Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless charging is implemented using roadway embedded power coupling elements, then electric vehicles can be charged while traveling, but the infrastructure cost and deployment difficulty increase significantly
Solution Approach 1:
The patent enables vehicles to charge each other directly using onboard electricity storage devices, eliminating the need for external charging infrastructure. The vehicle with excess energy serves as a mobile charging station, allowing the system to be self-sufficient and remove dependence on complex roadway modifications or fixed charging stations.
Solution Approach 2:
The invention transforms the onboard electricity storage device into a multi-functional component that serves both as the vehicle's own power source and as a wireless power transmitter for other vehicles. This universal design allows any vehicle with sufficient charge to act as a charging source, eliminating the need for dedicated charging infrastructure.
2Use of energy by moving object
If electric vehicles use on-board rechargeable electricity storage, then they can be powered electrically, but the limited capacity requires frequent charging stops
Solution Approach 1:
The patent enables continuous energy transfer between vehicles during motion, allowing the receiving vehicle to top up its battery without stopping. This continuous charging process eliminates idle charging time and maintains the vehicle's mobility, as energy transfer occurs while both vehicles are traveling at normal speeds.
Solution Approach 2:
The system allows vehicles to perform preliminary charging by receiving energy from other vehicles before their battery reaches critical levels. This proactive energy top-up prevents the need for urgent charging stops and maintains optimal energy levels throughout the journey.
3Ease of operation
If wireless power transfer is implemented between vehicles, then charging can occur during motion, but communication and control complexity increases
Solution Approach 1:
The patent utilizes existing vehicle communication systems for dual purposes: both for normal vehicle operations and for coordinating wireless power transfer. This multi-functional use of communication channels avoids adding dedicated complex communication infrastructure, as the existing systems are repurposed to handle charging coordination.
Solution Approach 2:
The system implements feedback mechanisms where vehicles continuously exchange information about their energy status, position, and charging rate. This feedback enables automatic adjustment of power transfer parameters, maintains optimal coupling between vehicles, and ensures safe operation without requiring complex manual control systems.

Data Source
AI summary
The disclosure involves wireless electric power sharing between vehicles. A first vehicle sends a charging request, wherein the first vehicle is at least partially powered by a first on-board rechargeable electricity storage. The first vehicle receives a response to the charging request from a second vehicle which is at least partially powered by a second on-board rechargeable electricity storage, and a communication channel is established between the first and second vehicles. The first on-board rechargeable electricity storage is charged using energy stored in the second on-board rechargeable electricity storage and wirelessly transferred from the second vehicle to the first vehicle. The charging is controlled with information exchanged between the first and second vehicles over the communication channel.
