Solution Overview

Problem

Current mobile device designs limit high-speed access to memory mediums, restricting data transfer rates between external devices and internal memory, which hampers efficient data exchange and processor bandwidth utilization.

Innovation Solution

A system incorporating a USB hub within the mobile device to facilitate high-speed connections between external devices, memory mediums, and processors, utilizing USB interfaces like HSIC, ULPI, and UTMI for data transfer, allowing for direct data pathways that bypass the processor and enable super-speed USB connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If data transfer goes through the processor, then data exchange can occur, but processor bandwidth is consumed and transfer speed is limited

Engineering Contradiction:

Improvedata transfer rateVSAvoidprocessor bandwidth availability

Core Design Contradiction:

SpeedVSProductivity

Solution Approach 1:

The system segments the data transfer path by introducing a USB hub that creates separate communication channels: one path for data transfers between external devices and memory medium, and another path for processor communications. This segmentation allows data transfers to occur independently without consuming processor bandwidth, resolving the contradiction between transfer speed and processor productivity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The USB hub acts as an intermediary device between the external device and the memory medium, enabling direct data transfers that bypass the processor. The hub mediates the communication by providing its own data transfer interface, thus improving transfer speed while preserving processor bandwidth for other tasks.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Speed

If traditional USB interfaces are used, then compatibility is maintained, but data transfer speed is limited to USB 2.0 rates

Engineering Contradiction:

Improvedata transfer rateVSAvoidinterface compatibility

Core Design Contradiction:

SpeedVSAdaptability or versatility

Solution Approach 1:

The USB hub is designed with multi-functionality to support both traditional USB 2.0 interfaces for compatibility and high-speed USB 3.0 interfaces for enhanced transfer rates. This universal design allows the system to maintain compatibility with existing USB devices while simultaneously enabling faster data transfers when high-speed interfaces are available, thus resolving the contradiction between speed and adaptability.

AI summary

System and method for providing a high speed connection to a memory medium of a mobile device. The mobile device may be a mobile phone or other type of portable electronic device. The memory medium may be removable and/or may be flash memory, as desired. The mobile device may include a USB hub that provides a direct high speed connection between an external device and a memory medium of the mobile device. The USB hub may also provide a connection (possibly high speed) between the external device and the processor of the mobile device. The mobile device may also include a high speed connection between the processor of the mobile device and the memory medium.
