Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate repeater hardware is installed to amplify signals on the network, then signal strength is maintained across the network, but installation complexity and labor costs increase
Solution Approach 1:
The patent combines the repeater functionality with the building automation controller into a single integrated device. The controller includes both the control processing functions and the signal amplification/repeating functions in one unit, eliminating the need for separate repeater hardware installations while maintaining signal strength across the network.
Solution Approach 2:
The building automation controller is designed to perform multiple functions: it controls building equipment through the sensor actuator bus and simultaneously amplifies network signals through its network interface. This multi-functional design eliminates the need for dedicated repeater devices while maintaining network signal integrity.
2Reliability
If separate repeater hardware and power supplies are installed, then signal amplification is achieved, but installation time and costs increase
Solution Approach 1:
The patent merges the repeater unit and power supply into the building automation controller. The controller's existing power supply unit provides power to both the control functions and the network signal amplification functions, eliminating the need for separate power supply installations and reducing overall installation time.
Solution Approach 2:
The controller's power supply unit is designed to provide power to multiple components including the control processing unit and the network interface unit that performs signal amplification. This universal power supply design eliminates the need for separate power supplies while maintaining signal amplification capabilities.
3Length of stationary object
If separate repeater hardware is installed, then network coverage is extended, but device quantity and cost increase
Solution Approach 1:
The building automation controller is designed to perform dual functions: controlling building equipment and extending network coverage through signal amplification. By making the controller multi-functional, the patent eliminates the need for additional repeater devices while maintaining extended network coverage capability.
