Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If actual optical emitter materials are used for studies, then accurate optical behavior characterization is achieved, but high costs and material availability restrictions occur
Solution Approach 1:
The patent creates a virtual copy of the optical emitter through a simulation model that replicates the optical behavior characteristics. This digital twin allows researchers to study optical properties without needing physical material samples, thereby resolving the contradiction between measurement accuracy and material availability.
Solution Approach 2:
The patent introduces a simulation model as an intermediary between the researcher and the actual optical emitter. This mediator enables indirect observation and analysis of optical behavior, eliminating the need for direct physical material interaction while maintaining characterization accuracy.
2Measurement precision
If actual optical emitter materials are used for studies, then accurate optical behavior characterization is achieved, but high costs occur
Solution Approach 1:
By creating a virtual replica of the optical emitter through simulation, the patent eliminates the need for expensive physical material acquisition and consumption. The simulation model can be reused indefinitely without additional material costs, resolving the contradiction between measurement accuracy and study cost.
Solution Approach 2:
The patent replaces expensive, potentially single-use physical materials with a reusable computational simulation model. This digital substitute has negligible marginal cost for repeated use, thereby eliminating the high recurring costs associated with physical material studies.
3Loss of information
If optical emitter materials are consumed during studies, then comprehensive characterization is achieved, but material loss occurs
Solution Approach 1:
The patent creates a persistent virtual copy of the optical emitter that can be studied repeatedly without degradation or consumption. This digital twin preserves all optical behavior information indefinitely, eliminating material loss while maintaining complete characterization capability.
Solution Approach 2:
The patent performs comprehensive virtual characterization studies before any physical material is used. The simulation model allows complete optical behavior analysis to be conducted in advance, eliminating the need for subsequent material-consuming experimental verification.
