Solution Overview

Problem

The provisioning process in Bluetooth mesh networks is inefficient when adding multiple devices, as only one device can be added at a time, limiting large-scale deployment efficiency.

Innovation Solution

A provisioning device with multiple link modules simultaneously establishes connections and executes provisioning procedures for multiple Bluetooth devices using a parallel mesh network joining mechanism, including GATT link establishment, authentication, key distribution, and address assignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single link module is used to establish GATT connections and execute provisioning procedures, then device complexity is reduced, but provisioning productivity deteriorates due to sequential processing of multiple Bluetooth devices

Engineering Contradiction:

Improveprovisioning efficiencyVSAvoidlink module quantity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The provisioning device divides its communication capability into multiple independent link modules, where each link module can independently establish GATT connections and execute provisioning procedures with different Bluetooth devices. This segmentation enables parallel processing of multiple provisioning operations simultaneously, directly resolving the technical contradiction by improving productivity through parallelization while maintaining manageable complexity through modular design

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each link module is designed with universal functionality to independently perform complete provisioning operations including GATT connection establishment, authentication, key distribution, and address assignment. This multi-functionality allows any link module to handle any Bluetooth device provisioning task, enabling flexible parallel processing and significantly improving provisioning efficiency for large-scale device deployment

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If multiple link modules are deployed to enable parallel provisioning, then provisioning productivity improves, but device complexity increases due to additional hardware components

Engineering Contradiction:

Improveprovisioning throughputVSAvoidsystem architecture

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system segments provisioning operations into independent link module instances, where each module operates autonomously to handle specific Bluetooth devices. This segmentation transforms the provisioning system into a scalable parallel architecture, improving throughput while maintaining manageable complexity through standardized modular units that can be incrementally added based on deployment needs

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system allows dynamic configuration of the number of active link modules based on provisioning workload requirements. By enabling parameter changes in the operational state (number of concurrent connections, module activation status), the system optimizes the balance between productivity and complexity, deploying additional modules only when provisioning throughput demands increase

Inventive Principle:

Principle #35Parameter changes

3Loss of time

If sequential provisioning is used for multiple Bluetooth devices, then device complexity remains low with single link module, but loss of time increases due to sequential processing

Engineering Contradiction:

Improvetotal provisioning timeVSAvoidconnection management

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The provisioning process is segmented into parallel execution streams, with each link module handling a separate Bluetooth device independently. This segmentation eliminates the sequential waiting time between device provisionings, reducing total provisioning time proportionally to the number of parallel link modules deployed, while connection management complexity is handled through standardized protocols for each module

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple link modules enable continuous provisioning operations where authentication, key distribution, and address assignment processes occur simultaneously for multiple devices rather than sequentially. This continuity of useful action eliminates idle time between provisioning operations, significantly reducing total provisioning time while maintaining manageable connection management through independent module operation

Inventive Principle:

Principle #20Continuity of useful action
