Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional audio data output systems are used in vehicles, then security and regulatory compliance are maintained, but the system becomes inflexible and requires costly, time-consuming updates

Engineering Contradiction:

Improveflexibility of audio data updatesVSAvoidtime required for system updates

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system is divided into three distinct components: an authorized control device for managing audio data, an intermediary device for secure transmission, and an onboard vehicle system for output. This segmentation allows each component to be updated independently and enables flexible audio data updates without requiring system-wide disassembly or specialized technical knowledge, directly resolving the contradiction between maintaining security and achieving update flexibility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

An intermediary device is introduced between the authorized control device and the onboard vehicle system to facilitate secure wireless transmission of audio data. This intermediary enables flexible and rapid audio data updates while maintaining security through authenticated connections, eliminating the need for direct physical access or disassembly of the vehicle system.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If traditional audio data output systems are used in vehicles, then security control is maintained, but the system requires disassembly and specialized knowledge for updates

Engineering Contradiction:

Improveease of audio data updatesVSAvoidcomplexity of update process

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical/disassembly-based update process with a wireless communication system. The authorized control device and intermediary device use wireless networks to transmit audio data to the onboard vehicle system, eliminating the need for physical disassembly and specialized technical knowledge while maintaining security through authenticated connections.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The onboard vehicle system automatically receives and processes audio data updates through the intermediary device without requiring manual intervention or specialized knowledge. The system self-updates by receiving authenticated audio data packets wirelessly, making the update process as easy as connecting to a wireless network.

Inventive Principle:

Principle #25Self-service

3Productivity

If wireless transfer and direct coupling are implemented, then updating efficiency is improved, but security control requirements must be maintained

Engineering Contradiction:

Improveefficiency of audio data updatesVSAvoidsecurity control of audio data

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system performs preliminary authentication and authorization actions before allowing any audio data transmission. The authorized control device verifies credentials and establishes secure connections with the intermediary device and onboard vehicle system in advance, ensuring that only authenticated administrators can update audio data while maintaining high update efficiency through automated wireless processes.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where the onboard vehicle system confirms receipt and processing of audio data updates, and the authorized control device monitors the status of transmission. This feedback loop ensures secure and reliable updates while maintaining efficiency, as the system can verify the integrity and authenticity of each update operation.

Inventive Principle:

Principle #23Feedback

AI summary

Embodiments of the present disclosure provide for improved secure audio outputting onboard a vehicle. Some embodiments utilize an authorized control device that facilitates authenticated control of creation or other altering of a set of playable audio data. The playable audio data, or updates thereto, are pushable via at least one wireless communications network to at least one intermediary device, and forwarded to an onboard vehicle system onboard a particular vehicle. The onboard vehicle system subsequently may be controlled, for example locally via wired communication system, to perform output of audio via one or more audio outputs onboard the vehicle, in some embodiments without adjustable control of the set of playable audio data.
