Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the electrical energy storage system is designed with fixed capacity for vehicles without secondary propulsion, then the system provides sufficient energy storage, but the system dimensions and complexity increase significantly
Solution Approach 1:
The energy storage system is divided into separate modules (first energy storage module for auxiliary circuits, second energy storage module for propulsion) that can be independently configured. This segmentation allows the system to provide sufficient energy storage capacity when needed while avoiding excessive dimensions by only including necessary modules for each specific vehicle application.
Solution Approach 2:
The energy storage system is designed as a universal platform that can serve multiple functions and vehicle types. The modular architecture with optional second energy storage module allows the same basic system design to be adapted for vehicles with or without secondary propulsion needs, eliminating the requirement for completely new designs for different applications.
2Adaptability or versatility
If the electrical energy storage system is customized for each vehicle type, then the system optimizes energy storage for specific applications, but the design complexity and variety increase
Solution Approach 1:
The system uses segmented modular modules that can be selectively combined. The first energy storage module is always present for auxiliary circuits, while the second module for propulsion is added only when needed. This segmentation enables easy adaptation to different vehicle requirements without increasing overall design complexity, as the same modular components are reused across different configurations.
Solution Approach 2:
The system design is made dynamic and flexible through the optional second energy storage module. Rather than creating entirely different fixed designs for each vehicle type, the system allows dynamic configuration where the propulsion module can be added or removed based on specific vehicle needs, simplifying the overall design process while maintaining high adaptability.
3Power
If a larger energy storage system is installed to provide propulsion power, then the system can power both auxiliary circuits and propulsion, but the system size and cost increase
Solution Approach 1:
The power delivery system is segmented into two separate pathways: the first energy storage module dedicated to auxiliary circuits and the second energy storage module dedicated to propulsion. This segmentation allows the system to provide high power output capability when needed without requiring a single oversized system, as power is drawn from the appropriate module based on the specific demand, optimizing system size.
4Temperature
If the ventilation system is designed for both modules, then cooling is provided when both modules are present, but the system complexity increases for vehicles with only one module
Solution Approach 1:
The ventilation system is designed as a universal cooling solution that automatically adapts to the configured modules. The same ventilation infrastructure can cool both the first energy storage module and the second energy storage module when both are present, or only the first module when the second is absent. This universal design provides necessary cooling capability without increasing system complexity for different vehicle configurations.
