Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cloud-based separation models are used for track separation, then processing capability is improved, but real-time performance and flexibility are worsened
Solution Approach 1:
The patent extracts the track separation functionality from cloud-based processing and implements it locally within the playback device. The audio separation module is integrated into the device itself, allowing track separation to be performed on-device without uploading audio signals to cloud platforms, thereby eliminating network delays and enabling real-time processing.
Solution Approach 2:
The patent introduces an intermediate local processing layer between the audio source and the user. The playback device serves as an intermediary that performs track separation locally using integrated separation models, rather than directly relying on cloud-based processing, thus reducing latency while maintaining separation quality.
2Device complexity
If ordinary separation models are used, then device complexity is reduced, but track separation capability and user experience are worsened
Solution Approach 1:
The patent implements a universal audio separation module that can separate audio signals into multiple independent tracks (vocals, drums, bass, guitar, etc.) simultaneously. This multi-functional module replaces the need for multiple specialized separation models, providing comprehensive track separation capability while maintaining manageable device complexity through integration.
Solution Approach 2:
The patent segments the audio signal into multiple independent frequency bands and process each band separately through the audio separation module. This segmentation approach allows detailed track separation across different frequency ranges while keeping the overall system architecture organized and manageable.
3Measurement precision
If cloud-based processing is used, then separation quality can be improved, but operational flexibility and ease of use are worsened
Solution Approach 1:
The playback device performs track separation autonomously using its integrated audio separation module. The device processes audio signals locally without requiring user intervention to upload files to cloud platforms or wait for remote processing, thereby simplifying the user workflow and improving ease of operation while maintaining separation quality.
Solution Approach 2:
The patent merges the audio separation functionality directly into the playback device, combining the separation module with the playback architecture. This integration eliminates the need for separate cloud-based processing steps, allowing users to simply play audio and receive instantly processed output with separated tracks, greatly improving operational flexibility.
4Productivity
If track separation is performed in real-time locally, then flexibility and real-time performance are improved, but device complexity and computational requirements are worsened
Solution Approach 1:
The patent implements a nested architecture where the audio separation module is integrated within the playback device's existing signal processing pipeline. The separation functionality is embedded within the audio processing chain, allowing real-time processing without requiring a completely separate system, thus managing device complexity through hierarchical integration.
