Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed building control network with predetermined components is used, then initial system setup is straightforward, but the building model becomes outdated and difficult to maintain as construction progresses and new components are introduced
Solution Approach 1:
The building control network transitions from a static, predetermined configuration to a dynamic system that automatically adapts as new components are introduced. Sensors continuously discover new components and automatically update the building model database, ensuring the model remains current without manual intervention throughout construction and operation phases.
Solution Approach 2:
The system performs self-updating through automatic component discovery and linking. When new sensors or components are introduced, they automatically register themselves with the building model database and establish appropriate linkages without requiring manual configuration, enabling the system to maintain itself autonomously.
2Loss of information
If manual updates to the building model are performed during construction, then comprehensive detail can be captured, but maintenance becomes more difficult and time-consuming due to multiple subcontractors and employees
Solution Approach 1:
The building control network automatically discovers new components and updates the building model database without human intervention. Each sensor and component self-registers and establishes linkages autonomously, eliminating the time-consuming manual update process while maintaining complete and accurate building information.
Solution Approach 2:
The system implements continuous feedback loops where sensors monitor the building environment and automatically report new components to the building model database. This feedback mechanism ensures the model remains synchronized with the actual building state without requiring manual verification or updates.
3Adaptability or versatility
If new components are introduced into an existing building control network, then system functionality is enhanced, but inefficiencies and incorrect linkages occur due to network complexity
Solution Approach 1:
The system dynamically adapts to new components through automatic discovery mechanisms. When new sensors or devices are introduced, the system automatically detects them, determines their appropriate linkages to building model elements, and integrates them seamlessly without disrupting existing operations or requiring manual reconfiguration.
Solution Approach 2:
The building model database serves as an intermediary layer between physical components and control functions. New components communicate through this standardized interface, which automatically manages linkages and relationships, simplifying integration regardless of network complexity.
