Engineering Contradiction Analysis
1Length of moving object
If conventional structural design is used for display devices, then manufacturing and assembly are simplified, but the device cannot achieve a slim form factor while maintaining effective heat dissipation and optical performance
Solution Approach 1:
The patent merges the bottom chassis and heat dissipation structure into a single integrated component. The bottom chassis is designed with an integrated heat dissipation structure that includes a heat source accommodating portion, heat dissipation channels, and heat radiation portions, eliminating the need for separate heat dissipation components and reducing overall device thickness while maintaining effective heat management
Solution Approach 2:
The bottom chassis serves multiple functions simultaneously: it provides structural support, facilitates heat dissipation through integrated channels and radiation portions, and accommodates light sources. This multi-functional design reduces the number of separate components needed, achieving a slim profile without compromising thermal or optical performance
2Ease of manufacture
If multiple separate components are used for bottom chassis, light source unit, and heat dissipation structure, then assembly and manufacturing are easier, but the overall device size increases and heat dissipation efficiency decreases
Solution Approach 1:
The bottom chassis is designed as an integrated structure combining support, heat dissipation, and light source accommodation functions. The heat dissipation structure includes heat dissipation channels formed within the bottom chassis itself and heat radiation portions that extend toward the display panel, creating efficient thermal pathways without requiring separate heat dissipation components
Solution Approach 2:
The bottom chassis features localized heat dissipation structures positioned strategically near heat-generating components. The heat radiation portions are specifically positioned to face the display panel, and the heat dissipation channels are configured to efficiently conduct heat away from light sources, optimizing thermal management at critical locations
3Reliability
If conventional bottom chassis design is used, then manufacturing is simpler, but the device cannot achieve effective heat dissipation and optical performance for curved displays
Solution Approach 1:
The bottom chassis integrates multiple functions including structural support, heat dissipation through embedded channels, and light source accommodation. The heat dissipation structure is formed as an integral part of the bottom chassis, with heat dissipation channels and radiation portions that work together to efficiently manage thermal loads while supporting the display panel and backlight unit
Solution Approach 2:
The bottom chassis is designed with distinct functional zones: a heat source accommodating portion for light sources, heat dissipation channels for thermal management, and heat radiation portions for heat release. This segmentation of functions within an integrated structure allows for optimized performance of each function while maintaining manufacturing feasibility through unified construction
