Solution Overview

Problem

Existing vehicle management systems, such as Japanese Patent Laying-Open No. 2022-064527, do not adequately address the notification of vehicle accidents to the owner of a leased power storage, making it difficult for the power storage owner to be informed of such incidents.

Innovation Solution

A method is implemented to determine if the vehicle has been involved in an accident, identify if the power storage owner is different from the vehicle owner, and notify the power storage owner's terminal of the accident, with additional features for insurance companies and lease services to manage damage and replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the vehicle owner is notified of accidents through existing systems, then the vehicle owner can recognize occurrence of the accident, but the power storage owner cannot be notified when the power storage is leased to a different owner

Engineering Contradiction:
Improveaccident notification informationVSAvoidnotification system adaptability to leased power storage
Core Design Contradiction:
Loss of informationVSAdaptability or versatility

Solution Approach 1:

The notification system uses the vehicle body as an intermediary carrier that permanently stores owner information and accident notification logic. When an accident occurs, the body automatically notifies the registered owner through terminal devices, ensuring the power storage owner receives notifications even when leased to different users.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system pre-stores owner information and notification settings in the vehicle body before leasing occurs. This preliminary configuration ensures that when accidents happen during the leasing period, the original owner is automatically notified without requiring real-time updates of ownership status.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If a comprehensive accident notification system is implemented for leased power storage, then the power storage owner can be properly notified of accidents, but the system complexity increases

Engineering Contradiction:
Improveaccident notification reliabilityVSAvoidnotification system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The notification system merges the power storage owner information management with the existing vehicle body control systems. By integrating owner information storage and accident detection functionality into the body's existing infrastructure, the system achieves reliable notification without proportionally increasing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The vehicle body autonomously determines when accidents occur using its own sensors and automatically notifies the owner through connected terminal devices. This self-service approach eliminates the need for complex manual notification procedures or additional intermediary systems.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If owner information is stored in the vehicle body, then the body can determine whether the power storage owner is identical to the vehicle owner, but additional storage requirements are created

Engineering Contradiction:
Improveowner identity determinationVSAvoidstored information quantity
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The system extracts only the essential owner identification information (such as owner ID or registration data) from complete owner profiles and stores only these minimal necessary data elements in the vehicle body. This extraction approach enables owner identity determination while minimizing the quantity of stored information.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

There is a method of managing a power storage, and the method includes determining whether or not a vehicle, including a body and a power storage mounted on the body, has been involved in an accident. The method also includes determining whether or not an owner of the power storage is the same as an owner of the body when it is determined that the vehicle has been involved in the accident. The method also includes notifying a terminal of the owner of the power storage of occurrence of the accident of the vehicle including the power storage when the owner of the power storage is determined as not being identical to the owner of the body.
