Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of widespread electric vehicle-charging infrastructure limits the travel distance of electric vehicles, and available charging stations are often inconveniently located, making it difficult for vehicles to recharge before battery depletion.
Innovation Solution
A vehicle-to-vehicle charge transfer system that uses a charging cable and a donation control unit to transfer electric charge from one electric vehicle to another, enabling charging without the need for an external charging station, with secure and commercial models to support power exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electric vehicles rely on fixed charging stations, then charging infrastructure can be standardized, but the travel range is limited and charging convenience deteriorates due to sparse distribution
Solution Approach 1:
The patent enables electric vehicles to charge themselves by transferring energy from other vehicles directly, eliminating the need to travel to fixed charging stations. The donating vehicle serves as a mobile charging source, allowing the receiving vehicle to recharge at any location where another vehicle is available, thus dramatically improving charging convenience while maintaining reliability through peer-to-peer energy transfer
Solution Approach 2:
The patent transforms the charging paradigm from a stationary, location-based system to a mobile, vehicle-based system. By enabling energy transfer between moving vehicles rather than from fixed ground-based stations, the system adds the dimension of mobility to charging infrastructure, allowing charging to occur anywhere on the road rather than only at predetermined locations
2Ease of operation
If charging stations are distributed widely, then charging convenience improves, but infrastructure complexity and cost increase
Solution Approach 1:
The patent makes existing electric vehicles serve multiple functions: they are both propulsion vehicles and mobile charging stations. The same battery and power transfer equipment used for vehicle operation can also provide charging services to other vehicles, eliminating the need for separate, dedicated charging infrastructure and reducing overall system complexity
Solution Approach 2:
The patent uses the charging cable and control unit as intermediaries to transfer energy between vehicles. Rather than requiring complex wireless power transfer or specialized charging equipment, the system employs simple, standardized electrical connection components that already exist in the automotive industry, minimizing infrastructure complexity
3Adaptability or versatility
If vehicle-to-vehicle charge transfer is enabled, then charging flexibility improves, but system complexity increases due to parameter negotiation and control requirements
Solution Approach 1:
The patent implements a feedback mechanism where the donating vehicle's control unit receives charge transfer parameters from the receiving vehicle, processes this information, and adjusts the power transfer accordingly. The system continuously monitors transfer status and communicates between vehicles to ensure safe and efficient charging, with the control unit making real-time decisions based on received parameters and system state
Solution Approach 2:
The patent enables dynamic adjustment of charge transfer parameters such as voltage, current, and power level based on the receiving vehicle's battery state and requirements. The control system modifies these parameters in real-time during the transfer process, allowing flexible adaptation to different charging scenarios while managing system complexity through standardized parameter negotiation protocols
