Solution Overview

Problem

The existing technologies require separate connections for USB wireless modems and storage devices, leading to inefficient use of USB interface resources and inconvenience due to the need for multiple devices and potential use of a USB hub, especially when limited USB interfaces are available.

Innovation Solution

A modem with integrated modulation/demodulation, hub, and storage modules, where the storage and modulation/demodulation functions are connected to the hub module, allowing simultaneous connection and initialization via a single USB interface, enabling mass data storage and reducing the need for additional USB devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate USB wireless modem and USB storage device are used, then wireless network access and data storage functions are achieved, but USB interface resources are occupied and device complexity increases

Engineering Contradiction:
Improvefunction integrationVSAvoidnumber of devices
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines wireless modem functionality and USB storage device functionality into a single integrated device. The storage module is integrated within the USB wireless modem, allowing both wireless network access and data storage operations to be performed through one device connected via a single USB interface, thereby reducing the number of separate devices needed.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated USB wireless modem is designed to perform multiple functions: wireless network communication and data storage. The device can operate as both a wireless network interface card and a USB storage device, enabling a single device to serve multiple purposes that previously required separate devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple USB devices are connected, then required functions are achieved, but USB interface resource occupation increases

Engineering Contradiction:
Improvefunctional capabilityVSAvoidUSB interface resources
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

By merging the wireless modem and storage device into one integrated unit, the patent reduces the quantity of USB devices that need to be connected. A single USB interface connection provides both wireless network access and data storage capabilities, conserving USB interface resources on the host device.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The multi-functional design allows one USB device to fulfill multiple roles (wireless network adapter and storage device), thereby reducing the overall number of USB device connections required and freeing up USB interface resources for other uses.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If USB hub is used to connect multiple devices, then connection flexibility is improved, but device complexity and potential failure points increase

Engineering Contradiction:
Improveconnection flexibilityVSAvoidsystem configuration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the storage device functionality from the need for separate USB devices and USB hubs. By integrating storage directly into the wireless modem, the system eliminates the requirement for additional USB hubs or multiple device connections, simplifying the overall system configuration while maintaining connection flexibility.

Inventive Principle:
Principle #2Taking out (Extraction)
