Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional single charge port design is used, then device complexity is reduced, but charging time increases and productivity decreases
Solution Approach 1:
The charging system is segmented into two independent charge ports (first charge port and second charge port), each capable of independently charging different power sources. This allows parallel charging operations, reducing total charging time from T to approximately T/2 when both ports are utilized simultaneously.
Solution Approach 2:
The vehicle system is designed with multi-functionality to accept different charging standards at different ports (e.g., J1772 at first port, CHAdeMO or Type 2 at second port). This universal design enables flexibility in charging infrastructure utilization while maintaining reduced charging time through parallel operation.
2Adaptability or versatility
If traditional power management systems are used, then device complexity is minimized, but power distribution efficiency and adaptability deteriorate
Solution Approach 1:
The power management system dynamically switches between different power sources (first power source, second power source, or combination) based on availability, vehicle needs, and charging status. The system can transition from single-power-source mode to dual-power-source mode, adapting to various operational scenarios and improving overall versatility.
Solution Approach 2:
A controller acts as an intermediary between multiple power sources and the vehicle's electrical systems. This controller manages power distribution, coordinates charging operations, and ensures safe integration of different power sources, enabling adaptability without excessive complexity through centralized intelligent management.
3Use of energy by moving object
If single power source configuration is used, then device complexity is reduced, but energy availability and operational duration are limited
Solution Approach 1:
The system merges two independent power sources (first power source and second power source) into a unified power architecture. These power sources can operate independently or in combination, providing increased energy availability for extended range or higher power demands while maintaining manageable complexity through modular integration.
Solution Approach 2:
The second power source is pre-configured in the vehicle, ready for immediate use or rapid integration. This preliminary preparation ensures that when additional energy is needed, the system can quickly activate the second power source without complex real-time configuration, thereby increasing energy availability efficiently.

AI summary
Systems of an electrical vehicle and the operations thereof are provided. More particularly, a vehicle including a first charging port at a first location on the vehicle and a second charging port at a second location on the vehicle is provided. The first charging port of the vehicle may be different from the second charging port of the vehicle. That is, a standard associated with a receptacle of the first charging port may be different from a standard associated with a receptacle of the second charging port.
