Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If Snell's law is applied for 3D rendering to reduce crosstalk, then image quality is improved, but calculation complexity increases making real-time rendering difficult in low-performance devices
Solution Approach 1:
The patent transforms the complex Snell's law calculation into a simplified parameter-based adjustment system. By pre-calculating and storing correction values in lookup tables based on eye position parameters, the system replaces real-time trigonometric computations with simple table lookups and interpolations, maintaining image quality while reducing computational complexity for low-performance devices
Solution Approach 2:
The patent performs preliminary calculations of eye coordinate adjustments and stores them in advance in lookup tables. During real-time 3D rendering, the system only needs to query pre-computed values based on detected eye positions, avoiding complex Snell's law calculations at runtime and enabling real-time performance on low-power devices
2Reliability
If eye coordinates are adjusted using Snell's law to reduce crosstalk, then crosstalk is reduced, but processing time increases
Solution Approach 1:
The patent pre-computes eye coordinate adjustment values using Snell's law and stores them in lookup tables before runtime. During actual 3D rendering, the system quickly retrieves pre-calculated adjustment values based on detected eye positions, eliminating time-consuming trigonometric calculations and enabling real-time crosstalk compensation even on mobile devices with limited processing power
