Audio Dongle Dual-Mode Pairing and Wireless Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio communication systems face challenges in pairing speaker devices with dongles, requiring complex software-driven processes and often failing to provide sufficient bandwidth and compatibility, leading to inefficient voice communication and limited control functionalities.
Innovation Solution
An audio communication system comprising a speaker device and a dongle, where the dongle operates in two modes: pairing mode for secure connection with the speaker device and operating mode for wireless communication with external devices, enabling easy pairing and control functionalities like call management without the need for proprietary software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate dongle is used for wireless communication with the headset, then bandwidth and compatibility for audio streaming are improved, but device complexity increases
Solution Approach 1:
The patent introduces a dongle as an intermediary device between the headset and the host device. The dongle contains a wireless transceiver that communicates with the headset using proprietary protocols, while its USB interface communicates with the host device. This intermediary resolves the contradiction by providing dedicated audio streaming bandwidth through the wireless link while maintaining compatibility through the standard USB interface, avoiding the need to modify either the headset or host device.
2Reliability
If a pairing process using dedicated software is implemented, then connection reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements self-service by enabling the dongle to automatically perform pairing and connection establishment with the headset without requiring user intervention or dedicated software. The dongle's microcontroller automatically initiates the pairing process when the headset is placed in pairing mode, exchanges necessary information, and establishes the wireless connection autonomously. This resolves the contradiction by maintaining reliable connections through automated procedures while greatly improving ease of operation.
Solution Approach 2:
The patent applies preliminary action by pre-programming the dongle with the necessary pairing information and protocols during manufacturing. The dongle is pre-paired with the headset or pre-configured to automatically initiate pairing when needed. This preliminary preparation eliminates the need for complex runtime pairing processes, achieving both reliable connections and ease of operation.
