Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lens array component is used to enable oblique viewing and mid-air floating images, then the stereoscopic image display capability is improved, but the manufacturing cost increases and image quality degrades due to aberrations
Solution Approach 1:
The patent removes the lens array component from the display system entirely. Instead of using lenses to control light direction, the invention uses a light field adjustment layer with microlenses combined with specific image rendering algorithms to achieve oblique viewing capability without the aberrations and manufacturing complexities of traditional lens arrays
Solution Approach 2:
The patent replaces the mechanical optical system (lens array) with a combination of a light field adjustment layer and computational image processing. The light field adjustment layer uses an array of microlenses on a transparent substrate, and the image algorithm unit processes images to account for the optical characteristics, substituting complex mechanical lens arrangements with a simpler layered structure配合算法
2Adaptability or versatility
If a lens array component is used to display stereoscopic images, then the 3D visualization effect is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent segments the display system into distinct functional layers: a display panel, a light field adjustment layer with microlenses, and an image algorithm unit. This segmentation allows each component to be optimized independently and simplifies manufacturing compared to integrated lens array systems
Solution Approach 2:
The patent extracts and removes the problematic lens array component from the system. The light field adjustment layer uses a transparent substrate with microlenses that can be applied as a separate layer, eliminating the need for complex integrated lens array manufacturing
3Area of stationary object
If a lens array component is used for large size applications, then the display area can be increased, but incorrect images appear at large viewing angles and image quality cannot be improved
Solution Approach 1:
The patent changes the optical parameters by using a light field adjustment layer with controllable microlens characteristics rather than fixed lens array parameters. The image algorithm unit dynamically adjusts image rendering based on viewing angle and position, allowing large display areas to maintain image quality across different viewing conditions
Solution Approach 2:
The patent replaces the mechanical lens array system with a light field adjustment layer combined with computational image processing. This substitution allows for larger display areas without the geometric limitations and image quality degradation that occur with traditional lens arrays at oblique viewing angles
4Adaptability or versatility
If a lens array component is used to enable mid-air floating images, then the visual immersion is improved, but the manufacture cost increases
Solution Approach 1:
The patent removes the expensive lens array component and replaces it with a light field adjustment layer consisting of a transparent substrate with microlenses. This layer can be manufactured more simply and applied to the display panel, reducing costs while maintaining the mid-air floating image effect through coordinated image rendering
Solution Approach 2:
The patent uses a light field adjustment layer that can be replicated and applied to display panels of various sizes. The microlens array on the transparent substrate can be manufactured using standard techniques and applied as a separate layer, making the technology more cost-effective than custom-integrated lens array systems
