Abstract
Description
Technical Field
[0001] This invention relates to the field of fluid transport technology, and in particular to a pipe clamp and a transport pipeline. Background Technology
[0002] Flexible tubing made of plastic or rubber is widely used in medical, pharmaceutical, biopharmaceutical, food and beverage, and other environments. During fluid transport through flexible tubing, tubing clamps are typically used to block fluid flow; however, existing ratchet-equipped clamps have the following drawbacks:
[0003] 1. The hinge between the first and second components on the pipe clamp needs to be achieved through a rotating shaft and an end cap. Both the first and second components are hinged to the rotating shaft, and the end cap can extend into the rotating shaft and engage with it, thereby limiting the axial position of the first and second components. This makes the installation of the first and second components require multiple steps, which is inconvenient and involves many parts with poor integration.
[0004] 2. Pipe clamps tend to release at inopportune or undesirable times, requiring additional straps or ties to tighten them and prevent accidental opening. Pipe clamp assembly and disassembly are inefficient and have high manufacturing costs.
[0005] Therefore, how to provide a pipe clamp and conveying pipeline that can solve at least one of the above-mentioned technical problems is a problem faced by those skilled in the art. Summary of the Invention
[0006] The purpose of this invention is to provide a pipe clamp that can achieve hinged connection through the self-structure of the first and second clamping arms, without the need for other auxiliary connecting parts, and has the advantages of simple installation steps and strong integration. Additionally, a delivery pipeline including the above-mentioned pipe clamp is provided.
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] In a first aspect, the present invention provides a pipe clamp, including a first clamping arm, a second clamping arm, and a locking member for connecting the first clamping arm and the second clamping arm to form a strip-shaped clamping channel;
[0009] One of the first clamping arm and the second clamping arm has a first hinge end, and the other has a second hinge end;
[0010] The first hinge end has two rotating shafts on both sides, and the end face of the rotating shaft has a beveled cut;
[0011] The second hinge end is recessed with a mounting groove for the first hinge end to extend into and has an insertion hole for hinged with the rotating shaft. The surface of the second hinge end facing the first hinge end is recessed with an oblique groove for guiding the rotating shaft to the insertion hole.
[0012] Furthermore, the first hinge end includes two first sidewalls arranged at relative intervals, and each of the two first sidewalls facing away from each other is connected to a pivot.
[0013] Furthermore, the second hinge end includes two relatively spaced second sidewalls, with the mounting groove formed between the two second sidewalls, the insertion hole provided on the second sidewall, and the inclined sliding groove recessed on the surface of the second sidewall facing the first hinge end.
[0014] Furthermore, the inclined groove extends from the end of the second sidewall to the insertion hole, and the depth of the inclined groove gradually increases in a direction that gradually moves away from the insertion hole.
[0015] Furthermore, the extension direction of the inclined groove is parallel to the length direction of the second rib plate on the second clamping arm used to clamp the flexible tube.
[0016] Furthermore, the first clamping arm includes a first clamping section, the second clamping arm includes a second clamping section, one of the first clamping section and the second clamping section is connected to the first hinge end, and the other is connected to the second hinge end;
[0017] The first clamping section includes a first rib, and the second clamping section includes a second rib corresponding to the first rib. The first rib and the second rib are used to clamp the flexible tube.
[0018] Furthermore, the first clamping arm and the second clamping arm are made of non-metallic materials.
[0019] Furthermore, the edges of both the first and second clamping arms are smoothly transitioned.
[0020] Furthermore, a first through hole is provided at the end of the first clamping arm away from the end that is hinged to the second clamping arm, and the locking member slides in cooperation with the first through hole along the first direction;
[0021] The second clamping arm has a second through hole recessed at the end opposite to the first clamping arm. The locking member slides in the second through hole along the second direction. The second direction has an angle with the first direction. The second through hole has a plurality of protrusions distributed along the second direction for engaging with the locking member.
[0022] Secondly, the present invention also provides a conveying pipeline, including the pipe clamp described in the above-described scheme.
[0023] The pipe clamp and conveying pipeline provided by this invention can produce the following beneficial effects:
[0024] When installing the above-mentioned pipe clamp, first align the protrusions on both sides of the first hinge end with the oblique groove of the second hinge end. Under the guidance of the oblique groove, guide the protrusions to the insertion hole. At this time, the first hinge end gradually enters the mounting groove. Since the end face of the protrusion has an oblique cut, the end face size of the protrusion is reduced, making it easier for the protrusion to be inserted into the insertion hole and hinged with the insertion hole. When using the above-mentioned pipe clamp, first open the first clamping arm and the second clamping arm, place the flexible tube between the first clamping arm and the second clamping arm, and then fasten the first clamping arm and the second clamping arm and lock it with the locking device. A clamping channel for clamping the flexible tube is formed between the first clamping arm and the second clamping arm, realizing the flow blocking function.
[0025] Compared with the prior art, the pipe clamp provided by the first aspect of the present invention can be hinged through the structure of the first clamping arm and the second clamping arm. Specifically, it is only necessary to push the protrusion into the insertion hole, without the need for other auxiliary connecting parts. It has the advantages of simple installation steps and strong integration.
[0026] The delivery pipeline provided by the second aspect of the present invention has the pipe clamp provided by the first aspect of the present invention, thereby having all the beneficial effects of the pipe clamp provided by the first aspect of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0058] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0059] A first aspect of the present invention provides a pipe clamp, such as Figures 1 to 6 As shown, it includes a first clamping arm 1, a second clamping arm 2, and a locking member 3 for connecting the first clamping arm 1 and the second clamping arm 2 to form a strip-shaped clamping channel 4; one of the first clamping arm 1 and the second clamping arm 2 has a first hinge end 11, and the other has a second hinge end 21; the first hinge end 11 has a rotating shaft 111 on both sides, and the end face of the rotating shaft 111 has a beveled cut 1111; the second hinge end 21 is recessed with a mounting groove 211 for the first hinge end 11 to extend into and has an insertion hole 2121 for hinged with the rotating shaft 111, and the surface of the second hinge end 21 facing the first hinge end 11 is recessed with a beveled groove 2122 for guiding the rotating shaft 111 to the insertion hole 2121.
[0060] by Figure 2 Taking an example, the first clamping arm 1 has a first hinge end 11, and the second clamping arm 2 has a second hinge end 21. The first hinge end 11 and the second hinge end 21 are hinged to achieve rotation of the first clamping arm 1 relative to the second clamping arm 2. (Reference) Figure 3 and Figure 4 The end face of the rotating shaft 111 has a beveled notch 1111, which reduces the size of the end face of the rotating shaft 111. (Refer to...) Figure 5 and Figure 6The second hinge end 21 has a recessed oblique groove 2122 on its surface facing the first hinge end 11. The rotating shaft 111 can preferentially enter the oblique groove 2122 and be aligned with the insertion hole 2121 under the guidance of the oblique groove 2122. Since the end face of the rotating shaft 111 has an oblique cut 1111, it is convenient to connect the first hinge end 11 and the second hinge end 21. The operation is convenient and labor-saving, and no other auxiliary connecting parts need to be installed, which has strong integration.
[0061] The aforementioned oblique cut 1111 can be regarded as being formed by obliquely cutting off a portion from the end face of the rotating shaft 111.
[0062] In some embodiments, such as Figure 3 and Figure 4 As shown, the first hinge end 11 includes two first sidewalls 112 that are spaced apart from each other. Each of the two first sidewalls 112 is connected to a rotating shaft 111 on opposite sides. The rotating shafts 111 can be hinged one-to-one with the insertion holes 2121 on the second hinge end 21 to achieve stable rotation of the first clamping arm 1 relative to the second clamping arm 2.
[0063] It is understandable that the two rotating shafts 111 mentioned above are set coaxially.
[0064] Of course, in some other embodiments, the two first sidewalls 112 may also have an integral structure to form a hinge block, with a pivot 111 connected to each side of the hinge block.
[0065] In some embodiments, such as Figure 5 and Figure 6 As shown, the second hinge end 21 includes two relatively spaced second sidewalls 212, and a mounting groove 211 is formed between the two second sidewalls 212. The first hinge end 11 can extend into the mounting groove 211. Insertion holes 2121 are provided on both second sidewalls 212, and the two rotating shafts 111 can be hinged to the two insertion holes 2121 one by one.
[0066] Among them, such as Figure 5 and Figure 6 As shown, the surfaces of the two second sidewalls 212 facing the first hinge end 11 are respectively provided with inclined sliding grooves 2122, so that the two rotating shafts 111 can slide into the two insertion holes 2121 through the inclined sliding grooves 2122.
[0067] In some embodiments, such as Figure 5As shown, the inclined groove 2122 extends from the end of the second side wall 212 to the insertion hole 2121. The depth of the inclined groove 2122 gradually increases in the direction that gradually moves away from the insertion hole 2121, so that the rotating shaft 111 can enter the inclined groove 2122 more easily. As the rotating shaft 111 gradually approaches the insertion hole 2121, the depth of the inclined groove 2122 gradually decreases, thereby guiding the rotating shaft 111 into the insertion hole 2121.
[0068] In some embodiments, such as Figure 5 As shown, the extension direction of the inclined groove 2122 is parallel to the length direction of the second rib 221 on the second clamping arm 2 for clamping the flexible tube 5, so that when the user holds the second clamping arm 2, he can push the first hinge end into the insertion hole 2121 along the length direction of the second rib 221.
[0069] In some embodiments, such as Figure 4 and Figure 5 As shown, the first clamping arm 1 includes a first clamping section 12, and the second clamping arm 2 includes a second clamping section 22. The first clamping section 12 is connected to a first hinge end 11, and the second clamping section 22 is connected to a second hinge end 21. The first clamping section 12 and the second clamping section 22 are used to fasten together to form a strip-shaped clamping channel 4.
[0070] Specifically, such as Figure 4 and Figure 5 As shown, the first clamping section 12 includes a first rib 121, and the second clamping section 22 includes a second rib 221 corresponding to the first rib 121. The first rib 121 and the second rib 221 are used to fasten and clamp the flexible tube 5.
[0071] In addition, the first clamping section 12 also includes a top plate 122, and a first rib 121 is connected to the bottom surface of the top plate 122 and forms a clamping structure with a T-shaped cross-section. The second clamping section 22 also includes a bottom plate 222, and a second rib 221 is connected to the top surface of the bottom plate 222 and forms a clamping structure with a T-shaped cross-section.
[0072] In at least one embodiment, the first rib 121 and the top plate 122 have an integral structure, and the second rib 221 and the bottom plate 222 have an integral structure.
[0073] In some embodiments, the first clamping arm 1 and the second clamping arm 2 are made of non-metallic materials.
[0074] It is made of thermoplastic engineering resins such as polypropylene, polyurethane, polyamide-66, and polyoxymethylene.
[0075] In some embodiments, the edges of the first clamping arm 1 and the second clamping arm 2 are smoothly transitioned to avoid scratching or puncturing the user during use, making the use process safer.
[0076] In some embodiments, the first clamping arm 1 has a first through hole 13 at the end opposite to the hinged end of the second clamping arm 2, and the locking member 3 slides in the first through hole 13 along the first direction; the second clamping arm 2 has a second through hole 23 recessed at the end opposite to the hinged end of the first clamping arm 1, and the locking member 3 slides in the second through hole 23 along the second direction, the second direction having an angle with the first direction, so that the locking member 3 can adjust the clamping force between the first clamping arm 1 and the second clamping arm 2 when sliding, and the second through hole 23 has a plurality of protrusions 2321 distributed along the second direction for engaging with the locking member 3.
[0077] Combination Figures 7 to 13 The following is a detailed explanation of the usage process of the aforementioned clamps:
[0078] In the initial state, such as Figure 7 As shown, one end of the first clamping arm 1 is hinged to one end of the second clamping arm 2, and the other end is in an open state; Figure 8 and Figure 9 As shown, after placing the flexible tube 5 between the first clamping section 12 and the second clamping section 22, the first clamping arm 1 is rotated clockwise, causing the locking member 3 in the first through hole 13 to extend into the second through hole 23; then the locking member 3 in the first through hole 13 is slid, and at the same time, the locking member 3 slides relative to the second through hole 23 in the second direction, as shown. Figure 10 As shown, as the locking member 3 slides, the clamping force between the first clamping arm 1 and the second clamping arm 2 increases until it reaches the specified value. Figures 11 to 13 As shown, when the locking member 3 is moved to the end of the second through hole 23, the locking member 3 engages with the protrusion 2321 at that position to lock the position of the first clamping arm 1 relative to the second clamping arm 2, and the first clamping section 12 and the second clamping section 22 clamp the flexible tube 5.
[0079] Compared with the ratchet clamps in the prior art, the pipe clamps provided in the above embodiments do not have the tendency to release inappropriately or undesirably, and the locking is more reliable. At the same time, there is no need to add tie straps or bolts or other connecting parts for locking or auxiliary locking, which facilitates locking installation and disassembly, is simple to operate, and saves time and costs.
[0080] In the above embodiments, such as Figures 8 to 12 As shown, when adjusting the clamping force between the first clamping arm 1 and the second clamping arm 2, if the locking member 3 moves away from the strip clamping channel 4 in the second direction relative to the second through hole 23, the clamping force between the first clamping arm 1 and the second clamping arm 2 can be gradually increased, thereby adjusting the fluid flow rate in the flexible tube 5.
[0081] Based on the above embodiments, when the fastening surfaces of the first clamping arm 1 and the second clamping arm 2 are parallel to the horizontal plane, the first direction can extend obliquely upward along the direction that gradually moves away from the strip clamping channel 4, and the second direction can extend horizontally or obliquely downward.
[0082] Of course, in some other embodiments, when adjusting the clamping force between the first clamping arm 1 and the second clamping arm 2, such as when the locking member 3 moves away from the strip clamping channel 4 in the second direction relative to the second through hole 23, the clamping force between the first clamping arm 1 and the second clamping arm 2 can also be gradually reduced.
[0083] In some embodiments, such as Figure 14 and Figure 15 As shown, in order to facilitate the disassembly and assembly of the locking member 3, the first through hole 13 includes a disassembly and assembly hole 131 and a sliding hole 132. The disassembly and assembly hole 131 is used for the locking member 3 to extend into and out of the first through hole 13, so as to realize the locking member 3 being installed in the first through hole 13 or the locking member being removed from the first through hole 13. The sliding hole 132 extends along the first direction and is used to slide with the locking member 3.
[0084] In practical use, the locking member 3 can be passed through the disassembly hole 131, and then the locking member 3 can be moved to the sliding hole 132 to achieve a sliding fit between the locking member 3 and the first through hole 13. When it is necessary to remove the locking member 3, simply move the locking member 3 to the disassembly hole 131 and remove it.
[0085] It should be noted that the function of the mounting hole 131 in allowing the locking member 3 to extend and retract can be achieved by making the opening size of the mounting hole 131 larger than the outer circumferential surface size of the locking member 3.
[0086] For example, the locking element 3 is a rotating body. The mounting hole 131 can be circular, and the diameter of the mounting hole 131 is greater than the maximum diameter of the locking element 3; the mounting hole 131 can also be square, and the side length of the mounting hole 131 is greater than the maximum diameter of the locking element 3; of course, the mounting hole 131 can also be elliptical, regular pentagonal or other irregular shapes.
[0087] The sliding hole 132 is used to slide with the locking member 3. The locking member 3 can limit its position relative to the sliding hole 132 by the limiting end face provided on its own axis.
[0088] Based on the different mating structures of the locking member 3, the first clamping arm 1, and the second clamping arm 2, the following two embodiments can be distinguished:
[0089] Example 1
[0090] In this first embodiment, as Figure 14 and Figure 15 As shown, the first clamping arm 1 also includes a first adjusting section. The first adjusting section includes two third sidewalls 14 connected to one end of the first clamping section 12 and spaced apart from each other. Each of the two third sidewalls 14 has a first through hole 13. The locking member 3 is slidably engaged with the two first through holes 13.
[0091] When the locking member 3 enters the second through hole 23, the portion of the second clamping arm 2 that forms the second through hole 23 extends between the two third side walls 14.
[0092] Specifically, such as Figure 14 As shown, the first adjustment section also includes a top wall 15 connected between the two third side walls 14, and the top wall 15 and the two third side walls 14 form a U-shaped structure.
[0093] In this first embodiment, as Figure 16 and Figure 17 As shown, the locking member 3 includes a first stepped post, which comprises a first post 31, a second post 32, and a third post 33 connected in sequence, wherein:
[0094] The first column 31 is used to slide with a first through hole 13 on a third sidewall 14, specifically to slide with a sliding hole 132 in the first through hole 13.
[0095] The third column 33 is used to slide with the first through hole 13 on another third sidewall 14, specifically to slide with the sliding hole 132 in the first through hole 13.
[0096] The second column 32 is used to slide with the second through hole 23. The end of the second column 32 facing the first column 31 has a first limiting end face 321, and the end of the second column 32 facing the third column 33 has a second limiting end face 322. The first limiting end face 321 and the second limiting end face 322 are sandwiched between the two third side walls 14 to limit the position of the locking member 3 relative to the two third side walls 14 along its own axial direction.
[0097] The above-mentioned arrangement facilitates the installation of the locking member 3, and at the same time ensures that the locking member 3 will not fall off the first clamping arm 1 when sliding relative to the second through hole 23 and when in the locked state.
[0098] The first column 31, the second column 32 and the third column 33 mentioned above can be cylinders, elliptical cylinders, prisms, etc.
[0099] Preferably, the first column 31, the second column 32 and the third column 33 are cylinders, the diameter of the second column 32 is larger than the diameter of the first column 31 and the third column 33, and the diameters of the first column 31 and the third column 33 can be equal.
[0100] In addition, the distance between the first limiting end face 321 and the second limiting end face 322 is preferably equal to the distance between the two third side walls 14, so as to avoid the sliding locking member 3 or the locking member in the locked state from shaking along its own axis.
[0101] In some embodiments, such as Figure 17As shown, the locking member 3 also includes a first pushing member 34. The first pushing member 34 is connected to the end of the first column 31 that is away from the second column 32. The end face of the first pushing member 34 that is away from the first column 31 is recessed. The recessed area can provide space for the fingers when the user pushes and pulls the locking member 3 to adjust the tightness of the clamp.
[0102] In addition, the outer peripheral surface of the first pushing member 34 may be provided with a concave-convex structure to increase the friction between the finger and the locking member when the finger holds the locking member 3.
[0103] In this first embodiment, as Figure 18 As shown, the second clamping arm 2 includes a first mating section with a T-shaped cross-section, and a second through hole 23 is recessed on the first mating section. When the locking member 3 enters the second through hole 23, the first mating section extends between the two third sidewalls 14.
[0104] In this first embodiment, as Figure 18 As shown, the second through hole 23 includes an inlet / outlet hole 231 and an extension hole 232 that is angled to the inlet / outlet hole 231. The inlet / outlet hole 231 is recessed into the second clamping arm 2, allowing the second column 32 of the locking member 3 to smoothly enter the second through hole 23. The extension hole 232 extends along the second direction and slides with the second column 32. The extension hole 232 is provided with a plurality of protrusions 2321 for limiting the position of the second column 32.
[0105] The second through hole 23 is L-shaped, which facilitates the locking member 3 to enter and exit the second through hole 23, making the operation more convenient. In the locked state, the extension hole 232 can prevent the locking member 3 from popping up, so that the locking member 3 can be stably engaged with the protrusion 2321 in the extension hole 232, and firmly lock the position of the first clamping arm 1 relative to the second clamping arm 2.
[0106] The number of the aforementioned protrusions 2321 can be two, three, four, etc.
[0107] like Figure 18 As shown, there are three protrusions 2321, and the three protrusions 2321 are arranged at equal intervals.
[0108] To facilitate the locking member 3 in the first through hole 13 to enter the second through hole 23, when the first clamping arm 1 and the second clamping arm 2 are just engaged, one end of the first through hole 13 is aligned with the inlet / outlet hole 231 of the second through hole 23, so that the locking member 3 located at that end can directly enter the second through hole 23.
[0109] Example 2
[0110] In this second embodiment, as Figure 19 and Figure 20As shown, the first clamping arm 1 also includes a second adjusting section. The second adjusting section includes a fourth side wall 16 connected to one end of the first clamping section 12. A first through hole 13 is provided on the fourth side wall 16, and the locking member 3 is slidably engaged with the first through hole 13.
[0111] When the locking member 3 enters the second through hole 23, as Figure 21 and Figure 22 As shown, the portion of the second clamping arm 2 that forms the second through hole 23 is located on one side of the fourth sidewall 16.
[0112] In this second embodiment, as Figure 23 and Figure 24 As shown, the locking member 3 includes a second pushing member 35 and a second stepped post, the second stepped post including a fourth post 36 and a fifth post 37, wherein:
[0113] The two ends of the fourth column 36 are connected to the second pusher 35 and the fifth column 37 respectively. The fourth column 36 is used to slide with the first through hole 13 on the fourth side wall 16, specifically to slide with the sliding hole 132 in the first through hole 13.
[0114] The fifth column 37 is used for sliding engagement with the second through hole 23;
[0115] The fifth column 37 has a third limiting end face 371 at the end facing the fourth column 36, the second pusher 35 has a fourth limiting end face 351 at the end facing the fourth column 36, and the fourth side wall 16 is sandwiched between the third limiting end face 371 and the fourth limiting end face 351 to limit the position of the locking member 3 relative to the fourth side wall 16 along its own axial direction.
[0116] The above-mentioned arrangement facilitates the installation of the locking member 3, and at the same time ensures that the locking member 3 will not fall off the first clamping arm 1 when sliding relative to the second through hole 23 and when in the locked state.
[0117] The aforementioned fourth prism 36 and fifth prism 37 can be cylinders, elliptical cylinders, prisms, etc.
[0118] Preferably, the fourth column 36 and the fifth column 37 are cylinders, and the diameter of the fifth column 37 is larger than the diameter of the fourth column 36.
[0119] In addition, the distance between the third limiting end face 371 and the fourth limiting end face 351 is preferably equal to the thickness of the fourth side wall 16, so as to prevent the sliding locking member 3 or the locking member from shaking along its own axis when it is in the locked state.
[0120] Similar to Embodiment 1, the end face of the second pushing member 35 facing away from the fourth column 36 is recessed, and the outer peripheral surface of the second pushing member 35 may be provided with a concave-convex structure.
[0121] In this second embodiment, as Figure 25 and Figure 26 As shown, the second clamping arm 2 includes a second mating section with a T-shaped cross-section, and a second through hole 23 is recessed on the second mating section. When the locking member 3 enters the second through hole 23, the second mating section is located on one side of the fourth side wall 16.
[0122] In this second embodiment, similar to the first embodiment, as follows: Figure 25 As shown, the second through hole 23 includes an inlet / outlet hole 231 and an extension hole 232 that communicates with the inlet / outlet hole 231 at an angle. The inlet / outlet hole 231 is recessed into the second clamping arm 2, allowing the second post 32 of the locking member 3 to smoothly enter the second through hole 23. The extension hole 232 extends along the second direction and slides with the fifth post 37. The extension hole 232 has multiple protrusions 2321 inside. To save space, the technical effects of the second through hole 23 will not be described in detail here.
[0123] The aforementioned tube clamp can be used in various situations that enable the flexible tube 5 to be switched on and off and to adjust the flow rate of the flexible tube 5. It is commonly used in the medical or pharmaceutical fields and can selectively control the flow of fluid from or to the patient.
[0124] A second aspect of the present invention provides a conveying pipeline, which includes the aforementioned pipe clamp.
[0125] The delivery pipeline provided by the second aspect of the present invention has the pipe clamp provided by the embodiment of the first aspect of the present invention, thereby having all the beneficial effects of the pipe clamp provided by the embodiment of the first aspect of the present invention.
[0126] In some embodiments, the above-mentioned delivery pipeline includes a flexible pipe 5, which is clamped by the above-mentioned pipe clamp to realize the flow and disconnection of fluid.
[0127] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
