Description

Technology Field

[0001] The present invention relates to a device for manufacturing personalized splints, and more specifically, to a device for manufacturing personalized splints that includes a configuration enabling precise molding of a molding object. Background Technology

[0002] Conventional splints are manufactured to perform fixation and support functions tailored to the shape of the user's arms, legs, or joints; however, in actual clinical practice, standardized off-the-shelf splints are generally modified by cutting or heating them. This method makes it difficult to precisely reflect the individual user's body shape and presents problems such as pressure imbalance or localized pain when worn.

[0003] Conventional methods for manufacturing customized splints rely heavily on the experience and tactile senses of skilled workers. Workers estimate the shape of the splint by visually inspecting or physically touching the user's body shape, and then perform molding; this process involves repetitive heating and manual deformation. This manual-centered production method leads to quality variations among workers and presents the problem of difficulty in repeatedly producing splints under identical conditions.

[0004] Recently, technology has been proposed to acquire digital data of a user's body shape using a 3D scanner and to manufacture splints based on this data. However, even with this technology, manual intervention is still required during the post-processing of scan data, conversion of molding data, and the actual material molding process. In particular, for thermoplastic materials, shape stability varies significantly depending on heating temperature, molding time, and cooling conditions, making skilled judgment essential.

[0005] Conventional splint forming processes are often carried out in environments where temperature control is not precise. If the temperature distribution inside the heating equipment is uneven or if it is affected by the external environment, forming results can vary even with the same material. This instability in the temperature environment leads to problems such as variations in splint thickness, localized sagging, and reduced shape retention.

[0006] Furthermore, in conventional technology, structures that induce the natural formation of curves by gravity or external forces during the molding of splint materials have not been sufficiently considered. In most cases, molding is performed by forcibly pressing using flat plates or simple curved jigs, which results in slight discrepancies with the user's body curvature. These differences lead to reduced comfort and discomfort during prolonged wear.

[0007] Conventional technology also has limitations in terms of the efficiency of the splint manufacturing process. Since separate measurement, heating, molding, cooling, and finishing processes must be repeated for each individual user, production time is prolonged, and it is difficult to manufacture multiple splints simultaneously. As a result, the provision of customized splints in medical institutions and rehabilitation centers is currently limited.

[0008] Conventional splint manufacturing processes often fail to adequately consider the generation of hazardous gases. Volatile gases and odors produced during the heating of thermoplastic materials degrade the working environment and pose a risk of health problems with prolonged exposure. However, it is rare to find splint manufacturing equipment that incorporates purification structures to systematically address these issues.

[0009] In terms of control systems, conventional technology often relies on simple on / off control or manual operation. Systems that automatically derive molding conditions based on the user's physical condition or target molding shape and control them precisely are applied only to a limited extent. As a result, the reproducibility of molding quality is low, and data-driven process improvement is difficult to achieve.

[0010] The reality of such conventional technology leads to increased splint production costs. The input of skilled labor, long working hours, and low productivity are ultimately reflected in higher final product prices, which in turn leads to increased burdens on patients and medical institutions. These structural limitations are particularly pronounced in environments requiring mass production and rapid supply.

[0011] Therefore, conventional technology clearly reveals technical limitations in accurately reflecting the user's body structure, stably controlling the molding environment, reducing dependence on operator skill, and efficiently producing a large number of splints simultaneously. To solve these problems of conventional technology, the present invention aims to simultaneously improve precision, reproducibility, and productivity by providing a personalized splint manufacturing device that organically combines a molding object mounting structure, a lifting drive structure, and a control structure.

[0013] Conventional splint manufacturing relies on the experience and manual labor of skilled workers, making it difficult to accurately reflect the user's body structure and resulting in problems such as excessive production time and cost. Furthermore, it is difficult to precisely control the molding temperature and shape, leading to low quality reproducibility and limitations in manufacturing multiple splints simultaneously. To solve these problems, the present invention aims to provide a personalized splint manufacturing device capable of rapid custom production and mass production by molding a disc-shaped splint material into a natural curvature in a stable temperature environment and precisely controlling the molding shape and process. means of solving the problem

[0014] A personalized splint manufacturing device according to one aspect of the present invention for achieving such an objective may comprise: a molding object mounting unit that mounts disc-shaped splint materials composed of thermoplastic plastic materials at spaced intervals and creates a temperature environment in which the disc-shaped splint materials can be molded by naturally forming a curve along a molding guide sphere due to their own weight; a lifting drive unit mounted inside the molding object mounting unit, arranged in multiple units at the location where the disc-shaped splint materials are mounted, and structured to change the position of the disc-shaped splint materials by driving upward, and equipped with an air cylinder unit to drive upward and downward precisely by a control signal transmitted from a molding control unit, and having a molding guide sphere of the shape to be molded mounted on the upper part that contacts the disc-shaped splint materials; and a molding control unit that receives an input signal from an operator to control the operation of the molding object mounting unit and the lifting drive unit, controls the temperature environment of the molding object mounting unit, and controls the upward and downward driving of the lifting drive unit.

[0015] In one embodiment of the present invention, the molding object mounting portion may comprise: a box-shaped structure in which a plurality of mounting grooves capable of mounting the disc-shaped splint material are spaced apart at regular intervals and arranged in a square matrix form, forming an independent space isolated from the external environment, and a splint material mounting main body portion that forms a space capable of maintaining a temperature environment in which the disc-shaped splint material can be molded by a temperature environment creating portion; a temperature environment creating portion that is mounted on the splint material mounting main body portion and has a structure that maintains the temperature inside the space formed by the splint material mounting main body portion, and operates by a control signal transmitted from a molding control portion; and a harmful gas purification portion that is mounted on the splint material mounting main body portion and purifies harmful gases generated inside the space formed by the splint material mounting main body portion and exhausts the purified air to the outside.

[0016] In one embodiment of the present invention, the lifting drive unit may comprise: an air cylinder unit that is mounted at a predetermined interval inside the splint material mounting body and is mounted to be driven independently at the same position as the mounting groove on which the disc-shaped splint material is mounted, driven by air pressure supplied from the outside, and operates by a control signal transmitted from a molding control unit to pull the lifting rod upward or insert it downward; a lifting rod that is mounted on the air cylinder unit and has a structure that moves up and down, and has a structure that mounts a molding guide sphere on its upper end; and a molding guide sphere that is mounted on the upper end of the lifting rod in a detachable structure, has a spherical structure having a shape to be molded, and is mounted on the upper end of a plurality of lifting rods having different outer diameters and different curved surface shapes.

[0017] In one embodiment of the present invention, the molding control unit may comprise: a target molding value input unit that receives molding target information including the user's physical condition, the splint application area, and the required degree of curvature, and provides this information as reference data for subsequent control calculations; an optimal molding environment derivation unit that calculates preset environmental conditions to be applied to the actual molding process based on the molding target information input through the target molding value input unit; a temperature environment control unit that controls the temperature inside the molding target mounting unit by applying temperature-related control parameters calculated by the optimal molding environment derivation unit to an actual temperature environment creation unit; and a lifting drive control unit that directly manages the molding depth and the timing of curvature formation of the disc-shaped splint material by precisely controlling the operation of the lifting drive unit.

[0018] The present invention may also provide a method for manufacturing a personalized splint using the personalized splint manufacturing device described above. A method for manufacturing a personalized splint according to one aspect of the present invention comprises: a target molding value input step for defining the shape and functional requirements of the splint to be finally formed as quantitative data; an optimal molding environment derivation step for converting the molding criteria defined in the target molding value input step into a control environment applicable to an actual process; a temperature environment control step for implementing temperature-related parameters calculated in the optimal molding environment derivation step into the internal space of the actual molding target mounting part to control the disc-shaped splint material to maintain a uniformly softened state suitable for molding; a lifting drive control step for driving a molding guide sphere in an up-and-down direction by controlling an air cylinder unit and a lifting rod of a lifting drive unit to mold the softened disc-shaped splint material into a target shape; and a result product review step for comprehensively verifying whether the splint formed through the lifting drive control step conforms to the target molding value. The configuration may include an optimal control feedback step that corrects control conditions throughout the molding process and reflects them in the next manufacturing process based on evaluation results derived from the above result product review step. Effects of the invention

[0019] The personalized splint manufacturing device according to the present invention organically combines a molding object mounting unit, a lifting drive unit, and a molding control unit, thereby inducing a disc-shaped splint material to naturally bend along a molding guide sphere due to its own weight. Accordingly, it is possible to manufacture a splint that more precisely reflects the user's body curvature, and the uniformity and reproducibility of molding quality are improved. Furthermore, by automatically controlling the temperature environment and lifting drive, dependence on the operator's skill level is reduced, and multiple splints can be manufactured rapidly simultaneously. Moreover, by shortening production time and improving process efficiency, manufacturing costs and unit prices can be reduced, and customized splints that immediately reflect various physical conditions and requirements can be reliably provided.

[0024] Referring to these drawings, the personalized splint manufacturing device (100) according to the present embodiment is equipped with a molding object mounting part (110) of a specific structure, a lifting drive part (120), and a molding control part (130), thereby enabling rapid production of splints of various sizes customized to the user's body structure, as well as mass production within a short period of time, significantly reducing production costs and sales unit prices, and providing a personalized splint manufacturing device that includes a configuration capable of immediately reflecting the user's specific physical condition and requirements.

[0025] Hereinafter, with reference to FIGS. 1 to 3, each component constituting the personalized splint manufacturing device (100) according to the present embodiment will be described in detail.

[0026] Detailed description of the mounting part (110) of the molding object

[0027] The molding object mounting section (110) is a core structure that enables the molding process to be carried out while stably supporting the disc-shaped splint material, and plays a role that determines the precision and reproducibility of the splint molding. The molding object mounting section (110) is configured to mount multiple disc-shaped splint materials spaced apart at regular intervals, providing conditions that allow each splint material to be molded independently without mutual interference. This spaced arrangement serves as a basis for maintaining uniform heat distribution and deformation behavior even during the process of molding multiple splint materials simultaneously.

[0028] The molding target mounting portion (110) is designed so that the disc-shaped splint material naturally descends due to its own weight, allowing a curve to be formed along the molding guide sphere. Unlike conventional forced compression methods, this structure induces the formation of a natural curvature without applying unnecessary external force to the splint material, thereby minimizing internal stress concentration and improving shape stability after molding. As a result, it becomes possible to mold a splint that more accurately reflects the curvature of the user's body.

[0029] The molding target holder (110) includes a function to create and maintain a temperature environment suitable for molding, thereby enabling stable control of changes in the physical properties of the thermoplastic plastic material. As a constant temperature is maintained while the splint material is being molded, the degree of softening of the material is uniformly ensured, and localized overheating or incomplete molding is prevented. This acts as a factor that structurally improves the molding deviations that were pointed out as problems in the prior art.

[0030] In addition, the molding object mounting section (110) is designed based on a precise positional correspondence with the lifting drive section. By arranging the position where the disc-shaped splint material is mounted and the position where the molding guide sphere of the lifting drive section rises to exactly coincide, positional error during molding is minimized. This alignment structure ensures that the same result can always be obtained even in a repetitive molding process based on automatic control.

[0031] The molding object mounting section (110) is implemented with a structure that simultaneously considers the productivity and safety of the entire device. By forming a space isolated from the external environment while simultaneously accommodating multiple splint materials, access by workers is minimized and risk factors that may occur during molding are reduced. Accordingly, the efficiency of the molding process and the safety of the working environment are improved together.

[0032] Detailed description of the main body (111) with the splint material

[0033] The splint material mounting body (111) is the central structure of the molding object mounting part (110) and provides a space where the disc-shaped splint material is actually placed and a molding environment is formed. The splint material mounting body (111) is formed in a box-shaped structure to block external airflow and heat changes, and secure an independent molding space inside. This sealed structure plays an important role in maintaining stable molding conditions.

[0034] Inside the main body (111) for supporting splint materials, a plurality of mounting grooves capable of accommodating disc-shaped splint materials are arranged at regular intervals. The mounting grooves are arranged in a square matrix shape to maximize space utilization and guide each splint material to be arranged at uniform intervals. This arrangement structure contributes to maintaining uniform heat distribution and molding conditions even during the process of molding multiple splint materials simultaneously.

[0035] The splint material mounting body (111) is combined with the temperature environment creation unit and performs the function of maintaining an internal temperature optimized for molding. By maintaining a uniform temperature state throughout the entire internal space, the timing and degree of softening of the splint material can be precisely controlled. This resolves the problem of non-uniformity in molding timing that occurred in conventional technology and has the effect of increasing the reproducibility of molding quality.

[0036] The splint material mounting body (111) is designed so as not to spread gas or odors generated during the molding process to the outside. Since harmful gases generated in the internal space are processed in conjunction with a purification unit, the operator can operate the device in a pleasant environment. This structure fundamentally improves the problem of deterioration of the working environment that occurred in conventional open-type heating methods.

[0037] The splint material mounting body (111) is made of a material that ensures heat resistance and structural strength, taking into account long-term repeated use. It is designed so that no deformation or performance degradation occurs even in an environment where molding temperatures are repeatedly applied, and it can have a structure that is easy to maintain and clean. Accordingly, the reliability and lifespan of the device are improved, and a stable splint manufacturing process is continuously maintained.

[0038] Detailed explanation of the temperature environment composition part (112)

[0039] The temperature environment creation unit (112) is a key component for rapidly bringing the internal space formed by the splint material mounting body (111) to a target temperature range and maintaining it stably while minimizing temperature deviations throughout the molding process. Since the viscoelastic behavior of the disc-shaped splint material made of thermoplastic plastic changes rapidly in the softening temperature range, the temperature environment creation unit (112) performs the role of precisely forming the thermal conditions of the internal air and inner wall so that the material has a uniform softening state. This allows for structural suppression of defect factors such as localized overheating, unsoftened areas, and restoration deformation after molding that occurred in conventional simple heating methods.

[0040] The temperature environment creation section (112) can be implemented in a form that considers both the arrangement of heat sources and the heat diffusion structure to make the heat distribution in the internal space uniform. For example, a planar heating element may be distributed along the inner wall of the splint material mounting body section (111), or a structure may be adopted in which a heating unit is placed on the lower side and hot air circulating upwards is induced. At this time, the temperature environment creation section (112) may include mechanical elements such as guide ducts, flow guides, and heat diffusion plates to reduce the stagnant area of ​​internal air and alleviate heat stratification, thereby ensuring similar molding conditions throughout the entire section of the matrix-arranged mounting groove.

[0041] Since the temperature environment creation unit (112) operates by a control signal transmitted from the molding control unit (130), it can be configured to implement a temperature profile for each stage of the molding process, not just simple heating. Depending on the target molding value, it can be operated in a manner that performs rapid heating in the preheating section, maintains a constant temperature in the molding section, and provides a gradual cooling or stabilization section after molding. This temperature profile-based operation is advantageous for precisely aligning the start time of material softening with the time of bend formation induced by the molding guide sphere, and has the effect of increasing the reproducibility of molding quality.

[0042] The temperature environment creation unit (112) provides particularly significant effects in an operating environment where multiple disc-shaped splint materials are molded simultaneously. Since the thickness of the material, initial temperature, and surrounding flow conditions may vary slightly at each mounting groove position arranged in a matrix form, the temperature environment creation unit (112) can subdivide the control unit to absorb these differences. For example, it is possible to divide the internal space of the splint material mounting body (111) into multiple zones and independently control the heat output for each zone, or to finely adjust the heat source output based on internal temperature sensor signals. By introducing a zone control structure in this way, problems such as delayed molding or excessive softening at specific locations can be prevented.

[0043] The temperature environment creation section (112) can be configured with a structure that takes into account heat resistance stability and maintainability. Since a high temperature state is repeatedly formed in the internal space, the heating element fixing structure can be appropriately designed with fastening and insulating sections so that deformation or detachment due to thermal expansion does not occur. In addition, the temperature environment creation section (112) can be configured with a protective cover around the heat source or a panel structure on the inner wall surface that can be washed, taking into account internal contaminants or fine residues generated from the splint material. Such a design contributes to reducing fluctuations in molding conditions during long-term operation of the device and maintaining a stable splint manufacturing process.

[0044] Detailed explanation of the harmful gas purification unit (113)

[0045] The harmful gas purification unit (113) is configured to purify volatile gases, odor components, fine particles, etc., that may be generated during the process of heating and softening the thermoplastic plastic material inside the splint material mounting body (111), and then exhaust them to the outside. In conventional technology, there was a problem where odors remained in the workspace or workers were exposed for a long time because there was a reliance on open heating or simple ventilation. The harmful gas purification unit (113) structurally improves these work environment problems, providing safety and comfort that allow the device to be continuously operated in medical institutions or production facilities.

[0046] The harmful gas purification unit (113) can be implemented in a form that includes an intake path for collecting gas generated in the internal space and a purification path for purifying the collected gas. For example, an intake port may be formed on the upper or side of the splint material mounting body (111), and a flow path may be guided so that the flow of internal air passes through the entire area of ​​the mounting groove. In this case, the harmful gas purification unit (113) may not be a structure that simply sucks in gas, but may include flow design elements that stabilize the internal air flow to prevent gas from stagnating in a specific area, thereby preventing odor concentration or local contamination.

[0047] The purification method of the harmful gas purification unit (113) can adopt a filter and adsorption structure suitable for the actual operating environment. An activated carbon adsorption filter can effectively reduce volatile organic compounds and odor components, and a multi-stage structure can be applied in which fine particles are first removed through a pre-filter and then guided to the adsorption filter. In addition, considering irritating gas components that may be generated from specific materials, it is also possible to add a catalyst-based deodorizing layer or a chemical neutralization layer. Such a multi-stage purification structure is advantageous for extending filter life and stabilizing purification performance.

[0048] The harmful gas purification unit (113) is linked with the molding control unit (130) to precisely control operating conditions. Since the amount of gas generated may increase during the heating stage of the temperature environment creation unit (112), it is possible to increase the suction flow rate and switch to low-noise operation during the stabilization stage. Additionally, the structure can be expanded to determine the filter replacement time based on changes in filter differential pressure or flow rate and provide an inspection alarm to the operator. Unlike conventional manual ventilation methods, such control linkage provides the effect of continuously maintaining safety while reducing the burden on the operator.

[0049] The harmful gas purification unit (113) can be installed considering the direction and quality of the air exhausted to the outside. The exhaust line can include a backflow prevention structure to prevent external air from entering the interior or unpurified air from leaking out of the device. In addition, the purification unit housing can be formed with a sealed coupling structure to reduce leakage around the filter and adopt a sliding coupling or hinge opening / closing structure to facilitate easy replacement of the filter cartridge. This structure contributes to simultaneously satisfying the hygiene and ease of maintenance required in medical or workplace environments.

[0050] Detailed description of the elevator drive unit (120)

[0051] The lifting drive unit (120) is a core drive structure that is positioned inside the molding target mounting unit (110) and directly determines the molding shape by precisely controlling the position of the disc-shaped splint material in the up and down direction. The lifting drive unit (120) is arranged in multiple units to correspond to each of the multiple disc-shaped splint materials, thereby providing a parallel drive environment in which multiple splints can be molded simultaneously within a single device. This structure serves as a basis for dramatically improving productivity, unlike the method of molding one by one in the prior art.

[0052] The lifting drive unit (120) is installed to correspond precisely to the position of the seating groove formed in the molding target mounting unit (110), thereby enabling precise position control for the center of the disc-shaped splint material or a set molding point. When the lifting drive unit (120) is driven upward, the molding guide sphere approaches the splint material from the bottom upward, and the splint material forms a natural curve due to its own weight and the curved shape of the guide sphere. This upward support method is advantageous for preventing local stress concentration caused by forced compression.

[0053] The lifting drive unit (120) is based on a structure capable of precisely controlling the lifting speed, lifting position, stopping time, and lowering point according to the control signal of the molding control unit (130). By inducing deformation of the material through a gradual rise during the initial stage of molding and controlling it to maintain a certain position during the target molding section, the stabilization of the molded shape can be achieved. This control method structurally solves the problem of controlling the molding depth, which in conventional technology relied on the operator's hand sense.

[0054] The lifting drive unit (120) can be designed to selectively mount multiple molding guide spheres with different outer diameters and curved shapes. Accordingly, different molding conditions can be applied according to the user's body part, size, and degree of curvature even within the same device, and various customized splints can be produced without replacing the device. This has the effect of resolving the inconvenience of having to replace separate jigs or tools in the prior art.

[0055] The lifting drive unit (120) is implemented in a form that takes into account structural strength and durability so that it can operate stably in repetitive lifting movements and high-temperature environments. The lifting guide, support frame, and fastening structure can be designed so that no play or deformation occurs even during long-term operation, and can be modularized so that inspection and replacement are possible on an individual drive unit basis during maintenance. This configuration contributes to ensuring the reliability and long-term operational stability of the device.

[0056] Detailed description of the air cylinder unit (121)

[0057] The air cylinder unit (121) serves as a power source that provides the actual driving force for the lifting drive unit (120), and performs the function of pulling the lifting rod (122) upward or inserting it downward using air pressure supplied from the outside. The air cylinder unit (121) has a simpler structure and faster response speed compared to an electric drive method, and can maintain stable driving characteristics even in a high-temperature environment, making it suitable for the splint forming process.

[0058] The air cylinder unit (121) is arranged in multiple units at regular intervals inside the molding object mounting section (110), configured to enable independent lifting control for each disc-shaped splint material. This independent driving structure provides flexibility to selectively mold only specific splint materials or to simultaneously achieve different molding depths and curvatures. This overcomes the limitations of the conventional method of controlling the entire system with a single driving unit.

[0059] The air cylinder unit (121) can be configured to control the air pressure supply and discharge amounts according to the control signal of the molding control unit (130). This allows for fine adjustment of the lifting speed or control to maintain a stopped state at a specific position. This pneumatic control-based lifting method is advantageous for mitigating the impact at the moment the molding guide ball contacts the splint material and for preventing material damage.

[0060] The air cylinder unit (121) may have a structure that ensures the durability of the cylinder inner wall, piston, and sealing part by taking into account friction and wear caused by repeated driving. In addition, a sealing structure to prevent air leakage and a guide structure to reduce minute driving errors may be applied together. This design improves the reproducibility of the lifting position and contributes to maintaining molding precision even during long-term use.

[0061] The air cylinder unit (121) can be installed in a manner that considers maintenance and safety. The air pressure supply line can be easily replaced through a detachable connector structure and may include a safety valve structure that automatically shuts off when abnormal pressure occurs. This prevents unexpected operating malfunctions or safety accidents during device operation and improves reliability and management efficiency compared to conventional technology.

[0062] Detailed description of the lifting rod (122)

[0063] The lifting rod (122) is a core transmission member that receives the driving force of the air cylinder unit (121) directly and moves in the up-and-down direction to precisely position the molding guide sphere (123). The lifting rod (122) is positioned vertically to align with the internal structure of the molding object mounting part (110) and is designed to correspond precisely to the center of the position where the disc-shaped splint material is mounted or to a set molding point. This structure minimizes positional error during molding and ensures that the same reference point is always maintained even during repeated molding processes.

[0064] The lifting rod (122) is implemented in a form that secures sufficient rigidity and straightness to stably support the load and forming reaction force generated during the lifting process. In particular, since resistance is generated due to the formation of a curve during the process of pushing the splint material upward through the forming guide body (123), the cross-sectional structure and material of the lifting rod (122) are considered so that bending or twisting does not occur. Accordingly, the problem of the forming depth and curvature deviating from the intended values ​​can be prevented.

[0065] The lifting rod (122) is designed so that play is minimized at the connection point with the air cylinder unit (121). The connection point between the drive shaft and the lifting rod (122) may have a precision-machined connection structure to prevent wear accumulation even with repetitive reciprocating motion, and a guide bushing or sleeve structure may be applied as needed. This connection stability contributes to increasing the reproducibility of the lifting position and maintaining the uniformity of the molding quality.

[0066] The lifting rod (122) may be made of a material that ensures heat resistance and corrosion resistance, taking into account the internal environment of the molding object mounting part (110). Since fine gases or residues may be present along with a high-temperature environment during the molding process, the surface of the lifting rod (122) may be treated to minimize contamination adhesion. This has the effect of preventing increased driving resistance or malfunction during long-term operation.

[0067] The lifting rod (122) is configured to allow a molding guide sphere (123) to be detachably mounted on its upper portion. This allows for the selective application of molding guide spheres (123) of different shapes depending on the intended use or the body part to be molded, and enables the production of various customized splints without modifying the entire device. This structure serves as a factor that expands the range of application of the device and improves operational flexibility.

[0068] Detailed description of the molding guide sphere (123)

[0069] The forming guide sphere (123) is a core forming member mounted on the upper end of the lifting rod (122) to support the lower part of the disc-shaped splint material and to guide the splint material to naturally bend due to its own weight. The forming guide sphere (123) has a structure in which the entire curved surface is smoothly connected based on a spherical shape, thereby preventing localized pressure from concentrating on the splint material. Accordingly, material damage or surface deformation is suppressed during forming.

[0070] The molding guide sphere (123) can be provided in various shapes having different outer diameters and radii of curvature. This reflects the fact that the required curvature varies depending on the user's body part, body type, and molding purpose, and various customized splint moldings are possible by replacing the molding guide sphere (123) mounted on the lifting rod (122). This configuration structurally solves the problem of requiring jig replacement or manual modification in the prior art.

[0071] Since the surface of the molding guide sphere (123) comes into direct contact with the splint material, friction characteristics and surface condition have a significant impact on the molding quality. Accordingly, the surface of the molding guide sphere (123) may be processed to be smooth, or a low-friction coating may be applied as needed. Due to this surface treatment, the material is prevented from getting stuck or torn during the molding process, and the surface quality is improved after molding.

[0072] The molding guide sphere (123) can be made of a heat-resistant material to ensure shape stability even in a high-temperature environment. It is designed so that no change in outer diameter or surface deformation occurs during the molding process involving repeated heating and cooling, thereby maintaining the same molding results even during long-term use. This is an important factor in increasing the reproducibility and reliability of the molding process.

[0073] The molding guide sphere (123) is configured to facilitate maintenance and management through a detachable structure. If contamination occurs during the molding process or if it is necessary to replace a molding guide sphere (123) of a specific shape, it can be quickly detached and mounted without the need for separate tools. This structure provides the effect of minimizing device downtime and enabling immediate response to various molding requirements.

[0074] Detailed description of the molding control unit (130)

[0075] The molding control unit (130) serves as a central component that integrally controls the operation of the entire personalized splint manufacturing device and performs the role of organically linking the operation of the molding object mounting unit (110), the lifting drive unit (120), the temperature environment creation unit (112), and the harmful gas purification unit (113). The molding control unit (130) is not merely a driving signal output device, but functions as a control hub that comprehensively judges and adjusts the molding environment and driving conditions based on the target molding result. Through this, control elements that were dispersed in conventional technology can be integrated into a single system.

[0076] The molding control unit (130) manages the flow of the entire molding process based on user input information and device internal status information. It comprehensively collects information such as the internal temperature status of the molding object mounting unit (110), the current position of the lifting drive unit (120), and the driving status of each air cylinder unit (121), and generates control commands for the next stage based on this information. This closed-loop control structure enables immediate correction of deviations that may occur during the molding process, thereby increasing the stability of the molding result.

[0077] The molding control unit (130) is configured to apply different control strategies for each stage of the molding process. In the preheating stage, the heating output of the temperature environment creation unit (112) is intensively controlled to quickly reach the target temperature, and in the molding stage, the lifting speed and stopping position of the lifting drive unit (120) are precisely adjusted. After molding, temperature stabilization control is performed along with lowering drive to induce the fixation of the splint's shape. Such step-by-step control has the effect of automating process judgments that relied on the operator's experience in conventional technology.

[0078] The molding control unit (130) can independently manage each molding line even in a parallel operation environment where multiple disc-shaped splint materials are molded simultaneously. Since different molding depths, holding times, and temperature conditions can be applied through control channels corresponding to each lifting drive unit (120), it is possible to manufacture splints that reflect different user conditions simultaneously within the same device. This is an important function that resolves the inefficiency of having to repeatedly perform individual molding in the prior art.

[0079] The molding control unit (130) may also include a protection control function to ensure the reliability and safety of the device. When an abnormal situation is detected, such as an overheating state, an abnormal air pressure, or a delay in the response of the drive unit, the molding control unit (130) immediately performs control to limit the drive or stop the process. This prevents damage to the device or molding defects in advance and enables stable operation for a long period of time.

[0080] Detailed explanation of the target molding value input section (131)

[0081] The target molding value input unit (131) is an interface configuration that provides reference information for the molding control unit (130) to perform the molding process, and serves as the starting point for manufacturing a user-customized splint. The target molding value input unit (131) receives molding target information, such as the user's physical condition, the area where the splint is applied, and the required degree of curvature, and uses this information as reference data for subsequent control calculations. This allows for the quantification of molding standards that were previously judged intuitively by the operator in conventional technology.

[0082] The target molding value input section (131) can be configured to accommodate various input methods. For example, it is possible to directly input body dimension data obtained from an external measuring device or to select one of the pre-set standard molding profiles. Additionally, correction values ​​reflecting the wearing strength or support range required by the user can be additionally input. This input flexibility contributes to accommodating a wide range of user conditions.

[0083] Information input through the target molding value input unit (131) is not merely stored but is converted into control parameters that can be interpreted within the molding control unit (130). The input curvature information is converted into the rising position of the lifting drive unit (120) and the selection criteria for the molding guide sphere (123), and the required molding stability is reflected in the holding time of the temperature environment creation unit (112) and the output control conditions. This conversion process is a key element in realizing the automation of the molding process.

[0084] The target molding value input section (131) may have a structure capable of storing and retrieving the input target molding value, taking into account remanufacturing by the same user or repeated manufacturing under similar conditions. Through this, splints under the same conditions can be reproducibly manufactured again, and efficient operation becomes possible when repeated prescriptions are made in medical institutions or rehabilitation facilities. This eliminates the inconvenience of having to set molding conditions anew every time in the prior art.

[0085] The target molding value input unit (131) can be flexibly utilized in conjunction with the molding control unit (130) even during the molding process. If fine adjustments are required during the molding result review stage, a correction value can be entered through the target molding value input unit (131) and immediately reflected in the next molding process. This feedback-based input structure enables active response to changes in user requirements or field conditions and plays a role in further enhancing the completeness of customized splint manufacturing.

[0086] Detailed explanation of the optimal molding environment derivation unit (132)

[0087] The optimal molding environment derivation unit (132) is a core computational component that calculates the optimal environmental conditions to be applied to the actual molding process based on molding target information input through the target molding value input unit (131). The optimal molding environment derivation unit (132) does not merely serve the role of transmitting setting values, but derives the combination of conditions with the highest probability of molding success by comprehensively considering the material characteristics of the splint material, the shape of the molding target, and the internal state of the device. Through this, the problem of setting molding conditions, which was arbitrarily determined by the operator's experience in conventional technology, is structurally improved.

[0088] The optimal molding environment derivation unit (132) performs the function of converting target molding values ​​into control parameters such as temperature, time, lifting position, and holding period. For example, it sets criteria for selecting the outer diameter of the molding guide sphere (123) according to the input curvature or molding depth, and calculates the lifting limit position and holding time of the lifting drive unit (120) suitable for this. At the same time, by considering the softening characteristics of the thermoplastic plastic material and calculating the temperature range and stabilization time suitable for molding, the possibility of molding defects is reduced in advance.

[0089] The optimal molding environment derivation unit (132) can be linked with status information collected in real time within the device. When information such as the internal temperature deviation of the molding object mounting unit (110), previous molding history, and driving response characteristics is reflected, molding conditions can be finely adjusted according to the situation, even if the same target molding value is used. This adaptive computational structure contributes to maintaining uniformity in molding quality even in a repetitive production environment.

[0090] The optimal molding environment derivation unit (132) operates effectively even in a parallel process where multiple splint materials are molded simultaneously. When different target molding values ​​are input for each mounting position, the optimal molding environment derivation unit (132) separates and manages them as individual control sets. Accordingly, different molding conditions can be applied simultaneously in a single device, which has the effect of resolving the time delay problem caused by sequential operations in the prior art.

[0091] The optimal molding environment derivation unit (132) can be expanded into a structure that takes into account the connection with the molding result. Shape errors or user feedback identified during the result product review stage after molding is completed can be reflected in the environment derivation process for the next molding, thereby gradually improving the precision of the molding conditions. This structure enables the present invention to function as a system whose performance is stabilized through repeated operation, going beyond a simple automation device.

[0092] Detailed description of the temperature environment control unit (133)

[0093] The temperature environment control unit (133) is configured to precisely control the temperature inside the molding object mounting unit (110) by applying temperature-related control parameters calculated by the optimal molding environment derivation unit (132) to the actual temperature environment creation unit (112). The temperature environment control unit (133) continuously manages the temperature state at all stages of the molding process, thereby ensuring that the splint material always maintains the intended softening conditions. This is a key element in solving the problem in conventional technology where the molding quality varied due to unstable heating conditions.

[0094] The temperature environment control unit (133) performs closed-loop control based on information transmitted from an internal temperature sensor. If the actual temperature of the internal space deviates from the target temperature range, the temperature environment control unit (133) immediately adjusts the output of the temperature environment composition unit (112) to correct the deviation. This real-time control structure contributes to maintaining a stable molding environment despite changes in the external environment or internal load.

[0095] The temperature environment control unit (133) can apply different control strategies for each stage of the molding process. During the preheating stage, a rapid temperature rise is induced to shorten the molding preparation time, during the molding stage, the target temperature is maintained at a constant level, and after molding is completed, the shape fixation can be stabilized through a gradual temperature reduction. Such step-by-step temperature control implements a process flow optimized for changes in the physical properties of the splint material.

[0096] The temperature environment control unit (133) is designed to maintain uniform temperature conditions even in an environment where multiple splint materials are molded simultaneously. By dividing the internal space of the splint material mounting body (111) into multiple control areas and independently monitoring and adjusting the temperature of each area, the temperature deviation at each location can be minimized. This prevents problems such as molding being delayed or excessive softening occurring only at specific locations.

[0097] The temperature environment control unit (133) may include a protection control function that takes safety and reliability into account. When an overheating condition is detected or a sensor malfunction occurs, the temperature environment control unit (133) performs control to limit the heating output or stop the molding process. This protection control prevents damage to the device and material degradation, and plays an important role in maintaining a stable splint manufacturing process for a long period of time.

[0098] Detailed description of the elevator drive control unit (134)

[0099] The lifting drive control unit (134) is a core control component included in the molding control unit (130) that directly manages the molding depth and the timing of curve formation of the disc-shaped splint material by precisely controlling the operation of the lifting drive unit (120). Beyond a simple driving signal output function, the lifting drive control unit (134) performs the role of coordinating the control flow so that the lifting motion is accurately linked to the molding conditions throughout the molding process. Through this, the problem of controlling the molding depth, which relied on the operator's senses in conventional technology, is structurally resolved.

[0100] The lifting drive control unit (134) determines the lifting start time, lifting speed, target position, and holding time of each lifting drive unit (120) based on the lifting-related control parameters calculated by the optimal molding environment derivation unit (132). For example, by controlling the lifting operation to start at the time when the splint material is sufficiently softened, the molding guide sphere (123) is made to contact the splint material without excessive resistance. This control contributes to preventing molding defects and material damage.

[0101] The lifting drive control unit (134) is configured to control a plurality of air cylinder units (121) individually. Since different lifting positions or holding conditions can be applied through control channels corresponding to each lifting drive unit (120), various molding conditions can be implemented simultaneously within a single device. This overcomes the limitation of having to mold collectively under the same conditions in the prior art and is a factor that enables the manufacture of truly personalized splints.

[0102] The lifting drive control unit (134) may include a function to detect and respond to abnormal conditions that may occur during the lifting operation. When abnormal signs such as a decrease in lifting speed, failure to reach the target position, or fluctuations in air pressure are detected, the lifting drive control unit (134) immediately performs control to limit the drive or stop the molding process. This protective control prevents device damage and molding defects in advance and enables stable process operation.

[0103] The lifting drive control unit (134) can be expanded into a structure that supports continuous process improvement through linkage with the molding results. Molding deviations or user feedback identified during the result product review stage can be reflected in the correction of lifting control parameters in the next molding process, thereby gradually improving the precision of lifting depth and curvature formation. Such a feedback-based control structure enables the lifting drive control unit (134) of the present invention to function as a system that accumulates stability and reliability through repeated operation.

[0104] Below, a method for manufacturing a personalized splint (S100) using a personalized splint manufacturing device (100) is described in detail.

[0105] The method for manufacturing a personalized splint (S100) consists of a series of control procedures to precisely mold the splint according to the user's physical condition and required shape. First, in the target molding value input step (S110), molding standard information such as the user's body dimensions, application area, and required degree of curvature is input and set as the standard value for subsequent processes. Next, in the optimal molding environment derivation step (S120), temperature and lifting conditions suitable for molding are calculated based on the input target molding value, considering the material characteristics of the splint material and the device status. In the temperature environment control step (S130), the temperature inside the mounting part of the object to be molded is precisely controlled according to the calculated conditions to ensure that the splint material maintains a uniform softened state. Subsequently, in the lifting drive control step (S140), the molding guide sphere is driven to lift, naturally bending and molding the softened splint material using its own weight and curved shape. In the result product review step (S150), the shape and quality of the completed splint are checked to determine whether it matches the target molding value. In the optimal control feedback step (S160), control conditions are corrected based on the review results and reflected in the next molding process, thereby continuously improving molding precision and reproducibility even during repeated production.

[0106] Detailed explanation of the target molding value input step (S110)

[0107] The target molding value input step (S110) is the starting point of the personalized splint manufacturing method (S100) and is a step in which the shape and functional requirements of the splint to be finally formed are defined as quantitative data. In this step, information such as the user's body dimensions, the area where the splint is applied, the required range of curvature, and the support strength is input and set as a standard value for the entire molding process. In conventional technology, the operator judged these standards based on visual inspection and experience, but the target molding value input step (S110) ensures objectivity and reproducibility of the molding standards by structuring them based on data.

[0108] The target molding value input step (S110) can be implemented through various input interfaces. For example, body shape data obtained through a 3D scanner or simple measuring equipment can be directly input, and a standard splint shape profile selected by medical staff can be used as a reference value. This input data is not a simple set of numerical values, but is organized and stored as meaningful molding parameters such as molding depth, radius of curvature, and coverage area. Through this, the device can clearly distinguish and recognize different user conditions.

[0109] In the target forming value input step (S110), the validity of the input value can be verified in advance by utilizing rule-based control logic. For example, if a value exceeding the maximum bending range applicable to a specific area or the material property limit is input, logic can be applied to automatically correct it or provide a warning. This rule-based judgment can be implemented using a simple if-then structure and serves to simultaneously enhance the safety of the device and the forming success rate.

[0110] In addition, the target shaping value input step (S110) can be combined with a machine learning-based recommendation function. By applying a regression model or a classification model trained on past shaping history data and user characteristic data, the most suitable target shaping value for the input body condition can be automatically suggested. For example, it is possible to calculate an initial target value by referring to the shaping value of a splint that was previously successfully applied to similar body types and conditions. This has the effect of reducing the setting burden on medical staff or operators.

[0111] The target molding value input step (S110) is not limited to a one-time input but is designed with the premise of linkage with subsequent processes. The input target molding value can be modified or supplemented after reviewing the molding results, and such modification history is accumulated in a database. This enables the rapid and accurate setting of molding standards during remanufacturing for the same user or repeated production under similar conditions, thereby improving the efficiency and consistency of the entire manufacturing process.

[0112] Detailed explanation of the optimal molding environment derivation step (S120)

[0113] The optimal forming environment derivation step (S120) is a key step that converts the forming criteria defined in the target forming value input step (S110) into a control environment applicable to the actual process. In this step, the material characteristics and thickness of the splint material, the structural characteristics of the forming device, and the current state of the device are comprehensively considered to calculate the temperature and lifting conditions most suitable for forming. In this step, forming conditions that were intuitively determined by the operator's experience in conventional technology are systematically derived through logical calculations.

[0114] The optimal molding environment derivation step (S120) can utilize model-based control logic. For example, based on a mathematical model that models the softening characteristics of thermoplastic materials, the minimum softening temperature and holding time required to form a target curvature can be calculated. This model is constructed based on material property data and experimental results, and automatically calculates control parameters according to the input target molding value. This allows for the reduction of the possibility of molding defects in advance.

[0115] In addition, the optimal molding environment derivation step (S120) can be combined with a machine learning-based prediction model. By applying a regression model, support vector machine, or neural network model trained on past molding process data and result quality data, it is possible to predict the combination of temperature and lifting conditions that has the highest success probability for a specific target molding value. This data-driven approach enables the derivation of an environment with high reliability, even in molding processes involving complex interactions.

[0116] The optimal forming environment derivation step (S120) can be extended to an adaptive control structure that reflects real-time device status information. When status information such as internal temperature deviation, response delay in the previous process, and increased friction of the lifting drive unit is input, control conditions can be finely adjusted even for the same target forming value. This can be implemented through reinforcement learning-based control logic, and the optimized forming environment is learned gradually through iterative operation.

[0117] The optimal forming environment derivation step (S120) plays an important role even in a parallel forming environment. When multiple splint materials are formed simultaneously, the target forming values ​​and environmental conditions for each forming position may differ; therefore, they are separated into independent control sets for management. In this process, by applying a clustering algorithm or an optimization algorithm, it is possible to configure an environment that simultaneously satisfies the energy efficiency and forming uniformity of the entire device. Through this structure, the manufacturing method of the present invention can simultaneously achieve high precision and productivity compared to conventional technology.

[0118] Detailed explanation of the temperature environment control step (S130)

[0119] The temperature environment control step (S130) is a step in which temperature-related parameters calculated in the optimal molding environment derivation step (S120) are implemented in the internal space of the actual molding target support part (110) to ensure that the disc-shaped splint material maintains a uniformly softened state suitable for molding. Since the viscoelastic behavior of thermoplastic plastic materials changes rapidly depending on the temperature range, the temperature environment control step (S130) does not merely stop at matching the target temperature, but also performs the role of forming a temperature profile so that the degree of softening of the material is consistent at the time of molding and at the time of lifting operation. Through this, problems such as local sagging due to overheating, insufficient molding due to insufficient softening, and restoration deformation after molding, which frequently occurred in conventional technology, are structurally reduced.

[0120] The temperature environment control step (S130) can be implemented as a sensor-based closed-loop control, and corrects control errors by collecting real-time data from temperature sensors installed at multiple internal locations of the splint material mounting body (111). For example, the heating output and internal air circulation volume can be finely adjusted by applying a PID control logic that utilizes the deviation of the current temperature from the target temperature. In addition, since simple PID control may cause overshoot due to thermal delay and thermal inertia, feedforward control including a prediction compensation term is combined to shorten the time to reach the target temperature while enabling stable maintenance.

[0121] The temperature environment control step (S130) can be extended to a zone control method to ensure uniformity of internal heat distribution. Since temperature deviations may occur depending on the location of the mounting grooves arranged in a matrix form, the internal space is divided into multiple control zones, and the amount of heat generated or the flow rate of hot air for each zone is controlled independently. At this time, a structure that performs multivariable control based on sensor data for each zone can be applied, thereby suppressing the phenomenon of overheating or incomplete melting occurring only at specific locations and improving quality uniformity during parallel molding.

[0122] The temperature environment control step (S130) can improve process stability by introducing machine learning-based temperature prediction and correction logic. For example, by applying an LSTM-based model that predicts the temperature distribution at the next point in time using time-series data from internal temperature sensors as input, sudden fluctuations that may occur during the target temperature maintenance period can be preemptively corrected. In addition, automatic correction coefficients for heating output control can be generated through a model that learns overshoot patterns or thermal stratification patterns that occurred under specific conditions in conjunction with past process history.

[0123] The temperature environment control step (S130) further stabilizes the molding quality through linkage with the lifting drive control step (S140). If the splint material does not reach the target softening state, the lifting operation is delayed; conversely, if an excessive softening state is detected, the process can be adjusted by shortening the lifting holding time or lowering the temperature output. This linked control can be implemented with state-based control logic and contributes to increasing the molding success rate and reducing rework and waste rates. In addition, in abnormal situations such as overtemperature, sensor malfunction, or heat source malfunction, the heating output is immediately limited and the process is switched to a safe state, thereby ensuring the safety of the device and the working environment.

[0124] Detailed explanation of the elevator drive control step (S140)

[0125] The lifting drive control step (S140) is a step of driving the forming guide body (123) in the up and down direction by precisely controlling the air cylinder unit (121) and the lifting rod (122) of the lifting drive unit (120) to form the softened disc-shaped splint material into a target shape. The lifting drive control step (S140) is not a simple up-and-down movement, but rather induces the splint material to naturally bend due to its own weight and curved surface guidance by finely adjusting the rising speed, target position, holding time, and lowering speed according to the softening state of the material and the target curvature condition. Through this, positional errors and shape deviations that occurred in the conventional technology when an operator manually pressed to match the shape are systematically resolved.

[0126] The lifting drive control step (S140) may include control logic that takes into account the characteristics of pneumatic drive. Since the pneumatic system may experience minute shaking or positional errors due to the elasticity of compressed air, the lifting drive control step (S140) controls the lifting section by dividing it into multiple speed profiles. For example, in the initial lifting section, it approaches at a gentle speed to reduce contact impact, in the forming section, it rises at a constant speed to reach the target position, and near the target position, it applies deceleration control to prevent overshoot. This speed profile control can be implemented by combining the opening control and exhaust control of the pneumatic valve.

[0127] The lifting drive control step (S140) may apply sensor-based feedback control to ensure the reproducibility of the lifting position. A structure that continuously corrects the error relative to the target position by utilizing a linear encoder or proximity sensor signal that detects the position of the lifting rod (122) may be applied. In this case, in addition to simple PID control, applying model predictive control that reflects the delay and nonlinearity of the pneumatic system improves position accuracy. Such feedback control is advantageous for reproducing the same curvature even during repeated forming for the same target forming value.

[0128] The lifting drive control step (S140) can simultaneously realize different target shapes by independently controlling each lifting drive unit (120) in a parallel molding environment. Different molding guide spheres (123) may be installed according to the target molding value of each splint material, and each drive unit is controlled to have different lifting positions and holding times. Since pneumatic supply pressure fluctuations may occur when multiple drive units operate simultaneously, the lifting drive control step (S140) can adjust the number of simultaneous drives through priority-based scheduling logic or load distribution logic. This maintains the stability of the entire device and molding uniformity.

[0129] The lifting drive control step (S140) can be configured to enable continuous correction by considering the correlation with the forming result. Curvature errors or forming depth deviations identified during the result product review step are reflected in the correction of control parameters of the lifting drive control step (S140), thereby automatically adjusting the target position and holding time in the next forming process. Additionally, by applying reinforcement learning-based control, a lifting control policy that maximizes the success rate during the repetitive forming process can be learned. This adaptive control structure enables automatic optimization and precise reproduction that were impossible with conventional technology, thereby providing the effect of simultaneously improving the quality and productivity of customized splint manufacturing.

[0130] Detailed explanation of the result product review stage (S150)

[0131] The result product review stage (S150) is a stage for comprehensively verifying whether the splint, which has been molded through the lifting drive control stage (S140), meets the target molding value. In this stage, the overall shape, degree of curvature, surface condition, and structural stability of the molded splint are reviewed, and it is determined whether the molding process has produced the intended result. In conventional technology, the review was performed by a worker relying on visual inspection and tactile sense, but the result product review stage (S150) enables a more objective evaluation through standardized review items.

[0132] The result product review step (S150) can be performed with a focus on verifying shape consistency. For example, the curvature distribution of the formed splint is compared with the reference curvature set in the target forming value input step (S110) to determine whether it falls within the allowable error range. This comparison may include not only simple dimensional comparisons but also the continuity of bending or uniformity of deformation at multiple points, thereby enabling the detection of localized forming defects or asymmetry issues.

[0133] The result product review stage (S150) also serves to evaluate the repeatability of the molding quality. By comparing shape deviations between multiple splints produced under the same conditions, it is possible to verify whether process stability and reproducibility have been ensured. This review is particularly important in a parallel molding environment and serves as a criterion for determining process abnormalities by detecting minute deviations occurring only at specific locations at an early stage.

[0134] The result product review stage (S150) may incorporate subjective evaluations by users or medical professionals. Since factors such as fit, pressure distribution, and wearing comfort during actual wear are often difficult to quantify, these qualitative evaluation results can be recorded and included in the review results. This provides a foundation for systematically managing feedback that was previously utilized only empirically in conventional technology.

[0135] The result product review stage (S150) can ultimately classify and determine the molding results into normal ranges, ranges requiring correction, and ranges requiring re-molding. This determination result is not limited to a simple pass / fail status but is utilized as input data for subsequent process improvement. Through this, individual molding results do not end as isolated outcomes but are naturally connected to control improvements in the next stage.

[0136] Detailed explanation of the optimal control feedback step (S160)

[0137] The optimal control feedback step (S160) is a step that corrects the control conditions of the entire molding process and reflects them in the next manufacturing process based on the evaluation results derived from the result product review step (S150). This step is a key step that realizes that the manufacturing method of the present invention is not a simple repetitive process, but a structure that is gradually optimized through repetitive operation. In conventional technology, feedback on molding results was accumulated only through the operator's experience, but the optimal control feedback step (S160) feeds this back into the control system.

[0138] In the optimal control feedback step (S160), information on shape error, curvature deviation, and surface non-uniformity identified in the result product review step (S150) is used to correct control parameters. For example, if the forming depth is repeatedly insufficient under specific conditions, the target position or holding time of the lifting drive control step (S140) can be automatically corrected. This correction can be performed through predefined rule-based logic.

[0139] The optimal control feedback step (S160) can be extended to a machine learning-based learning structure. By applying a regression model or a neural network model that has learned the relationship between forming conditions and result quality, the most suitable control parameters for the next forming process can be predicted based on feedback information. Such a learning structure operates in a way that improves forming accuracy as repeated production is performed.

[0140] The optimal control feedback step (S160) may have an integrated feedback structure that simultaneously corrects the temperature environment control step (S130) and the lifting drive control step (S140). It analyzes whether the shape error is caused by temperature non-uniformity or by lifting position error, and selectively corrects the control items corresponding to each. This multivariable feedback structure provides higher control precision than the conventional method that assumed only a single cause.

[0141] The optimal control feedback step (S160) functions as a data accumulation step for long-term process stabilization. As molding history, control conditions, and review results accumulate, the device gradually secures an optimal control pattern for a specific material, specific shape, and specific environment. Through this, a high level of completeness can be secured from the initial setup stage, even when remanufacturing for the same user or repeating production under similar conditions, and the personalized splint manufacturing method of the present invention continuously maintains superior precision and reproducibility compared to conventional technology.

[0142] As explained above, the personalized splint manufacturing device according to the present invention has the effect of fundamentally improving the structure dependent on skilled workers, which was pointed out as a problem in the prior art. Unlike existing methods where the molding shape and process conditions were determined by the worker's experience or senses, the workpiece mounting unit and the lifting drive unit are arranged in a standardized structure and controlled by the molding control unit, thereby enabling stable securing of molding quality above a certain level regardless of the worker's skill level. Accordingly, the problem of quality imbalance caused by variations in manpower is substantially resolved.

[0143] This invention effectively resolves the issues of shape errors and wearing discomfort that frequently occurred during conventional splint molding processes. By adopting a structure that guides the disc-shaped splint material to naturally bend along a molding guide sphere due to its own weight, deformation caused by forced compression or localized pressure can be prevented. As a result, the user's body curvature can be reflected more precisely, and the likelihood of concentrated pressure or pain during wear is significantly reduced.

[0144] Furthermore, the present invention has the effect of improving the temperature environment control problem that was a weakness in conventional technology. By forming and controlling an independent temperature environment within the mounting portion of the workpiece to be molded, the thermoplastic material can stably maintain a state optimized for molding. Accordingly, the occurrence of problems such as molding defects, sagging, and thickness deviation is suppressed, and the shape stability and durability of the splint are improved.

[0145] This invention significantly improves productivity by refining the inefficient manufacturing process that was previously performed repeatedly for each individual user. By simultaneously mounting multiple disc-shaped splint materials at regular intervals and independently controlling the corresponding lifting drive units for each, multiple customized splints can be molded in parallel. This reduces manufacturing time and enables rapid mass production, which was difficult with conventional technology.

[0146] Furthermore, the present invention complements the limitations of conventional technology in terms of the working environment. By including a structure that purifies harmful gases generated during the heating process of splint materials and exhausts them to the outside, it is possible to protect the health of workers and maintain the comfort of the workspace. This has the effect of substantially improving safety issues that were overlooked in existing splint manufacturing environments.

[0147] This invention improves process reproducibility and management efficiency, which were lacking in conventional technology, by integrating the entire molding process based on a control system. By deriving the optimal molding environment according to target molding values ​​and controlling temperature and lifting drives in conjunction, uniform results can be secured even during repetitive production under identical conditions. This enhances the reliability of quality control and facilitates the accumulation and improvement of process data.

[0148] Consequently, the present invention effectively resolves the high manufacturing costs and supply limitations identified as issues in conventional technology. Through the automation and parallelization of the manufacturing process, labor costs and working hours can be reduced, and costs related to rework and waste can be minimized by ensuring stable quality. Accordingly, customized splints that immediately reflect the user's physical condition and requirements can be provided at a reasonable cost, offering substantial technical benefits that overcome the structural limitations of conventional technology.

[0149] The above detailed description of the present invention describes only specific embodiments thereof. However, it should be understood that the present invention is not limited to the specific forms mentioned in the detailed description, but rather should be understood to include all variations, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims.

[0150] In other words, the present invention is not limited to the specific embodiments and descriptions described above, and any person skilled in the art to which the present invention pertains can make various modifications without departing from the essence of the invention as claimed in the claims, and such modifications fall within the scope of protection of the present invention.
