A SHOE INSOLE
TECHNICAL FIELD
[0001] The present invention relates to a shoe insole for correcting gait abnormalities and addressing misalignment and abnormalities in foot movement during walking or running. Most particularly, the invention aims to provide 5 improved support, stability, and comfort for users, thereby enhancing their walking posture and reducing the risk of injury associated with improper gait.
BACKGROUND
[0002] Foot landing is a pivotal aspect of gait biomechanics, significantly influencing overall movement efficiency and stability. Proper foot landing patterns 10 are essential to maintain balance and minimize the risk of injury. Conversely, incorrect foot landing can lead to a range of musculoskeletal injuries, including plantar fasciitis, shin splints, and knee pain. The increasing prevalence of gait abnormalities necessitates innovative solutions to address these issues effectively. Current footwear options, including traditional orthotic inserts and various smart 15 technologies, often fall short of providing real-time feedback to users. This gap in the market highlights the need for a novel approach that not only supports the foot but also actively guides the user towards healthier gait patterns.
[0003] Traditional orthotic inserts, which can be either custom-molded or off-the-shelf, are designed primarily to provide structural support and correct foot 20 alignment. While these inserts can be beneficial in addressing certain foot conditions, they come with significant limitations. A notable disadvantage is their lack of real-time feedback; users often wear these inserts without any immediate indication of their foot landing patterns. Additionally, the fitting process for custom inserts often requires professional assistance, and any necessary adjustments are 25 static rather than dynamic. These inserts cannot adapt to changing gait patterns over time, reducing their effectiveness in the long run. Existing patents in this category, such as U.S. Patent No. 4,072,151 for orthopedic insoles and U.S. Patent No.
3
5,195,208 for adjustable orthotic inserts, emphasize structural support without incorporating responsive feedback mechanisms.
[0004] The advent of wearable sensors and smart insoles represents another approach to monitoring foot pressure and gait patterns. These devices are typically equipped with sensors that collect data, which can then be transmitted to a 5 connected device for analysis. However, a significant drawback of many smart insole systems is their failure to provide immediate, actionable feedback, such as sound or haptic alerts. Moreover, these devices can be bulky and uncomfortable, often requiring users to carry additional devices like smartphones for data interpretation. Notable patents in this domain include U.S. Patent No. 8,006,621, 10 which outlines a system for monitoring gait, and U.S. Patent No. 9,226,709, which describes footwear with integrated sensors. Both highlight the importance of gait analysis, yet neither addresses the immediate feedback that is crucial for effective gait correction.
[0005] Visual feedback systems, which utilize cameras and software to analyze 15 gait, have also been developed. While these systems can offer valuable insights into gait mechanics, they require complex setups and calibration, making them impractical for everyday use. Feedback is often provided post-analysis, which diminishes its effectiveness in real-time correction scenarios. U.S. Patent No. 6,503,183 exemplifies this approach but underscores the limitations inherent in 20 non-portable systems that lack immediacy.
[0006] Haptic feedback devices, which provide tactile signals to users to indicate incorrect gait patterns, present another alternative. While they can alert users to issues, the feedback can be non-intuitive and easily ignored. Additionally, the customization required for effective use can be extensive, and some users may find 25 continuous wear uncomfortable. U.S. Patent No. 8,808,337 discusses a wearable haptic feedback system for gait training but highlights the need for a more user-friendly and intuitive solution.
4
[0007] Footwear with embedded technologies is another innovative approach, featuring built-in sensors and feedback mechanisms designed to monitor and correct gait. However, these systems are often limited to specific shoe models, which can be a barrier for users who prefer different footwear styles. High costs and potential bulkiness further complicate their accessibility and comfort. U.S. 5 Patent No. 9,848,369 describes a smart shoe for gait analysis, yet it emphasizes the challenges of adapting to varied user preferences and the physical demands of daily life.
[0008] Overall, the existing approaches to gait correction and injury prevention reveal several common disadvantages: the lack of immediate feedback, comfort and 10 usability issues, complexity in setup and usage, and limited customization options. These shortcomings highlight a pressing need for innovative solutions that can effectively support users in real time while remaining comfortable and user-friendly.
[0009] Thus, addressing these problems, the proposed a shoe insole for correcting 15 gait abnormalities addresses traditional challenges by providing real-time sound feedback aims to fill this gap, offering an accessible, dynamic solution for correcting gait patterns and preventing injuries. By addressing the deficiencies of current products, this invention seeks to enhance overall foot health and mobility, empowering users to engage in daily activities with greater confidence and reduced 20 risk of injury.

[0043] Gait abnormalities can significantly impact a person's overall health and mobility, leading to discomfort and potential injuries. Traditional methods for addressing these issues often lack the immediacy and adaptability required for 15 effective correction. Our innovative shoe insert aims to fill this gap by integrating advanced sensor technology with a real-time auditory feedback system. This document outlines the design, functionality, benefits, and potential applications of the shoe insert, emphasizing its role in improving gait mechanics and preventing injuries. 20
[0044] Referring to Figure 1 illustrates, a shoe insole consists of an enclosure made up of several layers, ensuring comfort and housing various electronic components. The enclosure includes a top layer, which serves as the interface with the user's foot, providing a soft surface for comfort. Beneath the top layer is the first intermediate layer, which accommodates the sensing module. This layer is followed 25 by the second intermediate layer, where the electronics module is placed. Finally, there is a base layer that provides structural support, ensuring the insole's durability.
11
The layers are engineered to integrate the necessary electronics while maintaining flexibility and comfort for the user.
[0045] The sensing module is embedded within the first intermediate layer of the insole, designed to detect pressure distribution across different points of the foot. It includes an array of pressure sensors, strategically positioned to capture variations 5 in foot pressure during movement. These sensors can be of capacitive or piezoelectric types, providing high sensitivity to pressure changes. Additionally, the sensing module is equipped with angle sensors, such as inertial measurement units (IMUs), to measure the orientation of the foot, allowing accurate detection of foot angles during various phases of walking or running. 10
[0046] Located in the second intermediate layer, the electronics module integrates a microcontroller, a Bluetooth module, and a battery. The microcontroller, which is a low-power ARM Cortex-M series processor, processes real-time data from the sensing module, analyzing pressure distribution and foot angles to detect gait abnormalities. The Bluetooth module enables wireless transmission of the 15 processed data to a paired mobile device for further analysis, visualization, or monitoring by the user. A compact battery, such as a coin cell battery, powers the microcontroller and other electronic components, providing sufficient energy for extended use while keeping the insole lightweight.
[0047] The sound feedback module is integrated into the enclosure and is capable 20 of generating auditory signals based on the data received from the sensors. This module includes a miniature speaker or buzzer that produces sounds to alert the user of detected gait abnormalities. The volume of the feedback can be adjusted to suit the user's preference, ensuring that the sound is audible without being disruptive. The feedback is real-time, allowing users to correct their gait while 25 walking or running.
[0048] The adjustable sensitivity module is designed to provide users with the flexibility to customize the feedback response based on their unique gait characteristics. This feature can be controlled through a companion mobile
12
application, which allows users to set preferred sensitivity levels for detecting deviations in pressure or foot orientation. By adjusting the sensitivity, users can tailor the system's response to their needs, making the insole suitable for a wide range of users, from those with minor gait issues to those needing more precise feedback. 5
[0049] The power supply unit is incorporated within the enclosure, providing electricity to all the electronic components. It includes a coin cell battery, chosen for its compact size and lightweight properties, making it ideal for use in a shoe insole. The battery is designed to last several weeks under typical usage conditions, ensuring that users do not have to frequently recharge or replace it. This power-10 efficient design supports the insole's goal of being a practical, everyday solution for gait correction.
[0050] The pressure sensor array within the sensing module consists of 5 to 7 sensors strategically placed across the foot area. These sensors may include capacitive or piezoelectric types, capable of accurately detecting pressure variations 15 at critical points such as the heel, arch, and forefoot. The strategic placement ensures a comprehensive understanding of the user's weight distribution, helping to identify abnormalities such as overpronation or underpronation.
[0051] The insole utilizes a combination of capacitive pressure sensors and inertial measurement unit (IMU) sensors for a thorough analysis of gait patterns. While the 20 capacitive sensors detect pressure points, the IMUs measure the angular movement of the foot. This combination allows for the detection of not only the pressure exerted but also the orientation and movement dynamics of the foot, providing a detailed picture of the user's gait. The angle sensor comprises IMUs, which include accelerometers and gyroscopes for precise foot angle detection. The accelerometers 25 measure the linear acceleration of the foot, while the gyroscopes detect rotational movements. Together, they enable the accurate measurement of the foot's angle during different phases of the gait cycle, allowing the insole to detect deviations that may indicate abnormalities in walking or running patterns.
13
[0052] The Bluetooth module within the electronics module enables the insole to wirelessly communicate with a paired mobile device. This feature allows real-time transmission of sensor data, making it possible for users to access detailed analysis and visualization of their gait patterns through a dedicated app. The app can display pressure maps, angle measurements, and provide feedback on gait corrections, 5 making the insole an intelligent and interactive device.
[0053] The microcontroller, an ARM Cortex-M series processor, manages the data processing tasks within the insole. It processes the input from the pressure sensors and IMUs, identifies gait anomalies, and triggers the sound feedback module accordingly. Designed for low power consumption, the microcontroller ensures 10 efficient operation without significantly draining the battery, making the insole suitable for prolonged use.
[0054] The enclosure of the insole is constructed from lightweight, durable materials that ensure a comfortable fit within various types of footwear. It is designed to withstand the pressure and stresses of regular walking or running while 15 maintaining its structural integrity. The use of such materials ensures that the insole remains comfortable for the user while protecting the embedded electronics, making it suitable for daily wear.The adjustable sensitivity module can be operated through a mobile application that pairs with the insole via Bluetooth. This app allows users to easily set the sensitivity levels for pressure detection and feedback 20 response, catering to individual gait requirements. The user-friendly interface ensures that even those with minimal technical knowledge can effectively use the insole to improve their walking or running patterns.The power supply unit relies on a coin cell battery, chosen for its compact size and ability to provide long-lasting power. This type of battery is suitable for portable devices like the insole, as it 25 ensures a balance between battery life and minimal weight addition. With proper energy management, the coin cell battery can last for several weeks, reducing the need for frequent replacements or charging.
14
[0055] The design of the gait-correcting shoe insole addresses a pressing need in the realm of injury prevention and gait correction. By fusing advanced sensor technology with a responsive sound feedback system, the insert not only enhances foot landing mechanics but also offers users a customizable experience tailored to their unique needs. The lightweight and comfortable design ensures usability across 5 various types of footwear, making it an essential tool for athletes, rehabilitation patients, and anyone aiming to improve their gait biomechanics. In seeking to patent this innovative design, we aim to protect our intellectual property while facilitating the market introduction of this groundbreaking product. By bringing the shoe insert to market, we aspire to benefit individuals and healthcare professionals alike, 10 ultimately improving foot health and biomechanics for a wide audience. Our commitment to innovation and user-centric design positions this shoe insole as a vital resource for enhancing mobility and preventing injuries, promoting a healthier and more active lifestyle for users of all ages.
