[001] This disclosure claims priority over Chinese patent application number 2024100162245, entitled “Soccer ball and training component”, filed with the Chinese Patent Office on January 4, 2024, and U.S. patent application number US18 / 829400, entitled “SOCCER BALL AND SOCCER TRAINING ASSEMBLY”, filed with the U.S. Patent Office on September 10, 2024. TECHNICAL AREA

[002] This disclosure relates to the field of sports equipment technology, specifically a soccer ball and training component. BACKGROUND TECHNOLOGY

[003] In the sport of football, plays represent an important and advanced skill, including free kicks, penalty kicks, corner kicks, goal kicks, etc. In each of the kicking actions, there are rigorous and different requirements for objective technical elements such as placement, run-up, landing, supporting foot, and kick tracking. People need to undergo extensive testing to understand the impact of objective technical elements on the effect of the strike and then practice extensively to form action habits and muscle memory in order to shape their movements and master specific types of set-piece skills. However, in related technologies, there is a lack of training equipment for training set-pieces that can systematically, accurately, rigorously, and efficiently pinpoint specific technical elements such as angles, distances, positions, directions, etc.In each link of the movement, it is difficult for people to maintain the highest precision and stability during training to accurately test and repeat movements correctly, resulting in low efficiency and poor results. CONTENT OF THE INVENTION Petition 870260061403, dated 06 / 23 / 2026, page 6 / 207 2 / 49

[004] This disclosure provides a soccer ball, training component and training device that can improve the efficiency and effectiveness of set-piece training.

[005] The disclosed implementation methods can be implemented as follows:

[006] The disclosed embodiments provide a soccer ball, which has a sphere and a defined marking area on the surface of the sphere. The marking area includes the initial aiming guide line, the ball placement line and the striking point set.The initial aiming guide line, the ball placement line, is located in different sections, with each section being a sectional plane that passes through the center of the sphere. The set of hit points includes multiple distributions of hit reference point intervals. The distribution paths of multiple hit reference points coincide with the cross-section of the initial aiming guide line, defining the horizontal midline section as a sectional plane that passes through the center of the sphere. When the cross-section of the initial aiming guide line and the cross-section of the swing line are both perpendicular to the ground, the ball placement line section is parallel to the ground, with multiple hit reference points distributed downwards from the horizontal midline section.

[007] In the example above, the initial aiming guide line, ball placement line, and batting reference point, distribution paths, etc. The circular line formed by the intersection of is a sectional plane that passes through the center of the sphere and the surface of the sphere, when the user rotates relative to the sphere, visually overlaps these marking area lines and appears as a straight line. According to the angular relationship between the initial aiming guide line and the ball placement line relative to the ground, after the sphere is rotated in place by the user, when the cross-section of the initial aiming guide line is perpendicular to the ground, the initial aiming guide line is presented to the user as being “hanging” from the ground in the user's view. Petition 870260061403, dated 06 / 23 / 2026, p. 7 / 207 3 / 49 user; When the section where the ball placement line is presented as being “perpendicular” to the ground, the ball placement line is presented as being “perpendicular” to the ground. And when the user is facing the initial aiming guide line that is “perpendicular” to the ground, the initial aiming guide line seen by the user can be used to indicate the direction, being presented as a “straight line”. Therefore, by placing the sphere so that the cross-sections of the initial aiming guide line and the ball placement line are perpendicular to the ground and aligning the initial aiming guide line with the predefined target direction, the position of the marking area on the sphere in relation to the ground can be determined, completing the “correct ball placement” and improving ball placement efficiency, thus increasing training efficiency.Several striking reference points are located in the section where the initial aiming guide line is located. By aligning the “straight line” presented by the initial aiming guide line with the direction of the predefined target, it can be used to guide the direction of flight of the ball when the user strikes the ball through the striking reference point. After “correct ball placement,” with each striking reference point distributed downwards from the horizontal centerline section, users kick the ball into the positions indicated by each striking reference point, causing the ball to fly in the direction indicated by the initial aiming guide line. The further away from the horizontal centerline section, i.e., the lower the striking reference point, the greater the angle of flight of the ball. This allows the ball to fly in the desired direction.To practice at the angle corresponding to the ball's height, kick the ball towards the corresponding batting reference point. When using the soccer ball shown for set-piece training, the user can quickly straighten the ball and aim it at the batting target using the initial aiming guide line and the ball placement line, thus completing the "correct ball placement". This ensures that the positions of each batting reference point in relation to the ground, the ball, and the predetermined batting target are correct. Petition 870260061403, dated 06 / 23 / 2026, p. 8 / 207 4 / 49 fixed. After the correct run-up and shot, the direction of flight and trajectory of the ball will also be the same and fixed. The user can assess whether they have accurately and effectively hit the desired point of contact with the ball in all their shooting actions, based on the effect of their own shot, in order to improve and refine various elements of the action, such as the angle and running path, the supporting foot on landing, the shooting posture, the ball tracking movements, etc. After becoming familiar with the effective actions, they can form action habits and muscle memory, so that even when using a soccer ball without a designated area to kick the ball, they can apply the familiar details of the actions and consistently achieve the specific effect of the shot during training.Therefore, using soccer ball drills with the marking area mentioned above, it is possible to improve the efficiency and effectiveness of goal kick practice training through the use of a soccer ball.

[008] Optionally, the central axis is defined as the intersection line between the cross-section of the initial aiming guide line and the cross-section of the ball placement line. The marking area also includes the ball approach angle point guide mark, the ball approach angle guide mark includes several ball approach angle points of the ball approach angle guide mark. The different ball approach angle points and central axis intersect with the cross-section of the initial aiming guide line.

[009] In the example above, when a user kicks a stationary ball, running from different directions relative to the soccer ball can affect factors such as the direction of the force exerted by the user's foot when kicking the ball. The section where each point of approach angle of the ball and center axis is located forms an angle with the section where the initial aiming guide line is located, which can be used to indicate the user's running angle. After "correct ball placement," when the user positions themselves on the positive side of the section where the point of approach angle of the ball and the axis Petition 870260061403, dated 06 / 23 / 2026, p. 9 / 207 Located at the 5 / 49 center, the initial aiming guide line can be visually presented as a "straight line," which can be used to indicate the user's running angle relative to the direction of the ball, making it easier for the user and helping to improve the efficiency and effect of the training.

[010] Optionally, the ball approach guide mark also includes multiple ball approach guide lines, each ball approach angle point defined on a ball approach guide line, when the cross-section of the initial aiming guide line and the cross-section of the swing line are both perpendicular to the ground ball placement line each ball approach guide line is perpendicular to the ground.

[011] In the example above, the section where the ball approach guide line is located is the section where the ball approach angle point and the central axis are located, after “correct ball placement”. When the user positions themselves on the side of the section of the ball approach guide line corresponding to the running angle to be practiced, the ball approach guide line in the user's view will be displayed as a “straight line”. This can be used to indicate direction and improve the user's recognition of the running direction, which is beneficial for increasing the efficiency and effectiveness of the user's training in practicing running direction.

[012] Optionally, the central axis is defined as the intersection of the cross-section where the initial aiming guide line is located and the cross-section where the ball placement line is located. The marking area also includes tracking guide marks; tracking guide marks include multiple tracking angle points and multiple tracking guide lines. The angle between the cross-section where different tracking angle points and the central axis are located and the cross-section where the initial aiming guide line is located is different for each tracking angle point located on a tracking guide line; when the cross-section of the initial aiming guide line and the cross-section of the line of Petition 870260061403, dated 06 / 23 / 2026, p. 10 / 207 6 / 49 balance are both perpendicular to the ground ball placement line with each section of the follow-line perpendicular to the ground.

[013] In the example above, when the user kicks a stationary ball, tracking from different directions relative to the soccer ball can affect factors such as the direction of the force exerted by the user's foot during the kick. The section where the Tracking Guideline is located is the section where the tracking angle point and the center axis are located, after “correct ball placement”. When the user positions themselves on the positive side of the section where the Tracking Guideline corresponding to the tracking angle to be practiced is located, the Tracking Guideline in the user's vision will appear as a straight line, which can be used to indicate the direction and improve the user's recognition of the tracking direction, which is conducive to improving the efficiency and effectiveness of the user's lateral tracking training.

[014] Optionally, the Hit Point Set also includes a first lateral rotation point, the first lateral rotation point is distributed at intervals with one of the multiple hit reference points in a direction perpendicular to the cross-section where the initial sight guide line is located.

[015] In the example above, the player applies a side effect by applying a lateral force that passes through the center of the ball to the side of the target's impact position when kicking a stationary ball. After "correct ball placement," taking the section of the horizontal midline as the position of the "equator" of a sphere, then the first lateral pivot point and the corresponding rebound reference point are located at similar "latitude" positions, so after "correct ball placement," the first lateral pivot point is located next to the corresponding rebound reference point, and the user can kick towards the first lateral pivot point to kick the ball that corresponds to the rebound reference point. The side effect of the ball rebounded in the same direction of exit allows the user to create the side effect. Petition 870260061403, dated 06 / 23 / 2026, p. 11 / 207 7 / 49 helping to improve the efficiency and effect of training.

[016] Optionally, the Hit Point Set also includes an upward rotation point, which is located away from the hit reference point and situated in the cross-section where multiple hit reference points meet. When the cross-section of the initial aiming guide line and the cross-section of the balance line are both perpendicular to the ground ball placement line, the upward rotation point is located on the lower side of one of the multiple hit reference points.

[017] In the example above, when kicking a stationary ball, the user applies a force that passes over the center of the ball below the batting position at target height, thus kicking an upward rotation point. After correct ball placement, the upward rotation point is located below the corresponding batting reference point, and the user can kick the upward rotation point in the same direction as the corresponding batting reference point when kicking the ball towards the upward rotation point, allowing the user to improve the efficiency and effect of the training.

[018] Optionally, the Hit Point Set also includes a second lateral rotation point, the second lateral rotation point is distributed at intervals from the upward rotation point in the direction perpendicular to the cross-section where the initial aiming guide line is located.

[019] In the example above, the user imparts a side effect by applying a lateral force that passes through the center of the ball to the side of the target's hit position when kicking a stationary ball. After "correct ball placement," where the section of the horizontal midline is considered the 'equatorial' position of a sphere, and the second point of lateral rotation is located at a 'latitude' position similar to the upward rotation point, then after "correct ball placement," and the second point of lateral rotation is located on the side of the upward rotation point. If the user kicks the ball towards the second point of lateral rotation, they can impart a side effect. Petition 870260061403, dated 06 / 23 / 2026, page 12 / 207 8 / 49 ascending on the side of the upward rotation point. Thus, it can allow the user to rotate the ball on the opposite side, helping to improve the efficiency and effect of the training.

[020] Optionally, the marking area also includes an assistance guide mark, the assistance guide mark includes an assistance batting line and an assistance batting reference point. The assistance batting reference point is located at the intersection of the assistance batting line and the horizontal centerline section, with a blank area being a completely blank area near the assistance batting line; when the section where the initial aiming guide line is located and the section where the ball placement line is located are both perpendicular to the ground, the section where the assistance batting line is located is perpendicular to the ground.

[021] In the example above, after “correct ball placement”, the assist batting line in the cross-section is also perpendicular to the ground, and the assist batting line can also be the line displayed as a “straight line” in the user’s view to guide the direction of the target batting. using the assist batting line and the assist batting line with the position of the intersection point of the horizontal midline section, i.e., the assist batting reference point, the user can, as needed, draw points or lines in the nearby area as new batting points, to test new batting effects.

[022] By creating a complete blank area to facilitate coloring with an oil-based marker, the user can add auxiliary markers, such as Batting Point Set, Ball Approach Guide Mark, or Tracking Guide Mark, to test various effects within the complete blank area, which helps improve training effectiveness.

[023] Optionally, define the center axis as the intersection line between the section where the initial aiming guide line is located and the section where the ball placement line is located. The marking area also includes the first and second placement points, which are located at both Petition 870260061403, dated 06 / 23 / 2026, p. 13 / 207 9 / 49 ends of the central axis.

[024] In the example above, after “correct ball placement”, one of the first and second placement points should be located at the top of the sphere and the other should be located at the bottom of the sphere. The user can use the relative position on the ground of the first and second placement points to help adjust the placement posture of the sphere, thus improving the accuracy and efficiency of the placement. It can allow left- and right-handed players to use most of the original markings on the sphere together (except the Penalty Kick Strike Point / Guide Mark), and lead to an improvement in training efficiency.

[025] Optionally, the marking area can be sprayed onto the sphere with paint, glued onto the sphere with stickers, or printed onto the sphere.

[026] In the example above, pigment spraying, sticker application and printing methods can improve the speed and accuracy of marking area definition on the sphere and increase the efficiency of soccer ball production.

[027] The disclosed embodiments also provide a training component, which includes a Support Foot marker, as described above. The Support Foot marker includes a lateral positioning segment, a first marking portion, and a second marking portion. The lateral positioning segment is perpendicular to the cross-section where the initial aiming guide line is located when in use. The second marking portion is located at the end of the lateral positioning segment, while the first marking portion is located above the lateral positioning segment and can move freely within the lateral positioning segment to adjust the distance between the first marking portion and the second marking portion, which is used to guide the user's predefined landing point of the support foot on the ground, forming the positional relationship between the support foot and the soccer ball.

[028] In the example above, first, place the supporting foot marker on a Petition 870260061403, dated 06 / 23 / 2026, p. 14 / 207 10 / 49 approximate position next to the penalty mark on the ground, ensuring that the side positioning segment is perpendicular to the starting line and remains so thereafter. After correctly placing the ball, by moving the soccer ball to the left or right, set the distance between the section where the initial aiming guide line is located and the second marking portion to the length of the sphere's radius and maintain it from there. Then, by sliding the first marking portion on the side positioning segment, adjust the horizontal direction of the first marking portion relative to the section where the initial aiming guide line is located and the second marking portion. Distance. Finally, by moving the soccer ball forward or backward on the section where the initial aiming guide line is located, it is possible to determine the position of the side positioning segment relative to the striking point assembly on the ground.This will adjust the positional relationship between the landing point of the supporting foot and the actual strike point, and will provide guidance for the user's "correct positioning" of the supporting foot, facilitating repeated practice of supporting foot positioning and improving training effectiveness.

[029] Optionally, the Foot Support marker includes a length reference segment and a lateral positioning segment, the length reference segment is attached to the lateral positioning segment and is attached at the position of the second marking portion, and the length of the length reference segment is used as a size reference to adjust the distance between the first marking portion and the second marking portion; The lateral positioning segment is made of flexible cord material.

[030] In the example above, bend the length reference segment to be parallel and overlap the side positioning segment and slide the first marking portion to adjust its position, referencing the length of the length reference segment. This allows you to quickly adjust the position of the first marking portion relative to the second. Petition 870260061403, dated 06 / 23 / 2026, page 15 / 207 11 / 49 marking portion or to the actual impact point, and lead to an improvement in training efficiency.

[031] By limiting the material used to manufacture the lateral positioning segment, it is ensured that the lateral positioning segment is not easily crushed by the boots during use, thus helping to extend the lifespan of the lateral positioning segment and ensure the effectiveness of the training.

[032] Optionally, the penalty area also includes the penalty guide mark, the penalty guide mark includes the first point of the penalty angle, the second point of the penalty angle, the third point of the penalty angle and the fourth point of the penalty angle, respectively used to instruct the user to aim at the four corners of the goal when taking a penalty, and sequentially connect the first point of the penalty angle. The area formed by the penalty point, the second point of the penalty angle, the fourth point of the penalty angle and the third point of the penalty angle is the range that indicates the point of impact within the goal area when the user takes a penalty.

[033] In the example above, a practice play includes a penalty kick taken from the penalty spot in front of the goal. The first point of the penalty kick angle, the second point of the penalty kick angle, the third point of the penalty kick angle, and the fourth point of the penalty kick angle can correspond to the four corners of the goal in relation to the center of the ball, so that the user can kick towards the corner of the goal during a penalty kick, helping to improve the efficiency and effect of the training.

[034] After connecting the first point of the penalty kick angle, the second point of the penalty kick angle, the fourth point of the penalty kick angle, and the third point of the penalty kick angle, the area within reach of the four points corresponds to the reach of the goal, allowing the Petition 870260061403, dated 06 / 23 / 2026, page 16 / 207 12 / 49 users kick towards a position within reach of the goal when taking a penalty, helping to improve the efficiency and effectiveness of the training.

[035] Compared to existing technologies, the beneficial effects of this disclosed implementation method include, for example:

[036] The soccer ball and training components can serve as a guide for users, allowing them to use the disclosed soccer ball for training set plays. Through the initial aiming guide line and the ball placement line, they can quickly straighten the ball and aim at the target, completing the correct ball placement quickly. This ensures that the positions of each striking reference point in relation to the ground, the ball, and the predefined target are correctly fixed. After a proper run-up and shot, the flight direction and trajectory of the ball will also be the same and fixed. The user can determine whether they have accurately and effectively hit the desired striking point on the ball based on their own shooting effect after shooting the ball, in order to further improve and finalize the various elements of the action, such as running angle and trajectory, landing of the supporting foot, shooting posture, follow-up action, etc.After becoming familiar with effective actions, they can form action habits and muscle memory, so that even when using a soccer ball without a designated area to kick the ball, they can apply the familiar details of the actions and consistently achieve the specific kicking effect during training. Therefore, using the soccer ball exercises with the designated area mentioned above, it is possible to improve the efficiency and effectiveness of training when practicing a goal kick using a soccer ball.

[063] Furthermore, the use of terms such as “horizontal”, “vertical”, “projecting” does not necessarily mean that the component must be absolutely horizontal or projecting, but may be slightly inclined. “Horizontal” refers only to its direction being more horizontal in relation to “vertical” and does not necessarily mean that the structure must be completely horizontal, but may be slightly inclined.

[064] In this disclosure, it should be noted that, unless otherwise indicated and limited in Petition 870260061403, dated 06 / 23 / 2026, page 20 / 207 16 / 49 Conversely, the terms “configuration”, “installation”, “connection”, “link”, etc. should be understood broadly, for example, they may be fixed connections, detachable connections or integrated connections; it may be a mechanical connection or an electrical connection; it may be connected directly, connected indirectly through an intermediate medium or connected internally between two components. For ordinary technical personnel in this area, the specific meanings of the above terms in this disclosure may be understood in specific situations.

[065] It should be noted that the features in the disclosed embodiments can be combined with each other without conflict. The disclosed embodiments provide a soccer ball, a training component, and a training device. The soccer ball has a sphere and a marking area located on the surface of the sphere. The marking area includes the initial aiming guide line, the ball placement line, and the batting point assembly, each located on the surface of the sphere. The initial aiming guide line and the ball placement line are located in different cross-sections. Each section has a sectional plane that passes through the center of the sphere. The batting point assembly includes multiple batting reference point interval distributions. The cross-section where the multiple batting reference point distribution paths coincide with the cross-section where the initial aiming guide line is located.The horizontal midline section is defined as a sectional plane that passes through the center of the sphere. When the cross-section of the initial aiming guide line and the cross-section of the swing line are both perpendicular to the ground (ball placement line), the horizontal midline section is parallel to the ground, with multiple hit reference points distributed downwards from the horizontal midline section.

[066] In mathematical definition, the spatial geometry formed by a semicircle rotating once around a straight line with its diameter is called a sphere. A sphere is a solid shape of a continuous surface, Petition 870260061403, dated 06 / 23 / 2026, p. 21 / 207 17 / 49 and the geometry bounded by a sphere is called a sphere. The soccer ball in this advertisement belongs to the sphere described in this definition.

[067] All points on the sphere are calculated and located using tools such as “spherical coordinate system”, “latitude and longitude coordinate system”, “arc length”, etc.

[068] The distribution paths of the initial aiming guide line, the ball placement line, the ball approach guide line, and the batting reference point are the circular lines formed by the intersection of the cross-section is a sectional plane that passes through the center of the sphere. When the user and the sphere rotate relative to each other and position themselves on the positive side of these cross-sections (i.e., one eye is in front of the cross-section, the other eye is behind the interface, and the nose passes through the cross-section), the lines of the relevant cross-sections in the marking area may visually overlap and appear as a certain straight line.According to the angular relationship between the initial aiming guide line and the ball placement line relative to the ground, after the ball is rotated in place by the user, when the cross-section of the initial aiming guide line is presented as being “perpendicular” to the ground, the initial aiming guide line is presented to the user as being “hanging” from the ground in the user's view; when the section where the ball placement line is presented as being “perpendicular” to the ground is presented as being “perpendicular” to the ground in the user's view, the ball placement line is presented to the user as being “hanging” from the ground. And when the user is on the positive side of the section where the initial aiming guide line is “perpendicular” to the ground, the initial aiming guide line seen by the user can be used to indicate direction.Therefore, by positioning the sphere so that the cross-sections of the initial aiming guide line and the ball placement line are perpendicular to the ground, and aligning the initial aiming guide line with the direction of the predetermined target, the position of the marking area on the sphere in relation to the ground and the ball target can be located, completing the "correct placement." Petition 870260061403, dated 06 / 23 / 2026, page 22 / 207 18 / 49 of the ball” and improving the efficiency of ball placement and training. Several hit reference points are located in the section where the initial aiming guide line is located. Presented as a “straight line” by the initial aiming guide line with the direction of the predefined target, it can be used to guide the direction of flight of the sphere when the user hits the ball through the hit reference point. After correct ball placement, with each hit reference point distributed downwards from the horizontal midline section. Users kick the ball in the positions indicated by each hit reference point, causing the ball to fly in the direction indicated by the initial aiming guide line.To practice at the angle corresponding to the ball's height, kick the ball towards the corresponding batting reference point. When using the soccer ball released for set-piece training, the user can quickly straighten the ball and aim it at the batting target via the initial aiming guide line and the ball placement line, completing the "correct ball placement" quickly. This ensures that the positions of each batting reference point relative to the ground, the ball, and the predetermined batting target are correctly fixed. After the correct run-up and kick, the flight direction and trajectory of the ball will also be the same and fixed.The user can assess whether they have accurately and effectively hit the designated striking point on the desired sphere based on their own striking effect after hitting the ball, in order to adjust and shape the various elements of the action, such as the angle and trajectory of the run-up, the landing position of the supporting foot, the striking posture, and subsequent movements. After effectively testing and familiarizing themselves with the action, they can form action habits and muscle memory, so that when using the soccer ball without a marking area to kick the ball, they can also apply the details and techniques of the actions they have mastered proficiently and consistently achieve the specific striking effect. Petition 870260061403, dated 06 / 23 / 2026, page 23 / 207 19 / 49 during training. Therefore, using soccer ball drills with the marking area mentioned above can improve training efficiency and the striking effect of set plays.

[069] When the soccer ball is correctly placed across the ball placement line, all other identifying elements on the sphere can also be accurately positioned for training purposes. Otherwise, their positions will all be off and incorrect, or even fail. Therefore, the ball placement line is one of the key elements when using this soccer ball.

[070] A detailed explanation of the embodiments disclosed in conjunction with the attached drawings will be provided below. In non-conflicting situations, the following implementation methods and their characteristics may be combined with each other.

[071] Referring to Figure 1, the disclosed embodiment provides a soccer ball 100 for use by user 1000 (as shown in Figure 6) in practicing set plays. User 1000 practices a set play using the disclosed soccer ball 100 to control the flight trajectory of sphere 1 when kicking a set play. Optionally, sphere 1 includes an inner liner (not shown) and an outer liner that surrounds the inner liner, both spherical in shape and with overlapping centers.

[072] Referring to Figures 1 and 2, alternatively, the football 100 has a sphere 1 and a marking area 2 located on the surface of sphere 1. The marking area 2 includes the initial aiming guide line 21, the ball placement line 22 and the striking point assembly 24, each located on the surface of sphere 1. Understandably, optionally, the marking area 2 is located on the surface of the outer skin.

[073] The football 100 has a sphere 1 and a marking area 2 located on the surface of sphere 1. The marking area 2 includes the initial aiming guide line 21, the ball placement line 22 and the striking point set 24, each located on the surface of sphere 1. Petition 870260061403, dated 06 / 23 / 2026, page 24 / 207 20 / 49

[074] The initial aiming guide line 21 and the ball placement line 22 are located in different cross-sections. Each section has a sectional plane that passes through the center of the sphere 1. The hit point set 24 includes multiple hit reference point interval distributions 241. The cross-section where the multiple hit reference point distribution paths 241 are located coincides with the cross-section where the initial aiming guide line 21 is located. Define horizontal midline section 231 as a sectional plane that passes through the center of the sphere 1. Define center axis 232 as the intersection of the section where the initial aiming guide line 21 is located and the section where the ball placement line 22 is located.

[075] When the cross-sections of the initial aiming guide line 21 and the ball placement line 22 are both perpendicular to the ground, the horizontal median line section 231 is parallel to the ground, the central axis 232 is perpendicular to the ground and several hit reference points 241 are distributed downwards from the horizontal median line section 231.

[076] The distribution paths of the initial aiming guide line 21, the ball placement line 22 and the hit reference point 241 are all circular lines formed by the intersection of a sectional plane that passes through the center of sphere 1 and sphere 1. After the user 1000 rotates relative to sphere 1, these marking area lines 2 may visually overlap and appear as a straight line.According to the angular relationship between the initial aiming guide line 21 and the ball placement line 22 in relation to the ground, after adjusting the contact point of sphere 1 on the ground by rotating sphere 1 in place using user 1000, when the cross-section of the initial aiming guide line 21 is perpendicular to the ground, the initial aiming guide line 21 in the view of user 1000 can be displayed as being “perpendicular” to the ground; when the cross-section of the ball placement line 22 is perpendicular to the ground, the ball placement line 22 in the view of user 1000 can be displayed as being “perpendicular” to the ground. And when the user... Petition 870260061403, dated 06 / 23 / 2026, p. 25 / 207 21 / 49 1000 is on the positive side of the section where the initial aiming guide line 21 is located, the initial aiming guide line 21. In the user's view 1000 can be used to indicate direction. Several hit reference points 241 are located in the section where the initial aiming guide line 21 is located. Presented as a “straight line” by the initial aiming guide line 21 with the predefined target direction, it can be used to guide the flight direction of sphere 1 when the user 1000 hits the ball through hit reference point 241.

[077] Therefore, by placing sphere 1 so that the cross-sections of the initial aiming guide line 21 and the ball placement line 22 are perpendicular to the ground, and aligning the initial aiming guide line 21 with the predetermined target direction, it is possible to locate the position of the marking area 2 on sphere 1 in relation to the ground, completing the correct ball placement and improving the efficiency of the ball swing, thus increasing the efficiency of the training. Therefore, the steps referred to in “correct ball placement” are: 1. Make the initial aiming guide line 21 “perpendicular” to the ground; 2. Make the ball placement line 22 “perpendicular” to the ground; 3. Rotate the soccer ball in place and align the initial aiming guide line 21 with the direction of the predefined batting target.

[078] After “correct ball placement”, where each batting reference point 241 is distributed downwards from the horizontal midline section 231. User 1000 kicks the ball into the position indicated by each batting reference point 241, causing the ball 1 to fly in the direction indicated by the initial aiming guide line 21, while simultaneously kicking towards the batting reference point 241 furthest from the horizontal midline section 231, i.e., towards the lowest batting reference point 241. The greater the exit angle (the angle between the exit line and the ground), the further you can kick the ball towards the corresponding batting reference point 241, according to the angle needed to practice ball height. Petition 870260061403, dated 06 / 23 / 2026, p. 26 / 207 22 / 49

[079] When using the football 100 disclosed for training set plays, the user 1000 can quickly straighten the ball and aim it at the striking target via the initial aiming guide line 21 and the ball placement line 22, completing the correct ball placement. This ensures that the positions of each striking reference point 241 in relation to the ground, sphere 1 and the predefined striking target are correctly fixed. After the correct run-up and strike, the flight direction and trajectory of sphere 1 will also be the same and fixed. The user 1000 can determine whether they accurately and effectively hit the desired striking point on sphere 1 based on their own striking effect after hitting the ball, in order to further improve and finalize various elements of the action, such as the angle and running path, the landing of the supporting foot 1002, the striking posture, the ball tracking movements, etc.After becoming familiar with effective actions, you can form action habits and muscle memory, so that even when using a 100-ball without a marking area to kick the ball, you can apply the familiar details and techniques of the movements to consistently achieve the specific striking effect during training. Therefore, using the 100-ball exercise with the marking area mentioned above, it is possible to improve the efficiency and effectiveness of training when practicing a goal kick using a soccer ball.

[080] Referring to Figures 1 and 2, alternatively, the angle between the two ends of the initial sighting guide line 21 and the center of sphere 1 is 90°. The angle between the two ends of the ball placement line 22 and the center of sphere 1 is 90 degrees. One end of the initial sighting guide line 21 is connected to one end of the ball placement line 22 and to one end of the central axis 232. The other end of the initial sighting guide line 21 and the other end of the ball placement line 22 are both located on the section of the horizontal centerline 231. Understandably, optionally, the section where the initial sighting guide line 21 is located and the section where the ball placement line 22 is located are located Petition 870260061403, dated 06 / 23 / 2026, p. 27 / 207 23 / 49 perpendicular to each other.

[081] Optionally, the initial aiming guide line 21 which is continuously extended, or a line that is not continuously extended, such as a dashed line, a dotted line and a double dotted line. ball placement line 22 which is continuously extended, or a line that is not continuously extended, such as a dashed line, a dotted line and a double dotted line, such as a dashed line, a dotted line and a double dotted line. The hit reference point 241 includes, but is not limited to, intersection points of two lines, circular points, elliptical points, triangular points, square points and polygonal points, which may be solid points or hollow points.

[082] Referring to Figures 1 and 5, alternatively, the angle between the centers of two adjacent hit reference points 241 with respect to sphere 1 represents the angle between the trajectories of sphere 1 when it touches the ball through these two hit reference points 241. As an exemplary example, hit reference point 241a located at the horizontal midline section 231 is used to practice ground set plays, hit reference point 241b is used to practice set plays with an elevation angle of 8.4°, and hit reference point 241c is used to practice flying set plays with an elevation angle α of 14.7°.When sphere 1 uses a standard size 5 ball with a circumference of 69 cm, the arc length between the hit reference point 241b and the hit reference point 241a is 1.61 cm, and the arc length between the hit reference point 241c and the hit reference point 241a is approximately 2.82 cm.

[083] Referring to Figure 7, in the disclosed embodiment, if the strict ball placement line 22 is missing as a reference, even if all other steps are correct, the horizontal centerline section 231 of the sphere cannot be truly parallel to the ground, and all the Hit Point Set 24 cannot be in their true correct positions. Petition 870260061403, dated 06 / 23 / 2026, p. 28 / 207 24 / 49 Without the ball placement line 22, the user can only rely on feel and estimation to swing the ball, inevitably resulting in errors in ball balance, causing deviations in the positions of all point / line elements on the sphere. Therefore, the ball placement line 22 is essential and has top priority.

[084] Specifically, taking as an example a shot into the top left corner of the goal from 18Y / 16.5 m outside the penalty area line, see Table 1 below:

[085] Table 1 Ball deviation value Distance of the impact point below the horizontal center line Ball angle The height of the soccer ball as it passes the goal Exceeding the height of the outer crossbar 0 1.53cm 8° 244cm 0 0.5cm 2.03cm 10.59° 316cm 72cm 1cm 2.53cm 13.2° 398cm 154cm

[086] Even if the cross-section where the initial aiming guide line 21 is located is correctly perpendicular to the direction of the ball and points perfectly correctly, i.e. there is no deviation in the left and right directions of the ball, if the first swing point 281 cannot be accurately placed in the top position, then, since the first swing point 281 is slightly forward or backward, this will cause a significant deviation in the angle of height of the ball (as shown in Table 1, if the first swing point deviates 1 cm backward, the football 100 will be 154 cm higher than the goalpost), a rigorous method must be used to ensure that the central axis 232 is perpendicular to the ground.

[087] It should be noted that there is a first oscillation point 281 and a Petition 870260061403, dated 06 / 23 / 2026, p. 29 / 207 25 / 49 second oscillation point 282 at the top and bottom of the central axis, respectively. However, when these two oscillation points are used alone, they cannot complete the oscillation. In visual theory, the human eye must be at the height of the center of the ball (approximately 11 cm above the ground, the point at which the head of the eye needs to be close to the ground) and, at the same time, the person needs to be at an infinite distance of 100 from the soccer ball to observe the two oscillation points simultaneously, which is obviously difficult to achieve on the court.

[088] Referring to Figure 7, in fact, due to the natural posture of the human body when observing the ball's balance, the height of the human eye in relation to the ground is between 1.5 m and 2 m (slightly lower than the height of the human body), and the standing position is usually a few meters from the soccer ball. At that moment, the vertex of the soccer ball can usually be seen, but the bottom point of the soccer ball is close to the grass (i.e., about 0 in relation to the height of the ground), and the eye position is high. When observing the bottom point, the field of vision will be blocked by the sphere, so it is impossible to directly observe the defined central axis, i.e., it cannot be used to help in the correct balance of the ball; The height of the horizontal center line of the soccer ball is about 11 cm, which appears as a circular arc in human vision, because it is not possible to directly determine if the horizontal center line is actually parallel to the ground.

[089] Therefore, you need to use the ball placement line 22 to solve this problem. The ball placement line 22 is the line formed by the intersection of the two ends of the central axis section (which can be formed by “three points and a face”) and the sphere. People can easily determine the accuracy of the soccer ball placement based on the fact that the ball placement line is perpendicular to the ground in a natural stance and can easily adjust the impact point to the correct position.

[090] When the football 100 is correctly placed across the ball placement line 22, all other elements (including identifiers) Petition 870260061403, dated 06 / 23 / 2026, p. 30 / 207 26 / 49 on the ball can also be positioned precisely for training purposes. Otherwise, their positions will all deviate and be incorrect, or even fail. Therefore, the ball placement line 22 is one of the key elements of this 100 soccer ball during training.

[091] Referring to Figures 1 and 2, optionally, marking area 2 also includes the ball approach guide mark 25. The ball approach guide mark 25 includes several ball approach angle points 251. The angle between the section where different ball approach angle points 251 and central axis 232 are located and the section where the initial aiming guide line 21 is located is different. The section where each ball approach angle point 251 and central axis 232 is located is called the “ball approach section”.

[092] It should be noted that every kicking action necessarily includes a run-up, and different kicking actions require different angles between the direction of the run-up and the direction of exit during the run-up, in order to achieve the necessary exit angle. Only the ball approach guide mark can correctly guide the angle of the run-up.

[093] When user 1000 kicks a stationary ball, running in different directions relative to the soccer ball 100 will affect the direction of the force exerted by the kicking foot 1001 when user 1000 kicks the ball. Each “ball approach section” forms an angle with the section where the initial aiming guide line 21 is located, which can be used to indicate user 1000’s run-up angle.After "correct ball placement," when User 1000 is on the positive side of the "ball approach section" (i.e., one eye is ahead of the section, the other eye is behind the section, and the nose passes through the section), the "ball approach section" can be visually represented as a "straight line," which can be used to indicate User 1000's running angle relative to the direction of the ball, making it easier for User 1000 to execute different running directions, helping to improve the efficiency and effect of the training. Petition 870260061403, dated 06 / 23 / 2026, p. 31 / 207 27 / 49

[094] Referring to Figures 1 and 2, alternatively, the ball approach guide mark 2 also includes multiple ball approach guide lines 252. Each ball approach angle point 251 is located on a ball approach guide line 252. When the cross-sections of the initial aiming guide line 21 and the ball placement line 22 are both perpendicular to the ground, each cross-section of the ball approach guide line 252 is perpendicular to the ground. The section where each ball approach guide line 252 is located is the corresponding “ball approach section” of the ball approach angle point 251.

[095] The section where the ball approach guide line 252 is located corresponds to the “ball approach section” where the ball approach angle point 251 and the central axis 232 are located, and after correct ball placement. When user 1000 positions himself directly in the “ball approach section” where the ball approach angle point 251 is located, the ball approach guide line 252 in the user 1000’s view can be presented as a “straight line” to indicate the angle between the running direction and the exit direction, user 1000 can improve the recognition of the running direction by user 1000 and increase the efficiency and effectiveness of the training.

[096] Referring to Figures 1 and 2, alternatively, several points of approach angle of the ball 251 can be defined on the horizontal median line section 231. Several points of approach angle of the ball 251 can be located within a 90° interval relative to the center of the sphere 1 on one side of the hit reference point 241 located on the horizontal median line section 231, or within a 90° interval relative to the center of the sphere 1 on the other side of the hit reference point 241 located on the horizontal median line section 231, or on both sides of the hit reference point 241 located on the horizontal median line section 231. Point of approach angle of the ball 251.

[097] As an exemplary example, the angle of approach point of the ball 251a Petition 870260061403, dated 06 / 23 / 2026, p. 32 / 207 28 / 49 and the ball approach angle point 251b are both located on the horizontal midline section 231. The angle between the ball approach angle point 251a and the hit reference point 241 located on the horizontal midline section 231 relative to the center of sphere 1 is 45°, and the angle between the ball approach angle point 251b and the hit reference point 241 located on the horizontal midline section 231 relative to the center of sphere 1 is 45°. The ball approach angle point 251a is used to indicate the direction of the 45° running angle on the left side. The approach angle point of ball 251 b is used to indicate the direction of the 45° running angle on the right side, while the other approach angle point of ball 251 can be used to indicate the direction of the running angle of 30°, 60°, 70°, etc.

[098] Optionally, the angle of approach point of ball 251 includes, but is not limited to, a point of intersection between two lines, a circular point, an elliptical point, a triangular point, a square point and a polygonal point, or a point of special shape, and may be solid or hollow.

[099] Referring to Figures 1 and 2, alternatively, one end of each ball approach guide line 252 is connected to the ball approach angle point 251, and the other end of each ball approach guide line 252 is connected to one end of the initial aiming guide line 21 and to one end of the ball placement line 22.

[100] Optionally, the ball approach guide line 252 that is continuously extended, or a line that is not continuously extended, such as a dashed line, a dotted line, and a double dotted line.

[101] Optionally, the portion of the ball approach angle point 251 used by the left-handed player is omitted where the ball approach guide line 252 is located, reducing the difficulty for user 1000 to recognize the marking area 2 when using the soccer ball 100. At the same time, the ball approach angle point 251 is maintained so that user 1000 draws the ball approach guide line 252 accordingly. Petition 870260061403, dated 06 / 23 / 2026, p. 33 / 207 29 / 49 real needs.

[102] Referring to Figure 1, alternatively, the Hit Point Set 24 also includes the Upward Rotation Point 242. The interval between the Upward Rotation Point 242 and the Hit Reference Point 241 is defined. The Upward Rotation Point 242 is located in the cross-section where multiple Hit Reference Points 241 are situated. When the section where the initial aiming guide line 21 is located and the section where the ball placement line 22 is located are both perpendicular to the ground, the Upward Rotation Point 242 is located below one of the multiple Hit Reference Points 241.

[103] When playing a stationary ball, user 1000 applies a force that passes above the center of the ball without passing through the center of the ball below the rebound point at target height, thus kicking a ball that has the same angle as the “rebound point at target height”, but spins upwards. After “correct ball placement”, the Upward Rotation Point 242 is located below the corresponding rebound reference point 241. When user 1000 kicks the ball towards the Upward Rotation Point 242, he can kick the corresponding upward spin of the rebound reference point 241, which can cause user 1000 to face the upward spin helping to improve the efficiency and effect of the training.

[104] Optionally, the number of upward rotation points 242 is a multiple. Each upward rotation point 242 is located on the side of a hit reference point 241 away from the initial aiming guide line 21.

[105] Optionally, the upward rotation point 242 includes, but is not limited to, a point of intersection between two lines, a circular point, an elliptical point, a triangular point, a square point and a polygonal point, or a point of special shape, and may be solid or hollow.

[106] With regard to Figure 1, alternatively, the Beat Point Set 24 also includes a first lateral rotation point 243 and a second lateral rotation point 244. In the direction perpendicular to the cross-section where Petition 870260061403, dated 06 / 23 / 2026, p. 34 / 207 30 / 49 initial sight guide line 21, the first lateral rotation point 243 is away from one of the multiple hit reference points 241. In the direction perpendicular to the cross-section where the initial sight guide line 21 is located, the second lateral rotation point 244 is away from the upward rotation point 242.

[107] When kicking a ball in a set play, user 1000 applies a lateral force that passes through the center of the ball without passing through the center of the ball, thus kicking a ball that has the same angle of exit as the “point of impact at target height”, but which rotates laterally. After correct placement of the ball, if we consider the section of the horizontal midline 231 as the position of the “equator” of sphere 1, then the first lateral rotation point 243 and the corresponding hit reference point 241 are located at similar “latitude” positions, and the second lateral rotation point 244 and the upward rotation point 242 are located at similar “latitude” positions. After correct placement of the ball, the first lateral rotation point 243 is located next to the corresponding hit reference point 241, the second lateral rotation point 244 is located on the side corresponding to the upward rotation point 242.User 1000 playing towards the first lateral pivot point 243 can give a side effect corresponding to the batting reference point 241, user 1000 playing towards the second lateral pivot point 244 can give an “upward side effect” corresponding to the upward pivot point 242, allowing user 1000 to help improve the efficiency and effect of the training.

[108] Referring to Figure 1, alternatively, the distance between the first lateral rotation point 243 and the horizontal median line section 231 is equal to the distance between the corresponding beat reference point 241 and the horizontal median line section 231. The distance between the second lateral rotation point 244 and the horizontal median line section 231 is equal to the distance between the upward rotation point 242 and the horizontal median line section 231. Optionally, the deviation between the angle between the first lateral rotation point Petition 870260061403, dated 06 / 23 / 2026, p. 35 / 207 31 / 49 243 and the second section of the horizontal median line 231 with respect to the center of sphere 1 and the angle between the corresponding beat reference point 241 and the second section of the horizontal median line 231 with respect to the center of sphere 1 is within 5 degrees; The deviation between the angle between the second lateral rotation point 244 and the section of the horizontal median line 231 with respect to the center of sphere 1 and the corresponding angle between the upward rotation point 242 and the section of the horizontal median line 231 with respect to the center of sphere 1 is within 5 degrees.

[109] Referring to Figure 1, it can be understood that, alternatively, After correct placement of the ball, the striking reference point 241 is equipped with a first lateral rotation point 243 on the left and right sides, and a second lateral rotation point 244 on both the left and right sides of the ascending rotation point 242, so that the user 1000 can run from the left or right side and practice the lateral effect using the left or right foot to touch the ball.

[110] Optionally, the number of first lateral rotation points 243 is a multiple. Each two first lateral rotation points 243 are located on either side of a hit reference point 241 perpendicular to the transverse direction of the initial aiming guide line 21. Optionally, the number of second lateral rotation points 244 is a multiple. Each two second lateral rotation points 244 are located on either side of an upward rotation point 242 perpendicular to the transverse direction of the initial aiming guide line 21.

[111] Optionally, the first lateral rotation point 243 includes, but is not limited to, a point of intersection between two lines, a circular point, an elliptical point, a triangular point, a square point and a polygonal point, or a point of special shape, and may be solid or hollow. The second lateral rotation point 244 includes, but is not limited to, a point of intersection between two lines, a circular point, an elliptical point, a triangular point, a square point and a polygonal point, or a point of special shape, and may be solid or hollow. Petition 870260061403, dated 06 / 23 / 2026, page 36 / 207 32 / 49

[112] Referring to Figure 8, the central axis can also be defined as the intersection of the section where the initial aiming guide line 21 is located and the section where the ball placement line 22 is located. marking area 2 also includes follow-on guide mark 29, follow-on guide mark 29 includes multiple follow-on angle points 291 (including the first follow-on angle point 291a and the second follow-on angle point 291b) and multiple follow-on guide lines (including the first follow-on guide line 291a and the second follow-on guide line 291b).The angles between the cross-sections where the tracking angle point 291 and the center axis are located and the cross-sections where the initial aiming guide line is located are different, with each tracking angle point 291 located on a tracking guide line; When the section where the initial aiming guide line 21 is located and the section where the ball placement line 22 is located are both perpendicular to the ground, each section where the tracking guide line is located is perpendicular to the ground.

[113] The tracking action (also understood as the action of following / taking a step) refers to the action of following performed by the part of the foot that comes into contact with the point of impact on the surface of the ball, with a specific direction of movement and trajectory. Different types of hits have different initial tracking angles.

[114] Specifically, when the user kicks a stationary ball, different tracking directions relative to the soccer ball can affect factors such as the direction of the force exerted by the user's foot during the kick.

[115] Furthermore, each point of the following angle 291 and section of the central axis form an angle with the section where the initial aiming guide line 21 is located, which is used to guide the user's lateral angle of following.

[116] In the example above, the section where the Following Guide Line is located is the section where the following angle point 291 and the central axis are located, after correct ball placement. When the user positions themselves on the positive side of the section where the Following Guide Line is located Petition 870260061403, dated 06 / 23 / 2026, p. 37 / 207 33 / 49 tracking corresponding to the tracking angle to be practiced, the tracking guide line in the user's vision will appear as a straight line, which can be used to indicate the direction and improve the user's recognition of the tracking direction, which is beneficial for improving the user's recognition of the tracking direction horizontally. Efficiency and effectiveness of directional exercise training.

[117] It is worth noting that during the “inside-foot shot with side effect”, when the player runs naturally along the second running trajectory 251B at an angle gamma relative to the direction of the ball, where gamma = 45°, the direction of the supporting foot 1002 and the (lateral) direction of the following foot 1001 after landing will generally, naturally, be approximately the same, and both will form an angle of about 30° with the running line. At this moment, the initial (lateral) direction of the following foot will automatically form an angle difference β with the (lateral) direction of the ball = 15°.

[118] At this point, if the section where the Tracking Guide Line is located is also set at a 15-degree angle relative to the section where the Initial Aiming Guide Line 21 is located, when the kicking foot 1001 kicks the inside of the metatarsal bone on the instep towards the first lateral rotation point a243a, the initial direction of the actual tracking exit line (transverse) will naturally be parallel to the first Tracking Guide Line 29a on the sphere at a 15-degree angle, then the soccer ball 100 will produce a stable lateral rotation and follow the Initial Aiming Guide Line 21. Fly forward accurately in the direction. Observing whether the initial direction of the first actual lateral trajectory 292a is parallel to the first Tracking Guide Line 291a on the sphere can help determine if the actual lateral tracking angle is correct, allowing the user to practice and shape the posture that produces a natural and stable lateral tracking angle.

[119] Furthermore, observing whether the corresponding rotation of the sphere generated by the above tracking angles is appropriate and effective (to make Petition 870260061403, dated 06 / 23 / 2026, page 38 / 207 34 / 49 with the soccer ball 100 producing a suitable lateral rotation arc for left / right displacement of the sphere at a distance), for example, adjusting it for a 60-degree run-up to kick the first lateral rotation point 283b, to generate a second tracking trajectory 292b parallel to the second tracking guide line 29b in the figure and forming a 30-degree lateral angle with the ball, the soccer ball 100 produces a left / right displacement at a distance when exiting the tracking at a 15-degree lateral angle under a 45-degree run-up. The amount will be different. Through the adjustments and tests above, it can help the user find the appropriate run-up angle and tracking angle.

[120] Referring to Figure 3, alternatively, marking area 2 also includes penalty kick guide mark 26. Penalty kick guide mark 26 includes the first penalty kick angle point 261, the second penalty kick angle point 262, the third penalty kick angle point 263 and the fourth penalty kick angle point 264, which are used to instruct User 1000 aiming at the four corners of the goal when taking a penalty kick.

[121] The practiced plays include penalty kicks taken from the penalty mark in front of the goal. The first point of the penalty kick angle 261, the second point of the penalty kick angle 262, the third point of the penalty kick angle 263 and the fourth point of the penalty kick angle 264 can correspond to the four corners of the goal in relation to the center of the ball 1, so that the action of the user 1000 kicking towards the corner of the goal can be helping to improve the efficiency and effect of the training.

[122] Referring to Figure 3, alternatively, the first point of the penalty kick angle 261 and the second point of the penalty kick angle 262 are located on the horizontal midline section 231. The first point of the penalty kick angle 261 and the second point of the penalty kick angle 262 are spaced at intervals. When in use, point to the guide line. Petition 870260061403, dated 06 / 23 / 2026, p. 39 / 207 35 / 49 of initial aiming 21 to the center of the goal. The distance between the first point of the penalty kick angle 261 and the initial aiming guide line 21 is equal to the distance between the second point of the penalty kick angle 262 and the initial aiming guide line 21. The angle between the first point of the penalty kick angle 261 and the second point of the penalty kick angle 262 in relation to the center of sphere 1 is 35-39 degrees. The third point of the penalty kick angle 263, the first point of the penalty kick angle 261, and the cross-section where the center of sphere 1 is located are perpendicular to the horizontal midline section 231. The angle between the third point of the penalty kick angle 263 and the first point of the penalty kick angle 261 with respect to the center of sphere 1 is 10.4-12.4°.The fourth point of the penalty kick angle 264, the second point of the penalty kick angle 262, and the cross-section where the center of sphere 1 is located are perpendicular to the section of the horizontal midline 231. The angle between the fourth point of the penalty kick angle 264 and the second point of the penalty kick angle 262 with respect to the center of sphere 1 is 10.4-12.4°. When the cross-sections of the initial aiming guide line 21 and the ball placement line 22 are both perpendicular to the ground, the third point of the penalty kick angle 263 and the fourth point of the penalty kick angle 264 are both located below the section of the horizontal midline 231.

[123] According to the distance between the penalty mark and the goal (normally 12 yards, about 10.97 m), the size of the goal (normally 8 yards wide, about 7.32 m, and 8 feet high, about 2.44 m) and the size of the ball 1 (taking as an example the standard size of ball 5, with a diameter of about 22 cm), After correct placement of the ball, it can be calculated that the angle between the lower left and lower right corners of the goal and the penalty mark is about 36.9°, the angle between the upper left corner of the goal and the section of the horizontal center line 231 is about 11.4°, and the angle between the upper right corner of the goal and the correct section of the ball is about 11.4°. Petition 870260061403, dated 06 / 23 / 2026, p. 40 / 207 36 / 49 The angle between the horizontal midline section 231 is approximately 11.4°. Therefore, the relative positions of the first penalty angle point 261, the second penalty angle point 262, the third penalty angle point 263, and the fourth penalty angle point 264 in relation to the center of sphere 1 can correspond to the four corners of the goal, respectively, so that user 1000 can kick towards the corner of the goal during penalty kicks, helping to improve the efficiency and effect of the training.

[124] Referring to Figure 3, alternatively, After correct placement of the ball, when the first point of the penalty kick angle 261 is located at the kick reference point 241 defined in the horizontal midline section 231 of sphere 1, the first point of the penalty kick angle 261 corresponds to the lower right corner of the goal, the second point of the penalty kick angle 262 corresponds to the lower left corner of the goal, the third point of the penalty kick angle 263 corresponds to the upper right corner of the goal and the fourth point of the penalty kick angle 264 corresponds to the upper left corner of the goal.

[125] As an exemplary example, the angles between the first point of the penalty kick angle 261 and the second point of the penalty kick angle 262 in relation to the center of sphere 1 are 35°, 36°, 36.9°, 37°, 37.5°, 38°, 38.5°, 39°, etc. The angles between the third point of the penalty kick angle 263 and the first point of the penalty kick angle 261 in relation to the center of sphere 1 are 10.4°, 11°, 11.4°, 12°, 12.4°, etc. The angles between the fourth point of the penalty kick angle 264 and the second point of the penalty kick angle 262 with respect to the center of sphere 1 are 10.4°, 11°, 11.4°, 12°, 12.4°, etc.

[126] Referring to Figure 3, alternatively, connect the first point of the penalty kick angle 261, the second point of the penalty kick angle 262, the fourth point of the penalty kick angle 264 and the third point of the penalty kick angle 263 in sequence to indicate the interval Petition 870260061403, dated 06 / 23 / 2026, p. 41 / 207 37 / 49 impact points within the goal area when the user performs a penalty kick, helping to improve the efficiency and effect of the training.

[127] After connecting the first point of the penalty angle 261, the second point of the penalty angle 262, the fourth point of the penalty angle 264 and the third point of the penalty angle 263, the area within the four-point interval corresponds to the goal interval, so that user 1000 can kick towards the position within the goal interval when executing a penalty.

[128] The penalty guide mark 26 also includes the first goal simulation line 265, the second goal simulation line 266, the third goal simulation line 267 and the fourth goal simulation line 268. The two ends of the first goal simulation line 265 are connected, respectively, to the first point of the penalty angle 261 and the third point of the penalty angle 263. The section where the first goal simulation line 265 is located coincides with the section where the first point of the penalty angle 261 and the central axis 232 are located. The two ends of the second goal simulation line 266 are connected, respectively, to the second point of the penalty angle 262 and the fourth point of the penalty angle 264. The section where the second goal simulation line 266 is located coincides with the section where the second point of the penalty angle 262 and the central axis 232.The two ends of the third line of Goal Simulation 267 are connected, respectively, to the third point of the penalty kick angle 263 and to the fourth point of the penalty kick angle 264. The two ends of the fourth line of Goal Simulation 268 are connected, respectively, to the first point of the penalty kick angle 261 and to the second point of the penalty kick angle 262. The section where the fourth line of Goal Simulation 268 is located coincides with the section of the horizontal midfield line 231.

[129] Referring to Figures 1 and 3, optionally, the sight guide line Petition 870260061403, dated 06 / 23 / 2026, p. 42 / 207 38 / 49 initial 21, the ball placement line 22 and the ball approach guide mark 25 have several groups, with the strike point set 24 associated with one group of positions and the penalty kick guide mark 26 associated with the other group of positions. Optionally, the strike point set 24 and the penalty kick guide mark 26 can be associated with positions in the same group as the initial aim guide line 21, ball placement line 22 and ball approach guide mark 25.

[130] Optionally, the first point of the penalty kick angle 261, the second point of the penalty kick angle 262, the third point of the penalty kick angle 263, and the fourth point of the penalty kick angle 264 includes, but is not limited to, a point of intersection between two lines, a circular point, an elliptical point, a triangular point, a square point and a polygonal point, or a point of special shape, and may be solid or hollow. The first Goal Simulation line 265, the second Goal Simulation line 266, the third Goal Simulation line 267 and the fourth Goal Simulation line 268 that is continuously extended, or a line that is not continuously extended, such as a dashed line, a dotted line and a double dotted line.

[131] Referring to Figures 2 and 4, alternatively, the marking area2 also includes the assistance guide mark 27. The assistance guide mark 27 includes the assistance hit line 271. When the section where the initial aiming guide line 21 is located and the section where the ball placement line 22 is located are both perpendicular to the ground, the section where the assistance hit line 271 is located is perpendicular to the ground.

[132] After “correct ball placement”, the section where the assist hit line 271 is located is also perpendicular to the ground. The assist hit line 271 can also be used in User 1000’s view as presented as a “straight line” in the user’s view to guide the definition of the target hit direction. Referring to the intersection point (center hit point) between the assist hit line 271 and the hit line Petition 870260061403, dated 06 / 23 / 2026, p. 43 / 207 39 / 49 assist rebound 271 and the horizontal midline section 231, User 1000 can draw points or lines in their vicinity as needed, such as the rebound point set 24, ball approach guide mark A25 and penalty kick guide mark 26 were used, and the assist rebound line 271 was used in reference to the initial aim guide line 21 to test new rebound effects. Thus, User 1000 can adjust their training objectives according to their actual needs, improving the efficiency and effectiveness of the training.

[133] Optionally, one end of the assist beat line 271 is connected to one end of the initial sight guide line 21. The section where the assist beat line 271 is located coincides with the section where the initial sight guide line 21 is located.

[134] Referring to Figures 2 and 4, alternatively, the Assistance Guide Mark 27 also includes the Assistance Beat Reference Point 272. The Assistance Beat Reference Point 272 is located at the intersection of the Assistance Beat Line 271 and the Horizontal Centerline Section 231. The Assistance Beat Reference Point 272 serves as a reference for the Beat Reference Point 241 located on the Horizontal Centerline Section 231.

[135] It is worth noting that, near this intersection, there is a complete blank area outside the assist hit line 271, and the spherical material of this blank area is made of non-PVC material that can be colored with an oil-based marker. Used to add auxiliary labels, such as Hit Point Set, Ball Approach Guide Mark or Tracking Guide Mark for various effects you want to test in this blank area.

[136] Optionally, when the cross-sections of the initial aiming guide line 21 and the ball placement line 22 are both perpendicular to the ground, and both the initial aiming guide line 21 and the ball placement line 22 are located above the horizontal midline section 231, the assist batting line 271 is located below the midline section Petition 870260061403, dated 06 / 23 / 2026, p. 44 / 207 40 / 49 horizontal 231.

[137] Optionally, the assist beat line 271 which is continuously extended, or a line which is not continuously extended, such as a dashed line, a dotted line and a double dotted line. Assist beat reference point 272 includes, but is not limited to, a point of intersection between two lines, a circular point, an elliptical point, a triangular point, a square point and a polygonal point, or a point of special shape, and may be solid or hollow.

[138] Referring to Figures 1 and 2, alternatively, the marking area 2 also includes a first oscillation point 281 and a second oscillation point 282. The first oscillation point 281 and the second oscillation point 282 are located at both ends of the central axis 232, respectively.

[139] After “correct ball placement”, one of the first swing points 281 and the second swing point 282 must be located on the top of sphere 1, and the other must be located on the bottom of sphere 1. User 1000 can help adjust the placement posture of sphere 1, using the relative positions on the ground of the first swing point 281 and the second swing point 282. They can also invert and swap the positions of the first swing point 281 and the second swing point 282, allowing left / right footed players to jointly use most of the markings on the sphere (except the Penalty Kick Strike Point / Guide Mark Set), thus improving the accuracy and efficiency of sphere 1 placement, and leading to improved training efficiency.

[140] Optionally, the first oscillation point 281 includes, but is not limited to, a point of intersection between two lines, a circular point, an elliptical point, a triangular point, a square point and a polygonal point, or a point of special shape, and may be solid or hollow. The second oscillation point 282 includes, but is not limited to, a point of intersection between two lines, a point Petition 870260061403, dated 06 / 23 / 2026, page 45 / 207 41 / 49 circular, an elliptical point, a triangular point, a square point and a polygonal point, or a point of a special shape, and can be solid or hollow.

[141] Optionally, initial aiming guide line 21, ball placement line 22, strike reference point 241, upward rotation point 242, first lateral rotation point 243, second lateral rotation point 244, ball approach guide mark 25, penalty kick guide mark 26, assist guide mark 27, first placement point 281, second placement point 282 and follow-up guide mark 29 can be set with the same color or with different colors separately.

[142] Optionally, marking area 2 can be sprayed onto sphere 1 with paint or affixed to sphere 1 with stickers or printed onto sphere 1.

[143] Pigment spraying, sticker application and printing methods can improve the speed and accuracy of setting up marking area 2 on sphere 1 and increase the production efficiency of soccer ball 100.

[144] Referring to Figure 6, alternatively, the use of the soccer ball 100 includes swinging, running preparation, batting and tracking movements.

[145] Ball Balance: Using the initial aiming guide line 21 and the ball placement line 22 as visual references, make the initial aiming guide line 21 visually “perpendicular” to the ground and the ball placement line 22 visually “perpendicular” to the ground. Then, rotate the sphere 1 to align the initial aiming guide line 21 with the defined target position.

[146] Running preparation: Based on the running angle to be practiced, select the corresponding ball approach angle point 251 or ball approach guide line 252 and move away from sphere 1 in the direction indicated by the ball approach angle point 251 or ball approach guide line 252 to the defined distance. In User 1000's visual view, the section where the ball approach angle point 251 and the central axis 232 are located, i.e., the ball approach section section, Petition 870260061403, dated 06 / 23 / 2026, p. 46 / 207 42 / 49 is “a straight line” that forms an intersection with the ground and, in User 1000’s visual perception, the ball approach guide line 252 appears as a “straight line”; Then, by moving the body to the left or right, select the appropriate route parallel to the intersection of the ground and the ball approach section as the final running route. As an exemplary example, Referring to Figure 2, the final running route corresponding to the ball approach angle point 251a is the first running route 251A, which is parallel to the ball approach section corresponding to the ball approach angle point in Figure 2.

[147] Strike: Aim at one of the strike reference points 241, upward rotation point 242, first lateral rotation point 243, second lateral rotation point 244 or penalty kick guide mark 26 to be taken, run towards sphere 1 and finally strike the target position on sphere 1 with the foot kick 1001.

[148] In the related technology, user 1000 uses the formal action habits and muscle memory during the practice of set plays. At the moment of striking the ball, the distance relationship between the kicking foot 1001 used to touch the ball and the user 1000's supporting foot 1002 is basically fixed. And the user 1000's kicking foot 1001 is used to touch the ball in a relatively fixed position (like the metatarsal bone on the instep) at the point where the ball 1 is touched during each practice. If the position of the supporting foot 1002 in relation to the ball 1 changes during each practice, in order to maintain the designated position of the kicking foot 1001 touching the ball and touching the designated position of the ball 1, the user 1000's body posture needs to be adjusted accordingly, causing the movement to become distorted and unable to touch the ball naturally and forcefully, resulting in poor ball quality and reduced training effectiveness.Therefore, in each exercise, it is necessary to maintain the fixed position of the user's supporting foot 1002 in relation to sphere 1.

[149] Referring to Figure 6, the disclosed embodiment provides a training component 200. Training component 200 includes the Foot marker. Petition 870260061403, dated 06 / 23 / 2026, p. 47 / 207 43 / 49 support 210 and the soccer ball 100, as described in the embodiments above.

[150] The Foot Support marker 210 includes a side positioning segment 2102, a first marking portion 2103 and a second marking portion 2104. The side positioning segment 2102 is configured to resist external forces and deform, and is perpendicular to the cross-section where the initial aiming guide line 21 is located when in use. The second marking portion 2104 is located at the end of the lateral positioning segment 2102. The first marking portion 2103 is located on the lateral positioning segment 2102 and can slide freely on the lateral positioning segment 2102 to adjust the distance between the first marking portion 2103 and the second marking portion 2104, which is used to guide the predefined landing point of the user's support foot 1002 on the ground, forming the positional relationship between the support foot 1002 and the soccer ball 100.

[151] It should be noted that the lateral positioning segment 2102 can be manufactured with soft rope materials that will not be crushed by the football shoes, so that the lateral positioning segment 2102 will not be crushed by the football shoes after prolonged use.

[152] The football 100 can generate a mathematical “orthographic projection” on the ground (similar to the perspective where the eyes are directly above the football 100 and look down at the football 100), which is a regular circle. The orthographic projection of all points on the sphere (including the point of impact) will also be in a fixed position on the orthographic projection of sphere 1 of this regular circle on the ground, and the positional relationship of the orthographic projection between all points on the sphere (such as the striking reference point 241b and 241a) is also fixed on the ground.Refer to Figure 6; the various structures shown in Figure 6 are the corresponding orthographic projections of each structure.

[153] The actual point of impact is located at a fixed height above the Petition 870260061403, dated 06 / 23 / 2026, p. 48 / 207 44 / 49 “orthographic projection of the impact point” on the ground, therefore the positional relationship between the actual impact point and its “orthographic projection of the impact point” on the ground is fixed. By adjusting the two-dimensional positional relationship between the first marking portion 2103 on the ground (indicating the landing point of the support foot 1002) and the specific impact point on the ground, the positional relationship between the landing point of the support foot 1002 and the actual impact point can be adjusted.

[154] First, position the Support Foot marker 210 in a position approximately next to the penalty mark on the ground, ensuring that the side positioning segment 2102 is perpendicular to the starting line and held in place thereafter. After “correct ball placement”, by moving the football to the left or right, set the distance between the cross-section of the initial aiming guide line 21 and the second marking portion 2104 of the Support Foot marker 210 to the length of the sphere's radius 1 and hold it thereafter. Adjust the lateral distance of the First marking portion 2103 relative to the section where the Initial aiming guide line 21 is located by sliding the First marking portion 2103 on the side positioning segment 2102.Finally, by moving the soccer ball 100 forward or backward around the section where the initial aiming guide line 21 is located as an axis, the position of the lateral positioning segment 2102 in relation to the striking point assembly 24 on the ground can be determined. This will adjust the positional relationship between the landing point of the supporting foot 1002 and the actual striking point, and will provide guidance for the “correct positioning” of the supporting foot 1002 for the user 1000, facilitating repeated practice of the supporting foot 1002 positioning by the user 1000 and increasing the effectiveness of the training.

[155] As an exemplary example, the First marking portion 2103 is used to indicate the position of the middle of the medial foot or medial ankle of the user's supporting foot 1002 1000.

[156] Referring to Figure 6, alternatively, the Support Foot marker 210 Petition 870260061403, dated 06 / 23 / 2026, p. 49 / 207 45 / 49 also includes a length reference segment 2101. The length reference segment 2101 is connected to the side positioning segment 2102 and is located at the position of the second marking portion 2104. The length of the length reference segment 2101 is used as a dimensional reference to adjust the distance between the first marking portion 2103 and the second marking portion 2104, or as a reference for the vertical distance between the extension direction of the side positioning segment 2102 and the orthographic projection of the Beat Point Assembly 24.

[157] By folding the length reference segment 2101 to become parallel and overlapping the lateral positioning segment 2102 and sliding the First marking portion 2103 to adjust to its length reference segment of the length reference segment 2101, the position of the First marking portion 2103 in relation to the Second marking portion 2104 or the actual impact point can be quickly adjusted, and lead to an improvement in training efficiency.

[158] Referring to Figure 6, alternatively, the reference segment of length 2101 is configured to resist external forces and deform and, when in use, is parallel to the plane of the initial aiming guide line 21. When using the Support Foot marker 210, the length of the reference segment of length 2101 can also be used as a reference for the vertical distance between the extension direction of the lateral positioning segment 2102 and the orthographic projection of the Impact Point Assembly 24, in order to locate the relative position between the lateral positioning segment 2102 and the impact point in the extension direction of the lateral positioning segment 2102.

[159] Optionally, the length reference segment 2101 and the side positioning segment 2102 are rope-like structures that can be bent and deformed.

[160] Referring to Figure 6, alternatively, the reference length segment 2101 and the lateral positioning segment 2102 are integrally formed structures. The integrally formed segments of the segment of Petition 870260061403, dated 06 / 23 / 2026, page 50 / 207 The 46 / 49 length reference 2101 and the lateral positioning segment 2102 are easy to transport and place, and the connection between the length reference segment 2101 and the lateral positioning segment 2102 is stable, reducing the possibility of separation from the user during training and improving its service life.

[161] Optionally, the length reference segment 2101 and the side positioning segment 2102 are separate structures that can be formed by a single chord or by a combination of several chords.

[162] Referring to Figure 6, alternatively, the reference length segment 2101 and the lateral positioning segment 2102 can be tied together to form a node.

[163] When giving knots, it is convenient to define the length of the reference segment of length 2101 (for example, defining it as the length of the diameter of a standard 4a or 5a ball), in order to adjust the position of the relative orthographic projection of the Beat Point Set 24, as needed.

[164] Referring to Figure 6, optionally, the First Marking Portion 2103 is tied to the Lateral Positioning Segment 2102 using another short cord, such as by tying a knot. Alternatively, the First Marking Portion 2103 can be formed by tying a knot in the Lateral Positioning Segment 2102 itself.

[165] As an exemplary example, when sphere 1 adopts a standard sphere no. 5 with a circumference of 69 cm, the vertical distance L1 between the extension of the lateral positioning segment 2102 and the projection of the strike point assembly 24 (illustrated in Figure 6 as the vertical distance between the extension of the lateral positioning segment 2102 and the projection of the strike reference point 241a) is about 2.2 cm (approximately 10% of the diameter of sphere 1). The distance L2 between the first marking portion 2103 and the second marking portion 2104 is about 15.4 cm (about 70% of the diameter of sphere 1), which can cause the position of the first marking portion to be... Petition 870260061403, dated 06 / 23 / 2026, page 51 / 207 47 / 49 2103 satisfies the following condition: the vertical distance L1 between the extension of the lateral positioning segment 2102 and the projection of the Hitting Point Assembly 24 is approximately 2.2 cm; in the direction perpendicular to the cross-section where the initial aiming guide line 2, the first marking portion 2103 and the Hitting Point Assembly 24 meet, it is approximately 26.4 cm.

[166] Referring to Figure 6, the optional use of training component 200 includes rope swing, ball swing, ball displacement, running, landing of the support foot and batting the ball. Rope placement: First, place the Support Foot marker 210 in a position approximately next to the penalty mark on the ground and then set the orientation of the lateral positioning segment 2102 and the length reference segment 2101. Make the lateral positioning segment 2102 perpendicular to the starting line and keep it so, and make the length reference segment 2101 parallel to the starting direction and keep it so. Adjust the position of the First Marking Portion 2103 and adjust the distance L2 between the First Marking Portion 2103 and the Second Marking Portion 2104 to the correct position.

[167] Balance the ball: Make the initial aiming guide line 21 “perpendicular” to the ground, make the ball placement line 22 “perpendicular” to the ground, rotate the soccer ball into place and align the initial aiming guide line 21 with the direction of the preset batting target.

[168] Movement of the sphere: When moving the soccer ball 100 to the left or right, the vertical distance between the section where the initial aiming guide line 21 and the second marking portion 2104 of the support foot marker 210 is equal to the length of the sphere's radius 1 and is maintained from there (at this point, the reference segment of length 2101 is in a “tangent” relationship with the circular line of the sphere 1 projected onto the ground). Finally, when moving the sphere 1 forward or backward in the direction indicated by the initial aiming guide line 21, the position of the extension of the lateral positioning segment 2102 is determined in relation to the Assembly Petition 870260061403, dated 06 / 23 / 2026, p. 52 / 207 48 / 49 of rebound point 24 on the ground. This adjusts the positional relationship between the landing point of the support foot 1002 and the actual impact point, and provides guidance on the “correct positioning” of the support foot 1002 for the user 1000, facilitating repeated practice of the positioning of the support foot 1002 by the user 1000 and improving the effectiveness of the training.

[169] Acceleration: According to the acceleration angle to be practiced, select the corresponding ball approach angle point 251 or ball approach guide line 252 and move away from sphere 1 to the distance defined in the direction indicated by the ball approach angle point 251 or ball approach guide line 252. In User 1000’s visual perception, the section where the ball approach angle point 251 and the central axis 232 meet, i.e., the ball approach section, is “one”. A straight line forms an intersection with the ground and, in User 1000’s visual perception, the ball approach guide line 252 appears as a “straight line”; Then, when moving the body to the left or right, select the appropriate path parallel to the intersection of the ground and the ball approach section as the final running route.As an exemplary case, referring to Figure 2, the final running path corresponding to the ball approach angle point 251a is the first running path 251A, which is parallel to the ball approach section corresponding to the ball approach angle point in Figure 2.

[170] Landing the support foot: After running, overlap the designated position on the sole of the support foot 1002 (such as the middle of the inside side of the sole of the user's support foot 1002 or the position of the bare inside side of the foot) with the position defined by the First marking portion 2103 of the Support Foot marker 210 on the ground.

[171] Shot: Aim at one of the shooting reference points 241, upward rotation point 242, first lateral rotation point 243, second lateral rotation point 244, and the penalty kick guide mark 26 to be taken and finally hit the position on the target sphere 1 with a foot kick 1001. Petition 870260061403, dated 06 / 23 / 2026, p. 53 / 207 49 / 49

[172] In this application, the various “lines” in marking area 2 are linear regions with a given width and the various “points” are point regions with a given diameter.

[173] Furthermore, experts in the field should recognize that the embodiments mentioned above are used only to illustrate the present application and not to limit it. Any appropriate changes and variations made to the embodiments mentioned above, within the substantive spirit of the present application, are within the scope of the disclosure of the present application. INDUSTRIAL APPLICABILITY

[174] In summary, this disclosure provides a soccer ball and a training component that can guide users in using the disclosed soccer ball for training set plays. Through the initial aiming guide line and the ball placement line, users can quickly straighten and aim the ball at the batting target, completing the correct ball placement. This ensures that the positions of each batting reference point relative to the ground, the ball, and the predetermined batting target are correctly fixed. After the correct run-up and kick, the direction and flight trajectory of the ball will also be the same and fixed.The user can assess whether they accurately and effectively hit the desired point of contact with the ball in their full set of kicking actions based on the effect of their own kick, in order to further improve and refine various elements of the action, such as the angle and trajectory of the run-up, the landing of the supporting foot, the kicking posture, the ball tracking movements, etc. After becoming familiar with effective actions, they can form action habits and muscle memory, so that even when using a soccer ball without a marking area to kick the ball, they can apply the familiar details of the actions and consistently hit the specific striking effect during training. Therefore, using the soccer ball exercises with the marking area mentioned above, it is possible to improve the efficiency and effectiveness of goal kick practice training through the use of a soccer ball.
