Abstract
Description
Technical Field
[0001] The present invention relates to technical fields such as elastic materials, thermodynamics, general game kit design and manufacturing processes. Background Art
[0002] In the past few years, the children's toy manufacturing industry has paid increasing attention to safety. This high attention is due to the need to ensure that these products do not pose any risk to children's health during use. Traditional children's toys are usually made of materials such as plastics and rubbers. However, in certain cases, these materials may be doped with plasticizers or other toxic substances, thus bringing potential safety hazards. The use of innovative materials such as shape memory polymers (SMP) has become indispensable for such requirements, thus laying the foundation for non-toxic, safe and attractive children's toys.
[0003] SMP is produced by deforming a material with a first "permanent" configuration and a second "temporary" configuration. When subjected to external stimuli such as heat energy, solvents, electric current, light, magnetic fields, pH value changes and thermal stimuli, the material will return to its initial form. That is to say, the material can "remember" its original shape and return to the original shape after being subjected to external stimuli.
[0004] Such shape memory filaments and fibers can be manufactured by melt spinning, wet spinning and dry spinning methods. In such smart fibers, the shape memory function can be retained, that is, the deformation can be remembered through a reversible phase and the original shape can be restored when triggered by external stimuli. Since the 1960s, bicomponent filaments and fibers have been developed as a new type of chemical fiber and have been widely exploited. Through this technology, for two different polymers with appropriate viscosities, their compositions can be co-extruded from two separate extruders through a spinneret into a single filament. The cross-section of the filament can be of different styles, including coaxial sleeve / core, eccentric core-sheath sleeve / core, side-by-side, wedge sheath, island / seafoam pattern, depending on the application requirements.
[0005] However, all the long fibers and filaments in the above patent applications are limited to two components, and it is difficult for them to freely convert between linear or curly / helical shapes. Based on the disadvantages of existing shape memory polymers, there is a need to provide a non-toxic shape memory material that can adjust its curly shape under different conditions to provide a safer and healthier gaming experience for children. Summary of the Invention

The instruction manual can be in electronic or paper form. Each elastic copolymer material can be manipulated by an external force from its original shape to form one or more three-dimensional structures and can be reversed back to its original shape by stimulation. The three-dimensional structures include one or more of curls, spirals, loops, waves, and coils.
[0007] In one embodiment, the stimulation is thermal energy radiatively transferred by a medium such as air, water, or other fluid having a temperature equal to or higher than the shape recovery temperature.

[0012] When T rN is below room temperature and T rN+1 is above room temperature, in response to the plurality of elastic copolymer materials being stretched to about 30% to about 300% of their original length and released, the plurality of elastic copolymer materials are changed from the original straight shape to a spiral shape; when heated to a temperature above T rN+1 , the material returns to the original straight shape.
[0013] In one embodiment, one or more three-dimensional structures of the plurality of elastomeric copolymer materials are changed by adjusting the elongation length or the stretching time of the plurality of elastomeric copolymer materials.
[0014] In one embodiment, one or more of curls, helices, loops, waves, and coils have a coil diameter of 0.5 to 10 millimeters and a number of turns per centimeter of 5 to 30.
[0015] In one embodiment, the elongation length ranges from 0.5 - 50 centimeters.
[0016] In one embodiment, the stretching time ranges from 0.1 - 60 seconds.

[0032] The present invention will be described in detail by the following embodiments with reference to the drawings. It should be understood that the specific embodiments provided are for illustrative purposes only and should not be construed in a limiting manner. Those skilled in the art will understand that the invention described herein is subject to changes and modifications other than those specifically described.
[0033] The present invention includes all such variations and modifications. The present invention also includes all the steps and features mentioned or indicated in the specification, whether individually or collectively, and any combination of two or more of all such steps or features. Other aspects and advantages of the present invention will be apparent to those skilled in the art from a review of the following description.
[0034] Reference Figure 1 , the game kit 10 is designed to provide an interactive and dynamic experience for users of all ages. At its core, the kit employs an elastomeric copolymer material 101, each of which can be selectively assembled with a connector 210 and exhibits variability from a linear shape to a structural shape (such as a helical shape) upon external force operation (such as stretching). The uniqueness of the present invention lies in the adoption of advanced shape memory materials, enabling the elastomeric copolymer materials to seamlessly return to their original linear shape when stimulated (such as by thermal energy within a specific temperature range, for example, 38 - 40 °C), thereby further enhancing the possibility of interactive play.
[0035] Accompanying the elastomeric copolymer material 101 are components such as a container 102 designed to hold water, which is one of the media for carrying and dissipating thermal energy stimulation. To ensure precise control, a thermometer 103 is also included, allowing users to fine - tune the water temperature for optimal shape operation of the elastomeric copolymer material. The kit 10 is also equipped with an instruction manual 104, which can be in electronic and / or physical form, to guide users through the various functions of the kit 10 and the shape operation of the elastomeric copolymer material 101.
[0036] After being manipulated into a structural shape, exposing the elastomeric copolymer material 101 to a thermal energy stimulation at a temperature equal to or higher than the shape memory recovery temperature will cause the three - dimensional structure formed by the elastomeric copolymer material 101 to substantially return to its original shape. The medium carrying the thermal energy stimulation can be air, water, gel, or any other fluid capable of enveloping the three - dimensional structure. In various embodiments, users can immerse the shaped elastomeric copolymer material 101 in a container of water at approximately 40 °C, or use a hair dryer, either of which will cause the elastomeric copolymer material 10 to return to its original linear shape.
[0037] To add additional stimulation, the game kit 10 also includes one or more challenge cards 105. Each challenge card 105 presents specific task information, encouraging users to explore the full potential of the shape memory material in an interesting and engaging way.
[0038] In one embodiment, the plurality of elastomeric copolymer materials 101 includes at least two shape memory polymer (SMP-N) components, each of the at least two SMP-N components being at least 1% by total weight, and N being a positive integer starting from 1. For example, N can be 1, 2, 3, 4, 5, etc. The SMP-N components have a shape recovery temperature (T r ) between approximately -50 °C and 100 °C, and the recovery temperatures of two or more different components can be represented as T rN and T rN+ 1.
[0039] In one embodiment, the cross-section of at least two SMP-N components has a side-by-side, eccentric core-sheath, circumferential, or layer-by-layer structure.
[0040] In one embodiment, the plurality of elastomeric copolymer materials includes multi-component shape memory wires, fibers, tubes, or tapes. Each of the at least two shape memory polymer components can be a polyester-based polyurethane shape memory material, a polyether-based polyurethane shape memory material, and other suitable shape memory polymer materials. Preferably, the polyester-based polyurethane shape memory material is a polycaprolactone-based shape memory material.
[0041] In one embodiment, the desired SMP includes but is not limited to Diaplex 2520, 3520, 4520. However, the materials of the SMP are not limited to thermosensitive shape memory polymers, but include other polymers sensitive to other stimuli, such as moisture / water-sensitive shape memory polymers, light-sensitive shape memory polymers, and radiation-sensitive shape memory polymers.
[0042] In one embodiment, the diameter of the wire or fiber is in the range of approximately 0.1 to 2 millimeters.
[0043] In one embodiment, the thickness of the tube or tape is in the range of approximately 0.5 to 1 millimeter.
[0044] In one embodiment, when T rN and T rN+1 are above room temperature and where T rN+1 is greater than T rN , in response to the plurality of elastomeric copolymer materials being elongated to about 30% to about 300% of the original length, the plurality of elastomeric copolymer materials are configured to exhibit a first shape change from the original shape to a thin straight shape. When heated to a temperature above T rN and below T rN+ 1, it is configured to exhibit a second shape change, substantially in a helical shape. When heated to a temperature above T rN+1 , it exhibits a third shape change, substantially returning to the original shape.
[0045] When TrN below room temperature and T rN+1 above room temperature, in response to the plurality of elastomeric copolymer materials being stretched to about 30% to about 300% of their original length and released, the plurality of elastomeric copolymer materials change from an original straight shape to a helical shape; when heated to a temperature of T rN+1 or above, the material returns to its original straight shape.
[0046] In one embodiment, when the at least two SMP-N components are SMP-1 and SMP-2, the SMP-1 and the SMP-2 are co-extruded together at a weight ratio of 1-10:10-1. The T r (T r1 ) of SMP-1 is lower than the T r (T r2 ) of SMP-2, and T r is the melting point or glass transition temperature of SMP-1 and SMP-2. The T r1 of SMP-1 is about -30 °C, and the T r2 of SMP-2 is about 35 °C.
[0047] In one embodiment, the helical shape has a coil diameter of 0.5 to 10 mm and includes 5 to 30 turns per centimeter.
[0048] In another aspect, the present invention also provides a method for preparing the elastomeric copolymer material, the method comprising co-extruding a plurality of components together to form an elastomeric copolymer material. The plurality of components comprise at least two shape memory polymer (SMP-N) components, and each of the at least two SMP-N components is at least 1% of the total weight, and the weight ratio between the at least two SMP-N components is 1:10. N is a positive integer starting from 1, including SMP-1, SMP-2, SMP-3, SMP-4, etc. In the present invention, the number of SMP components is not less than two, and in particular, at least two SMP-N components can potentially be used in the elastomeric copolymer material.
[0049] Turning in detail to the drawings, Figure 2 schematically shows a cross-section of an elastomeric copolymer material composed of at least three shape memory polymers (SMP). These SMPs are co-extruded through a spinneret, a T-die, a side-by-side nozzle or a slot die coater. From left to right, there are listed side-by-side in a thread, eccentric core-sheath in a fiber, circumferential within a tube, and layer-by-layer within a strip. The diameter of the multi-component wire or fiber is in the range of about 0.1 to 2 mm, and the thickness of the multi-component tube or strip is in the range of about 0.5 to 1 mm. The elastomeric copolymer material has the function of various shape changes after being stretched. The amount of shape change after stretching depends on the amount of SMP components in the elastomeric copolymer material.
[0050] In one embodiment, the SMP has a glass transition temperature (T r ) and / or a melting temperature (T g ) that serves as the shape recovery temperature (T m ) of the SMP. The T r of all SMP-N components is approximately between -50 and 100 °C.
[0051] The elastomeric copolymer material can be stretched and at least partially fixed in an elongated shape to change from the original shape to the first shape. After stretching under normal conditions, subsequent stimulation of the first shape changes the first shape to a second helical shape. Finally, when the elastomeric copolymer material in the second shape is triggered by stimulation, it causes the shape to change from the second shape to a third linear shape, equivalent to the original shape. This phenomenon is caused by the deformation of the entire structure including the elastomer and crystal compartments during the stretching process. However, when the force is released, only the elastomer part rebounds, causing the material to form curls (see Figure 3 ). When heated, the deformed crystal compartment melts, releasing stress and causing the material to return to its original shape.
[0052] Reference Figure 4 , in one embodiment, when two thermosensitive SMP components SMP-1 and SMP-2 are used in a multi-component filament, they exhibit stimuli that regulate multi-shape changes after stretching. Both SMP-1 and SMP-2 can provide pseudoplasticity at temperatures below the T r of the SMP. For example, T r1 is below room temperature and T r2 is above room temperature. The longer the filament is repeatedly pulled and released at room temperature, the denser the resulting helical structure is in terms of the number of turns. After stretching and releasing at room temperature, the pseudoplasticity on the SMP-2 side tends to maintain elongation, resulting in an instantaneously formed curly shape. If heated above T r2 , the pseudoplasticity of SMP-2 will be removed and the original linear shape will be restored. Heating can be achieved by immersing the filament in water at 40 °C or using a hair dryer with a lower hot air setting.
[0053] In the case of different stimulation modes, the first stimulation of the SMP-1 component can cause a first shape change, and the second stimulation of the SMP-2 component can cause a second shape change. The stimulation can be selected from temperature, humidity / water, light, pH, and radiation. T r1 is above room temperature and below T r2 . Stretching the filament to an elongation of 30 - 30% at room temperature can produce a thin straight shape, and subsequent heating to T r1 can produce a curly / helical shape. If continuously heated above T r2 , the shape can be restored from the curly / helical shape to the original straight shape.
[0054] The following examples illustrate the present invention and are not intended to limit the present invention.
[0055] Example
[0056] Example 1 - Preparation of an elastic copolymer material
[0057] Two SMP-N components can potentially be used in the elastomeric copolymer material. Both the SMP-1 and SMP-2 components account for at least 1% of the total weight and are co-extruded in a weight ratio of 1:1 using an eccentric nozzle. In this example, SMP-1 uses thermoplastic polyurethane elastomer and SMP-2 uses shape memory polyurethane. T r1 is -30 °C, and T r2 is 35 °C. Before processing, all the pellets must be dried at 104 °C for 2 - 4 hours. The barrel temperature of the extruder is 180 - 195 °C (zone 1), 185 - 200 °C (zone 2), 190 - 205 °C (zone 3), and 190 - 200 °C (die zone). The screw speed is 180 - 200 revolutions per minute. Next, without any stretching process, the extruded filaments from the nozzle are cooled in cold water at 15 °C.
[0058] Stretching the elastomeric copolymer material to an elongation of 30 - 300% at room temperature can produce a curly / helical shape, and subsequently heating to 40 °C can produce a straight shape.
[0059] Example 2 - Application of a shape - memory polymer - based game set
[0060] In the kit, there are at least 8 task cards, and each task card lists a specific structure of the elastomeric copolymer filaments that the user needs to create ( Figures 5A - 5G ). In this example, the process of generating the shapes specified by the various task cards in the provided invention kit is outlined.
[0061] In Challenge 1, the goal is to generate a helical structure with a helix diameter of 2 mm. By extending the duration of stretching the shape memory wire, the degree of deformation of the shape memory wire becomes more obvious. Therefore, a longer stretch results in a more complete deformation, thus forming a helical shape with a smaller helix diameter.
[0062] In Challenge 2, the aim is to produce a helical structure with a diameter of 10 mm. As mentioned before, the user can reduce the crystal deformation by shortening the duration of stretching the shape memory wire, which in turn leads to a helical structure with a larger diameter.
[0063] In Challenge 3, the goal is to produce a helical structure on the same filament with diameters of both 2 mm and 10 mm simultaneously. The method includes stretching the filament with different tightness and duration. The shorter the duration of stretching, the larger the helix diameter, and conversely, the longer the extended duration, the smaller the helix diameter.
[0064] In Challenge 4, the goal is to generate multiple spiral structures with lengths less than 4 cm. Following the instructions of Challenge 1, repeatedly transform multiple filaments into a coiled shape and use connectors to gather all the filaments together.
[0065] In Challenge 5, the goal is to generate multiple spiral structures with lengths of 7 - 11 cm. This is achieved by stretching and elongating only one-third of the filaments to form spiral structures with a diameter of 2 mm at the ends of the filaments.
[0066] In Challenge 6, the goal is to create a line segment with the same bending direction and exceeding 15 mm. The user needs to twist the filament during the stretching process. The bending direction can be clockwise or counterclockwise and can be adjusted manually.
[0067] In Challenge 7, there are no restrictions on the number and shape of the filaments, allowing users to make creative and unrestricted designs.
[0068] Example 3 - Other applications of a shape - memory polymer - based set
[0069] Turning Figure 6A , the kit of the present invention extends its versatility by potentially combining one or more building blocks (e.g., Lego bricks). The elastic copolymer materials provided in the kit can be skillfully assembled onto Lego bricks, resulting in visually novel and innovative designs. For example, these elastic copolymer materials are applied in Lego creations and can serve as integral components of various designs, such as imitating animal hair / tails, the hands and feet of dolls, fountains, jellyfish tentacles, decorative bouquets, leaves, etc. The flexibility of the elastic copolymer materials allows users to unleash their creativity and bring a unique touch to their Lego structures.
[0070] It can also be applied to other toys, including the hair of dolls (see Figure 6B ), skipping ropes, spring toys, and parts of toy cars, etc.
[0071] In addition to toys, the kit can be further applied to other designs, such as decorations, artworks, clothing, household items, or product surface designs, or other creative projects.
