Solution Overview

Problem

Existing anti-theft management systems fail to provide notifications to theft notification destinations when communication with in-vehicle devices is disrupted, such as when a vehicle is stolen and cannot establish communication with a set notification destination.

Innovation Solution

An anti-theft management device and system that includes a notification information-transmitting unit to send alerts to nearby vehicles within a communicable range when it determines a vehicle is stolen and cannot communicate with the set notification destination, using broadcast waves and relay devices to ensure notification is made.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the anti-theft management device transmits notification information to the set theft notification destination, then the notification can be delivered to the intended recipient, but communication may fail when the device is located outside communicable range

Engineering Contradiction:

Improvenotification delivery reliabilityVSAvoidcommunication range adaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces intermediate vehicles as mediators to relay notification information from the anti-theft management device to the theft notification destination. When the device cannot communicate directly with the destination, it transmits notification information to nearby vehicles within communicable range, which then forward the information to the destination, ensuring reliable delivery across extended ranges.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transforms the communication architecture from a single-point direct connection to a multi-node networked system. By introducing multiple intermediate vehicles as transmission nodes, the system creates redundant communication paths and extends the effective notification range beyond the direct communicable range of the anti-theft management device.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Device complexity

If the system uses direct communication only with the set notification destination, then the communication path is simple, but notification cannot be delivered when direct communication is unavailable

Engineering Contradiction:

Improvecommunication path complexityVSAvoidnotification delivery guarantee

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent implements preliminary action by having the anti-theft management device transmit notification information to multiple intermediate vehicles in advance, before the theft notification destination is reached. This ensures that at least one intermediate vehicle will be within communicable range of the destination and can successfully deliver the notification, providing redundant preparation for potential communication failures.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent provides beforehand cushioning by creating redundant communication paths through multiple intermediate vehicles. This redundancy acts as a buffer against communication failures, ensuring that if the direct path to the theft notification destination is unavailable, the notification can still be delivered through alternative intermediate vehicles, thus cushioning against delivery failures.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

An anti-theft management device includes a notification information-transmitting unit that transmits notification information to vehicles located within a communicable range when the notification information is not able to be transfer to a set theft notification destination and when it is determined that identification information of a determination target vehicle coincides with identification information of a stolen vehicle on the basis of theft information including the identification information of the stolen vehicle.
