Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If solar power generation is used to charge the vehicle during driving, then the vehicle can be charged without limitation due to driving route and with reduced cost, but the charging depends on weather conditions and the amount of power supply is not constant
Solution Approach 1:
The patent combines solar power generation with wireless charging road technology to create a hybrid charging system. The vehicle can switch between solar charging and wireless charging based on weather conditions and power availability, ensuring continuous and reliable power supply while maintaining charging convenience during driving.
Solution Approach 2:
The wireless charging road acts as an intermediary power source that supplements solar power generation. When solar power is insufficient due to weather conditions, the wireless charging road provides additional power to maintain stable charging, thus resolving the reliability issue while preserving the convenience of in-motion charging.
2Productivity
If wireless charging road is used to supply electric power to the vehicle during driving, then the vehicle can be charged during driving and power can be supplied through eco-friendly renewable energy sources, but the charging depends on charging infrastructure and limits driving route
Solution Approach 1:
The system dynamically switches between solar power generation and wireless charging road based on real-time conditions such as weather, power availability, and vehicle location. This dynamic adaptation allows the vehicle to maintain high charging efficiency while preserving driving route flexibility by using solar power when infrastructure is unavailable.
Solution Approach 2:
The vehicle is equipped with both solar power generation capability and wireless charging road compatibility, making it universally adaptable to different charging scenarios. This multi-functionality allows the vehicle to use either charging method depending on the situation, thus maintaining both charging efficiency and driving route flexibility.
3Ease of manufacture
If solar power generation and wireless charging road are independently applied to vehicles, then each technology can be implemented separately, but the utilization range of electric power is limited
Solution Approach 1:
The patent merges solar power generation and wireless charging road technologies into a unified charging management system. This integration allows the vehicle to utilize both power sources simultaneously or alternately, expanding the utilization range of electric power while maintaining the ease of implementing each technology separately through modular architecture.
