Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple power generation systems are produced in parallel with unique vehicle designs, then each power generation can be optimized for its specific function, but production costs increase and overall efficiency decreases
Solution Approach 1:
The vehicle is designed with a universal platform that can accommodate multiple power generation types (battery electric, hydrogen fuel cell, hybrid) through a common chassis, electric drive train, and control system architecture. This allows the same vehicle platform to perform multiple functions with different power sources, reducing production costs while maintaining optimization for each power type through modular component selection
2Ease of manufacture
If vehicle operators use fixed power generation configurations, then vehicle design and production is simplified, but flexibility to adapt to changing fuel costs and availability is lost
Solution Approach 1:
The vehicle incorporates a dynamic power selection system with a controller that can automatically or manually switch between different power generation modes (battery, fuel cell, hybrid) based on real-time conditions such as fuel availability, cost signals, and operational requirements. This dynamic capability allows operators to adapt to changing conditions while maintaining a standardized vehicle platform for simplified production
3Adaptability or versatility
If hybrid vehicles incorporate multiple power generations, then some flexibility is achieved, but the vehicles still suffer from limitations of specific power generation configurations and do not allow easy switching
Solution Approach 1:
The vehicle employs a centralized controller as an intermediary that manages power flow and coordination between multiple power generation systems (battery pack, fuel cell stack, electric motors). This controller enables seamless switching and coordination between different power sources, making the complex hybrid system easy to operate automatically without requiring driver intervention or knowledge of system complexities
