Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a battery module is used to power the controller and LED circuit for fault indication, then the fault unit can be accurately identified and positioned, but the device complexity increases due to the additional battery module and power management components
Solution Approach 1:
The battery module is designed to serve multiple functions: it provides power to the controller during normal operation, powers the LED circuit for fault indication, and can trigger positioning mode through its control module. This multi-functionality reduces the need for separate dedicated components, thereby managing device complexity while maintaining accurate fault identification capability
2Reliability
If the battery module continuously powers the LED circuit to indicate fault status, then the fault unit is always visible, but the energy consumption increases significantly
Solution Approach 1:
The LED circuit is activated periodically or on-demand rather than continuously. The control module receives control signals from a switch to trigger positioning mode, which activates the LED circuit only when needed for fault indication. This periodic activation maintains reliable fault indication capability while significantly reducing overall energy consumption compared to continuous operation
3Productivity
If the battery module is added to enable fault unit positioning without disrupting main power supply, then system availability is maintained, but the manufacturing cost increases
Solution Approach 1:
The battery module is integrated with the existing controller and LED circuit rather than being completely separate. The control module within the battery module communicates with the controller, and the LED circuit serves both normal operation and fault indication functions. This merging approach allows fault unit positioning capability to be added while maintaining system availability, while reducing manufacturing costs compared to completely separate systems
