DETAILED DESCRIPTION

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] To address the shortcomings of existing technologies, the present invention provides an intelligent waist support belt for diet management. Through a pressure sensor, heart rate sensor, inertial measurement unit (IMU), and air pressure feedback module, it monitors the user's food intake in real time, dynamically adjusts the tightness of the belt, and provides embodied physical feedback. Furthermore, a mobile phone app provides mindfulness guidance and emotion-driven artistic feedback (such as dynamic canvases and sound effects), assisting users in controlling their eating behavior and preventing excessive intake. The belt is suitable for people trying to lose weight, patients with chronic diseases, and those with a strong health consciousness.

[0017] In the embodiment, the strap body 100 is made of elastic fabric, has a width of 5 cm and a length of 80-120 cm, and is used to be wrapped around the user's waist, close to the stomach.

[0018] The data acquisition module 1 is installed inside the strap body 100 and is used to monitor abdominal pressure, heart rate changes and chewing movements through sensors.

[0019] like Figure 2 As shown, the data acquisition module 1 includes: a pressure sensor 11 , a heart rate sensor 12 and an inertial measurement unit 13 .

[0020] The pressure sensor 11 is embedded inside the bandage body 100, close to the abdomen, and is used to monitor pressure changes caused by stomach expansion.

[0022] The heart rate sensor 12 is embedded in the inner side of the strap body 100 and attached to the skin to monitor changes in heart rate during eating.

[0023] In the embodiment, the heart rate sensor 12 is of model MAX30102.

[0024] The inertial measurement unit 13 is installed on the outside of the strap body 100 and is used to monitor chewing movements or head movements.

[0025] In the embodiment, the model of the inertial measurement unit 13 is: MPU6050.

[0026] The microcontroller module 2 is installed outside the strap body 100 and is used to process sensor data, determine food intake, and control air pressure feedback and tactile / visual feedback.

[0027] In the embodiment, the micro-control module 2 is a microcontroller 21 , model: Arduino Nano.

[0028] The air pressure feedback module 3 is installed on the inner and outer sides of the strap body 100 and is used to dynamically adjust the tightness of the strap body 100 and simulate the body shape of obesity after overeating.

[0029] In the embodiment, the air pressure feedback module 3 includes: a micro air pump 31 and a silicone air bag 32. The micro air pump 31 is of model: DCMicroAirPump, and the size of the silicone air bag 32 is: 5 cm×3 cm.

[0030] The micro-control module 2 is connected to the micro-air pump 31 through a MOSFET, and the micro-air pump 31 is connected to the silicone airbag 32. The micro-control module 2 is used to control the micro-air pump 31 to generate air pressure, thereby causing the silicone airbag 32 to expand or contract. For example, when the sensor detects excessive intake (pressure value > 500 and heart rate > 80), the micro-control module 2 triggers the micro-air pump 31 and provides sensory feedback.

[0031] In an embodiment, the silica gel air bag 32 includes a silica gel air bag mounted on the inner side of the belt body 100 and a silica gel air bag mounted on the outer side of the belt body 100, wherein, The silica gel air bag mounted on the inner side of the belt body 100 at the abdomen is used to dynamically adjust the tightness of the belt body 100, thereby providing feedback to the user's eating. The silica gel air bag mounted on the outer side of the belt body 100 at the abdomen is used to simulate the body shape after overeating, so that the user can know the future change in advance and control the eating habits.

[0032] In an embodiment, the waist support belt can also adjust the pressure and support of the user's waist through the silica gel air bag 32, thereby playing the role of waist protection.

[0033] The feedback module 4 is mounted on the outer side of the belt body 100, and is used to provide tactile and visual feedback through the vibration motor 41 and the LED lamp 42.

[0034] In an embodiment, the vibration motor 41 is a 10mm flat vibration motor, and the LED lamp 42 is a WS2812B.

[0035] The wireless communication module 5 is mounted on the outer side of the belt body 100, and is used to communicate with the mobile phone APP, transmit eating data, and provide mindfulness guidance and artistic feedback.

[0036] In an embodiment, the wireless communication module 5 is an HC-05 Bluetooth module 51, which communicates with the mobile phone APP, provides mindfulness guidance (such as "slow down and feel full"), and provides dynamic canvas feedback based on heart rate (such as dynamic canvas based on heart rate).

[0037] The API interface 6 is used to connect to a computer, analyze the data of the user after a period of use according to the AI algorithm embedded on the computer, determine the time period when the user is likely to eat, take preventive measures in advance, and generate a prevention plan, which is fed back to the micro control module 2. The micro control module 2 generates control instructions according to the prevention plan; for example, if the user has the habit of having a snack at night, the micro control module 2 will control the micro air pump 31 to generate air pressure, thereby causing the silica gel air bag 32 to expand and reminding the user not to eat.

[0038] Working principle: When the user wears the belt body 100 to eat, the pressure sensor 11 monitors the change of abdominal pressure, the heart rate sensor 12 detects physiological changes, and the inertial measurement unit 13 detects chewing actions.

[0039] Microcontroller module 2 analyzes the data to determine if food intake exceeds the recommended limit. This triggers air pressure feedback (tightening of silicone airbag 32 inside strap body 100), vibration of vibration motor 41, and LED light 42 to remind the user to control their diet. Silicone airbag 32 outside strap body 100 simulates the appearance of weight gain after overeating, allowing the user to anticipate future changes and manage their diet accordingly. A mobile app displays intake data in real time, providing personalized dietary recommendations and artistic feedback. Specific embodiment: In a family dining scenario, the user wears the strap body 100. The pressure sensor 11 detects that the stomach pressure exceeds the threshold (500), and the heart rate sensor 12 detects that the heart rate exceeds 80 BPM. The microcontroller module 2 triggers the micro air pump 31 (PWM value 200), and the silicone airbag 32 inside the strap body 100 tightens. The vibration motor 41 and LED light 42 are activated simultaneously to remind the user to stop eating. The silicone airbag 32 outside the strap body 100 simulates the body shape of obesity after overeating, allowing the user to know the future changes in advance and control their eating habits. The mobile phone app pushes mindfulness reminders and dynamic canvas to enhance the eating experience.

[0041] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
