Innovation Solution
An electronic apparatus and method that includes a control module to store and retrieve setting information for different audio languages, formats, and input sources, allowing automatic adjustment of audio output levels based on user settings, eliminating the need for manual volume adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual volume adjustment is used for each audio signal, then the user can precisely control the volume, but the operation becomes complex and time-consuming when switching between multiple audio signals
Solution Approach 1:
The system performs preliminary actions by automatically adjusting the volume of each audio signal based on pre-stored reference volume information before the user needs to use it. When an audio signal is selected, the corresponding volume is automatically set according to the stored reference data, eliminating the need for manual adjustment each time.
Solution Approach 2:
The volume adjustment system serves itself by automatically selecting and applying the appropriate volume level for each audio signal based on stored reference information. The system performs the volume adjustment function autonomously without requiring user intervention, thus resolving the contradiction between ease of operation and time consumption.
2Ease of operation
If manual volume adjustment is required for each audio signal change, then the user maintains control over audio levels, but the device complexity increases
Solution Approach 1:
The system achieves self-service by automatically managing volume adjustments based on stored reference volume information for different audio signals. This automation simplifies the user interface and operation while the backend system handles the complexity of managing multiple audio signal volumes, effectively resolving the contradiction between ease of operation and device complexity.
3Productivity
If automatic volume adjustment based on stored settings is implemented, then user intervention is reduced, but the system requires additional storage and control mechanisms
Solution Approach 1:
The system performs preliminary actions by storing reference volume information for multiple audio signals in advance. When an audio signal is selected, the pre-stored reference volume is automatically retrieved and applied, enabling efficient audio signal switching without requiring complex real-time analysis or user intervention, thus resolving the contradiction between productivity and device complexity.
Solution Approach 2:
The system uses copying by storing reference volume information that represents the desired volume state for each audio signal. Instead of implementing complex real-time volume optimization algorithms, the system copies and applies pre-determined volume settings from storage, achieving high productivity with minimal additional system complexity.
