Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If current electric vehicle battery charging systems are used, then vehicles can be recharged from stationary power sources, but frequent stops are required which limits travel distance and increases reliance on fossil fuel systems
Solution Approach 1:
The patent implements continuous wireless power transmission to the vehicle battery through electromagnetic fields, eliminating the need for periodic stops at charging stations. The power transfer occurs continuously during vehicle operation, maintaining uninterrupted energy supply and extending effective travel distance without time loss from recharging stops.
Solution Approach 2:
The patent replaces the mechanical connection system (physical charging ports and cables) with a wireless electromagnetic field-based power transmission system. This substitution eliminates the need for physical contact during charging, allowing continuous power transfer while the vehicle is in motion, thereby removing the constraint of frequent stops.
2Duration of action of moving object
If wireless RF charging system is implemented, then travel distance is extended without stopping for recharge, but system complexity increases
Solution Approach 1:
The patent integrates the wireless RF charging system with existing vehicle electrical components and battery management systems, allowing the same electromagnetic field infrastructure to serve multiple functions including power transmission, communication, and battery monitoring. This multi-functionality reduces overall system complexity despite adding wireless charging capabilities.
Solution Approach 2:
The system incorporates automatic power adjustment and regulation mechanisms that self-regulate based on battery charge state and vehicle power requirements, eliminating the need for complex external control systems. The battery management system automatically modulates power reception, simplifying the overall control architecture.
3Object-generated harmful factors
If wireless RF charging is used, then fossil fuel dependency is reduced, but energy efficiency requirements increase
Solution Approach 1:
The patent dynamically adjusts electromagnetic field frequency, power transmission levels, and receiver efficiency parameters to optimize energy transfer. By continuously monitoring and adjusting these parameters based on vehicle needs and environmental conditions, the system maximizes energy efficiency while maintaining the benefit of reduced fossil fuel dependency.
