Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed connections of rectifier circuits are used, then device complexity is reduced, but output power decreases when input power changes
Solution Approach 1:
The patent applies dynamics by transforming the fixed connection configuration into a dynamic switching system. Multiple switches (first switches, second switches, and third switches) are introduced to enable real-time reconfiguration of circuit connections between series and parallel modes, allowing the system to adapt to changing input power conditions and maintain optimal output power.
Solution Approach 2:
The patent segments the connection configuration into independently controllable units. Each rectifier circuit can be individually connected or disconnected through dedicated switches, and the connection lines are divided into first connection lines and second connection lines that can be independently controlled, enabling flexible reconfiguration without affecting the entire system.
2Adaptability or versatility
If switching circuits with multiple switches are added, then adaptability to input power changes is improved, but device complexity increases
Solution Approach 1:
The switching circuit is segmented into functionally distinct components: first switches for individual circuit connection control, second switches for alternative path control, and third switches for cross-connection control. This segmentation allows each switch type to have a specific function, simplifying the control logic despite the increased number of switches.
Solution Approach 2:
The system implements dynamic adaptability through coordinated switching actions. When input power changes are detected, the control section dynamically adjusts the state of multiple switches to reconfigure the circuit connections, enabling the system to respond to varying operating conditions while maintaining manageable complexity through systematic switch control.
3Productivity
If switches are added to enable flexible connections, then productivity is improved through optimized power output, but device complexity increases
Solution Approach 1:
The patent achieves optimized power output through dynamic switching control. The control section monitors input power conditions and dynamically reconfigures the circuit connections by controlling the on/off states of multiple switches, allowing the system to maintain high productivity across varying operating conditions by adapting to maximum power transfer requirements.
