Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a light control member uses a uniform structure throughout, then manufacturing is simpler, but light conversion efficiency is reduced
Solution Approach 1:
The light control member employs a non-uniform structure with a first region containing organic monomers and inorganic material, and a second region containing inorganic material dispersed in an organic polymer. This local differentiation optimizes light conversion efficiency in specific zones while maintaining manufacturing feasibility through a structured approach.
2Loss of energy
If the concentration of inorganic material is increased throughout the light control member, then light conversion efficiency is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The inorganic material concentration is strategically varied: the first region has a higher concentration to maximize light conversion where needed, while the second region has a lower concentration to reduce manufacturing complexity and cost. This localized optimization resolves the contradiction between efficiency and complexity.
3Loss of energy
If the thickness of the light control member is increased, then light conversion efficiency is improved, but display quality and reliability deteriorate
Solution Approach 1:
The light control member is divided into regions with different thicknesses: the first region has a smaller thickness optimized for light conversion efficiency, while the second region has a larger thickness that maintains display quality and reliability. This localized thickness variation resolves the contradiction between conversion efficiency and reliability.
4Loss of energy
If organic monomers are used throughout the light control member, then light conversion efficiency is improved, but manufacturing cost and complexity increase
Solution Approach 1:
Organic monomers are concentrated in the first region where they provide superior light conversion efficiency, while the second region uses an organic polymer matrix that is more cost-effective and simpler to manufacture. This localized material distribution resolves the contradiction between efficiency and manufacturing cost.
