Solution Overview

Problem

Existing peer-to-peer network systems face limitations in scaling to a large number of terminals due to physical factors, such as terminal and network circuit performance, particularly when handling large data transfers like audio communications, where the number of connectable terminals is typically limited to around 80.

Innovation Solution

A network system is designed with a hierarchical structure of master and slave terminals, where master terminals communicate with each other and relay synthesized audio data across groups, reducing direct connections between all terminals and allowing for flexible network reconfiguration, enabling communication among a large number of terminals without physical limitations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If peer-to-peer communication is used to connect a large number of terminals, then direct communication between terminals is enabled, but the number of connectable terminals is limited to about 80 due to terminal and network circuit performance

Engineering Contradiction:
Improvenumber of connectable terminalsVSAvoidnetwork structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The network system divides terminals into multiple groups, with each group managed by a master terminal. This segmentation allows the network to scale beyond the 80-terminal limit by distributing communication management across multiple master terminals, where each master handles a subset of slave terminals independently

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Master terminals act as intermediaries between slave terminals and the rest of the network. Instead of direct peer-to-peer connections between all terminals, communication is routed through master terminals, reducing the connection burden on individual terminals while enabling larger network scale

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If all terminals are directly connected in a peer-to-peer network, then any terminal can communicate with any other terminal, but the load on each terminal and network circuit increases significantly

Engineering Contradiction:
Improvecommunication flexibilityVSAvoidterminal load
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The network divides communication load by segmenting terminals into groups under different masters. Each terminal only needs to maintain connections with its master terminal rather than all other terminals, significantly reducing the number of active connections and processing load per terminal

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple slave terminals are merged under a single master terminal's management. The master terminal consolidates communication tasks, synthesizing audio data from multiple slaves and managing external communications, thereby distributing and reducing individual terminal loads

Inventive Principle:
Principle #5Merging (Combining)

3Quantity of substance

If the number of terminals in a peer-to-peer network is increased beyond 80, then more users can communicate, but physical limitations of terminals and network circuits prevent further expansion

Engineering Contradiction:
Improvenumber of terminalsVSAvoidnetwork stability
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The network transitions from a flat peer-to-peer structure to a hierarchical structure with multiple levels (slaves to masters, and masters interconnecting). This dimensional change allows the network to scale to thousands of terminals by adding hierarchical layers rather than increasing connections at the same level

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

AI summary

A network system is constructed by connecting a plurality of terminals to each other so that information such as audio data can be sent and/or received through peer-to-peer communication. The network system includes a plurality of groups each constituted from a plurality of terminals that execute the peer-to-peer communication with each other. Each group includes a master terminal connected to other terminals in the group and a plurality of slave terminals each connected to the master terminal. Each of the slave terminals communicates with the master terminal and the other slave terminals in the group. The master terminal communicates with master terminals in other groups in addition to the slave terminals in the group. In the case where a slave terminal communicates with a terminal in any other group, the slave terminal communicates with the terminal via the master terminal in the group to which the slave terminal belongs.
