Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If charging facilities use a single source of energy (power grid) for power supply, then the system structure is simple, but the power supply efficiency is low and charging costs are high
Solution Approach 1:
The charging facility is designed to accept multiple energy sources (power grid, solar panels, wind turbines, thermal energy systems) and switch between them based on availability and cost. This multi-functional approach allows the system to maintain simple operation while achieving high power supply efficiency by selecting the most appropriate energy source for each charging scenario.
2Device complexity
If charging facilities use a single source of energy (power grid) for power supply, then the system structure is simple, but the charging costs are high
Solution Approach 1:
The system dynamically selects energy sources based on real-time conditions including electricity prices, weather conditions, and energy storage status. The control unit monitors cost parameters and automatically switches between power grid, solar, wind, and thermal energy sources to minimize charging costs while maintaining system structural simplicity.
3Loss of energy
If the power storage module stores both first electrical energy and second electrical energy, then the energy utilization is comprehensive, but the power storage capacity requirement increases
Solution Approach 1:
The power storage module pre-charges from renewable energy sources (solar, wind, thermal) when energy is available and costs are low, storing energy in advance for later use. This preliminary energy accumulation allows the system to utilize multiple energy sources comprehensively while reducing the need for excessive storage capacity, as energy is captured when conditions are favorable.
