Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio data transmission technologies in mobile devices often transmit audio data at a fixed rate, which can lead to poor user experience due to insufficient signal strength or increased computing demands, resulting in issues like buffering and skipping.
Innovation Solution
Implementing dynamic rate switching between basic and enhanced data rates based on signal strength and packet error rate, allowing wireless headphones to adjust the transmission rate dynamically to maintain optimal audio quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio data is transmitted at a basic fixed rate, then device compatibility and stability are improved, but audio quality and user experience deteriorate when computing demands increase or signal strength is sufficient
Solution Approach 1:
The patent implements dynamic rate switching that allows the transmission system to adapt between basic and enhanced data rates based on real-time conditions. The mobile device monitors packet error rates and signal strength, then dynamically adjusts the audio data transmission rate accordingly, transitioning from a static basic rate to a dynamic rate that can scale up to enhanced rates when conditions permit, thereby resolving the contradiction between stability and transmission performance
Solution Approach 2:
The system changes the transmission parameter (data rate) based on monitored conditions. When packet error rates are low and signal strength is high, the system switches from basic rate to enhanced rate parameters. This parameter adaptation allows the system to optimize audio quality and throughput without compromising stability when conditions deteriorate, effectively resolving the fixed rate limitation
2Productivity
If audio data is transmitted at an enhanced data rate, then audio quality and user experience are improved, but transmission reliability and stability worsen when signal strength is weak or packet error rates increase
Solution Approach 1:
The patent implements a feedback mechanism where the mobile device continuously monitors packet error rates and signal strength during audio data transmission. Based on this feedback, the system automatically adjusts the transmission rate - switching from enhanced to basic rate when packet error rates exceed thresholds or signal strength deteriorates. This closed-loop control ensures transmission reliability is maintained while maximizing audio quality when conditions allow
Solution Approach 2:
The system dynamically adjusts the data transmission rate based on real-time monitoring of transmission conditions. The mobile device can switch between enhanced and basic rates adaptively, ensuring that high data rates are only used when signal conditions support them, thereby maintaining both audio quality and transmission stability simultaneously through dynamic adaptation
3Device complexity
If a single basic transmission rate is used, then device complexity is reduced and compatibility is improved, but adaptability to different signal conditions and computing demands deteriorates
Solution Approach 1:
The patent enables the transmission system to perform multiple functions by supporting both basic and enhanced data rates within the same device architecture. The mobile device and wireless headphones are designed to handle multiple transmission modes, providing universal compatibility across different signal conditions and device capabilities while maintaining a relatively simple implementation through standardized protocol extensions

AI summary
A wireless headphone that receives a device identifier of an electronic device communicatively coupled to the wireless headphone and determines that the electronic device supports dynamic rate switching between a first data rate and a second data rate. The wireless headphone receives data from the electronic device at the second data rate and determines a packet error rate (PER) value associated with receiving the data. The wireless headphone requests the electronic device to transmit data at the second data rate.
