Solution Overview

Problem

Bluetooth Low Energy (BLE) compliant beacon sensor devices are limited in their ability to advertise multiple service sets and communicate with network devices using different advertisement data frame formats, restricting their role and functionality.

Innovation Solution

A beacon sensor device capable of behaving as multiple devices, cycling through different advertisement data frame formats to allow network devices to connect and communicate effectively, enabling it to operate in peripheral mode and transmit various types of advertisement frames.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a beacon sensor device uses a single advertisement data frame format, then the device complexity is reduced and ease of operation is improved, but the adaptability and versatility are limited

Engineering Contradiction:

Improveability to communicate with network devices using different formatsVSAvoidcomplexity of cycling through multiple advertisement formats

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The beacon sensor device dynamically switches between different advertisement data frame formats by cycling through them at defined intervals. This dynamic behavior allows the device to adapt to different network device requirements without requiring multiple static configurations, resolving the contradiction between versatility and complexity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The device implements periodic transmission of advertisement frames in different formats, where each format is transmitted for a defined time interval before switching to the next format. This periodic action enables multiple formats to be supported while maintaining a simple, rhythmic transmission pattern that doesn't significantly increase operational complexity.

Inventive Principle:

Principle #19Periodic action

2Adaptability or versatility

If a beacon sensor device cycles through multiple advertisement data frame formats, then the adaptability and versatility are improved, but the loss of time and productivity are worsened

Engineering Contradiction:

Improveability to advertise multiple service setsVSAvoidtime required to cycle through different formats

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The device transmits each advertisement format for a defined time interval that is sufficient to allow network devices to detect and process the advertisement, but not necessarily long enough to exhaustively demonstrate all formats. This partial action approach reduces the total time spent cycling through formats while still achieving the goal of enabling connections with various network devices.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A beacon sensor device may include a communication resource to transmit a plurality of advertisement types. Each of the plurality of advertisement types may include a plurality of advertisement frames. The communication resource may further receive a connection request from a network device. The beacon sensor device may further include a processing resource and a memory resource storing machine-readable instructions. The machine-readable instructions may cause the processing resource to determine that the connection request is made in response to the transmission of a particular advertisement type of the plurality of advertisement type. The instructions may further cause the processing resource to determine the active services associated with the particular advertisement type and enable the services associated with the particular advertisement type.
