Description

Odor blocking device for rainwater manhole}

The present invention relates to an odor blocking device for a sewage rain gutter and an installation method thereof, and more particularly, to a odor blocking device and an installation method for blocking odor generated from a sewage rain gutter through which domestic sewage or rainwater flows.

Sewage rainwater gutters are generally installed at certain intervals along roads such as housing complexes or shopping malls, and serve to collect rainwater or sewage and move them to a sewage treatment plant.

10a and 10b show a cross section of a conventional sewer rain gutter, in which a sewage pipe 30 is connected downward from the lower center of the rain gutter 10 in a certain space, such as a rectangular parallelepiped barrel buried underground (FIG. 10a), It is a structure in which sewage pipes 30 are connected to both sides of the rain gutter 10 (FIG. 10B). A cover 20 having a grid 21 is disposed on the top of the rain gutter 10 so that rain water is easily introduced and foreign substances are not introduced.

This rain gutter is easy to install and easy to inflow of rainwater, so it is a form that is widely used, but when the odor flows back through the sewer pipe 30 connected to the rain gutter 10, this odor is caused by the cover 20 It is discharged to the ground as it is through between the gratings 21.

In order to block the odor flowing back from the sewer pipe of the sewer rain gutter, various types of odor blocking devices have been devised in the related art. For example, Utility Model Registration No. 20-0342682 discloses an odor blocking device in which a floating plate for blocking odor made of synthetic resin such as urethane or polyethylene covers a sewer pipe.

However, when the floating plate adheres to the floor, such an odor blocking device may block the sewage pipe and prevent rainwater from being discharged. Furthermore, there is a problem in that the sewer pipe is exposed and still smells because there is no way to accurately return to the position where the sewer pipe is blocked when the floating plate floats due to the inflow of rainwater and then sits down on the floor after the inflow of rainwater is stopped.

Moreover, in recent years, there has been a lot of torrential rain in the Korean Peninsula, and the conventional odor blocking device has a problem of not effectively discharging it and blocking the sewage pipe when a large amount of sewage flows in a short time, such as during such a torrential rain.

On the other hand, in order to solve the above problems, the inventors of the present application have proposed an odor blocking device in Patent Application No. 10-2019-0173043 to block odor generated from a sewage rain gutter but to allow sewage to be well discharged.

Therefore, the present invention has been made to solve the problems of the prior art, to provide an odor blocking device for a sewage rain gutter that can normally block odors rising from a rain gutter and freely drain in case of rain.

Another object of the present invention is to provide an odor blocking device for a sewage rain gutter that can effectively block odor even when a large amount of sewage is concentrated, such as in torrential rain.

Another object of the present invention is to improve the odor blocking device disclosed in Patent Application No. 10-2019-0173043, to provide an odor blocking device that is easier to install and can be easily installed even when the rainwater gutter is deep and its installation method is to provide

In order to achieve the object of the present invention as described above, the odor blocking device of the sewer rain gutter according to one feature of the present invention includes a fixing part fixed to the side wall or cover of the rain gutter; and a moving module that is guided by the fixing unit and slides.

The moving module includes a guide tube in the form of a pipe formed to a predetermined length; an upper fixing member fixed to an upper end of the guide tube; a disc-shaped upper member including an opening of a first diameter formed in the center, and a connecting portion formed to cross the opening and having a first through hole in the center of which the guide tube is inserted; a plate-like lower member having a second diameter and having a second through hole into which a guide tube is inserted; a spring extrapolated to the guide tube; and a lower fixing member fixed to the lower end of the guide tube.

At this time, the first diameter is smaller than the diameter of the sewage pipe, and the second diameter is larger than the first diameter and smaller than the diameter of the sewage pipe.

An odor blocking device for a sewer rain gutter according to another feature of the present invention includes an auxiliary plate formed in a size to cover the rain gutter above a sewer pipe and having a discharge hole formed at a predetermined position; A fixing part fixed to the side wall or cover of the rain gutter; and a moving module that is guided by the fixing unit and slides. At this time, the first diameter is smaller than the diameter of the discharge hole, and the second diameter is larger than the first diameter and smaller than the diameter of the discharge hole.

A fixed bar fixed to the side wall or cover of the rain gutter; and a fixing bar formed to a predetermined length in a vertical direction from the fixing bar.

The guiding tube of the moving module is extrapolated to the fixing rod so that the moving module can slide. The length of the fixed rod is longer than the depth of the rain gutter.

When there is no inflow of sewage, the lower member closes the opening of the upper member by the compressive force of the spring, and the upper member blocks the discharge hole of the sewage pipe or auxiliary plate.

It is preferable that the upper member has a substantially disc shape and the thickness decreases toward the outer side in the radial direction. The lower member is preferably formed in a cylindrical or truncated conical plate shape.

In addition, the upper member and the lower member have a hollow shape, and it is preferable that the inside is in a vacuum state, but the inside may be filled with a material having a specific gravity smaller than water. Alternatively, the upper member and the lower member may be integrally formed from a material having a specific gravity less than water.

The connecting portion of the upper member may be formed in a straight or cross shape on the upper or lower surface of the upper member, or may be formed in a triangular shape.

The upper fixing member of the moving module may be selected from among nuts, washers, O-rings, and rubber caps, and may be formed of two or more members.

A method of installing an odor blocking device according to another feature of the present invention includes placing a mobile module over the sewer pipe or discharge hole; coupling the fixing unit to the moving module; And fixing the fixing part to the side wall or cover of the rain gutter.

In this case, before the step of locating the moving module, a step of fixing the floor auxiliary member to the floor around the sewage pipe or the discharge hole may be further included. The floor auxiliary member includes a flange portion disposed on the floor around the sewer pipe.

The present invention blocks the odor generated from the sewer rain gutter, but allows the sewage to be discharged well, and can be simply installed and used in the existing rain gutter.

The odor blocking device of the present invention normally closes the sewer pipe to block the spread of odor, and when sewage or rainwater flows in, the sewage pipe is discharged through the opening of the upper member or the upper member and/or the entire mobile module floats due to buoyancy, thereby opening the sewer pipe. Sewage or rainwater is quickly discharged, and the discharge of sewage is smooth while fundamentally blocking odors generated from the sewage pipe.

In addition, the odor blocking device of the present invention can effectively drain a large amount of water due to torrential rain by completely opening the sewage pipe by floating not only the upper member but also the lower member by buoyancy during torrential rain. Therefore, the odor blocking device of the present invention can effectively drain water even during heavy rain as well as blocking odor in usual times.

Moreover, in the odor blocking device of the present invention, the fixing part and the movable module are formed separately, and the movable module slides along the fixing part so that drainage is smoothly performed, and the odor blocking device is installed in the center of the sewage pipe of the rain gutter. It's easy. In particular, the odor blocking device of the present invention can be easily installed even in a deep rain gutter.

Hereinafter, an embodiment in which a person skilled in the art can easily practice the present invention will be described in detail with reference to the accompanying drawings. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. In order to clearly describe the present invention in the drawings, parts irrelevant to the description are omitted, and the same reference numerals are used for the same or similar components throughout the specification.

First, an odor blocking device according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 3 . 1 is a perspective view of an odor blocking device according to a first embodiment of the present invention, FIG. 2 is an exploded perspective view, and FIG. 3 is a cross-sectional view of the mobile module 1 taken along line II in FIG. 2 .

The odor blocking device according to the first embodiment of the present invention largely consists of a fixing part 400 and a moving module 1.

The fixing part 400 is composed of a fixing bar 410 coupled to the rain gutter wall or the cover 20 covering the rain gutter, and a fixing bar 420 extending vertically from the fixing bar 410. The fixing rod 420 has a length extending into the sewage pipe 30 longer than the depth of at least the rain gutter. Therefore, after the fixing rod 420 is installed, its lower end is located in the sewage pipe 30. The fixing bar 420 may be coupled to the fixing bar 410 using a nut, but is not limited thereto, and may be fixed to the fixing bar 410 by welding or the like.

The moving module 1 is guided by the fixing rod 420 of the fixing part 400 and slides, and normally blocks the sewage pipe 30 of the rain gutter. The moving module 1 includes a pipe-shaped guide tube 310 having a predetermined length, an upper end fixing member 340 fixed to an upper end of the guide tube 310, and an upper member that is guided by being extrapolated to the guide tube 310. 100 and lower member 200, a spring 330 extrapolated to the guide tube 310, and a lower fixing member 320 fixed to the lower end of the guide tube.

The odor blocking device according to the first embodiment of the present invention is an embodiment suitable for a structure in which the sewage pipe 30 is connected to the lower center of the rain gutter 10 as shown in FIG. 10a.

The upper member 100 is a substantially disc-shaped member in which an opening 150 having a first diameter d1 is formed in the center. The upper member 100 is formed so that its thickness becomes thinner toward the outer side in the radial direction, so that rainwater and the like do not accumulate in the upper member 100 and flow well to the surroundings. Although several steps are formed on the upper surface 130 of the upper member 100 in the drawing, the shape of the upper surface 130 may form various shapes that allow rainwater to flow well if not limited to these shapes. A connection portion 120 is formed in the upper member 100 to cross the opening 150 , and a first through hole 110 into which the guide tube 310 is inserted is formed in the connection portion 120 . The connecting portion 120 is shown to be formed in a triangular shape, but is not limited thereto and may be formed in a straight or cross shape.

The upper member 100 may be made of a hollow steel material such as aluminum or stainless steel using a plate. Alternatively, it may be made hollow using a plastic with a high refractory temperature, for example polyphenylene sulfide (PPS). Since the upper member 100 must float on the sewage for smooth drainage when the rainwater inlet 10 is filled with sewage, a hollow shape is preferable. In addition, when the upper member 100 is formed in a hollow form, the inside is preferably in a vacuum state, but if necessary, a filler having a specific gravity smaller than that of water, for example, a foam material such as Styrofoam, can be filled therein can The connecting portion 120 may be integrally formed with the upper member 100, or may be separately formed in the form of a strip and coupled by a suitable adhesive or a coupling tool such as a screw.

The lower member 200 is formed in a cylindrical plate shape having a second diameter d2 and has a second through hole 210 formed in the center. Like the upper member 100, the lower member 200 may be made of a hollow steel material such as aluminum or stainless steel using a plate. Alternatively, it may be made hollow using a plastic having a high refractory temperature such as PPS. The lower member 200 has a hollow shape like the upper member because it must float on the rainwater when the rainwater inlet 10 is filled with a certain amount or more for smooth drainage when a large amount of sewage such as torrential rain flows in.

6A to 6C are examples in which the lower member 200 is formed in the shape of a cylinder, a truncated cone of upper and lower beams, and a plate of a truncated cone of upper and lower beams, respectively. 6A to 6C , the second diameter of the lower member 200 means the diameter of the surface of the upper member 100 that contacts the opening 150, that is, the upper surface.

As shown in FIG. 3 , the second diameter d2 of the lower member 200 is slightly larger than the first diameter d1 of the opening 150 of the upper member 100, so that the lower member 200 has the upper member 100 ) can block the opening 150. The second diameter d2 of the lower member 200 is smaller than the diameter of the sewage pipe of the rain gutter to be installed. That is, the first diameter d1 < the second diameter d2 < the sewage pipe diameter < the diameter of the upper member 100 increases in the order. Therefore, the lower member 200 is located in the sewer pipe at a position just below the bottom of the rain gutter 10 during installation.

The guide tube 310 has a pipe shape having a predetermined length, and upper and lower fixing members 340 and lower fixing members 320 are coupled to the upper and lower ends, respectively, so that the upper member 100 and the lower member 100 inserted into the guide tube 310 are connected. Movement of the member 200 may be restricted.

The upper fixing member 340 is preferably a nut, and is coupled with a screw thread formed in the guide tube 310 to limit the upward movement of the upper member 100. In the drawing, the upper fixing member 340 is shown as a nut, but is not limited thereto, and restricts the movement of the upper member 100 at the top of the guide tube 310, such as a stopper, washer, O-ring, rubber cap, etc. It is possible as long as it is, and it is also possible to use two or more of them. For example, as shown in FIG. 7 , the upper fixing member 340 may be formed of a nut 341 coupled to a screw thread formed in the guide tube 310 and a rubber cap 342 on the nut 341 . When the rubber cap 342 is formed up to a position above the nut 341, it is possible to block odor rising between the fixing rod 420 and the guide tube 310.

The spring 330 is a compression spring having a slightly larger diameter than the diameter of the guide tube 310 . While the lower end of the spring 330 is supported by the lower fixing member 320, the upper end supports the lower member 200, and provides an elastic force that allows the lower member 200 to be pressed downward by the inflow of sewage. When there is no inflow of sewage, the lower member 200 is raised by the compressive force to return the lower member 200 to close the opening of the upper member 100.

The lower fixing member 320 is preferably a circular plate having an open center and may be fixed to the lower end of the guide tube 310 by welding or the like, and prevents the spring from escaping to the lower end of the guide tube 310 . One end of the spring 330 may or may not be fixed to the lower fixing member 320 . Alternatively, the lower fixing member 320 is formed of a screw thread formed at the lower end of the guide tube 310 and a nut coupled thereto, similarly to the upper fixing member 340, or by an interference fit of a disk having an open center. can be combined.

The moving module 1 sequentially inserts the spring 330, the lower member 200 and the upper member 100 into the guide tube 310 while the lower fixing member 320 is fixed to the lower end of the guide tube 310. After that, the top fixing member 340 is coupled to the top of the guide tube 310 to form it. In the coupled state, the spring 330 is in a partially compressed state, for example, in a compressed state of about 10-50%. Therefore, in the coupled state, the moving module 1 applies an upward force to the lower member 200 and the upper member 100 so that the lower member 200 and the upper member 100 come into contact with each other so as to move the lower member 200 and the upper member 100 into contact with each other. Member 200 closes opening 150 of top member 100 . In addition, when an external force acts downward on the lower member 200 in a state in which the moving module 1 is coupled, the spring 330 may be further compressed.

The moving module 1 is inserted into the fixing rod 420 of the fixing part 400, and specifically, the guide pipe 310 of the moving module 1 is extrapolated to the fixing rod 420.

On the other hand, although not shown, a GPS chip or IoT sensor is installed in the mobile module 1 or the fixing unit 400 to determine the location where the odor blocking device is installed and to diagnose the drainage state. For example, these chips or sensors may be fixed in the rubber cap 342 of the upper fixing member 340 of FIG. 7 or may be fixed inside the upper member 100 or the lower member 200 .

4a to 4e show a process of installing the odor blocking device according to the first embodiment of the present invention to a rain gutter.

First, as shown in FIG. 4A, the floor auxiliary member 600 is placed on the floor above the sewage pipe 30 and then fixed. This floor auxiliary member 600 is useful when the bottom of the rain gutter 10, in particular, the floor around the sewage pipe 30 is not flat. If the floor around the sewer pipe 30 is not flat and is formed unevenly, the lower surface 140 of the upper member 100 may not adhere to the floor around the sewer pipe 30 and a gap may occur. When the gap between the 140 can come up. Therefore, when the floor around the sewage pipe 30 is not flat, the bottom auxiliary member 600 may be used to flatten a portion where the lower surface 140 of the upper member 100 touches the floor.

As shown in FIG. 9, the floor auxiliary member 600 may be formed in a funnel shape having a flange, but is not limited to this shape, and the lower surface 140 of the upper member 100 is in contact with the floor. It can be formed as a cylinder with a flattening flange, or alternatively it can be formed with only a flange. At this time, the diameter of the funnel or cylindrical portion is equal to or slightly smaller than the diameter of the sewage pipe 30. In order to fix the floor auxiliary member 600 to the floor above the sewage pipe 30, cement, caulking agent, silicone or other adhesives may be used, and the floor may be screwed together.

On the other hand, when the floor around the sewer pipe 30 is flat, the floor auxiliary member 600 may not be used, and the installation process of FIG. 4B may be started immediately.

Next, as shown in FIG. 4B, the mobile module 1 is placed on the sewage pipe 30 of the rain gutter or on the floor auxiliary member 600. Preferably, the center of the mobile module 1, that is, the guide pipe 310 is aligned with the center of the sewage pipe 30. Since the movable module 1 is positioned before being coupled with the fixing bar 420, it is convenient to adjust the position of the movable module. At this time, since the diameter of the upper member 100 is larger than the diameter of the sewage pipe 30 of the rain gutter 10, it can be placed on the sewer pipe 30.

Then, as shown in FIG. 4c, after inserting the fixing rod 420 of the fixing part 400 into the guide tube 310 of the moving module 1, as shown in FIG. 4d, the grid of the rain gutter cover 20 ( 21) by fixing the fixing bar 410 of the fixing part 400 with bolts and nuts to complete the installation as shown in FIG. 4e.

Alternatively, only the fixing rod 420 of the fixing part 400 may be directly fixed to the grid 21 of the rain gutter cover 20 using a separate fixing piece or a fixing method such as welding. As another alternative, the fixing bar 410 may be made into a 'c' shape with both sides bent and fixed to the side wall of the rain gutter with screws or the like.

The odor blocking device according to an embodiment of the present invention is formed by separating the fixing part 400 and the moving module 1, and when installing the odor blocking device, the guide tube 310 is inserted into the fixing rod 420 and installed. , the installation operation becomes simple and convenient. That is, since the mobile module 1 is first placed on the sewer pipe 30 and then the fixing bar 420 is inserted, it is very easy to align the center of the mobile module 1 with the center of the sewer pipe 30. do. This is especially useful when the rain gutters are deep.

In addition, when the fixing part 400 is coupled to the rain gutter cover with bolts or the like, it can be easily installed because a separate drilling operation is not required.

When the installation of the odor blocking device according to the embodiment of the present invention is completed and sewage does not flow in, the mobile module 1 closes the sewer pipe 30 by its own weight as shown in FIG. 4E. That is, the lower surface 140 of the upper member 100 blocks the sewage pipe 30, and the opening 150 of the upper member 100 is closed by the lower member 200 by the compressive force of the spring 330. Therefore, since the sewer pipe 30 is closed by the upper member 100 and the lower member 200 of the moving module 1, odor is blocked.

In such a state where there is no sewage inflow, the odor blocking device has the lower surface 140 of the upper member 100 blocking the sewage pipe 30 and the lower member 200 blocking the opening 150 of the upper member 100. By positioning to block, the bad smell rising from the sewage pipe 30 is blocked.

On the other hand, the moving module 1 can move up and down along the fixing rod 420 in a state of being extrapolated to the fixing rod 420, and the upper member 100 and the lower member 200 are each a guide tube 310 Since the movement in the lateral direction is restricted by the first through hole 110 and the second through hole 210 into which ) is inserted, the movement in the up and down direction along the guide tube 310 is possible, so that it can be drained when it rains.

Next, an operation of the odor blocking device according to the first embodiment of the present invention when draining will be described with reference to FIGS. 5A to 5C. First, FIG. 5A is a view for explaining drainage in a state in which rain has not yet accumulated in the rain gutter 10 since it has started to rain. That is, when it rains, when the rain first enters the opening 150 of the upper member 100, the rain presses the lower member 200. The upper member 100 is limited in its downward movement by the bottom of the rain gutter 10, but the lower member 200 is pressed by rainwater and the spring 330 is compressed, and the opening 150 of the upper member 100 and The space between the lower members 200 is widened and rain falling through this gap is drained.

5B is a case where sewage starts to accumulate in the rain gutter 10, and when sewage accumulates in the rain gutter 10, buoyancy acts on the upper member 100 so that the upper member 100 floats upward. Therefore, it flows not only through the opening 150 of the upper member 100 but also into the periphery and flows into the sewage pipe 30.

Next, FIG. 5C is a view for explaining a case where a large amount of sewage is introduced due to torrential rain or the like. When a large amount of sewage flows in, a considerable amount of sewage accumulates in the rain gutter 10, and at this time, not only the upper member 100 but also the lower member 200 are floated by buoyancy, so that the mobile module 1 itself is fixed rod ( 420) to float upward. The sewer pipe 30 is completely opened without blockage by the mobile module, so that drainage is smooth.

As described above, in the odor blocking device according to the embodiment of the present invention, the upper member 100 and the lower member 200 not only move up and down along the guide tube 310, but also the moving module 1 itself is fixed by the fixing rod 420. By moving up and down along, the sewage pipe 30 is closed or opened according to the amount of sewage flowing into the rain gutter.

There is no inflow of sewage, the sewage is completely discharged, and as the buoyancy caused by the sewage disappears, the moving module 1 descends along the fixing bar 420 and is positioned in place as shown in FIG. 4e. That is, the upper member 100 closes the sewage pipe 30 and the lower member 200 closes the opening 150 of the upper member 100 by the compressive force of the spring 330, thereby blocking the outflow of odor again. do.

Next, referring to FIG. 8 , an odor blocking device according to a second embodiment of the present invention will be described. The odor blocking device according to the second embodiment is an embodiment suitable for a structure in which sewage pipes 30 are connected to both sides of the rain gutter 10 as shown in FIG. 10B.

The odor blocking device includes a moving module 1, a fixing part 400, and an auxiliary plate 500. At this time, the configuration of the moving module 1 and the fixing part 400 is similar to that of the first embodiment.

The auxiliary plate 500 is a plate-like member capable of covering the inside of the rain gutter 10 from above the sewage pipes 30 on both sides. The auxiliary plate 500 may be directly fixed to the sidewall of the rain gutter 10 with screws or the like, and legs are formed at each corner of the rain gutter 10 to be installed above the sewer pipes 30 on both sides.

A discharge hole 510 having a larger diameter than the opening 150 of the upper member 100 is formed at a predetermined position in the auxiliary plate 500 . The discharge hole 510 plays the same role as the sewage pipe formed downward in the first embodiment.

In the odor blocking device according to the second embodiment of the present invention, after first installing the auxiliary plate 500 , the moving module 1 is centered and positioned over the discharge hole 510 of the auxiliary plate 500 . Thereafter, the fixing bar 420 of the fixing part 400 is inserted into the guide tube 310 of the moving module 1, and then the fixing bar 410 of the fixing part 400 is inserted into the grid of the rain gutter cover 20. Complete the installation by fixing with bolts and nuts.

At this time, the second diameter (d2) of the lower member 200 is slightly larger than the first diameter (d1) of the opening 150 of the upper member 100 to block the opening 150 of the upper member 100, The second diameter d2 is smaller than the diameter of the discharge hole 510 . That is, the first diameter d1 < the second diameter d2 < the diameter of the discharge hole 510 < the diameter of the upper member 100 increases in the order.

In a state in which there is no inflow of sewage, the odor blocking device blocks the discharge hole 510 with the lower surface 140 of the upper member 100 and the lower member 200 blocks the opening 150 of the upper member 100. By positioning so as to, the odor rising from the sewage pipe 30 is blocked by the upper member 100 and the lower member 200.

The odor blocking device according to the second embodiment is particularly suitable when the sewer pipe 30 is connected to both sides of the rain gutter 10 and is useful because it can be installed regardless of the arrangement of the sewer pipe.

The odor blocking device according to the present invention blocks odors generated from a sewage rain gutter, but allows sewage to flow well, and can be simply installed and used in an existing rain gutter. In addition, in normal times, the mobile module 1 closes the sewage pipe 30 or the discharge hole 510 by its own weight to block the spread of odor, and when sewage or rainwater flows in, the upper member ( 100), the lower member 200, and the moving module 1 themselves move up and down due to their own weight and buoyancy, thereby opening the sewage pipe, so that sewage or rainwater is quickly discharged, fundamentally blocking the odor generated from the sewage pipe, Discharge has an easy effect.

In addition, the odor blocking device of the present invention can effectively drain a large amount of water due to torrential rain by completely opening the sewage pipe by floating not only the upper member but also the lower member by buoyancy during torrential rain. Therefore, the odor blocking device of the present invention can effectively drain water even during heavy rain as well as blocking odor in usual times.

Moreover, the odor blocking device of the present invention greatly simplifies the installation work. By forming the fixing part 400 and the moving module 1 separately and installing the odor blocking device by inserting the guide tube 310 into the fixing bar 420, the installation work becomes simple and convenient. That is, since the mobile module 1 is first placed on the sewer pipe 30 and then the fixing bar 420 is inserted, it is very easy to align the center of the mobile module 1 with the center of the sewer pipe 30. It is easy to install even when the depth of the rain gutter is deep.

Moreover, even when the floor around the sewage pipe 30 is not flat, by using the floor auxiliary member 600, the odor is completely eliminated by contact between the floor auxiliary member 600 and the lower surface 140 of the upper member 100. can be blocked.

In addition, when the fixing part 400 is coupled to the rain gutter cover with bolts or the like, it can be installed more easily because a separate drilling operation is not required.

Although the technical features of the present invention have been described above with reference to specific embodiments, those skilled in the art can make various modifications and variations within the scope of the technical idea according to the present invention. It's obvious.
