Description

Technical Field

[0001] This invention relates to the field of prefabricated modular data center technology, and in particular to a prefabricated modular liquid-cooled container data center stacking structure that can be quickly positioned and locked. Background Technology

[0002] With the explosive growth of large-scale AI model training and inference, the power density of a single data center rack has rapidly increased from the traditional 5-10kW to 50-120kW. Air cooling technology can no longer meet the heat dissipation requirements of high-density computing power, and liquid cooling has become the industry's recognized mainstream technology. Against this backdrop, prefabricated modular liquid-cooled container data centers, with their "factory prefabrication and on-site assembly" construction model, have reduced the traditional data center construction cycle of 12-18 months to 3-6 months, while achieving energy savings of as low as 1.05-1.15, making them the preferred solution for current AI computing infrastructure construction.

[0003] To further improve land use efficiency and reduce the construction cost per unit of computing power, multi-layer stacking of prefabricated modular liquid-cooled cabins has become an inevitable trend in the industry. In first-tier cities and surrounding areas, land resources are scarce and expensive. By deploying 3-5 layers of stacked cabins, the computing power density per unit area can be increased by 3-5 times, significantly reducing land and civil engineering costs. At the same time, multi-layer stacking can also shorten the length of liquid-cooled pipes, power cables, and network cables, reducing transmission losses and construction costs, and achieving better system energy efficiency.

[0004] Currently, the stacking connection technology for prefabricated modular liquid-cooled containers mainly originates from the container shipping industry, with the two mainstream methods being twist-lock connections and all-bolted flange connections. Twist-lock connections achieve locking through rotating locks between the upper and lower compartment corner fittings, offering a relatively fast connection speed and suitable for short-term turnover transportation of standard-sized containers. However, they have inherent drawbacks: the single-point pin is prone to wear and deformation due to concentrated stress; it is sensitive to corner deformation and installation errors, easily leading to false locking that is difficult to diagnose; internal springs and rotating parts are prone to corrosion and jamming, and are easily loosened by vibration; and horizontal positioning relying solely on gaps can easily cause slippage and impact. This connection method is particularly unsuitable for the long-term static stacking of large-size, heavy-weight liquid-cooled containers.

[0005] All-bolted flange connections achieve rigid connections through multiple high-strength bolts on the mating flanges. The connection has good rigidity and high reliability, but the construction efficiency is extremely low: a standard 40-foot container requires the installation of 16-32 high-strength bolts, which is time-consuming and labor-intensive.

[0006] Regarding the stacking and positioning technology of prefabricated liquid-cooled container cabins, the existing solution mainly uses a conical positioning shaft fixed to the bottom of the container and a positioning hole on the top of the lower container to achieve positioning. This method has obvious shortcomings: low positioning accuracy, limited guiding range of the conical positioning shaft, and the allowable initial alignment error is usually no more than ±10mm. It requires the crane operator to repeatedly adjust the position at high altitude, the success rate of lifting on the first attempt is less than 60%, and it often requires a second lifting for fine-tuning, which seriously affects construction efficiency.

[0007] In summary, existing prefabricated modular liquid-cooled container stacking technology suffers from technical problems such as low positioning efficiency, poor accuracy, the need for repeated debugging, and either unreliable or inefficient locking methods, which restrict the widespread application of multi-layer stacking technology. Summary of the Invention

[0008] To address the aforementioned technical problems, this invention provides a prefabricated modular liquid-cooled container data center stacking structure that can achieve rapid and accurate positioning, improve positioning success rate, and simultaneously ensure connection reliability and construction efficiency.

[0009] The present invention relates to a prefabricated modular liquid-cooled container data center stacking structure with rapid positioning and locking capability, comprising a container housing, wherein all equipment of the container data center is installed within the container housing, and mounting frames are provided at the top and bottom of the container housing, and lockable doors are installed on its sides, and further comprising:

[0010] The fixed columns are configured as four, and the fixed columns are tubular. One fixed column is vertically installed on each side of the long outer wall of the container. The top and bottom of the fixed column are coaxially provided with connecting pipes. The lower connecting pipe can be detachably installed with a guide shaft.

[0011] A cone assembly is installed on the top of a corresponding fixed column via a detachable mechanism, and the guide hole at the bottom of the cone assembly is coaxially connected to the connecting pipe at the top of the fixed column. The cone assembly is installed on at least two diagonally opposite fixed columns, and the cone assembly and the guide shaft cooperate for the lateral positioning of the container body.

[0012] The top of the upper mounting frame is evenly distributed with several pins, and the bottom of the lower mounting frame is evenly distributed with several pin holes. The number and position of the pin holes are adapted to the number and position of the pins.

[0013] The L-shaped channel steel clamp has docking components at the bottom of the container and at the four corners of the bottom mounting frame. When two container boxes are stacked, the L-shaped channel steel clamp will lock the two corresponding docking components, and the L-shaped channel steel clamp is equipped with a locking component.

[0014] Furthermore, the conical assembly is formed by joining two semi-conical cylinders with bases. Fixing blocks are installed on the opposite sides of the two bases. Several fixing shafts are provided at the bottom of each fixing block. Support blocks are provided at the top of the two opposite side walls of the fixing column. The positions of the two support blocks are adapted to the positions of the two fixing blocks respectively. Several fixing holes are provided through the top of each support block. Several fixing shafts of the fixing blocks are slidably inserted into several fixing holes of the corresponding side support blocks. A reinforcing component is provided at the top of the conical assembly.

[0015] Furthermore, the docking assembly includes two docking strips, which are respectively installed on the adjacent side walls of the corresponding mounting frame corners, and both docking strips are horizontally arranged. The top or bottom end of the U-shaped groove of the L-shaped channel steel clamp is set as an inclined surface that expands from the inside out.

[0016] Furthermore, the locking assembly includes a locking bolt, and locking blocks are installed at the corners of the upper mounting frame. The locking blocks have threaded grooves on the face of the L-shaped channel steel clip. The L-shaped channel steel clip has a through hole that is coaxial with the threaded groove and is sized to fit the threaded groove. When the L-shaped channel steel clip is installed in the container body, a washer is fitted on the locking bolt, which then passes through the through hole and is threadedly connected and locked with the threaded groove.

[0017] Furthermore, a limiting ring is provided in the middle of the guide shaft, the upper side of the guide shaft is threaded, the lower side of the connecting pipe is threaded, and the guide shaft is threaded to the lower side of the connecting pipe.

[0018] Furthermore, the reinforcing component includes two reinforcing pins. Each semi-conical cylinder has a semi-cylindrical ring at its top. One semi-cylindrical ring has arc-shaped rods installed on opposite sides of its outer side wall, and the other semi-cylindrical ring has pin seats with reinforcing holes installed on opposite sides of its outer side wall. The two reinforcing pins are respectively installed at the bottom ends of the two arc-shaped rods. After the two semi-cylindrical rings are joined together, the two arc-shaped rods can slide longitudinally to hold the semi-cylindrical ring with the pin seats installed, while the two reinforcing pins slide into the two reinforcing holes respectively.

[0019] Furthermore, each of the aforementioned docking strips is provided with a limit strip in parallel, and a gap is provided between the limit strip and the docking strip. After the L-shaped channel steel clip is attached to the docking strip, the limit strip slides and fits tightly against the outer side wall of the corresponding side of the L-shaped channel steel clip.

[0020] Furthermore, the bottom end of the guide shaft and the top end of each pin are both conical or dome-shaped.

[0021] Furthermore, the fixing column is fixed to the side wall of the container body by an extension member, which is connected to the upper and lower frame beams of the container body. The extension member is used to extend the cone assembly to the side of the container body.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] The coarse positioning structure, which uses a large-opening conical cylinder assembly in conjunction with a guide shaft, greatly expands the initial alignment allowable error. The crane operator does not need to make repeated fine adjustments at high altitudes, which greatly improves the success rate of lifting in one go. It solves the problem of the small guiding range of traditional conical positioning shafts and the need for secondary lifting, and significantly shortens the lifting operation time.

[0024] The three-level positioning system, consisting of coarse positioning of the cone assembly and guide shaft, precise positioning of the connecting pipe and guide shaft, and final alignment of the pin and pin hole, greatly improves the installation accuracy of the upper and lower compartments in both horizontal and vertical directions, providing a reliable guarantee for the rapid docking and installation of subsequent liquid cooling pipes and power cables.

[0025] The quick-locking method using L-shaped channel steel clamps and docking components replaces the traditional all-bolt flange connection, greatly improving installation efficiency. At the same time, this connection method generates uniform pre-tightening force through inclined extrusion, achieving surface contact force distribution, avoiding the defects of single-point concentrated force, easy wear, and easy loosening of torsion lock connection. The connection has good rigidity and high reliability, and is suitable for long-term static stacking of large-size and heavy liquid-cooled containers.

[0026] The cone assembly features a detachable design, allowing for flexible selection of the installation quantity based on the weight and volume of the container, making it suitable for prefabricated modular liquid-cooled containers of different specifications. All connecting components can be designed with standardized specifications, facilitating mass production in the factory and on-site replacement and maintenance. Attached Figure Description

[0035] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0036] like Figures 1 to 7 As shown:

[0037] Example 1:

[0038] The present invention relates to a prefabricated modular liquid-cooled container data center stacking structure with rapid positioning and locking capability, comprising a container housing 1, wherein all equipment of the container data center is installed inside the container housing 1, and mounting frames 2 are provided at the top and bottom of the container housing 1, and lockable opening and closing doors 3 are installed on its sides, and further comprising:

[0039] Fixed column 4, four fixed columns 4 are provided, and the fixed columns 4 are tubular. One fixed column 4 is vertically installed on both sides of the long side outer wall of the container 1. The top and bottom of the fixed column 4 are coaxially provided with connecting pipes 5. The lower connecting pipe 5 can be detachably installed with a guide shaft 6.

[0040] A cone assembly is installed on the top of the corresponding fixed column 4 via a detachable mechanism, and the guide hole at the bottom of the cone assembly is coaxially connected to the connecting pipe 5 at the top of the fixed column 4. The cone assembly is installed on at least two diagonally opposite fixed columns 4. The cone assembly and the guide shaft 6 cooperate for the lateral positioning of the container body 1.

[0041] The top of the upper mounting frame 2 is evenly distributed with several pins 7, and the bottom of the lower mounting frame 2 is evenly distributed with several pin holes 8. The number and position of the pin holes 8 are adapted to the number and position of the pins 7.

[0042] L-shaped channel steel clamp 9, the bottom of the container body 1 and the four corners of the bottom mounting frame 2 are all provided with docking components. When the two container bodies 1 are stacked, the L-shaped channel steel clamp 9 will lock the corresponding two docking components, and the L-shaped channel steel clamp 9 is provided with locking components.

[0043] Preferably, the locking assembly includes a locking bolt 17, and locking blocks 18 are installed at the corners of the upper mounting frame 2. The locking blocks 18 have threaded grooves on the face of the L-shaped channel steel clip 9. The L-shaped channel steel clip 9 has a through hole that is coaxial with the threaded groove and is sized to fit the threaded groove. When the L-shaped channel steel clip 9 is installed in the container body 1, a washer 19 is fitted on the locking bolt 17, and then the bolt passes through the through hole and is threadedly connected and locked with the threaded groove.

[0044] Preferably, a limiting ring 20 is provided in the middle of the guide shaft 6, the upper side of the guide shaft 6 is provided with a thread, the lower side of the connecting pipe 5 is provided with an internal thread, and the guide shaft 6 is threadedly connected to the lower side of the connecting pipe 5.

[0045] More preferably, the fixing column 4 is fixed to the side wall of the container 1 by an extension member 26, the extension member 26 is connected to the upper and lower frame beams of the container, and the extension member 26 is used to extend the cone assembly to the side of the container 1.

[0046] In this embodiment,

[0047] First, the horizontal leveling and fixing of the bottom container 1 is completed on the ground, and the verticality of all fixing columns 4 and the coaxiality of connecting pipes 5 are checked.

[0048] Based on the weight and volume of the container 1 to be stacked, determine the number of cone assemblies to be installed: for example, for a standard 40-foot liquid-cooled container, installing two cone assemblies diagonally is sufficient to meet the positioning requirements; for containers with a larger volume and a weight exceeding 30 tons, three to four cone assemblies can be selected to improve positioning stability. Install the selected number of cone assemblies at the top of the corresponding fixing column 4 of the bottom container using a detachable mechanism, ensuring that the guide hole at the bottom of the cone assembly is coaxially connected to the connecting pipe 5 at the top of the fixing column 4.

[0049] On the lower connecting pipe 5 of the fixing column 4 of the upper-level container 1, thread the same number of guide shafts 6 as the cone assembly, and tighten them until the limit ring 20 is tightly fitted with the end face of the connecting pipe 5, ensuring that the guide shafts 6 are firmly installed and their verticality meets the requirements. Check that all the pin holes 8 at the bottom of the upper-level container mounting frame 2 are unobstructed and free of debris.

[0050] Using a crane, the upper-level container 1 is slowly lifted to a certain height, such as 2 meters, directly above the lower-level container. The crane operator only needs to roughly align the guide shaft 6 of the upper-level container with the large opening of the corresponding cone component of the lower-level container, without the need for precise alignment.

[0051] The upper-level container is slowly lowered. Once the bottom end of the guide shaft 6 enters the large opening of the cone assembly, the upper-level container will automatically correct its horizontal position under the guidance of the cone's inclined surface 16. Even if there is a large initial alignment error, it can be gradually guided to the correct position. This process requires no manual intervention, significantly reducing the operational difficulty for the crane operator.

[0052] Once the guide shaft 6 has fully slid into the connecting pipe 5 at the top of the fixed column 4, the upper and lower cabins have been precisely positioned, with the horizontal error controlled within ±2mm. Because the cone assembly is detachable, workers can remove it from the top of the fixed column 4 for reuse. Continuing to slowly lower the upper cabin, under the continuous guidance of the connecting pipe 5 and the guide shaft 6, the pin hole 8 at the bottom of the upper cabin mounting frame 2 will precisely insert into the pin shaft 7 at the top of the lower cabin mounting frame 2, completing the final vertical positioning.

[0053] After the upper and lower compartments are fully fitted together, the docking strip 15 of the upper compartment is aligned with the docking strip 15 of the lower compartment. L-shaped channel steel clips 9 are inserted into the docking components at the four corners, so that the U-shaped grooves of the L-shaped channel steel clips 9 simultaneously hold the two aligned docking strips 15 inside. After fitting the washer 19 onto the locking bolt 17, it passes through the through hole on the L-shaped channel steel clip 9 and threadedly connects to the threaded groove of the locking block 18 at the corner of the upper mounting frame 2 and is tightened.

[0054] During the tightening of the locking bolt 17, the inclined surface 16 in the U-shaped groove of the L-shaped channel steel clamp 9 will be displaced as the bolt is tightened, gradually squeezing the upper and lower connecting strips 15, making the mounting frames 2 of the two boxes more tightly squeezed, providing sufficient preload force to ensure that there is no relative displacement between the upper and lower compartments. According to actual needs, reinforcing ribs can be set on the L-shaped channel steel clamp 9.

[0055] The entire locking process is simple to operate and only requires 4 bolts to complete the locking process. Only 1-2 workers are needed to complete the entire locking operation of a standard container within 5-8 minutes.

[0056] The technical solution obtained through Embodiment 1 achieves basic rapid positioning and locking functions. The cooperation between the cone assembly and the guide shaft 6 greatly improves the hoisting positioning efficiency. The combination of L-shaped channel steel clamp 9 and locking bolt 17 utilizes the pressure of the inclined plane 16 to generate uniform pre-tightening force, which significantly improves the construction speed while ensuring connection reliability.

[0057] In the technical solution of the present invention, the guide shaft 6 is preferably made of No. 45 steel and subjected to quenching and tempering followed by high-frequency surface hardening, and the pin shaft 7 is preferably made of No. 45 steel and subjected to normalizing and surface hardening. The above preferred solutions have both high strength, high wear resistance and impact resistance.

[0058] Example 2:

[0059] As a preferred embodiment, the conical assembly is formed by joining two semi-conical cylinders 10 with bases 11. Fixing blocks 12 are installed on the opposite sides of the two bases 11. Each fixing block 12 has several fixing shafts 13 at its bottom end. Support blocks 14 are provided on the top of the two opposite side walls of the fixing column 4. The positions of the two support blocks 14 are adapted to the positions of the two fixing blocks 12. Several fixing holes are provided through the top of each support block 14. Several fixing shafts 13 of the fixing blocks 12 are slidably inserted into the several fixing holes of the corresponding side support blocks 14. A reinforcing component is provided on the top of the conical assembly.

[0060] Preferably, the reinforcing assembly includes two reinforcing pins 21. Each semi-conical cylinder 10 has a semi-cylindrical ring 22 at its top. One semi-cylindrical ring 22 has arc-shaped rods 23 installed on opposite sides of its outer side wall. The other semi-cylindrical ring 22 has pin seats 24 with reinforcing holes installed on opposite sides of its outer side wall. The two reinforcing pins 21 are respectively installed at the bottom ends of the two arc-shaped rods 23. After the two semi-cylindrical rings 22 are joined together, the two arc-shaped rods 23 can slide longitudinally to hold the semi-cylindrical ring 22 with the pin seats 24 installed. At the same time, the two reinforcing pins 21 slide into the two reinforcing holes respectively.

[0061] More preferably, the bottom end of the guide shaft 6 and the top end of each pin 7 are both set as conical or dome-shaped.

[0062] In this embodiment,

[0063] Based on Embodiment 1, this embodiment proposes a preferred structure for the conical cylinder assembly, and the specific implementation process is as follows:

[0064] Before using the two semi-conical cylinders 10, the two semi-conical cylinders 10 are first misaligned and connected, and then slid longitudinally. The two arc-shaped rods 23 on one of the semi-cylindrical rings 22 are slid downwards so that they hold the other semi-cylindrical ring 22. At the same time, the two reinforcing pins 21 at the bottom of the arc-shaped rods 23 will automatically slide into the reinforcing holes of the corresponding pin seats 24 to complete the reinforcement of the top of the cone assembly.

[0065] After two semi-conical cylinders 10 with bases 11 are joined together, the inner walls of the two semi-conical cylinders 10 form a complete conical guide surface. This allows the fixing shafts 13 at the bottom of the fixing blocks 12 on the bases 11 of the two semi-conical cylinders 10 to align with the fixing holes on the support blocks 14 on both sides of the fixing post 4, and insert vertically downwards, completing the installation of the conical cylinder assembly at the top of the fixing post 4. This plug-in installation method requires no tools and the installation time is no more than 30 seconds per unit.

[0066] Similar to Embodiment 1, during the hoisting of the upper-level container, the conical structure at the bottom of the guide shaft 6 can more smoothly enter the large opening of the cone assembly, further reducing the difficulty of initial alignment. As the guide shaft 6 slides down the inner wall of the cone, the two semi-conical cylinders 10, through the cooperation of the fixed shaft 13 and the support block 14, can evenly bear the lateral force applied by the guide shaft 6, avoiding the problem of deformation caused by uneven force in traditional integral cones. At the same time, the reinforcement structure can effectively prevent the two semi-conical cylinders 10 from separating due to lateral force during the guiding process, ensuring the stability and safety of the guiding process.

[0067] After the guide shaft 6 is fully inserted into the connecting tube 5, slide the arc-shaped rod 23 upward to dislodge the reinforcing pin 21 from the reinforcing hole. Then, lift the two half-cone cylinders 10 upward respectively to easily remove the cone assembly from the top of the fixing post 4. The disassembled cone assembly can be separated into two independent half-cone cylinders 10, which is convenient for transportation and storage, and occupies only half the space of the integral cone cylinder.

[0068] The modular conical assembly design makes installation and disassembly more convenient and can be completed quickly without tools; the reinforced components effectively improve the structural strength and stability of the conical assembly, enabling it to withstand greater lateral impact forces; the modular structure facilitates transportation and storage, reducing logistics costs.

[0069] In the technical solution of the present invention, the main body of the split cone assembly is preferably made of Q355 high-strength steel plate, and the matching fixed shaft 13 and reinforcing pin 21 are made of 45 steel with heat treatment. The overall structure has sufficient rigidity and is not easy to deform. All components are selected with consideration of hardness, positioning accuracy and construction economy. It is suitable for stacking of container units of different weights, has a long service life and high overall cost performance.

[0070] Example 3:

[0071] As a preferred embodiment, the docking assembly includes two docking strips 15, which are respectively installed on the adjacent side walls of the corner of the corresponding mounting frame 2, and both docking strips 15 are horizontally arranged. The top or bottom of the U-shaped groove of the L-shaped channel steel clamp 9 is set as an inclined surface 16 that expands from the inside to the outside.

[0072] Preferably, each of the connecting strips 15 is provided with a limit strip 25 in parallel, and there is a gap between the limit strip 25 and the connecting strip 15. After the L-shaped channel steel clip 9 is clipped onto the connecting strip 15, the limit strip 25 slides tightly against the outer side wall of the corresponding side of the L-shaped channel steel clip 9.

[0073] In this embodiment,

[0074] Based on Embodiment 1, this embodiment proposes a preferred docking assembly and L-shaped channel steel clamp 9, and the specific implementation process is as follows:

[0075] After the upper and lower compartments are fully fitted, align the U-shaped groove of the L-shaped channel steel clip 9 with the upper and lower mating strips 15.

[0076] When the L-shaped channel steel clamp 9 slides inward along the connecting strip 15, the limiting strip 25, which is parallel to the outside of the connecting strip 15, slides tightly against the outer wall of the L-shaped channel steel clamp 9, thus limiting the L-shaped channel steel clamp 9. Under the combined clamping of the limiting strip 25 and the corresponding connecting strip 15, the tensile strength of the L-shaped channel steel is greatly improved, and the clamping reliability and safety of the L-shaped channel steel are improved.

[0077] Once the L-shaped channel steel clip 9 is fully engaged, its through hole will automatically align with the threaded groove on the locking block 18. At this point, simply pass the locking bolt 17 through the through hole and tighten it. During the tightening process of the locking bolt 17, the inclined surface 16 within the U-shaped groove of the L-shaped channel steel clip 9 will undergo axial displacement, applying uniform compressive force to the upper and lower mating strips 15, ensuring a tight fit between the upper and lower mounting frames 2 and generating sufficient preload. The mating strips 15 also prevent the L-shaped channel steel clip 9 from rotating during the tightening process of the locking bolt 17, ensuring that the locking force is evenly transmitted to the upper and lower mating strips 15 and avoiding uneven local stress.

[0078] Through the technical solution of Embodiment 3, the setting of the limiting strip 25 improves the accuracy and stability of the installation of the L-shaped channel steel clamp 9, the docking strip 15 prevents the clamp from rotating during the locking process, and the inclined surface 16 in the U-shaped groove of the L-shaped channel steel clamp 9 can uniformly squeeze the docking strip 15, further improving the reliability of the connection and the uniformity of the pre-tightening force.

[0079] The working principle of this invention is as follows:

[0080] This invention achieves rapid stacking of prefabricated modular liquid-cooled cabins through a three-level system of "coarse positioning - fine positioning - final locking".

[0081] First, the large-opening cone assembly and the guide shaft 6 are used to achieve a large range of coarse horizontal positioning, which greatly reduces the difficulty of hoisting and alignment. Then, the connecting pipe 5 and the guide shaft 6 are precisely matched to control the horizontal error within a very small range and complete the precise positioning. At the same time, the guide shaft 6 and the connecting pipe 5 can also play a role in horizontal reinforcement. Finally, the pin 7 and the pin hole 8 are inserted to achieve the final horizontal positioning.

[0082] After positioning, L-shaped channel steel clamps 9 are used to simultaneously clamp the docking components at the corners of the upper and lower compartments. By tightening the locking bolts 17, the inclined surface 16 in the U-shaped groove of the L-shaped channel steel clamps 9 is used to squeeze the docking strip 15, generating a uniform pre-tightening force, so that the mounting frames 2 of the upper and lower compartments fit tightly together, achieving a fast and reliable connection.

[0083] Meanwhile, by extending the cone assembly to the side of the container using the extension 26, workers can install and disassemble the cone assembly from the outside of the container body 1, which significantly improves construction safety.

[0084] The entire process requires no complex tools or a large amount of manpower, effectively solving the problems of low positioning efficiency, poor accuracy, and difficulty in balancing the reliability of locking methods with construction efficiency in existing technologies. It is suitable for the rapid multi-layer stacking deployment of high-density AI computing infrastructure.

[0085] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
