Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital twin applications in building technology often fail to efficiently and safely operate buildings due to insufficient data exchange and standardization across different domains, leading to inadequate monitoring, control, and maintenance of complex building systems.
Innovation Solution
A method that combines multiple domains within a single digital twin, utilizing sensors and control systems as data sources to process and provide data for efficient building operation, including monitoring, anomaly detection, and maintenance, by integrating data from various systems like access control, lighting, and air conditioning, and using algorithms to predict system behavior and identify malfunctions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital twins are used to represent building systems and exchange data, then system monitoring and prediction capabilities are improved, but data exchange efficiency and standardization across different domains remain insufficient
Solution Approach 1:
The patent merges multiple domain-specific digital twins (HVAC, lighting, access control, fire safety) into a single integrated digital twin representation of the building. This integration enables unified data exchange protocols and standardized communication interfaces across all building systems, resolving the contradiction by maintaining reliable domain-specific monitoring while achieving efficient cross-domain data exchange through the integrated platform
2Measurement precision
If domain-specific digital twins are used for monitoring individual systems, then system-specific insights are improved, but overall building operation efficiency deteriorates due to insufficient cross-domain data integration
Solution Approach 1:
The integrated digital twin implements cross-domain feedback mechanisms where insights from one building system (e.g., occupancy data from access control) automatically inform and optimize other systems (e.g., HVAC scheduling, lighting control). This feedback loop maintains precise system-specific monitoring while dramatically improving overall building operation efficiency through coordinated multi-system optimization
3Manufacturing precision
If multiple separate digital twins are created for different building domains, then domain-specific modeling accuracy is improved, but system complexity and data integration requirements increase
Solution Approach 1:
The patent segments the building management system into distinct domain modules (HVAC, lighting, access control, fire safety), each represented by its own digital twin with specialized modeling capabilities. This segmentation maintains high domain-specific accuracy while the modular architecture actually reduces overall system complexity by allowing independent development, validation, and maintenance of each domain model without affecting others
4Adaptability or versatility
If standardization of parameters is implemented across domains, then knowledge transfer between buildings is improved, but adaptability to specific building conditions deteriorates
Solution Approach 1:
The patent implements a hierarchical parameter system where standardized core parameters (temperature, humidity, occupancy, energy consumption) enable knowledge transfer across different buildings, while domain-specific extended parameters can be added or modified to capture building-specific conditions. This parameter flexibility allows the system to maintain adaptability to specific building conditions while achieving standardization benefits for knowledge transfer and comparability
