Digital Twin Virtual Conformity Assessment for Passenger Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional conformity assessment of passenger transport systems, such as elevators and escalators, is time-consuming, costly, and lacks the ability to identify the root cause of deviations from design specifications, often requiring costly modifications and delays.
Innovation Solution
A method for conducting a partially virtualized conformity assessment using a digital doppelganger data set that simulates the physical properties and functionalities of the system, allowing for early detection of defects and reducing the need for physical testing by deriving values from this data set or through simulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional conformity assessment methods are used on fully installed passenger transport systems, then comprehensive verification of system requirements is achieved, but the process becomes time-consuming and costly with significant delays
Solution Approach 1:
The patent applies preliminary action by performing conformity assessment on a digital twin representation of the passenger transport system before physical installation. This allows verification of design compliance, functional requirements, and safety standards during the virtual modeling phase, enabling early detection and correction of deficiencies without delaying the physical implementation timeline
Solution Approach 2:
The patent creates and uses a digital twin (copy) of the passenger transport system that replicates its physical properties, geometry, and behavior. This virtual copy enables comprehensive conformity assessment through simulation and analysis without requiring the actual physical system to be installed and tested, significantly reducing assessment time while maintaining verification reliability
2Reliability
If conventional conformity assessment is performed after installation, then system compliance is verified, but root cause analysis of deficiencies becomes difficult and costly modifications are required
Solution Approach 1:
The digital twin enables preliminary conformity assessment before physical installation, allowing identification and correction of design and manufacturing deficiencies in the virtual phase. This preliminary verification includes tracing deficiencies to their root causes in the digital model, eliminating the need for complex post-installation diagnostic procedures and costly field modifications
Solution Approach 2:
The digital twin serves as a virtual replica that preserves complete design and manufacturing information. When deficiencies are detected during conformity assessment, the digital copy allows easy tracing back to the specific design decisions, manufacturing parameters, or assembly instructions that caused the issue, simplifying root cause analysis compared to physical system inspection
3Reliability
If physical components are manufactured and installed before conformity assessment, then the system can be physically tested, but errors detected late require costly rework and delays
Solution Approach 1:
The patent performs conformity assessment on the digital twin before physical manufacturing and installation of components. This preliminary verification ensures that the design and planned manufacturing parameters will produce a compliant system, allowing correction of any issues in the virtual phase and preventing costly rework after physical production has begun
Solution Approach 2:
The digital twin copy enables virtual prototyping and testing of the passenger transport system before physical manufacturing. By verifying conformity requirements on the virtual model, the patent ensures that when physical components are manufactured, they will meet all specifications on the first attempt, greatly improving manufacturing efficiency and reducing waste

AI summary
The invention relates to a method and a device for carrying out an at least partially virtualised conformity assessment for a passenger transport system (1). The conformity assessment is carried out following a specified checking protocol before the passenger transport system (1) is transferred to a user. The passenger transport system (1) was designed beforehand so as to have a large number of components (2), in a manner individualised for an intended purpose. A digital duplicate data set, which maps the passenger transport system (1) that is designed in an individualised manner, is created in which physical properties of components (2) of the passenger transport system (1) are rendered in a machine-processible manner. For the conformity assessment, it is checked whether properties of the passenger transport system (1) correspond to target specifications. When the conformity assessment is carried out, at least some of the properties of the passenger transport system (1) that are to be checked during the conformity assessment are determined as part of virtualised conformity assessment steps by deriving values from the digital duplicate data set or by simulations on the basis of the digital duplicate data set, and given as virtual values in a results report.
