Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data exchange between BIM and DT instances is performed manually, then flexibility in handling different data formats is maintained, but labor intensity and error rate increase significantly
Solution Approach 1:
The patent introduces an information modelling unit as an intermediary component that mediates between BIM and DT systems. This unit provides standardized modelling data that both systems can use, enabling automated data exchange while maintaining compatibility with different data formats. The intermediary translates and harmonizes data representations, eliminating the need for manual intervention while preserving format flexibility.
Solution Approach 2:
The information modelling unit serves multiple functions: it extracts data from BIM instances, converts it to standardized formats, and provides it to DT instances. This multi-functional component handles various data types and formats universally, replacing manual operations with a single automated system that maintains flexibility across different scenarios.
2Adaptability or versatility
If different software applications are used for BIM and DT, then specialized functionality is preserved, but interoperability and information exchange become labor-intensive and error-prone
Solution Approach 1:
The information modelling unit acts as a mediator between specialized BIM and DT software applications. It provides a standardized interface and common data representation that both specialized systems can utilize, enabling reliable automated information exchange while preserving the specialized functionality of each application through standardized data contracts.
3Productivity
If automated data conversion is implemented between BIM and DT systems, then productivity and accuracy improve, but system complexity increases
Solution Approach 1:
The automated conversion system is segmented into distinct functional components: the information modelling unit for data extraction and standardization, converter engines for format transformation, and composers for data assembly. This segmentation modularizes the complexity, making the system more manageable and maintainable while achieving high productivity and accuracy in data exchange.
4Device complexity
If manual handling of BIM and DT data is performed, then system complexity remains low, but error rate and time consumption increase
Solution Approach 1:
The system implements self-service automation where the information modelling unit automatically extracts, converts, and exchanges data between BIM and DT instances without human intervention. The converter engines autonomously handle format transformations, and composers automatically assemble data, eliminating manual handling time while keeping the added complexity manageable through modular design.
