Solution Overview

Problem

Conventional Bluetooth technologies face challenges in maintaining optimal audio streaming quality due to continuous transmission failures caused by environmental factors like increased connection distance and RF interference, leading to packet loss and sound discontinuation, while continuous retransmission of audio packets negatively affects the RF environment of other devices.

Innovation Solution

An electronic device with a communication interface and controller dynamically determines or changes packet data configurations based on detected communication states, allowing for optimal audio streaming by adjusting packet transmission rates, frame sizes, and retransmission rates to adapt to varying wireless and device environments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If continuous retransmission of audio packets is attempted, then packet loss is reduced, but RF environment of other devices is negatively affected and time slot is continuously occupied

Engineering Contradiction:

Solution Approach 1:

The patent applies dynamics by making the packet data configuration adjustable and adaptive. The system dynamically changes transmission parameters such as packet size, retransmission rate, and frame rate based on real-time communication state detection, allowing the system to respond to changing RF conditions and balance reliability with minimal interference to other devices.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by modifying packet data configurations including packet size, retransmission rate, and frame rate. The controller adjusts these parameters based on detected communication states (good, worse, bad, very bad), transforming the static transmission parameters into dynamic variables that adapt to RF conditions to reduce harmful effects on other devices while maintaining audio quality.

Inventive Principle:
