Engineering Contradiction Analysis
1Productivity
If traditional volume adjustment methods are used, then the terminal device can play audio sources, but the volume adjustment efficiency is low and power consumption is excessive
Solution Approach 1:
The patent implements dynamic volume adjustment by continuously monitoring audio amplitude and automatically adjusting volume in real-time based on the actual audio characteristics, replacing static traditional volume control methods. This dynamic adaptation improves adjustment efficiency while optimizing power consumption by only adjusting when necessary.
Solution Approach 2:
The system performs self-adjustment of volume by automatically detecting audio amplitude and applying appropriate adjustment coefficients without requiring continuous user intervention. The terminal device serves itself by autonomously optimizing playback parameters, reducing both adjustment overhead and power consumption.
2Ease of operation
If volume is adjusted without considering audio amplitude, then the operation is simple, but the listening experience is suboptimal
Solution Approach 1:
The system incorporates feedback mechanisms by detecting audio amplitude and using this information to automatically adjust volume. The feedback loop ensures that volume adjustments are based on actual audio characteristics, improving listening experience quality while maintaining operational simplicity through automation.
Solution Approach 2:
The patent replaces manual mechanical volume adjustment with an automated electronic control system that uses audio amplitude detection and coefficient-based adjustment. This substitution eliminates the need for user judgment and manual tweaking, maintaining ease of operation while significantly improving reliability of the listening experience.
3Device complexity
If fixed volume adjustment is applied, then the control is straightforward, but it does not adapt to changing audio amplitudes or user preferences
Solution Approach 1:
The system dynamically changes the volume parameter based on detected audio amplitude characteristics. By adjusting the volume parameter in response to varying audio conditions, the system achieves adaptability without requiring complex control logic, as the adjustment rules are based on straightforward amplitude threshold comparisons.
Solution Approach 2:
The patent transforms fixed volume control into a dynamic system that adapts to changing audio amplitudes and playback conditions. The volume adjustment coefficient is dynamically selected based on real-time audio analysis, enabling the system to adapt to varying audio characteristics while maintaining relatively simple control mechanisms.
