Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the diffusion module thickness is increased to reduce pixelization, then the sense of grain is improved, but the image becomes overly blurred
Solution Approach 1:
The patent applies parameter changes by precisely controlling the diffusion module thickness (T) and haze (Haze) within specific ranges defined by the formula 0.003 < T/Haze < 0.015. This mathematical relationship establishes optimal parameter combinations that balance grain reduction and blur control, transforming the diffusion module from a simple component into a precisely tuned optical element that resolves the contradiction between pixelization and image clarity.
