Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sound spectrum information is analyzed and calculated in real-time on mobile platforms, then the ability to generate detailed and diverse special effect animations is improved, but the computational limitations and processing power constraints of mobile platforms cause analysis failures and incomplete data extraction
Solution Approach 1:
The patent applies preliminary action by pre-calculating sound spectrum information from audio files during the asset creation phase, storing the computed spectrum data in image files. This allows the game client to directly load and use pre-processed spectrum information without performing computationally intensive real-time Fourier transforms on mobile devices, thereby ensuring both extraction accuracy and analysis reliability on resource-constrained platforms.
2Loss of information
If Fourier transform is performed to convert time domain information into frequency domain information for music waveform spectrum, then the ability to present music waveform spectrum is improved, but the computational complexity and processing time increase significantly on mobile platforms
Solution Approach 1:
The patent resolves this contradiction by performing the computationally intensive Fourier transform operation in advance during audio file processing, storing the resulting frequency domain spectrum information in image format. This preliminary computation eliminates the need for real-time Fourier transforms on mobile devices, maintaining complete spectrum information while drastically reducing computational complexity and processing time on resource-constrained platforms.
3Adaptability or versatility
If sound spectrum information is stored in color channels of picture or video files, then the ability to generate special effect animations is improved, but the data structure complexity and file format requirements increase
Solution Approach 1:
The patent applies the color changes principle by mapping sound spectrum data to color channel values in image files. The amplitude spectrum information is encoded in the RGB color channels, allowing spectrum data to be stored using standard image file formats. This approach enables versatile special effect animation generation while avoiding the need for custom data structures or specialized file formats, as the spectrum information is embedded within conventional image files using color encoding.
