Engineering Contradiction Analysis
1Object-affected harmful factors
If electric vehicles use batteries with limited energy storage capabilities, then the vehicles can operate without fuel and reduce pollution, but the traveling range is limited and recharging is required regularly
Solution Approach 1:
The system performs preliminary actions by proactively monitoring battery charge levels and automatically planning recharging routes before the battery is depleted. The power management apparatus continuously tracks energy consumption patterns and pre-identifies suitable recharging stations along the vehicle's intended path, ensuring the vehicle can reach charging infrastructure without range anxiety.
Solution Approach 2:
The system implements continuous feedback loops where the power management apparatus monitors real-time battery status, energy consumption rates, and vehicle operational conditions. This feedback information is used to dynamically adjust power distribution across vehicle systems and to update recharging route recommendations, creating a closed-loop control system that optimizes both range utilization and charging timing.
2Quantity of substance
If recharging stations are deployed sparsely, then infrastructure cost is reduced, but electric vehicles cannot operate on long distance trips without charging stations
Solution Approach 1:
The power management apparatus is designed as a universal system that can adapt to various charging infrastructure types and distributions. It integrates multiple recharging methods including wireless inductive charging, plug-in charging, and kinetic energy recovery systems. The route planning functionality works with any distribution of charging stations, making the vehicle capable of long-distance travel regardless of infrastructure density.
Solution Approach 2:
The system dynamically adjusts its operation based on real-time conditions including battery state of charge, vehicle location, destination, and available charging infrastructure. The route planning is not static but continuously updates based on changing conditions, allowing the vehicle to adapt its behavior to maximize range utilization and minimize the need for dense charging station deployment.
3Reliability
If the electrical power system or power grid fails, then power supply reliability is compromised, but electric vehicles still need access to recharging capabilities
Solution Approach 1:
The system extracts the vehicle from complete dependency on external power grid infrastructure by incorporating onboard energy management that can operate independently. The power management apparatus can manage the vehicle's battery systems autonomously, utilizing regenerative braking to capture kinetic energy and store it in the battery, thereby providing recharging capability even when external power infrastructure is unavailable or failed.
Solution Approach 2:
The system provides beforehand cushioning by maintaining reserve battery capacity and identifying alternative recharging options in advance. The power management apparatus monitors multiple potential recharging locations and keeps backup routes ready, ensuring the vehicle can access power even if primary charging infrastructure fails. This preparatory approach cushions against power system failures by having pre-planned contingencies.
