Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If bench tests are used to determine performance characteristics of photochromic lenses, then measurement can be performed in controlled environment, but the results only provide partial answer regarding actual behavior in outdoor environment
Solution Approach 1:
The patent introduces computational models and simulation algorithms as intermediaries between controlled bench test data and actual outdoor performance. These models act as mediators that translate laboratory measurements into predictive outdoor characteristics by incorporating environmental variables, wearer habits, and physiological factors that cannot be directly measured in controlled settings.
Solution Approach 2:
The patent creates virtual copies of outdoor testing conditions through computational simulations. Instead of physically testing lenses in diverse outdoor environments, the system replicates various outdoor scenarios (different climates, times of day, weather conditions) through digital models that process bench test data to predict real-world performance.
2Adaptability or versatility
If individual wearer needs and environmental factors are considered for lens selection, then suitable photochromic lens can be selected for individual wearer, but the selection process becomes more complex
Solution Approach 1:
The patent creates a multi-functional selection system that simultaneously evaluates multiple wearer needs (glare sensitivity, temperature sensitivity, lifestyle habits) and environmental factors (climate, geography, time of day) through a single integrated computational platform. This universal system handles diverse input parameters and generates comprehensive lens recommendations without requiring separate analysis processes for each factor.
Solution Approach 2:
The patent transforms complex qualitative wearer preferences and environmental conditions into quantifiable parameters that can be processed computationally. By converting subjective factors (glare sensitivity, comfort preferences) into measurable variables and assigning numerical weights to different environmental conditions, the system simplifies the decision-making process while maintaining personalized accuracy.
