Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If polarizers and polarized glasses are added to achieve three-dimensional display, then three-dimensional viewing effect is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts and removes the polarizer components from the display system. Instead of using polarized light separation, the system directly renders different images for left and right eyes through software processing and head tracking, eliminating the need for physical polarizing filters and polarized glasses, thus reducing device complexity while maintaining three-dimensional viewing effect
Solution Approach 2:
The patent replaces the optical mechanical system (polarizers and polarized glasses) with a computational system. Head position and orientation are detected via sensors, and projection images are dynamically adjusted through software rendering algorithms, substituting physical optical components with electronic detection and computational processing
2Reliability
If polarized glasses are required for three-dimensional display, then three-dimensional viewing effect is improved, but ease of operation deteriorates
Solution Approach 1:
The system provides self-service three-dimensional display by automatically detecting head position and orientation through onboard sensors, and dynamically adjusting projection images without requiring the user to wear any auxiliary devices. The display adapts to the user's natural viewing position, making operation as easy as looking at the screen while maintaining three-dimensional effect
3Manufacturing precision
If multiple projection images are rendered for different eye positions, then three-dimensional display accuracy is improved, but calculation pressure increases
Solution Approach 1:
The patent implements partial action by detecting head orientation to determine a limited field of view region, and only rendering projection images for that specific region rather than the entire display area. This selective rendering approach maintains three-dimensional display accuracy for the relevant viewing area while significantly reducing calculation pressure and energy consumption compared to full-screen multi-position rendering
