Solution Overview

Problem

Existing vehicle management systems lack the ability to rapidly convert normal services into emergency support services during emergencies, requiring dedicated emergency vehicles and delaying response times.

Innovation Solution

An autonomous vehicle system equipped with a control unit that can detect emergencies and switch from normal services to emergency support services, including provision of resources and temporary infrastructure, with or without communication with a central server, allowing vehicles to autonomously provide emergency assistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dedicated emergency vehicles are used, then emergency support capability is ensured, but vehicle availability and response flexibility deteriorate

Engineering Contradiction:
Improveemergency support capabilityVSAvoidvehicle availability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent makes normal vehicles multi-functional by enabling them to switch between normal services and emergency support services. The control unit receives emergency information and automatically switches the vehicle from its normal function (e.g., delivery, transportation) to emergency support function, allowing any available vehicle to serve as an emergency response vehicle without requiring dedicated emergency vehicles.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Loss of time

If vehicles are converted to emergency services during emergencies, then response time is improved, but service stability deteriorates

Engineering Contradiction:
Improveresponse timeVSAvoidservice stability
Core Design Contradiction:
Loss of timeVSStability of the object's composition

Solution Approach 1:

The patent implements dynamic service switching where the vehicle's function is not fixed but can change based on emergency conditions. The control unit dynamically adjusts the vehicle's service mode by receiving emergency information and automatically transitioning from normal service to emergency support service, enabling rapid response while maintaining operational stability through automated control.

Inventive Principle:
Principle #15Dynamics

3Productivity

If autonomous emergency response is implemented, then operational efficiency is improved, but control complexity increases

Engineering Contradiction:
Improveoperational efficiencyVSAvoidcontrol complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent enables vehicles to autonomously respond to emergencies through self-service automation. When the control unit receives emergency information, it automatically switches the vehicle to emergency support mode without requiring manual intervention. The system independently processes emergency information, determines the need for service switching, and executes the transition, thereby improving operational efficiency while managing control complexity through automated decision-making.

Inventive Principle:
Principle #25Self-service

AI summary

A vehicle that is able to travel autonomously includes a control unit configured to perform: stopping a first service and executing a second service of emergency support when the emergency has occurred during execution of the first service; and executing movement to a predetermined position associated with the second service. An information processing device includes a control unit configured to perform: detecting occurrence of an emergency; and instructing a vehicle, which is able to travel autonomously and which is located in a predetermined range including an area in which the emergency has occurred, to stop a first service which is being executed and to execute a second service of emergency support.
