Solution Overview

Problem

The increasing popularity of wireless networking for connecting devices in residential and commercial buildings leads to multiple vendor-specific ecosystems with interoperability issues, resulting in duplicate device identifiers when transitioning devices between different vendor networks.

Innovation Solution

A method for device deduplication in Matter networks involves generating a unique identifier upon factory reset, which is shared with both a cloud service and a hub device, ensuring that the cloud service can correctly correlate and manage devices across multiple network paths, thereby eliminating duplicate identifiers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a device transitions from one vendor ecosystem to another vendor's Matter network, then interoperability is improved, but duplicate device identifiers are created causing network management issues

Engineering Contradiction:
ImproveinteroperabilityVSAvoidduplicate identifiers
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The device performs a factory reset before transitioning to a new vendor's Matter network, which clears previous vendor-specific identifiers and prepares the device to generate a new unique identifier that will be recognized across different vendor ecosystems, preventing duplicate identifier issues

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

A hub device acts as an intermediary between the electronic device and the second cloud service, receiving the unique identifier from the electronic device and forwarding it to the second cloud service, ensuring proper registration and deduplication across multiple network paths

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple cloud services are used for device management, then service versatility is improved, but device identifier duplication increases

Engineering Contradiction:
Improveservice versatilityVSAvoididentifier management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device generates a single universal unique identifier that works across multiple cloud services and vendor ecosystems, eliminating the need for separate identifiers for each service and simplifying identifier management while maintaining service versatility

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system implements feedback mechanisms where the unique identifier is sent to multiple cloud services through different paths (directly to first cloud service and via hub device to second cloud service), allowing each service to recognize and deduplicate device identities based on the shared identifier

Inventive Principle:
Principle #23Feedback

AI summary

Techniques and devices for device deduplication between home networks are described for generating a unique identifier in which an electronic device detects a factory reset and in response to the detecting, generates the unique identifier. The electronic device sends the unique identifier to a first cloud service, the sending being effective to cause the first cloud service to forward the unique identifier to a second cloud service, and the electronic device sends the unique identifier to a hub device in a Matter network, the sending being effective to cause the hub device to forward the unique identifier to the second cloud service.
