Solution Overview

Problem

Electric vehicle drivers face boredom during the longer charging times compared to gasoline vehicles, as existing solutions do not effectively utilize the waiting period.

Innovation Solution

An information processing device and method that acquires a vehicle's position and travelable range, extracts nearby charging stations, and recommends nearby spots to visit while the vehicle is charging, transmitting this information to a navigation device for display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If a battery is charged at a charging station, then the vehicle can be recharged, but the driver experiences boredom due to the long waiting time

Engineering Contradiction:
Improvecharging timeVSAvoiddriver convenience
Core Design Contradiction:
Duration of action of moving objectVSEase of operation

Solution Approach 1:

The patent introduces an information processing device as an intermediary that provides spot information to the driver during charging. This mediator fills the idle time by offering useful content (spot recommendations with images and descriptions) that the driver can view through the navigation device, thereby improving driver convenience without affecting the charging process itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system allows the driver to independently browse and select spots of interest during the charging wait time. The information processing device automatically provides relevant spot information based on the charging station location, enabling the driver to self-entertain or plan activities without requiring additional service from charging station staff or other external assistance.

Inventive Principle:
Principle #25Self-service

2Duration of action of moving object

If the driver waits at the charging station, then the battery can be charged, but the waiting time is wasted without productive use

Engineering Contradiction:
Improvecharging durationVSAvoidwaiting time
Core Design Contradiction:
Duration of action of moving objectVSLoss of time

Solution Approach 1:

The patent converts the harmful aspect of long charging time (driver boredom and wasted time) into a beneficial experience by providing spot information. The previously idle waiting time is transformed into a useful period where the driver can explore potential destinations, view spot images and descriptions, and plan future activities, thereby gaining value from what was previously a wasteful period.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The system performs preliminary action by providing spot information and images to the driver before the charging is complete. This allows the driver to plan and prepare for future activities in advance, rather than having to make decisions after charging ends. The driver can review spot details and mentally prepare for the next destination during the charging wait time.

Inventive Principle:
Principle #10Preliminary action

AI summary

An information processing device includes a control unit configured to acquire information of a position and information of a travelable range of a vehicle which travels using a battery as an energy source, to extract a charging station located within the travelable range from the position out of a plurality of charging stations, to extract a spot which is able to be visited in a state in which the vehicle stops in the extracted charging station out of a plurality of spots, and to transmit information of the extracted spot along with information of the extracted charging station.
