 11 have uniform blocking strength, the limiting member 30 is extended along the axial direction Y of the fixed shaft 20, and multiple reinforcing plates 12 are arranged at intervals along the axial direction Y of the fixed shaft 20, so that the limiting member 30 can uniformly limit and support the blocking plate 11 in the axial direction of the fixed shaft 20.

[0063] When the fixed shaft 20 and the blocking member 10 are rigidly connected, a large impact will be generated at the connection between the blocking member 10 and the fixed shaft 20, which is not conducive to the connection between the two. In view of this, the stopping device includes a buffer member 40, which is sleeved on the fixed shaft 20 and fixedly connected to the multiple reinforcing plates 12. When the impact force of the blocking member is transmitted to the buffer member 40, the buffer member 40 and the fixed shaft 20 are not rigidly connected. Because the buffer member 40 is only sleeved on the fixed shaft 20, the impact force transmitted between the buffer member 40 and the fixed shaft 20 can be reduced, thereby reducing damage to the fixed shaft 20 and extending the service life of the fixed shaft 20.

[0064] In one embodiment, the buffer member 40 and the fixed shaft 20 are slidably disposed along the axial direction Y of the fixed shaft 20. When the impact force is not transmitted in the radial direction of the fixed shaft 20, the buffer member 40 will tend to slide along the axial direction of the fixed shaft 20. If relative sliding between the buffer member 40 and the fixed shaft 20 is allowed, the impact force can be dissipated through relative sliding, thereby reducing the impact force. Therefore, in some embodiments, the buffer member 40 and the fixed shaft 20 are slidably disposed along the axial direction Y of the fixed shaft 20.

[0065] In one embodiment, the structure and connection method of the buffer member 40 are as follows: the reinforcement plate 12 of the blocking member 10 is rotatably connected to the fixed shaft 20. The reinforcement plate 12 is provided with a connection hole 121, through which the fixed shaft 20 is inserted. The buffer member 40 is a circular tubular structure, which is sleeved on the fixed shaft 20 and also inserted into the connection hole 121. This perforation method can simply and reliably achieve the rotational connection and the sleeved connection of the buffer member 40 with the fixed shaft 20.

[0066] In one embodiment, the contact arrangement between the stopper 30 and the blocking member 10 is configured as a circular rod-shaft structure, and the reinforcing plate 12 is provided with a connecting groove 122 at the contact position of the stopper 30. The connecting groove 122 is configured as a U-shaped arc groove with an opening on one side, and the stopper 30 can enter and exit the connecting groove 122 through the opening. When the stopper 30 contacts the reinforcing plate 12, the stopper 30 is located within the connecting groove 122, which can effectively limit the relative position relationship between the stopper 30 and the reinforcing plate 12 and prevent the stopper 30 and the reinforcing plate 12 from shifting during the contact process.

[0067] Furthermore, a first arc surface is formed at the bottom of the connecting groove 122, and a second arc surface is formed at the groove opening of the connecting groove 122. The first arc surface and the second arc surface are smoothly connected, and the axis at the center of the first arc surface and the axis at the center of the second arc surface are located on both sides of the groove side wall of the connecting groove 122. The provision of the second arc surface can provide a certain guidance for the position limiting member 30 to enter and exit the connecting groove 122, so that the position limiting member 30 can enter and exit the connecting groove 122 conveniently and accurately. The provision of the first arc surface makes the contact between the position limiting member 30 and the reinforcing plate 12 smooth, and there is contact between the side wall of the position limiting member 30 and the side wall of the connecting groove 122, and the acting force is diverged outward along the radial direction of the first arc surface and then transmitted to the interior of the reinforcing plate 12, so that the force inside the reinforcing plate 12 is uniform, and the situation that the reinforcing plate 12 is damaged and deformed due to excessive force in some parts and insufficient force in some parts inside the reinforcing plate 12 is avoided.

[0068] In one embodiment, the stopping device further includes a power assembly 50, which includes a rotating member 51 and a transmission member 52 connected between the rotating member 51 and the blocking member 10. The transmission member 52 is movably connected to the rotating member 51, and / or the transmission member 52 is movably connected to the blocking member 10.

[0069] The power assembly 50 provides power for switching the integral stopper between the first and second states. The power assembly 50 includes a rotating member 51 that can rotate along its own axis and a transmission member 52 connected between the rotating member 51 and the blocking member 10. The rotation of the rotating member 51 drives the displacement of the transmission member 52, thereby causing the blocking member 10 to move. Within the constraints of the fixed shaft 20, the blocking member 10 rotates about the axial direction Y of the fixed shaft 20.

[0070] In order to prevent the impact force from causing damage to the transmission member 52 and the rotating member 51, the transmission member 52 and the rotating member 51 are set to be movably connected, and / or the transmission member 52 and the blocking member 10 are set to be movably connected, so that relative movement is allowed between the blocking member 10, the transmission member 52 and the rotating member 51 to alleviate the impact force.

[0071] Specifically, in one embodiment, the rotating member 51 is provided with a first connection portion, and the transmission member 52 is provided with a second connection portion. One of the first connection portion and the second connection portion includes a first cavity, and the other includes a first rotating member. The first rotating member is at least rotatably located within the first cavity, and the inner wall of the first cavity and the first rotating member both include spherical structures. Through the connection between the first rotating member and the first cavity, the rotating member 51 and the transmission member 52 can rotate relative to each other within a certain angle and deviate relative to each other by a certain distance within a space. The relative movement of the rotating member 51 and the transmission member 52 can effectively mitigate impact forces.

[0072] Similarly, a third connecting portion is provided on the transmission member 52, and a fourth connecting portion is provided on the blocking member 10. One of the third connecting portion and the fourth connecting portion includes a second cavity, and the other includes a second rotating member. The second rotating member is at least partially rotatably located in the second cavity, and the interior of the second cavity and the second rotating member both include a spherical structure.

[0073] In one embodiment, the transmission member 52 includes an adjustment rod 523 and a first connecting rod 521 and a second connecting rod 522 connected at both ends of the adjustment rod 523. The adjustment rod 523 is provided with a first threaded portion and a second threaded portion at both ends, respectively. The first threaded portion is threadedly connected to the first connecting rod 521, and the second threaded portion is threadedly connected to the second connecting rod 522. The first threaded portion and the second threaded portion have opposite rotation directions.

[0074] To adjust the transmission distance between the rotating member 51 and the blocking member 10, the transmission member 52 is configured with an adjustable length. By threading the adjustment rod 523 with the first connecting rod 521 and the second connecting rod 522, the transmission member 52 is integrated and its length can be adjusted. Furthermore, to facilitate efficient adjustment, the first and second threaded portions rotate in opposite directions. When the adjustment rod 523 rotates in a specific direction, the first and second connecting rods 521, 522 can move closer together to shorten the length of the transmission member 52, or move farther apart to extend the length of the transmission member 52.

[0075] In one embodiment, to enable the blocking member 10 to quickly reach the position of the first stop mechanism state under the action of the transmission member 52, the transmission member 52 is connected to the reinforcing plate 12. The reinforcing plate 12 is provided with a second area D2 to which the transmission member 52 is connected. In a plane formed by the intersection of the first direction X and the thickness direction Z of the blocking plate 11, the distance between the second area D2 and the fixed axis 20 is smaller than the distance between the first area D1 and the fixed axis 20. In this arrangement, the transmission member 52 is connected to the reinforcing plate 12, which can prevent the blocking plate 11 from directly impacting the transmission member 52. The distance between the second zone D2 and the fixed axis 20 is smaller than the distance between the first zone D1 and the fixed axis 20, which means that the distance between the intersection point of the force lines of force applied to or exerted on the second zone D2 (i.e., the simplified force analysis point of the second zone D2 in the mechanical model) and the intersection point of the force lines of force applied to or exerted on the fixed axis 20 (i.e., the simplified force analysis point of the fixed axis 20 in the mechanical model) is smaller than the distance between the intersection point of the force lines of force applied to or exerted on the first zone D1 (i.e., the simplified force analysis point of the first zone D1 in the mechanical model) and the intersection point of the force lines of force applied to or exerted on the fixed axis 20 (i.e., the simplified force analysis point of the fixed axis 20 in the mechanical model), so that the shorter displacement of the second zone D2 can be converted into a longer displacement of the first zone D1, so that the blocking member 10 can be quickly moved to the position in the first state of the stopping device under the action of the transmission member 52.

[0076] In one embodiment, considering the force direction and bearing strength of the reinforcing plate 12, the reinforcing plate 12 is arranged in an L-shape on the plane formed by the intersection of the first direction X and the thickness direction Z of the blocking plate 11. The line connecting the connecting groove 122 and the connecting hole 121 is the long side, and the line connecting the second area D2 and the connecting hole 121 is the short side. Within a predetermined radial area centered on the connecting hole 121, the volume of the portion of the connecting hole 121 facing away from the connecting groove 122 is greater than the volume of the portion of the connecting hole 121 facing toward the connecting groove 122. Furthermore, the volume of the portion of the connecting hole 121 facing away from the second area D2 is greater than the volume of the portion of the connecting hole 121 facing toward the second area D2. In this arrangement, more material is placed in locations within the reinforcing plate 12 subject to greater force to enhance its strength, while less material is placed in locations within the reinforcing plate 12 subject to less force to reduce its volume and thus its cost.

[0077] In one embodiment, the rotating member 51 includes a rotating shaft 511 extending in the axial direction Y of the fixed shaft 20, and a rotating disk 512 fixedly connected to the circumference of the rotating shaft 511. The transmission member 52 is connected to the rotating disk 512. In the radial direction of the fixed shaft 20, the transmission member 52 is spaced apart from the rotating shaft 511; in the axial direction Y of the fixed shaft 20, the transmission member 52 and the rotating disk 512 partially overlap. For example, the rotating member 51 can be configured as a motorized roller. In other embodiments, the rotating member 51 can also be driven by a pneumatic cylinder, an electric cylinder, or a gear motor.

[0078] To facilitate connection between the transmission member 52 and the rotating member 51 and to limit the range of motion between the transmission member 52 and the rotating member 51, the transmission member 52 is connected to the rotating disk 512. Along the radial direction of the fixed shaft 20, the transmission member 52 and the rotating shaft 511 are spaced apart to prevent interference between the transmission member 52 and the rotating shaft 511, ensuring smooth power transmission. Along the axial direction Y of the fixed shaft 20, the transmission member 52 and the rotating disk 512 partially overlap. When the transmission member 52 deviates relative to the rotating disk 512, the rotating disk 512 can provide a certain degree of positioning for the displacement of the transmission member 52, thereby limiting the range of motion between the transmission member 52 and the rotating member 51.

[0079] In one embodiment, in order to control the rotation angle of the rotating member 51 so that the rotation angle of the rotating member 51 adapts to the rotation angle of the blocking member 10, the power assembly 50 further includes a control disk 53 and a sensing switch 54. A sector disk having a preset central angle is protruded from the outer periphery of the control disk 53, and the sector disk and the sensing switch 54 sense each other. One of the sensing switch 54 and the sector disk is fixed relative to the rotating member 51, and the other rotates synchronously with the rotating disk 512. The sensing switch 54 can cut off or connect the power to the power assembly 50. It can be understood that the sector disk of the preset angle corresponds to the rotation angle of the blocking member 10. When the blocking member 10 rotates to contact the limit member 30, the sensing switch 54 can sense the sector disk to cut off the power to the power assembly 50.

In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist. The present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
