Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing telemedicine solutions are costly, difficult to set up, and not adaptable for small practices, leading to high traffic load at central hubs and incompatibility with existing hospital equipment, while existing NAT traversal techniques are not optimized for high-bandwidth multimedia communication.

Innovation Solution

A scalable, peer-to-peer network system with a constellation topology allows connectivity optimization by initiating sessions from spoke sites with private addressing to hubs with public addressing, using a store-and-forward infrastructure for consultation requests and integrating video conferencing equipment with adaptable and secure communication channels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing network telemedicine solutions use sophisticated video conference equipment with central hubs, then communication quality is improved, but device complexity and cost increase

Engineering Contradiction:

Improvecommunication qualityVSAvoidequipment complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the centralized hub-and-spoke architecture into a distributed peer-to-peer network where each participant has equal status. This eliminates the need for sophisticated central hub equipment while maintaining communication quality through direct peer connections, reducing overall device complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent inverts the traditional hub-and-spoke model by making each participant a peer capable of initiating connections. Instead of clients connecting to a central hub, the architecture allows bidirectional peer-to-peer communication, simplifying equipment requirements while maintaining reliability.

Inventive Principle:

Principle #13The other way round (Inversion)

2Productivity

If existing solutions use central web portals for high-speed multi-media traffic, then communication capability is improved, but loss of time and cost increase

Engineering Contradiction:

Improvecommunication capabilityVSAvoidsetup and maintenance time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent extracts the communication functionality from centralized web portals and distributes it to individual peers. Each peer can directly establish connections without requiring complex portal infrastructure, reducing setup and maintenance time while maintaining high-speed communication capability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system enables self-service operation where peers automatically discover and connect to each other without requiring centralized portal management. This eliminates the need for knowledgeable personnel to manage complex web portal infrastructure, reducing time loss while preserving communication productivity.

Inventive Principle:

Principle #25Self-service

3Quantity of substance

If satellite spoke sites capture and submit unfiltered data to central hub database, then data collection is improved, but loss of substance increases

Engineering Contradiction:

Improvedata collectionVSAvoidunnecessary data transmission

Core Design Contradiction:

Quantity of substanceVSLoss of substance

Solution Approach 1:

The patent implements local data processing at each peer, where data is filtered and processed locally before transmission. This ensures that only necessary data is transmitted across the network, reducing unnecessary data transfer while maintaining comprehensive data collection capabilities through local quality control.

Inventive Principle:

Principle #3Local quality

4Ease of manufacture

If existing telemedicine devices are prepackaged for specialty categories, then ease of manufacture is improved, but adaptability decreases

Engineering Contradiction:

Improveprepackaged designVSAvoidadaptability for additional categories

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal communication platform where peers can be dynamically configured for different specialty categories through software rather than hardware. This maintains ease of manufacture through standardized peer units while achieving high adaptability by allowing peers to serve multiple functions through configurable protocols and data formats.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A multi-party conference system for multi-media multi-party conference communication, includes one or more multi-media encoding/decoding modules to support processing/transcoding multi-media text/file/audio/video for conferencing communication; code for retrieving a plurality of communication attributes for a peer client used by a user to log in and stay present, wherein said client program is an end-user program or a user's proxy program, and wherein said program is configured with privilege access to a list of public known routers; code for processing the communication attributes profile for said clients coupled with validation through executing dynamic IP address learning techniques to determine an addressing mode for each said client, wherein said addressing mode is a private addressing mode (associated with NATed type), or a “privilege” addressing mode (associated with Privileged NATed type); and code for cross-domain communication to other systems in other social network addressing domains coupled with other social network processing systems.
