Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Bluetooth BR/EDR and BLE technologies face challenges with high power consumption, limited range, and susceptibility to interference, necessitating improvements for more efficient wireless communication.

Innovation Solution

Wireless devices are configured to activate low energy (LE) wireless protocol modules and basic rate enhanced data rate (BREDR) modules upon powering on, and disable BREDR modules when no BREDR devices are paired or connected, transitioning to a BLE-only mode to conserve power and resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If BREDR modules are activated upon powering on to ensure compatibility with legacy Bluetooth devices, then adaptability is improved, but power consumption increases

Engineering Contradiction:

Improvecompatibility with legacy Bluetooth devicesVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic module activation where BREDR modules are enabled only when legacy Bluetooth devices are detected or connected, rather than being permanently activated. The system transitions between BLE-only mode and BREDR-enabled mode based on real-time connection status, optimizing power consumption while maintaining compatibility when needed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent extracts the BREDR functionality from the always-on state and activates it only when specifically required. By separating the BLE and BREDR module activation conditions, the system takes out the unnecessary power consumption associated with continuously running BREDR modules while preserving the ability to support legacy devices when encountered.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If BREDR modules remain active to support legacy device connections, then reliability is improved, but processing resource consumption increases

Engineering Contradiction:

Improvelegacy device connection supportVSAvoidprocessing resource consumption

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system dynamically adjusts BREDR module activation based on connection requirements. BREDR modules are activated only when legacy Bluetooth devices are detected or attempt to connect, ensuring reliable support for legacy devices while minimizing processing resource consumption during BLE-only operations.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system automatically detects the presence of legacy devices and activates BREDR modules as needed without requiring manual intervention. The wireless device monitors connection attempts and self-manages the activation state of BREDR modules, ensuring reliability while optimizing resource usage.

Inventive Principle:

Principle #25Self-service
