Description

Technical Field

[0001] The present invention relates to the technical field of customization of foot pain therapy insoles, and in particular to a personalized customization method and system of foot pain therapy insoles. Background Art

[0002] Traditional methods typically use fixed designs and inflation patterns, and are unable to dynamically adjust support based on changes in the user's gait. A user's gait may change due to exercise, fatigue, or the passage of time, but traditional insoles cannot sense these changes in real time and make corresponding adjustments, thus failing to provide precise, comfortable support. Traditional methods often fail to provide personalized adjustments based on the user's specific gait characteristics (such as heel strike, midfoot strike, forefoot strike, etc.). Their designs are usually uniform and do not consider the airflow and pressure distribution requirements of different gaits, resulting in potentially insufficient comfort and support. Traditional methods often lack airflow circulation channel designs, and the airflow distribution and adjustment are static, which cannot effectively adjust pressure flow to balance the burden on different areas. Summary of the Invention

[0026] Setting a relatively comfortable preset pressure peak value based on historical plantar pressure data, and comparing the plantar pressure peak value with the preset pressure peak value;

[0027] When the plantar pressure peak reaches the preset pressure peak, the inflation of the primary airbag and the secondary airbag is stopped to obtain the primary airbag and the secondary airbag with initialized inflation volumes.

[0028] Preferably, dynamically adjusting the inflation rate of the initial circulation gas diversion channel based on the real-time plantar pressure data includes:

[0029] When the real-time plantar pressure data is higher than the preset threshold, the inflation rate of the airbags in the high-pressure area is automatically reduced, while the inflation rate of the airbags in the low-pressure area is increased, so as to achieve pressure balance of the insole;

[0030] Based on the pressure balance, it is ensured that the user feels uniform and comfortable support when walking, running or standing, so as to achieve a therapeutic effect for foot pain.

[0041] Example 1, as Figure 1 As shown, the present invention proposes a personalized customization method for a foot pain therapy insole, comprising:

[0042] S1. Dynamically collecting plantar pressure distribution during a user's natural gait cycle based on a pressure sensor array integrated in the insole to obtain plantar pressure distribution data;

[0043] S2. extracting pressure intensity features from the plantar pressure distribution data to obtain a landing style category of the user, where the landing style categories include heel landing, midfoot landing, and forefoot landing;

[0044] S3. Constructing a one-way airbag diversion channel for the corresponding landing area of ​​the insole based on the landing mode category to obtain a circulating air diversion channel from the forefoot to the midfoot and then back to the rearfoot, wherein the circulating air diversion channel includes a one-way valve, a primary airbag, and a secondary airbag;

[0045] S4. Obtaining a plantar pressure peak value based on the plantar pressure distribution data, and initializing the opening time of the one-way valve, the inflation volume of the primary airbag, and the inflation volume of the secondary airbag based on the plantar pressure peak value to obtain an initial circulating gas diversion channel;

[0046] S5. Acquire real-time plantar pressure data, and dynamically adjust the inflation rate of the initial circulation gas diversion channel based on the real-time plantar pressure data. When the real-time plantar pressure data exceeds a preset threshold, reduce the inflation rate of the airbag in the corresponding area of ​​the initial circulation gas diversion channel to transfer the gas in the high-pressure area of ​​the insole to the low-pressure area.

[0047] In the present invention, the pressure sensor array refers to a sensor grid integrated inside the insole, which is used to detect and collect plantar pressure distribution data of the user during walking; the natural gait cycle refers to the gait pattern of a person's body in a normal motion state when walking or standing, usually involving processes such as landing, supporting and lifting the foot; the plantar pressure distribution refers to the distribution of pressure values ​​in various parts of the plantar during the gait cycle, which can be measured and analyzed by the sensor array; pressure intensity feature extraction refers to extracting representative features, such as pressure peak, from the collected plantar pressure data; the circulating gas diversion channel refers to the channel through which gas flows from one area to another inside the insole, usually in conjunction with airbags and valves to achieve dynamic regulation of plantar pressure; the main airbag is mainly responsible for regulating the air pressure in the insole and helping to adjust the pressure distribution on the plantar; the secondary airbag refers to assisting the main airbag in its work and is usually used to adjust the air pressure in a local area; the plantar pressure peak refers to the maximum value in the plantar pressure distribution, usually reflecting the degree of pressure concentration in a certain part when walking or standing; inflation rate adjustment refers to dynamically adjusting the airbag inflation speed based on the real-time collected plantar pressure data to achieve comfort and pressure balance.

[0048] Example 2, a method for customizing a foot pain therapy insole according to the present invention, compared to Example 1, further includes:

[0049] A1. Dynamically collect the plantar pressure distribution during the user's natural gait cycle based on the pressure sensor array integrated in the insole, including:

[0050] A2. Evenly distribute multiple high-precision pressure sensors on the bottom of the insole;

[0051] A3. Based on high-precision pressure sensors, the plantar pressure changes of users when walking, running or standing are captured in real time to obtain plantar pressure distribution data.

[0052] In this embodiment, the high-precision pressure sensor refers to a sensor with high measurement accuracy, which is used to capture tiny pressure changes and ensure the accuracy of plantar pressure data. They can reflect the pressure distribution of each area in detail.

[0053] In an optional embodiment, pressure intensity features are extracted from the plantar pressure distribution data to obtain the user's landing style category, including:

[0054] B1. Extracting features from the plantar pressure distribution data based on a clustering algorithm to obtain a pressure intensity feature vector of the plantar pressure distribution data;

[0055] B2. Classify the user's landing method based on the pressure intensity feature vector to obtain the user's landing method category.

[0056] It should be noted that the clustering algorithm refers to dividing the data set into different groups so that the data within the same group is more similar, while the data between different groups are more different; the pressure intensity feature vector refers to a multidimensional numerical vector obtained by feature extraction of the plantar pressure distribution data. This vector contains information describing the characteristics of the plantar pressure distribution, such as the pressure intensity in different areas.

[0057] In an optional embodiment, feature extraction is performed on the plantar pressure distribution data based on a clustering algorithm to obtain a pressure intensity feature vector of the plantar pressure distribution data, including:

[0058] C1. Clustering the plantar pressure distribution data based on a clustering algorithm to obtain the pressure intensity levels of different plantar areas;

[0059] C2. Constructing a pressure intensity feature vector based on the pressure intensity levels, wherein the pressure intensity feature vector includes the pressure intensity levels and corresponding pressure values ​​of different sole areas.

[0060] It should be noted that pressure intensity levels refer to the classification of pressure intensity in different regions obtained through a clustering algorithm. By clustering the plantar pressure distribution data, different regions of the plantar can be identified and each region can be assigned a pressure intensity level based on the pressure intensity. For example, the plantar can be divided into several regions (such as the forefoot, midfoot, and heel), and the pressure value in each region can be classified into low, medium, and high pressure intensity levels.

[0061] In an optional embodiment, a one-way airbag guide channel is constructed for the corresponding landing area of ​​the insole based on the landing mode category to obtain a circulating air guide channel from the forefoot to the midfoot and then back to the rearfoot, including:

[0062] D1. When the landing mode is heel strike, a primary airbag is provided in the rearfoot area of ​​the insole, and secondary airbags are provided in the midfoot and forefoot areas of the insole;

[0063] D2. When the landing mode is midfoot landing, a primary airbag is provided in the midfoot area of ​​the insole, and a secondary airbag is provided in the forefoot area of ​​the insole;

[0064] D3. When the landing mode is forefoot landing, a primary airbag is provided in the forefoot area of ​​the insole, and a secondary airbag is provided in the midfoot area of ​​the insole;

[0065] D4. Based on the above steps, a gas conduction path is formed from the forefoot to the midfoot and then back to the hindfoot to obtain a circulating gas diversion channel.

[0066] It's important to note that a gas conduction path refers to the route that gas takes between the air cells. To regulate pressure in different areas of the sole, gas flows between the air cells, forming a specific gas conduction path. This path design helps direct pressure from higher-pressure areas to lower-pressure areas, thereby balancing pressure distribution on the sole of the foot and improving comfort.

[0067] In an optional embodiment, the primary airbag and the secondary airbag are connected via a one-way valve, so that the gas flows from one airbag to the other, forming a one-way flow guide.

[0068] In an optional embodiment, the opening time of the one-way valve, the inflation amount of the primary airbag, and the inflation amount of the secondary airbag are initialized based on the peak value of the plantar pressure, including:

[0069] E1. Set a comfortable preset pressure peak based on historical plantar pressure data and compare the plantar pressure peak with the preset pressure peak;

[0070] E2. When the plantar pressure peak reaches a preset pressure peak, the inflation of the primary airbag and the secondary airbag is stopped to obtain the primary airbag and the secondary airbag with initialized inflation volumes.

[0071] It should be noted that historical plantar pressure data refers to the user's plantar pressure distribution data collected and recorded over a long period of time. These data reflect the user's plantar pressure during activities such as walking and running at different times and environments. Historical data helps to analyze and understand the user's plantar pressure distribution pattern and provide a reference for future pressure regulation.

[0072] In an optional embodiment, dynamically adjusting the inflation rate of the initial circulation gas diversion channel based on real-time plantar pressure data includes:

[0073] F1: When the real-time plantar pressure data exceeds the preset threshold, the inflation rate of the airbags in the high-pressure area is automatically reduced, while the inflation rate of the airbags in the low-pressure area is increased to achieve pressure balance in the insole;

[0074] F2. Based on pressure balance, it ensures that users feel uniform and comfortable support when walking, running or standing, so as to achieve the therapeutic effect of foot pain.

[0075] It should be noted that the preset threshold refers to the pressure upper limit set in advance based on historical data and human comfort standards. When the real-time plantar pressure data exceeds this threshold, it means that the pressure in certain areas is too high and needs to be adjusted to avoid discomfort or injury; the pressure balance of the insole refers to adjusting the inflation rate of the airbags in different areas to achieve relative balance of pressure in various areas of the sole, avoid excessive pressure concentration at a certain point, make the overall force on the sole more uniform, and improve comfort and stability. The foot pain therapy effect refers to reducing or alleviating pain caused by pressure concentration, foot fatigue or injury by adjusting the airbag pressure, thereby achieving protection and treatment auxiliary functions for the foot and promoting foot health.

[0076] Example 3, as Figure 2 As shown, the present invention proposes a personalized customization system for a foot pain therapy insole, which is applicable to a personalized customization method for a foot pain therapy insole, including:

[0077] The pressure acquisition unit 1 is used to dynamically acquire the plantar pressure distribution during the user's natural gait cycle based on the pressure sensor array integrated in the insole to obtain plantar pressure distribution data;

[0078] Landing category unit 2, which is used to extract pressure intensity features from the plantar pressure distribution data to obtain the user's landing mode category, where the landing mode categories include heel landing, midfoot landing, and forefoot landing;

[0079] Airbag construction unit 3, which is used to construct a one-way airbag diversion channel for the corresponding landing area of ​​the insole based on the landing mode category, so as to obtain a circulating gas diversion channel from the forefoot to the midfoot and then back to the rearfoot, wherein the circulating gas diversion channel includes a one-way valve, a primary airbag, and a secondary airbag;

[0080] The airbag inflation unit 4 is used to obtain the peak plantar pressure based on the plantar pressure distribution data, and initialize the opening time of the one-way valve, the inflation volume of the primary airbag, and the inflation volume of the secondary airbag based on the plantar pressure peak to obtain an initial circulating gas diversion channel;

[0081] The pressure relief unit 5 is used to obtain real-time plantar pressure data and dynamically adjust the inflation rate of the initial circulation gas diversion channel based on the real-time plantar pressure data. When the real-time plantar pressure data exceeds a preset threshold, the inflation rate of the airbag in the corresponding area of ​​the initial circulation gas diversion channel is reduced to transfer the gas in the high-pressure area of ​​the insole to the low-pressure area.
