Solution Overview

Problem

When a user vehicle runs out of electricity, it cannot move, leading to potential negative impacts on the user's subsequent schedule.

Innovation Solution

An information processing method that includes receiving a charging request from a user terminal, determining an operation plan for a power supply vehicle to transport the user and their vehicle to a destination while supplying power, and transmitting this plan to an operator terminal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the user vehicle waits for charging completion before moving, then the vehicle can reach the destination, but the user's schedule is delayed and negative effects occur

Engineering Contradiction:

Improvevehicle mobilityVSAvoiduser schedule delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by proactively detecting low battery states before complete power depletion occurs. The notification system alerts users in advance, allowing them to arrange alternative transportation or charging solutions before the vehicle becomes completely immobile, thus preventing schedule delays while ensuring vehicle reliability is maintained.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements continuous feedback by monitoring battery levels in real-time and providing ongoing notifications to users. This feedback loop allows users to understand the vehicle's power status and take appropriate actions (such as finding charging stations or arranging alternative transport) before the vehicle completely runs out of power, resolving the contradiction between maintaining mobility and avoiding schedule delays.

Inventive Principle:

Principle #23Feedback

2Loss of time

If the vehicle operates with low electricity, then the user can continue moving, but the vehicle may fail to reach the destination due to complete power depletion

Engineering Contradiction:

Improveuser schedule maintenanceVSAvoiddestination arrival guarantee

Core Design Contradiction:

Loss of timeVSReliability

Solution Approach 1:

The system takes preliminary action by detecting low battery conditions before complete power depletion and issuing advance notifications. This allows users to plan alternative arrangements (such as finding charging stations or arranging tow services) before the vehicle becomes completely inoperable, ensuring both continuous movement and reliable destination arrival.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides a cushioning effect by creating a buffer period between battery depletion and complete power failure through early detection and notification mechanisms. This buffer allows users to take corrective actions while the vehicle still has some power, preventing complete failure while maintaining the ability to reach the destination.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

An information processing method performed by an information processing apparatus includes receiving a request for charging that includes information indicating a destination from a user terminal, determining an operation plan of a power supply vehicle that includes transporting a user and a user vehicle toward the destination with supplying power to the user vehicle in response to the request for charging, and transmitting the operation plan to an operator terminal.
