Description

Technical Field

[0001] This invention relates to the field of men's trousers technology, and more specifically to a method for designing sheet-type three-dimensional trousers. Background Technology

[0002] In the field of clothing design, the structural design of men's trousers plays a crucial role. This is not only related to the aesthetics of the clothing, but also directly to the wearer's comfort and freedom of movement.

[0003] Current men's trouser designs prioritize style and appearance, with less consideration for the actual needs and changes in the human body during movement. This leads to discomfort and even restricted movement in trousers due to poor design. For example, if the fabric and structure of the trousers cannot adapt to bending and stretching movements, it will create a feeling of tightness, affecting the wearer's comfort. During daily activities such as walking and running, the thighs, calves, and knees all bend and stretch to varying degrees. If the trousers' design does not adequately accommodate these movements, the wearer will feel restricted during exercise, and the comfort and freedom of movement will be severely limited. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the shortcomings of the existing men's trouser cutting methods in terms of poor three-dimensional shape and wearing comfort, thereby providing a one-piece three-dimensional trouser design method.

[0005] To solve the above-mentioned technical problems, the present invention provides a method for designing three-dimensional trousers, comprising the following steps: S1: drawing dividing lines on the trouser piece, the trouser piece having a front piece and a back piece connected together, a center line between the front piece and the back piece forming a middle trouser line, the front piece having a first center line, and the back piece having a second center line; the trouser piece also has: a hip line, a crotch line, and a knee line;

[0006] Draw a first dividing line, with the intersection of the first trouser center line and the knee circumference line at point A, and draw a line from point A to the edge above the hip circumference line of the back piece;

[0007] Draw a second dividing line. The intersection of the second center line of the pants and the knee line is B. Draw a line from point B to the edge below the knee line of the back piece.

[0008] Draw a third dividing line, which connects point B to the edge between the back panel's cross neckline and hip line;

[0009] S2: Extract the cut pieces:

[0010] Cut the front piece along the first dividing line and the knee circumference line to extract the first cut piece;

[0011] Cut the back piece along the second and third dividing lines to extract the second piece;

[0012] Cut the back piece along the knee circumference line and extract the third piece;

[0013] S3: Sewing the trouser pieces:

[0014] Rotate the first cut piece by an angle α with point C as the center toward the outside of the front piece, where point C is the outer end point of the knee circumference line on the front piece;

[0015] Rotate the third piece of fabric around point D towards the outside of the back piece by an angle β, where point D is the intersection of the center line of the pants and the knee line.

[0016] Fill in the triangular space formed by rotation between the first and third cut pieces, and then sew the first dividing line between the first and third cut pieces;

[0017] After cutting the second piece to the appropriate size, sew it back to its original position along the second and third dividing lines.

[0018] Preferably, the trouser piece has a first cutting seam extending downward along its upper edge. The first cutting seam is located on the center line of the trousers and is connected to the first dividing line. When sewing the trouser piece, the first cutting seam is sewn together.

[0019] Preferably, the upper edge of the trouser piece has a downwardly extending second cutting seam, which is located on the back piece near the second center line of the trousers. The second cutting seam is connected to the second dividing line, and the second cutting seam is sewn together when the trouser piece is sewn.

[0020] Preferably, when drawing the dividing lines on the trouser piece, the method further includes:

[0021] Draw a fourth dividing line, which is set at the pocket position of the trouser piece. The intersection of the center trouser line and the hip line is E. The starting point of the fourth dividing line is located at the upper edge of the front piece, between the first trouser line and the center trouser line. After passing through point E, the fourth dividing line extends to intersect with the second dividing line.

[0022] When extracting the trouser piece, the first piece is cut along the fourth dividing line, and the fourth piece is extracted.

[0023] When sewing the trousers, after cutting the fourth piece to the appropriate size, sew it back to its original position along the fourth dividing line and the second dividing line.

[0024] Preferably, the fourth dividing line is a straight line.

[0025] Preferably, the first dividing line is an arc that protrudes toward the front piece.

[0026] Preferably, the second dividing line is a straight line.

[0027] Preferably, the third dividing line is an arc that protrudes toward the front piece.

[0028] Preferably, the α angle and the β angle are the same.

[0029] Preferably, the α angle and the β angle are 5-15°.

[0030] The technical solution of this invention has the following advantages:

[0031] 1. The method for designing three-dimensional pants provided by the present invention involves setting a first dividing line, a second dividing line, and a third dividing line. After cutting out the first, second, and third cut pieces, the first and third cut pieces are rotated to form protruding and recessed parts, which makes the pants have a better three-dimensional effect. The protruding and recessed parts are used to adapt to the needs of human movement, ensuring the consistency of the three-dimensional effect and improving the comfort when wearing them.

[0032] 2. The three-dimensional trouser design method provided by the present invention has a first cutting seam with a certain width. After the first cutting seam is sewn, the trouser piece has a certain waist-cinching effect at the waist, so that the three-dimensional effect is just right after wearing.

[0033] 3. The method for designing three-dimensional pants in this invention involves the first and second cutting seams located on the fourth piece. After the fourth piece is removed, it is sewn separately. The third and first pieces are made simultaneously while the fourth piece is being sewn, which can speed up the overall production process of the pants. Attached Figure Description

[0048] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] The method for designing sheet-like three-dimensional pants provided in this embodiment is used to cut fabric and sew it into pants.

[0050] like Figure 1 , Figure 2 As shown, in a specific embodiment of the panel-type three-dimensional pants design method provided in this example, the specific structure of the panel-type three-dimensional pants includes: a front piece 1 and a back piece 2 capable of being sewn into a single pant leg, wherein the front piece 1 is located at the front of the pants, with the knee position located at the front piece 1. The back piece 2 is located at the back of the entire pant leg, with the back of the knee located at the back piece 2. Figure 2As shown, after aligning and sewing the front piece 1 and the back piece 2 into a single unit, a center trouser line 3 is formed between the front piece 1 and the back piece 2. The center trouser line 3 refers to the line between the long sides of the front piece 1 and the back piece 2 after the front and back pieces 2 are joined together. The front piece 1 has a first center trouser line 4, and the back piece 2 has a second center trouser line 5. The first center trouser line 4 is the line formed by the front piece 1 from halfway down the waistband to halfway down the hem, and the second center trouser line 5 is similarly defined. The trouser pieces also have: a hip line 6, a crotch line 7, and a knee line 8. The hip line 6, crotch line 7, and knee line 8 are three common lines in existing trouser pieces. The hip line 6 refers to the line at the hip position; the crotch line 7 is the seam where the front and back of the trousers are sewn together, and is also the lowest point when the two trouser legs are sewn together; the knee line 8 refers to the line at the knee position. These three lines are key factors in the comfort and fit of the trousers.

[0051] like Figure 3-8 As shown, the sheet-type three-dimensional pants design method provided in this embodiment includes the following steps:

[0052] S1: Draw dividing lines on the trouser piece;

[0053] S2: Extract the cut pieces;

[0054] S3: Sewing trouser panels.

[0055] like Figure 3 As shown, in step S1, when drawing dividing lines on the trouser piece, the specific steps include: drawing the first dividing line 9, drawing the second dividing line 10, and drawing the third dividing line 11.

[0056] When drawing the first dividing line 9, the intersection of the first trouser center line 4 and the knee circumference line 8 is A. The first dividing line 9 is drawn from point A to the edge above the hip circumference line 6 of the back piece 2.

[0057] When drawing the second dividing line 10, the intersection of the second trouser center line 5 and the knee circumference line 8 is B. The second dividing line 10 is drawn from point B to the edge below the knee circumference line 8 of the back piece 2.

[0058] When drawing the third dividing line 11, the third dividing line 11 is drawn from point B to the edge between the horizontal crotch line 7 and the hip line 6 of the back piece 2.

[0059] like Figure 4 As shown, in step S2, when extracting the cut pieces, the specific steps include:

[0060] Extract the first piece 12: Cut the first piece 12 by cutting the front piece 1 and the back piece 2 along the first dividing line 9 and the knee circumference line 8;

[0061] Extract the second piece 13: cut the back piece 2 along the second dividing line 10 and the third dividing line 11 and cut the second piece 13 down;

[0062] Extract the third piece 14: Cut the back piece 2 along the knee circumference line 8 to cut off the third piece 14;

[0063] like Figure 5 , Figure 6 As shown, in step S3, when sewing the trouser pieces, the specific steps include:

[0064] The first piece 12 is rotated around point C: the first piece 12 is rotated by an angle α (15°) outward from point C towards the front piece 1. The specific rotation angle is selected according to different pants sizes, so that the end point of the first piece 12 is raised by 2cm after rotation; point C is the outer end point of the knee line 8 on the front piece 1. Alternatively, as an alternative implementation, the end point of the first piece 12 is raised by 1.5-3cm after rotation. Also, as an alternative implementation, the angle α is 5-20°.

[0065] The second piece 13 is rotated around point D: the third piece 14 is rotated by an angle β (15°) outward from point D towards the back piece 2. The specific rotation angle is selected according to different pants sizes, so that the endpoint of the second piece 13 is raised by 2cm after rotation. Point D is the intersection of the center line 3 and the knee line 8. Alternatively, the endpoint of the second piece 13 is raised by 1.5-3cm after rotation. Another alternative implementation is an angle β of 5-20°.

[0066] like Figure 7 As shown, the triangular space 19 created by the rotation of the first piece 12 and the third piece 14 is mended. The specific steps are as follows: Due to the rotation of the first piece 12 and the third piece 14, a triangular space 19 is formed between the first piece 12, the third piece 14, and the knee circumference line 8. This triangular space 19 between the first piece 12 and the third piece 14 is filled in, creating a raised portion at the filled position to facilitate knee movement. Then, the first dividing line 9 between the first piece 12 and the third piece 14 is sewn together; the overlapping portion between the third piece 14 and the back piece 2 is cut off.

[0067] like Figure 8As shown, the second piece 13 is trimmed. The specific steps are as follows: After cutting the second piece 13 to the appropriate size, the third piece 14 is rotated, and the side length of the angle between it and the knee circumference line 8 of the back piece 2 is γ. A triangle with a side length equal to γ ​​is cut at the lower end of the third dividing line 11 of the second piece 13. The vertex of the triangle is located on the side away from the front piece 1, between the third piece 14 and the knee circumference line 8, and the other two points of the triangle are located at the two ends of the side length γ. Then, it is sewn back to its original position along the second dividing line 10 and the third dividing line 11, thereby forming a recessed portion at point B located in the popliteal fossa.

[0068] By setting the first dividing line 9, the second dividing line 10, and the third dividing line 11, after cutting the first piece 12, the second piece 13, and the third piece 14, the first piece 12 and the third piece 14 are rotated to form protruding and recessed parts. The protruding part is located above the knee line 8 of the front piece 1, and the recessed part is located at the knee line 8 of the back piece 2, which makes the pants have a better three-dimensional effect. The protruding and recessed parts are used to adapt to the needs of human movement, ensuring the consistency of the three-dimensional effect and better comfort when wearing.

[0069] like Figure 2 , Figure 5 As shown, in this embodiment, the back piece 2 is tapered at the waist. Specifically, a first cutting seam 16 extending downwards is provided along the upper edge of the trouser piece. The first cutting seam 16 is located on the center line 3 of the trousers, that is, the first cutting seam 16 extends from the waistband to the position where it intersects with the first dividing line 9. When sewing the trouser piece, the first cutting seam 16 is sewn together. The first cutting seam 16 has a certain width, and after sewing the first cutting seam 16, the trouser piece has a certain waist-tapering effect at the waist, making the three-dimensional shape just right when worn. Alternatively, as an alternative implementation, the first cutting seam 16 can be omitted, and the trousers can still be sewn; in this case, the trousers are straight and there is no waist-tapering effect.

[0070] like Figure 2 , Figure 5 As shown, in this embodiment, the trousers are further tapered at the waist. A second cutting seam 17 extending downwards is located along the upper edge of the trousers. The second cutting seam 17 is positioned on the back piece 2 near the second center line 5 of the trousers. The second cutting seam 17 connects to the second dividing line 10. When sewing the trousers, the second cutting seam 17 is sewn together. This second cutting seam on the back piece 2 creates a tapered waist effect, resulting in a better overall three-dimensional appearance. Alternatively, as an alternative implementation, the second cutting seam 17 can be omitted, and the trousers can still be sewn; in this case, the trousers are straight and do not have a tapered waist effect.

[0071] like Figure 3As shown, in this embodiment, when drawing the dividing lines on the trouser piece, it also includes drawing a fourth dividing line 18 and cutting out a fourth piece 15:

[0072] The specific steps are as follows: When drawing the fourth dividing line 18, the intersection of the middle pant center line 3 and the hip line 6 is E. The starting point of the fourth dividing line 18 is located at the upper edge of the front piece 1. Specifically, the starting point is set between the first pant center line 4 and the middle pant center line 3. The ending point of the fourth dividing line 18 is located at the pocket position of the pant piece. In addition, the fourth dividing line 18 extends to intersect with the second dividing line 10 after passing through point E.

[0073] When cutting the trouser pieces, the first piece 12 is cut along the fourth dividing line 18 to extract the fourth piece 15;

[0074] When sewing the trousers, after cutting the fourth piece 15 to the appropriate size, specifically, the first cutting seam 16 and the second cutting seam 17 on the fourth piece 15 need to be sewn together. Then, the fourth piece 15 is sewn back to its original position along the fourth dividing line 18 and the first dividing line 9. At this time, the first cutting seam 16 and the second cutting seam 17 are located on the fourth piece 15. After removing the fourth piece 15, it can be sewn separately. While sewing the fourth piece 15, the third piece 14 and the first piece 12 can be made, which can speed up the overall trouser production process. Alternatively, as an alternative implementation, the fourth piece 15 can be left uncut, and the first cutting seam 16 and the second cutting seam 17 can be sewn directly onto the first piece 12.

[0075] like Figure 3 As shown, in this embodiment, the fourth dividing line 18 is a straight line. Cutting the fourth dividing line 18 along the straight line minimizes the deformation after sewing the first cutting seam 16 and the second cutting seam 17, thus ensuring the waist-cinching effect of the first cutting seam 16 and the second cutting seam 17. Alternatively, as an alternative implementation, the fourth dividing line 18 can be set as an arc, which can also achieve the waist-cinching effect of the first cutting seam 16 and the second cutting seam 17.

[0076] like Figure 3 As shown, in this embodiment, the first dividing line 9 is an arc protruding towards the front piece 1. The arc makes the overall lines and pant shape softer and more beautiful. Alternatively, as an alternative implementation, the first dividing line 9 can also be a straight line, which can also achieve the sewing of the pants.

[0077] like Figure 3As shown, in this embodiment, the second dividing line 10 is a straight line, which facilitates cutting and speeds up the cutting of the second piece 13. Alternatively, as an alternative implementation, the second dividing line 10 can be arc-shaped, which also enables the cutting of the second piece 13.

[0078] like Figure 3 As shown, in this embodiment, the third dividing line 11 is an arc protruding towards the front piece 1. This allows for a softer line after cutting and sewing, resulting in a more aesthetically pleasing overall appearance. Alternatively, as an alternative implementation, the third dividing line 11 can also be a straight line.

[0079] like Figure 6 As shown, in this embodiment, the α angle and the β angle are the same, that is, after the second piece 13 and the third piece 14 are rotated, they form an approximately isosceles triangle with the knee circumference line 8. At this time, the protrusion effect is more obvious and more suitable for the movement of the human body, which conforms to the aesthetics of the pants. In addition, as an alternative implementation, the α angle and the β angle can also be set differently, only requiring the gap after the first piece 12 and the second piece 13 are rotated to be filled.

[0080] like Figure 6 As shown, in this embodiment, the α angle and the β angle are 15°. At this point, the endpoint of the second piece 13 moves upward by 2cm after rotation, creating a convex effect that is suitable for human movement. Alternatively, as an alternative implementation, the α angle and β angle can be set to other values, such as 5°, 10°, etc.

[0081] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
