Vehicle Digital Twin Assembly Tracking for Flexible Modular Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle assembly plants face high costs and capital expenditures in setting up conveyor systems or adapting automatic guided vehicles (AGVs) for specific tasks, and struggle with manufacturing different product configurations within the same facility.
Innovation Solution
A method is introduced to create a digital twin for vehicles by scanning and updating digital files of modular vehicle subassemblies as they move through assembly zones, allowing for efficient tracking and assembly of components, and enabling the creation of a comprehensive digital representation of the vehicle's assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conveyor systems or automatic guided vehicles are implemented for vehicle assembly, then assembly line functionality is improved, but capital expenditure and investment costs increase significantly
Solution Approach 1:
The patent creates digital twins (virtual copies) of vehicle subassemblies and components that can be manipulated, tracked, and assembled in a virtual environment. This digital replication eliminates the need for expensive physical conveyor systems and AGVs, as the digital models can be moved and assembled through software interfaces without requiring costly physical infrastructure.
Solution Approach 2:
The invention replaces the mechanical conveyor systems and automatic guided vehicles with a digital information system. Instead of physically transporting components along assembly lines, the patent uses digital scanning, data storage, and virtual assembly processes to track and manage component assembly, substituting mechanical transportation infrastructure with information-based management.
2Manufacturing precision
If assembly infrastructure is customized for specific vehicle configurations, then manufacturing precision is improved, but adaptability to different product configurations decreases
Solution Approach 1:
The patent implements a dynamic digital twin system that can be reconfigured for different vehicle models and assemblies. The digital representations can be updated and modified to reflect different product configurations without requiring physical infrastructure changes. This allows the same facility to efficiently assemble multiple vehicle types by simply updating the digital models and assembly instructions.
Solution Approach 2:
The digital twin platform serves multiple functions: it tracks components, stores assembly instructions, manages quality control, and adapts to different vehicle configurations. This universal digital system replaces the need for specialized infrastructure for each vehicle type, allowing a single facility to handle diverse product configurations with the same physical equipment.

AI summary
A method for creating a digital twin for a vehicle assembled on at least one assembly line includes assembly of a modular vehicle subassembly (MVS) in a plurality of MVS assembly zones by assembling at least one component at each MVS assembly zone, scanning the at least one component at each MVS assembly zone and acquiring scanned data, and storing the scanned data in a MVS temporary digital file assigned to the pre-assembled MVS. The method also includes updating a MVS permanently digital file assigned to the pre-assembled MVS after the at least one component at each of the MVS assembly zones has been assembled and storing the MVS permanent digital file when assembly of the MVS is complete.
