Solution Overview

Problem

Existing lighting systems face challenges in establishing wireless connections between components without the use of Thread border routers and matter controllers, which are often unsuitable for professional applications like public parking garages or schools.

Innovation Solution

A method where networkable devices generate connection information using an algorithm based on a received network ID, eliminating the need for a controller and enabling devices to join the same network by generating the same connection information, with security enhanced by using hash algorithms or selecting predetermined parts of the network ID.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If Thread border router and matter controller are used for network installation, then connection information can be provided to devices, but the system complexity increases and it becomes unsuitable for professional applications

Engineering Contradiction:
Improvenetwork installationVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the connection information generation function from the border router and matter controller, enabling individual networkable devices to generate their own connection information using a shared algorithm. This eliminates the need for centralized controllers while maintaining ease of network installation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Networkable devices are enabled to self-generate connection information by executing the algorithm locally using the network ID. Each device independently performs the connection setup without requiring external controller intervention, achieving self-service capability.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If connection information is transmitted to devices to generate network, then devices can join the network, but security is compromised as connection information is exposed

Engineering Contradiction:
Improvenetwork connectivityVSAvoidsecurity
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts sensitive connection information (network key, network name) from the network ID through cryptographic algorithms. This allows devices to derive secure connection parameters without transmitting or storing actual connection information, enhancing security while maintaining network connectivity.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If different connection information is generated for different networks, then network segmentation is achieved, but the algorithm complexity increases

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

Solution Approach 1:

The patent uses parameter changes in the algorithm, such as incorporating a network identifier or salt value, to generate different connection information for different networks. This maintains algorithm simplicity while achieving proper network segmentation through parameter variation rather than structural complexity.

Inventive Principle:
Principle #35Parameter changes
