Problem

Traditional IoT networks suffer from a single-point-of-failure due to a single master node, which can disrupt network monitoring and control, necessitating a decentralized solution to ensure reliability and scalability.

Innovation Solution

A layered network architecture utilizing blockchain transactions, where multiple master IoT nodes control subsets of intermediate nodes and end devices, enabling decentralized communication and control, with backup nodes taking over in case of failures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single master node is used to control IoT networks, then the control structure is simple and easy to manage, but the system reliability deteriorates due to single-point-of-failure

Engineering Contradiction:
Improvecontrol structure complexityVSAvoidnetwork reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent divides the single master node into multiple master nodes (first master node, second master node, etc.), each controlling different subsets of intermediate nodes and end devices. This segmentation eliminates the single-point-of-failure while distributing control responsibilities across multiple nodes, thereby improving reliability without significantly increasing overall system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each master node is assigned specific control responsibilities for particular subsets of intermediate nodes and end devices, creating localized control zones. This allows each master node to operate independently within its designated scope, improving overall network reliability while maintaining manageable control structures through specialized local control.

Inventive Principle:
Principle #3Local quality

2Reliability

If multiple master nodes are deployed to eliminate single-point-of-failure, then network reliability improves, but the device complexity increases

Engineering Contradiction:
Improvenetwork reliabilityVSAvoidcontrol structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the network into distinct control zones with dedicated master nodes, where each master node manages specific intermediate nodes and end devices. This segmentation allows parallel operation of multiple master nodes with well-defined boundaries, improving reliability while preventing complexity from becoming unmanageable through clear division of responsibilities.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a hierarchical dimension to the network architecture, organizing master nodes, intermediate nodes, and end devices into distinct layers. This dimensional organization allows multiple master nodes to operate at the same hierarchical level while maintaining clear control relationships, thereby scaling reliability without proportionally increasing control complexity.

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

3Adaptability or versatility

If a decentralized layered network architecture is implemented, then reliability and scalability improve, but the system complexity increases

Engineering Contradiction:
Improvenetwork scalabilityVSAvoidarchitecture complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the IoT network into distinct layers (master node layer, intermediate node layer, end device layer) with clear functional boundaries. Each layer operates semi-independently, allowing the system to scale by adding nodes at any layer without fundamentally changing the overall architecture, thus improving scalability while managing complexity through layered organization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements a three-dimensional hierarchical architecture spanning master nodes, intermediate nodes, and end devices. This dimensional structure allows the system to scale vertically (adding layers) and horizontally (adding nodes within layers) while maintaining consistent control patterns, thereby enhancing adaptability and scalability without linearly increasing architectural complexity.

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