Hereinafter, each embodiment of the invention disclosed in the present application will be described with reference to the drawings. However, the present invention can be embodied in various forms without departing from the gist thereof, and should not be construed as being limited to the description of the embodiments exemplified below.

In order to make the description clearer, the drawings may schematically show the width, thickness, shape, etc. of each part compared to the actual embodiment, but it is only an example and does not limit the interpretation of the present invention. In addition, in this specification and each drawing, elements having the same functions as those described with respect to the previous drawings may be denoted by the same reference numerals, and redundant description may be omitted.

In this specification and the drawings, the same reference numerals are used to collectively indicate a plurality of identical or similar configurations, and a hyphen and a number are added after the reference numerals to indicate them individually. When a plurality of parts of one configuration are separately described, the same reference numerals are used, and alphabetic characters are used.

In the present specification and claims, the term "a plurality of elements integrated" means that the plurality of elements have different functions but are formed from a single member and have a continuous configuration. The integrated elements therefore contain the same materials and have the same composition.

<First embodiment>
A pipe support device 100, which is one embodiment of the present invention, will be described below. The pipe support device 100 has the function of supporting the pipe and following the movement of the pipe due to changes in heat and weight. In the drawings used in the following description, for convenience, the vertical direction is the z-direction, and the horizontal plane perpendicular to the z-direction is the xy plane. The x and y directions are orthogonal to the z direction.

1. A perspective view of the overall structural pipe support device 100 is schematically shown in FIG. The piping support device 100 has a pair of hanger plates 102, a spring seat 106, at least one spring 108, a plurality of support frames 110, and a turnbuckle 116 as a basic configuration. These structures are formed using metals such as iron and stainless steel. These configurations will be described in detail below.

1-1. Hanger Plates A pair of hanger plates 102 including a first hanger plate 102-1 and a second hanger plate 102-2 are configured to suspend the piping support device 100 including spring seats 106, springs 108, support frames 110, turnbuckles 116, and the like. A pair of hanger plates 102 are fixed so that their main surfaces face each other in parallel with the z-direction. Although the hanger plates 102 may be fixed to each other by any method, for example, bolts 130 and nuts 132 may be used. Each of the pair of hanger plates 102 can be provided with an opening 102a for hanging the pipe support device 100 from a support or the like. The openings 102a are provided so as to overlap each other in the direction perpendicular to the z-direction (the y-direction in the example of FIG. 1). Although not shown, the pair of hanger plates 102 may be of one integrated construction.

1-2. Spring Seat The spring seat 106 is a plate-like member positioned below the hanger plate 102 and partly overlapped with the hanger plate 102, and is arranged such that its main surface is parallel or substantially parallel to the xy plane. As can be seen from the schematic top view of the spring seat 106 shown in FIG. 2, the spring seat 106 includes a central portion 106a overlapping the spring 108 indicated by broken lines and a pair of end portions 106b sandwiching the central portion 106a. The end portions 106b are portions that protrude from the center portion 106a in the xy plane and face each other through the center portion 106a. Therefore, end 106b does not overlap spring 108 in the z-direction. Although the details will be described later, the support frame 110 restricts the movement of the spring 108 in the xy plane. Therefore, it is not necessary to provide the lower surface of the spring seat 106 with a structure (unevenness, ribs, etc.) for preventing the movement of the spring 108, and the entire lower surface of the spring seat 106 may be flat. Hereinafter, the direction in which the end portion 106b extends from the center portion 106a is defined as the x direction.

1-3. Support Frame The pipe support device 100 is provided with two or more support frames 110 . Although the number of support frames 110 is not limited, the plurality of support frames 110 can have four support frames 110, as shown in FIG. 1, for example. The description will be continued below using an example in which the plurality of support frames 110 includes first to fourth support frames 110-1 to 110-4.

A plurality of support frames 110 are connected and fixed to one of the pair of hanger plates 102, respectively. In the example shown in FIG. 1, the first support frame 110-1 and the second support frame 110-2 are connected and fixed to the first hanger plate 102-1 and extend downward (i.e., in the z-direction) from the first hanger plate 102-1. The first support frame 110-1 and the second support frame 110-2 may be connected and fixed to the first hanger plate 102-1 by welding, bolting, or the like, or may be integrated with the first hanger plate 102-1. Similarly, a third support frame 110-3 and a fourth support frame 110-4 are also connected and fixed to the second hanger plate 102-2 and extend downward from the second hanger plate 102-2. The third support frame 110-3 and the fourth support frame 110-4 may also be connected and fixed to the second hanger plate 102-2 by welding, bolting, or the like, or may be integrated with the second hanger plate 102-2. The first support frame 110-1 and the third support frame 110-3, and the second support frame 110-2 and the fourth support frame 110-4 are fixed together using bolts 134 and nuts 136, for example.

A plurality of support frames 110 are arranged to surround a portion of spring seats 106 and springs 108 . More specifically, as shown in FIG. 2, the plurality of support frames 110 surrounds the springs 108 in the xy plane and also surrounds the central portion 106a of the spring seat 106. As shown in FIG. Further, the plurality of support frames 110 are arranged so as to sandwich the end portion 106b of the spring seat 106. As shown in FIG. In the example shown in FIG. 2, the first support frame 110-1 and the third support frame 110-3 face each other via one end 106b in the y direction. Similarly, the second support frame 110-2 and the fourth support frame 110-4 also face each other via the other end 106b in the y direction. Therefore, one end 106b in the y direction is sandwiched between the first support frame 110-1 and the third support frame 110-3, and the other end 106b is sandwiched between the second support frame 110-2 and the fourth support frame 110-4. Although FIG. 2 shows an example in which the end portion 106b is in contact with the support frame 110, the width (length in the y direction) of the end portion 106b may be shorter than the interval _d1 between the support frames 110 that hold it. In this case, the spring seat 106 can take a state of not contacting the support frame 110 .

Here, as shown in FIG. 2, the length of the central portion 106a in the y direction is longer than the width (length in the y direction) of the end portions 106b. In addition, the distance d1 between the two support frames 110 that sandwich the spring seat 106 in the y direction, that is, the two support frames 110 that sandwich one end portion 106b (for example, the first support frame 110-1 and the third support frame 110-3, or the second support frame 110-2 and the fourth support frame 110-4) is _equal to or greater than the width of the end portion 106b, but the length of the central portion 106a in the y direction. less than Therefore, the movement of the spring seat 106 in the xy plane is restricted by the support frame 110, and the spring seat 106 is allowed to slide in the z direction with the end portion 106b sandwiched between the pair of support frames 110. FIG.

Further, the support frames 110 are arranged such that the distance _d1 between the two support frames 110 that sandwich one end 106b is smaller than the outer diameter D of the spring 108. As shown in FIG. At the same time, the support frames 110 are arranged such that the distance _d2 between the two support frames 110 overlapping in the x-direction, that is, the two support frames 110 (for example, the first support frame 110-1 and the second support frame 110-2, or the third support frame 110-3 and the fourth support frame 110-4) extending in the z-direction is smaller than the outer diameter D of the spring 108. By adopting such an arrangement, the springs 108 cannot pass between the adjacent support frames 110, thereby preventing the springs 108 from falling off the pipe support device 100. FIG.

As shown in FIG. 1, the lower end of each support frame 110 is bent to have a hook shape. Specifically, as shown in FIGS. 3A and 3B, each support frame 110 includes a first portion 110a extending from the hanger plate 102 in the z-direction and surrounding the spring seats 106 and the springs 108, a third portion 110c positioned inside the springs 108 and surrounded by the springs 108, and a second portion positioned between the first and

third portions

110a and 110c and overlapping the springs 108 under the springs 108. Bend so as to have The second portion 110b supports the spring 108 and determines the position of the lower end of the spring 108. As shown in FIG. Although the details will be described later, the lower end of the spring 108 is hooked by such a hook shape, and the behavior of the spring 108 is stabilized.

1-4. The spring and turnbuckle spring 108 are arranged between the second portion 110b of the support frame 110 and the spring seat 106 so that their central axis (hereinafter referred to as the spring axis) is in the z-direction. Spring 108 is sandwiched between second portion 110b and spring seat 106, but need not be welded or bolted to them.

4 and 5 show schematic side views of the pipe support device 100. FIG. The turnbuckle 116 is arranged so that its longitudinal direction faces the z-direction, and its upper end is suspended from the spring seat 106 via a shaft 118 . The shaft 118 may be welded to the spring seat 106, or a bolt penetrating the spring seat 106 may be used as the shaft 118 as shown in FIGS.

A piping fixture 150 for fixing a piping 152 to the turnbuckle 116 is connected to the lower end of the turnbuckle 116 . The method of connecting the turnbuckle 116 and the pipe fixture 150 is arbitrary. For example, the turnbuckle 116 and the pipe fixture 150 may be connected by bolting using an opening 116a (see FIG. 1) provided at the lower end of the turnbuckle 116.

Normally, when connecting the pipe 152 , the pipe support device 100 is suspended from a post or the like using the opening 102 a , and the pipe 152 is attached to the turnbuckle 116 via the pipe fixture 150 in this state. At this time, if the length of the spring 108 is the natural length, the spring 108 contracts due to the weight of the pipe 152 and the pipe fixture 150, and accordingly the turnbuckle 116 and the pipe fixture 150 and pipe 152 attached thereto move downward. If such a movement occurs, the pipe 152 will be arranged in a state deviated downward from the predetermined position, so it is preferable to set (preset) the spring 108 in a compressed state in advance so that the turnbuckle 116 does not move in the z direction due to the restoring force of the spring 108 even when the pipe 152 and the pipe fixture 150 are connected.

Therefore, the pipe support device 100 may further include a pair of fixing plates 114 sandwiching the plurality of support frames 110 as a configuration for presetting the springs 108 (FIG. 6). There are no restrictions on the shape and structure of the fixing plate 114 , and the fixing plate 114 may be configured to have the function of fixing the distance between the spring seat 106 and the support frame 110 and/or the hanger plate 102 . For example, as shown in FIG. 6, the fixing plate 114 may be a plate-like

member having openings

114a and 114b through which at least one of the pair of hanger plates 102 and the end portion 106b of the spring seat 106 pass, respectively. In the example shown in FIG. 6, a pair of hanger plates 102 pass through openings 114a at the same time. Any length of spring 108 can be accommodated between second portion 110b of support frame 110 and spring seat 106 by appropriately adjusting the distance between

openings

114a and 114b. Therefore, using the fixing plate 114, the pipe 152 and the pipe fixture 150 are connected to the turnbuckle 116 while maintaining an appropriate compressed state in consideration of the weight of the pipe 152 and the pipe fixture 150. By removing the fixing plate 114, the pipe 152 can be arranged at a predetermined position.

When fluid flows through tubing 152, the weight of the fluid exerts a downward force on tubing 152, which pulls turnbuckle 116 downward. When the spring seat 106 moves downward along with this, as shown in FIG. 7, the restoring force of the spring 108 increases, an upward force is applied, and a constant restoring force can be applied.

As the spring 108 expands and contracts, it also exerts a rotational force on the spring 108 about the spring axis extending in the z direction, which may cause the spring 108 to move in the xy plane. Such movement can cause spring 108 to fall out. Also, depending on the number of turns, pitch, length, coil diameter, center diameter, etc. of the spring 108, a buckling phenomenon may occur during the expansion and contraction process. However, as described above, the support frames 110 are arranged such that the distances d ₁ and d ₂ (see FIGS. 3A and 3B) between the two support frames 110 are also smaller than the outer diameter D of the springs 108, so that the springs 108 can be prevented from bending or buckling. Further, each support frame 110 is formed with a third portion 110c surrounded by the springs 108. As shown in FIG. Therefore, even if the spring 108 moves in the xy plane, the spring 108 is prevented from falling off.

The piping support device 100 having the above configuration can effectively prevent the spring 108 from coming off or buckling without using a cover or the like to cover the side surface of the spring 108 . Therefore, it is possible to reduce the weight of the pipe support device 100, and at the same time ensure high air permeability for the spring 108 and the turnbuckle 116 arranged therein. As a result, corrosion caused by rainwater puddles or the like can be greatly suppressed, and the durability of the pipe support device 100 is improved. Moreover, since substantially the entire spring 108 and turnbuckle 116 can be visually observed from the outside, the states of the spring 108 and turnbuckle 116 can be easily grasped. Therefore, even if each part such as the spring 108 and the turnbuckle 116 is damaged, it can be detected early. This enables easy maintenance work and contributes to high efficiency of maintenance work. Moreover, since the pipe support device 100 can be connected and fixed only by bolting without welding each component, it can be manufactured at low cost.

2. Modification 2-1. Modification 1
The structure of the pipe support device 100 is not limited to the structure described above. A pair of guide rods 112 may be provided to more precisely control the position of spring seat 106, for example as shown in FIGS. 8-9B. In this case, for example, a cover plate 104 connecting the pair of hanger plates 102 may be provided, and guide rods 112 may be fixed to the cover plate 104 so as to extend downward from the cover plate 104 . A cover plate 104 is secured onto the hanger plate 102, for example, as shown in FIGS. 8-9B. Fixing may be done by welding or bolting. The guide rod 112 is a bolt having a head 112a at its upper end, and a screw thread (not shown) is provided on the threaded portion thereof. The cover plate 104 is provided with an opening through which the threaded portion of the guide rod 112 passes but the head 112a does not pass. By inserting the guide rod 112 into this opening and fixing it with the nut 120 , the cover plate 104 and the guide rod 112 are fixed to each other with the guide rod 112 extending downward (z direction) from the cover plate 104 . The x-direction is a direction that connects the central axes of the pair of guide rods 112 extending in the z-direction and is perpendicular to the z-direction.

Each of the pair of end portions 106b of the spring seat 106 is provided with a pair of notches that sandwich the guide rod 112 therebetween. Although not shown, a pair of openings into which the guide rod 112 can be inserted may be provided in the end portion 106b instead of the pair of notches. As an optional configuration, a hole bolt 124 and a nut 126 may be attached to the notch or opening of the spring seat 106 so as to sandwich the spring seat 106 . Washers are appropriately inserted between the hole bolt 124 and the spring washer 106 and between the nut 126 and the spring washer 106 . A slotted bolt 124 and a nut 126 surround the guide rod 112 but slide over the guide rod 112 . Therefore, the spring seat 106 can reversibly slide along the guide rod 112 in the z-direction (i.e., up and down) along with the vertical movement of the pipe, that is, the vertical movement of the turnbuckle 116, without being removed from the guide rod 112. In addition, each guide rod 112 may be provided with two

nuts

122 and 128 that mesh with the screw threads on the upper and lower sides.

Nuts

122 , 128 are positioned in the z-direction by rotating about guide rod 112 . Therefore, by adjusting the positions of the

nuts

122 and 128, the initial position of the spring seat 106 can be determined.

2-2. Modification 2
Alternatively, a single cover plate 104 may be connected to the hanger plate 102 as shown schematically in FIG. In this case, it is not necessary to provide the opening 102a in the hanger plate 102, and instead, the suspension ring 138 may be arranged on the cover plate 104. FIG. A guide rod 112 is provided to extend downward from one cover plate 104 .

2-3. Modification 3
As noted above, in the example shown in FIG. 1 and elsewhere, the pipe support apparatus 100 is provided with at least one spring 108 , which may include multiple springs 108 . Specifically, as shown in FIG. 11, a plurality of springs (here, the first spring 108-1 and the second spring 108-2) overlapping each other in the z direction may be provided between the third portion 110c of the support frame 110 and the spring seat 106. In this case, intermediate rings 109 having openings through which shafts 118 can pass may be placed between adjacent springs 108 . By providing a plurality of springs 108, it is possible to cope with locations where the amount of movement of the piping is large.

In the modified example described above as well, the movement of the spring 108 in the xy plane is restricted by the support frame 110, and without using a cover or the like to cover the side surface of the spring 108, it is possible to allow the spring 108 to slide in the z direction while effectively preventing the spring 108 from coming off or buckling. This contributes to reducing the weight of the pipe support device, reducing the manufacturing cost, and reducing the burden of maintenance work.

<Second embodiment>
In this embodiment, a pipe support device 160 having a structure different from that of the pipe support device 100 described in the first embodiment will be described. Descriptions of configurations that are the same as or similar to those described in the first embodiment may be omitted.

A schematic perspective view of the pipe support device 160 is shown in FIG. 12, and side views thereof are shown in FIGS. As shown in these figures, the pipe support device 160 basically includes a base plate 146, at least one spring 108, a spring seat 106, a hanger plate 102, a plurality of support frames 142, and a turnbuckle 116. The pipe support device 160 may further optionally include a first band plate 140 and a second band plate 144 .

1. Schematic top views of the hanger plate pipe support device 160 are shown in FIGS. 15A and 15B. In FIG. 15B, the hanger plate 102 is indicated by a dashed line for ease of viewing. The hanger plate 102 is a structure for hanging the pipe support device 160 including the base plate 146, the spring 108, the spring seat 106, the support frame 142, the turnbuckle 116, and the like. A suspension ring 138 is provided on the upper surface of the hanger plate 102 in order to exhibit the above function. The shape of the hanger plate 102 on the xy plane can be arbitrarily determined. As shown in FIG. 15B, the shape of the hanger plate 102 in the xy plane may be a cross shape, or may be a polygonal shape including squares and rectangles (not shown).

2. Schematic top and bottom views of the base plate pipe support device 160 are shown in FIGS. 16A and 16B, respectively. For ease of viewing, the hanger plate 102, spring washer 106, and the like are not shown in FIG. 16A. The base plate 146 is a part that supports the spring 108. As shown in FIGS. 16A and 16B, the base plate 146 has a through hole 146a through which the turnbuckle 116 can pass, and the upper surface overlaps the spring 108. As shown in FIG. 16B, the base plate 146 may also have a cross shape, but the shape is arbitrary as long as the above functions can be exhibited, and may be polygons including squares and rectangles, circles, and ellipses.

3. Spring Seat Spring seat 106 is positioned between spring 108 and hanger plate 102 and at least partially overlaps hanger plate 102 . Since the configuration of the spring seat 106 of the pipe support device 160 is the same as the spring seat 106 of the pipe support device 100 described in the first embodiment, detailed description is omitted.

4. Support frames A plurality of support frames 142 extending in the z direction have the function of suppressing the movement of the springs 108 in the xy plane and preventing the buckling phenomenon. Although the number of support frames 110 is not limited, the plurality of support frames 142 can include first through fourth support frames 142-1 through 142-4, for example, as shown in FIGS. 12-15B. The description will be continued below using an example in which the plurality of support frames 142 includes first to fourth support frames 142-1 to 142-4.

In the example shown in these figures, the length (in the z-direction) of each support frame 142 is greater than the spacing between base plate 146 and hanger plate 102 . As such, a plurality of support frames 142 surround the base plate 146 and the hanger plate 102 , with the top and bottom ends of each support frame 142 lying above the base plate 146 and below the hanger plate 102 . However, the length of each support frame 142 may be the same as the distance between the base plate 146 and the hanger plate 102 . In this case, the plurality of support frames 142 may be arranged so as to be sandwiched between the base plate 146 and the hanger plate 102 . Support frame 142 is fixed to hanger plate 102 and base plate 146 by welding or bolting.

Similar to support frame 110 of pipe support device 100 , support frame 142 of pipe support device 160 is also arranged to surround a portion of spring seat 106 and spring 108 . More specifically, the plurality of support frames 142 surrounds the springs 108 in the xy plane and also surrounds the central portion 106a of the spring seat 106 . Furthermore, the first support frame 142-1 and the third support frame 142-3 face each other in the y-direction via one end 106b and part of the central portion 106a. Similarly, the second support frame 142-2 and the fourth support frame 142-4 also face each other in the y-direction via the other end 106b and part of the central portion 106a. Therefore, one end 106b in the y direction is sandwiched between the first support frame 142-1 and the third support frame 142-3, and the other end 106b is sandwiched between the second support frame 142-2 and the fourth support frame 142-4. In addition, the central portion 106a is sandwiched between two arbitrarily selected support frames 142 (see FIG. 15B). Although support frame 142 does not contact spring seat 106 in FIG. 15B , support frame 142 and spring seat 106 may be configured such that at least one of support frames 142 contacts spring seat 106 .

Here, as shown in FIG. 16A, the support frames 142 are arranged so that the distance _d3 in the xy plane between two support frames 142 adjacent in the x direction or the y direction is smaller than the outer diameter D of the spring 108. The distance in the x direction between two support frames 142 adjacent in the x direction (eg, the first support frame 142-1 and the second support frame 142-2, or the third support frame 142-3 and the fourth support frame 142-4), and the distance between the two support frames 142 adjacent in the y direction (eg, the first support frame 142-1 and the third support frame 142-3, or the second support frame 142-2 and the fourth support frame 14). The distance _d3 in the y direction in 2-4) may be the same or different. By adopting such an arrangement, the springs 108 cannot pass between adjacent support frames 142 , thereby preventing the springs 108 from falling off the pipe support device 160 .

The shape of the support frame 142 (the shape in the xy plane) can also be arbitrarily determined. For example, it may be L-shaped as shown in FIGS. In the case of the L-shape, the support frame 142 is preferably formed of angle iron and positioned with its inner side (acute angle side) facing the spring 108 . By arranging the L-shaped support frame 142 in this manner, the distance _d3 can be made smaller, so that the movement of the spring 108 in the xy plane can be more effectively suppressed.

5. The springs and turnbuckles The springs 108 and the turnbuckles 116 can have the same configurations as the springs 108 and the turnbuckles 116 of the pipe support device described in the first embodiment, respectively, so detailed description thereof will be omitted. In the example shown in FIG. 12 and the like, at least one spring 108 includes a plurality of springs 108, and adjacent springs 108 overlap each other vertically via an intermediate ring 109, but the number of springs 108 is not limited, and may be one or three or more.

6. Other Configurations A first band plate 140 is placed over a second band plate 144 and fixed to a plurality of support frames 142 by welding or bolting. As shown in FIGS. 12-14, the first band plate 140 can be placed on the hanger plate 102, in which case an opening is provided for the hanger 138 to be exposed. When the upper end of the support frame 142 is positioned above the hanger plate 102, the support frame 142 passes through this opening. Note that the first band plate 140 may be positioned below the hanger plate 102 . Also, the first band plate 140 and the hanger plate 102 may be in contact with each other or may be separated from each other. In the former case, the first band plate 140 and the hanger plate 102 are fixed together by welding or bolting.

A second band plate 144 is positioned below the first band plate 140 and fixed to the support frame 142 by welding or bolting. Although the second band plate 144 can be positioned above the base plate 146 as shown in FIGS. 12-14, the second band plate 144 can also be positioned below the base plate 146 . Also, the second band plate 144 and the base plate 146 may be in contact with each other or may be separated from each other. In the former case, the second band plate 144 and the base plate 146 are fixed together by welding or bolting.

Since the support frame 142 is surrounded by the first band plate 140 and the second band plate 144, the provision of the first band plate 140 and the second band plate 144 allows the support frame 142 to be more reliably fixed to the hanger plate 102 and the base plate 146.

Also in the piping support device 160 having the above configuration, the end portion 106b of the spring seat is sandwiched between adjacent support frames 142 . Therefore, the support frame 142 works as a guide, and the spring seat 106 can slide up and down along the support frame 142 as the spring 108 expands and contracts. The pair of guide rods 112 may be formed in the pipe support device 100 as well as the pipe support device 100 . In this case, as shown in FIG. 17, a pair of guide rods 112 are attached to the hanger plate 102 and arranged to extend downward from the hanger plate 102 . Since the configuration of the guide rod 112 is the same as that of the pipe support device 100, detailed description is omitted.

Also, as with the piping support device 100, a pair of fixing plates 114 that sandwich a plurality of support frames 142 may be provided in order to preset the springs 108 (FIG. 18). Each fixing plate 114 is provided with an opening through which the spring seat 106 passes and an opening through which the hanger plate 102 passes. When the first band plate 140 is provided, the opening through which the hanger plate 102 penetrates may be configured so that the first band plate 140 also penetrates at the same time.

Also in the pipe support device 160, the turnbuckle 116 and the spring seat 106 vibrate up and down due to the change in mass of the fluid transported in the pipe 152, and the spring 108 expands and contracts accordingly. As a result, the spring 108 is also subjected to a rotational force about the spring axis, which may cause the spring 108 to move in the xy plane. Also, a buckling phenomenon may occur when the spring 108 expands and contracts. However, as described above, since the pipe support device 160 is provided with the support frame 142 for preventing the springs 108 from falling off, the springs 108 can be effectively prevented from falling off. In addition, since the support frame 142 suppresses deformation of the spring 108 other than expansion and contraction, it is possible to effectively prevent the buckling phenomenon.

Similarly to the pipe support device 100, the pipe support device 160 can effectively prevent the springs 108 from coming off and buckling without using a cover or the like to cover the side surfaces of the springs 108. FIG. This contributes to reducing the weight of the pipe support device, reducing the manufacturing cost, and reducing the burden of maintenance work.
