Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a catalogue with limited real samples is used for color selection, then the device complexity is reduced, but the adaptability and color range are limited
Solution Approach 1:
The patent creates a virtual catalog containing simulated color representations generated from databases of optical properties and simulation modules. Instead of maintaining a physical catalog with limited real samples, the system generates virtual color representations through computational simulation, thereby expanding the available color range without proportionally increasing physical device complexity
Solution Approach 2:
The system varies multiple parameters including dye concentrations, layer thicknesses, and optical properties in the simulation database to generate a wide range of color variations. By changing these parameters computationally, the system achieves high adaptability and color versatility without requiring physical prototypes for each variation
2Measurement precision
If numerous trial and errors are performed for color matching, then the measurement precision is improved, but the time consumption increases
Solution Approach 1:
The patent pre-calculates and stores databases containing optical properties, absorption coefficients, and simulated colorimetric data for various dye combinations and layer configurations. This preliminary computational work enables rapid color matching during actual use without requiring repeated trial-and-error measurements, thus improving precision while reducing time consumption
Solution Approach 2:
The system incorporates color matching algorithms that compare target colors with simulated results and provide feedback for optimization. The simulation modules iteratively adjust dye concentrations and layer parameters based on color difference calculations, enabling precise color matching through automated feedback loops rather than manual trial and error
3Reliability
If technical spectral filters are added to lenses, then the functional performance is improved, but the color matching difficulty increases
Solution Approach 1:
The patent integrates the simulation of technical spectral filters directly into the color matching simulation modules. The database combines optical properties of dyes, substrates, and spectral filters into a unified simulation framework, allowing simultaneous optimization of both spectral performance and color appearance without requiring separate matching processes
4Adaptability or versatility
If a comprehensive database with extensive color data is created, then the adaptability is improved, but the device complexity and data processing requirements increase
Solution Approach 1:
The patent organizes the comprehensive database into segmented modules: substrate optical properties database, dye absorption coefficients database, layer configuration database, and simulation result database. This segmentation allows the system to handle extensive color data through modular processing, improving adaptability while managing database complexity through structured organization
