Networked Amplifier Output Monitoring for Sound Stoppage Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio devices lack the ability to predict and prevent sound stoppages, with existing technologies not providing a method to detect potential issues from outside the device.
Innovation Solution
An audio device equipped with a network interface, amplifier, and processor that sends output values of the amplifier through the network interface, allowing external analysis to predict potential problems, such as unusual voltage or current values, which may indicate sound stoppages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio device operates without external monitoring, then device complexity is reduced, but reliability deteriorates due to inability to predict sound stoppages
Solution Approach 1:
The patent introduces an external server as an intermediary that receives output values from the amplifier via network interface. The server performs the analysis and prediction of sound stoppages, rather than requiring complex monitoring systems within the audio device itself. This transfers the computational burden to an external system.
Solution Approach 2:
The audio device sends its own operational data (output values) through the network interface for external analysis. The device essentially monitors itself by making its data available externally, without requiring internal monitoring hardware or processing capabilities.
2Measurement precision
If output values are sent through network interface, then measurement precision is improved for predicting problems, but loss of time increases due to data transmission
Solution Approach 1:
The system continuously transmits output values from the amplifier to the server without interruption. This continuous data flow ensures that the latest operational state is always available for analysis, minimizing detection delays while maintaining precise monitoring of the audio device's condition.
