Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a multi-channel microphone array is embedded in the remote controller to improve speech recognition accuracy, then speech acquisition performance is improved, but device complexity and manufacturing cost increase due to additional ADCs and DSP chips
Solution Approach 1:
The patent combines the speech processing functions of multiple microphones into a unified system where the TV's main processor handles all signal processing tasks. Instead of distributing ADCs and DSP chips across multiple devices, the system merges processing capabilities into a single centralized unit, reducing overall hardware complexity while maintaining multi-channel speech acquisition through the television's built-in microphones.
Solution Approach 2:
The TV set is designed to serve multiple functions: it acts as both the display device and the speech recognition system. The television's existing processor and microphones are utilized for speech processing, eliminating the need for dedicated speech processing hardware in the remote controller. This multi-functional approach reduces device complexity while improving speech recognition capabilities.
2Object-affected harmful factors
If a multi-channel microphone array with separate DSP chip is used to improve speech recognition, then noise removal performance is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges the noise removal processing function into the TV's main processor, eliminating the need for separate DSP chips in each remote controller. By combining speech acquisition and noise removal processing into a single centralized system, the manufacturing cost is reduced while maintaining effective noise removal performance through software-based signal processing.
Solution Approach 2:
Instead of physically embedding multiple microphones and processing chips in each remote controller, the system uses the TV's existing microphones and processor to create a virtual multi-channel speech processing system. This software-based approach copies the functionality of hardware multi-microphone systems without the associated manufacturing costs.
3Measurement precision
If additional hardware components are added to improve speech recognition performance, then recognition accuracy is improved, but power consumption increases
Solution Approach 1:
The patent merges speech processing functions into the TV's main processor, which is already powered and operational. By consolidating speech processing with the television's existing computing resources, the system avoids the additional power consumption that would result from separate DSP chips or microcontrollers in the remote controller, while maintaining high recognition accuracy.
