Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a component area is arranged in the display area to integrate sensors or cameras, then functionality is expanded, but light transmittance deteriorates and image quality deteriorates
Solution Approach 1:
The display area is segmented into pixel areas and transmission areas, allowing different functional zones within the same display region. This enables components to be placed in transmission areas while maintaining display functionality in pixel areas, thus expanding functionality without completely blocking light transmission paths.
Solution Approach 2:
Different areas of the display are given different properties: pixel areas contain display elements for image output, while transmission areas are optimized for light transmission to allow component integration. This local differentiation allows functionality expansion in transmission areas without compromising light transmittance in pixel areas.
2Adaptability or versatility
If a component area is arranged in the display area to integrate sensors or cameras, then functionality is expanded, but image quality deteriorates
Solution Approach 1:
By segmenting the display area into distinct pixel and transmission zones, the patent isolates component placements to specific transmission areas. This prevents components from interfering with the uniformity and quality of displayed images in pixel areas, maintaining image quality while enabling functionality expansion.
Solution Approach 2:
The transmission area acts as an intermediary zone between the component layer and the display output. Components are placed in this intermediate transmission area, which allows light and signals to pass through with minimal interference, thus maintaining image quality while enabling component integration.
3Adaptability or versatility
If the display area is expanded to include transmission areas, then design flexibility is improved, but device complexity increases
Solution Approach 1:
The patent merges the display function and component integration function into a single display area by creating transmission areas within it. This unified structure eliminates the need for separate component housings or additional structural elements, thereby increasing design flexibility without proportionally increasing device complexity.
Solution Approach 2:
The transmission areas serve multiple functions: they allow light transmission for display visibility, provide space for component placement, and maintain structural integration with the rest of the display. This multi-functionality reduces the need for additional separate structures, balancing design flexibility with manageable complexity.
