Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple drive chips are mounted on the display board to achieve lower pitch and higher luminance, then display performance is improved, but heat generation increases
Solution Approach 1:
The patent combines the heat radiation function and audio output function into a single integrated structure. The heat radiation plate serves dual purposes: radiating heat from the drive chips and supporting the audio device, thereby managing thermal load while enabling sound output without requiring separate components
Solution Approach 2:
The heat radiation plate is designed as a multi-functional component that simultaneously performs heat dissipation and audio signal transmission. By fixing the audio device to the heat radiation plate, the system achieves both thermal management and audio output through a single structural element, reducing overall system complexity
2Illumination intensity
If multiple drive chips are mounted on the display board to achieve lower pitch and higher luminance, then display performance is improved, but device complexity increases
Solution Approach 1:
The patent merges the heat radiation plate and audio device into a unified assembly. Instead of treating heat management and audio output as separate subsystems, the invention integrates them by fixing the audio device directly to the heat radiation plate, thereby simplifying the overall structure while supporting high-performance drive chip configurations
