Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If indirect light measurement is used (measuring reflected light on surfaces), then environmental influences can be measured, but measurement precision is reduced and the true light source parameters cannot be accurately determined
Solution Approach 1:
The patent introduces a mobile device as an intermediary measurement tool that can directly measure light source parameters while also detecting environmental factors. This mediator bridges the gap between precise light measurement and environmental context detection, allowing both objectives to be achieved simultaneously without the trade-off present in indirect measurement systems.
Solution Approach 2:
The measurement system is segmented into distinct functional components: the mobile device handles direct light source measurement while separately detecting environmental influences. This segmentation allows each component to optimize its measurement function independently, achieving both high precision and environmental adaptability.
2Adaptability or versatility
If lighting parameters are not adjusted based on physiological criteria, then system complexity is reduced, but user well-being and personalized control are compromised
Solution Approach 1:
The system enables self-service configuration where the mobile device automatically detects light source parameters and facilitates user-defined adjustments without requiring complex manual configuration procedures. The system serves itself by providing intuitive interfaces that guide users through personalized lighting setup based on their physiological needs.
Solution Approach 2:
The system performs preliminary measurement of light source parameters and environmental conditions before user configuration. This preliminary action provides the foundation for personalized lighting control, allowing the system to pre-process data and present optimized configuration options to users, thereby reducing the perceived complexity.
3Measurement precision
If address assignment requires position determination devices, then positioning accuracy is improved, but device complexity and configuration difficulty increase
Solution Approach 1:
The mobile device serves multiple functions: it measures light source parameters, determines position for address assignment, and facilitates user configuration. This multi-functionality eliminates the need for separate dedicated positioning devices, reducing overall system complexity while maintaining positioning accuracy through the mobile device's integrated capabilities.
