Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If battery energy storage capacity is increased to extend driving range, then vehicle autonomy is improved, but vehicle weight and cost increase
Solution Approach 1:
The battery system is divided into multiple modular battery packs that can be independently managed and charged. Each battery pack has its own monitoring and control systems, allowing the vehicle to operate with partial battery capacity while reducing overall weight, and enabling flexible reconfiguration based on driving needs.
Solution Approach 2:
A power management system acts as an intermediary between multiple charging sources (grid charging, regenerative braking, wireless charging) and the battery packs. This system optimizes energy flow and charging strategies to extend driving range without requiring excessive battery capacity, thereby reducing weight.
2Reliability
If reliance on fixed charging stations is increased, then recharging reliability is improved, but adaptability to adverse conditions deteriorates
Solution Approach 1:
The power management system is designed to support multiple charging modes and energy sources, including grid charging, regenerative braking, wireless inductive charging, and mobile charging units. This multi-functional capability ensures reliable recharging regardless of whether fixed charging stations are available or operational.
Solution Approach 2:
The system dynamically adjusts charging strategies based on real-time conditions such as battery state of charge, vehicle location, grid availability, and environmental factors. This dynamic adaptation allows the system to maintain reliability while responding flexibly to adverse conditions like power grid failures or unavailable charging infrastructure.
3Productivity
If centralized power management system is implemented, then control efficiency is improved, but system complexity and communication requirements increase
Solution Approach 1:
The power management system is segmented into distributed control units located at each battery pack and a central management controller. Each control unit handles local monitoring and basic control functions, while the central controller coordinates overall system management. This segmentation maintains control efficiency while reducing communication bandwidth requirements and system complexity.
Solution Approach 2:
The system implements partial centralization where only critical functions require centralized control, while routine monitoring and basic control operations are handled locally at each battery pack. This approach achieves sufficient control efficiency without the full complexity of a completely centralized system.
