[0002] In existing ceiling installations, when installing the penultimate and tertiary ceiling panels, they are typically attached to each other using flat connectors. However, this method makes it inconvenient to install the penultimate panel onto the edge trim after it's connected to the flat connector, thus hindering its installation. Furthermore, existing methods use adhesive to connect the ceiling panels and the joists, but this method is unreliable, leading to potential detachment between the panels and joists. Additionally, the lifespan of the adhesive needs to be verified, thus limiting the usability of the ceiling panel and joist connection. Summary of the Invention

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0035] Please see Figures 1 to 12 An embodiment of the present invention provides a ceiling installation device comprising a first snap-fit ​​structure 6, a second snap-fit ​​structure 7, a hanging component 5, two wall panels 1, two edge trimming components 2, and at least two ceiling panels 3. The two wall panels 1 are respectively disposed on opposite side walls. The ends of the two edge trimming components 2 near the wall surface are respectively connected to the two wall panels 1. Multiple ceiling panels 3 are sequentially installed along the direction from one wall panel 1 to the other wall panel 1. The end of the first ceiling panel 3 near one side wall is respectively connected to an edge trimming component 2. The bottom end of the first snap-fit ​​structure 6 is connected to the second-to-last ceiling panel 3. The bottom end of the second snap-fit ​​structure 7 is connected to the end of the last ceiling panel 3 away from the other side wall, and its top end is connected to the first snap-fit ​​structure 6. The end of the last ceiling panel 3 near the other side wall overlaps with another edge trimming component 2. The bottom end of the hanging component 5 is connected to the first snap-fit ​​structure 6.

[0036] Here, two wall panels 1 can be fixedly connected to the two sides of the original wall respectively. The two wall panels 1 are fixedly connected to the left and right sides of the original wall respectively. Two edge trims 2 are connected to the two wall panels 1 respectively. Multiple ceiling panels 3 are installed sequentially from one wall panel 1 to another wall panel 1, that is, multiple ceiling panels 3 are installed sequentially from left to right. The end of the first ceiling panel 3 near the left side of the wall is connected to the edge trim 2 located on the left side. The bottom end of the first snap-fit ​​structure 6 is connected to the second to last ceiling panel 3 near the last edge trim 2. One end of a ceiling panel 3 is connected to the bottom of the second snap-fit ​​structure 7 at the end away from the right wall of the penultimate ceiling panel 3, and the top end is connected to the first snap-fit ​​structure 6. The end of the penultimate ceiling panel 3 near the right wall overlaps with the edge trim 2 located on the right side. The bottom end of the hanging piece 5 is connected to the first snap-fit ​​structure 6, thereby suspending the penultimate ceiling panel 3 and the penultimate ceiling panel 3. The two edge trims 2 can respectively trim the edges of the first ceiling panel 3 and the penultimate ceiling panel 3, improving the stability and aesthetics of the ceiling system.

[0037] Specifically, if there are two ceiling panels 3, then the first ceiling panel 3 is the second to last ceiling panel 3. There is one first snap-fit ​​structure 6 and one second snap-fit ​​structure 7, and one hanging piece 5. If there are N ceiling panels 3, where N is an integer greater than or equal to 3, then the last two ceiling panels 3 are connected at their closest points through the first snap-fit ​​structure 6 and the second snap-fit ​​structure 7.

[0038] The edge trimming component 2 includes an edge trimming overlap plate 21, an edge trimming support plate 22, an edge trimming limiting plate 23, an edge trimming fixing plate 24, and a first fastening part 25. The top end of the edge trimming limiting plate 23 is connected to the bottom end of the edge trimming overlap plate 21, and the bottom end is connected to the edge trimming support plate 22. The edge trimming overlap plate 21 overlaps the top end of the wall panel 1, and the end of the ceiling panel 3 located at the end, close to the wall surface, overlaps the edge trimming support plate 22. The edge trimming fixing plate 24 is connected to the top end of the edge trimming overlap plate 21, and the first fastening part 25 is used to fix the edge trimming fixing plate 24 to the wall surface.

[0039] Specifically, the edge-sealing overlap plate 21 overlaps the top of the wall panel 1, so that the wall panel 1 supports the edge-sealing overlap plate 21. The ceiling panel 3 overlaps the edge-sealing support plate 22, so the edge-sealing support plate 22 supports the ceiling panel 3. When the ceiling panel 3 overlaps the edge-sealing support plate 22, the edge-sealing limiting plate 23 can limit the end of the ceiling panel 3 that is close to the wall. The end of the ceiling panel 3 that is close to the wall abuts against the edge-sealing limiting plate 23. The ceiling panels 3 located at the ends are the first ceiling panel 3 and the last ceiling panel 3. The first ceiling panel 3 overlaps with the edge support plate 22 of the edge trim 2 located on the left side. The end of the first ceiling panel 3 near the left wall abuts against the edge limiting plate 23 of the edge trim 2 located on the left side. The last ceiling panel 3 overlaps with the edge support plate 22 of the edge trim 2 located on the right side. The end of the last ceiling panel 3 near the right wall can abut against the edge limiting plate 23 of the edge trim 2 located on the right side. Of course, a first installation gap can also be provided between the end of the last ceiling panel 3 near the right wall and the edge limiting plate 23 of the edge trim 2 located on the right side to prevent the last ceiling panel 3 from squeezing the edge limiting plate 23 and improve the installation efficiency of the last ceiling panel 3.

[0040] Specifically, one end of the first fastening part 25 passes through the edge fixing plate 24 and is fixedly connected to the wall, thereby fixing the edge fixing plate 24 to the wall. The edge overlapping plate 21 is perpendicular to the top of the wall panel 1, the edge limiting plate 23 is perpendicularly connected to the bottom of the edge overlapping plate 21, the edge support plate 22 is perpendicularly connected to the bottom of the side of the edge limiting plate 23 away from the wall, and the first fixing plate 415 is perpendicularly connected to the top of the edge overlapping plate 21. The length of the edge overlapping plate 21 is greater than the thickness of the wall panel 1, which creates a second installation gap between the edge limiting plate 23 and the wall panel 1, preventing the edge limiting plate 23 from squeezing the wall panel 1. The first fastening part 25 can be a screw, bolt, or bolt. The edge trim 2 can be a one-piece molded component.

[0041] This embodiment also includes a first flat connector 4, which includes a third snap-fit ​​structure 41, a fourth snap-fit ​​structure 42, and a first lifting structure 43 whose bottom ends are respectively connected to the third snap-fit ​​structure 41 and the fourth snap-fit ​​structure 42; there are at least three ceiling panels 3, and each ceiling panel 3 has a first insertion slot 31 at both ends; there are multiple hanging members 5; among the multiple ceiling panels 3 from the first ceiling panel 3 to the second to last ceiling panel 3, the bottom ends of the third snap-fit ​​structure 41 and the fourth snap-fit ​​structure 42 are respectively connected to the first insertion slots 31 that are close to each other on two adjacent ceiling panels 3, and the bottom end of the second hanging member 5 is connected to the top end of the first lifting structure 43; the bottom end of the second snap-fit ​​structure 7 is connected to the first insertion slot 31 on the last ceiling panel 3 that is away from another edge trim 2.

[0042] The third snap-fit ​​structure 41 includes a first hook plate 411 and a second insertion slot 412 disposed on the first hook plate 411; the fourth snap-fit ​​structure 42 includes a second hook plate 421 and a third insertion slot 422 disposed on the second hook plate 421; a first insertion through hole 45 is provided between the first hook plate 411 and the second hook plate 421; the first lifting structure 43 includes a first lifting plate 431, a first insertion plate 432 and a second insertion plate 433 respectively connected to the two sides of the first lifting plate 431, the top end of the first lifting plate 431 is connected to the hanging member 5 and the bottom end is inserted into the first insertion through hole 45, the first insertion plate 432 is inserted into the second insertion slot 412, and the second insertion plate 433 is inserted into the third insertion slot 422.

[0043] The third snap-fit ​​structure 41 further includes a third plug-in plate 413, a first limiting plate 414 connected to the top of the third plug-in plate 413, and a first fixing plate 415 connected to the top of the first limiting plate 414. The second snap-fit ​​structure 742 further includes a fourth plug-in plate 423, a second limiting plate 424 connected to the top of the fourth plug-in plate 423, and a second fixing plate 425 connected to the top of the third limiting part. The third plug-in plate 413 and the fourth plug-in plate 423 are respectively plugged into two first plug-in slots 31 that are close to each other on two adjacent ceiling panels 3. The first limiting plate 414 and the second limiting plate 424 respectively abut against one end of the two adjacent ceiling panels 3 that are close to each other. The first flat connector 4 further includes a second fastening part 44, which is used to fix at least one of the first fixing plate 415 and the second fixing part to its corresponding ceiling panel 3.

[0044] The third snap-fit ​​structure 41 further includes a first connecting plate 416 connected to the first mounting plate 411 and the first fixing plate 415 respectively, and a first receiving groove 418 formed by the first mounting plate 411, the first connecting plate 416, and the first fixing plate 415. The fourth snap-fit ​​structure 42 further includes a second connecting plate 426 connected to the second mounting plate 421 and the second fixing plate 425 respectively, and a second receiving groove 428 formed by the second mounting plate 421, the second connecting plate 426, and the second fixing plate 425. The first lifting structure 43 further includes a second support plate 434 connected to the bottom end of the first lifting plate 431, and a first damping plate 435 and a second damping plate 436 connected to the two sides of the second support plate 434 respectively. The first damping plate 435 is inserted into the first receiving groove 418 and abuts against the first connecting plate 416. The second damping plate 436 is inserted into the second receiving groove 428 and abuts against the second connecting plate 426.

[0045] Specifically, the third plug-in plate 413, the first limiting plate 414, and the first fixing plate 415 form the first ceiling connection part, and the fourth plug-in plate 423, the second limiting plate 424, and the second fixing plate 425 form the second ceiling connection part.

[0046] Specifically, the first insertion plate 432 is inserted into the second insertion slot 412, and the second insertion plate 433 is inserted into the second slot, so the first lifting structure 43 can lift the third snap-fit ​​structure 41 and the fourth snap-fit ​​structure 42 respectively. The bottom end of the first lifting plate 431 is inserted into the first insertion through hole 45, which facilitates the insertion of the first insertion plate 432 into the second insertion slot 412 and the insertion of the second insertion plate 433 into the third insertion slot 422. When the second insertion slot 412 and the third insertion slot 422 are both horizontally set, the first insertion plate 432 and the second insertion plate 433 are both horizontally set. At this time, the bottom end of the first hanging plate 411 can be connected to the first lifting connection part, and the bottom end of the second hanging plate 421 can be connected to the second ceiling connection part.

[0047] Specifically, the hanging component 5 may include a hanging rod, the top of which is connected to the top of the wall, the top of the first lifting plate 431 passes through the first insertion hole 45 and protrudes above the third snap-fit ​​structure 41 and the fourth snap-fit ​​structure 42, and the bottom of the hanging rod is fixedly connected to the first lifting plate 431.

[0048] Specifically, the first mounting plate 411 is horizontally arranged, and the second insertion slot 412 may include multiple first base slots, which are respectively inclined and have different inclinations. The multiple first base slots are connected. The first insertion plate 432 may include multiple first insertion substrates, which are interconnected. The multiple first insertion substrates are respectively inclined and have different inclinations. At the node connection between the first lifting structure 43 and the third snap-fit ​​structure 41, different first insertion substrates are matched with different first base slots. Multiple inclinations can help the first insertion plate 432 and the first mounting plate 411 fit more tightly and have better fixation. There can be two first base slots and two first insertion substrates, so the first insertion plate 432 has two types of first insertion substrates with different inclinations. The second mounting plate 421 is horizontally arranged, and the third insertion slot 422 may include multiple second base slots, which are respectively inclined and have different inclinations. The multiple second base slots are connected. The second insertion plate 433 may include multiple second insertion substrates, which are interconnected. The multiple second insertion substrates are respectively inclined and have different inclinations. At the node connection between the first lifting structure 43 and the third snap-fit ​​structure 41, different second insertion substrates are matched with different second base slots. Multiple inclinations can help the second insertion plate 433 and the second mounting plate 421 fit more tightly and have better fixation. There can be two second base slots and two second insertion substrates, so the second insertion plate 433 has two types of second insertion substrates with different inclinations.

[0049] Specifically, the first mounting plate 411 and the second mounting plate 421 can be symmetrically arranged, the second insertion slot 412 and the third insertion slot 422 can be symmetrically arranged, and the first insertion plate 432 and the second insertion plate 433 can be symmetrically arranged. The first insertion plate 432 and the second insertion plate 433 are both horizontally arranged, and the first lifting plate 431 is vertically arranged. The first insertion plate 432 and the second insertion plate 433 form a hook-like structure with the first lifting plate 431.

[0050] Specifically, when there are more than two ceiling panels 3, a first insertion groove 31 is provided at one end of the ceiling panel 3 located at the end, and two first insertion grooves 31 are provided at both ends of the middle ceiling panel 3. Among the multiple ceiling panels 3 from the first ceiling panel 3 to the second to last ceiling panel 3, the first ceiling connection part of a first flat connector 4 located at the left end is connected to the first insertion groove 31 of the first ceiling panel 3, and the second ceiling connection part is connected to the first insertion groove 31 of the second ceiling panel 3; the first ceiling connection part of a first flat connector 4 located in the middle is connected to the first insertion groove 31 of the middle ceiling panel 3, and the second ceiling connection part is connected to the first insertion groove 31 of the other middle ceiling panel 3; the first ceiling connection part of a first flat connector 4 located at the right end is connected to the first insertion groove 31 of the third to last ceiling panel 3, and the second ceiling connection part is connected to the first insertion groove 31 of the second to last ceiling panel 3.

[0051] Specifically, the third plug-in plate 413 and the fourth plug-in plate 423 are respectively plugged into two first plug-in slots 31 that are close to each other on two adjacent ceiling panels 3, so that the third snap-fit ​​structure 41 is connected to one ceiling panel 3 and the fourth snap-fit ​​structure 42 is connected to the other ceiling panel 3. The first limiting plate 414 and the second limiting plate 424 abut against one end of the two adjacent ceiling panels 3 that are close to each other. The first limiting plate 414 can limit the third plug-in plate 413 when it is plugged into the first plug-in slot 31, and the second limiting plate 424 can limit the fourth plug-in plate 423 when it is plugged into the second plug-in slot. The second limiting plate 424 and the fourth limiting plate 62 can abut against each other, thereby limiting the joint between two adjacent ceiling panels 3. The first limiting plate 414 and the third plug-in plate 413 are integrally formed, and the second limiting plate 424 and the fourth plug-in plate 423 are integrally formed, thus realizing the overall installation of the first flat joint 4 and the two ceiling panels 3, and no longer separating them into caulking strips and ceiling base.

[0052] Specifically, the second fastening part 44 can fix the first fixing plate 415 and its corresponding ceiling plate 3. The first fixing plate 415 abuts against the top of the ceiling plate 3 located on the left side, and the second fixing plate 425 abuts against the top of the ceiling plate 3 located on the right side. Thus, the first flat connector 4 can control the height difference between the two ceiling plates 3 and reduce errors. The second fastening part 44 can be a screw, bolt, or bolt.

The first mounting plate 417 and the second mounting plate are symmetrically arranged, as are the first limiting groove 419 and the second limiting groove 429.

[0058] Specifically, the width of the second insertion hole 46 is smaller than the width of the first insertion hole 45, and the width of the first lifting plate 431 is larger than the width of the first support plate 434, thereby improving the overall strength of the first lifting structure 43.

The first snap-fit ​​structure 6 also includes a fourth fastening part 64. One end of the fourth fastening part 64 passes through the third receiving groove 65 and the fourth limiting plate 62 in sequence and is fixedly connected to the first hanging member 5. The other end of the fourth fastening part 64 is received in the third receiving groove 65 to prevent the fourth fastening part 64 from protruding from one side of the fourth limiting plate 62 and affecting the fifth limiting plate 74 abutting against the fourth limiting plate 62.

[0063] Specifically, the fourth insertion slot 751 is downwardly positioned, the top of the fourth insertion plate abuts against the top wall of the fourth insertion slot 751, and the left and right ends of the fourth insertion plate abut against the side walls of the fourth insertion slot 751, respectively. This allows the inner wall of the fourth insertion slot 751 to limit the upper, left, and right sides of the fourth insertion plate, improving the stability of the connection between the second snap-fit ​​structure 7 and the first snap-fit ​​structure 6. The second overlapping plate 73 is horizontally positioned, and the second snap-fit ​​structure 7 also includes a fifth fastening part 76 for fixing the second overlapping plate 73 to one end of the penultimate ceiling plate 3 that is close to the penultimate ceiling plate 3.

[0067] Specifically, the sixth fastening part 83 and the seventh fastening part 84 can both be bolts, screws, or bolts. The fourth fixing plate 82 is perpendicular to the third fixing plate 81, so the hanging connector 8 has an L-shaped structure.

[0068] Specifically, the first snap-fit ​​structure 6, the second snap-fit ​​structure 7, the edge trimming piece, the third snap-fit ​​structure, the fourth snap-fit ​​structure, and the first lifting structure can all be integrally molded components.

[0069] A method for installing a ceiling-mounted device includes the following steps:

[0070] S1: Place the two wall panels 1 on opposite side walls respectively;

[0071] S2: Connect the ends of the two edge trims 2 that are closest to the wall to the two wall panels 1 respectively;

[0072] S3: Install multiple ceiling panels 3 sequentially along the direction from one wall panel 1 to another wall panel 1. Connect the end of the first ceiling panel 3 that is close to one side of the wall to a finishing piece 2. Connect the bottom end of the first snap-fit ​​structure 6 to the second-to-last ceiling panel 3. Connect the bottom end of the second snap-fit ​​structure 7 to the end of the second-to-last ceiling panel 3 that is away from the other side of the wall, and snap the top end to the first snap-fit ​​structure 6. Overlap the end of the second-to-last ceiling panel 3 that is close to the other side of the wall to another finishing piece 2.

[0073] S4: Connect the bottom end of the hanging part 5 to the first snap-fit ​​structure 6.

[0074] Specifically, from left to right, ① connect and fix the first lifting plate 431 to the hanging component 5;

[0075] ② Fix the edge trim 2 on the left side to the wall panel 1 on the left side using bolts;

[0076] ③ The third snap-fit ​​structure 41 and the left ceiling panel 3 are connected and fixed by the second fastening part 44. The third snap-fit ​​structure 41, the left ceiling panel 3, and the first fastening part 25 are assembled on the ground to form a whole.

[0077] ④ Install the whole formed by the third snap-fit ​​structure 41, the second fastening part 44, and the left ceiling panel 3. The left edge of the ceiling panel 3 is attached to the edge trim 2, and the first plug-in plate 432 and the first shock-absorbing plate 435 on the right side are respectively snap-fitted to the first lifting structure 43.

[0078] ⑤ Fix the fourth snap-fit ​​structure 42 to the first lifting structure 43. The connection points of the second overlapping plate 73 and the second plug-in plate 433, and the second mounting plate 427 and the second shock absorber plate 436 are in close contact. The test standard for tight installation is that the first limiting plate 414 and the second limiting plate 424 are flush on the left and right.

[0079] ⑥ Installation of ceiling panel 3 on the right side: Fix ceiling panel 3 to the fourth snap-fit ​​structure 42 on the left side of ceiling panel 3. The connection node is the fourth plug-in plate 423. Keep the connection tight. Repeat the above ③-④ on the right side of ceiling panel 3.

[0080] ⑦ Repeat steps ①-⑥ above until all ceiling panels 3 are installed;

[0081] ⑧ Installation of the second to last panel: The right side of the second to last ceiling panel 3 and the first snap-fit ​​structure 6 are assembled on the ground by nailing. The left side of the second to last ceiling panel 3 is installed as described in step ⑤ above.

[0082] ⑨ The first snap-fit ​​structure 6 and the second-to-last ceiling panel 3 are connected and fixed to the hanging parts by bolts;

[0083] ⑩ Installation of the last panel: Assemble the second snap-fit ​​structure 7 and the last suspended ceiling panel 3 on the ground; connect the last suspended ceiling panel 3 and the second snap-fit ​​structure 7 tightly through the fifth plug-in plate 71;

[0084] ⑪ Fix the edge trim 2 on the right side above the wall panel 1 on the right side;

[0085] ⑫ Secure the hanging connector 8 to the hanging component;

[0086] ⑬ Determine the position of the sixth fastening part 83 through the mounting groove 26, and fix the last ceiling panel 3 and the hanging connector 8 through the sixth fastening part 83;

[0087] ⑭ The last ceiling panel 3 falls down from the left. There is a clear snapping sensation at the connection point between the first snap-fit ​​structure 6 and the second snap-fit ​​structure 7. The first snap-fit ​​structure 6 and the second snap-fit ​​structure 7 are connected by inserting the fourth limiting plate 62 into the fourth insertion slot 751. The installation is then complete.

[0088] Specifically, this application addresses the limitations of existing ceiling installation methods by optimizing the wall-to-ceiling connection nodes and reinforcing the overall stability of the ceiling structure. The application designs a structure for the flat joint of the ceiling panel 3, integrating the caulking strip and the interlocking plate for installation, reducing installation difficulty and accelerating the installation process. The interlocking connection method of the rear-mounted base layer behind the ceiling panel 3 controls the caulking width of the panel. This enhances the stability of the ceiling panel 3 after fixing, and the multi-point fixing method improves the stability and firmness of the panel.

[0089] Specifically, ① at the connection points of the first lifting structure 43 with the third snap-fit ​​structure 41 and the fourth snap-fit ​​structure 42, the upper half is the vertical direction of the fixed module, and the lower half is the horizontal direction of the arc-shaped shock-absorbing module; at the node connection points of the first plug-in plate 432 and the edge overlapping plate 21, and the second plug-in plate 433 and the second overlapping plate 73, the two slopes can help the first plug-in plate 432 and the edge overlapping plate 21, and the second plug-in plate 433 and the second overlapping plate 73 to fit more tightly and have better fixation;

[0090] ② At the connection between the first mounting plate 417 and the first damping plate 435, and the second mounting plate 427 and the second damping plate 436, when the first ceiling plate 3 is connected to the hanger and generates horizontal vibration amplitude, the arc design of the first damping plate 435 and the second damping plate 436 can help reduce horizontal vibration; the first damping plate 435 and the first mounting plate 417, and the second damping plate 436 and the second mounting plate 427 are not completely fitted together to resist the effects of horizontal deformation;

[0091] ③ At the connection points of the third snap-fit ​​structure 41 and the fourth snap-fit ​​structure 42 with the two ceiling panels 3, the primary purpose is to install them as a whole, without separating them into caulking strips and ceiling base layers; in addition, it can control the height difference between the panels and reduce errors.

[0092] ④ The first snap-fit ​​structure 6 and the second snap-fit ​​structure 7, through the tight fit of the fourth limiting plate 62 and the fourth insertion groove 751, make the second to last ceiling panel 3 and the first to last ceiling panel 3 installed flat;

[0093] ⑤ The connection between the first snap-fit ​​structure 6 and the hanging part 5 requires bolts and nuts for fixing. One end of the bolt passes through the hanging part 5 and the fourth limiting plate 62 and is screwed to the nut. In order to prevent the nut from protruding from the side of the fourth limiting plate 62 near the fifth limiting plate 74, there is a third receiving groove 65 for hiding the nut.

[0094] ⑥ The third limiting plate 72 and the fifth plug-in plate 71 are integrally formed, and the caulking strip and the plug-in plate are installed as a whole;

[0095] ⑦ The last ceiling panel 3 and the edge support plate 22 of the edge trim 2 on the right side are fixedly connected by screws. The mounting groove 26 is used to confirm the position of the screws and also serves as a concealment function to hide the screws.

[0096] ⑧ The third fixing plate 81 and the fourth fixing plate 82 form an L-shaped component, which makes the fixing effect more obvious;

[0097] ⑨ The shape design of the edge trim 2: one end is connected to the original wall, and the other end needs to support the ceiling panel 3, and the distance between the edge of the ceiling panel 3 and the wall panel needs to be controlled.

[0098] ⑩ At the mounting groove 26, nails need to be driven into the surface of the ceiling panel 3 to connect with the first fixing plate 81. This is to strengthen the fixation and increase the service life.

[0099] The above-described contents can be implemented individually or in various combinations, and these variations are all within the protection scope of this invention.
