Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for monitoring and maintaining passenger transport systems, such as elevators and escalators, face inefficiencies due to the need for frequent on-site inspections and complex data management, especially when components are replaced, leading to inaccuracies in digital twin data sets.
Innovation Solution
A method for replacing components in passenger transport systems involves updating the digital double data set with component data from the new part, structured into modular components, allowing for automated and accurate tracking of physical properties, reducing the need for extensive data processing and storage resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detailed physical properties of all components are recorded and stored in a digital double data set, then monitoring accuracy is improved, but storage resources and data processing requirements increase
Solution Approach 1:
The digital double data set is segmented into individual component data set modules, each representing a specific component. This modular structure allows selective storage and processing of only relevant component data, reducing overall storage requirements while maintaining monitoring accuracy for critical components.
Solution Approach 2:
Essential physical properties are extracted and stored in standardized component data structures, separating critical monitoring parameters from comprehensive component specifications. This extraction focuses storage resources on the most important properties that affect system monitoring and maintenance decisions.
2Measurement precision
If component data is manually updated in the digital double data set, then data accuracy is improved, but time consumption and labor resources increase
Solution Approach 1:
The system enables automated self-updating of the digital double data set through direct data transfer from replacement components. The component data set modules automatically update themselves by receiving data from the actual replacement component, eliminating manual data entry while ensuring data accuracy through direct source verification.
Solution Approach 2:
Component data is prepared and validated in advance during the component replacement process. The replacement component's data is read and verified before being transferred to the digital double data set, ensuring accuracy is established proactively rather than through post-installation manual verification.
3Stability of the object's composition
If complete component data sets are replaced individually, then data consistency is improved, but data processing complexity increases
Solution Approach 1:
The data set is divided into standardized, self-contained component data set modules. Each module represents a complete component definition with all necessary physical properties and parameters. This segmentation enables consistent replacement of individual modules without affecting other components, maintaining data consistency while simplifying processing through modular operations.
