Description

TECHNICAL AREA OF INVENTION

[0001] The invention relates to the provision of assembly information for the assembly of structures, such as furniture, from building elements, such as custom-made profiles. BACKGROUND OF THE INVENTION

[0002] The assembly of structures from prefabricated components is a widespread practice in various sectors, from the furniture industry to construction. Traditionally, this process is carried out using printed blueprints and assembly instructions. While this method has proven itself over decades, it has some inherent disadvantages that become more apparent as the complexity of the structures to be assembled increases.

[0003] A common method involves assembling components for furniture or other structures using a printed assembly plan. The individual components are often marked with numbers or other symbols to make them easily identifiable. This method is intended to simplify the assembly process and prevent mix-ups. However, experience shows that, especially with components that look very similar, a paper-based, two-dimensional representation often leads to misunderstandings and errors.

[0004] The limitations of this conventional method become particularly apparent with more complex structures or when a large number of similar components are used. Assemblers must constantly switch back and forth between the physical component and the construction plan, which is time-consuming and increases the potential for errors. Furthermore, two-dimensional representations often fail to adequately illustrate the spatial relationships between the components, which can lead to misinterpretations.

[0005] Another problem lies in the rigidity of printed instructions. Once printed, they cannot be adapted to unforeseen situations or the individual needs of the installer. This can lead to frustration and wasted time, especially during complex installations, if the installer requires additional information not included in the printed material.

[0006] Furthermore, managing and updating paper-based documentation presents a challenge. Changes or improvements to the product design often require reprinting and redistributing entire batches of manuals, which can be both costly and environmentally damaging.

[0007] The increasing digitalization in all areas of life has not stopped at the assembly industry. Initial approaches to digitizing assembly instructions, such as providing PDF documents or simple apps, have brought some improvements, but do not solve all the problems of paper-based systems. They often lack true interactivity or context-sensitive help and do not fully utilize the potential of modern technologies.

[0008] Another aspect often neglected in conventional assembly methods is quality assurance during the assembly process. Errors are frequently only discovered after assembly is complete, which can lead to time-consuming and costly corrections. A system capable of detecting and correcting errors in real time would represent a significant advancement. REVELATION OF THE INVENTION

[0009] In light of the above considerations, there is a clear need for innovative solutions that make the assembly process more efficient, accurate and user-friendly.

[0010] The invention is based on the objective of providing a system that allows assembly information to be provided automatically and precisely when assembling components into a structure, wherein the components are uniquely identifiable and the assembly information is presented in a user-friendly, interactive manner.

[0011] The problem is solved by a system having the features of claim 1. Advantageous embodiments and further developments are the subject of the dependent claims. Dependent claim 14 relates to a mobile terminal for use with a system according to the invention. Dependent claim 17 relates to a component for use with a system according to the invention.

[0012] A system according to the invention comprises a storage unit with a digital blueprint of the structure, a capture unit for capturing the identification code of a component, at least one data processing unit coupled to the storage unit for identifying the component as part of the structure based on the captured identification code, for determining the assembly position of the identified component in the digital blueprint, and for generating assembly information relating to the identified component, and a display device for displaying the assembly information, wherein the assembly information includes at least the assembly position of the component. This system enables seamless integration of digital information and physical assembly.

[0013] In a preferred embodiment, the acquisition unit and the display device are part of a mobile device. This increases the flexibility and mobility of the system and enables easy integration into existing workflows.

[0014] Another embodiment provides that the data processing unit is also part of the mobile device. This enables the system to operate autonomously without dependence on external computing resources.

[0015] Alternatively, the data processing unit can also be implemented as an external unit that communicates with the mobile device. This allows the use of more powerful computing resources for complex calculations. In this configuration, the mobile device primarily handles data acquisition (e.g., scanning identification codes) and the display of assembly information, while the computationally intensive tasks are performed by a more powerful external system.

[0016] Communication between the mobile device and the external data processing unit can take place via various network technologies, such as Wi-Fi, cellular networks, or, in industrial environments, via special IoT protocols. This enables real-time processing of complex data, such as the dynamic adaptation of the digital blueprint or the execution of sophisticated AI algorithms, without overloading the resources of the mobile device.

[0017] Another advantage of this configuration is the ability to utilize centrally stored and constantly updated databases. This allows, for example, the latest versions of blueprints, optimized assembly sequences, or aggregated insights from numerous assembly processes to be directly incorporated into the instructions displayed to the user. Furthermore, this architecture facilitates easier system scaling, as upgrades or expansions to processing capacity can be performed centrally without requiring modifications to individual mobile devices.

[0018] In another embodiment, the assembly information includes a three-dimensional representation, in particular an exploded view. This improves the user's spatial understanding of the assembly structure.

[0019] An additional embodiment provides that the assembly information includes a note if the identified component is not currently being assembled. This prevents assembly errors due to incorrect sequence.

[0020] In another embodiment, the assembly information includes a color highlighting of the determined assembly position. This facilitates the visual identification of the correct assembly position.

[0021] An additional embodiment provides that the data processing unit performs an initial completeness check of the available components. This ensures that all necessary parts are present before assembly begins.

[0022] In another embodiment, the system comprises a detection unit for recording the completed structure and a comparison unit for comparing it with a target structure. This enables final quality control.

[0023] An additional embodiment includes a guide generation unit for generating step-by-step assembly instructions. This provides the user with detailed instructions for the entire assembly process.

[0024] In another embodiment, the system includes a feedback unit for processing user input to confirm completed assembly steps. This enables precise tracking of the assembly progress.

[0025] An additional embodiment includes an AI-supported learning and optimization module that analyzes and optimizes data from past assembly processes. This enables continuous improvement of the assembly process based on collected experience and data.

[0026] A mobile device according to the invention for use with the system is configured to capture the machine-readable identification code of a component and display assembly information. This enables flexible and mobile use of the system, allowing the assembly process to be carried out at different locations.

[0027] In a preferred embodiment, the mobile device is further configured to send the captured identification code to an external data processing unit and to receive assembly information from the external data processing unit. This allows the use of powerful external computing resources without impairing the mobility of the device.

[0028] Another embodiment provides that the mobile device is configured to process the captured identification code, identify the corresponding component in a digital blueprint, determine the component's mounting position, and generate assembly information. This enables the mobile device to operate autonomously, which is particularly advantageous in environments without a reliable network connection.

[0029] A component according to the invention for use with the system comprises a base structure designed to be part of an overall structure to be assembled, and a machine-readable identification code attached to the base structure for identifying the component. This enables seamless integration of the physical component into the digital assembly process and facilitates precise identification and positioning during assembly.

[0030] In a preferred embodiment, the machine-readable identification code is a barcode, matrix code, or a code stored in an RFID tag. This offers flexibility in the choice of identification technology and allows adaptation to various application scenarios.

[0031] The invention also allows the implementation of a computer-implemented method for the automated provision of assembly information during the assembly of components, each bearing a machine-readable identification code, into a structure. Such a method comprises generating a digital blueprint of the structure, capturing the identification code of a component and identifying the component as part of the structure, determining the assembly position of the identified component in the digital blueprint, generating assembly information relating to the identified component, and displaying the assembly information on a display device, wherein the assembly information includes at least the assembly position of the component. This enables precise and efficient assembly through the direct linking of physical components with their digital representations.

[0032] In a preferred embodiment of the method made possible by the invention, the display of the assembly position includes a representation of the identified component in a three-dimensional view, in particular an exploded view of the structure. This has the advantage that the user gains a clear spatial understanding of the assembly position, which reduces errors and increases assembly speed.

[0033] Another preferred implementation of the method made possible by the invention includes issuing a notification if the identified component is not currently being assembled. This prevents assembly errors caused by premature or incorrect placement of components.

[0034] In another preferred implementation of the method made possible by the invention, the display of the assembly information includes color-coding the determined assembly position of the identified component in the digital blueprint. This facilitates the visual identification of the correct assembly position and reduces the cognitive load on the user.

[0035] In another preferred embodiment of the method made possible by the invention, the display device is part of a mobile device, and at least the step of capturing the machine-readable identification code and displaying the assembly information is performed using the mobile device. This increases flexibility and mobility during the assembly process.

[0036] Another preferred implementation of the method made possible by the invention includes a step of initial completeness testing of the existing components with regard to their structure. This ensures that all necessary parts are present before the assembly process begins and avoids interruptions due to missing parts.

[0037] Another preferred implementation of the method made possible by the invention comprises the step of a final acquisition, in particular image acquisition, of the structure created from the components and a comparison of the acquired structure with a target structure. This enables a final quality control and ensures that the assembly has been completed correctly.

[0038] Another preferred implementation of the method made possible by the invention involves generating step-by-step assembly instructions based on the digital blueprint. This provides the user with detailed and structured instructions for the entire assembly process.

[0039] Another preferred implementation of the method made possible by the invention involves capturing and processing user input to confirm a completed assembly step. This allows for precise tracking of the assembly progress and dynamic adjustment of the instructions.

[0040] Another preferred implementation of the method made possible by the invention includes generating additional assembly information such as tool requirements, safety instructions, and component specifications. This increases the safety and efficiency of the assembly process.

[0041] Another preferred implementation of the method made possible by the invention includes a feedback step for capturing user input after completion of the structure. This enables continuous improvement of the system based on user experience.

[0042] Further details and advantages of the invention will become apparent from the following purely exemplary and non-limiting description of an embodiment in conjunction with the drawing comprising two figures. BRIEF DESCRIPTION OF THE DRAWING Fig. Figure 1 is a highly schematic overview diagram to explain the essential elements of the invention in one of many possible embodiments. Fig. Figure 2 shows one possible way of displaying assembly information. DESCRIPTION OF PREFERRED DESIGNS

[0043] The Fig. Figure 1 shows a highly schematic representation of elements for realizing one embodiment of the invention. Fig. Figure 1 shows a situation in which a component 12 equipped according to the invention with a machine-readable identification code 10, which may, for example, be a custom-made aluminum profile, is connected to other components 14 already installed at the time shown, each of which also bears a machine-readable identification code 16, of which in the Fig. 1. Not all components have been assigned a reference number and are to be assembled into a structure 18. Note that although all already installed components 14 have been assigned the same reference number, they can, of course, be different components. If the structure to be assembled is, for example, a shelf, there will typically be several identical components, but also many differing components. It may be intended that the identical components also bear identical identification codes, so that two identical components cannot be distinguished by their identification code. However, it may also be intended, for example for documentation purposes, that even structurally identical components bear different identification codes.

[0044] The identification codes can be, for example, barcodes or matrix codes, which, depending on the component used and the structure to be created, can be affixed or laser-etched. For certain structures, it is desirable to avoid having the codes visible in the fully assembled state, which is why easily removable adhesive labels are used. The codes can also be stored in RFID chips that are either affixed or otherwise attached. Ultimately, the only important factor is that the codes are machine-readable.

[0045] In the illustrated embodiment, the identification code 10 is captured by means of a mobile device 20, which can be, for example, a tablet computer or a smartphone. If the identification code 10 is, for example, a matrix code, it can be captured by means of a camera built into the device in a manner known per se. Using such a code, it is also possible to start applications on the device 20 automatically or semi-automatically, in particular to call up a so-called app, which then interacts with the user, especially via a display 22, which also serves as a display device according to the invention. Since the computing power of modern devices is sufficiently high, the steps described below can be carried out entirely on the device 20 using a corresponding app.In the example shown, however, the terminal device 20 connects wirelessly via the internet 24 to a separate data processing unit 26 and sends the captured identification code 10 of the component 12 to it. The data processing unit 26 is connected to a storage unit 28, which is shown in the schematic diagram. Fig. 1 is drawn as a separate unit, which can of course also be part of the data processing unit 26.

[0046] A digital blueprint for structure 18 is stored in the storage unit 28. If the user has entered an identification code using the terminal device 20, this code is transmitted to the data processing unit 26, which then identifies the component and checks whether it is part of the structure 18 to be assembled, i.e., whether it should be added to the already installed components 14. If this check determines that the component 10 does not belong to the structure 18 or should not be installed at this time, the data processing unit 26 generates a corresponding message and sends it via the internet 24 to the terminal device 20, where it is displayed on the screen 22.Conversely, if the component 10 is a component that is currently to be installed, the data processing unit 26 generates corresponding assembly information and transmits it to the terminal device 20 in the manner described, where it can be displayed to the user via the display 22.

[0047] The assembly information includes at least the assembly position of component 10, so that the user can easily see where component 10 is to be added to the already installed components 14. The information can be presented in various ways, but a three-dimensional representation, in particular an exploded view as shown in Fig. 2 has proven particularly effective.

[0048] Fig. Figure 2 shows one of almost endless possibilities for graphically displaying assembly information, for example on a smartphone display. For example, if the user has the... Fig. If the identification code of component 12 (not shown) is scanned, for example, component 12 can be highlighted in the graphical representation, for example, by color-coding it in contrast to other components 16, by making it flash, etc. Components such as the two connecting elements 30 shown in the example, with which component 12 is directly connected, can be highlighted in a similar way. For example, it can be provided that in the graphical representation the connecting elements 30 are colored yellow and component 12 is colored red, while other components 16, of which only some have been provided with reference numerals here, are simply shown in black and white. Here, the invention advantageously allows the person skilled in the art to choose a representation that is optimal for the respective application.Beyond the purely graphical representation of the component and its mounting position, assembly information can also be output acoustically, for example in the form of spoken instructions on how to connect the component 12 with the connecting elements 30.

[0049] A representation like the one in Fig. The two examples shown can be selected by the user, for example, by touching the display 22 ( Fig. 1) if it is a touch display, which will usually be the case, it can be rotated and enlarged or reduced so that the mounting position becomes particularly clear.

[0050] In addition to the position information, further assembly information can be displayed on the screen 22. This can include detailed assembly instructions, information on required tools, or warnings regarding potential hazards when handling the component 12.

[0051] It may be possible for the user, after successfully assembling a component, to confirm the assembly via an input function on the mobile device 20, so that the assembly progress can be tracked and, for example, saved. This can be helpful if the assembly process is interrupted and needs to be resumed at a later time. The data processing unit 24 can then update the digital blueprint and adjust the displayed assembly information accordingly.

[0052] To further improve the accuracy and efficiency of the assembly process, the system can be equipped with an AI-supported learning and optimization module. This module collects and analyzes data from past and ongoing assembly processes to continuously optimize the sequence of assembly steps and the presentation of assembly instructions. Such an AI-supported learning and optimization module can be implemented as a neural network that continuously analyzes data from completed assembly processes. It takes into account factors such as the time required for individual assembly steps, frequently occurring errors or difficulties, and user feedback.Based on this data, the module can optimize the sequence of assembly steps by, for example, breaking down more complex steps into smaller, easier-to-understand sub-steps or adjusting the arrangement of the steps so that frequently used tools or materials are used more efficiently.

[0053] Furthermore, the module can personalize the presentation of assembly instructions. For example, it can recognize whether a user is a beginner or experienced and adjust the level of detail in the instructions accordingly. For frequently occurring problems, the system can proactively suggest additional assistance or alternative solutions. The learning and optimization module can also recognize patterns in the assembly processes of different structures and apply these insights to new, similar projects, leading to continuous improvement of assembly instructions across various product lines.

[0054] Finally, the mobile device 20 can also be used for quality control. After assembly is complete, the user can use the device's camera to capture the finished structure 18 and send the image to the data processing unit 26 as described. There, it is compared with the target state (the target structure) according to the digital blueprint to ensure that all components have been assembled correctly. Alternatively or additionally to such a final quality control check, an initial completeness check can also be performed. In this check, the user first records the identification codes of all existing components, so that it can be automatically verified whether all components required for a specific structure are present. If certain components are missing, an automatic reordering process can also be triggered.

[0055] The system may be designed to initiate a multi-stage feedback process after the structure is completed, which could proceed as follows: First, the user is prompted to perform a final visual inspection and confirm the result via the user interface. The user can also enter specific comments on individual assembly steps or on the overall experience.

[0056] In a second step, the system can ask a series of targeted questions, such as about the clarity of the instructions, the user-friendliness of the application, or potential suggestions for improvement. These questions can be generated dynamically based on the specific assembly process and the difficulties identified. Additionally, the system can ask the user to photograph and upload certain aspects of the finished structure to allow for visual verification.

[0057] The collected feedback is then analyzed by the system and incorporated into the continuous improvement of the assembly instructions and the entire process. This can lead to adjustments in future versions of the digital blueprint, refinements to the user interface, or even suggestions for design changes to the physical components.

[0058] This comprehensive digital support not only makes the assembly process more efficient and error-resistant, but also significantly simplifies it for the user.

[0059] Within the scope of the invention, numerous modifications and further developments are possible, relating, for example, to the design and sequence of steps in generating and displaying the assembly information. Due to the aforementioned high computing power of modern end devices, it may be possible, for example, for a user who has purchased certain components, custom-made for a structure they have designed, to connect only once to a database maintained by the component manufacturer and retrieve a corresponding digital blueprint, which is then stored in the end device 20, where the subsequent steps are then executed autonomously.

[0060] Especially with complex structures, it can be advantageous to create a particularly detailed and interactive assembly manual that guides the user step by step through the assembly process. The process could be as follows:

[0061] The system first analyzes the digital blueprint of the structure to be assembled. Based on this analysis, a logical sequence of assembly steps is generated. This sequence takes into account the optimal order in which the components should be joined.

[0062] The assembly steps are arranged in a predetermined sequence. This sequence takes into account factors such as structural integrity during assembly, the accessibility of the components, and the efficiency of the assembly process.

[0063] Detailed instructions are generated for each assembly step. These can include textual descriptions, visual representations (such as 3D models or exploded views), and specific instructions for handling the components.

[0064] The system also takes into account necessary preparatory or intermediate steps. These can include, for example, preparing tools, applying adhesive, or temporarily fixing parts. These steps are integrated into the assembly instructions at the relevant points.

[0065] During the assembly process, the instructions dynamically adapt to the progress. When the user completes and confirms a step, the system automatically updates the display to the next relevant step. If deviations or errors are detected, the system can suggest alternative steps or corrective actions.

[0066] The user interface offers intuitive navigation between assembly steps. Users can scroll forward and backward, jump to specific sections, or access an overview of all steps. This allows users to navigate flexibly through the instructions, for example, to review previous steps or preview later ones.

[0067] The generated assembly instructions are displayed on the display device, typically the screen of a mobile device. The display integrates the step-by-step instructions with the specific assembly information for the component currently being assembled. This can include a combination of text, images, 3D models, and interactive elements.

[0068] When the user enters the identification code of a component, the display automatically synchronizes with the corresponding assembly step. This ensures that the user always has the relevant information for the current component in front of them.

[0069] The system tracks the user's progress through the assembly steps. It can provide feedback on the percentage of assembly completed and estimates of the remaining time. Encouragement or tips can also be displayed as needed.

[0070] Once all assembly steps are completed, the system can offer a final checklist or verification process to ensure that all steps have been performed correctly.

[0071] Through this detailed and interactive approach, the invention offers comprehensive support throughout the entire assembly process. It combines the advantages of digital technology with a user-friendly interface to enable efficient and error-free assembly.

[0072] The solution according to the invention effectively addresses the aforementioned shortcomings of the prior art. In particular, it overcomes the limitations of paper-based two-dimensional representations, which often lead to confusion and errors. By providing three-dimensional representations, especially exploded views and color highlighting of the assembly positions, on a digital device, the user's spatial understanding is significantly improved. This reduces the likelihood of assembly errors and increases the efficiency of the entire process.

[0073] Furthermore, the invention solves the problem of the rigidity of printed instructions. The system can dynamically react to the progress of the assembly process and adapt the instructions accordingly. This enables flexible and user-friendly assembly support that can adapt to individual needs and unforeseen situations.

[0074] A particular advantage of the invention lies in the significant improvement of quality assurance during the assembly process. Unlike conventional methods, where defects are often only discovered after assembly is complete, the system according to the invention enables continuous quality control. This can be achieved in several ways:

[0075] Real-time verification: At every step of the assembly process, the system can check whether the correct component has been placed in the correct position. This is done by comparing the captured identification code with the digital blueprint.

[0076] Progress monitoring: The system can track the assembly progress and ensure that all steps are carried out in the correct order. Any deviations can result in an immediate notification.

[0077] Visual inspection: By being able to take a picture of the current structure after each assembly step and compare it with the target state, even subtle deviations can be detected early.

[0078] Final overall review: After completion of the structure, the system enables a comprehensive review by comparing the completed structure with the digital model.

[0079] This multi-stage quality control not only significantly reduces the likelihood of assembly errors, but also allows for rapid correction should any deviations occur. This saves time and costs that would otherwise be incurred for subsequent corrections.

[0080] Furthermore, the integration of AI-supported learning and optimization modules allows the system to continuously learn from past assembly processes and improve itself. This leads to a constant optimization of the assembly instructions and sequence, which further increases the efficiency and quality of the assembly process.

[0081] The invention offers a comprehensive solution to the challenges of modern assembly processes. It combines digital technology with practical applicability, creating a system that is not only user-friendly and efficient, but also enables unprecedented precision and quality assurance in assembly.
