Solution Overview

Problem

Existing vehicle head units struggle to maintain up-to-date functionality and comply with local driving restrictions, limiting their ability to display a wide range of content types and requiring frequent updates, which complicates the integration of the latest IT and CE technologies.

Innovation Solution

An automotive electronic device and method that involves receiving content from a service provision server, acquiring meta information, and determining displayable portions based on content restriction information and vehicle travel information, allowing for dynamic content rendering on a web browser while adhering to driving restrictions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a head unit uses an application of a smart phone, then the head unit can display mobile application data, but the head unit requires a module to receive, process and display data from added applications, increasing device complexity

Engineering Contradiction:
Improvecapability to display mobile application dataVSAvoidmodule complexity for receiving and processing application data
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a server as an intermediary between the smartphone application and the head unit. The server receives data from the smartphone, processes it, and transmits only relevant information to the head unit. This eliminates the need for the head unit to have complex modules for receiving and processing all application data, while still enabling display capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If a head unit directly downloads an application from an application store, then the head unit can update applications independently, but the user has to additionally perform the process of downloading and updating the application

Engineering Contradiction:
Improveindependent application update capabilityVSAvoidtime required for downloading and updating applications
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The server performs preliminary actions by pre-processing application data and preparing it for transmission to the head unit. This allows the head unit to receive ready-to-use information without requiring users to manually download or update applications, saving time and effort.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If a head unit receives a cloud service via a web browser, then the head unit can access cloud services directly, but contents that violate driving restrictions cannot be verified

Engineering Contradiction:
Improvedirect cloud service access capabilityVSAvoidverification of driving restriction compliance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The server acts as an intermediary that verifies driving restriction compliance before transmitting content to the head unit. It receives content from cloud services, checks it against driving restrictions, and only transmits compliant content to the head unit, ensuring reliability while maintaining direct cloud service access capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Stability of the object's composition

If a head unit uses a fixed hardware and software configuration, then the head unit is stable, but the latest IT and CE technologies cannot be continuously used in the vehicle

Engineering Contradiction:
Improvehardware and software stabilityVSAvoidability to use latest technologies
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent moves the update capability to a different dimension - instead of updating hardware and software in the head unit, the system updates data and content on the server side. The head unit maintains stable hardware and software while receiving updated information through the server, enabling continuous access to latest technologies without compromising stability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
