Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If binocular disparity scheme is used to form 3D image, then 3D visualization is achieved, but viewer experiences dizziness and fatigue
Solution Approach 1:
The patent replaces the binocular disparity scheme (which creates harmful stereoscopic effects) with a digital holographic approach that uses optical interference patterns. This substitution eliminates the need for artificial depth cues that cause viewer discomfort while maintaining genuine 3D visualization capabilities through wavefront reconstruction.
Solution Approach 2:
The patent changes the fundamental parameters of 3D image formation from binocular disparity (difference in images between two eyes) to holographic interference patterns (optical wave superposition). This parameter change transforms the mechanism from one that creates artificial depth perception to one that reconstructs actual light fields, eliminating viewer fatigue.
2Productivity
If computer-generated hologram processing is used to generate digital holographic content in real time, then 3D image generation is achieved, but processing capability is limited
Solution Approach 1:
The patent segments the complex CGH processing into distinct functional modules: 3D model acquisition unit, hologram generation unit (with Fresnel/Kirchhoff diffraction calculations), editing unit, and restoration unit. This segmentation allows each module to be optimized independently and processed through a pipeline architecture, improving real-time performance while managing complexity.
Solution Approach 2:
The patent implements preliminary action by pre-calculating diffraction patterns using Fresnel or Kirchhoff approximations, pre-processing 3D model data, and preparing holographic content in advance. This allows the system to reduce real-time processing requirements and manage computational complexity more effectively.
3Manufacturing precision
If digital holographic content is processed through multiple separate steps (acquisition, generation, editing, restoration), then comprehensive content processing is achieved, but process efficiency is reduced
Solution Approach 1:
The patent merges the separate processing steps (acquisition, generation, editing, restoration) into an integrated digital holographic content processing system with a unified pipeline architecture. The process management unit coordinates all steps through standardized interfaces, maintaining comprehensive processing capability while improving efficiency through streamlined workflow and resource sharing.
Solution Approach 2:
The patent implements continuous processing through a pipeline architecture where output from one unit immediately becomes input to the next unit without interruption. The process management unit ensures continuous flow of data through acquisition, generation, editing, and restoration stages, eliminating idle time and improving overall processing efficiency while maintaining complete functional capability.
