Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional Bluetooth Low Energy (BLE) beacon devices are limited in their applicability due to one-way message transmission and the need to repeatedly stop and restart advertising packet broadcasts to change content, which is inconvenient for users and inefficient.

Innovation Solution

A BLE beacon device and method that enables the simultaneous broadcast of multiple different advertising packets, including connectable and unconnectable types, with customizable advertising time intervals and address codes, allowing for sequential execution without repeated parameter changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the BLE beacon device sends only one type of advertising packet continuously, then the broadcasting is simple and stable, but the device cannot perform multiple types of advertising broadcasts simultaneously and cannot achieve multicast functionality

Engineering Contradiction:

Improveadvertising packet type diversityVSAvoidcontroller parameter settings

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The advertising packets are segmented into different types (connectable and unconnectable) with distinct identifiers. The controller divides the broadcasting task by assigning different advertising packet types to different time slots or identification fields, allowing simultaneous support for multiple packet types without requiring complex parameter reconfiguration.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The advertising packet structure is designed with a universal format that includes a packet type identifier field. This allows the same hardware controller to handle multiple advertising packet types (connectable, unconnectable, multicast) through a unified broadcasting mechanism, eliminating the need for separate configuration modes for each packet type.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the BLE beacon device needs to change advertising content, then the information update capability is improved, but the device must stop and restart the broadcast action which reduces efficiency

Engineering Contradiction:

Improveadvertising content update capabilityVSAvoidbroadcasting efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

Multiple advertising packet types and their corresponding content are prepared and configured in advance within the controller. The system pre-loads different advertising data sets and assigns them to different packet types or time slots, so that content changes can occur seamlessly during broadcasting without requiring the device to stop and restart the broadcast action.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The advertising packet structure includes dynamic fields that can be updated without stopping the broadcast. The controller dynamically switches between different advertising packet types and content based on time slots or identification fields, allowing continuous broadcasting while updating information content.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the BLE beacon device uses one-way message transmission only, then the device structure is simple, but the applicability is limited and cannot support two-way communication

Engineering Contradiction:

Improvecommunication mode flexibilityVSAvoidconnection establishment

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system implements partial two-way communication capability by including both connectable and unconnectable advertising packet types. Connectable packets enable devices that require interaction to establish connections, while unconnectable packets maintain simple one-way broadcasting for devices that don't need connection. This partial implementation of two-way communication adds versatility without requiring full connection establishment for all advertising scenarios.

Inventive Principle:

Principle #16Partial or excessive action
