Description

Technology Field

[0001] The present invention relates to a device for measuring the weight of quadrupedal animals, such as dogs, and more specifically, to a device for measuring the weight and weight distribution of quadrupedal animals that can accurately measure the weight and weight distribution of quadrupedal animals, and in particular, can determine the final weight by tracking and correcting weight fluctuations caused by movement even if there are fluctuations in the measured value caused by the animal's movement, and can calculate and display the weight distribution in the front / back and left / right directions, and can be utilized in fields such as veterinary medicine, animal rehabilitation treatment, pet health management, and the development of precision medical devices for animals. Background Technology

[0003] "Companion animal" is a term referring to an animal kept at home for emotional support. As the perception spreads that animals are not mere toys but companions living alongside humans, they are commonly referred to as companion animals; representative examples include dogs and cats.

[0004] As of the end of 2020, the number of "pet-owning households" in Korea stood at 6.04 million, accounting for 29.7% of all households, while the number of pet owners reached 14.48 million, putting the country on the verge of the "era of 15 million pet owners." These figures are estimated based on basic data from Statistics Korea, the Ministry of Agriculture, Food and Rural Affairs' animal registration information, and a survey of 1,000 men and women aged 20 or older nationwide. Due to changes in Korea's family structure, such as the increase in single-person households and the rise of nuclear families, it is estimated that one in four households raises a pet. Furthermore, industries and culture related to pets are rapidly expanding, growing inversely to the social and demographic changes of population decline.

[0005] As mentioned above, with the increase in pet culture, consumers raising pets recognize them as members of the family; along with the rise in the status of pets, diseases and care, which serve as the most representative indicators of their quality of life, have become major areas of interest.

[0006] As mentioned above, when checking the health of quadrupedal animals such as dogs and cats, checking their body weight is performed as a basic procedure.

[0007] Quadrupedal animals have difficulty maintaining a completely fixed posture when weighing, so they often make continuous, fine movements on the scale. As a result, the scale is affected by momentary fluctuations, which limits its ability to calculate accurate weight.

[0008] In particular, given the characteristics of quadrupedal animals where body weight is distributed across four support surfaces (support surfaces for the limbs), accurately determining the weight distribution in the front / rear and left / right directions is an important factor in analyzing the health status of individual animals and evaluating their rehabilitation.

[0009] Conventional scales primarily calculated total weight using a single point or a minimal number of sensors, and had the problem of failing to measure weight distribution by limb or provide correction functions for the animal's continuous postural changes.

[0010] As an example of prior related technology, Korean registered patent No. 10-2344722 describes technology regarding a smart weight device for measuring the obesity level of pets and a method for managing pets using the same. Prior art literature

[0045] Hereinafter, a weight measuring device for quadrupedal animals according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0046] FIG. 1 is a drawing showing a weight measuring device for a quadruped animal according to the present invention, FIG. 2 is a drawing viewed from the top surface of a weight measuring device for a quadruped animal according to the present invention, and FIG. 3 is a drawing showing a disassembled view of a weight measuring device for a quadruped animal according to the present invention.

[0047] The weight measuring device for a quadrupedal animal according to the present invention is a weight measuring device for a quadrupedal animal including a dog and a cat for measuring the weight (body weight) of a quadrupedal animal, and as shown in FIGS. 1 to 5, it mainly comprises a device body (100), a weight detection module (200), a weight analysis module (300), and a control module (400).

[0048] Specifically, the weight measuring device for a quadruped animal according to the present invention is a weight measuring device for a quadruped animal including a dog and a cat, and as shown in FIGS. 1 to 5, comprises: a device body (100) formed to have a size on which a quadruped animal can stand; a weight detection module (200) provided on the device body (100) and configured to independently measure a load in each area corresponding to each limb position when the quadruped animal is standing on four legs; a weight analysis module (300) configured to receive a load measurement signal measured in each area of ​​the weight detection module (200), calculate a final weight, and analyze a weight distribution; and a control module (400) configured to include a display unit (420) configured to turn the device on / off and to visually provide the results analyzed by the weight analysis module (300) to the user.

[0049] The above device body (100) includes components described in detail below and is a component formed with a size and shape that allows a quadrupedal animal to stand on it.

[0050] Specifically, the device body (100) has a control module (400) inside and includes a device body (110) formed in a rectangular shape and a pad member (120) that forms the upper surface of the device body (110) on which a four-legged animal stands.

[0051] A height adjustment mechanism capable of height adjustment may be provided at the corner portion of the lower surface of the device body (110).

[0052] The pad member (120) may be formed as a pad made of silicone or rubber material to prevent slipping. A weight detection module (200), which will be described in detail below, is provided at the bottom of the pad member (120).

[0053] Drawing symbol 130 is a handle that grips the device to provide mobility.

[0054] Furthermore, the weight detection module (200) is provided at the bottom of the pad member (120) of the device body (100) and is configured to measure a load independently in each area corresponding to each limb position when a quadrupedal animal is standing on four legs.

[0055] The above weight detection module (200) may be composed of a pressure sensor such as an FSR sensor or a piezoelectric sensor.

[0056] In the present invention, the weight detection module (200) may be composed of a plurality of FSR sensors that are independently arranged for each stepping area of ​​a quadrupedal animal. In other words, the weight detection module (200) of the present invention is composed of four-channel independent pressure sensors installed on a platform where the animal's four legs can be positioned.

[0057] Each section sensor module measures individual load data applied to the front left and right and rear left and right legs of the animal in real time and transmits it to the weight analysis module (300).

[0058] Specifically, in the present invention, the weight detection module (200) is configured to include a front left (FL_L) section sensor module (210), a front right (FL_R) section sensor module (220), a rear left (HL_L) section sensor module (230), and a rear right (HL_R) section sensor module (240), and each of the section sensor modules (210 to 240) independently detects a load (weight), and each detection signal is transmitted to a weight analysis module (300).

[0059] Next, the weight analysis module (300) is configured to receive load measurement signals measured in each area of ​​the weight detection module (200), calculate the final weight, and analyze the weight distribution, and is configured to track weight fluctuations based on real-time pressure data (load detection signals) transmitted from the weight detection module (200), and to determine the final weight (final weight) and weight distribution.

[0060] Specifically, the weight analysis module (300) comprises a center of mass (CoM) tracking unit (310) that continuously tracks the real-time center of mass (CoM) coordinates of a quadrupedal animal located on the device body (100) by synthesizing detection signals (detection data) from each section sensor module (210 to 240) of the weight detection module (200); a final weight determination unit (320) that determines the final weight by determining the section where the movement speed or fluctuation range of the center of mass (CoM) is maintained below a preset threshold value (e.g., 2 mm / sec or less) as the most stable section using the center of mass tracking information tracked by the center of mass tracking unit (310); and a distribution analysis unit (330) that analyzes the weight distribution by limb by calculating the percentage of weight borne on each of the front left and right and rear left and right limbs (i.e., the percentage of weight borne on each of the front left, front right, rear left, and rear right sides) based on the data or determination result determined by the final weight determination unit (320). Includes.

[0061] The above final weight determination unit (320) may be configured to determine the average value or median value of the data measured during the interval in which the movement speed or fluctuation range of the center of weight (CoM) is maintained below a preset threshold as the final weight and distribution data.

[0062] The above distribution analysis unit (330) converts the load of each section sensor module (210 to 240) into a ratio (%) relative to the total weight, calculates the front front-back weight distribution and left-right weight distribution, that is, the weight distribution applied in each of the front-left, front-right, rear-left, and rear-right sides, and calculates and analyzes the weight ratio by limb based on the relative distribution of each section sensor module.

[0063] In addition, the weight analysis module (300) in the present invention may further include a noise filtering unit (340) for removing or mitigating noise in sensor signals, including micro-shaking, heel movement, muscle vibration, and micro-vibration of the platform (pad member) itself, which are generated by a quadrupedal animal on the device.

[0064] Specifically, the noise filtering unit (340) is configured to perform at least one of noise removal using a moving average filter or a low-pass filter, exclusion of outliers through spike removal, zero point correction for sensor offset removal, and unit correction by applying a sensor-specific scale factor on raw load signals collected from each section sensor module (210 to 240), so that the load value of each section sensor module is converted into a stable weight value. The corrected signal is used for final weight calculation and weight distribution calculation.

[0065] In one embodiment, the noise filtering unit (340) may be configured to reduce instantaneous sudden changes (spikes) by averaging the measured values ​​over a short time interval using a moving average filter (or smoothing filter).

[0066] For example, it can be configured to filter into a smoothed output value according to the equation below.

[0067]

[0068] M: Window length (e.g., 5–20 samples)

[0069] x[n]: Raw sensor data

[0070] y[n]: Smoothed output value

[0071] Window Length refers to the number of consecutive data samples included when calculating the average, and k is an index indicating how far back the data is referenced from the current point n within the window. In other words, it refers to the data located k positions backward from n, centered around the current sample x[n].

[0072] The above noise filtering unit (340) can remove noise caused by the fine movements of quadruped animals and remove instantaneous spikes of the sensor.

[0073] In the weight measuring device for a quadruped animal according to the present invention described above, when a quadruped animal steps onto the device on all four legs, four sensor modules (210 to 240) measure the load at each point in real time.

[0074] And after collecting sensor data, the weight analysis module (300) applies noise removal and fine movement correction (if additionally including a noise filtering unit (340)) to stabilize the fluctuation of individual sensor module values.

[0075] Subsequently, the weight analysis module (300) determines a section where the change in value over a certain period is stable as a reliable section, and determines the final weight based on the average value of that section. From the determined weight and the load values ​​per sensor, the total weight, the front / rear weight ratio, the left / right weight ratio, and the weight proportion per limb are calculated. The calculated values ​​are displayed on the display unit (420) of the control module (400) in the form of digital numbers, circular or bar graphs, heat maps, etc.

[0076] Next, the control module (400) is a component configured to include a display unit (420) configured to visually provide the user with the on / off status of the device and the results analyzed by the weight analysis module (300).

[0077] Specifically, the control module (400) includes a device on / off unit (410) and a display unit (420) that displays the final weight (total weight) determined by the final weight determination unit (220), the front-back weight distribution ratio, and the left-right weight distribution ratio (i.e., the weight distribution ratios of the front-left, front-right, rear-left, and rear-right sides). In addition, the control module (400) may further include a communication module unit (430) and a communication status display unit (440) that enable interaction with an external device (mobile device or external server).

[0078] The above display unit (420) may be configured to display weight values ​​or graphic heatmaps for each section sensor module.

[0079] The communication module (430) is a component configured to transmit the results analyzed by the weight analysis module (300) to a mobile device (a smartphone with a linked application installed) or an external server.

[0080] In the present invention, 'communication', 'communication network', and 'network' by the communication module (430) refer to wired and wireless short-range and wide-range data transmission and reception networks capable of transmitting and receiving information (analysis results) between a user terminal, other users' terminals, and a download server.

[0081] For example, the communication module (430) may be configured as a short-range communication module using a PAN (Personal Area Network) method, such as BLE (Bluetooth Low Energy) or Bluetooth, Zigbee, UWB (Ultra-WideBand), ANT, or Wi-Fi, and may be configured to receive the analysis results of the weight analysis module (300) and transmit them to a device with communication functions installed, such as a smartphone or tablet PC, which has a linked application installed.

[0082] In addition, the communication module (430) may be configured to be transmitted to a remote external server via a known wired or wireless communication network.

[0083] Additionally, the control module (400) includes a battery unit (450), the battery unit (450) may be a replaceable battery, a rechargeable battery, and / or may be configured to receive power through a power cable connected to a power grid.

[0084] The weight measuring device for quadrupedal animals according to the present invention described above can be utilized in veterinary diagnosis and clinical fields, animal rehabilitation treatment fields, pet health management and wellness, and the development of precision medical devices for animals by measuring the weight and weight distribution of quadrupedal animals, including dogs, much more precisely and objectively than conventional methods.

[0085] Specifically, the present invention can determine an accurate final weight without error by correcting for minute weight fluctuations even in an environment where the animal is moving, and quantitatively analyzes the percentage (%) of weight distribution by limb (front, back, left, and right) to serve as a key indicator for objectively diagnosing and early detection of early-stage lameness (limping), musculoskeletal diseases (patellar luxation, hip dysplasia, etc.), and weight-bearing asymmetry caused by neurological problems that are difficult to confirm with the naked eye ("Veterinary Diagnosis and Clinical Fields").

[0086] In addition, the present invention can monitor changes before and after treatment in objective numerical terms by periodically measuring the degree of load on the affected area and weight shifting patterns of animals after surgery or during rehabilitation treatment, thereby verifying the effectiveness of rehabilitation treatment and providing quantitative data essential for precisely adjusting the intensity and direction of rehabilitation programs (e.g., physical therapy, exercise) (in the field of animal rehabilitation treatment).

[0087] In addition, the present invention enables guardians to easily perform regular weight and distribution checks on their animals at home, helping to detect abnormal weight bearing patterns early before symptoms of disease appear and predict when veterinary intervention is needed, and is effective for managing obesity or precisely tracking weight changes due to changes in nutritional status (pet health management and wellness).

[0088] In addition, the present invention provides accurate and highly reliable static weight distribution data, which can be utilized as key basic data for performance verification and validity evaluation when developing new diagnostic equipment or treatment techniques for animals (e.g., custom assistive devices, prosthetics) (development of precision medical devices for animals).

[0089] According to the weight measuring device for quadrupedal animals according to the present invention as described above, the present invention has the advantage of being able to measure the weight of quadrupedal animals, including dogs and cats, and to measure the weight accurately by minimizing the weight measurement error caused by the movement of quadrupedal animals.

[0090] In addition, the present invention can quantitatively analyze the weight distribution in the front, back, left, and right directions using a sensor module with multiple measurement areas suitable for quadrupedal animals, thereby effectively determining whether there is an abnormal posture or deviation in the animal. The weight and distribution results are displayed as intuitive results, such as in the form of a graph or a part indicator, making them easy for any user to understand and utilize. Furthermore, the structure is simple and compact, allowing it to be applied to various environments such as homes, veterinary hospitals, and rehabilitation centers, thus providing the advantage of versatility.

[0091] Furthermore, the present invention has the advantage of being able to be utilized in the veterinary field to objectively diagnose early lameness and musculoskeletal disorders and diseases, such as patellar luxation, fractures, and ligament injuries, by precisely determining the final body weight despite the animal's movement and quantitatively analyzing the weight distribution of the front, back, left, and right ligaments; to quantitatively monitor the recovery progress and adjust treatment plans during animal rehabilitation; to support the health management of pets by owners to detect potential health problems early; and to be widely used as reliable basic data for the development of precision medical devices for animals.
