Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current navigation systems lack a standardized method for securely organizing and sharing location information among caravan participants, which can lead to inefficiencies and safety concerns during group travel.

Innovation Solution

A system that verifies a pass code using a reference code shared between users, allowing location information to be securely transmitted between vehicles within a caravan, ensuring only authorized vehicles can join and share their locations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If location information is shared openly among all users, then coordination and communication among caravan participants is improved, but security and authorization control deteriorate

Engineering Contradiction:

ImprovecoordinationVSAvoidsecurity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent introduces a server as an intermediary that mediates between users and location information. The server verifies pass codes and controls the distribution of location data, allowing open coordination while maintaining security through centralized authorization management.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If pass code verification is implemented for caravan organization, then security and authorization control are improved, but system complexity and operational difficulty worsen

Engineering Contradiction:

ImprovesecurityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system allows users to self-register and obtain pass codes automatically through the server without manual intervention. This automation reduces operational complexity while maintaining security, as users independently complete verification processes.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The server performs multiple functions including pass code verification, location information management, and user authentication in a single centralized system. This multi-functionality consolidates complexity into one component rather than distributing it across multiple systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If centralized server verification is used, then authorization control and security are improved, but communication speed and response time worsen

Engineering Contradiction:

Improveauthorization controlVSAvoidcommunication speed

Core Design Contradiction:

ReliabilityVSSpeed

Solution Approach 1:

Pass code verification is performed in advance before location information sharing begins. This preliminary authorization ensures security requirements are met before actual caravan coordination starts, allowing faster communication during the actual travel coordination phase.

Inventive Principle:

Principle #10Preliminary action

AI summary

A reference pass code is received from a first user. Location information of a vehicle of the first user is received from a first computer. A pass code is received from a second user. Location information of a vehicle of the second user is received from a second computer. One or more computer processors verify that the pass code received from the second user matches the reference pass code. Based on verification of the pass code received from the second user, the location information of the vehicle of the first user is transmitted to the second computer and the location information of the vehicle of the second user is transmitted to the first computer.
