Specification

Description:FIELD OF THE INVENTION

[0001] The present invention relates to an over-head shading device that is securely worn on the user's back and head in view of ensuring maximum comfort and protection from external environmental factors, while making automatic adjustments based on the user's physical dimensions and movements.

BACKGROUND OF THE INVENTION

[0002] Overhead shading for humans is essential for both health and comfort, especially in regions with intense sun exposure. Prolonged exposure to direct sunlight lead to various health risks, including skin damage, dehydration, and heat-related illnesses like heatstroke. Overhead shading, such as canopies, umbrellas, or shade trees, helps mitigate these risks by providing a protective barrier against harmful UV radiation. This shading also creates a cooler microenvironment, which is crucial in urban areas where the urban heat island effect raises temperatures, exacerbating discomfort and health concerns. Additionally, shaded areas encourage outdoor activity by making public spaces, parks, and streets more inviting during hot weather. From an environmental perspective, shading reduce the need for air conditioning, lowering energy consumption and carbon footprints. Furthermore, this enhances social interaction and relaxation by offering people a comfortable space to gather without the risk of overexposure to the sun. Overhead shading is a simple yet effective solution to safeguard public health, promote outdoor engagement, and help combat the effects of climate change.

[0003] Traditional methods of covering and shading the head have included various forms of headgear such as hats, turbans, scarves, and cloaks, which have been used across cultures for protection from the sun and environmental elements. These items often offer direct physical protection from sun exposure, keeping the head cool and shielding the face and neck from harmful UV rays. For example, wide-brimmed hats provide shade, while turbans and scarves offer both warmth and shade. In some cultures, large umbrellas or palm fronds have been used to create temporary overhead shade. However, these methods come with several drawbacks. Headgear like hats and turbans are uncomfortable in extreme heat, potentially leading to sweating, restricted airflow, and overheating. Scarves do not provide adequate coverage for the neck or shoulders, leaving those areas exposed. Additionally, traditional methods are cumbersome and less practical for continuous or long-term outdoor exposure. While umbrellas are effective, they are often not portable in windy conditions or may require hands to hold them, limiting freedom of movement.

[0004] US3709238A discloses about an invention that has a retractable umbrella having a central tubular storage handle into which a top cover and multiple stays slide or telescope when retracted for storage, and from which the cover and stays are propelled axially to open in an outwardly expanding direction to provide a top cover adapted to be carried by means of the central tubular handle.

[0005] US3844301A discloses about an invention that has a collapsible umbrella having a plastic frame forming an elongated cage for compacting and folding the cover canopy therein. The main frame is dual U shaped and includes an integral handle in which a control member is manually reciprocated for opening the canopy and retracting same into the main frame. The frame includes a closure at both ends for protecting the folded canopy. The fabric or plastic canopy is supported by a plurality of flexible ribs which are sprung into a conventional sheet plastic or fabric canopy or a transparent plastic for a bubble type canopy.

[0006] Conventionally, many methods are available for protecting shade. However, the cited invention relies on mechanisms that require manual effort for operation, which is cumbersome and less user-friendly, especially when the device is being used in outdoor conditions. The retraction and expansion of the covers are often dependent on mechanical parts that are prone to wear and tear over time, leading to reduced reliability. The collapsible nature of the designs results in inadequate coverage or protection, as the user has limited control over the shade provided.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that is capable of offering greater ease of use, enhanced durability, and adaptability to various environmental conditions. The device should be capable of automatically adjusting to the user's needs without requiring manual intervention, providing reliable, consistent shade or shelter. The developed device must be able to respond to changes in weather conditions in real-time n view of ensuring that the user remains protected from the elements without the need for complex setups or constant adjustments.

OBJECTS OF THE INVENTION

[0008] The principal object of the present invention is to overcome the disadvantages of the prior art.

[0009] An object of the present invention is to develop a device that is capable of securely positioned on the user's back and head in view of ensuring optimal comfort and protection from environmental elements.

[0010] Another object of the present invention is to develop a device that is capable of enabling the user to select and customize the type of canopy material for shading based on weather conditions, thus enhancing user experience in various climates.

[0011] Another object of the present invention is to develop a device that is capable of detecting the user's physical dimensions and environmental factors for ensuring precise and automatic adjustments to the device, regardless of the user's posture or movement.

[0012] Another object of the present invention is to develop a device that is capable of carrying out light intensity regulation in order to enhance the user's comfort in extreme weather conditions like heat or low light.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting. While the invention is susceptible to various modifications and alternative constructions, it should be understood, that there is no intention to limit the invention to the specific form disclosed, but, on the contrary, the invention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention as defined in the claims.

[0020] In any embodiment described herein, the open-ended terms "comprising," "comprises," and the like (which are synonymous with "including," "having" and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0021] As used herein, the singular forms "a," "an," and "the" designate both the singular and the plural, unless expressly stated to designate the singular only.

[0022] The present invention relates to an over-head shading device that detects and responds to changes in environmental factors, such as light intensity, temperature, and humidity, and adjusts the height, position and provide shading automatically to optimize user comfort and protection in varying conditions, thereby providing a more comfortable and hassle-free experience.

[0023] Referring to Figure 1, an isometric view of an over-head shading device, comprising a body 101 developed to be positioned at back portion of a user via a pair of straps 102, a horizontal plate 103 is installed with the body 101via a threaded shaft 104 such that multiple spools 105 wrapped with different type of sheets 106, a motorized roller 107 configured with each of the straps 102, an artificial intelligence-based imaging unit 108 mounted on the plate 103, a telescopically operated rod 109 installed with each corner of the plate 103 and each equipped with a pair of motorized clamp 110, a motorized slider 111 configured with each of the clamp 110, a motorized hinge 112 configured between each of the rod 109 and corner of the rod 109, plurality of LED (Light Emitting Diode) lights 113 arranged on the plate 103, a mist atomizer 114 configured with the plate 103 and a solar panel 115 is arranged on the plate 103.

[0024] The device disclosed herein includes a body 101 that is developed to be worn by the user which is securely positioned on the back portion of the user using a pair of straps 102. These straps 102 are developed to be placed over the user's shoulders, similar to the straps 102 of a backpack to distribute the weight and ensure comfort during wear. The body 101 structure acts as the central support developed to hold and stabilize the device in view of ensuring it remains firmly in place while the user is moving or engaging in various activities. The straps 102 are adjustable to accommodate different body 101 sizes and shapes for ensuring that the device is customized to fit various users.

[0025] A horizontal plate 103 is attached to the body 101 via a threaded shaft 104 for allowing the plate 103 to be positioned at a fixed angle relative to the user. The use of a threaded shaft 104 allows for precise control of the plate's positioning and enables adjustments to be made such as raising or lowering the plate 103, depending on the user's preference or environmental conditions. The plate 103 is crucial as this acts as the base where multiple spools 105 are installed, each wrapped with a different type of sheet 106 developed for varying shading needs. The sheets 106 on the spools 105 are typically made of materials that include but limited to fabric, polymers, or reflective materials, and serve the purpose of protecting the user from environmental elements like sun, rain, and wind.

[0026] Each spool is wrapped with a specific type of shading material, offering different benefits depending on the environmental conditions or the user's preference. For example, one spool contains an opaque sheet 106 developed to block UV rays and provide full shade which is ideal for hot and sunny days. Another spool contains a translucent sheet 106 that diffuses light for making it suitable for cloudy days or evening use, allowing for soft, ambient lighting. Also, one spool is fabricated with reflective sheet 106 which is useful for colder weather, reflecting heat back onto the user to help maintain warmth. The spools 105 are arranged on either side of the horizontal plate 103, allowing for quick and easy access to the desired sheet 106.

[0027] The horizontal plate 103 is developed with the threaded shaft 104 running through its center, to which the spools 105 are attached. This allows the sheets 106 to be rolled and unrolled as needed, with the user selecting the sheet 106 of choice through a user interface linked wirelessly to the device's inbuilt microcontroller. The threaded shaft 104 not only helps to mount the plate 103 but also controls the height and position of the plate 103, ensuring that it remains at the optimal level for providing shade to the user. The movement of the threaded shaft 104 is motorized, controlled by the microcontroller, allowing the device to adjust the height of the plate 103 automatically based on inputs from sensors that detect the user's height or posture.

[0028] The user interface inbuilt in a computing unit together facilitate the device's adaptability and user control. The user interface enables the user to interact with the device and input commands related to the type of shading sheet 106 they want to use, as well as to adjust the device's settings for comfort and usability. This user interface is inbuilt in the computing unit, which is a centralized processing unit that interprets the user's commands and sends appropriate signals to various components of the shading device to perform the desired actions.

[0029] The user interface includes but not limited to a touch screen, buttons, a mobile app, or a voice-controlled, depending on the intended user experience. The interface to allow the user to select the type of sheet 106 they want to deploy for shading whether it is opaque sheet 106 for UV protection, translucent sheet 106 for diffused light, or the reflective sheet 106 for heat retention. The user makes these selections easily through intuitive controls, and the commands are transmitted wirelessly to the microcontroller.

[0030] The microcontroller is wirelessly linked to the computing unit, allowing communication between the two through different communication modules, such as Wi-Fi (Wireless Fidelity), Bluetooth, or GSM (Global System for Mobile Communication) modules. These communication modules facilitate the wireless transmission of input data from the user interface to the microcontroller, which then processes the user's commands. The choice of communication module depends on the range, power consumption, and connectivity requirements of the device. For example, Wi-Fi is preferred when the device is used in environments with an existing internet connection, allowing the user to control the device remotely through a smartphone or laptop. Bluetooth is used for close-range communication, such as when the user is in direct proximity to the device. GSM modules, on the other hand, is used for remote control through text messaging or mobile apps, especially in outdoor settings where internet access is unreliable but mobile network coverage exists.

[0031] Once the microcontroller receives the user's input, it processes this information and sends out commands to different components to adjust the device's settings accordingly. The microcontroller aids in device's adaptability to the user's body size, posture, and movement. To ensure that the device is worn comfortably and securely, multiple laser sensors are integrated into the straps 102 of the device. These sensors are positioned along the straps 102 and detect the dimensions of the user's shoulders, including the width and circumference of the chest and upper body. The laser sensors function by emitting beams of light, which are reflected back after hitting the surface of the user's shoulders. By measuring the time taken for the light to return, the sensors accurately calculate the user's shoulder dimensions in real-time.

[0032] Based on this data, the microcontroller uses the measurements to determine whether the straps 102 are properly secured around the user's shoulders. If the straps 102 are too loose or too tight, the microcontroller activates motorized roller 107 attached to each strap to adjust their tightness. The roller 107 rotate in response to signals from the microcontroller, which causes the straps 102 to either tighten or loosen around the user's shoulders in view of ensuring a secure and comfortable fit. This automatic adjustment removes the need for manual tightening or loosening, providing a more efficient and ergonomic solution for users, especially in dynamic or outdoor environments where manual adjustments is cumbersome.

[0033] The motorized roller 107are configured with the straps 102 in such a way that they allow for precise control over the tension applied. The rotation of these roller 107 is controlled by the microcontroller, which commands the motorized roller 107 to tighten or release the straps 102 as needed. This ensures that the body 101 remains securely attached to the user's back, without causing discomfort or restricting movement.

[0034] An artificial intelligence (AI)-based imaging unit 108 is mounted on the plate 103 itself in view of ensuring that it is in an optimal position to capture real-time images of the user, allowing for continuous monitoring of their height and head positioning. An onboard processor paired with the imaging unit 108 is responsible for processing the data captured by the imaging unit 108, analyzing the user's physical dimensions, and providing the necessary inputs to the microcontroller to adjust the position of the plate 103.

[0035] The artificial intelligence-based imaging unit 108 typically includes camera that is capable of capturing images or depth data of the user's body. This imaging unit 108 is developed to detect and process multiple images of the user's upper body, specifically focusing on the area around the head. The AI protocols embedded in the processor intelligently process these images to determine the height of the user with a high degree of accuracy. The AI unit utilizes machine learning and computer vision techniques, which are trained to recognize and identify key body features such as the head, shoulders, and torso in view of allowing the imaging unit 108 to estimate the user's height even in dynamic or varying environmental conditions.

[0036] Once the AI imaging unit 108 has processed the images and determined the height of the user, this information is sent to the microcontroller which uses it to make real-time adjustments to the position. The microcontroller commands a bi-directional DC motor which is coupled to the shaft 104 that connects to the horizontal plate 103. This motor rotates the shaft 104 either in a clockwise or anti-clockwise direction, depending on the required adjustment. The rotation of the shaft 104 moves the plate 103 either upward or downward in view of ensuring that the plate 103 maintains an optimum height from the user's head, regardless of their posture, movements, or changes in body position.

[0037] The device maintains the optimal distance between the shading plate 103 and the user's head at all times. This is crucial for providing consistent shading and comfort, as this prevents the plate 103 from being too high, which cause the user to be exposed to the sun or rain, or too low, which result in the plate 103 obstructing the user's view or movements. The AI-based imaging unit 108 ensures that these adjustments are made dynamically in view of providing the user with a customized experience based on their unique body dimensions and the specific environmental conditions.

[0038] For example, if the user is tall, the AI imaging unit 108 detect the height and adjust the plate 103 to a higher position to ensure that the shading sheet 106 adequately covers the user's head. Similarly, if the user is shorter or sitting down, the shaft 104 lower the plate 103 to ensure that the shade is still provided without causing discomfort or obstruction. This dynamic adjustment process ensures that the user is always protected from the sun, rain, or other environmental factors without the need for manual intervention or constant readjustment.

[0039] The AI imaging unit 108 also contributes to adapt to different users, environments, and activities. For example, if the device detects that the user is moving in and out of sunlight such as walking between shaded and sunny areas, this automatically adjust the height of the plate 103 to optimize shading in real-time. In more extreme weather conditions, such as a sudden rainstorm, the device adjust the plate's height or even switch to a different type of shading material to provide better protection.

[0040] To facilitate seamless operation, the bi-directional DC motor and shaft 104 work together to provide smooth, responsive, and precise movements. The bi-directional motor allows for easy upward and downward adjustments, and the shaft's mechanical design ensures that the plate 103 moves uniformly and without jerky motions. The motor's control is handled by the microcontroller, which receives input from the imaging unit 108 and calculates the necessary movements in view of ensuring that the plate's position is constantly optimized for user comfort.

[0041] A telescopically operated rod 109 is installed at each corner of the horizontal plate 103 for providing dynamic adjustability and versatility to the device, allowing to adapt to different environmental conditions and user needs. The telescopic rod 109 are developed to extend or retract depending on the required coverage, and they are powered by a pneumatic unit, which includes an air compressor, air cylinders, air valves, and pistons working together in a synchronized manner. These rod 109 expand and contract in response to changes in the weather, user preferences, or the positioning of the shading plate 103 in view of ensuring that the device remains flexible and responsive under various circumstances.

[0042] At the ends of these telescopic rod 109, there are motorized clamps 110 that secure and adjust the shading sheet 106 used for providing cover. These clamps 110 are positioned to grip the free ends of the shading material that are wrapped around one of the multiple spools 105 situated on either side of the plate 103. The microcontroller, determines which roller 107 is associated with the user-specified type of sheet 106 based on the input commands received from the user. The user is able to select from different types of sheets 106, including opaque, translucent, or reflective sheets 106, depending on the specific weather conditions or the user's comfort preferences. Once the type of sheet 106 is chosen, the microcontroller actuates the motorized clamps 110 to grip the free ends of the selected sheet 106 and position it appropriately for shading.

[0043] For example, in hot and sunny weather, when high levels of ultraviolet (UV) radiation are present, the device smartly engage the opaque sheet 106. The opaque sheet 106, which is developed to block out harmful UV rays, provides robust protection against skin damage or sunburn, keeping the user cool and safe under intense sunlight. This helps to automate the shading process, reducing the need for user intervention while ensuring optimal comfort and protection.

[0044] The opaque sheet 106 is particularly beneficial in summer weather, as it blocks UV rays effectively, preventing skin burns, overheating, and dehydration. The device's ability to automatically deploy the appropriate sheet 106 based on weather conditions ensures that the user always has the right level of protection without needing to manually adjust the device. In winter or autumn weather conditions, when the temperature drops and the sunlight is less intense, the user prefer the translucent sheet 106. The translucent sheet 106 allows a softer diffusion of light, creating a warm, ambient atmosphere while still protecting the user from rain or snow. This sheet 106 type provides a gentler shading effect compared to the opaque sheet 106, allowing some light to pass through while offering enough protection against precipitation and cold winds. The soft diffusion of light helps maintain visibility and creates a cozy, inviting environment for the user, making it ideal for cooler, less sunny days when bright sunlight is not as much of a concern but protection from rain or snow is still required.

[0045] For chilly days, or when the user needs extra warmth, the reflective sheet 106 is selected. This type of sheet 106 is developed to reflect heat back towards the user, providing warmth during colder conditions. The reflective properties of the sheet 106 work by capturing and reflecting radiant heat, such as the heat generated by the user's body or from external sources like the sun or artificial heaters. This is particularly beneficial in winter or early spring when the temperature is low but there is still some exposure to sunlight. The reflective sheet 106 helps to trap heat under the canopy, ensuring that the user stays warm even in low temperatures. The reflective sheet 106 enhances the visibility of the user in low-light situations, such as dusk or during foggy conditions, making it easier for others to see the user and improving safety in outdoor environments.

[0046] The motorized clamps 110 work in conjunction with the telescopic rod 109 to adjust the position of the shading sheet 106 and ensure it is spread evenly across the user's head and shoulders. Once the microcontroller determines which type of sheet 106 is selected, this activates the clamps 110 to grip the free ends of the sheet 106 from the appropriate spool. The clamps 110 then move towards the ends of the telescoping rod 109, pulling the sheet 106 taut and positioning it overhead to create a protective canopy. This dynamic process ensures that the user receives continuous shading and comfort regardless of weather changes.

[0047] To accommodate different user sizes, the telescopically operated rod 109 adjust the height and angle of the shading sheet 106, providing a customized solution for different body types and activities. This allows for quick, efficient adjustments, whether the user is walking, standing, or sitting, and ensures that the device remains responsive to environmental changes and user preferences.

[0048] Each clamp 110, which is installed at the end of the telescopic rod 109 is paired with a motorized slider 111 that allows the clamps 110 to move along the rod 109. This is controlled by the microcontroller, which processes input commands from the user and adjusts the position of the sheet 106 as needed. When the user selects a particular type of sheet 106 through the user interface, the microcontroller processes this input and determines which spool is associated with the desired sheet 106. The clamps 110 at the ends of the telescopic rod 109, which are developed to grip the free-ends of the chosen sheet 106, are actuated to secure the material. Once the free ends of the sheet 106 are grasped, the motorized slider 111 translate the clamps 110 towards the ends of the telescopic rod 109, thereby pulling the shading material taut and positioning it directly above the user's head.

[0049] After the user selects the type of sheet 106 through the user interface, the microcontroller activates the motorized clamps 110 to grip the free ends of the sheet 106. These clamps 110 are responsible for holding the sheet 106 tightly, ensuring it does not slip or become loose. Once the sheet 106 is gripped securely, the motorized slider 111 moves the clamps 110 along the telescopic rods 109. The microcontroller directs the slider 111 to move in a linear direction, either extending or retracting it along the rods 109, depending on the user's position and the height requirements for optimal shading. The translation ensures that the sheet 106 covers the user's head effectively. As the slider 111 move, they extend the sheet 106 over the user's head, ensuring that it stays taut and evenly spread. This adjust the sheet's position based on the user's movements, so the shading material maintains consistent coverage even if the user is walking or changing posture.

[0050] A motorized hinge 112 is positioned between each rod 109 and the corner of the rods 109 to provide dynamic adjustability to the device. When the imaging unit 108, integrated with the microcontroller, detects that the user is carrying luggage either in their hands or on their back, the device responds by adjusting the position of the plate. The microcontroller processes the image data and triggers the rods 109 to extend, which are also equipped with the motorized hinge 112. This hinge 112 allows the rods to tilt, ensuring that the device not just protect the user's head, but also adapts to shield the luggage from sun or rain. The synchronization between the extension of the rods and the actuation of the hinge 112 allows the canopy to adjust its angle, forming a protective covering over the user's belongings. By tilting the rods at an optimal angle, the device creates a more effective and personalized shading solution that ensures both the user and their luggage are covered regardless of changes in posture or carrying objects.

[0051] An LDR (Light Dependent Resistor) is placed on the plate 103 that continuously monitors the ambient light conditions in the immediate surroundings of the user. The LDR works simply when the intensity of light increases, the resistance of the LDR decreases, allowing more current to flow through it. Conversely, when the light intensity decreases, the resistance of the LDR increases, limiting the current flow.

[0052] This change in resistance is detected by the microcontroller that interpret the resistance values from the LDR and use them to determine the surrounding light conditions. Specifically, the microcontroller is pr-fed to recognize when the light intensity falls below a predefined threshold, indicating a reduction in natural light, such as during cloudy weather, dusk, or when the user is moving under a shaded area. When the LDR detects that the surrounding light intensity has dropped below the threshold level, this information is sent to the microcontroller. The microcontroller then processes this input and takes appropriate action. The microcontroller then activates LED lights 113 embedded into the plate 103 to illuminate the surrounding area. The activation of the LED lights 113 helps to compensate for the lack of natural light, providing ambient lighting that ensures the user remains comfortable and able to see in low-light conditions.

[0053] The LED lights 113 are arranged around the plate 103 or on the edges to illuminate a broad area directly above the user's head. These LED lights 113 are energy-efficient, durable and capable of producing a variety of lighting effects, from soft, diffused light to brighter focused illumination, depending on the requirements. The microcontroller adjusts the brightness and the number of LEDs that are turned on based on the level of light deficiency detected by the LDR.

[0054] A humidity sensor is arranged on the plate 103 that measures the moisture content in the air, indicating the level of relative humidity in the surrounding environment. Relative humidity refers to the percentage of water vapor present in the air compared to the maximum amount of water vapor the air hold at a given temperature. When the relative humidity exceeds a certain threshold, the air feels muggy and the body's natural cooling such as sweating become less effective which leads to discomfort.

[0055] The humidity sensor detects the real-time humidity levels and transmits this data to the microcontroller. If the sensor detects that the humidity has risen above a pre-fed threshold level, indicating that the air has become too humid for optimal comfort, the microcontroller initiates action. The threshold for activation is adjusted based on user preferences or set according to environmental standards, such as a certain percentage of humidity is 70% relative humidity or higher. The microcontroller continuously monitors the sensor's output, ensuring that the device reacts promptly to any increase in humidity.

[0056] When the humidity sensor reports that the ambient humidity has exceeded the threshold level, the microcontroller sends a signal to activate a mist atomizer 114. The atomizer 114is developed to convert water into a fine mist using pressurized mechanism, which is then dispersed into the air around the user. This mist, which consists of tiny water droplets, serves to cool the surrounding air through the process of evaporative cooling. The mist atomizer 114 is placed on the plate 103 for ensuring that it produces a fine mist that falls directly onto the user's immediate vicinity, including the head and shoulders, where the body loses heat most effectively. Depending on the device, the atomizer 114 releases the mist intermittently or continuously n view of depending on the level of humidity and the specific settings chosen by the user.

[0057] The cooling effect of the mist atomizer 114 is achieved through the process of evaporative cooling, which occurs when the fine mist evaporates into the air. As the tiny water droplets are released into the air, they absorb heat energy from the surrounding environment, causing the water to change from a liquid to a gas. This phase change requires energy, and this energy is drawn from the surrounding air, leading to a drop in the temperature of the air around the user. The evaporation of water molecules cools the immediate environment in view of providing a refreshing and cooling effect on the user's skin. This evaporative cooling is particularly effective in humid climates, as the mist helps to reduce the oppressive feeling caused by excessive moisture in the air.

[0058] A battery (not shown in figure) is associated with the device to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrodes named as a cathode and an anode. The battery uses a chemical reaction of oxidation/reduction to do work on charge and produce a voltage between their anode and cathode and thus produces electrical energy that is used to do work in the device.

[0059] To ensure sustainable operation, especially during outdoor use, a solar panel 115 is mounted on the plate 103 of the device, where this harvests energy from solar radiation. This solar energy is then stored in the battery, allowing the device to operate autonomously without relying solely on external power sources. The combination of the battery and solar panel 115 ensures that the device remains operational in outdoor environments, even during extended periods without access to traditional power outlets, making it energy-efficient and eco-friendly.

[0060] The present invention works best in the following manner, where the user secures the body 101 to their back using the pair of straps 102 as disclosed in the proposed invention. The body 101 is adjusted for complete fit via motorized roller 107 based on the shoulder dimensions detected by laser sensors. The user then selects the desired type of shading sheet 106 through the wireless interface linked to the computing unit, which communicates the input to the microcontroller. This triggers the AI-based imaging unit 108 detects the user's height and sends the data to the microcontroller, which adjusts the height of the horizontal plate 103 using the bi-directional DC motor to maintain optimal positioning above the user's head. The telescopically operated rods 109 at each corner of the plate 103 extends or retracts the rods 109 as needed. The microcontroller then determines the appropriate sheet 106 from one of the spools 105 and activates motorized clamps 110 to grip the free ends of the sheet 106. These clamps 110 with the help of motorized slider 111 translate the sheet 106 towards the user's head, providing shade. Herein, if the imaging unit 108 detects any luggage being carried by the user, the microcontroller adjusts the rods 109 and hinge 112 to form the canopy that prevents sun or rain from affecting the luggage.
