Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional hardware devices are used for biometric authentication, then authentication security is improved, but device complexity and cost increase

Engineering Contradiction:

Improveauthentication securityVSAvoidhardware device complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses a server as an intermediary to manage authentication. The server stores biometric templates and authentication credentials, and coordinates the authentication process between the mobile device and vehicle electronic device. This eliminates the need for complex local biometric hardware in the vehicle while maintaining security through centralized verification.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a digital copy of biometric data in the form of authentication credentials stored on the server and mobile device. Instead of requiring physical biometric sensors in the vehicle, the system uses copied biometric information (authentication credentials) that can be verified electronically, reducing hardware complexity while maintaining authentication reliability.

Inventive Principle:

Principle #26Copying

2Reliability

If additional hardware devices are used for biometric authentication, then authentication security is improved, but manufacturing cost increases

Engineering Contradiction:

Improveauthentication securityVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

By introducing a server as an intermediary, the system eliminates the need for expensive biometric authentication hardware in each vehicle. The server handles all complex biometric verification operations, allowing vehicles to use simpler, cheaper electronic devices for authentication communication.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces expensive, durable biometric hardware with software-based authentication credentials that can be distributed digitally. These digital credentials are cheaper to produce and distribute, even though they may need to be updated or reissued periodically.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Adaptability or versatility

If biometric authentication hardware is used, then authentication capability is improved, but reliability decreases due to degradation from external factors

Engineering Contradiction:

Improveauthentication capabilityVSAvoidhardware degradation resistance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system creates digital copies of biometric authentication data that can be stored and transmitted without physical degradation. Instead of relying on physical biometric sensors that may deteriorate from environmental factors, the patent uses digital authentication credentials that remain stable and can be reliably verified.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent replaces mechanical/physical biometric authentication systems with electronic/digital authentication mechanisms. This substitution eliminates the problem of hardware degradation from external factors like temperature, humidity, and physical wear, while maintaining or improving authentication capability through software-based verification.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Productivity

If direct communication between vehicle electronic device and mobile device is used, then authentication speed is improved, but communication security requirements increase

Engineering Contradiction:

Improveauthentication speedVSAvoidcommunication security

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The server acts as a trusted intermediary that establishes secure communication channels between the vehicle electronic device and mobile device. It manages authentication credentials and verifies identities, enabling fast direct communication while maintaining security through centralized credential management and verification.

Inventive Principle:

Principle #24Intermediary (Mediator)
