Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional components are added to display 3D images, then 3D display capability is improved, but device complexity and thickness increase
Solution Approach 1:
The patent combines multiple functional components (color filters for left and right eyes, disparity barrier patterns) into a single integrated display structure. The color filters and disparity barrier patterns are formed on the same substrate, merging what would traditionally be separate components into one unified system, thereby achieving 3D display capability without proportionally increasing device complexity
Solution Approach 2:
The patent utilizes the spatial dimension by forming color filters and disparity barrier patterns at different locations (front and back surfaces of the substrate) to create distinct optical paths for left and right eyes. This dimensional arrangement enables 3D display functionality by separating images in space rather than requiring separate physical components for each eye
2Adaptability or versatility
If additional components are added to display 3D images, then 3D display capability is improved, but device thickness and weight increase
Solution Approach 1:
The patent embeds multiple functional layers (color filters, disparity barrier patterns) within a single substrate structure. The front color filters, back color filters, and disparity barrier patterns are nested within the same physical component, allowing multiple functions to be achieved without proportionally increasing overall device thickness
Solution Approach 2:
The patent arranges color filters and disparity barrier patterns on opposite surfaces of the substrate, utilizing the thickness dimension efficiently. By spacing these components apart along the optical path rather than stacking them laterally, the design achieves 3D functionality while minimizing increases in overall device thickness
3Ease of manufacture
If color filters and disparity barrier pattern are integrated, then manufacturing simplicity is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent forms the disparity barrier patterns and color filters during the same manufacturing process step, establishing their relative positions beforehand. By creating both patterns simultaneously or in sequence on the same substrate, the design ensures precise alignment without requiring complex post-manufacturing adjustment procedures
Solution Approach 2:
The substrate structure itself provides the alignment reference for color filters and disparity barrier patterns. The physical geometry of the substrate and the relative positioning of patterns on its surfaces create self-aligning features that maintain precise optical relationships without requiring external alignment mechanisms or complex assembly procedures
