Solution Overview

Problem

Conventional out-of-band commissioning methods for small wireless node devices require bulky input devices, limiting their physical size and strategic placement, as they rely on displays, keyboards, or other cumbersome interfaces for network and security key management.

Innovation Solution

A method and system for out-of-band commissioning using a gesture-based approach, where a commissioning device generates a gesture code, and the node device receives and verifies this input, enabling secure pairing and commissioning without the need for bulky input devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional out-of-band commissioning methods are used, then network and security key management can be performed, but bulky input devices such as displays, keyboards, or keypads are required, which limits the physical size of wireless node devices and their strategic placement

Engineering Contradiction:

Improvecommissioning operationVSAvoiddevice size

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The patent replaces mechanical input devices (keyboards, keypads, displays) with an optical/gesture-based input system. The commissioning device captures gestures (e.g., hand movements) and converts them into commissioning commands, eliminating the need for physical buttons or displays on the wireless node device itself.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a commissioning device as an intermediary between the user and the wireless node device. This intermediary handles all the bulky input operations (displaying codes, receiving keyboard input, processing keypads) while the wireless node device only needs minimal gesture input capability, thus resolving the size constraint.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Volume of moving object

If gesture-based commissioning is implemented, then device size and placement flexibility are improved, but the complexity of gesture recognition and verification systems increases

Engineering Contradiction:

Improvedevice sizeVSAvoidcommissioning system complexity

Core Design Contradiction:

Volume of moving objectVSDevice complexity

Solution Approach 1:

The patent segments the commissioning system into distinct functional modules: gesture capture module, gesture recognition module, verification module, and commissioning module. This segmentation allows each module to be optimized independently and simplifies the overall system architecture by dividing the complex gesture-based commissioning process into manageable components.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements a feedback mechanism where the commissioning device displays gesture codes or verification information to the user, and the system adjusts based on user responses. This feedback loop simplifies the gesture recognition process by providing guidance and confirmation, reducing the complexity of ensuring accurate gesture input.

Inventive Principle:

Principle #23Feedback

AI summary

A method of performing out-of-band commissioning is provided. The method may include enabling a pairing mode on a commissioning device, generating a gesture code on the commissioning device, receiving a gesture input on a node device, verifying an agreement between the gesture code and the gesture input, and commissioning the node device based on the agreement.
