Solution Overview

Problem

Existing multimedia servers and USB hubs are limited in the number of accessible USB media data storage devices and consume excessive energy due to their design, restricting the ability to manage a large number of electronic devices and USB storage devices efficiently.

Innovation Solution

A multimedia server with multiple USB connections and a processing unit that establishes exclusive one-by-one data connections between electronic devices and USB storage devices, allowing up to 64 USB connections, and implementing a cascading architecture with switchboards to manage a large number of devices while optimizing power supply to conserve energy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a USB hub is used to connect multiple USB storage devices, then the number of accessible devices is increased, but the system complexity and power consumption increase significantly

Engineering Contradiction:
Improvenumber of accessible USB storage devicesVSAvoidsystem complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The system segments the connection architecture by introducing a server as an intermediary between USB storage devices and electronic devices. Instead of directly connecting multiple devices to a hub, the server manages individual connections, dividing the system into storage management (server) and data consumption (electronic device) functions. This reduces overall system complexity while maintaining scalability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The server acts as an intermediary component that mediates between USB storage devices and electronic devices. It establishes one-by-one data connections, managing the interaction between storage and consumption sides. This intermediary approach simplifies the connection model compared to direct hub connections while enabling efficient resource management.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If a USB hub provides power to all connected devices, then all devices remain accessible, but energy consumption increases unnecessarily

Engineering Contradiction:
Improvenumber of accessible USB storage devicesVSAvoidpower consumption
Core Design Contradiction:
Quantity of substanceVSUse of energy by moving object

Solution Approach 1:

The server implements periodic or on-demand power supply to USB storage devices based on actual data access requirements. Instead of continuous power supply like traditional hubs, the server activates power only when data connections are established, creating a periodic action pattern that matches actual usage and significantly reduces energy consumption.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system applies local quality by providing power selectively to specific USB storage devices that are currently being accessed, rather than uniformly powering all connected devices. This localized power supply approach ensures energy is consumed only where and when needed, optimizing the energy efficiency of the storage system.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If NAS servers are used to manage multiple media files, then data sharing capability is improved, but the cost and complexity of the system increase

Engineering Contradiction:
Improvedata sharing capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The server is designed with multi-functionality, serving both as a storage management system and a data sharing platform. It can handle multiple types of USB storage devices and support various electronic devices simultaneously, providing universal data access without requiring specialized NAS hardware. This universal approach maintains versatility while reducing system complexity and cost.

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

4Ease of operation

If conventional USB hubs are used, then device connectivity is simplified, but the number of manageable devices is limited

Engineering Contradiction:
Improvedevice connectivityVSAvoidnumber of manageable devices
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The system transitions from a flat, direct connection model (hub to devices) to a hierarchical model with the server as an intermediate layer. This dimensional change in the connection architecture enables the system to manage a much larger number of devices by introducing abstraction and management layers, effectively expanding the scalable capacity beyond physical hub limitations.

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