Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional design and construction methods are used for electric vehicles, then manufacturing simplicity is maintained, but adaptability to new technologies and infrastructure is limited
Solution Approach 1:
The vehicle is divided into modular subsystems (powertrain, chassis, body, electrical systems) that can be independently designed, manufactured, and upgraded. This segmentation allows different modules to incorporate new technologies at different rates without requiring complete system redesign, thus improving adaptability while managing complexity through standardized interfaces.
Solution Approach 2:
The vehicle system is designed with dynamic adaptability features including programmable control systems that can update software to leverage new technologies, and modular components that can be swapped or upgraded. This allows the vehicle to evolve and adapt to new infrastructure and technologies over time without fundamental redesign.
2Ease of repair
If power sources are frequently replaced or degraded, then maintenance flexibility is improved, but system reliability may be compromised
Solution Approach 1:
The system monitors power source health parameters (temperature, voltage, current, state of charge) in real-time and predicts degradation patterns. Maintenance actions are scheduled in advance based on predicted failures rather than waiting for actual failures, allowing planned replacements during low-impact periods and ensuring reliability is maintained through proactive intervention.
Solution Approach 2:
The power management system continuously monitors power source performance and provides feedback to control algorithms. This feedback enables dynamic adjustment of operating parameters to optimize power source lifespan, and triggers alerts when degradation thresholds are approached, allowing maintenance to be performed before reliability is compromised.
