Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If on-site technician intervention is used for equipment testing and commissioning, then equipment performance can be properly evaluated, but startup time is prolonged due to the need for physical presence at the building
Solution Approach 1:
The system enables automated self-testing of building equipment through the BMS. The processor automatically receives equipment data, identifies evaluation routines based on equipment parameters, executes testing routines, and generates performance evaluations without requiring external technician intervention. This self-service capability maintains measurement precision while eliminating the time loss associated with on-site technician presence.
Solution Approach 2:
The patent replaces the mechanical system of on-site technician physical presence with an automated electronic system. The BMS processor communicates with equipment through digital interfaces, automatically executing testing routines and analyzing results. This substitution eliminates the need for physical travel and on-site manual testing while maintaining comprehensive equipment evaluation capabilities.
2Loss of time
If remote automated testing is implemented, then startup time is reduced, but system complexity increases due to automated equipment discovery and model distribution across multiple communications busses
Solution Approach 1:
The BMS processor is designed with multi-functionality to handle diverse equipment types across multiple communications busses. It can automatically discover equipment, identify appropriate evaluation routines based on equipment parameters, execute tests, and generate reports. This universal capability, while increasing apparent complexity, actually streamlines the overall process by eliminating the need for separate manual procedures for different equipment types.
Solution Approach 2:
The system performs preliminary actions by maintaining a database of equipment models and evaluation routines beforehand. When new equipment is added, the processor automatically discovers it, matches it with the appropriate model from the database, and selects the correct testing routine. This preliminary preparation of equipment models and routines reduces the complexity of real-time decision-making and accelerates the commissioning process.
3Productivity
If automated equipment discovery and model distribution are implemented across multiple communications busses, then integration speed improves, but the extent of automation increases system complexity
Solution Approach 1:
The system employs feedback mechanisms where the processor continuously monitors communications busses for new equipment, receives equipment data, and automatically adjusts the testing process based on equipment responses. The processor evaluates equipment parameters, selects appropriate routines, executes tests, and uses the results to generate performance evaluations. This feedback loop enables high-speed automated integration while maintaining control and reducing the effective complexity through systematic decision-making.
