Solution Overview

Problem

Existing Bluetooth low energy (BLE) technologies face challenges in efficiently registering and managing electronic devices with varying mobility, communication capabilities, and user input convenience, leading to unintended registrations and increased power consumption.

Innovation Solution

An electronic device employs a two-step signal transmission process using a first advertising signal with a higher transmit power for initial discovery and a second signal with lower power for precise registration, combined with identity resolution and security verification, to enhance security and user experience while reducing power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a single high-power advertising signal is used for device discovery and registration, then the communication range and discovery capability are improved, but unintended registrations and security risks increase

Engineering Contradiction:

Improvecommunication rangeVSAvoidregistration accuracy

Core Design Contradiction:

Area of stationary objectVSReliability

Solution Approach 1:

The patent segments the advertising signal transmission into two distinct phases: a first advertising signal with higher transmit power for initial device discovery, and a second advertising signal with lower transmit power for precise registration verification. This segmentation allows the system to achieve both wide coverage for discovery and high accuracy for registration, resolving the contradiction between communication range and registration accuracy.

Inventive Principle:

Principle #1Segmentation

2Productivity

If continuous high-power advertising signals are transmitted to ensure device discovery, then the discovery capability is improved, but power consumption increases

Engineering Contradiction:

Improvedevice discovery efficiencyVSAvoidpower consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic action by transmitting advertising signals in distinct phases rather than continuously at high power. The first advertising signal is transmitted periodically for discovery, and upon successful connection, the second advertising signal is transmitted for verification. This periodic, phased approach maintains device discovery efficiency while significantly reducing overall power consumption compared to continuous high-power transmission.

Inventive Principle:

Principle #19Periodic action

3Reliability

If manual user input is required for device registration, then registration security is improved, but user convenience and registration speed deteriorate

Engineering Contradiction:

Improveregistration securityVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent applies self-service by enabling automatic device registration through the exchange and verification of advertising signals containing device identifiers. The system automatically verifies device identity through the second advertising signal without requiring manual user input, thus maintaining security through automated verification while significantly improving user convenience and registration speed.

Inventive Principle:

Principle #25Self-service

4Device complexity

If a single advertising signal is used for both discovery and registration, then the device complexity is reduced, but the ability to distinguish between intended and unintended registrations deteriorates

Engineering Contradiction:

Improvesignal transmission processVSAvoiddevice identification accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent segments the advertising signal process into two distinct types: the first advertising signal for device discovery and the second advertising signal for registration verification. Each signal type serves a specific function, allowing the system to maintain relatively simple device complexity while achieving high device identification accuracy through the differentiated signal exchange process.

Inventive Principle:

Principle #1Segmentation
