Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicles are designed with different power generations in parallel, then the ability to adapt to changing fuel costs and availability is improved, but the production complexity and cost increase
Solution Approach 1:
The vehicle is designed with a universal interface that can accommodate multiple power generation modules (battery pack, fuel cell, thermal generator). The interface includes standardized electrical connectors and a controller that can adapt energy from different sources, allowing a single vehicle platform to perform multiple functions with different power generations without requiring separate vehicle designs for each power type.
Solution Approach 2:
The power generation system is segmented into separate, interchangeable modules that can be independently selected and installed. Each power generation type (battery, fuel cell, thermal generator) is provided as a distinct module that connects to the vehicle through a standardized interface, allowing flexible configuration and simplifying production by separating the power generation function from the vehicle platform.
2Adaptability or versatility
If vehicles are designed with different power generations in parallel, then the flexibility to switch between power sources is improved, but the manufacturing cost increases
Solution Approach 1:
A single vehicle platform with a universal interface design can produce multiple power generation variants. The standardized interface includes electrical connectors and a controller that work with any power generation module type, allowing manufacturers to produce one base vehicle model and offer different power generation options without creating entirely separate vehicle lines, thereby reducing tooling and production setup costs.
Solution Approach 2:
The vehicle is equipped with a pre-designed universal interface and controller system that is prepared in advance to accept different power generation modules. This preliminary configuration of the interface and control architecture during the base vehicle production simplifies subsequent module installation and reduces the need for additional manufacturing steps when switching between power generation types.
3Adaptability or versatility
If hybrid vehicles incorporate multiple power generations, then the limitations of specific power generation configurations are reduced, but the ability to easily switch between different power generations based on changing circumstances remains limited
Solution Approach 1:
The controller is designed to dynamically adapt to different power generation module configurations. The system can detect the type of power generation module installed and automatically adjust its operation to optimize performance. This dynamic adaptability allows easy switching between different power generations based on changing circumstances without requiring complex manual reconfiguration or multiple dedicated systems.
