Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If BAS data is integrated with BIM using a BAS-BIM integrator, then the quality of graphical representation and ease of operation are improved, but the device complexity increases
Solution Approach 1:
The patent introduces a BAS-BIM integrator as an intermediary component that bridges the building automation system and the building information model. This integrator automatically maps BAS points to BIM objects, eliminating the need for manual graphics creation while managing the complexity of data integration behind the scenes. The integrator serves as a mediator that handles the complex coordination between BAS and BIM systems transparently to the user.
Solution Approach 2:
The system creates a unified graphical representation by copying and integrating data from both BAS and BIM sources into a single cohesive interface. The BAS-BIM viewer generates a unified model that combines operational data with visual representation, allowing users to interact with building equipment through the BIM interface without manually creating graphics, thus improving ease of operation.
2Manufacturing precision
If BAS points are manually mapped to BIM objects, then the integration precision is improved, but the loss of time increases
Solution Approach 1:
The system performs preliminary actions by automatically generating mappings between BAS points and BIM objects using the BAS-BIM integrator. The integrator pre-establishes the relationships between operational data points and their corresponding visual representations in the BIM model, so that when the BAS-BIM viewer generates the unified interface, the integration is already precise and ready for immediate use without manual intervention.
Solution Approach 2:
The BAS-BIM integrator operates autonomously to perform the mapping task, making the system self-service in handling the integration process. It automatically identifies and maps BAS points to appropriate BIM objects without requiring user intervention, thereby maintaining integration precision while eliminating the time loss associated with manual mapping.
3Adaptability or versatility
If a unified BAS-BIM interface is generated, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The BAS-BIM viewer serves multiple functions by generating a unified interface that combines both visual representation and operational control capabilities. This single interface can display BIM graphics, show BAS data points, enable user interaction with building equipment, and provide historical data visualization. The integrator and viewer together create a universal platform that adapts to various building automation needs without requiring separate systems for each function.
