Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If refractive/diffractive optical technologies are used for light management, then light output can be controlled, but display thickness increases and assembly becomes complicated
Solution Approach 1:
The patent changes the optical management approach from refractive/diffractive to meta-optical, using sub-wavelength structures that manipulate light through phase modulation rather than traditional refraction. This parameter change in the optical mechanism enables thinner display construction while maintaining light control capability
Solution Approach 2:
The patent replaces bulky mechanical refractive/diffractive optical components with planar meta-optical structures that achieve the same light management function through nanoscale patterning. This substitution eliminates the need for thick optical elements and complex assembly mechanisms
2Illumination intensity
If refractive/diffractive optical technologies are used for light management, then light output can be controlled, but assembly complexity increases
Solution Approach 1:
The patent merges the meta-optical structures directly with the display panel layers, integrating light management functionality into the existing display architecture. This merging eliminates separate assembly steps for optical components and simplifies the overall assembly process
Solution Approach 2:
The patent replaces complex mechanical assembly of refractive/diffractive optical elements with a simplified planar meta-optical structure that can be manufactured using standard semiconductor fabrication techniques, reducing assembly complexity
3Reliability
If traditional optical technologies are used, then display performance can be achieved, but manufacturing costs increase
Solution Approach 1:
The patent changes the manufacturing approach from traditional optical component assembly to meta-optical structure fabrication using established semiconductor processes. This parameter change enables production using existing manufacturing infrastructure, reducing costs while maintaining display performance
Solution Approach 2:
The patent replaces expensive traditional optical component manufacturing and assembly with cost-effective meta-optical structure fabrication using standard semiconductor manufacturing techniques, achieving the same performance at lower cost
