[0001] TABLE TENNIS BALL RETRIEVAL SYSTEM

[0002] CROSS REFERENCE TO RELATED APPLICATIONS

[0003] This application claims the benefit of United States Provisional Application No. 63 / 600,219, filed November 17, 2023, which is hereby incorporated by reference in its entirety.

[0004] BACKGROUND OF THE INVENTION

[0005] Field of the Invention

[0006] The present invention pertains to the field of recreational activities, particularly table tennis or ping pong. More specifically, the invention addresses issues related to lower back pain and fatigue due to the repeated and highly frequent need to pick up ping pong balls that land on the ground at the end of rallies, occurring both during game play and practice. This invention also addresses the issues related to the delays in game play and practice caused by the need to bend over and pick up ping pong balls from the ground; typically at the end of each rally or point.

[0007] Description of the Related Art

[0008] Table tennis, a widely popular indoor sport also commonly referred to as ping pong, has been enjoyed by people of all ages and skill levels for over a century. The game involves fast-paced rallies that require quick reflexes, precision, and agility. In a typical table tennis game or during practice sessions, players use small, lightweight ping pong balls that often times land on the floor at the end of a rally. In table tennis, rallies usually last for a short period of time, creating the need for balls to be picked up off the ground with high frequency. Picking up table tennis balls is the major cause of delays between rallies during gameplay.

[0009] Picking up ping pong balls from the floor is a task that detracts from the flow and enjoyment of the game. This problem is especially pronounced during intensive training sessions, tournaments, or casual matches where numerous balls may collect on the floor. The interruptions caused by retrieving these balls disrupt the rhythm of the game and can be a source of frustration for players, and can reduce the number of repetitions per time period during practice sessions. Moreover, the physical act of bending down repeatedly to collect balls from the floor can lead to lower back strain and unnecessary discomfort for players, especially during extended gameplay. Such disruptions and physical discomfort can hinder the overall experience, making it less enjoyable and potentially discouraging players from participating in table tennis. The repetitive motion associated with the retrieval of ping pong balls from the floor, especially during extended gameplay or intensive training sessions, places undue stress on various parts of the body. Prolonged and frequent bending at the waist can strain the lower back, leading to musculoskeletal issues, including lower back pain. Players may also experience discomfort in their knees and hips, as the constant bending and rising places pressure on these joints potentially contributing to overuse injuries. These health problems not only affect the players' immediate physical comfort but can also result in long-term issues if the gameplay is not ergonomically sound.

[0010] The requirement to repeatedly bend over to pick up ping pong balls from the floor poses a significant barrier to individuals with physical limitations. Those with limited mobility, back problems, or other physical challenges may find it extremely difficult or even impossible to participate in the sport of table tennis. The need for constant bending and reaching to retrieve stray balls can be both physically demanding and painful for individuals with disabilities or mobility issues. As a result, these individuals may be discouraged from enjoying the game, further limiting their access to a fun and inclusive recreational and / or competitive activity. Addressing this issue through innovative solutions that reduce the physical demands of ping pong gameplay is essential to make the sport more accessible to a broader and more diverse audience.

[0011] Various prior art devices have attempted to address this issue and related challenges with various ball collection mechanisms, such as ball retrievers or manual scoops. These mechanisms, however, often have limitations in terms of efficiency, speed, ease of use, and suitability to retrieve ping pong balls. They can still cause interruptions in the game, and they do not completely eliminate the need for players to manually pick up stray balls.

[0012] In the realm of table tennis and related patent documents, several innovations have attempted to address the problem of collecting ping pong balls more efficiently. One such example is found in United States Patent 5,810,681, titled "Apparatus for picking up and dispensing balls." This patent disclosure and other relevant devices provide a mechanism to stack balls within a cylinder. While such a mechanism is advantageous in association with picking up a plurality of balls during a break in play, such a device is somewhat time consuming and requires a rather significant stoppage in play if utilized by a player.

[0013] Another relevant patent, United States Patent 7,762,914, entitled "Ping pong ball retriever," discloses a more automated approach to controlling errant ping pong balls during play. This device employs a variety of faces at angles to controllably deflect errant ping pong balls into a desired location or receptacle during play. While it offers improved efficiency compared to manual methods of retrieving ping pong balls, the complexity of the system and the impracticality in association with the retrieval system can still result in game disruptions. It remains desirable, therefore, to provide a mechanism that allows for reduced stoppages during game play in association with table tennis.

[0014] Other previously discovered innovations employ tools and techniques to retrieve balls from the floor or ground via various uses of sporting-equipment connected and shoe 2000-connected devices. One such example is found in US Patent 9,089,741, hereby incorporated by reference in its entirety, titled "Golf ball grabber." This patent describes a golf ball-grabbing device for placement at the end of a golf club to retrieve a ball. This device, however, lacks aspects amenable for configuration to retrieve a ping pong ball. For example, it requires an elongate sporting device not typically present in association with the game of table tennis. It further requires three prongs and a more stable form to retrieve a golf ball, which is more solid and heavier than a ping pong ball. Application of such configuration of the retrieval end to a ping pong ball would likely irreversibly deform it, therefore destroying the ping pong ball.

[0015] Another such example is found in United States Patent Application 11 / 209,373 filed on August 23, 2005, hereby incorporated by reference in its entirety, titled “Golf Ball Teeing Apparatus.” This document discloses disposable golf ball-teeing device, when attached to the front half of footwear, aids a golfer to successfully position a golf ball onto a stationary tee. The device disadvantageously (in the context of table tennis) requires attachment to the bottom surface of a shoe, for example, to a cleat of a shoe. Cleated shoe are not allowed in association with table tennis since the sport is often times played in gymnasiums and / or rubberized flooring. This device is designed to have the golf ball sit on top of it during placement onto the tee, rather than securing the ball within the device to be lifted up to the hand. Moreover, table tennis requires rapid movement of the feet, and any interference between the bottom of a shoe and the floor, such as is caused in association with the device described in this reference, could cause a table tennis player to slip.

[0016] While these examples demonstrate that prior inventions have attempted to address the issue of ball collection, they underscore the persistent challenges in achieving a solution that is efficient, effective and unobtrusive during table tennis gameplay. The limitations of these existing technologies have driven the need for more innovative and effective solutions to enhance the table tennis experience. It remains desirable to advance an innovation that overcomes the limitations of existing solutions by significantly reducing the amount of time in between rallies to pick up balls, the risk of ping pong ball deformation, and the need to manually retrieve the ball from the floor. It also remains desirable to discover an alternative to processes that increase the likelihood of back pain and long-term health effects in association with ping pong ball retrieval.

[0017] Therefore, there is a need for an innovative solution that overcomes the problems associated with picking up ping pong balls from the floor. This invention aims to provide a novel and improved approach that enhances the gameplay experience by reducing disruptions and delays caused by stray balls, while also minimizing the physical strain on players.

[0031] DETAILED DESCRIPTION OF THE INVENTION

[0032] In the preferred embodiment, the shoe-mountable ping pong ball retention system 100 comprises a placement member to affix the system to a shoe 2000, optionally a flat member 200, a neck 210 from the flat member 200 leading up to the connection point 220 joining each of the dual prongs 300, and two radially curved dual prongs 300.

[0033] It will be appreciated by those skilled in the art that the placement member may be shaped in accordance with a variety of contours or aspects to ensure secure placement upon a shoe 2000. However, in association with the preferred embodiment, the placement member comprises a flat member 200 to ensure the widest compatibility in association with contemplated uses. In the preferred embodiment, the flat member 200 is approximately 0.5” tall by 1” wide. The bottom of the flat member 200 in association with a preferred method of use is positioned on the shoe 2000 approximately 0.1875” above the level of the floor. It will be appreciated by those skilled in the art The flat member 200 and neck 210 will have a thickness ranging from 0.0625 to 0.125 inches in association with the preferred embodiment. The neck 210 that extends from the flat member 200 begins at a height of approximately 0.6875” from the floor when the shoe 2000 is placed flat in association with its intended use. In an embodiment, the neck 210 curves radially toward the connection point 220 of the dual prongs 300. The neck 210 comprises a connection point 220 in an embodiment connecting with both of the dual prongs 300 at approximately a height of 1.4” from the floor when the shoe 2000 is placed flat in association with its intended use in association with the preferred embodiment. The width of the neck 210 piece extending to the dual prongs 300 will be approximately 0.25” in association with the preferred embodiment. The length of the neck 210 from the superior aspect of the flat member 200 to the dual prongs 300 at the connection point 220 will be approximately 0.62” in association with the preferred embodiment. In various alternative embodiments, the neck 210 may extend from the flat member 200 to the connection point 220 in a manner that generally corresponds to the path of the exterior aspect of a ping pong ball. An alternative embodiment of the invention is depicted by the exemplary configurations shown by Figs. 7-9. It is contemplated that other reconfigurations of the neck 210, flat member 200, connection point 220 and dual prongs 300 may occur and reflect various embodiments of the present invention.

[0034] In association with the preferred embodiment, the side of the flat member 200 opposing the dual prongs 300 is intended to receive a first hook and loop fastener piece 205, comprising an adhesive-backed piece of hook and loop fastener. In association with embodiments of the invention, the hook and loop fastener consists of Velcro. In the preferred embodiment, the first adhesive-backed hook and loop fastener piece 205 attached to the flat member 200 is of the dimensions of approximately 1 inch wide by 0.5 inches tall. In association with the preferred embodiment, the inferior aspect of the first square hook and loop fastener piece 205 aligns with the inferior edge of the flat member 200. In association with the preferred method of use, the first hook and loop fastener piece 205 adhered to the flat member 200 is configured to receive and create a strong, temporary bond with a second hook and loop fastener piece attached to the shoe 2000 in association with methods and devices well known in the art. Exemplary placements of the preferred embodiment upon a shoe 2000 in association with a preferred method of use are depicted within Figs. 6a and 6b.

[0035] The preferred embodiment further comprises a second hook and loop fastener piece attached to a shoe 2000. In an embodiment, the second hook and loop fastener piece comprises the dimensions of approximately 1 inch wide by 0.5 inches in height. In association with the preferred embodiment, the second hook and loop fastener piece further comprises an adhesive backing opposite the hook and loop fastener aspect. In the preferred use, the inferior edge of the second hook and loop fastener piece is placed upon the exterior aspect of the sole of the shoe 2000 approximately 0.1875 inches above the floor during its intended usage when the shoe 2000 is placed flat upon the floor. In various embodiments, the placement of the second hook and loop fastener piece may vary relative to the floor dependent upon the orientation and / or position of the shoe 2000 relative to the floor. In association with the preferred embodiment and method of use, the superior edge of the second hook and loop fastener is placed approximately 0.6875 inches above the level of the floor. In association with various embodiments, the configuration of the second hook and loop fastener piece is such that it creates a strong, temporary bond with a corresponding first hook and loop fastener piece 205 when they are pressed together in association with the intended uses as is well understood by artisans.

[0036] In the preferred embodiment, the superior aspect of the flat member 200 is connected to the prongs by a neck 210 at a connection point 220 with the dual prongs 300 by curving from the flat member 200 to the connection point 220 of the dual prongs 300. In various embodiments, the shape of the dual prongs 300 corresponds to the exterior of a table tennis ball. In association with various embodiments, the path of the dual prongs may travel vertically, substantially vertically, horizontally or substantially horizontally relative to the plane of the floor from the connection point 220 to any path corresponding to the exterior shape of a table tennis ball in association with the intended use as depicted by Fig. 6A. In the preferred embodiment, the dual prongs 300 and the flat member 200 are formed together during the manufacture of the system 100 in the form of a single piece. In an alternative embodiment, the dual prongs 300 are attached to the flat member 200 with adhesive.

[0037] In the preferred embodiment, the detachable portion of the ping pong ball retention system 100 comprises the flat member 200, the neck 210, and dual prongs 300. In various embodiments, the dual prongs 300 convene upon or proximal to the flat member 200 upon the neck 210 at a location distal to the flat member 200 of the detachable portion. In an embodiment, the dual prongs 300 resemble a wishbone shape. In an alternative embodiment, the dual prongs 300 comprise a curved center area extending from the flat member 200 substantially within the outermost aspects of the dual prong with a shape corresponding to the exterior aspect of a ping pong ball 1000.

[0038] In the preferred embodiment the curvature of the dual prongs 300 corresponds to the shape and dimensions of the external aspects of and curvature of a regulation sized ping pong ball 1000. In such manner, the inferior aspects of the dual prongs 300 in an embodiment follow the contours of the external aspects of, with sizing only slightly larger than, a regulation sized ping pong ball 1000, to facilitate retention of the regulation sized ping pong ball 1000 in association with the intended use as will be appreciated by those skilled in the art. In an embodiment, the dual prongs 300 during the intended use maintain continuous contact or near contact with the ping pong ball 1000 along the longitudinal axis and / or latitudinal axis. In the preferred embodiment, each of the dual prongs 300 are substantially cylindrical and longitudinally circular. Each of the dual prongs 300 follow a curvature around the ball 1000 corresponding to and slightly larger than the curvature of a ping pong ball 100. In association with the preferred embodiment, the curvature of each of the dual prongs 300 proceeds in the horizontal axis and then deviates from the horizontal axis to follow a curvature around the ball 1000 in the vertical axis. The present inventor has recognized the advantage of such configuration in that it minimizes the mass required by aspects of the invention, and thereby preserves the compactness associated with the preferred embodiment, while achieving the capability to properly retain a ping pong ball 1000. In association with alternative embodiments, such as those shown in Figs. 7-9, the curvature of each of the dual prongs follows a path substantially parallel to the plane of the floor during the step of an intended method of use as depicted by Fig. 6A. It is contemplated that the dual prongs 300 in the preferred embodiment maintain substantially continuous contact or near contact with a ping pong ball 1000 retained by the shoe-mountable ping pong ball retention system 100 in association with its intended uses. In association with various embodiments, the neck 210 of the system 100 follows a path from the flat member 200 to the connection point 220 corresponding to and slightly larger than the curvature of a ping pong ball 1000. It is likewise contemplated that the neck 210 in association with various embodiments maintains substantially continuous contact or near contact with a ping pong ball 1000 retained by the shoe-mountable ping pong ball retention system 100 in association with its intended uses.

[0039] In association with the preferred embodiment, each of the two prongs associated with the dual prongs 300 allow for the provision of retention forces in two directions in association with the retention of a ping pong ball 1000 during its intended use. More particularly, each of the two prongs associated with the dual prongs 300 in the preferred embodiment are configured to retain a ping pong ball 1000 by providing a compression force in the direction of the shoe 2000 and separately provide a retention force in a direction toward the other of the dual prongs 300 when the ping pong ball 1000 is retained therein, with the opposing force provided by the ping pong ball 1000 itself. In association with aspects of the preferred embodiment, these forces act to retain the ping pong ball 1000 within the dual prongs 300 and other aspects of the ping pong ball retention system 100 during the intended utilization.

[0040] The construction of aspects of the preferred embodiment, especially the dual prongs 300, are such that they require minimal and resilient deformation. Deformation of the prongs will occur at two primary levels in association with the preferred embodiment. The first level of deformation that occurs is that associated with the event of the prong tips 320 passing the greatest circumference of the ball 1000. The range of deformation of each of the dual prongs 300 at this point of largest circumference will correlate directly with the overall prong length and ridge depth associated with each of the dual prongs 300. This deformation at the first level of deformation will occur within the range of deformation of 0.08” and 0.17” in association with the preferred embodiment. The second level of deformation is a level of deformation that is less pronounced. This second level of deformation occurs during the securement of the regulation sized ping pong ball 1000 in association with the preferred embodiments and uses of the system. In association with the preferred embodiment, each retention ridge 310 located proximal to the end of each of the dual prongs 300 will extend approximately 0.0625” inwards toward the ball 1000 from each of the dual prongs 300. Further in association with the preferred embodiment, each of the prong tips 320 will deflect by approximately the same distance thereby off-setting the ball 1000 by that amount, until each of the dual prongs 300 regains exact curvature with the exterior of the ball 1000 as it extends back to the connecting neck 210. In the preferred embodiment, therefore, the retention ridge 310 increases the static coefficient of a ping pong ball 1000 thereby effectively allowing the ball retention system 100 to secure the ball 1000 effectively. In association with the preferred embodiment, each of the prongs associated with the dual prongs 300 requires minimal resilient deflection to retain a ball 1000, which the present inventor has recognized allow for enhanced usability by the wearer of a shoe 2000 comprising the shoe-mountable ping pong ball retention system 100.

[0041] In an embodiment, the dual prongs 300 further comprise shaped prong tips 320. In an embodiment, the shaped prong tips 320 comprise a substantially cylindrical shape approximately 0.1875” in diameter with a ridge at the end of each prong. It is contemplated that the cross-sectional shape of each or any of the dual prongs 300 may vary according to various embodiments. In the preferred embodiment, at least one or both of the dual prongs 300 further comprise a retention ridge 310. The retention ridge 310 is located proximal to the distal end(s) of each of the dual prongs 300. In the preferred embodiment, the retention ridge 310 comprises the same material as the dual prongs 300. In the preferred embodiment, each of the retention ridges 310 extends from the interior aspect of each of the dual prongs 300 approximately 0.0625 inches, an example of which is depicted in Fig. 4. It is contemplated that in an embodiment, the retention ridge 310 may create a slight separation between aspects of the dual prongs 300 and the ping pong ball 1000 in association with the intended use, thereby interrupting substantially continuous contact among the exterior aspect of the ping pong ball 1000 and the inferior aspect of the dual prongs 300.

[0042] In association with the preferred embodiment, aspects of the shoe-mountable ping pong ball retention system 100 comprise specific dimensions. In the preferred embodiment, the shape of the dual prongs 300 from the point where the dual prongs 300 intersect at the neck 210 with the flat member 2000 to the point of most superior aspect of the dual prongs 300 is defined by a radius corresponding to contour of the inferior aspect of the dual prongs 300 intended for substantially continuous contact with a ping pong ball 1000 during the intended use if each of the retention ridges 310 did not push the retained ping pong ball 1000 away. The distance is therefore appropriately defined in association with intended uses of the preferred embodiment from the center of the ping pong ball 1000 to the center of each of the cylindrical dual prongs 300. In association with the preferred embodiment, the radius of the ping pong ball 1000 plus the radius of either of the dual prongs 300 is approximately 0.8787 inches when the ping pong ball 1000 is retained within the shoe- mountable ping pong ball retention system 100.

[0043] In the preferred embodiment, each of the dual prongs 300 follow the horizontal plane curving around the ping pong ball 1000 along the center of the ball’s 1000 vertical axis starting from the point of intersection of the dual prongs 300. In an embodiment, each of the dual prongs 300 extend in opposite directions around the ball 1000, the highest point of the prongs (i.e. the point on each of the dual prongs 300 most distal from the ground when the foot is placed flat upon the ground in association with the preferred use) is approximately 0.14875 inches below the highest point of the ping pong ball 1000 (i.e. the point on the ping pong ball 1000 most distal from the ground when the foot is placed flat upon the ground in association with the preferred use) as shown in Fig. 6 of the shoe 2000- mountable ping pong ball 1000 retention system. In an embodiment, each of the dual prongs 300 change axis rotation from substantially horizontal to substantially vertical at the point of 90 degree horizontal rotation as they change direction to extend down to the most distal tips 320 of each of the dual prongs 300. The change in direction of each of the dual prongs 300 is defined by rotation around the horizontal axis running through the center of the ping pong ball 1000 and extending to each of the prong tips 320 in the vertical plane. In an embodiment, each of the dual prongs 300 are configured to maintain minimal or no separation between the outermost vertical plane of the ping pong ball 1000 and the outermost plane of each prong as shown in the Fig. 6 of the shoe 2000-mountable ping pong ball retention system 100. In an embodiment, the distance from the center of each of the substantially cylindrical dual prongs 300 to the center of each of the dual prongs 300 at the tips 320 or point most distal from the flat member 200 is approximately 1.3825”. In association with the preferred embodiment, each of the dual prongs 300 from the point where each of the dual prongs 300 intersect with each other at the approximate location of the neck 220 to the distal end of each of the dual prongs 300 comprises a total length of a minimum of 2 inches. In association with the preferred embodiment, the total length of the dual prongs 300 may be extended to a maximum length of up to approximately 2.13 inches. The present inventor has recognized that minimizing the length of the prong tips 320 is advantageous in order to keep clearance from each of the dual prongs 300 to the floor, thereby helping to ensure that the prong tips 320 do not come into contact with the floor during game play. In the preferred embodiment, the minimum prong length associated with each of the dual prongs 300 while still retaining the ping pong ball will be utilized, based on the range of anticipated approximate prong lengths, the approximate distance defined from the tip 320 of each of the dual prongs 300 to the floor will be approximately 0.5 to 0.65 inches which defines floor clearance of the ping pong ball retention system 100 in association with the intended use when a shoe 2000 is placed substantially flat upon a floor, as depicted by Fig. 6A.

[0044] In association with the preferred embodiment, the flat member 200, neck 210, and the dual prongs 300 are constructed from a polymer material. The selection of the polymer is critical to ensure that the components exhibit the necessary resilience and durability for the repeated use and deformation required during the retrieval of ping pong balls. In addition to acetal homopolymers, polyacetals, polyamides, polycarbonates, polyphenylenes, polyethylene terephthalates, and polysulfones, which have been previously mentioned, there are several other materials that could be considered for their advantageous properties.

[0045] The flat member 200, neck 210, and the dual prongs 300 may be constructed of alternative materials in various embodiments, including but not limited to the following: Thermoplastic elastomers (TPEs) are a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) which consist of materials with both thermoplastic and elastomeric properties. TPEs exhibit flexibility and high resilience, allowing for the necessary deformation without causing damage to the ping pong balls or the retention system itself.

[0046] Polypropylene (PP) is another suitable material known for its fatigue resistance, which would be beneficial for the repeated flexing of the dual prongs. Its inherent stiffness, combined with a good balance of chemical resistance and an ability to be adhered to with certain adhesives, makes it a viable option for the construction of the retention system.

[0047] Polyethylene (PE), particularly high-density polyethylene (HDPE), is known for its high strength-to-density ratio. HDPE could be used to create a lightweight yet robust retention system that can withstand the physical demands of the application.

[0048] Thermoplastic polyurethane (TPU) is renowned for its elasticity, transparency, and resistance to oil, grease, and abrasion. This material could provide a clear aesthetic to the retention system while maintaining the necessary flexibility and durability.

[0049] Polyoxymethylene (POM), also known as acetal, polyacetal, and polyformaldehyde, is a highly crystalline thermoplastic with high tensile strength, stiffness, and resistance to impact. POM could be particularly useful for the neck 210 and dual prongs 300, where rigidity is needed alongside resilience.

[0050] Nylon, a type of polyamide, is known for its high mechanical strength, rigidity, and thermal stability. It could be particularly advantageous for the flat member 200, which serves as the base for the retention system and requires a strong bond with the hook and loop fastener.

[0051] In association with various embodiments, the chosen polymer should have the ability to accept adhesives, allowing for secure attachment of the hook and loop fastener pieces. The polymer should also be non-destructive and capable of resilient deformation to ensure the longevity of the retention system and the safety of the ping pong balls during use. It is important to note that the specific polymer chosen may vary based on the desired balance of properties such as flexibility, strength, weight, and cost in association with various embodiments.

[0052] In association with embodiments of the shoe-mountable ping pong ball retention system 100, it is essential to specify the grade and characteristics of the materials used to ensure optimal performance. For instance, in association with the preferred embodiment the polymer selected for the dual prongs 300 must exhibit a high degree of flexibility and memory to return to its original shape after deformation. This is critical for the repeated action of gripping and releasing ping pong balls 1000 without causing damage or permanent deformation to the dual prongs 300. In an exemplary embodiment, a suitable grade of thermoplastic polyurethane (TPU) known for its excellent elongation and tensile strength properties could be utilized. TPU's inherent abrasion resistance and tear strength make it an ideal candidate for components that undergo frequent flexing and contact with the ground and ping pong balls 1000. Additionally, TPU's compatibility with various adhesives allows for secure attachment of the hook and loop fastener pieces 205, ensuring a robust and reliable connection to the shoe 2000.

[0053] Furthermore, the interaction between the retention system 100 and the ping pong balls 1000 is a critical consideration. The present inventor has recognized that the material in association with various embodiments must be soft enough to not damage the balls upon contact, yet firm enough to securely hold them during retrieval. In an exemplary embodiment, a polymer like high-density polyethylene (HDPE) could be employed for the flat member 200, providing a smooth surface that minimizes friction and wear on the ping pong balls 1000 retained within. HDPE is also resistant to chemicals, moisture, and impacts, contributing to the system's long-term durability. The neck 210, which serves as a connection between the flat member 200 and the dual prongs 300, requires a material that can withstand bending stresses without fatigue. In an exemplary embodiment, a grade of polypropylene (PP) known for its fatigue resistance and resilience could be used, ensuring that the neck 210 maintains its integrity over time. By selecting polymers with these specific grades and characteristics, the ping pong ball retention system 100 will be able to withstand the rigors of regular use while preserving the condition of the ping pong balls 1000 and providing a durable solution for users.

[0054] In association with an exemplary process of manufacturing associated with an embodiment of the invention, the process for the shoe-mountable ping pong ball retention system involves several steps 100, from material selection to final assembly. The process is designed to ensure that each component — the flat member 200, neck 210, and dual prongs 300 — meets the required specifications for durability, flexibility, and adherence to adhesives associated with teachings of the invention.

[0055] The initial stage of manufacturing involves selecting the appropriate material (i.e. the appropriate polymer) based on the desired properties such as resilience, strength, and compatibility with adhesives. Once the material type is chosen, in an exemplary process involving the use of polymers, the material is procured in the form of raw pellets or granules. These pellets are then dried to remove any moisture that could affect the quality of the final product during the molding process.

[0056] The dried polymer pellets are fed into an injection molding machine where they are heated to a molten state. The molten polymer is then injected into precision- engineered molds that define the shape of the flat member 200, neck 210, and dual prongs 300. The molds are designed to ensure that the components have the correct dimensions and structural integrity, with particular attention to the curvature and resilience required for the dual prongs to function effectively.

[0057] After injection, the polymer is allowed to cool and solidify within the mold. Cooling is carefully controlled to prevent warping or the introduction of internal stresses that could compromise the component's performance. Once cooled, the components are ejected from the mold. The ejection system is designed to minimize any potential damage to the components, ensuring that they maintain their precise shape and structural properties.

[0058] The ejected components may require additional post-processing steps in association with various exemplary processes, such as trimming of excess material known as flash, smoothing of edges, or drilling of holes for attachment points. These processes are carried out using automated machinery to maintain consistency and quality across all units.

[0059] The flat member 200, neck 210, and dual prongs 300 are then assembled into the final retention system 100. In an example, following the assembly the hook and loop system is attached to an aspect of the flat member 200. If the design requires, adhesive may be applied to join these components together in association with a contemplated method of manufacture. The type of adhesive used is selected based on its compatibility with the polymer and its ability to form a strong, durable bond. The components are precisely aligned and joined, and the adhesive is allowed to cure according to the manufacturer's specifications.

[0060] In association with an exemplary process of manufacture, throughout the manufacturing process, quality control measures are enacted to ensure that each component and the final assembled product meet the required specifications. This includes dimensional checks, material inspections, and functional tests to verify the retention system's performance.

[0061] In accordance with the preferred method of use of the system 100, the method of retrieving a ping pong ball using the shoe-mountable ping pong ball retention system is designed to enhance the table tennis experience by reducing the physical strain associated with picking up balls 1000 and maintaining the flow of the game of table tennis. The method begins with the user, i.e. the person wearing the shoe 2000 intended for attachment to the system 100, attaching the retention system 100 to an exterior aspect of their shoe 2000. This is achieved in association with the preferred embodiment by aligning the first hook and loop fastener piece 205 on the flat member 200 of the retention system 100 with a corresponding second hook and loop fastener piece 206 on the shoe 2000. The user then presses the two pieces together to form a secure attachment of the system 100 to the shoe 2000 that will withstand the movements involved in table tennis play.

[0062] Once the retention system 100 is securely attached to the shoe 2000, the user positions their shoe 2000 next to a ping pong ball 1000 on a flat surface, as depicted in Fig. 6 A. The dual prongs 300 of the retention system 100 are oriented such that they are substantially above the ping pong ball 1000 in association with this step. The user then steps down with the shoe 2000 with the system 100 aligned over the ping pong ball 1000, applying sufficient downward pressure to force the dual prongs 300 down upon the ping pong ball 1000. The dual prongs 300 resiliently deform and conform to the shape of the ball 1000, securing it in place between them. This step is critical as it ensures that the ball 1000 is retained by the system 100 without the need for bending over or manual picking.

[0063] After the ball 1000 is secured, the user bends the knee of the leg wearing the shoe, raising the shoe 2000 and the retention system 100 towards their hand, as depicted by Fig. 6B. This action brings the retained ping pong ball 1000 to a convenient height for the user to grasp without the need to bend over at the waist, thereby accommodating players with physical limitations or those seeking to avoid back strain. The user can then remove the ping pong ball 1000 from the retention system 100 by applying a gentle force to release the ball 1000 from the grip of the dual prongs 300. This is typically done by using the thumb and fingers to slightly squeeze the ball 300, which allows the ball 1000 to be easily extracted and placed back into play.

[0064] The retention system 100 is particularly useful during table tennis practice sessions, where the frequency of ball retrieval can disrupt the rhythm of play. By utilizing this method, players can quickly and efficiently retrieve balls 1000, minimizing interruptions and maintaining a consistent practice tempo. Additionally, the system is beneficial for individuals with physical limitations, as it enables them to participate in the sport of table tennis without the physical strain of repeatedly bending over to pick up balls. This method not only enhances the accessibility of the sport but also promotes an inclusive environment for all players.
