Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional multimedia content broadcasting systems require users to pay for service provider-managed radio frequency bands and public IPs, leading to inconvenience and potential loss of intellectual property ownership for individual users.

Innovation Solution

A private multimedia content broadcasting system using ISM or U-NII 5 GHz radio frequency bands, which allocates a private IP to receiving terminals through DHCP, allowing users to create, store, and broadcast content independently, with authentication and relay capabilities, and automatic playback tool installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a service provider's system is used for multimedia content broadcasting, then users can access broadcasting services, but users must pay service charges and lose control over their intellectual property

Engineering Contradiction:

Improveaccess to broadcasting serviceVSAvoidservice provider system dependency

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent segments the broadcasting system into independent user-owned components (broadcasting equipment, receiving terminals, DHCP server) rather than relying on a centralized service provider system. Each user can operate their own private network infrastructure, eliminating service charge dependencies while maintaining broadcasting functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent enables users to self-manage their broadcasting systems through automatic IP allocation via DHCP, autonomous content broadcasting, and independent network management. Users no longer need service provider authentication or intervention, achieving complete self-service operation while retaining intellectual property rights.

Inventive Principle:

Principle #25Self-service

2Ease of operation

If public IP is used for connection with service provider's system, then users can connect to broadcasting services, but users must pay additional service charges

Engineering Contradiction:

Improveconnection capabilityVSAvoidservice charge cost

Core Design Contradiction:

Ease of operationVSLoss of energy

Solution Approach 1:

The patent introduces a private IP addressing system with DHCP server as an intermediary between users and the broadcasting network. Instead of requiring public IPs and service provider gateways, users obtain private IPs automatically, enabling direct peer-to-peer connections that eliminate service charges while maintaining full connectivity.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If service provider's authentication system is used, then users can access protected content, but users must constantly request services and lose intellectual property ownership

Engineering Contradiction:

Improvecontent protectionVSAvoidservice access convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent inverts the traditional authentication model by making users the owners of their content and network resources rather than service consumers. Instead of service providers granting access rights, users inherently possess full control over their intellectual property and can selectively share it without external authentication constraints.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

An individual multimedia contents broadcasting equipment is disclosed, which includes an individual broadcast process unit which provides a private IP through a DHCP (Dynamic Host Configuration Protocol) to a receiving terminal, which requests a connection, and makes a connection of the receiving terminal through a radio network, and transmits a broadcast content to the connected receiving terminal; and a radio communication unit which forms a radio network and communicates data with the connected receiving terminal through the radio network.
