Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inductors for phase adjustment are always connected in existing power generating devices, then power factor adjustment is maintained, but device complexity and maintenance needs increase
Solution Approach 1:
The patent applies the dynamics principle by making the connection state of phase adjustment inductors variable rather than fixed. Switches are introduced to dynamically connect or disconnect the inductors based on operating conditions, specifically connecting them when power generation decreases and disconnecting when power generation increases. This dynamic configuration maintains power factor adjustment capability when needed while reducing device complexity and maintenance needs during normal operation.
2Reliability
If inductors for phase adjustment are always connected, then power factor is optimized, but efficiency decreases during low power generation
Solution Approach 1:
The patent uses dynamics to adapt the phase adjustment inductor configuration to varying power generation levels. During low power generation, the inductors are connected to optimize power factor. During high power generation, the inductors are disconnected to avoid efficiency losses. This dynamic switching resolves the contradiction by optimizing power factor only when necessary.
3Reliability
If inductors for phase adjustment are always connected, then power factor adjustment is available, but installation becomes more complex
Solution Approach 1:
The patent applies dynamics by implementing a switched configuration for phase adjustment inductors rather than permanent connections. The inductors are installed but remain disconnected during normal operation, and are connected only when power generation decreases. This approach maintains power factor adjustment availability while simplifying installation compared to permanently connected configurations.
