Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional head units are inadequate in supporting multiple smartphones for simultaneous streaming services, primarily designed to handle only one smartphone at a time, limiting their ability to provide seamless service conversion between different mobile terminals.

Innovation Solution

A head unit with a resource controller that allows multiple mobile terminals to access and exclusively reproduce resources such as audio, video, and microphone, ensuring only one content is occupied per resource type, and includes a short-range communication module for seamless connectivity and content management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the head unit is designed to handle only one smartphone at a time, then the device complexity is reduced and ease of operation is improved, but the adaptability to support multiple streaming services simultaneously deteriorates

Engineering Contradiction:

Improvesupport for multiple streaming servicesVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The head unit divides resources into separate categories (audio resources, video resources, microphone resources) and manages each category independently. This segmentation allows multiple streaming services to be supported simultaneously by allocating different resource types to different services, resolving the contradiction between supporting multiple services and maintaining device complexity at manageable levels.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the head unit exclusively reproduces each resource for one content, then the reliability of resource allocation is improved, but the adaptability to allow service conversion between different mobile terminals deteriorates

Engineering Contradiction:

Improveservice conversion capabilityVSAvoidresource allocation reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The head unit implements dynamic resource allocation where the exclusive reproduction assignment can be changed based on service conversion requests. When a service conversion is requested, the system dynamically reassigns resources from the current service to the new service, maintaining reliability through controlled transitions while enabling adaptability for service conversion between different mobile terminals.

AI summary

A head unit for a vehicle, for providing a multi-streaming service between different devices is disclosed. The head unit includes a resource controller for permitting access of a plurality of mobile terminals and exclusively reproducing each resource so as to occupy only one content in each resource within a control range for each respective content of at least one content provided from a plurality of accessed mobile terminals. Thus, various mobile terminals (e.g. smartphones) are simultaneously connected and resources are exclusively used so as to enable a seamless multi-streaming service, thereby enhancing user convenience.
