Solution Overview

Problem

Conventional in-vehicle systems fail to manage user getting on and off effectively, particularly in shared transportation vehicles, lacking robust authentication and authorization mechanisms to ensure secure and efficient passenger management.

Innovation Solution

An in-vehicle system equipped with a reading unit for identifying individuals, a communication unit for transmitting and receiving authentication information, and a getting-on-and-off authorization processor that authenticates users based on identification data and reservation information, integrating with an external device to manage access and authorize vehicle entry and exit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional in-vehicle systems are used without dedicated authentication mechanisms, then the system complexity is reduced, but the ability to manage user getting on and off effectively deteriorates

Engineering Contradiction:
Improveuser management capabilityVSAvoidauthentication system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The authentication system is nested within the existing in-vehicle system architecture. The reading unit, communication unit, and authorization processor are integrated as components of the vehicle's control system, allowing the authentication functionality to be embedded without requiring a completely separate system infrastructure.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

An external device acts as an intermediary between the vehicle's reading unit and the authorization processor. This external device receives identification information from the vehicle, performs authentication processing, and returns authentication results, thereby managing the complexity of authentication operations outside the vehicle system while maintaining effective user management.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If robust authentication mechanisms are implemented, then security against unauthorized access is improved, but the processing time for user authentication increases

Engineering Contradiction:
Improveauthentication securityVSAvoidauthentication processing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Identification information is read and prepared in advance by the reading unit before authentication is actually required. The system proactively captures identification data (such as IC card information or biometric data) as users approach or enter the vehicle, so that when authentication needs to occur, the data is already ready for immediate processing by the external device.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The external device serves as a dedicated authentication intermediary that handles the computationally intensive authentication processing outside the vehicle system. This separates the time-critical identification reading function (performed quickly by the vehicle's reading unit) from the security-critical authentication verification (performed by the specialized external device), optimizing both speed and security.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If simple identification methods are used, then the ease of operation is improved, but the measurement precision of user identification deteriorates

Engineering Contradiction:
Improveidentification accuracyVSAvoididentification process simplicity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The reading unit is designed to handle multiple types of identification information through a unified interface. It can read various forms of identification data (IC card information, barcode data, biometric information) using the same hardware component and communication protocol, allowing the system to maintain high identification accuracy across different user types while presenting a simple, consistent user experience.

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

Solution Approach 2:

The system creates digital copies of identification information (such as storing IC card data or biometric templates) for verification purposes. These digital copies enable precise matching and authentication without requiring users to physically present or manually input their identification details each time, thereby maintaining high identification accuracy while simplifying the interaction process.

Inventive Principle:
Principle #26Copying

AI summary

An in-vehicle system (20) used in a getting-on-and-off authentication system (1) includes: a reading unit (22) provided in a vehicle (V) to read identification information capable of identifying a person; a communication unit (24) that transmits the identification information read by the reading unit (22) to an external device (30) outside the vehicle (V) and receives retrieval result information retrieved on the basis of the identification information by the external device (30); and a getting-on-and-off authorization processor (25d) capable of executing a process of authorizing a getting on and off of a person specified by the identification information on the vehicle (V) on the basis of the retrieval result information received by the communication unit (24).
