Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to open separable contacts, then the circuit breaker can be operated reliably, but the operator must be physically present at the device which is inconvenient when far away
Solution Approach 1:
An IoT module is introduced as an intermediary device that receives wireless signals from remote devices and triggers the shunt trip mechanism. This intermediary enables remote operation without requiring the operator to be physically present at the circuit breaker, while maintaining system reliability through the established shunt trip infrastructure.
Solution Approach 2:
The manual mechanical operation of the circuit breaker is replaced with an automated electrical triggering system. The shunt trip device, activated by the IoT module through electrical signals, substitutes for the manual mechanical handle operation, enabling remote and automated control of the separable contacts.
2Loss of time
If remote operation is implemented using IoT module and shunt trip device, then operator convenience is improved, but additional components are added to the system
Solution Approach 1:
The shunt trip device is pre-installed within the circuit breaker assembly, ready for activation. The IoT module is pre-configured with wireless communication capabilities and electrical connections to the shunt trip mechanism. This preliminary preparation allows immediate remote operation when needed, reducing the time required to implement remote control functionality.
Solution Approach 2:
The shunt trip device serves multiple functions: it can be triggered by traditional manual operation, automated protection relays, and now remote IoT commands. This multi-functionality allows the system to handle various operation scenarios with a single integrated mechanism, reducing the need for separate components for each operation mode.
