Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the number, arrangement, shape, thickness of electromagnetic devices are adjusted according to inherent optical properties of material, then the desired optical properties can be obtained, but the limitations and defects make it difficult to meet current and future demands for lighter, thinner, smaller electronic devices
Solution Approach 1:
The patent changes the fundamental parameter of refractive index by incorporating high-refractive-index materials (such as TiO2, SiO2, or Ge) into the photocurable resin matrix. This material parameter change enables achieving desired optical properties with thinner device structures, directly addressing the contradiction between optical performance and device miniaturization
Solution Approach 2:
The patent employs composite materials consisting of photocurable resin combined with high-refractive-index particles or nanomaterials. This composite approach enables simultaneous achievement of lightweight properties (from polymer matrix) and high optical performance (from high-index inclusions), resolving the contradiction between weight reduction and optical functionality
2Manufacturing precision
If the number, arrangement, shape, thickness of electromagnetic devices are adjusted according to inherent optical properties of material, then the desired optical properties can be obtained, but the limitations and defects make it difficult to meet current and future demands for lighter, thinner, smaller electronic devices
Solution Approach 1:
By changing the refractive index parameter through material selection and composition adjustment, the patent enables achieving the same optical performance with reduced device volume, as higher refractive index materials bend light more effectively, requiring less physical space for the same optical function
Solution Approach 2:
The composite material system allows tuning of effective refractive index through particle concentration and size, enabling compact device design with optimized optical performance without increasing volume
3Adaptability or versatility
If the material for adjusting refractive index and/or absorption coefficient is added to main material and mixed to form composite material, then the refractive index and/or absorption coefficient can be adjusted to obtain desired optical properties, but the manufacturing process becomes more complex
Solution Approach 1:
The patent merges the optical property adjustment function directly into the material formulation stage by pre-mixing high-refractive-index particles with photocurable resin. This combines multiple functions (structural integrity, optical performance, and refractive index tuning) into a single composite material system, simplifying the overall manufacturing process despite the added material complexity
