Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Most electric vehicles cannot be wirelessly charged while in use due to a lack of wireless charging equipment in the vehicles and roadways.
Innovation Solution
A system for wireless power transfer among multiple vehicles, which includes identifying vehicles needing charging, deploying wireless power chargers to those without capabilities, and charging them using a wireless power transfer module, allowing charging while the vehicles are in motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless charging equipment is installed in vehicles and roadways, then wireless charging capability is improved, but device complexity and infrastructure cost increase
Solution Approach 1:
Vehicles that have wireless charging capability charge other vehicles without external infrastructure. The charging system is self-contained within the vehicle group, with one vehicle acting as a mobile charging station for others, eliminating the need for roadway-installed equipment
Solution Approach 2:
Vehicles serve dual purposes: they are both powered units and charging units. The same vehicle that receives power can later provide power to others, making the charging capability universal across the vehicle group without requiring dedicated infrastructure
2Use of energy by moving object
If vehicles stop to be charged, then charging is performed, but productivity and travel time are reduced
Solution Approach 1:
Charging is performed continuously while vehicles are in motion through dynamic grouping. Vehicles can charge at any location without stopping, maintaining continuous travel and productivity while receiving power through wireless transfer between moving vehicles
3Adaptability or versatility
If wireless charging infrastructure is deployed on roadways, then wireless charging is enabled, but manufacturing cost and complexity increase
Solution Approach 1:
Vehicles act as intermediaries to transfer power between each other, eliminating the need for roadway infrastructure. Instead of installing charging equipment in the environment, the charging function is mediated through the vehicles themselves, which can deploy and move freely without fixed installation
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

Data Source
AI summary
Computer-implemented methods for wireless power transfer among multiple vehicles are provided. Aspects include identifying a group of vehicles, from a plurality of vehicles, that require charging and identifying a wireless charging capability of each vehicle of the group of vehicles. Aspects also include deploying wireless power chargers to the vehicles of the group of vehicles that do not have wireless charging capability and charging each vehicle of the group of vehicles using a wireless power transfer module. The charging of the group of vehicles is performed while the vehicles are in motion.
