Solution Overview

Problem

Vehicles without communication functions or with disabled communication capabilities due to standard changes cannot receive services, and existing systems fail to ensure robust authentication over non-cellular networks.

Innovation Solution

An information processing apparatus equipped with a UICC for authentication, wireless and wired connection units, and a processor to transmit authentication data via non-cellular networks, enabling robust authentication and data transmission using a non-cellular network infrastructure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a vehicle uses a non-cellular network for communication, then it can maintain connectivity without cellular functionality, but robust authentication becomes difficult to ensure

Engineering Contradiction:
Improvenetwork connectivityVSAvoidauthentication
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a communication apparatus as an intermediary between the vehicle and the server. This intermediary performs authentication on behalf of the vehicle using a UICC (Universal Integrated Circuit Card) that stores authentication data, thereby enabling reliable authentication over non-cellular networks without requiring the vehicle itself to have authentication capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent uses a UICC that can store copies of authentication data (such as SIM card information) in the communication apparatus. This allows the vehicle to authenticate through the communication apparatus even though the vehicle lacks its own cellular communication functionality, effectively copying the authentication capability from a traditional cellular setup.

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If a vehicle lacks cellular network functionality, then it cannot perform traditional mobile communication, but it still needs to receive services as a connected car

Engineering Contradiction:
Improveservice reception capabilityVSAvoidcommunication system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The communication apparatus is designed to be universal, capable of performing multiple functions: it can establish connections via various networks (non-cellular networks like Wi-Fi, Bluetooth, or wired connections), perform authentication using a UICC, and communicate with both the vehicle and the server. This multi-functionality allows vehicles without cellular capabilities to still receive connected car services.

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

Solution Approach 2:

The communication apparatus serves as a mediator that bridges the gap between vehicles lacking cellular functionality and the service infrastructure. It handles all communication protocols, authentication, and data transmission, allowing the vehicle to receive services without needing its own complex communication system.

Inventive Principle:
Principle #24Intermediary (Mediator)
