Solution Overview

Problem

Electric vehicles require large batteries for extended driving ranges, which are expensive and add significant weight, reducing efficiency and increasing manufacturing costs.

Innovation Solution

A mobile charging system that allows electric vehicles to charge their batteries while in motion, using a mobile charge vehicle with an articulating arm and charge interface to transfer energy from a mobile charge vehicle to the electric vehicle, enabling smaller, lighter batteries and reducing the need for larger capacity batteries.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If large batteries are used to ensure adequate driving range, then driving range is improved, but vehicle weight increases and manufacturing cost increases

Engineering Contradiction:
Improvedriving rangeVSAvoidvehicle weight
Core Design Contradiction:
Duration of action of moving objectVSWeight of moving object

Solution Approach 1:

The mobile charge vehicle approaches and positions itself alongside the electric vehicle before charging begins, with the articulating arm ready to engage the charge interface. This preliminary positioning enables charging to start immediately when the EV needs power, rather than requiring the vehicle to stop at a fixed charging station, effectively extending the usable driving range without needing a larger battery.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The mobile charge vehicle acts as an intermediary energy source between the electric vehicle and the ultimate power supply. Instead of the EV carrying a large battery or stopping at fixed infrastructure, the mobile charger provides energy transfer on demand, allowing the battery to remain smaller while maintaining adequate driving range through periodic top-ups.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Duration of action of moving object

If large batteries are used to ensure adequate driving range, then driving range is improved, but manufacturing cost increases

Engineering Contradiction:
Improvedriving rangeVSAvoidmanufacturing cost
Core Design Contradiction:
Duration of action of moving objectVSEase of manufacture

Solution Approach 1:

The mobile charge vehicle is pre-positioned and ready to charge the electric vehicle before the battery becomes depleted. This allows the EV to maintain adequate driving range with a smaller, less expensive battery by receiving periodic charges on the road, eliminating the need to manufacture and install large, costly high-capacity batteries.

Inventive Principle:
Principle #10Preliminary action

3Use of energy by moving object

If the electric vehicle stops to charge at a fixed station, then the battery is recharged, but loss of time occurs and productivity decreases

Engineering Contradiction:
Improvebattery chargingVSAvoidcharging time
Core Design Contradiction:
Use of energy by moving objectVSLoss of time

Solution Approach 1:

The charging system transitions from a static fixed charging station to a dynamic mobile charge vehicle that moves alongside the electric vehicle. This allows charging to occur while the EV remains in motion or with minimal disruption to its travel schedule, significantly reducing the time loss associated with stopping at fixed charging infrastructure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mobile charge vehicle enables continuous or near-continuous charging operation by approaching and charging the EV during its normal operation. Rather than interrupting the vehicle's useful action (transportation) with lengthy charging stops, the system maintains continuous movement while transferring energy, keeping productivity high.

Inventive Principle:
Principle #20Continuity of useful action

4Productivity

If a mobile charge vehicle approaches and engages the charge interface while the electric vehicle is moving, then charging occurs without stopping, but the complexity of the charge interface engagement system increases

Engineering Contradiction:
Improvecharging efficiencyVSAvoidcharge interface engagement system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The articulating arm provides dynamic positioning capability that automatically adjusts to maintain proper engagement between the charge interfaces during vehicle movement. This dynamic adjustment mechanism handles the complexity of alignment and connection while enabling charging to occur during motion, maintaining high productivity without requiring overly complex manual intervention systems.

Inventive Principle:
Principle #15Dynamics
