Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hollow-out area is added to the back plate for external device integration, then the versatility of the display panel is improved, but the structural complexity increases
Solution Approach 1:
The backlight module is segmented into a light transmissive area and a light emitting area, allowing different functional zones within the same module. This segmentation enables the hollow-out area to be integrated without requiring a completely separate structure, thus improving versatility while controlling complexity
Solution Approach 2:
The back plate with hollow-out area is designed to accommodate multiple functions: it serves as the structural base plate, provides mounting for external devices through the hollow-out area, and maintains backlight functionality through the light transmissive area. This multi-functionality approach improves versatility without proportionally increasing structural complexity
2Adaptability or versatility
If the backlight module is divided into light transmissive area and light emitting area, then the display functionality is improved, but the manufacturing precision requirements increase
Solution Approach 1:
Different areas of the backlight module are assigned different optical properties: the light transmissive area allows light passage for transparent display, while the light emitting area provides illumination for conventional display. This local differentiation enables diverse display functionality while using standardized manufacturing processes for each zone, thereby controlling precision requirements
3Adaptability or versatility
If the panel is configured with display area and transparent area, then the multifunctional display capability is improved, but the device complexity increases
Solution Approach 1:
The display panel integrates both conventional display functionality (display area) and transparent display functionality (transparent area) within a single panel structure. By merging these functions into one unified device rather than requiring separate panels, the multifunctional capability is improved while the overall device complexity is managed through integration
