Wireless Speaker Error Reporting After Forced Shutdown
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio devices, such as wireless speakers, suffer from unexplained shutdowns due to fatal errors, with the cause often unknown to the user, making it difficult to identify appropriate solutions.
Innovation Solution
An audio system comprising an audio device, a wireless terminal, and a solution providing server that monitors errors and provides an error report, switching power supply from a backup power supply, and a solution providing server that provides a solution to errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the audio device provides detailed error information to help users identify solutions, then the ease of operation is improved, but the device complexity increases due to additional monitoring and reporting mechanisms
Solution Approach 1:
The audio device automatically monitors its own operational status, detects errors, generates error reports containing detailed information, and transmits this information to the wireless terminal without requiring user intervention. This self-service mechanism enables the device to provide detailed error information autonomously, improving ease of operation while the automation handles the complexity internally
Solution Approach 2:
The wireless terminal acts as an intermediary between the audio device and the solution providing server. It receives error reports from the audio device, transfers them to the server, and presents solutions to the user. This intermediary role allows the audio device to maintain simplicity while still providing detailed error information through the terminal's mediation
2Reliability
If the audio device switches to backup power supply to ensure continuous operation during error, then the reliability is improved, but the loss of energy increases due to backup power consumption
Solution Approach 1:
The audio device is equipped with a backup power supply that remains on standby before errors occur. When an error is detected, the system switches to the backup power supply to ensure continuous operation, preventing shutdown. This beforehand cushioning improves reliability by having emergency power ready, while the backup power is only activated when needed, minimizing overall energy loss compared to continuous operation failures
3Adaptability or versatility
If the system collects and stores detailed error information and solution data, then the adaptability is improved for providing accurate solutions, but the volume of data storage increases
Solution Approach 1:
The solution providing server extracts and stores only the essential error information and corresponding solutions in a structured table format. By taking out only the necessary data elements (error details, model name, software version, and solutions) rather than storing all possible device information, the system achieves adaptability for accurate solution matching while minimizing data storage volume requirements

AI summary
[Problem] To provide a technology that makes it possible to suggest appropriate solutions to errors associated with the forced shutdown of an audio device. [Solution] Upon detecting an error caused by a forced shutdown, a wireless speaker 1-1-1-n switches a power supply supply source from a principal power supply to a backup power supply, transmits an error report that includes error details for the detected error, a model name, and version information for installed software to a wireless terminal 2, and shuts down. The wireless terminal 2 forwards the error report received from the wireless speaker 1-1-1-n to a solution provision server 4, receives a solution from the solution provision server 4, and presents the solution. The solution provision server 4 finds a solution that corresponds to the error details included in the error report received from the wireless terminal 2 from a table associated with the model name and the version information for the installed software included in the error report and transmits the solution found to the wireless terminal 2.
