Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional glass materials are used to maintain mechanical strength and thermal properties, then reliability is improved, but light transmissivity is reduced
Solution Approach 1:
The glass material is segmented into multiple nanoparticles (0.1-10 nm in size) that are stacked to form the optical component. This segmentation allows light to pass through the interstices between particles while the collective arrangement maintains mechanical strength and thermal properties.
Solution Approach 2:
Different regions of the optical component have different nanoparticle concentrations and arrangements. The surface regions are optimized for light transmissivity with lower particle density, while internal regions maintain higher density for mechanical strength, creating local quality variations that resolve the contradiction.
2Illumination intensity
If nanoparticle stacks are used to improve light transmissivity, then illumination intensity is improved, but manufacturing precision is reduced
Solution Approach 1:
A binder material serves as an intermediary substance that holds the nanoparticles together in a stack configuration. This binder facilitates the assembly of nanoparticles into functional structures without requiring precise positioning of each individual particle, thus improving manufacturability while maintaining optical performance.
3Strength
If inorganic fillers with SiO2 films are used to improve mechanical characteristics, then strength is improved, but light transmissivity is reduced
Solution Approach 1:
The patent creates a composite material system consisting of inorganic filler particles coated with SiO2 films, embedded in a polymer matrix. The SiO2 coating provides mechanical strength and adhesion, while the nanoscale particle size and optimized concentration (1-50 wt%) allow sufficient light transmission, resolving the contradiction between strength and transmissivity.
