Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional microphones are used in video conferences with many participants, then the system can capture audio from the space, but it cannot accurately identify the sound source location and corresponding individual
Solution Approach 1:
The patent combines audio information acquisition and video information acquisition into a unified audio and video control system. The system integrates microphone arrays for audio capture with cameras for video capture, and uses a centralized control module to process both audio attributes (direction of arrival, sound pressure level) and video attributes (character position, image proportion) to identify the corresponding relationship between sound sources and individuals.
Solution Approach 2:
The patent introduces an audio and video control system as an intermediary that processes audio information and video information separately before correlating them. The system uses audio attributes including direction of arrival and sound pressure level as intermediate parameters to match with video attributes such as character position and image proportion, thereby identifying the sound source location without requiring direct complex interaction between microphones and camera targets.
2Measurement precision
If the system monitors all participants in real-time, then it can identify sound sources accurately, but the time consumption for processing increases
Solution Approach 1:
The patent applies local quality by focusing processing resources on the most relevant audio and video data. Instead of uniformly processing all audio signals and video frames with equal complexity, the system prioritizes analysis of audio attributes (direction of arrival, sound pressure level) and video attributes (character position, image proportion) based on their relevance to sound source identification, reducing unnecessary computational overhead.
Solution Approach 2:
The patent changes the parameters used for sound source identification from comprehensive multi-dimensional analysis to focused analysis of key parameters. By utilizing specific audio attributes (direction of arrival, sound pressure level) and video attributes (character position, image proportion) as primary identification parameters, the system achieves accurate sound source localization with reduced processing time compared to analyzing all possible audio and video parameters.
3Adaptability or versatility
If the microphone system is designed for fixed positions, then the structure is simple, but it cannot adapt to different spatial environments and moving participants
Solution Approach 1:
The patent implements dynamics by enabling the audio and video control system to adapt to changing spatial environments and moving participants. The system continuously monitors audio attributes including direction of arrival and sound pressure level, and video attributes including character position and image proportion, and dynamically adjusts its processing to track moving sound sources and maintain accurate identification regardless of participant movement or environmental changes.
Solution Approach 2:
The patent creates a universal audio and video control system that can function in various spatial environments and configurations. The system uses multiple audio attributes (direction of arrival, sound pressure level) and video attributes (character position, image proportion) that can be applied across different meeting room layouts, participant arrangements, and environmental conditions, making the system versatile without requiring environment-specific customization.
