Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single power source is used to supply electrical power, then the system is simple to operate, but the system cannot selectively choose the most cost-effective and efficient source of energy
Solution Approach 1:
The patent combines multiple power sources (grid, generator, photovoltaic array, battery) into a single integrated power distribution system. The controller merges these diverse sources and manages their coordination to provide seamless power supply, enabling selective choice of power sources while maintaining system coherence through centralized control.
Solution Approach 2:
The power distribution system is designed with multi-functionality to handle various power sources and operating conditions. The controller can universally manage grid power, generator power, renewable energy, and battery storage, adapting to different scenarios and selectively choosing the most efficient source based on cost and reliability criteria.
2Productivity
If multiple power sources are integrated, then the system can selectively choose the most cost-effective source, but the system complexity increases
Solution Approach 1:
The controller continuously monitors the status, cost, and reliability of each power source in real-time. This feedback mechanism enables the system to dynamically evaluate available power sources and automatically switch to the most cost-effective and efficient source, optimizing operational productivity while managing complexity through intelligent control.
Solution Approach 2:
The power distribution system is designed to be dynamic, allowing real-time adjustments in power source selection based on changing conditions. The controller can adaptively switch between power sources, adjust power flow distribution, and respond to varying operational requirements, enhancing productivity through flexible and responsive power management.
3Reliability
If the system continuously monitors power source costs and conditions, then the most efficient source can be selected, but the control system becomes more complex
Solution Approach 1:
The controller implements continuous monitoring of power source conditions, costs, and reliability metrics. This feedback loop provides real-time information about the status of each power source, enabling the system to make informed decisions about power source selection and switching, thereby ensuring reliable power supply while managing control complexity through systematic monitoring.
Solution Approach 2:
The power distribution system is designed to be self-managing, with the controller automatically monitoring power source conditions and making selection decisions without external intervention. The system self-adjusts power flow distribution and autonomously switches between sources based on monitored parameters, enhancing reliability while minimizing the need for complex external control mechanisms.
4Reliability
If the system isolates from the grid during instability, then power supply stability is maintained, but the system loses access to external power
Solution Approach 1:
The system proactively isolates from the grid when instability is detected, preventing potential power disruptions or damage. This preliminary protective action maintains power supply stability by disconnecting from unreliable external power sources while the system switches to alternative local power sources, ensuring continuous and stable operation.
Solution Approach 2:
The system prepares for grid instability by having alternative power sources ready and by implementing protective isolation mechanisms. Before grid instability can affect the system, the controller detects conditions and switches to backup power sources, cushioning the system against potential disruptions and maintaining stable power supply.
