Engineering Contradiction Analysis
1Measurement precision
If traditional techniques for simulating nonlinear response of materials are used, then computational accuracy can be achieved, but device complexity and implementation difficulty increase significantly
Solution Approach 1:
The patent divides the complex simulation process into separate computational blocks: propagation block for electromagnetic radiation propagation and transition blocks for various optical transitions (absorption, emission, scattering, etc.). This segmentation allows each block to be independently developed, tested, and combined, reducing overall system complexity while maintaining accuracy.
Solution Approach 2:
The patent creates a universal framework that can handle multiple types of optical interactions through a single software architecture. The same propagation block works with different transition blocks for various materials and processes, making the software versatile without requiring separate programs for each simulation type.
2Reliability
If conventional simulation methods are used, then specific material characteristics can be modeled, but adaptability to different material compositions and optical interactions is limited
Solution Approach 1:
The patent separates material-specific transition processes from the general propagation framework. Users can select different transition blocks (absorption, emission, scattering) and combine them with propagation blocks to simulate various material compositions and optical interactions using the same base software architecture.
Solution Approach 2:
The patent allows users to adjust parameters such as wavelength, material composition, and optical properties to model different scenarios. The software can accommodate changes in material characteristics without requiring fundamental algorithm changes, enhancing adaptability while maintaining model accuracy.
3Productivity
If traditional propagation/transmission analyses are used, then simplified calculations can be performed, but measurement precision is reduced due to neglect of molecular excited states
Solution Approach 1:
The patent segments the simulation into propagation and transition components, allowing the propagation block to maintain computational efficiency while the transition blocks handle complex molecular excited state processes. This separation enables detailed modeling without proportionally increasing overall computational cost.
Solution Approach 2:
The patent implements a balanced approach by including only the necessary transition processes for each specific simulation case. Users can select which transition blocks to activate based on the material and optical conditions, avoiding unnecessary computational complexity while maintaining sufficient precision for accurate results.
4Measurement precision
If comprehensive modeling of multiple transition processes is implemented, then accuracy of simulating complex optical interactions is improved, but computational cost increases
Solution Approach 1:
The patent divides computational tasks into separate blocks that can be selectively activated. Users can combine only the necessary propagation and transition blocks for their specific simulation needs, reducing overall computational cost while maintaining accuracy for the modeled processes.
Solution Approach 2:
The patent provides flexibility in selecting which transition processes to model based on the specific application. Users can activate only the necessary transition blocks (e.g., absorption only, or absorption plus emission) to balance computational cost with the required level of accuracy for their particular optical interaction simulation.
