Description:FIELD OF THE INVENTION
[0001] The present invention relates to the field of yoga science, and more particularly, the present invention relates to the sensor-based postural correction meditation chair.
BACKGROUND FOR THE INVENTION:
[0002] The following discussion of the background to the invention is intended to facilitate an understanding of the present invention. However, it should be appreciated that the discussion is not an acknowledgment or admission that any of the material referred to was published, known, or part of the common general knowledge in any jurisdiction as of the priority date of the application. The details provided herein the background if belongs to any publication is taken only as a reference for describing the problems, in general terminologies or principles or both of science and technology in the associated prior art.
[0003] The importance of correct posture during meditation has been emphasized for centuries in both yogic and classical traditions. In the Bhagavad Gita, in the verse “Samam Kayashirogrivam Dharayanachalam Sthirah” (Chapter 6, Verses 12-13), Lord Krishna outlines the ideal conditions for meditation, highlighting the need for a steady, upright sitting posture conducive to mental concentration. He recommends that the practitioner should sit steadily, with the body, head and neck in a straight line. Similarly, the Yoga Sutras of Patanjali define asana as "sthira sukham asanam", which means "asana is a steady and comfortable posture". He emphasizes that asana should be a balance between stability and ease, allowing the practitioner to maintain the pose without any strain or discomfort. According to Patanjali, mastery of asana comes from rising above the fickle nature of the body and mind, making it possible to achieve a deep state of meditation and connection with inner experience. On this basis, it can be said that sitting upright in a stable and comfortable posture is considered essential in meditation and yoga practice. However, in meditation, maintaining the posture position for a long time is a struggle. A common problem is that their back gradually starts bending forward during meditation. Physical discomfort, back pain and distraction are common when repeated attempts are made - making it difficult to meditate for a long time.
[0004] To deal with this, people often lean against a wall or use meditation chairs for support. While these options provide temporary relief, they do not train the body to keep itself upright. In fact, over time, too much support can weaken the back muscles, leading to even more slouching. Many modern meditation chairs are designed for comfort only and fail to help users naturally maintain the correct sitting posture. When the user begins to lean forward beyond a threshold value and doesn’t return to the correct position within 5 seconds, the sensor detects it and sends a signal to the microcontroller. A shaft, having silicon pad on its top and attached to the system, then gently extends to touch the lower back. This gentle motion reminds the individual to sit upright without using force or sudden movement. As mentioned, the user can also set a timer via remote or mobile phone control before starting their practice. For example, after every 2 or 5 minutes, if the back has started to slouch, the chair will gently move it back to the upright position. This solution is gentle, non-distracting, and helps users develop muscle memory and self-awareness over time.
[0005] Unlike regular chairs or backrests, this invention doesn’t just support—it teaches. It provides a middle path between learning relaxation and alertness, helping beginners gradually develop the ability to sit upright without external help. In short, the invention addresses three major problems:
- Difficulty in maintaining upright posture during meditation.
- Excessive dependence on passive support, which makes the posture dependent and weak in the long run.
- Lack of real-time feedback or gentle correction during practice.
[0006] In light of the foregoing, there is a need for the sensor-based postural correction meditation chair that overcomes problems prevalent in the prior art.

[0017] Other objects and advantages of the present disclosure will be more apparent from the following description, which is not intended to limit the scope of the present disclosure.
SUMMARY OF THE INVENTION:
[0018] The present invention provides a sensor-based postural correction meditation chair. This invention is a specially designed meditation chair that helps people - especially beginners - to sit with a straight back during meditation, without having to constantly adjust their posture.
[0019] This invention is not just a regular meditation chair; it is a smart meditation chair designed to help users maintain the correct posture without any discomfort. Most meditation chairs nowadays only offer basic rests or back support, leading to slouching and poor posture when the body is relaxed. This invention is different because it uses a gentle, sensor-based system that detects when the user begins to slouch. Instead of interrupting the meditation with a buzz or alarm, the chair gently adjusts itself to encourage the user to sit upright again, without distracting their focus. For example, if lower back begins to lean forward during meditation, the chair returns to its original shape in a minute or two, helping you to gradually straighten up.
[0020] Another unique feature is the ability to control the chair’s correction settings via the mobile app or remote, allowing users to adjust the time and intensity of posture correction.
[0021] In simple terms, this chair acts like a calm and meditation teacher that gently reminds you to sit up straight, helping you learn better posture over time without interrupting meditation.
[0022] When people start meditating, they are usually asked to sit upright and steady in Sukhasana. However, many beginners find it difficult to keep their backs straight for more than a few minutes. Gradually, their upper backs (thoracic to lumbar) begin to bend forward, and they move from their starting position. To deal with this, some people lean against a wall or use regular meditation chairs. But these aids only provide support - they do not help the person learn to sit upright naturally. It is scientifically proven that using too much support can weaken the muscles over time. The backrest of meditation chair features a sensor-based device that monitors the lower back while sitting. This device uses a proximity sensor to detect the distance between the user’s lower back and the chair’s backrest. If the sensor detects that the user has leaned forward beyond a predetermined threshold for more than 5 seconds—indicating slouching or poor posture—it sends a signal to the controller, and a shaft mechanism gently extends to apply pressure to the lower back. This gentle feedback encourages the user to naturally return to an upright posture.
[0023] Apart from the proximity sensor system, the chair can also operate in a time-based reminder mode. This is especially useful during the initial days of practice, when a person may not be able to maintain a straight posture for more than 2 or 3 minutes at a time. In this mode, the shaft mechanism will gently push against the user's lower back at fixed intervals—such as every 2 or 5 minutes—regardless of posture detection. This periodic reminder helps the user gradually build awareness and strength to maintain proper posture over longer durations. The time-based reminder feature can be easily turned off using the remote control, giving the user full flexibility based on their comfort and progress.
[0024] This process helps them learn to stay in the right posture without need to think about it all the time. Over time, this chair helps people become more aware of how they sit and trains their body to stay upright on its own. This is important because good posture not only prevents back pain but also helps the mind stay alert and focused during meditation. In short, this meditation chair doesn’t just provide support – it teaches the body to sit better. It helps beginners improve their meditation without distractions and gradually builds their ability to sit upright and steady for long periods of time without relying on walls or other supports.
[0025] Additionally to ensure comfort, the shaft will be attached with a silicon pad so it will not harm or irritate the skin during gentle touch. To accommodate users of different heights, the shaft mechanism includes an adjustable height feature, allowing the user to set the shaft position so it aligns comfortably with their lower back.
[0026] The invention presents a meditation chair equipped with a sensor-based system embedded in the lower backrest. Such that this system:
- Monitors posture: Uses proximity sensor to detect the distance and curvature of the user's lower back.
- Detects slouching: Identifies when the user begins to slouch or bend beyond a predefined limit.
- Activates correction mechanism: Upon detecting slouching, a soft, self-controlled mechanism gently moves the lower back to its ideal position.
- User control: Allows the user to set a timer and adjust correction parameters via the mobile app or remote control.
[0027] This dynamic correction is designed to be non-intrusive and slow, preventing any sudden movements that may disrupt the meditative state.

[0037] The present invention provides a sensor-based postural correction meditation chair.
[0038] The invention relates to a posture-correcting system integrated into a meditation chair, designed to provide active feedback for maintaining proper spinal alignment during seated meditation. The system utilizes a proximity sensor, strategically positioned within the chair’s backrest, to monitor the distance between the user's body and the backrest surface. When the user leans forward beyond a predefined threshold distance and does not return to the correct posture within a set delay period (e.g., 5 seconds), the sensor sends a signal to a microcontroller unit (MCU).
[0039] Upon receiving this signal, the MCU activates a shaft mechanism embedded in the backrest. The shaft is equipped with a soft, skin-safe silicone pad at its tip to ensure a comfortable and non-irritating user experience. The shaft gently extends to apply light pressure to the user’s lower back area, serving as a tactile cue to promote the return to an upright sitting posture. The actuation is smooth and gradual, avoiding any sudden movements that could interrupt the meditative state.
[0040] In addition to sensor-based correction, the system includes an optional time-based reminder mode. This mode is beneficial during early stages of practice when maintaining consistent posture is more challenging. In this configuration, the shaft activates at fixed intervals—such as every 2 or 5 minutes—regardless of posture status. These intervals can be user-defined through a remote control or mobile application. The time-based reminder can be ON or OFF according to user preference and progress.
[0041] To ensure ergonomic compatibility for users of various heights, the shaft includes an adjustable vertical positioning mechanism. This feature allows precise alignment with the lower back, ensuring effective and comfortable feedback for a wide range of body types.
[0042] Unlike traditional chairs or passive backrests, this system offers active guidance, helping users build postural awareness and muscle memory over time. By providing gentle, timely corrections without distraction, the invention fosters a balanced state of alertness and relaxation, essential for effective meditative practice.
[0043] Furthermore, the meditation chair is designed for versatile operation in both indoor and remote environments, incorporating a built-in rechargeable battery for portable use and an AC power input (compatible with 230V mains supply) for uninterrupted operation when connected to a standard wall outlet.
[0044] Figure 1: Front view of meditation chair: This image shows a 3D side view of the "Sensor-Based Postural Correction Meditation Chair" as described in the patent. The chair is displayed in its upright, open position, featuring a teal-colored cushioned seat and a maroon vertical backrest designed for ergonomic support during meditation. The base serves as a stable platform for seated postures like Sukhasana, while the backrest houses the internal components—including a proximity sensor and an adjustable shaft mechanism—though they are not externally visible in this view. These internal systems are designed to detect slouching and gently correct the user’s posture using a soft silicon-tipped actuator. The overall design reflects a minimalist yet functional approach, ensuring both physical comfort and active postural correction without interrupting the meditative state.

The visible color scheme includes a maroon/red exterior casing and teal cushioning layers, consistent with the chair's functional design in open form. This configuration highlights the chair’s ‘portability and space-saving utility, making it ideal for storage or transport. Internally, the folded structure still houses the core components—such as the proximity sensor, shaft mechanism with silicon pad, and control unit—which remain protected and intact in this form. The image demonstrates the chair’s ability to transition smoothly between active use and compact storage, a critical feature for users practicing meditation in limited or mobile environments.
[0046] Figure 3. Side view of chair with sensor placement: This image shows the ‘right-side view’ of the "Sensor-Based Postural Correction Meditation Chair" in its open and operational form. It provides a clear visualization of the chair's internal components, which are embedded within the backrest. The teal seat and maroon backrest structure remain consistent with the overall ergonomic design. Notably, the ‘proximity sensor (purple)’, ‘silicon pad-tipped shaft (green)’, and ‘control unit (blue)’ are partially visible from this angle, indicating how they are aligned along the user’s lower back. This side view highlights how the sensor detects deviations from upright posture, triggering the shaft—through signals from the control unit—to gently nudge the user back into alignment. The image effectively demonstrates the functional layering and side-to-side alignment of the embedded components, confirming the precision and compactness of the posture correction mechanism.

Front view of chair with sensor placement: This image is a labeled 3D diagram of the Sensor-Based Postural Correction Meditation Chair, specifically highlighting the internal components that enable its intelligent posture correction functionality. The chair is shown in an open, upright configuration with annotations pointing to three key embedded features: a Proximity Sensor (in purple), a Silicon Pad (in green), and a Controlling Unit (in blue). The proximity sensor is positioned within the backrest and is responsible for detecting the user's spinal alignment by measuring the distance between the lower back and the chair. When slouching is detected beyond a set threshold, the sensor signals the controlling unit, which then activates the shaft mechanism behind the backrest. This mechanism pushes forward a soft silicon pad, gently touching the user’s lower back to encourage correction of posture. The controlling unit processes input from the sensor and coordinates the actuator's motion, ensuring smooth, non-intrusive correction. This diagram visually demonstrates how the system works in tandem to maintain upright posture and train the user’s spinal awareness during meditation.
