Solution Overview

Problem

Conventional centralized wireless network deployment methods are inflexible, difficult to extend communication distances, and lack effective communication relay, making them unsuitable for distributed configurations and adaptive network topologies, especially in environments with obstacles and mobile devices.

Innovation Solution

A self-organized network is established using decentralized, unstructured nodes with middleware that dynamically determines nodal topology and switches between source, relay, and target nodes based on current message exchange status, enabling peer-to-peer communication links to adaptively expand network coverage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If a centralized wireless network deployment method with AP as center point is used, then the total communication distance from AP to all networked devices is minimized, but the network deployment locations are greatly limited and difficult to avoid obstacles for communication

Engineering Contradiction:

Improvetotal communication distanceVSAvoidnetwork deployment flexibility

Core Design Contradiction:

Length of moving objectVSAdaptability or versatility

Solution Approach 1:

The network is segmented into multiple peer-to-peer connected nodes rather than a single centralized AP. Each node can independently establish connections with neighboring nodes, creating a distributed network structure that avoids obstacles and adapts to environmental constraints while maintaining communication efficiency.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The network topology dynamically adapts based on environmental conditions, node positions, and communication requirements. Nodes can switch between different roles (source, relay, target) and the network automatically reconfigures to avoid obstacles and optimize communication paths, providing versatile deployment flexibility.

Inventive Principle:

Principle #15Dynamics

2Device complexity

If a centralized wireless network deployment method is used, then the network structure is simple and easy to manage, but it is disadvantageous for distributed configuration of the networked devices and difficult to extend the communication distances

Engineering Contradiction:

Improvenetwork structure complexityVSAvoiddistributed configuration capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

Each network node autonomously performs discovery, connection establishment, and role assignment without requiring centralized coordination. The nodes self-organize into a functional network structure, enabling distributed configuration while maintaining manageable complexity through standardized peer-to-peer interaction protocols.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Each node in the network is multi-functional, capable of acting as source, relay, or target node depending on communication requirements. This universal capability allows any node to participate in various network roles, enabling flexible distributed configuration and extended communication distances through multi-hop relay paths.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of manufacture

If a centralized wireless network deployment method is used, then the network configuration is easy to establish, but it lacks application of communication relay and has inflexible network topology routing

Engineering Contradiction:

Improvenetwork configuration easeVSAvoidcommunication relay capability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

Intermediate relay nodes are introduced to forward communications between source and target nodes. These relay nodes extend communication distances and improve reliability by providing alternative paths when direct connections are blocked, while the overall network configuration remains simple through automated peer-to-peer establishment protocols.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Ease of operation

If conventional structured and centralized wireless network deployment method is used, then the deployment process is straightforward, but the network topology is inflexible and cannot adaptively change in response to environmental status

Engineering Contradiction:

Improvedeployment process simplicityVSAvoidtopology adaptability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The network continuously monitors environmental status, node positions, and communication quality, using this feedback to dynamically adjust topology and routing decisions. This feedback mechanism enables adaptive topology changes while maintaining straightforward deployment through automated self-configuration protocols that require minimal manual intervention.

Inventive Principle:

Principle #23Feedback
