Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If real-time image analysis is performed at high frequency to detect user position and adjust audio, then audio adaptation to user situation is improved, but energy consumption increases significantly
Solution Approach 1:
The patent applies periodic action by capturing images at different frequencies based on detected events. Normal operation uses a lower first image capture frequency to save energy, while event detection (such as user presence detection) triggers a higher second image capture frequency. This periodic variation in processing intensity resolves the contradiction between continuous adaptation and energy consumption.
Solution Approach 2:
The system dynamically adjusts the image capture frequency based on situational context. The audio adjustment module changes operational parameters (image capture frequency) according to detected user situations, transitioning between low-power and high-precision modes. This dynamic adaptation allows the system to maintain audio adaptability while minimizing energy consumption during stable states.
2Use of energy by moving object
If manual audio adjustment is required when user position changes, then energy consumption is reduced, but user experience and convenience deteriorate
Solution Approach 1:
The system performs self-service by automatically detecting user position changes through image analysis and adjusting audio parameters without requiring manual user intervention. The audio adjustment module autonomously responds to detected situations, eliminating the need for users to manually adjust audio settings while maintaining energy efficiency through selective processing.
Solution Approach 2:
The system implements feedback loops where image capture results inform audio adjustment decisions. The audio adjustment module continuously monitors user position through periodic image analysis and automatically adjusts audio output based on detected changes, creating a closed-loop system that improves convenience without requiring manual input while managing energy consumption.

AI summary
An audio control method and an electronic device are disclosed. The method includes: obtaining candidate image data through an image capture device based on a first image capture frequency, wherein the candidate image data presents a head image of a target user; determining a second image capture frequency based on ability information, wherein the ability information reflects an adjustment ability of an audio adjustment module for an output audio, and the second image capture frequency is lower than the first image capture frequency; obtaining target image data from the candidate image data based on the second image capture frequency; processing the target image data through an image analysis module to obtain situational information related to the target user; processing the situational information through the audio adjustment module to obtain an audio adjustment parameter; and adjusting the output audio of an audio output device based on the audio adjustment parameter.
