Description

Technical Field

[0001] This application relates to the field of "artificial intelligence + sports and health" technology, and in particular to a method, device, system and equipment for motion adjustment based on bistable state. Background Technology

[0002] With the rapid development of competitive sports and mass fitness activities, the scientific and refined nature of sports training has become central to improving athletic performance and promoting health. Against this backdrop, achieving precise quantitative identification and real-time feedback for collision and contact sports is a key technology for optimizing techniques, preventing injuries, and pushing limits.

[0003] However, traditional motion analysis methods rely heavily on coaches' visual observation and subjective experience. Since motion collisions are often instantaneous, high-speed, and high-impact, traditional motion analysis methods cannot accurately capture millisecond-level contact moments, minute limb deformations, or precise force points when detecting and adjusting motion collisions. This results in a large amount of key motion information being missed.

[0004] Therefore, motion identification and adjustment based on this traditional method is prone to missing a large amount of key motion information, and its accuracy and reliability are seriously insufficient. Not only is it difficult to support the optimization of athletic performance, but it may also increase the risk of sports injury due to inaccurate adjustment suggestions, resulting in poor sports science. Summary of the Invention

Find the target impact level that matches both the target impact intensity and the corresponding impact duration in the preset impact level table; The impact levels of multiple targets are plotted according to the positions of multiple bistable units to obtain the current impact distribution map for the collision site. The position of the target impact level in the current impact distribution map corresponds one-to-one with the position of the bistable unit.

[0011] Furthermore, the disc-shaped disc integrates a reset mechanism; the method also includes: After the impact force is applied to the collision site, a target disc-shaped disc that undergoes a steady-state change is obtained; After a preset time interval, the target disc is reset in a steady state using the reset mechanism integrated on the target disc.

[0012] Secondly, this application also provides a bistable motion sensing device, which applies the above-mentioned bistable motion adjustment method. The device includes multiple bistable flexible patches, on which multiple bistable units are uniformly arranged. Each bistable unit includes a disc-shaped disc and a strain sensor, with the strain sensor etched on the disc-shaped disc. A bistable flexible adhesive is attached to the collision site of a moving object. Multiple disc-shaped discs and multiple strain sensors are used to process the impact force acting on the collision site to obtain impact parameters.

[0013] Furthermore, a reset mechanism is integrated on the disc-shaped disc, which is used to perform steady-state reset of the target disc-shaped disc that has undergone steady-state changes.

[0014] Thirdly, this application also provides a bistable motion adjustment system, comprising: The impact force processing module is used to process the impact force acting on the collision part of a moving object using multiple bistable units to obtain impact parameters. The multiple bistable units are attached to the collision part, and the bistable units include a disc-shaped disc and a strain sensor. The strategy determination module is used to determine the collision response strategy for the collision site based on the impact parameters.

[0019] The following embodiments are further explanations and supplements to this application and do not constitute any limitation on this application.

[0020] The following describes a bistable motion adjustment method, apparatus, system, and device according to embodiments of this application, in conjunction with the accompanying drawings.

[0021] The bistable motion adjustment method provided in this application can be executed by a server. It should be noted that the server can be a standalone server or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (CDNs), and big data and artificial intelligence platforms. No limitation is imposed here.

[0022] Please see Figure 1 , Figure 1 An exemplary embodiment of this application illustrates a bistable motion adjustment method, such as... Figure 1 As shown, this application provides a motion adjustment method based on bistable states, including: S11, using multiple bistable units to process the impact force acting on the collision part of the moving object to obtain impact parameters, the multiple bistable units are attached to the collision part, the bistable units include a disc-shaped disc and a strain sensor; S12, Based on the impact parameters, determine the collision response strategy for the collision site; S13, Based on the collision response strategy, the motion of the moving object is adjusted to improve the scientific nature of the motion of the collision site.

[0023] The bistable motion adjustment method provided in this application firstly utilizes multiple bistable units attached to the collision site of a moving object to process the impact force acting on the collision site, obtaining impact parameters. By distributing detection across different parts of the same collision site using multiple bistable units, key motion information arising from subtle changes in the collision site can be preserved, ensuring the accuracy of the obtained impact parameters. Secondly, based on the accurate impact parameters, a collision response strategy is determined for the collision site, and the motion of the moving object is adjusted based on this strategy. This improves the reliability of motion adjustment, reduces the risk of motion injury caused by inaccurate motion strategies, and thus enhances the scientific accuracy of the collision site's motion. Simultaneously, the bistable units include disc-shaped discs that absorb energy from the impact force when it acts on the collision site, buffering the impact and reducing damage to the collision site, further improving the scientific accuracy of the motion.

[0024] Optionally, multiple bistable units are used to process the impact force acting on the collision site of the moving object to obtain impact parameters, including: Get the collision motion type of the moving object; Based on the type of collision motion, the collision points of the moving object are determined. Multiple bistable units are selected for bonding based on the collision location; The impact force acting on the collision site is processed using multiple bistable units to obtain the impact parameters.

[0025] In the embodiment provided in this application, multiple bistable units are selected and bonded together based on the collision site so that the multiple bistable units can uniformly cover the collision site. By using the disc-shaped discs and strain sensors included in the multiple bistable units to separately protect and detect different parts of the same collision site, it is possible not only to reduce the damage to the collision site caused by the impact force, but also to retain the key motion information generated by the subtle changes in the collision site. This ensures that the obtained impact parameters meet the accuracy requirements, thereby reducing the risk of motion injury caused by inaccurate motion strategies and achieving a dual guarantee of the scientific nature of motion.

[0026] The types of sports collisions include American football, rugby, ice hockey, combat sports, soccer, basketball, and hockey. The main collision sites for American football are the head, shoulder, knee, and torso; for rugby, the main collision sites are the head, shoulder, and knee; for ice hockey, the main collision sites are the shoulder, elbow, and torso; for combat sports, the main collision sites are the head and torso; for regular soccer, the main collision sites are the head (for headers), shoulder, waist, shin, and ankle; for basketball, the main collision sites are the elbow, knee, and ankle; and for hockey, the main collision sites are the lower leg, foot, and torso.

[0027] Optionally, the impact force acting on the collision site is processed using multiple bistable elements to obtain impact parameters, including: Multiple disc-shaped discs are used to absorb the energy of the impact force acting on the collision site; The impact force was detected by using multiple strain sensors, and the resistance change and resistance change duration of each strain sensor were obtained. Impact parameters are formed based on multiple resistance changes and multiple resistance change durations.

[0028] In the embodiment provided in this application, multiple disc-shaped plates are used to absorb the energy of the impact force acting on the collision site, thereby buffering the impact force and reducing the damage to the collision site, thus improving the scientific nature of the motion. Simultaneously, by detecting the impact force using multiple strain sensors, key motion information generated by subtle changes at the collision site can be preserved. This ensures that the impact parameters formed by the resistance change and duration of each strain sensor meet accuracy requirements. This facilitates the reliability of subsequent motion adjustments based on collision response strategies determined using accurate impact parameters, reduces the risk of motion injury caused by inaccurate motion strategies, and further improves the scientific nature of the motion.

[0029] In this embodiment, the disc-shaped disc absorbs energy from the impact force acting on the collision site through a negative stiffness effect and peak force clipping. The negative stiffness effect occurs because the disc-shaped disc has a bistable structure. During the transition from the first stable state to the second stable state, a negative stiffness region appears in the force-displacement curve. This means that as deformation increases, the resistance decreases, thus absorbing and dissipating a large amount of energy (i.e., the area under the force-displacement curve in the figure). Peak force clipping transforms the high-impact, sharp force pulse (high peak value, short duration) into a longer-duration, plateau-like force response, significantly reducing the peak acceleration transmitted to the protected object, thereby achieving buffering.

[0030] In an exemplary embodiment provided in this application, different steady-state trigger thresholds are set for multiple disc-shaped discs. In this way, when an impact force is applied to multiple disc-shaped discs, the disc-shaped discs with lower thresholds are triggered first, undergo steady-state changes, and dissipate some energy. If the impact continues, the disc-shaped discs with higher thresholds are triggered sequentially, realizing graded energy dissipation, thereby solving the problem of peak impact force overload.

[0031] Optionally, the impact parameters include the resistance change and the duration of the resistance change detected by each strain sensor; based on the impact parameters, a collision response strategy is determined for the impact site, including: Construct a standard impact distribution map for the collision site; Based on multiple resistance changes and multiple resistance change durations, a current impact distribution map is generated for the collision site. By comparing the current impact distribution map with the standard impact distribution map, collision response strategies for the impact points are determined.

[0032] In the embodiment provided in this application, a current impact distribution map for the collision site is formed based on multiple resistance changes and multiple resistance change durations. A collision response strategy for the collision site is then determined by comparing the current impact distribution map with a standard impact distribution map for that site. Since the size information of the collision site is different for each moving object, using a specific standard impact distribution map improves the reliability of the collision response strategy determined by comparison with the standard impact distribution map. This facilitates subsequent motion adjustments based on the collision response strategy, reduces the risk of motion injury caused by inaccurate motion strategies, and ultimately improves the scientific accuracy of the motion at the collision site.

[0033] In an exemplary embodiment provided in this application, the collision response strategy may include an adjustment strategy for the main force-bearing area and the main force-bearing direction of the collision site. At the same time, it may also provide a force-resisting strategy (active collision strategy) or a force-retreating strategy (retreating in the direction of impact to achieve a certain degree of force avoidance, gradually offsetting the impact force by lengthening the contact time of the collision, thereby flexibly responding to the impact force and improving the scientific nature of sports) based on the endurance level of the athlete's collision site.

[0034] Optionally, based on multiple resistance changes and multiple resistance change durations, a current impact distribution map for the collision site is formed, including: Find the target impact strength that matches the change in resistance in the preset impact strength table; The duration of resistance change is defined as the impact duration. Find the target impact level that matches both the target impact intensity and the corresponding impact duration in the preset impact level table; The impact levels of multiple targets are plotted according to the positions of multiple bistable units to obtain the current impact distribution map for the collision site. The position of the target impact level in the current impact distribution map corresponds one-to-one with the position of the bistable unit.

[0035] In the embodiment provided in this application, the target impact intensity matching the resistance change is determined by looking up a table, and the target impact level matching both the target impact intensity and the corresponding resistance change duration is determined. Multiple target impact levels are then plotted according to the positions of multiple bistable units to obtain a current impact distribution map for the collision site. This allows for parameterized conversion of the impact force on the collision site, facilitating the subsequent scientific comparison between the current impact distribution map and a standard impact distribution map to determine the reliability of the collision response strategy. This also facilitates subsequent motion adjustments based on the collision response strategy, reducing the risk of motion damage caused by inaccurate motion strategies, and ultimately improving the scientific nature of the collision site's motion.

[0036] Optionally, the disc-shaped disk integrates a reset mechanism; the method further includes: After the impact force is applied to the collision site, a target disc-shaped disc that undergoes a steady-state change is obtained; After a preset time interval, the target disc is reset in a steady state using the reset mechanism integrated on the target disc.

[0037] In the embodiment provided in this application, after the impact force acts on the collision site, the disc-shaped disc exceeding its steady-state trigger threshold will undergo a steady-state change to obtain the target disc-shaped disc. After a preset time interval, the target disc-shaped disc is steadily reset using the reset mechanism integrated on it, so that the target disc-shaped disc can return to its previous steady state. This allows the disc-shaped disc to repeatedly absorb the energy of the impact force, thereby not only improving its reusability but also extending the protection time of the impact site, further improving the scientific nature of the motion.

[0038] An embodiment of this application provides a bistable motion sensing device that applies the aforementioned bistable motion adjustment method. The device includes multiple bistable flexible patches, on which multiple bistable units are uniformly arranged. Each bistable unit includes a disc-shaped disc and a strain sensor, with the strain sensor etched on the disc-shaped disc. A bistable flexible adhesive is attached to the collision site of a moving object. Multiple disc-shaped discs and multiple strain sensors are used to process the impact force acting on the collision site to obtain impact parameters.

[0039] The bistable motion sensing device provided in this application utilizes multiple bistable units mounted on a bistable flexible adhesive attached to the collision site of a moving object to process the impact force acting on the collision site and obtain impact parameters. By distributing detection across different parts of the same collision site using multiple bistable units, key motion information arising from subtle changes in the collision site can be preserved. This ensures the accuracy of the obtained impact parameters, thereby improving the reliability of subsequent motion adjustments based on collision response strategies determined using accurate impact parameters. This reduces the risk of motion injury caused by inaccurate motion strategies, thus enhancing the scientific rigor of motion analysis. Furthermore, the bistable units include disc-shaped discs that absorb energy from the impact force when it acts on the collision site, buffering the impact and reducing damage to the collision site, further improving the scientific rigor of motion analysis.

[0040] In this embodiment, multiple disc-shaped discs are used to absorb the energy of the impact force acting on the collision site. The disc-shaped discs are made of spring steel, polymer, or composite materials. The disc-shaped discs exist in two stable states. For example, state one (stable state A): the disc-shaped disc is convex (arched upwards); state two (stable state B): the disc-shaped disc is concave (depressed downwards).

[0041] By setting different steady-state trigger thresholds for multiple disc-shaped discs, when an impact force is applied to multiple disc-shaped discs, the disc-shaped discs with lower thresholds are triggered first, undergoing steady-state changes and dissipating some energy. If the impact continues, the disc-shaped discs with higher thresholds are triggered sequentially, achieving graded energy dissipation, thereby solving the problem of peak impact force overload.

[0042] Multiple strain sensors are used to detect impact parameters of the impact force acting on the collision site. These parameters include the change in resistance and the duration of the resistance change. Microchannels are fabricated in the high-strain region of each disc-shaped wafer using laser engraving or soft lithography, and liquid metal is injected using vacuum infusion technology to form the strain sensors. When subjected to impact, the disc-shaped wafer deforms, causing the microchannels of the strain sensors to be stretched dramatically. This results in a large, step-like, irreversible (requiring reset) increase in the resistance of the strain sensors (resistance change ΔR). The magnitude of ΔR is positively correlated with the impact intensity.

[0043] Optionally, the disc-shaped disc also integrates a reset mechanism, which is used to perform a steady-state reset of the target disc-shaped disc that has undergone a steady-state change.

[0044] In the embodiment provided in this application, a reset mechanism is used to perform steady-state reset on the target disc-shaped disc that has undergone a steady-state change. This allows the target disc-shaped disc to return to its previous steady state, enabling it to repeatedly absorb energy from impact forces. This not only improves its reusability but also extends the protection time of the impact site, further enhancing the scientific nature of motion. The reset mechanism can be driven by a shape memory alloy (SMA) wire.

[0045] In an exemplary embodiment provided in this application, an event triggering sensor is provided between the bistable flexible patch and multiple bistable units. The event triggering sensor is used to record impact parameters when an impact force is applied to the collision part, and upload the impact parameters to the host computer so that the host computer can determine the collision response strategy for the collision part based on the impact parameters, and adjust the motion of the moving object based on the collision response strategy to improve the scientific nature of the motion of the collision part.

[0046] Specifically, the event-triggered sensor can be a polyvinylidene fluoride (PVDF) piezoelectric film.

Secondly, a strategy determination module 202 determines a collision response strategy for the collision site based on the accurate impact parameters, and the motion adjustment module 203 adjusts the motion of the moving object based on the collision response strategy. This improves the reliability of motion adjustment, reduces the risk of motion injury caused by inaccurate motion strategies, and thus enhances the scientific accuracy of the collision site's motion.
