Innovation Solution
A sound-controlled gas control system that includes an audio module for preprocessing audio data, a transformation analysis module for Fourier transformation and spectrum analysis, and a driving module to generate pulse width modulation data for controlling proportional valves, reducing spectrum leakage through windowing processes and using amplitude and phase values to adjust flame height and speed in sync with music.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If discrete audio data is directly converted to control signals without preprocessing, then the system structure is simple, but spectrum leakage occurs and flame rhythm effect is poor
Solution Approach 1:
The patent applies preliminary action by performing windowing processing on audio data before Fourier transformation. This preprocessing step prepares the data in advance to prevent spectrum leakage, ensuring that the flame rhythm synchronization quality is improved without adding complex hardware, only by adding computational steps in the signal processing chain.
2Reliability
If Fourier transformation and spectrum analysis are performed on audio data, then flame rhythm effect is improved, but computation time and processing complexity increase
Solution Approach 1:
The patent extracts only the necessary frequency components from the audio spectrum through spectrum analysis. By identifying and processing only the relevant frequency ranges that correspond to musical rhythms, the system achieves good flame synchronization quality while reducing unnecessary computational overhead and processing time.
3Adaptability or versatility
If multiple frequency segments are analyzed with multiple proportional valves, then flame rhythm effect is enriched, but system complexity increases
Solution Approach 1:
The patent segments the audio frequency spectrum into multiple frequency bands, each controlled by a separate proportional valve. This segmentation allows different parts of the audio signal to control different flame characteristics, enriching the rhythm effect while maintaining a modular control structure that manages complexity through functional decomposition.
