DESC:TECHNICAL FIELD
[0001] The present disclosure relates to a quick response (QR) powered system and relates to a QR code system for smart management of gas cylinders. More particularly, the present disclosure relates to reordering of the gas cylinders, enabling application-free consumer access, and automated operational tracking.

BACKGROUND
[0002] Generally, the distribution of gas for household and/or commercial purposes is provided using a gas cylinder. For example, a supply of gas cylinders to a household for cooking, or an oxygen cylinder to a hospital, and the like.
[0003] Conventional gas cylinder management systems suffer from several persistent technical limitations that impact operational efficiency, data integrity, traceability, and user interaction. One major challenge lies in the lack of an automated, scalable mechanism to accurately record and update refilling information associated with individual gas cylinders in real time. Typically, the recording of refill status or tracking of gas cylinder usage is either performed manually or through barcodes requiring close-proximity handheld scanners. The conventional techniques are labor-intensive, prone to error, and are poorly suited for high-throughput environments like bottling plants or refilling facilities, where large volumes of gas cylinders are processed quickly. Thus, an absence of reliable, automated identification and refill tracking further creates traceability gaps in the gas cylinder supply chain, affecting compliance, inventory forecasting, and distribution management.
[0004] Another technical problem arises in the physical disposition and durability of identification labels or tracking mechanisms on the gas cylinders. Due to the gas cylinder’s shape (i.e., cylindrical and rugged structure), traditional placements of any identification codes for instance, on the body or bottom of the gas cylinder may make the identification code susceptible to wear, smudging, or obstruction, thereby reducing scanning reliability and increasing the likelihood of unreadable or damaged identifiers.
[0005] Furthermore, the placement of the identification codes may result in failure to consider optical visibility angles required by automated vision systems, which are increasingly employed in industrial automation workflows. Thus, even in setups where cameras are introduced, the cameras often fail to consistently scan the identification codes, leading to interrupted automation and data inconsistencies.
[0006] A further challenge pertains to user engagement and reorder mechanisms. In the absence of a seamless interface tied to each physical gas cylinder, users are often required to manually enter identification numbers or navigate through complex ordering portals to request refills. This creates friction in user experience, increases error margins, and is not conducive to widespread adoption of digital refill systems, particularly in semi-urban or industrial contexts where ease of use is paramount.
[0007] The present disclosure addresses the above-discussed technical challenges through a novel technique involving a strategically disposed quick response (QR) code on a body part of the gas cylinder and a corresponding vision-based monitoring infrastructure. The body part i.e., a shoulder region of the gas cylinder provides an inclined surface that naturally aligns with the field of view of a vision-based monitoring camera positioned at the refilling facility. Advantageously, the positioning improves the scan accuracy and visibility under varying light and movement conditions. Moreover, because the shoulder is situated below a neck of the gas cylinder, the neck acts as a protective overhang, thus shielding the QR code from physical wear, debris, and handling damage. Thereby, the strategic disposition of the QR code significantly improves the longevity and reliability of the identifier (i.e., the QR code). Hence, the present disclosure solves the technical problem of ensuring both optical visibility and physical durability of a tracking mechanism (e.g. scanning the QR code).
[0008] Further, the existing/conventional techniques have failed to provide techniques to retrieve and display updated status directly via a web interface, thus reducing the need for on-device software or manual entry.
[0009] The present disclosure introduces an architecture with technical advantages that enables secure, durable, and automation-friendly tracking of a status of the gas cylinder, while also enhancing user experience through seamless interface integration and digital reorder capabilities. The present disclosure provides technical solution (i.e., the QR code based system) that updates a backend database with filling status and timestamp. Thereby, enhancing transparency for the customer and enable access to verified cylinder details, thereby reducing the risk of counterfeiting. Hence, the present disclosure effectively solves multiple long-standing problems in the gas cylinder management process.

SUMMARY
[0010] This summary is provided to introduce a selection of concepts, in a simplified format, that are further described in the detailed description of the invention. This summary is neither intended to identify key or essential inventive concepts of the invention nor is it intended for determining the scope of the invention.
[0011] In an embodiment of the present disclosure, a quick response (QR) code system for smart management of gas cylinders is disclosed. The system includes a QR code disposed on a body portion of a gas cylinder. The QR code is positioned for convenient scanning, wherein the QR code encodes link-data redirecting to a web interface hosted on a remote server. The web interface is configured to display recent filling information associated with the gas cylinder., a vision based monitoring camera, or a camera module of a smart user device. The recent filling information is being stored and updated on the remote server based on data captured during scanning, via a monitoring camera, at a refilling facility, and provides a one-click reorder option for requesting gas cylinder refills via an on-demand service framework.
[0012] Accordingly, the present disclosure may enable placing the re-orders request for the gas cylinder without the requirement of installation of any additional application. Accordingly, the tiresome conventional steps of navigating through an installed additional application are effectively prevented.
[0013] Further, the operation of placing the re-order request for the gas cylinder may be triggered directly in response to scanning the QR code attached to the gas cylinder. Accordingly, there is no need to store contact details associated with the gas company or its distributor for placing the re-order request for the gas cylinder. This may also eliminate the requirement of calling the distributor of the gas company, where the user may repeatedly provide address, size, and other information each time they place a re-order request. Thus, the present disclosure makes the placement of the re-order request for the gas cylinder quicker, and simpler for the user.

[0029] Embodiments of the present disclosure will be described below in detail with reference to the accompanying drawings.
[0030] Figure 1a illustrates a block diagram depicting an environment of implementation of a quick response (QR) code system 100 (may alternatively referred as system 100 for the sake of brevity) for smart management of gas cylinders, according to an embodiment of the present disclosure. As shown, the environment of the system 100 may include a Quick Response (QR) code 102, a gas cylinder 104, a smart user device 106, and a server 108.
[0031] The QR code 102 may be pre-attached to the existing gas cylinder 104 available with a user. The gas cylinder 104 shown in Figure 1 may be an existing gas cylinder 104 available with the user that may require refilling. In an example embodiment, the QR code 102 may be attached to the gas cylinder 104 with an adhesive, for example, the QR code 102 as a sticker attached to the gas cylinder 104. In another example embodiment, the QR code 102 may be a pre-laser printed metal tag glued on a body of the gas cylinder 104. In a preferred embodiment, the QR code 102 attached to the gas cylinder 104 may be weatherproof.
[0032] Further, the QR code 102 may include a web-link with an embedded identification code. The embedded identification code may be unique to the gas cylinder 104 having attached thereto the QR code 102. The embedded identification code may include one of, an alphanumeric string and a numerical identifier. Further, the web-link may be associated with information related to a gas company/distributor/agency, required for placing and accepting the re-order request for the gas cylinder 104 having attached thereto the QR code 102.
[0033] The smart user device 106 may be a camera enabled device and may be adapted to scan the QR code 102 using a camera module of the smart user device 106. In an embodiment, the smart user device 106 may be adapted with a smart operating system capable of scanning and processing the QR code 102. For example, the smart user device 106 may include one of, a smartphone, a tablet, and the like devices configured with the smart operating system. The smart user device 106 may be adapted to communicate with the server 108 over a network.
[0034] In the illustrated embodiment, the QR code 102 may be attached to a body portion or an external body of the gas cylinder 104. The body portion may indicate one of, a shoulder, a top-facing surface, an inside portion of a neck portion, or a concave upper recess of the gas cylinder 104, within the scope of the present disclosure.
[0035] Accordingly, the QR code 102 disposed at on one of, the shoulder or the top-facing surface of the gas cylinder 104, the placement of the QR code 102 may facilitate proper visibility and ease of scanning by the smart user device 106. Further, the QR code 102 may be disposed at on one of, the inside portion of the neck of the gas cylinder 104, or to the concave upper recess of the gas cylinder 104, such placement of the QR code 102 may protect the QR code 102 from physical abrasion, environmental exposure, and unauthorized tampering while remaining scannable by the overhead cameras or the smart user device 106.
[0036] Further, the placement of the QR code 102 discussed above may also facilitate scanning of the QR code 102 at a refilling facility or a bottling plant by overhead cameras provided on a conveyor belt of conveyor-based systems at the bottling plant. Further, at the bottling plant conveyor belt, scanning by the overhead cameras may further facilitate automatic updating or retrieval of metadata including at least one of inventory status, cylinder type, filling status, filling date and time, last known status, a filling station and/or the bottling plant details with the distributor or the gas company. Further, scanning by the overhead cameras may also conduct a verification of whether the gas cylinder 104, having attached thereto the QR code 102, is authentic and/or has been received by the correct bottling plant. Therefore, the disclosed placement of the QR code 102 on the gas cylinder 104 may enhance traceability and transparency for both operators at the bottling plant and the end-users.
[0037] The camera module of the smart user device 106, may be configured to scan the QR code 102, and consequently, the web-link is generated. In one example embodiment, the user may manually select the web-link, and this is redirected to a browser application on the smart user device 106. In another example embodiment, the web-link is automatically redirected to the browser application on the smart user device 106 in response to scanning the QR code 102. In particular, the smart user device 106, in response to scanning the QR code 102, may redirect to a user interactive web interface 204 (shown in Figure 2) running on the server 108 using the browser application in the smart user device 106. In one example, the browser application may be a native application preinstalled in the smart user device 106. Further, the user interactive web interface 204 may be configured with a provision for placing the re-order request of the gas cylinder 104 in a single click. The user interactive web interface 204 is explained in detail with respect to Figure 2.
[0038] Figure 1b illustrates a block diagram depicting another environment of implementation of the QR code system for the smart management of the gas cylinders, according to an embodiment of the present disclosure.
[0039] In an embodiment, Figure 1b illustrates another implementation of the placement of the QR code 102 on the gas cylinder 104, particularly in the context of a refilling facility or bottling plant equipped with a monitoring camera 112. In the implementation, the gas cylinder 104 (multiple) may be placed (e.g. sequentially) on the conveyor belt 110, which is configured to transport the cylinders through an automated refilling line. The monitoring camera 112, implemented as a vision-based smart camera, is positioned above the conveyor belt and is in communication with the remote server 108 (or the server). The monitoring camera 112 is configured to scan the QR code 102 affixed to the gas cylinder 104 during the refilling process.
[0040] Advantageously, the QR code 102 is disposed on the shoulder region of the gas cylinder 104. The shoulder provides an inclined or slanted surface, enhancing the visibility of the QR code 102 for the monitoring camera 112. The strategic inclination of the QR code 102 allows for reliable scanning even when the gas cylinder 104 is moving along the conveyor path, thereby increasing scanning accuracy and throughput. Moreover, the shoulder region is positioned immediately below a neck portion of the gas cylinder 104. The neck portion functions as a protective overhang, shielding the QR code 102 from physical abrasion, environmental exposure, or accidental damage during handling and transportation, while still maintaining unobstructed visibility to the monitoring camera.
[0041] Further, upon successfully scanning the QR code 102, the monitoring camera 112 transmits a signal to the remote server 108, enabling the remote server 108 to automatically update the recent filling information associated with the corresponding gas cylinder 104. As a result, any user subsequently scanning the same QR code using the smart user device 106 (as illustrated in Figure 1a) is redirected to the web interface displaying the updated filling information, along with a one-click reorder option facilitated by an on-demand service framework.
[0042] In an example scenario, a gas bottling plant is configured with a vision-based monitoring camera 112 mounted above a conveyor system. As each gas cylinder 104 reaches the refill station, the monitoring camera 112 scans the QR code positioned on the shoulder of the gas cylinder 104. For instance, the gas cylinder with the QR code 102 is detected and scanned. The embedded identification code in the QR code 102 is sent to the remote server 108, which records the timestamp and status of the refill. When an end-user later scans the same QR code 102 using their smartphone 106, the web interface shows that the gas cylinder was refilled on “02 July 2025, 10:30 AM” and presents a reorder button. In an advantageous aspect, the above-described process eliminates manual data entry, reduces errors, and enhances traceability across the gas cylinder management and supply chain.
[0043] Figure 2 illustrates a block diagram depicting the smart user device 106 depicting the web interface for displaying recent filling information and a one-click reorder option for the smart management of the gas cylinders, according to an embodiment of the present disclosure.
[0044] As shown, the smart user device 106 is redirected to the web interface 204 which is user interactive on a screen 202 of the smart user device 106 using the browser application, in response to scanning the QR code 102.
[0045] Further, the web interface 204 may be configured to display the one-click reorder option 206, on the web interface 204 for management of the gas cylinder 104, particularly for requesting gas cylinder refills via an on-demand service framework. Here, the one-click reorder option 206 may indicate a user-interface (UI) element adapted to receive the re-order request from the user. The one-click reorder option 206 receives a user input indicative of a selection, thereby placing a re-order request for the gas cylinder 104
[0046] In an alternative embodiment, the user interactive web interface 204 may, along with the one-click reorder option 206, is configured to display the recent filling information 208 corresponding to the gas cylinder 104 having attached thereto the QR code 102. The recent filling information may include time of filling of the gas cylinder 104 having attached thereto the QR code 102, location of the nearest plant, and type of cylinder, such as a commercial or residential cylinder.
[0047] In an embodiment, the web interface 204 may further be configured to generate a modification option (not shown) on the web interface 204 for modifying a quantity of the gas cylinder 104, in response to an authentication of the user on the user interactive web interface 204. Further, the modification option may indicate the user-interface (UI) element adapted to receive a modification request. Here, the authentication may include login initiated by the user on the user interactive web interface 204 using a registered user’s credentials. Alternatively, the authentication may be initiated via an OTP sent to the registered user’s mobile number. Furthermore, the web interface 204 may be configured to generate the re-order request for the gas cylinder 104 based on the modified quantity of the gas cylinder 104 upon successful authentication.
[0048] Accordingly, the present disclosure may enable placing the re-order request of the gas cylinder 104 without the requirement of installation of any additional application. Accordingly, the tiresome conventional steps of navigating through an installed additional application are effectively prevented.
[0049] Further, the operation of placing the re-order request for the gas cylinder 104 may be triggered directly in response to scanning the QR code 102 attached to the gas cylinder 104. Accordingly, there is no need for storing contact details associated with the gas company or its distributor for placing the re-order request for the gas cylinder 104. This may also eliminate the requirement of calling the distributor of the gas company, where the user may repeatedly provide an address, size, and other information each time they place the re-order request. Thus, the present disclosure makes the placement of the re-order request for the gas cylinder 104 quicker and simpler for the user.
[0050] Figure 3 illustrates an example block diagram for generating the re-order request of the gas cylinder 104, according to an embodiment of the present disclosure.
[0051] The server 108 is configured to receive the re-order request for the gas cylinder 104 in response to the scanning of the QR code 102 attached to the gas cylinder 104. In a non-limiting embodiment, the server 108 may be in communication with the on-demand service framework or an order management system for generating the re-order request of the gas cylinder 104. The server 108 may further include at least one processor 302, memory 304, modules 306 and database 308. The at least one processor 302 may be communicatively coupled with the memory 304. The modules 306 and the memory 304 may be coupled to the at least one processor 302.
[0052] The at least one processor 302 can be a single processing unit or several units, all of which could include multiple computing units.

Among other capabilities, the at least processor one 302 is adapted to fetch and execute computer-readable instructions and data stored in the memory 304.
[0053] The memory 304 may include any non-transitory computer-readable medium known in the art including, for example, volatile memory, such as static random-access memory (SRAM) and dynamic random-access memory (DRAM), and/or non-volatile memory, such as read-only memory (ROM), erasable programmable ROM, flash memories, hard disks, optical disks, and magnetic tapes.

[0055] In an embodiment, the at least processor one 302 may be configured to receive an input signal transmitted by the smart user device 106 in response to scanning the Quick Response (QR) code 102. The QR code 102 may include the web-link having the embedded identification code. The embedded identification code may be unique to the gas cylinder 104 having attached thereto the QR code 102. In an embodiment, the web-link having the embedded identification code may include one of, an alphanumeric string and a numerical identifier. In an embodiment, the web-link having the embedded identification code comprises one of, an alphanumeric string and a numerical identifier. In one example, the QR code 102 may be attached to one of, an external body of the gas cylinder 104, a shoulder, a top-facing surface, an inside portion of a neck portion, or a concave upper recess of the gas cylinder 104.
[0056] Further, the at least processor one 302 may be configured to associate the scanned QR code 102 with a pre-linked gas cylinder and a corresponding user profile from a storage database based on the embedded identification code. In an embodiment, the pre-linking of the gas cylinder 104 with the corresponding user profile may be done at the time of the previous delivery of the gas cylinder 104 by distributor personnel. Accordingly, the information associated with the previous delivery of the gas cylinder 104 and the corresponding user profile corresponding to the previous delivery of the gas cylinder 104 may be stored in the database on the server 108. In a non-limiting embodiment, the information associated with the user profile corresponding to the pre-linked gas cylinder 104, stored in the database on the server 108, may include customer’s address, specification of gas cylinder size, previous order details, etc. Here, the pre-linked gas cylinder corresponds to the gas cylinder 104 having attached thereto the QR code 102.
[0057] Further, the at least processor one 302 may be configured to transmit the user interactive web interface 204 to the smart user device 106 based on the associated pre-linked gas cylinder and the corresponding user profile.
[0058] Further, the at least processor one 302 may be configured to transmit the re-order option 206 on the user interactive web interface 204 for placing the re-order request corresponding to the scanned QR code 102. The re-order option 206 may indicate the user-interface (UI) element adapted to receive the re-order request.
[0059] Further, the at least processor one 302 may be configured to generate the re-order request for the gas cylinder 104 when the re-order option 206 receives the user-input indicative of a selection thereby placing the re-order request of the gas cylinder 104.
[0060] In an embodiment, the at least processor one 302 may further be configured to authenticate the identity of the user on the user interactive web interface 204. Further, the at least processor one 302 may be configured to transmit a modification option on the user interactive web interface 204 for modifying a quantity for re-order of the gas cylinder 104 in response to an authentication of the user. Further, the at least processor one 302 may be configured to generate the re-order of the gas cylinder 104 based on the modified quantity of the gas cylinder 104 upon successful authentication.
[0061] In an embodiment, the at least one processor 302 may be configured to validate the eligibility of the gas cylinder 104 to place the re-order request based on a duration of a predefined interval since the last order date, prior to generating the re-order option 206 on the user interactive web interface 204 for placing the re-order request.
[0062] In an embodiment, the at least one processor 302 may be configured to transmit a notification to a remote system in response to the placement of the re-order request of the gas cylinder 104. In an embodiment, the remote system may correspond to at least one of a logistic management system and a dealer management system for dispatching the gas cylinder 104.
[0063] Figure 4 illustrates a block diagram depicting an operation flow for generating the re-order request of the gas cylinder 104, according to an embodiment of the present disclosure. Here, block 402 to block 406 may operate at front end, and block 408 may operate at backend. Further, the block 410 may operate from a remote location.
[0064] At block 402, the user may scan the QR code 102 attached to the gas cylinder 104 using the camera module of the smart user device 106. The QR code 102 may be attached to the gas cylinder (104) and may include the web-link with an embedded identification code. The embedded identification code may be unique to the gas cylinder 104 having attached thereto the QR code 102.
[0065] At block 404, the smart user device 106, in response to scanning the QR code 102, may trigger a browser application in the smart user device 106 and may redirect the browser application to the user interactive web interface 204 corresponding to the web-link.
[0066] At block 406, the web interface 204 may be in communication with the server 108. In an embodiment, the user interactive web interface 204 may run on the server 108 and may be accessible to the user via the browser application on the smart user device 106. Further, the web interface 204 may request the server 108 for information associated with a pre-linked gas cylinder and a corresponding user profile from a storage database based on the embedded identification code.
[0067] Subsequent operations may be performed at the backend prior to returning the operation to the front end, where at block 408, the server 108 may process the request raised by the user interactive web interface 204 corresponding to the scanned QR code 102. Accordingly, the server 108 may associate the embedded identification code of the scanned QR code 102 with the pre-linked gas cylinder and the corresponding user profile from the storage database. Here, the pre-linked gas cylinder corresponds to the gas cylinder 104 having attached thereto the QR code 102. Further, the server 108, based on the requested information, may transmit the re-order option 206 to the user interactive web interface 204 for placing the re-order request corresponding to the scanned QR code 102.
[0068] Further to the transmission of the re-order option 206 to the user interactive web interface 204, the operation may return to the front end, where at block 406, the web interface 204 may generate the one-click reorder option 206 for placing the re-order request. Here, the one-click reorder option 206 may indicate the user-interface (UI) element adapted to receive the re-order request. Further, the re-order option 206 may be accessible to the user on the user interactive web interface 204, and the operation may continue further on receiving a selection from block 402.
[0069] Further, at block 403, the user may select the one-click reorder option 206, sending the input to the user interactive web interface 204 for placing the re-order request for the gas cylinder 104.
[0070] Further, at block 404, the web interface 204, on receiving the user-input indicative of the selection, may generate the re-order request or the request for gas cylinder refills on the server 108.
[0071] Here onwards, the operation may further move to the backend, where at block 408 the server 108 may receive the re-order request and may transmit the same to the on-demand service framework. The on-demand service framework may correspond to at least one of the logistic management systems and the dealer management system for dispatching the gas cylinder 104.
[0072] Furthermore, at block 410, the remote system may dispatch the gas cylinder 104 in response to the placed re-order request for the gas cylinder 104. Further, the remote system may notify the user of confirmation of the placed re-order request for the gas cylinder 104 via an electronic communication. For example, the electronic communication may correspond to a short messaging service (SMS), an electronic mail (E-mail), and the like.
[0073] Some of the advantages of the present disclosure are as follows:
