Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless charging infrastructure is expanded to accommodate more vehicles, then charging capacity increases, but power overload risk increases
Solution Approach 1:
The control apparatus calculates the accommodatable number of wireless charging vehicles per unit section in advance by obtaining information on available power and estimated power consumption. This preliminary calculation prevents power overload by determining the maximum number of vehicles that can be charged simultaneously before allowing vehicles to enter charging sections.
Solution Approach 2:
The system continuously monitors available power and power consumption data, using this feedback to dynamically adjust the accommodatable number of vehicles. The control apparatus transmits control signals to vehicles based on real-time power status, ensuring the charging infrastructure operates within safe power limits while maximizing charging capacity.
2Productivity
If multiple vehicles are allowed to charge simultaneously in a unit section, then charging efficiency increases, but power consumption management becomes complex
Solution Approach 1:
The control apparatus manages power consumption by changing key parameters including the number of simultaneously charging vehicles, the unit section length, and power allocation per vehicle. By adjusting these parameters based on available power and estimated consumption, the system optimizes charging efficiency while keeping power management complexity manageable through standardized calculation methods.
3Device complexity
If the unit section length for wireless charging is increased, then fewer sections are needed, but the accommodatable number of vehicles per section decreases
Solution Approach 1:
The system dynamically determines the optimal unit section length based on available power and estimated power consumption per unit section. Rather than using a fixed section length, the control apparatus adjusts the unit section parameters to balance the number of sections needed against the charging capacity of each section, optimizing overall system productivity.
