Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If inductive charging systems are embedded in roadways to charge electric vehicles, then electric vehicles can be charged while traveling, but energy is wasted when lanes are unused and variable energy demands cannot be effectively managed
Solution Approach 1:
The patent implements dynamic lane activation where charging lanes can be switched between active and inactive states based on real-time demand. The system controller receives vehicle presence detection signals and dynamically activates only the necessary charging lanes, preventing energy waste in unused lanes while ensuring charging availability when needed.
Solution Approach 2:
The system changes operational parameters by adjusting power allocation to different lanes based on demand. When vehicle presence is detected, the controller modifies power distribution parameters to activate specific lanes and adjust their power levels, optimizing energy usage according to actual charging requirements.
2Adaptability or versatility
If multiple charging lanes are activated to meet variable energy demands, then more vehicles can be charged simultaneously, but energy is wasted when full capacity is not needed
Solution Approach 1:
The system dynamically adjusts power allocation parameters to each lane based on detected vehicle presence and charging demand. The controller modifies power levels in real-time, activating only the number of lanes and power levels necessary to meet current demand, thereby maintaining adaptability while preventing excess energy consumption.
Solution Approach 2:
The system implements feedback mechanisms where vehicle presence detection signals trigger controller responses. The controller continuously monitors lane usage and adjusts power allocation based on this feedback, ensuring that energy is allocated efficiently to match actual demand while maintaining the capability to respond to variable conditions.
3Reliability
If a fixed number of charging lanes are maintained active, then charging availability is ensured, but system complexity increases and energy efficiency decreases
Solution Approach 1:
The system uses dynamic lane activation controlled by a central controller that receives vehicle presence signals and automatically adjusts which lanes are active. This dynamic approach maintains charging availability when needed while reducing the number of actively managed lanes during low-demand periods, thereby reducing system complexity without sacrificing reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system optimizes energy use by activating or deactivating lanes and adjusting power levels according to demand, reducing waste and ensuring electric vehicles receive the necessary charge efficiently, while also encouraging vehicles to route for optimal charging opportunities.
Implementation Method 1
inductive charging systems may be imbedded in the ground (e.g., concrete or asphalt) below a parking spot in a garage or parking lot. Electricity flowing through the inductive charging system may inductively charge a battery in the electric vehicle.

AI summary
Embodiments include apparatus and methods for implementing lane charging for a roadway. A road segment in a geographic region is identified from a geographic database. The road segment may be identified based on the geographic position of a vehicle. A lane charging management device receives real time data related to the vehicle, the environment, or the electricity associated with the charging station. A lane charging command for a charging device associated with the road segment is generated in response to the real time data.
