Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sound output devices output sound in complex environments with multiple sound sources, then the device can provide comprehensive audio information, but the user experience deteriorates due to inability to clearly distinguish between external and device-generated sounds
Solution Approach 1:
The patent segments the sound field into external sound components and device-generated sound components. The external sound processing unit separately processes sounds from the external environment, while the device-generated sound processing unit handles sounds produced by the device. This segmentation allows the system to maintain comprehensive audio information while enabling clear distinction between different sound sources through spatial separation and independent processing channels.
2Quantity of substance
If the device outputs all sounds simultaneously without adjustment, then complete audio information is provided, but speech recognition accuracy deteriorates due to sound interference
Solution Approach 1:
The patent implements dynamic adjustment of sound output characteristics based on real-time environmental conditions. The controller continuously monitors the acoustic environment and dynamically adjusts parameters such as volume, spatial position, and timing of device-generated sounds relative to external sounds. This dynamic control enables the system to optimize speech recognition accuracy by adapting sound output to current conditions while maintaining complete audio information availability.
3Device complexity
If the device uses traditional sound output methods without prediction capability, then the system complexity is low, but the user experience deteriorates in environments with predictable sound patterns
Solution Approach 1:
The patent incorporates sound prediction functionality that analyzes external sound patterns and predicts future sound events. By predicting upcoming sounds such as speech inputs or environmental noises, the system can proactively adjust device-generated sound output in advance. This preliminary action enables better environmental adaptation and user experience without requiring excessively complex real-time processing, as the system prepares sound adjustments based on predicted scenarios.
