Solution Overview

Problem

Current wireless USB communication methods require separate wire adapters for association between USB hosts and devices, which is inefficient, especially for devices lacking number pads like printers and digital cameras.

Innovation Solution

A USB device with an internal circuit and interface circuit that enables wireless USB (WUSB) communication and USB communication without separate wire adapters, using a WUSB module, OTG module, and interface module to control communication between USB hosts and devices, allowing direct association and data transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate wire adapters are used for WUSB association, then compatibility with conventional USB hosts and devices is achieved, but device complexity and operational convenience deteriorate

Engineering Contradiction:

ImprovecompatibilityVSAvoidcomplexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the WUSB module and OTG module into a single USB device, merging wireless USB functionality and USB communication capabilities into one integrated unit. This eliminates the need for separate wire adapters while maintaining compatibility with both wireless and wired USB connections.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The USB device is designed with multi-functionality, capable of operating in both WUSB mode and USB mode. The interface module selectively controls which module operates based on connection type, making the device universally compatible with different USB hosts and communication protocols without requiring separate adapters.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If separate wire adapters are used for WUSB association, then conventional USB software sources are adapted, but ease of operation deteriorates due to number pad requirements

Engineering Contradiction:

Improvesoftware compatibilityVSAvoidoperational convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The USB device performs association automatically through the interface module, which selectively controls the WUSB or OTG module based on connection type. This self-service capability eliminates the need for manual number pad input during association, making the device easy to operate while maintaining software compatibility.

Inventive Principle:

Principle #25Self-service

3Productivity

If WUSB module and OTG module are integrated in one device, then productivity improves by eliminating separate adapters, but device complexity increases

Engineering Contradiction:

Improvecommunication efficiencyVSAvoidinternal structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent merges the WUSB module and OTG module into a single integrated USB device with a unified structure. The interface module coordinates between the two functional modules, enabling direct wireless USB communication without external adapters while maintaining organized internal architecture.

Inventive Principle:

Principle #5Merging (Combining)
