Solution Overview

Problem

Existing ZigBee commissioning methods pose security risks and are user-unfriendly, as new devices can join the wrong network and require users to manually enter access codes or bring devices close together for secure connection.

Innovation Solution

A point-to-point connection using a combo network device with a bridge device allows for seamless integration into a multi-hop network, eliminating the need for manual code entry and reducing security risks through a single-hop technology like Bluetooth Low Energy (BLE) for enhanced user interface and secure setup.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If classical commissioning or touchlink commissioning is used in ZigBee networks, then devices can join the network, but security risks increase and user-friendliness decreases due to manual code entry requirements and automatic network searching

Engineering Contradiction:
ImprovesecurityVSAvoiduser-friendliness
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a mobile device as an intermediary between the user and the ZigBee network commissioning process. The mobile device displays the installation code and manages the commissioning workflow, eliminating the need for users to manually enter codes while maintaining security. This intermediary approach resolves the contradiction by handling security-sensitive operations through a trusted intermediate device rather than direct user-device interaction.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The commissioning process is designed to be self-service oriented, where the system automatically manages code display and network joining procedures. The mobile device automatically retrieves and displays installation codes, and the ZigBee device automatically joins the network based on pre-configured parameters, eliminating manual code entry requirements while maintaining security through controlled code distribution.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If devices automatically search for and join ZigBee networks, then commissioning is simplified, but security risks increase as devices may join wrong networks

Engineering Contradiction:
Improveautomatic commissioningVSAvoidnetwork joining accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements preliminary action by pre-configuring ZigBee devices with installation codes during manufacturing. These codes are stored in the device's memory and used to automatically identify and join the correct network. The mobile device displays these pre-configured codes to users, enabling automatic commissioning without security risks of joining wrong networks, as the device only joins networks with matching installation codes.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If users manually enter access codes for device commissioning, then security is maintained, but ease of operation decreases due to code visibility and entry requirements

Engineering Contradiction:
ImprovesecurityVSAvoidcode entry process
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical manual code entry process with an electronic display system on a mobile device. Instead of requiring users to physically read and type installation codes, the system electronically displays the code on the user's mobile device screen, which they simply need to confirm. This substitution maintains security through controlled code distribution while dramatically improving ease of operation by eliminating manual typing and code visibility issues.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The present invention relates to methods and apparatuses for controlling commissioning of a network device (22) in a multi-hop network, e.g., ZigBee network, (200) of a multi-hop technology, wherein the network device (22) is a combo network device with a single-hop communication unit of a single-hop technology, e.g., Bluetooth Low Energy (BLE), for establishing a point-to-point connection and a multi-hop communication unit of the multi-hop technology for communicating with other network devices (20) of the multi-hop network in the multi-hop network (200). The single-hop connection of the network device (22) for commissioning allows seamless transfer from controlling the network device (22) via the single-hop network to controlling the network device (22) via the multi-hop network via a bridge device (25), without running the risk of unnecessarily looking for open networks, having to look up and enter an access key or bringing the network device (22) close to the bridge device (25), and whilst maintaining a secure setup.
