Description

[0001] This application is a divisional application of Chinese invention patent application filed on April 21, 2021, with national application number 2021800283865 (PCT / US2021 / 028372) and invention title "Modular and Dynamic Force Device".

[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 014,191, filed April 23, 2020, entitled “DYNAMIC RESISTANCE EXERCISE MODULE”, which is incorporated herein by reference. Technical Field

[0003] The implementation described herein generally relates to modular dynamic force modules for altering unique dynamic forces during different forms of physical activity. Background Technology

[0004] Compared to static weights or specialized electromechanical training systems, the dynamic and variable forces used during physical activity can maximize efficiency and reduce injury or strain.

[0005] Some exercise equipment utilizes resistance mechanisms, such as U.S. Patent No. 6,440,044. However, U.S. Patent No. 6,440,044 is limited in the amount of resistance it can provide to the user. Furthermore, the resistance mechanism is based on weights, rather than the force generated by the user. This makes it easier for users to over-fatigue their muscles and increases the risk of injury.

[0006] U.S. Patent Publication No. 20030027696 teaches a cable machine having a counterweight stack attached to a cable. A pulley system is used, which limits the usable range of motion and may cause the user to over-isolate individual muscles, potentially leading to injury.

[0007] Resistance bands, such as those described in U.S. Design Patent No. 750,716, can be attached to different devices to provide various forces across different ranges of motion; however, the resistance is limited depending on the band's mass. Furthermore, the resistance generated by using a band throughout physical activity is static.

[0008] U.S. Patent Publication No. 20080119763 teaches a system for acquiring, processing, and reporting personal exercise data about selected muscle groups by measuring vector forces from at least one muscle or muscle group acting on a physical exercise device. The system provides information to the user, enabling the user to manually adjust the exercise device.

[0009] U.S. Patent Publication No. 20200151595 discloses the processing of sensor data to improve user training. This invention provides users with feedback and suggestions for adjusting form and manual resistance in subsequent training program modifications.

[0010] U.S. Patent No. 10,661,112 discloses digital force training using received information relating to the position of an actuator connected to a motor via a cable.

[0011] Existing technologies have failed to provide a modular dynamic motion resistance module that analyzes real-time data to provide automatic, real-time adjustment of force. This invention improves the efficiency and accuracy of physical activities such as exercise, and reduces user injury and strain. Summary of the Invention

[0012] This invention provides a system and method for improving the efficiency of physical activity.

[0013] The Dynamic Motion Resistance Module (“DMRM”) and the method of generating variable force represent an improvement over existing technologies. This is because the DMRM uses variable torque force (such as a DC motor, eddy current, friction clutch, or torsion sensor) that is converted into a linear force and controlled by a microprocessor. The DMRM receives adjustments based on various sensors and calculated optimized forces. This allows the user to perform physical activities, such as exercises, based on their unique abilities, which generate variable forces based on the magnitude of the force the user is able to apply. If the user's ability to apply force fluctuates during activity, the force can vary in a single repetition or over a set of exercises. The DMRM is particularly helpful for users recovering from injuries and those aware of the importance of avoiding overexerting their muscles.

[0014] The exemplary embodiments disclosed herein describe a module that provides dynamic force control, which performs electromechanical control within a closed-loop device (mechanical, electrical, and software) that can modify the relative force experienced by the user and adapted to the individual based on various input variables during physical activity, such as training or treatment sessions. Input variables include repetition rate, recovery period, current physical activity configuration, daily goals, historical guidance, and AI adjustments. Input variables can be received from a mobile application associated with the user's device or from the force module. The DMRM differs from other physical activity equipment, such as static Olympic weight plates, because it is a modular system that uses variable torque force to generate dynamic force for the user in real time. Therefore, the DMRM can be used as an alternative module to static weight plates.

[0015] DMRM optimizes the efficiency of each body activity and force based on inputs from various one or more sensors and calculated adjustments, thereby improving the user's physical activity by adapting and modulating forces. Sensors may include Hall effect sensors for positioning, strain gauges for forces (e.g., force-sensitive resistors, piezoelectric sensors, optical sensors, or torsional sensors), and contact closure or proximity detection for safety interlocks or motor controllers.

[0016] DMRM can be attached to many Olympic barbell or standard barbell and dumbbell components or other exercise equipment to add dynamic force to other static masses.

[0017] DMRMs can be installed in unique ways. DMRMs can be configured and used for static force routines with programmable force and hold time to accommodate daily physical activities or the same closed-loop force modulator can be added to other physical exertion applications and treatments.

[0018] A modular and dynamic force device for real-time adjustment of standard and dynamic torque-to-linear forces during physical activity, the device comprising a force module, a user device, and a device tracking and processing unit. The force module includes: an attachment point of an open hub for attaching the device to an external source; one or more sensors for measuring data regarding the efficiency of physical activity; an internal processor, a radio and force sensor module; a variable-length cable; force generating components; and a motor controller. The internal processor, radio, and force sensor module includes: a device tracking measurement unit (“ATMU”) adapted to measure the data; a first electronic communication channel for transmitting the measured data to the device tracking and processing unit (“ATPU”); and a second electronic communication channel for transmitting one or more device status data for adjusting the dynamic force. The user device receives one or more device status data via the second electronic communication channel to notify and / or adjust the force in real time. The user interface includes a display providing feedback and the device tracking and processing unit (“ATPU”). The ATPU includes a first electronic communication channel for receiving measurement data from the ATMU, a microprocessor, a memory storage area, a database stored in the memory storage area, and a tracking processing module located in the memory storage area. The database stores a first set of evaluation rules and a second set of evaluation rules, the first set corresponding to one or more tracking parameters, and the second set corresponding to one or more device conditions. The tracking processing includes program instructions that, when executed by the microprocessor, cause the microprocessor to: determine one or more tracking parameters using the measurement data and the first set of evaluation rules, and determine one or more device condition data using the one or more tracking parameters and the second set of evaluation rules.

[0019] The present invention also relates to a method for real-time adjustment of standard and dynamic torque-to-linear force during physical activity, the method comprising: attaching a modular dynamic force module to a substantially fixed base, the modular dynamic force module being operatively connected to a device used by a user during physical activity, wherein the modular dynamic force module includes an attachment portion of an open hub, one or more sensors, an internal processor, a tracking measurement unit, a variable-length cable, a force generating component, and a motor controller; collecting real-time activity data generated by the tracking measurement unit, the activity data representing the torque-to-linear force generated by the user during physical activity; transmitting the activity data to a force processing unit for analysis according to a predetermined set of evaluation rules; applying a first set of evaluation rules to determine at least one tracking parameter using the activity data; applying a second set of evaluation rules to determine at least one device condition parameter using the at least one tracking parameter; transmitting the at least one device condition parameter to a user device; causing the user device to provide real-time notification of the at least one device condition parameter; and causing the modular dynamic force module to adjust the torque-to-linear force experienced by the user in real time.

[0020] In some implementations, the method further includes storing a first set of evaluation rules and a second set of evaluation rules in a database.

[0021] In some implementations, the method further includes supplying power to the regulated torque-to-linear force via an internal and self-contained power source.

[0022] In some implementations, the method further includes providing sensor feedback for sending drive and / or resistance commands to refine body activity.

[0023] In some implementations, the method further includes locking the modular dynamic force module when stray forces are detected.

[0024] In some implementations, the user is at least one person engaged in physical strength training.

[0025] In some implementations, a regulated torque to linear force is applied for a single repetition.

[0026] In some implementations, a tuned torque-to-linear force is applied to a set of exercises as the force applied by the user fluctuates during physical activity.

[0027] In some implementations, the user is an animal. Attached Figure Description

[0040] Figure 12 This demonstrates an alternative use of the DMRM when a user pulls the variable force cable. Detailed Implementation

[0041] The DMRM's unique modularity allows it to be attached to a variety of traditionally used force apparatuses (such as barbells, racks, benches) and used in other physical activities. The DMRM includes a fully enclosed / feedback loop motor controller that adjusts and refines in real time based on the user's dynamic or anatomical response to the applied force. This allows the user to simultaneously engage multiple muscle groups across a virtually unlimited range of physical forces and motions. The variable force is based on the applied user force and limits the possibility of injury. Furthermore, the invention has a smaller mass than a conventional static weight plate, so accidentally dropping the device on a toe or finger may cause less injury to the user. Modularity, combined with a novel device for replicating variable force, and a lighter weight, distinguish the DMRM from any other force apparatus.

[0042] DMRM can be used for various types of physical activities. This includes exercise, boundary constraints, safety modules, and two-person interactive activities.

[0043] Figure 1 An example of a modular, stand-alone dynamic motion resistance module 1 is shown. While some exemplary embodiments described herein are tailored for stand-alone modules, the currently disclosed devices and methods are not limited to this configuration and can be used in other apparatus environments employing similar applications and methods. One or more modules may be mounted or anchored to the instrument used.

[0044] like Figure 1 As shown, the device includes an open hub 13 sized to fit various types of equipment, such as Olympic or standard barbells and dumbbell components. An outer housing 10 houses a dynamic force component, including a motor such as a DC motor, power supply, intelligent controller / wireless communication, sensors, an embedded processor, and cables or reels 4. The module may also include a display. The cables or reels 4 of the DMRM 1 provide connection points 5 for attaching hand grips, levers, or anchor points for user access to the attached module. Sensors may include: torsional sensors, such as Hall effect sensors, strain gauges, and safety interlocks; and external physiological sensors, such as heart rate, force, timing, training type, calorie consumption, training repetition rate, and training history. The sensors are located within the force module, but their specific locations may vary. Sensors may be positioned together with the internal processor and radio module, or they may be positioned separately within the force module. Sensor feedback may be auditory, tactile, and / or sensory. The DMRM 1 is mounted on an internal rotating section 13 that provides varying force to the belt or cable 4 in the linear direction 2, allowing the user to experience varying force based on sensor-controlled and calculated input to optimize physical activity. The DMRM 1 also houses signage and branding space 16.

[0045] Figure 2 An exemplary illustration of the internal force functions of the DMRM 1 is shown, illustrating the main components used in transmitting dynamic forces, including a linear force vector 2 generated by the internal rotational force 3 and a typical communication device 9 that sends commands to the module to change forces. Torque to linear force is generated by a motor, gear, pulley, or vortex-driven component 6 powered by a power source 7, such as a battery or line power. Force and communication are handled by an internal processor, radio, and force sensor module 8, which serves as both an Equipment Tracking Measurement Unit (“ATMU”) that alternately receives control commands from a commercially available external device 9 and a self-contained integrated DMRM (offline / manual mode), the external device 9 serving as an Equipment Tracking Processing Unit (“ATPU”). The ATMU measures data from the device / module and transmits the measured data to the ATPU using an electronic communication channel. The ATMU uses a second electronic communication channel to transmit one or more of the device status data to a user interface for adjusting dynamic forces. A local user interface on the device or related application is used to adjust all force and physical activity configurations. The ATPU includes a microprocessor and a memory storage area. The memory storage area includes a database and a tracking processing module. The tracking processing module includes program instructions that, when executed by the microprocessor, use measured data and a set of evaluation rules to determine one or more tracking parameters, and use one or more of the tracking parameters and another set of evaluation rules to determine the device and / or module condition measured by the ATPU. The database stores the sets of evaluation rules. At least one set of rules corresponds to one or more of the individual tracking parameters, such as repetitions per minute, total repetitions, calories burned, and goals achieved; the other set of evaluation rules corresponds to one or more device and / or module conditions.

[0046] The embedded processor in Module 1 monitors the electric motor control loop, sensor management, and wireless communications such as Bluetooth Low Energy (BLE), Wi-Fi, or cellular. The embedded processor provides local control and computation, as well as variables such as mains power, timers, motor control configuration, start / stop, force, and safety interlock status. The embedded processor can also provide computed or raw data to the ATPU, allowing for higher-level computations to be performed at any boundary of the architecture. The ATPU is a logic element that can physically reside within the DMRM or in the user interface. The ATPU transmits device status, such as battery charge status, safety status, and system health. Optimized linear force is directed to cable or strip 4. Cable or strip 4 includes attachment points 5, which can be, for example, clamps, eye hooks, or other common or custom attachment points to allow for various accessories and attachment options to cable or strip 4. When the module is in an "offline" state, it can be in a low-power sleep mode or powered off.

[0047] Figure 3a and Figure 3b This illustrates how the DMRM 1 applies its force and internal force functions in practice. The generated force vector 2 can be accommodated via an internal industry-standard / universal barbell or dumbbell bar 30 or other universal hub adapters for connecting / installing the module. The strap or cable 4 and attachment point 5, in a linear direction, allow the user to experience varying forces based on sensor- and calculated inputs to optimize physical activity. The DMRM 1 includes various safety mechanisms, such as cable safety stops (cut-off switches), anchor points (… Figure 3a Foot anchor 18 or Figure 3b The ground anchor 17 and / or hardware / software control and feedback loops (sensors, electronics, software) for real-time closed-loop control and dynamic force application. The foot anchor 18 counteracts the applied force to achieve a dynamic free weight experience.

[0048] Figure 4a , Figure 4b and Figure 4c The DMRM 1, used with the pressing bench 40, is shown. The DMRM 1 is mounted on the bar 30. The user is able to perform various exercises with different ranges of force vector 2. Figure 5 The use of DMRM 1 on rowing machine 50 is illustrated. User interface 9 can be part of the rowing machine or a separate user interface, such as a smartphone. Two DMRM 1s are attached to rowing machine 50; however, the number of modules attached to the machine can be one or more. The user pulls cable 4 while rowing on rowing machine 50 and receives real-time feedback and the tactile sensation of actually rowing in the water.

[0049] Figure 6, Figure 7 , Figure 8 and Figure 9 Exemplary examples of other uses of the DMRM 1 are shown. In addition to mounting the DMRM to conventional exercise equipment, a static weight plate 14 can be added, such as... Figure 6 As can be seen, DMRM 1 can be installed in other ways, for example, DMRM 1 can be installed to one or more anchor points 70 on a load-bearing structure, and then DMRM 1 can be attached to the swimmer's harness 15 to adjust or measure dynamic body movement forces during swimming. Figure 7 ).like Figure 8 As can be seen, DMRM 1 can also be used for two-person interactive exercise or therapeutic activities. For example, one user holds a barbell 80 with two modules, while another user attaches a barbell (or other form of equipment) 85 to a strap or cable 4 via attachment point 5. For example, as Figure 9 As shown, another example attaches the DMRM 1 to an animal or pet via a harness or leash 12. The DMRM 1 provides the animal with freedom of movement unless the animal reaches a user-defined boundary 92. When the defined boundary 92 is reached, a dynamically applied force begins to exert resistance, resulting in complete stopping within a controlled length and restraint (e.g., hold or lock mode).

[0050] Figure 10 , Figure 11 and Figure 12 Other alternative uses for DMRM 1 are provided. Figure 10 This illustrates attaching the DMRM 1 to the treadmill 100 at attachment point 102, and attaching the cable or strap 4 to the user's waist via a safety belt or other connection point 104, thereby keeping the runner fully centered on the treadmill 100. For example, in... Figure 11 In addition, DMRM 1 can also be used as a safety braking module, which is attached to the user at attachment point 110, such as a seat belt, thereby providing the user (human or animal) with freedom of movement. If stray force is detected, or when stray force is detected, such as in the event of a fall or trip, the device will hold or lock, thereby securing the user. Figure 12 The diagram illustrates its use by a sprinter or figure skater, where the DMRM 1 is attached to the user during training via a harness or other connection point 19. The device senses and controls the force applied to the user. Furthermore, the module can be configured and used for static force routines with programmable force and hold time to suit daily physical activities, or the same closed-loop force modulation element can be added to other physical exertion applications and treatments.

[0051] In the foregoing specification, the present invention has been described with reference to specific embodiments thereof. However, it will be apparent that various modifications and changes can be made to the invention without departing from its broader spirit and scope. Therefore, this specification and the accompanying drawings should be viewed in an illustrative rather than restrictive sense.
