BACKGROUND OF THE INVENTION

[0002] Electrical power delivery assistance for visually impaired users is essential for ensuring the safety and independence in managing electrical systems. Since visually impaired individuals struggle to identify power sources, switches, or outlets, specialized support helps them navigate and use electrical systems more confidently. This assistance reduces the risk of accidents, like electrical burns or fires, and empowers them to independently control household or work-related appliances. Ultimately, integrating accessible power delivery solutions enhances the overall quality of life and fosters inclusivity, allowing visually impaired individuals to engage more fully with their environment.

[0003] Traditional methods of electrical power delivery assistance for visually impaired users include tactile markers on switches and outlets, Braille labels, and raised symbols to indicate control points. Auditory cues, such as talking thermostats or alarm systems, also provide guidance. Additionally, specialized tools like vibrating alerts assist the users in identifying the different electrical components. These methods, while effective, often rely on basic, physical interaction and manual assistance to ensure safe usage. The drawback of traditional methods is that they often require physical interaction, which is limiting or cumbersome for visually impaired users. Tactile markers and Braille labels are not universally understood or easy to locate, and manual control systems are inefficient.

According to the safety plug and the socket, inclined faces are used for guiding, two sides of the plug are symmetrical inclined faces, so that the self-centering effect can be achieved, alignment and positioning can be conducted quickly and accurately. According to the safety plug and the socket, a plurality of functions such as fall prevention and electric shock prevention of the plug are integrated, so that the safety plug and the socket are more convenient to operate than existing products, the cost is low, the comparison effect is obvious, and the safety plug and the socket are applicable to blind persons, amblyopia patients, the old, children and retarded persons and are wide in application range.

[0006] Conventionally, many systems have been developed for providing electrical power delivery assistance to visually impaired users, but the existing system often requires manual assistance to ensure safe usage and these systems lack in detecting the presence and direction of the power connection unit in the vicinity of the nearest receiving point and alerting the visually impaired user regarding the positioning of the power connection unit in alignment with the receiving point. In addition, the tactile markers and Braille labels are not universally understood.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a system that requires to be capable of detecting presence and direction of the power connection unit in the vicinity of the nearest receiving point and alerting the visually impaired user regarding the positioning of the power connection unit in alignment with the receiving point. Additionally, the developed system also needs to be capable of detecting burnt receiving point and the presence of moisture near the receiving point and alerting the visually impaired user for the same to prevent any potential electrical accidents.

DETAILED DESCRIPTION OF THE INVENTION

[0018] 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.

[0019] 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.

[0020] 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.

[0021] The present invention relates to an electrical power delivery system for visually impaired users that is capable of detecting burnt receiving point and the presence of moisture near the receiving point and alerting the visually impaired user for the same to prevent any potential electrical accidents.

[0022] Referring to Figure 1, an isometric view of an electrical power delivery system for visually impaired users is illustrated, comprising a rotatable electrical socket 101 housed within an enclosure 102 by means of a rotary joint 103, a plug-in adapter 104, an ultrasonic transducer 105 installed with the socket 101 and an ultrasonic receiver 106 mounted with the adapter 104, a braille output unit 107, a haptic feedback unit 108, an audio buzzer 109, a grid of pneumatic pins 110 arranged over a surface of the adapter 104, an articulated extendable arm 111 mounted over the adapter 104, an electrically insulated tip 112 formed at an end of the arm 111, a camera 113 embedded with the enclosure 102, a housing 114 integrated at a front portion of the enclosure 102, a claw 115 installed with an inner surface of the housing 114 by means of a dual axis gantry 116.

[0023] The system disclosed herein employs a rotatable electrical socket 101. This rotatable electrical socket 101 receives power from a power source that is housed within an enclosure 102 by means of a rotary joint 103. The rotary joint 103 is a circular sliding unit. The circular sliding unit within the rotary joint 103 of the rotatable electrical sockets 101 operates by facilitating electrical power transfer between the stationary power source and the rotating socket 101 through the sliding assembly. The circular sliding unit consists of a circular conductive ring that is attached to the rotating part of the socket 101 and is designed to make contact with stationary conductive sliders mounted within the enclosure 102, which is connected to the power source. As the socket 101 rotates, the circular conductive ring slides smoothly against the sliders, maintaining a stable electrical connection without interruption. The entire assembly is preferably encased in an insulating shield to prevent electrical hazards and protect the internal components from environmental factors.

[0024] For activating the system, the user needs to press a push button which is arranged on the socket 101 which in turn activates all the related components for performing the desired task. After pressing the button, a closed electrical circuit is formed and current starts to flow that powers an inbuilt control unit to allow all the linked components to perform their respective task upon actuation.

[0025] A mesh network module interconnecting a plurality of the sockets. The mesh network module is based on a communication unit installed with the sockets, operating over a communication protocol selected from Bluetooth, Wi-Fi and a combination thereof. The mesh network module functions as the backbone of communication between multiple sockets, ensuring they interact with each other over a decentralized network. Each socket of the multiple sockets is equipped with a communication unit, which operates over communication protocols such as Bluetooth, Wi-Fi, or a combination of both. The Wi-Fi module contains transmitters and receivers that use radio frequency signals to transmit data wirelessly to the control unit. The wireless module typically includes components such as antennas, amplifiers, and processors to facilitate communication and further connected to networks such as Wi-Fi, Bluetooth, or cellular networks, allowing systems to exchange information over short or long distances.

[0026] The mesh network module ensures that even if a socket is out of range of another, the message is relayed through intermediate sockets, creating a self-healing and resilient network. The communication protocols used, whether Bluetooth for shorter ranges or Wi-Fi for longer distances, allow the system to dynamically adapt based on network conditions and power requirements. The module enables functions like remote control, coordination between sockets for synchronized actions, and real-time data sharing, such as power consumption or operational status. The plurality of sockets are individual nodes in the mesh network, each containing a built-in communication unit that enables it to connect and exchange information with other sockets. Each socket is capable of operating independently, but as part of the mesh network, it relays messages, shares data, or executes synchronized actions in response to commands from the control unit.

[0027] A plug-in adapter 104 to couple with the socket 101 to supply power to an electrical unit. The plug-in adapter 104 is used to couple with the rotatable socket 101 to provide power to the electrical unit. Internally, the adapter 104 contains a set of conductive prongs that align with the electrical contacts inside the socket 101, allowing for a secure connection to the power source. When the adapter 104 is inserted into the socket 101, these prongs make contact with the socket’s terminals, establishing a flow of electricity from the socket 101 to the electrical unit. The adapter 104 is typically insulated to prevent any accidental contact with live electrical components and to ensure safety during use.

[0028] A proximity detection module is installed with the socket 101 and the adapter 104 that is activated to detect the adapter’s presence and direction in the vicinity of the nearest socket 101 in accordance with the mesh network. The proximity detection module comprises an ultrasonic transducer 105 that is installed with the socket 101 and an ultrasonic receiver 106 that is mounted with the adapter 104. The ultrasonic transducer 105 emits high-frequency sound waves, typically in the ultrasonic range (above 20 kHz), which are not audible to humans. When the adapter 104 comes within the vicinity of the socket 101, the ultrasonic transducer 105 sends out a pulse of these sound waves in all directions. The transducer 105 functions as both a transmitter and receiver, it transmits the ultrasonic waves and then listens for the reflection of those waves after they hit the ultrasonic receiver 106 mounted on the adapter 104. The time taken for the sound waves to return is measured. This allows to determine the distance between the socket 101 and the adapter 104. This data is then used by the proximity detection module to detect the presence and approximate location of the adapter 104 relative to the socket 101. Additionally, the transducer 105 identifies the direction in which the adapter 104 is positioned, enabling the mesh network to understand the relative orientation of the adapter 104 and socket 101.

[0029] The ultrasonic receiver 106 works by detecting the ultrasonic sound waves emitted by the ultrasonic transducer 105 in the socket 101. Once the transducer 105 sends out a pulse, the receiver 106 listens for the return of these waves. By measuring the time of flight (the time taken for the ultrasonic waves to travel from the transducer 105 to the receiver 106 and back), the receiver 106 calculates the distance between the socket 101 and the adapter 104. If the receiver 106 detects the reflected signal, it signals the proximity detection module, which confirms the presence of the adapter 104 and calculates the position relative to the socket 101. The receiver 106 also helps to detect the direction of the adapter 104, allowing the system to know if the adapter 104 is facing toward the socket 101 or positioned in a particular orientation.

[0030] A detection module is configured with the control unit that receives parameters of the ultrasonic waves transmitted and received by the proximity detection module to determine the distance and the direction of the socket 101 with respect to the adapter 104. The detection module works by processing the ultrasonic wave data received from the proximity detection module. The detection module relies on the principle of time-of-flight measurement to determine the distance and direction of the socket 101 relative to the adapter 104. When the proximity detection module emits ultrasonic waves, the detection module receives information on both the transmitted and reflected waves. The time taken for the ultrasonic waves to travel from the proximity module to the socket 101 and then back to the module is measured. This time of flight is directly proportional to the distance between the socket 101 and the adapter 104. The detection module calculates the distance, accounting for the round-trip journey of the sound waves. Additionally, the detection module uses the angle of the reflected waves to assess the direction of the socket 101. By analyzing the pattern of the received signal, the detection module determines which direction the socket 101 is in relative to the adapter 104.

[0031] An alert unit is installed with the adapter 104 that generates an alert for the user. Upon detection of the socket 101 being in close vicinity of the adapter 104 as determined by the proximity detection module, the alert unit guides the user to position the adapter 104 in alignment with the socket 101. The close proximity distance is pre-defined within the control unit that is associated with the system. The alert unit comprises one or more of a braille output unit 107, a haptic feedback unit 108 and an audio buzzer 109. The braille output unit 107 comprises a grid of pneumatic pins 110 that is arranged over a surface of the adapter 104 to indicate the direction of the socket 101 with respect to the adapter 104. The grid of pneumatic pins 110 is selectively extended and retracted to form braille characters.

[0032] The braille output unit 107 works by guiding the user to align the adapter 104 with the socket 101. The braille output unit 107 consists of a grid of pneumatic pins 110 arranged on the surface of the adapter 104. The pneumatic pins 110 extend and retract by using nested sections that slide within each other, driven by a pneumatic unit. The pneumatic unit for extension and retraction operates using compressed air to drive a piston inside a cylinder. When air is supplied to one side of the piston, it creates pressure that pushes the piston rod outward, causing extension. To retract, air is supplied to the opposite side while the initial chamber is vented, pulling the piston rod back.

[0033] The pneumatic pins 110 are selectively extended and retracted based on the proximity of the socket 101, which is detected by the proximity detection module. When the adapter 104 detects that the socket 101 is in close vicinity, the proximity detection module sends the distance data to the control unit. If the adapter 104 is not properly aligned with the socket 101, the control unit activates the pneumatic pins 110 to extend in specific patterns, forming braille characters on the surface of the adapter 104. These raised pins 110 provide feedback to the user, allowing them to feel the direction in which the socket 101 is located relative to the adapter 104. This feedback from the pneumatic pins 110 assists the user to align the adapter 104 precisely with the socket 101, providing an intuitive and accessible way to ensure proper alignment.

[0034] The haptic feedback unit 108 is adapted to impart vibrations in the detected direction of the socket 101 with respect to the adapter 104. The haptic feedback unit 108 works by providing vibration cues to guide the user in positioning the adapter 104 relative to the socket 101, based on the socket's detected location and orientation. Once the proximity detection module determines that the socket 101 is in close vicinity of the adapter 104, it sends this information to the control unit. The control unit compares the detected distance and direction with a pre-defined proximity threshold to assess the adapter's alignment. If the adapter 104 is not aligned with the socket 101, the control unit activates the haptic feedback unit 108 to produce vibrations on the adapter 104. The intensity and location of these vibrations correspond to the direction in which the socket 101 is positioned relative to the adapter 104. For instance, if the socket 101 is located to the left of the adapter 104, the haptic feedback unit 108 generates stronger vibrations on the left side of the adapter 104, signaling the user to move the adapter 104 leftward. Similarly, if the socket 101 is above or below the adapter 104, the vibrations are localized to the top or bottom sections of the adapter 104, prompting the user to adjust the adapter’s orientation accordingly.

[0035] The buzzer 109 is configured to provide audio cues to the user with respect to the direction of the socket 101 with respect to the adapter 104. The buzzer 109 typically works using a piezoelectric transducer arrangement. The piezoelectric buzzer 109 consists of a thin ceramic disc made of piezoelectric material, which has the property of generating mechanical stress when an electric current is applied to it. When the control unit sends an electrical signal to the buzzer 109, it creates an oscillating voltage that causes the piezoelectric material to expand and contract rapidly. This mechanical deformation causes the disc to vibrate, which generates sound waves at a particular frequency. The pitch of the sound depends on the frequency of the electrical signal sent to the piezoelectric element, higher frequencies produce higher-pitched sounds, and lower frequencies generate lower-pitched sounds.

[0036] A retraction unit is installed with the adapter 104 to disengage a safety shutter of the socket 101 to facilitate mounting of the adapter 104 with the socket 101. The retraction unit, comprises an articulated extendable arm 111 that is mounted over the adapter 104, an electrically insulated tip 112 formed at an end of the arm 111 to insert into the socket 101 to disengage the shutter. The articulated extendable arm 111 extends and retracts by using nested sections that slide within each other, driven by the pneumatic unit which works in the similar manner as explained above.

[0037] The electrically insulated tip 112 at the extendable arm’s end ensures the safety while disengaging the safety shutter within the socket 101. The tip 112 is designed to fit into the socket’s shutter, physically disengaging the shutter to allow the adapter 104 to be mounted securely. The electrically insulated nature of the tip 112 ensures that there is no electrical risk when the arm 111 makes contact with the socket 101, protecting both the user and the adapter 104. The tip 112 is typically made from materials that are both non-conductive and durable, preventing accidental electrical shock. When the arm 111 is extended, the insulated tip 112 moves into the socket 101, pressing against the safety shutter in a controlled manner. The extendable arm 111 places the electrically insulated tip 112 into the socket 101 to disengage the shutter, thereby permitting the adapter 104 to be attached to the socket 101.

[0038] A sensing unit is integrated with the adapter 104 to detect the presence and position of the safety shutter in the socket 101 to accordingly cause a regulation of the arm 111 to engage with the safety shutter. The sensing unit comprises an optical sensor and an inductive sensor. As the user brings the adapter 104 close to the socket 101, the optical sensor visually scans the socket 101 to determine whether a safety shutter is in place or if the socket 101 is open. The optical sensor works by visually scanning the socket 101 to detect the presence of the safety shutter. The sensor operates using light-based method, typically an infrared emitter and receiver arrangement. When the adapter 104 is brought close to the socket 101, the optical sensor emits an infrared light beam that is reflected back if there is the safety shutter, blocking the socket 101. If the sensor detects the reflection of the infrared light, this signals that the shutter is present. If the optical sensor identifies a reflected signal corresponding to the safety shutter, it alerts the system that a shutter is present.

[0039] The inductive sensor simultaneously checks for the presence of an electric field typically associated with an uncovered socket 101. The inductive sensor works by detecting the presence or absence of an electric field typically associated with the uncovered socket 101. This sensor operates based on electromagnetic induction, where the sensor generates a magnetic field and senses disruptions in that field caused by nearby conductive materials. As the adapter 104 approaches the socket 101, the inductive sensor detects whether the socket 101 is energized by the presence of the electric field. If the inductive sensor does not detect any field, the sensor indicates that the socket 101 is covered by the safety shutter. The absence of the electric field serves as a confirmation that the shutter is in place. Conversely, if the sensor detects an electric field, it suggests the socket 101 is open, and no shutter is blocking the connection.

[0040] If a safety shutter is detected and confirmed when the optical sensor identifies a physical barrier and the inductive sensor fails to detect an electric field the system activates the retraction unit. The extendable arm 111 then extends and precisely inserts the insulated tip 112 into the top hole of the safety shutter. Once properly inserted, the arm 111 lifts the shutter vertically, creating clear access to the socket 101 holes for the adapter’s prongs. To ensure correct insertion and electrical connection, a voltage sensor integrated into the adapter’s terminals detects voltage flow once the adapter 104 is plugged in. This confirms and notifies the user through audio alert and haptic feedback that the adapter 104 has been properly inserted and is ready for use.

[0041] The voltage sensor works by continuously monitoring the flow of electrical current once the adapter 104 is inserted into the socket 101. The voltage sensor preferably uses a voltage detection circuit that is connected to the prongs of the adapter 104. When the adapter 104 is plugged into the socket 101 and makes proper contact with the socket’s terminals, the circuit is completed, allowing current to flow through the adapter 104. The voltage sensor detects this flow by measuring the potential difference (voltage) between the terminals of the adapter 104 and the socket 101. If the voltage exceeds a certain threshold, indicating a successful electrical connection, the sensor confirms that the adapter 104 is properly inserted and is making contact with the socket’s power supply. Upon detecting the voltage, the sensor sends a signal to the control unit, which then triggers audio and haptic feedback to notify the user that the adapter 104 has been correctly inserted and is ready for use.

[0042] A camera 113 is embedded with the enclosure 102 to capture images of the adapter 104 approaching the socket 101 to determine the orientation of the adapter 104 with respect to the socket 101 to accordingly cause the socket 101 to rotate by means of the rotary joint 103 to align with the orientation of the adapter 104. The camera 113 comprises of an image capturing arrangement including a set of lenses that captures multiple images in vicinity of the enclosure 102, and the captured images are stored within a memory of the camera 113 in form of an optical data. The camera 113 also comprises of the processor that is integrated with artificial intelligence protocols, such that the processor processes the optical data and extracts the required data from the captured images. The extracted data is further converted into digital pulses and bits and are further transmitted to the control unit. The control unit processes the received data and determines the orientation of the adapter 104 with respect to the socket 101 to accordingly cause the socket 101 to rotate by means of the rotary joint 103 to align with the orientation of the adapter 104.

[0043] A coupling assistive unit is incorporated with the enclosure 102 to enable an automated coupling of the adapter 104 with the enclosure 102. The coupling assistive unit comprises of a housing 114 that is integrated at a front portion of the enclosure 102, a claw 115 that is installed with an inner surface of the housing 114 by means of a dual axis gantry 116 to grip the adapter 104 and insert into the socket 101 in accordance with the camera 113. The claw 115 is used to securely grip the adapter 104 for automated coupling with the socket 101. When the coupling assistive unit is activated, the claw 115 extends toward the adapter 104, guided by signals from the camera 113 that provides real-time visual feedback on the adapter's position. Once the claw 115 reaches the adapter 104, the fingers close around it, ensuring a secure grip. After securely gripping the adapter 104, the claw 115 works in coordination with the dual axis gantry 116 to position the adapter 104 correctly for insertion into the socket 101.

[0044] The dual axis gantry 116 provides the mechanical movement necessary for positioning the claw 115 and the adapter 104 with precision into the socket 101. The gantry 116 operates along two axes, typically vertical and horizontal, allowing for controlled movement in both directions. The dual axis gantry 116 is mounted on the inner surface of the housing 114 and supports the claw 115, guiding it toward the adapter 104 for accurate gripping and insertion into the socket 101. The gantry’s motion is powered by electric motors. As the claw 115 grips the adapter 104, the gantry 116 ensures that the adapter 104 is moved smoothly and accurately into alignment with the socket 101. The dual axis gantry 116 enables precise adjustments in both directions, ensuring that the adapter 104 is placed in the correct orientation and depth for successful coupling.

[0045] One or more force transducers are integrated with the gantry 116 to continuously monitor the force applied by the adapter 104 against the socket 101 to enable a regulation of the gantry 116 during the coupling of the adapter 104 with the socket 101. The force transducers operate based on the strain gauge method. Inside the transducer, strain gauges are bonded onto a flexible, elastic element such as a metal foil. When the adapter 104 applies force against the socket 101, the transducer's internal elastic element deforms proportionally to the applied force. This deformation causes a change in the electrical resistance of the strain gauges due to the strain experienced. The transducer's circuitry detects these resistance changes and converts them into an electrical signal, typically a voltage proportional to the force exerted. This real-time electrical output is then monitored continuously, allowing the system to regulate the gantry’s movement during the coupling process to ensure precise and controlled engagement of the adapter 104 with the socket 101.

[0046] A sensing module is embedded in the enclosure 102 to continuously monitor the socket 101 for defects to cause the alert unit to warn the user regarding a defective socket 101. The sensing module comprises a colour sensor to detect visual anomalies including discoloration, darkened areas indicating burnt socket 101, and a humidity sensor monitor to detect the presence of moisture near the socket 101. The colour sensor within the sensing module operates based on the reflected light method. The sensor emits specific wavelengths of light onto the surface of the socket 101. The sensor then measures the intensity of the reflected light for each wavelength. Variations in the reflected light intensity indicate differences in color or discoloration on the socket's surface. By analyzing these reflected signals, the sensor detects visual anomalies such as discoloration or darkened areas, which suggest issues like burning or damage. This information is processed to determine the presence of visual defects, triggering alerts if abnormalities are identified.

[0047] The humidity sensor functions using the capacitive sensing principle. The sensor has two conductive plates separated by a dielectric material whose properties change with moisture levels. When moisture is present near the socket 101, it affects the dielectric constant of the material between the plates, causing a change in the capacitance value. The sensor detects these variations in capacitance and converts them into an electrical signal. An increase in moisture results in a measurable change in the sensor's capacitance, allowing the system to monitor humidity levels accurately. If elevated moisture is detected, the system activates alerts to warn of potential issues.

[0048] If either sensor detects a hazardous condition such as the burnt socket 101 or excessive humidity the system immediately issues an alert to the user. The alert is communicated through the haptic feedback (vibration), audio cues (e.g., "Warning: unsafe socket detected") and the Braille warning pattern that is displayed on the braille output unit 107. These alerts inform the user to avoid attempting to insert the adapter 104 and to seek assistance or use a different socket, ensuring the user safety in potentially dangerous conditions.

[0049] The present invention works best in the following manner, where the rotatable electrical socket 101 receives power from the power source that is housed within the enclosure 102 by means of the rotary joint 103. The rotary joint 103 is the circular sliding unit. The mesh network module interconnecting the plurality of the sockets where this mesh network module is based on the communication unit, operating over the communication protocol selected from Bluetooth, Wi-Fi and the combination thereof. The plug-in adapter 104 to couple with the socket 101 to supply power to the electrical unit. The proximity detection module detects the adapter’s presence and direction in the vicinity of the nearest socket 101 in accordance with the mesh network. The proximity detection module comprises of the ultrasonic transducer 105 that is installed with the socket 101 and the ultrasonic receiver 106 that is mounted with the adapter 104. The alert unit generates the alert for the user and upon detection of the socket 101 being in close vicinity of the adapter 104 as determined by the proximity detection module, the alert unit guides the user to position the adapter 104 in alignment with the socket 101. The close proximity distance is pre-defined within the control unit that is associated with the system. The alert unit comprises one or more of the braille output unit 107, the haptic feedback unit 108 and the audio buzzer 109. The braille output unit 107 comprises the grid of pneumatic pins 110 that is arranged over the surface of the adapter 104 to indicate the direction of the socket 101 with respect to the adapter 104. The grid of pneumatic pins 110 is selectively extended and retracted to form braille characters.

[0050] In continuation, the haptic feedback unit 108 is adapted to impart vibrations in the detected direction of the socket 101 with respect to the adapter 104. The buzzer 109 provides audio cues to the user with respect to the direction of the socket 101 with respect to the adapter 104. The detection module configured with the control unit receives the parameters of the ultrasonic waves transmitted and received by the proximity detection module to determine the distance and the direction of the socket 101 with respect to the adapter 104. The retraction unit disengages a safety shutter of the socket 101 to facilitate mounting of the adapter 104 with the socket 101. The retraction unit comprises the articulated extendable arm 111 and the electrically insulated tip 112 to insert into the socket 101 to disengage the shutter. The sensing unit detects the presence and position of the safety shutter in the socket 101 to accordingly cause the regulation of the arm 111 to engage with the safety shutter. The sensing unit comprises the optical sensor and the inductive sensor. The camera 113 captures the images of the adapter 104 approaching the socket 101 to determine the orientation of the adapter 104 with respect to the socket 101 to accordingly cause the socket 101 to rotate by means of the rotary joint 103 to align with the orientation of the adapter 104. The coupling assistive unit enables the automated coupling of the adapter 104 with the enclosure 102. The coupling assistive unit comprises of the housing 114 that is integrated at the front portion of the enclosure 102, the claw 115 that is installed with the inner surface of the housing 114 by means of the dual axis gantry 116 to grip the adapter 104 and insert into the socket 101 in accordance with the camera 113. One or more force transducers continuously monitor the force applied by the adapter 104 against the socket 101 to enable the regulation of the gantry 116 during the coupling of the adapter 104 with the socket 101. The sensing module continuously monitors the socket 101 for defects to cause the alert unit to warn the user regarding the defective socket 101. The sensing module comprises of the colour sensor to detect visual anomalies including discoloration, darkened areas indicating burnt socket 101 and the humidity sensor monitor to detect the presence of moisture near the socket 101.
