Engineering Contradiction Analysis
1Reliability
If organic nonlinear optical material is crystallized to form a single member optical component, then terahertz wave generation and detection efficiency is improved, but manufacturing cost increases and yield ratio decreases
Solution Approach 1:
The patent uses a composite material consisting of organic nonlinear optical material particles dispersed in a transparent resin matrix. This composite approach allows the optical member to maintain terahertz wave generation and detection capabilities while avoiding the low yield and high cost associated with crystallizing pure organic nonlinear optical material into large single crystals.
2Reliability
If organic nonlinear optical material is crystallized to form a single member optical component, then terahertz wave generation and detection efficiency is improved, but manufacturing cost increases
Solution Approach 1:
The patent employs a composite structure where organic nonlinear optical material particles are embedded in a transparent resin. This eliminates the need for complex and costly crystallization processes required for pure organic nonlinear optical material, while still achieving effective terahertz wave generation and detection.
Solution Approach 2:
The patent uses relatively inexpensive organic nonlinear optical material particles and common transparent resins instead of expensive single crystal materials. This substitution of cheap materials for expensive ones significantly reduces manufacturing cost while maintaining functional performance.
3Reliability
If organic nonlinear optical material is crystallized to form a single member optical component, then optimal optical performance is achieved, but manufacturing time increases
Solution Approach 1:
The patent creates an optical member by dispersing organic nonlinear optical material particles in a transparent resin and forming a molded body. This composite fabrication process is much faster than the slow crystallization process required for single crystal optical components, significantly reducing manufacturing time.
