Engineering Contradiction Analysis
1Illumination intensity
If the resonance space is increased to improve audio quality, then sound output quality is improved, but the device volume increases
Solution Approach 1:
The patent implements nested enclosures where a first enclosure containing the speaker is placed within a second enclosure, creating multiple resonating spaces at different levels. This nested structure allows the device to achieve enhanced audio quality through multiple resonating chambers without proportionally increasing the overall device volume, as the enclosures share space efficiently.
Solution Approach 2:
The patent utilizes vertical stacking of enclosures (first enclosure and second enclosure arranged in different spatial dimensions) to create additional resonating space. By transitioning from a single-plane resonance chamber to a multi-dimensional stacked configuration, the device achieves increased resonance volume without linearly expanding the device footprint in all directions.
2Productivity
If multiple adsorption sheets are added to optimize resonance, then audio efficiency is improved, but device complexity increases
Solution Approach 1:
The patent divides the resonance management function into multiple discrete adsorption sheets placed at different locations within the enclosures. Each adsorption sheet independently manages acoustic properties in its local region, allowing for optimized audio efficiency through distributed acoustic control. This segmentation enables fine-tuned resonance optimization without requiring a completely complex integrated system.
Solution Approach 2:
The adsorption sheets serve as intermediary elements between the speaker and the resonating air columns. These sheets mediate the acoustic interaction by selectively absorbing and releasing air molecules, thereby optimizing resonance without requiring direct complex mechanical or electronic control systems. The intermediary sheets simplify the overall system complexity while achieving sophisticated acoustic performance.
