Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pixels are viewed through lenses in a VR display system, then a sense of virtual reality is achieved, but visibility and image clarity are reduced
Solution Approach 1:
The patent applies local quality by making the scan lines and signal lines non-parallel and non-orthogonal to each other, creating a specific angular relationship that optimizes the display characteristics when viewed through lenses. This local geometric adjustment in the pixel arrangement improves visibility and reduces the screen-door effect specifically in the lens-viewing context without affecting other aspects of the display system
Solution Approach 2:
The patent introduces asymmetry by arranging scan lines and signal lines at non-orthogonal angles, breaking the conventional orthogonal grid structure. This asymmetric arrangement optimizes the optical path and pixel visibility when viewed through VR lenses, enhancing image clarity while maintaining the virtual reality effect
2Ease of manufacture
If conventional orthogonal pixel arrangement is used, then manufacturing is simplified, but screen-door effects and distortion are increased when viewed through lenses
Solution Approach 1:
The patent replaces the symmetric orthogonal grid arrangement with an asymmetric non-orthogonal arrangement of scan lines and signal lines. This asymmetric design specifically addresses and reduces the screen-door effect and distortion when viewed through VR lenses, while the overall manufacturing process remains relatively simple and compatible with existing fabrication techniques
3Device complexity
If scan lines and signal lines are arranged orthogonally, then device structure is simplified, but visibility through lenses is reduced
Solution Approach 1:
The patent applies local quality by optimizing the angular relationship between scan lines and signal lines specifically for lens viewing. The non-parallel and non-orthogonal arrangement creates favorable optical characteristics in the specific context of VR display through lenses, improving visibility without significantly increasing overall device complexity
Solution Approach 2:
The patent introduces dynamic optimization by adjusting the angular parameters of scan lines and signal lines based on the specific viewing conditions through lenses. The non-fixed angular relationship allows for optimized visibility across different viewing angles and lens positions, enhancing the overall user experience
