Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components such as sensors or cameras are integrated into the display area, then the functionality of the display apparatus is enhanced, but the display area is reduced
Solution Approach 1:
The patent integrates components into the display area by transitioning from a two-dimensional plane to a three-dimensional structure. Components are positioned in a third dimension (below or above the display surface) while maintaining alignment with the display area, allowing both component integration and full display area utilization.
Solution Approach 2:
The patent embeds components within the display structure by nesting them in layers below or above the active display area. The components are contained within the overall display apparatus structure, allowing multiple functions to coexist in a compact integrated design where components are nested within the display area boundaries.
2Adaptability or versatility
If a transmission area is added to allow component integration, then component integration is enabled, but the structural complexity increases
Solution Approach 1:
The transmission area serves multiple functions simultaneously: it allows light transmission for display purposes, provides a pathway for component integration, and enables optical access to components. This multi-functional design reduces the need for separate dedicated areas for each function, thereby managing structural complexity while enabling component integration.
Solution Approach 2:
The patent applies different properties to different regions of the display area. The transmission area has optimized optical properties (higher transmittance) compared to the pixel area, allowing local optimization for component integration while maintaining overall display functionality. This localized approach enables component integration without requiring complete structural redesign.
3Illumination intensity
If a hydrophobic layer with fine particles is used to enhance light transmission, then light transmission is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent optimizes parameters of the hydrophobic layer including particle size distribution, concentration, and material composition to achieve high light transmission. By carefully controlling these parameters within specific ranges, the system achieves enhanced optical performance while maintaining manufacturability through standard fabrication processes.
Solution Approach 2:
The hydrophobic layer is constructed as a composite material combining fine particles with a matrix material. This composite structure provides both the hydrophobic properties needed for particle stability and the optical properties needed for light transmission. The composite nature allows tuning of properties to balance optical performance with manufacturing feasibility.
