Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single power reception device is used on the vehicle, then the system is simpler to manage, but the charging capacity and power distribution flexibility are limited
Solution Approach 1:
The vehicle is divided into multiple independent power reception devices (first power reception device and second power reception device), each capable of receiving power from the supply device independently. This segmentation allows the system to charge multiple devices simultaneously, increasing overall charging capacity while maintaining manageable complexity through modular design
Solution Approach 2:
The supply device is designed to provide universal power distribution capability to multiple different power reception devices on the same vehicle. The system can dynamically allocate power to different devices based on their needs, making the charging system more versatile and adaptable to various charging scenarios
2Productivity
If multiple power reception devices are provided on the vehicle, then charging capacity increases, but power distribution control becomes more complex
Solution Approach 1:
The system implements feedback control where the supply device receives information about the power needs and status of each power reception device, then adjusts power distribution accordingly. This feedback mechanism enables efficient power allocation to multiple devices while maintaining simple control through automated decision-making based on real-time system state
Solution Approach 2:
The system performs preliminary power distribution planning by determining in advance how much power each power reception device should receive. This preliminary action simplifies real-time control by pre-establishing power allocation strategies, allowing the system to efficiently manage multiple devices without complex moment-to-moment decision-making
3Power
If power is transferred to multiple devices simultaneously, then overall power reception increases, but risk of overcharging increases
Solution Approach 1:
The system uses feedback control to continuously monitor the charging status of each power reception device and adjust power input accordingly. This real-time feedback ensures that each device receives appropriate power levels and prevents overcharging, maintaining reliability while enabling simultaneous charging of multiple devices at optimized power levels
