Solution Overview

Problem

Existing trunk-sharing systems do not allow third parties to easily access and use permission information for vehicle cargo compartments, limiting the sharing of these compartments without compromising user convenience or privacy.

Innovation Solution

A trunk-sharing system that includes a server capable of acquiring and providing permission information for vehicle compartments, allowing users to request and obtain authentication for locking and unlocking these compartments, while ensuring that only authorized users can access and use them.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If use permission information for vehicle cargo compartments is kept private among owners and deliverers, then user privacy and security are protected, but third parties cannot easily access and use these compartments for sharing purposes

Engineering Contradiction:
Improvetrunk-sharing capabilityVSAvoidaccess to use permission information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent introduces a server as an intermediary between vehicle owners and third-party users. The server stores use permission information provided by owners and makes it accessible to third parties through authentication processes, enabling trunk-sharing while maintaining controlled access and privacy protection

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If use permission information is made accessible to third parties through a server, then trunk-sharing convenience is improved, but privacy and security control becomes more complex

Engineering Contradiction:
Improveaccess to use permission informationVSAvoidsystem structure for information management
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system enables vehicle owners to self-register their cargo compartments and usage conditions on the server, and third-party users to self-authenticate and access permitted compartments without manual intervention from owners, reducing operational complexity while maintaining security

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The server acts as a centralized information management platform that automatically handles authentication, authorization, and information distribution, simplifying the overall system architecture compared to peer-to-peer information sharing

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If authentication information is issued to third-party users for accessing cargo compartments, then sharing functionality is enabled, but risk of unauthorized access increases

Engineering Contradiction:
Improvetrunk-sharing functionalityVSAvoidsecurity control
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary authentication and authorization checks before issuing access permissions to third-party users. The server verifies user credentials and validates against stored use permission information before granting access, preventing unauthorized access before it can occur

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements authentication feedback mechanisms where the server continuously monitors and validates user identities and permissions, providing real-time verification to ensure only authorized users can access specific cargo compartments

Inventive Principle:
Principle #23Feedback

AI summary

A trunk-sharing system that controls an user's authority to use a predetermined area of a vehicle by issuing a predetermined authentication information to a user terminal, the trunk-sharing system including a server configured to: acquire a first information on a permission of using the predetermined area of the vehicle from a first user who owns the vehicle; provide the first information such that the first information acquired from the first user of each of a plurality of vehicles is able to be detected by a second user other than the first user; acquire a second information on a request for a use of the predetermined area which is an information from the second user who has accessed the provided first information; and issue an authentication information for locking and unlocking the predetermined area to a terminal of the second user based on the first information and the second information.
