Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional analytic and control algorithms are developed and deployed in building management systems, then the system can process building data, but the development and deployment process becomes time-consuming and requires significant software development effort
Solution Approach 1:
The patent creates digital twins as virtual copies of physical building equipment and spaces. These digital twins replicate the behavior and characteristics of actual building components, allowing analytics to be performed on the digital replicas rather than requiring complex algorithms to be developed for each physical system. This copying approach eliminates time-consuming algorithm development while maintaining accurate data processing capabilities.
Solution Approach 2:
The patent introduces digital twins as an intermediary layer between physical building equipment and analysis systems. Instead of directly developing algorithms for physical equipment, the system uses digital twins as mediators that capture and represent equipment behavior, thereby reducing software development effort while preserving data processing effectiveness.
2Adaptability or versatility
If traditional analytic and control algorithms are used in building management systems, then data can be processed, but the algorithms lack flexibility to adapt to changing circumstances in the building
Solution Approach 1:
The patent implements dynamic digital twins that continuously update to reflect changing building conditions. Rather than using static algorithms that require complex modifications to adapt, the digital twins naturally evolve with the building equipment they represent, providing inherent flexibility without increasing algorithmic complexity. The digital twins can adapt to new scenarios through updates to their virtual models rather than requiring complex algorithmic changes.
3Loss of information
If building management systems generate detailed analytic output data, then comprehensive information is available, but the output data becomes hard for users to conceptualize and relate to physical building components
Solution Approach 1:
The patent uses digital twins as visual and functional copies of physical building components. Because digital twins replicate the appearance and behavior of actual equipment, users can easily associate analytic data with their physical counterparts. This copying approach maintains complete information while improving user comprehension through familiar visual representations that directly correspond to physical building components.
